Prospectus Supplement

 

 

Certain matters discussed in this prospectus supplement and the documents incorporated herein by reference, excluding historical information, include “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These forward-looking statements relate to anticipated financial performance, management’s plans and objectives for future operations, business prospects, outcome of regulatory proceedings, market conditions, and other matters.

 

All statements, other than statements of historical facts, included in this prospectus supplement that address activities, events or developments that we expect, believe or anticipate will exist or may occur in the future are forward-looking statements. Forward-looking statements can be identified by various forms of words such as “anticipates,” “believes,” “seeks,” “could,” “may,” “should,” “continues,” “estimates,” “expects,” “forecasts,” “intends,” “might,” “goals,” “objectives,” “targets,” “planned,” “potential,” “projects,” “scheduled,” “will,” or other similar expressions. These statements are based on management’s beliefs and assumptions and on information currently available to management and include, among others, statements regarding:

 

 

Forward-looking statements are based on numerous assumptions, uncertainties, and risks that could cause future events or results to be materially different from those stated or implied in this prospectus supplement or in the documents incorporated herein by reference. You should carefully consider the risk factors discussed below in addition to the other information in this prospectus supplement. If any of the following risks were actually to occur, our business, results of operations and financial condition could be materially adversely affected. Many of the factors that will determine these results are beyond our ability to control or predict. Specific factors that could cause actual results to differ from results contemplated by the forward-looking statements include, among others, the following:

 

 

 

Given the uncertainties and risk factors that could cause our actual results to differ materially from those contained in any forward-looking statement, we caution investors not to unduly rely on our forward-looking statements. We disclaim any obligations to and do not intend to update the above list or to announce publicly the result of any revisions to any of the forward-looking statements to reflect future events or developments.

 

In addition to causing our actual results to differ, the factors listed above and referred to below may cause our intentions to change from those statements of intention set forth in or incorporated into this prospectus supplement. Such changes in our intentions may also cause our results to differ. We may change our intentions, at any time and without notice, based upon changes in such factors, our assumptions, or otherwise.

 

Because forward-looking statements involve risks and uncertainties, we caution that there are important factors, in addition to those listed above, that may cause actual results to differ materially from those contained in the forward-looking statements. These factors include the risks set forth under the caption “Risk Factors” in this prospectus supplement and in our Annual Report on Form 10-K for the year ended December 31, 2009 (the “2009 10-K”), incorporated by reference in this prospectus supplement, and our Quarterly Reports on Form 10-Q for the quarterly periods ended March 31, 2010, June 30, 2010 and September 30, 2010 (the “2010 10-Qs”), incorporated by reference in this prospectus supplement.

See “Certain Definitions” for definitions of certain terms used in this section.

 

Risks Related to the Notes

 

Our partnership agreement limits our ability to accumulate cash, which may limit cash available to service the notes or to repay them at maturity.

 

Our partnership agreement requires us to distribute on a quarterly basis, 100% of our available cash to our unitholders of record and our general partner. Available cash is generally all of our cash on hand at the end of each quarter, after payment of fees and expenses and the establishment of cash reserves by our general partner. Our general partner determines the amount and timing of cash distributions and has broad discretion to establish and make additions to our reserves or the reserves of our operating subsidiaries in amounts our general partner determines to be necessary or appropriate:

 

 

Depending on the timing and amount of our cash distributions to unitholders and because we are not required to accumulate cash for the purpose of meeting obligations to holders of any notes, such distributions could significantly reduce the cash available to us in subsequent periods to pay the interest on, and principal of, the notes.

 

Our indebtedness could impair our financial condition and our ability to fulfill our debt obligations, including our obligations under the notes.

 

As of September 30, 2010, we had outstanding indebtedness of $6.2 billion, representing approximately 59% of our total book capitalization. As of September 30, 2010, after giving effect to this offering and the consummation of the Midstream Piceance Acquisition, we would have had outstanding indebtedness of $      billion, representing approximately     % of our total book capitalization.

 

Our debt service obligations and restrictive covenants in the Credit Facility, the indenture governing the notes and the indentures governing our existing senior unsecured notes could have important consequences to you. For example, they could:

 

 

 

Our ability to repay, extend or refinance our existing debt obligations, to make payments of interest on, and the principal of, the notes, and to obtain future credit will depend primarily on our operating performance, which will be affected by general economic, financial, competitive, legislative, regulatory, business and other factors, many of which are beyond our control. Our ability to refinance existing debt obligations or obtain future credit will also depend upon the current conditions in the credit markets and the availability of credit generally. If we are unable to meet our debt service obligations, we could be forced to restructure or refinance our indebtedness, seek additional equity capital or sell assets. We may be unable to obtain financing or sell assets on satisfactory terms, or at all.

 

We are not prohibited under the indenture that will govern the notes or the indentures that govern our existing senior unsecured notes from incurring additional indebtedness in addition to the notes. Our incurrence of significant additional indebtedness would exacerbate the negative consequences mentioned above, and could adversely affect our ability to pay the interest on, and principal of, the notes.

 

We have a holding company structure in which our subsidiaries conduct our operations and own our operating assets, which may affect our ability to make payments on the notes.

 

We have a holding company structure, and our subsidiaries conduct all of our operations and own all of our operating assets. We have no significant assets other than the ownership interests in these subsidiaries. As a result, our ability to make required payments on the notes depends on the performance of our subsidiaries and their ability to distribute funds to us. The ability of our subsidiaries to make distributions to us may be restricted by, among other things, applicable state partnership and limited liability company laws and other laws and regulations. If we are unable to obtain the funds necessary to pay the principal amount at maturity of the notes, we may be required to adopt one or more alternatives, such as a refinancing of the notes. We cannot assure you that we would be able to refinance the notes.

 

Our debt agreements and Williams’ public indentures contain financial and operating restrictions that may limit our access to credit and affect our ability to operate our business. In addition, our ability to obtain credit in the future will be affected by Williams’ credit ratings.

 

Our public indentures contain various covenants that, among other things, limit our ability to grant certain liens to support indebtedness, merge, or sell substantially all of our assets. In addition, our Credit Facility contains certain financial covenants and restrictions on our ability and our subsidiaries’ ability to incur indebtedness, to consolidate or allow any material change in the nature of our business, enter into certain affiliate transactions and make certain distributions during an event of default. These covenants could adversely affect our ability to finance our future operations or capital needs or engage in, expand or pursue our business activities and prevent us from engaging in certain transactions that might otherwise be considered beneficial to us. Our ability to comply with these covenants may be affected by events beyond our control, including prevailing economic, financial and industry conditions. If market or other economic conditions deteriorate, our current assumptions about future economic conditions turn out to be incorrect or unexpected events occur, our ability to comply with these covenants may be significantly impaired.

 

Williams’ public indentures contain covenants that restrict Williams’ and our ability to incur liens to support indebtedness. These covenants could adversely affect our ability to finance our future operations or capital needs or engage in, expand or pursue our business activities and prevent us from engaging in certain transactions that might otherwise be considered beneficial to us. Williams’ ability to comply with the covenants contained in its debt instruments may be affected by events beyond our and Williams’ control, including prevailing economic, financial

and industry conditions. If market or other economic conditions deteriorate, Williams’ ability to comply with these covenants may be negatively impacted.

 

Our failure to comply with the covenants in our debt agreements could result in events of default. Upon the occurrence of such an event of default, the lenders could elect to declare all amounts outstanding under a particular facility to be immediately due and payable and terminate all commitments, if any, to extend further credit. Certain payment defaults or an acceleration under our public indentures or other material indebtedness could cause a cross-default or cross-acceleration of our Credit Facility. Such a cross-default or cross-acceleration could have a wider impact on our liquidity than might otherwise arise from a default or acceleration of a single debt instrument. If an event of default occurs, or if our Credit Facility cross-defaults, and the lenders under the affected debt agreements accelerate the maturity of any loans or other debt outstanding to us, we may not have sufficient liquidity to repay amounts outstanding under such debt agreements. For more information regarding our debt agreements, please read “Description of Other Indebtedness” in this prospectus supplement and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2009 10-K and in our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2010 (the “Third Quarter 2010 10-Q”).

 

Substantially all of Williams’ operations are conducted through its subsidiaries. Williams’ cash flows are substantially derived from loans, dividends and distributions paid to it by its subsidiaries. Williams’ cash flows are typically utilized to service debt and pay dividends on the common stock of Williams, with the balance, if any, reinvested in its subsidiaries as loans or contributions to capital. Due to our relationship with Williams, our ability to obtain credit will be affected by Williams’ credit ratings. If Williams were to experience a deterioration in its credit standing or financial condition, our access to credit and our ratings could be adversely affected. Any future downgrading of a Williams’ credit rating would likely also result in a downgrading of our credit rating. A downgrading of a Williams’ credit rating could limit our ability to obtain financing in the future upon favorable terms, if at all.

 

Our subsidiaries are not prohibited from incurring indebtedness by their organizational documents, which may affect our ability to pay interest on, and the principal of, the notes.

 

Our subsidiaries are not prohibited by the terms of their respective organizational documents from incurring indebtedness. If they were to incur significant amounts of indebtedness, such occurrence may inhibit their ability to make distributions to us. An inability by our subsidiaries to make distributions to us would materially and adversely affect our ability to pay interest on, and the principal of, the notes because we expect distributions we receive from our subsidiaries to represent a significant portion of the cash we use to pay interest on, and the principal of, the notes.

 

The notes will be structurally subordinated to liabilities and indebtedness of our subsidiaries and effectively subordinated to any of our secured indebtedness to the extent of the assets securing such indebtedness.

 

We currently have no secured indebtedness outstanding, but holders of any secured indebtedness that we may incur in the future would have claims with respect to our assets constituting collateral for such indebtedness that are effectively prior to your claims under the notes. In the event of a default on such secured indebtedness or our bankruptcy, liquidation or reorganization, those assets would be available to satisfy obligations with respect to the indebtedness secured thereby before any payment could be made on the notes. Accordingly, any such secured indebtedness would effectively be senior to the notes to the extent of the value of the collateral securing the indebtedness. While the indenture governing the notes places some limitations on our ability to create liens, there are significant exceptions to these limitations that will allow us to secure some kinds of indebtedness without equally and ratably securing the notes. To the extent the value of the collateral is not sufficient to satisfy the secured indebtedness, the holders of that indebtedness would be entitled to share with the holders of the notes and the holders of other claims against us with respect to our other assets. Holders of the notes will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same class as the notes, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets. In any of the foregoing events, we cannot assure you that there will be sufficient assets to pay amounts due on the notes. As a result, holders of notes may receive less, ratably, than holders of secured indebtedness.

In addition, the notes are not guaranteed by our subsidiaries and our subsidiaries are generally not prohibited under the indenture from incurring additional indebtedness (in particular, Transco and Northwest Pipeline collectively had approximately $2 billion of indebtedness outstanding as of September 30, 2010 and are likely to incur additional indebtedness in the future). As a result, holders of the notes will be structurally subordinated to claims of third party creditors, including holders of indebtedness, of these subsidiaries. Claims of those other creditors, including trade creditors, secured creditors, governmental authorities, and holders of indebtedness or guarantees issued by the subsidiaries, will generally have priority as to the assets of the subsidiaries over claims by the holders of the notes. As a result, rights of payment of holders of our indebtedness, including the holders of the notes, will be structurally subordinated to all those claims of creditors of our subsidiaries.

 

Cost reimbursements due to our general partner and its affiliates will reduce cash available to pay interest on, and the principal of, the notes.

 

We reimburse our general partner and its affiliates, including Williams, for various general and administrative services they provide for our benefit, including costs for rendering administrative staff and support services to us, and overhead allocated to us. Our general partner determines the amount of these reimbursements in its sole discretion. Payments for these services will be substantial and will reduce the amount of cash available for payments of interest on, and the principal of, the notes. In addition, under Delaware partnership law, our general partner has unlimited liability for our obligations, such as our debts and environmental liabilities, except for our contractual obligations that are expressly made without recourse to our general partner. To the extent our general partner incurs obligations on our behalf, we are obligated to reimburse or indemnify it. If we are unable or unwilling to reimburse or indemnify our general partner, our general partner may take actions to cause us to make payments of these obligations and liabilities. Any such payments adversely affect our ability to pay interest on, and the principal of, the notes.

 

An active trading market may not develop for our notes.

 

Prior to this offering, there was no market for the notes. We have been informed by the underwriters that they intend to make a market in the notes after this offering is completed. However, none of the underwriters is obligated to make a market in the notes and, even if the underwriters commence market making, they may cease their market-making at any time. In addition, the liquidity of the trading market in the notes and the market price quoted for the notes may be adversely affected by changes in the overall market for debt securities and by changes in our financial performance or prospects or in the financial performance or prospects of companies in our industry. As a result, an active trading market may not develop or be maintained for our notes. If an active market does not develop or is not maintained, the market price and liquidity of our notes may be adversely affected.

 

Risks Inherent in Our Business

 

We may not be able to grow or effectively manage our growth.

 

A principal focus of our strategy is to continue to grow by expanding our business. Our future growth will depend upon our ability to successfully identify, finance, acquire, integrate and operate projects and businesses. Failure to achieve any of these factors would adversely affect our ability to achieve anticipated growth in the level of cash flows or realize anticipated benefits.

 

We may acquire new facilities or expand our existing facilities to capture anticipated future growth in natural gas production that does not ultimately materialize. As a result, our new or expanded facilities may not achieve profitability. In addition, the process of integrating newly acquired or constructed assets into our operations may result in unforeseen operating difficulties, may absorb significant management attention and may require financial resources that would otherwise be available for the ongoing development and expansion of our existing operations. Future acquisitions or construction projects may require substantial new capital and could result in the incurrence of indebtedness, additional liabilities and excessive costs that could have a material adverse effect on our business, results of operations, financial condition and our ability to pay interest on, and the principal of, the notes. Further, any limitations on our access to capital, including limitations caused by illiquidity in the capital markets, may impair our ability to complete future acquisitions and construction projects on favorable terms, if at all.

Prices for NGLs, natural gas and other commodities are volatile, and this volatility could adversely affect our financial results, cash flows, access to capital and ability to maintain existing businesses.

 

Our revenues, operating results, future rate of growth and the value of certain segments of our businesses depend primarily upon the prices of NGLs, natural gas, or other commodities, and the differences between prices of these commodities. Price volatility can impact both the amount we receive for our products and services and the volume of products and services we sell. Prices affect the amount of cash flow available for capital expenditures and our ability to borrow money or raise additional capital. Any of the foregoing can also have an adverse effect on our business, results of operations and financial condition and our ability to pay interest on, and the principal of, the notes.

 

The markets for NGLs, natural gas and other commodities are likely to continue to be volatile. Wide fluctuations in prices might result from relatively minor changes in the supply of and demand for these commodities, market uncertainty and other factors that are beyond our control, including:

 

 

We might not be able to successfully manage the risks associated with selling and marketing products in the wholesale energy markets.

 

Our portfolio of derivative and other energy contracts may consist of wholesale contracts to buy and sell commodities, including contracts for natural gas, NGLs and other commodities that are settled by the delivery of the commodity or cash throughout the United States. If the values of these contracts change in a direction or manner that we do not anticipate or cannot manage, it could negatively affect our results of operations. In the past, certain marketing and trading companies have experienced severe financial problems due to price volatility in the energy commodity markets. In certain instances this volatility has caused companies to be unable to deliver energy commodities that they had guaranteed under contract. If such a delivery failure were to occur in one of our contracts, we might incur additional losses to the extent of amounts, if any, already paid to, or received from, counterparties. In addition, in our businesses, we often extend credit to our counterparties. Despite performing credit analysis prior to extending credit, we are exposed to the risk that we might not be able to collect amounts owed to us. If the counterparty to such a transaction fails to perform and any collateral that secures our counterparty’s obligation is inadequate, we will suffer a loss. Downturns in the economy or disruptions in the global credit markets could cause more of our counterparties to fail to perform than we expect.

Any decrease in NGL prices or a change in NGL prices relative to the price of natural gas could affect our processing, fractionation and storage businesses.

 

The relationship between natural gas prices and NGL prices affects our profitability. When natural gas prices are low relative to NGL prices, it is more profitable for us and our customers to process natural gas. When natural gas prices are high relative to NGL prices, it is less profitable to process natural gas both because of the higher value of natural gas and because of the increased cost of separating the mixed NGLs from the natural gas. Higher natural gas prices relative to NGL prices may also make it uneconomical to recover ethane, which may further negatively impact sales volumes and margins. Finally, higher natural gas prices relative to NGL prices could also reduce volumes of gas processed generally, reducing the volumes of mixed NGLs available for fractionation.

 

The long-term financial condition of our natural gas transportation and midstream businesses is dependent on the continued availability of natural gas supplies in the supply basins that we access, demand for those supplies in our traditional markets, and the prices of and market demand for natural gas.

 

The development of the additional natural gas reserves that are essential for our gas transportation and midstream businesses to thrive requires significant capital expenditures by others for exploration and development drilling and the installation of production, gathering, storage, transportation and other facilities that permit natural gas to be produced and delivered to our pipeline systems. Low prices for natural gas, regulatory limitations, including environmental regulations, or the lack of available capital for these projects could adversely affect the development and production of additional reserves, as well as gathering, storage, pipeline transportation and import and export of natural gas supplies, adversely impacting our ability to fill the capacities of our gathering, transportation and processing facilities.

 

Production from existing wells and natural gas supply basins with access to our pipeline systems will also naturally decline over time. The amount of natural gas reserves underlying these wells may also be less than anticipated, and the rate at which production from these reserves declines may be greater than anticipated. Additionally, the competition for natural gas supplies to serve other markets could reduce the amount of natural gas supply for our customers. Accordingly, to maintain or increase the contracted capacity or the volume of natural gas transported on our pipeline systems and cash flows associated with the transportation of natural gas, our customers must compete with others to obtain adequate supplies of natural gas. In addition, if natural gas prices in the supply basins connected to our pipeline systems are higher than prices in other natural gas producing regions, our ability to compete with other transporters may be negatively impacted on a short-term basis, as well as with respect to our long-term recontracting activities. If new supplies of natural gas are not obtained to replace the natural decline in volumes from existing supply areas, if natural gas supplies are diverted to serve other markets, or if environmental regulators restrict new natural gas drilling, the overall volume of natural gas transported and stored on our system would decline, which could have a material adverse effect on our business, financial condition and results of operations, and our ability to pay interest on, and the principal of, the notes. In addition, new LNG import facilities built near our markets could result in less demand for our gathering and transportation facilities.

 

Our risk measurement and hedging activities might not be effective and could increase the volatility of our results.

 

Although we have systems in place that use various methodologies to quantify commodity price risk associated with our businesses, these systems might not always be followed or might not always be effective. Further, such systems do not in themselves manage risk, particularly risks outside of our control, and adverse changes in energy commodity market prices, volatility, adverse correlation of commodity prices, the liquidity of markets, changes in interest rates and other risks discussed in this prospectus supplement might still adversely affect our earnings, cash flows and balance sheet under applicable accounting rules, even if risks have been identified.

 

In an effort to manage our financial exposure related to commodity price and market fluctuations, we have entered and may in the future enter into contracts to hedge certain risks associated with our assets and operations. In these hedging activities, we have used and may in the future use fixed-price, forward, physical purchase and sales contracts, futures, financial swaps and option contracts traded in the over-the-counter markets or on exchanges.

Nevertheless, no single hedging arrangement can adequately address all risks present in a given contract. For example, a forward contract that would be effective in hedging commodity price volatility risks would not hedge the contract’s counterparty credit or performance risk. Therefore, unhedged risks will always continue to exist. While we attempt to manage counterparty credit risk within guidelines established by our credit policy, we may not be able to successfully manage all credit risk and as such, future cash flows and results of operations could be impacted by counterparty default.

 

Our use of hedging arrangements through which we attempt to reduce the economic risk of our participation in commodity markets could result in increased volatility of our reported results. Changes in the fair values (gains and losses) of derivatives that qualify as hedges under generally accepted accounting principles (“GAAP”), to the extent that such hedges are not fully effective in offsetting changes to the value of the hedged commodity, as well as changes in the fair value of derivatives that do not qualify or have not been designated as hedges under GAAP, must be recorded in our income. This creates the risk of volatility in earnings even if no economic impact to us has occurred during the applicable period.

 

The impact of changes in market prices for NGLs and natural gas on the average prices paid or received by us may be reduced based on the level of our hedging activities. These hedging arrangements may limit or enhance our margins if the market prices for NGLs or natural gas were to change substantially from the price established by the hedges. In addition, our hedging arrangements expose us to the risk of financial loss in certain circumstances, including instances in which:

 

 

The adoption and implementation of new statutory and regulatory requirements for derivative transactions could have an adverse impact on our ability to hedge risks associated with our business and increase the working capital requirements to conduct these activities.

 

In July 2010, federal legislation known as the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) was enacted. The Dodd-Frank Act provides for new statutory and regulatory requirements for derivative transactions, including oil and gas hedging transactions. Among other things, the Dodd-Frank Act provides for the creation of position limits for certain derivatives transactions, as well as requiring certain transactions to be cleared on exchanges for which cash collateral will be required. The final impact of the Dodd-Frank Act on our hedging activities is uncertain at this time due to the requirement that the SEC and the Commodities Futures Trading Commission (the “CFTC”) promulgate rules and regulations implementing the new legislation within 360 days from the date of enactment. These new rules and regulations could significantly increase the cost of derivative contracts, materially alter the terms of derivative contracts or reduce the availability of derivatives. Although we believe the derivative contracts that we enter into should not be impacted by position limits and should be exempt from the requirement to clear transactions through a central exchange or to post collateral, the impact upon our businesses will depend on the outcome of the implementing regulations adopted by the CFTC.

 

Depending on the rules and definitions adopted by the CFTC, we might in the future be required to provide cash collateral for our commodities hedging transactions under circumstances in which we do not currently post cash collateral. Posting of such additional cash collateral could impact liquidity and reduce our cash available for capital expenditures or other partnership purposes. A requirement to post cash collateral could therefore reduce our ability to execute hedges to reduce commodity price uncertainty and thus protect cash flows. If we reduce our use of derivatives as a result of the Dodd-Frank Act and regulations, our results of operations may become more volatile and our cash flows may be less predictable, which could adversely affect our ability to plan for and fund capital expenditures.

Our industry is highly competitive, and increased competitive pressure could adversely affect our business and operating results.

 

We have numerous competitors in all aspects of our businesses, and additional competitors may enter our markets. Some of our competitors are large oil, natural gas and petrochemical companies that have greater access to supplies of natural gas and NGLs than we do. In addition, current or potential competitors may make strategic acquisitions or have greater financial resources than we do, which could affect our ability to make investments or acquisitions. Other companies with which we compete may be able to respond more quickly to new laws or regulations or emerging technologies or to devote greater resources to the construction, expansion or refurbishment of their facilities than we can. In addition, current or potential competitors may make strategic acquisitions or have greater financial resources than we do, which could affect our ability to make investments or acquisitions. There can be no assurance that we will be able to compete successfully against current and future competitors and any failure to do so could have a material adverse effect on our business, results of operations, and financial condition and our ability to pay interest on, and the principal of, the notes.

 

We are exposed to the credit risk of our customers, and our credit risk management may not be adequate to protect against such risk.

 

We are subject to the risk of loss resulting from nonpayment and/or nonperformance by our customers in the ordinary course of our business. Generally, our customers are rated investment grade, are otherwise considered creditworthy or are required to make prepayments or provide security to satisfy credit concerns. However, our credit procedures and policies may not be adequate to fully eliminate customer credit risk. We cannot predict to what extent our business would be impacted by deteriorating conditions in the economy, including declines in our customers’ creditworthiness. If we fail to adequately assess the creditworthiness of existing or future customers, unanticipated deterioration in their creditworthiness and any resulting increase in nonpayment and/or nonperformance by them could cause us to write down or write off doubtful accounts. Such write-downs or write-offs could negatively affect our operating results in the periods in which they occur, and, if significant, could have a material adverse effect on our business, results of operations, cash flows, and financial condition and our ability to pay interest on, and the principal of, the notes.

 

The failure of counterparties to perform their contractual obligations could adversely affect our operating results, financial condition and cash available to make distributions.

 

Despite performing credit analysis prior to extending credit, we are exposed to the credit risk of our contractual counterparties in the ordinary course of business even though we monitor these situations and attempt to take appropriate measures to protect ourselves. In addition to credit risk, counterparties to our commercial agreements, such as product sales, gathering, treating, storage, transportation, processing and fractionation agreements, may fail to perform their other contractual obligations. A failure of counterparties to perform their contractual obligations, including Williams, could cause us to write down or write off doubtful accounts, which could materially adversely affect our operating results, and financial condition and our ability to pay interest on, and the principal of, the notes.

 

If third-party pipelines and other facilities interconnected to our pipelines and facilities become unavailable to transport natural gas and NGLs or to treat natural gas, our revenues and cash available to pay distributions could be adversely affected.

 

We depend upon third-party pipelines and other facilities that provide delivery options to and from our pipelines and facilities for the benefit of our customers. Because we do not own these third-party pipelines or facilities, their continuing operation is not within our control. If these pipelines or facilities were to become temporarily or permanently unavailable for any reason, or if throughput were reduced because of testing, line repair, damage to pipelines or facilities, reduced operating pressures, lack of capacity, increased credit requirements or rates charged by such pipelines or facilities or other causes, we and our customers would have reduced capacity to transport, store or deliver natural gas or NGL products to end use markets or to receive deliveries of mixed NGLs, thereby reducing our revenues. Further, although there are laws and regulations designed to encourage competition in wholesale market transactions, some companies may fail to provide fair and equal access to their transportation systems or may not provide sufficient transportation capacity for other market participants.

Any temporary or permanent interruption at any key pipeline interconnect or in operations on third-party pipelines or facilities that would cause a material reduction in volumes transported on our pipelines or our gathering systems or processed, fractionated, treated or stored at our facilities could have a material adverse effect on our business, results of operations, and financial condition and our ability to repay the notes.

 

Future disruptions in the global credit markets may make equity and debt markets less accessible, create a shortage in the availability of credit and lead to credit market volatility, which could disrupt our financing plans and limit our ability to grow.

 

In 2008, public equity markets experienced significant declines, and global credit markets experienced a shortage in overall liquidity and a resulting disruption in the availability of credit. Future disruptions in the global financial marketplace, including the bankruptcy or restructuring of financial institutions, could make equity and debt markets inaccessible and adversely affect the availability of credit already arranged and the availability and cost of credit in the future. We have availability under our Credit Facility, but our ability to borrow under that facility could be impaired if one or more of our lenders fails to honor its contractual obligation to lend to us.

 

As a publicly traded partnership, these developments could significantly impair our ability to make acquisitions or finance growth projects. We distribute all of our available cash to our unitholders on a quarterly basis. We typically rely upon external financing sources, including the issuance of debt and equity securities and bank borrowings, to fund acquisitions or expansion capital expenditures. Any limitations on our access to external capital, including limitations caused by illiquidity or volatility in the capital markets, may impair our ability to complete future acquisitions and construction projects on favorable terms, if at all. As a result, we may be at a competitive disadvantage as compared to businesses that reinvest all of their available cash to expand ongoing operations, particularly under adverse economic conditions.

 

Adverse economic conditions could negatively affect our results of operations.

 

A slowdown in the economy has the potential to negatively impact our businesses in many ways. Included among these potential negative impacts are reduced demand and lower prices for our products and services, increased difficulty in collecting amounts owed to us by our customers and a reduction in our credit ratings (either due to tighter rating standards or the negative impacts described above), which could result in reducing our access to credit markets, raising the cost of such access or requiring us to provide additional collateral to our counterparties.

 

A downgrade of our credit rating could impact our liquidity, access to capital and our costs of doing business, and maintaining credit ratings is under the control of independent third parties.

 

A downgrade of our credit rating might increase our cost of borrowing and could require us to post collateral with third parties, negatively impacting our available liquidity. Our ability to access capital markets could also be limited by a downgrade of our credit rating and other disruptions. Such disruptions could include:

 

 

Credit rating agencies perform independent analysis when assigning credit ratings. The analysis includes a number of criteria including, but not limited to, business composition, market and operational risks, as well as various financial tests. Credit rating agencies continue to review the criteria for industry sectors and various debt ratings and may make changes to those criteria from time to time. Our current credit ratings from Moody’s is Baa3, from S&P is BBB-, and from Fitch is BBB-. Credit ratings are not recommendations to buy, sell or hold investments in the rated entity. Ratings are subject to revision or withdrawal at any time by the ratings agencies and no assurance can be given that we will maintain our current credit ratings.

We are subject to risks associated with climate change.

 

There is a growing belief that emissions of greenhouse gases may be linked to climate change. Climate change and the costs that may be associated with its impacts and the regulation of greenhouse gases have the potential to affect our business in many ways, including negatively impacting the costs we incur in providing our products and services, the demand for and consumption of our products and services (due to change in both costs and weather patterns), and the economic health of the regions in which we operate, all of which can create financial risks. For further information regarding risks to our business arising from climate change related regulation, please read the discussion below under “Our operations are subject to governmental laws and regulations relating to the protection of the environment, which may expose us to significant costs and liabilities and could exceed current expectations.”

 

Our assets and operations can be affected by weather and other natural phenomena.

 

Our assets and operations can be adversely affected by hurricanes, floods, earthquakes, tornadoes and other natural phenomena and weather conditions, including extreme temperatures, making it more difficult for us to realize the historic rates of return associated with these assets and operations. Insurance may be inadequate, and in some instances, we have been unable to obtain insurance on commercially reasonable terms or insurance has not been available at all. A significant disruption in operations or a significant liability for which we were not fully insured could have a material adverse effect on our business, results of operations and financial condition and our ability to pay interest on, and the principal of, the notes.

 

Our customers’ energy needs vary with weather conditions. To the extent weather conditions are affected by climate change or demand is impacted by regulations associated with climate change, customers’ energy use could increase or decrease depending on the duration and magnitude of the changes, leading either to increased investment or decreased revenues.

 

We depend on certain key customers and producers for a significant portion of our revenues and supply of natural gas and NGLs. If we lost any of these key customers or producers or contracted volumes, our revenues and cash available to pay distributions could decline.

 

We rely on a limited number of customers for a significant portion of our revenues. Although some of these customers are subject to long-term contracts, we may be unable to negotiate extensions or replacements of these contracts on favorable terms, if at all. The loss of all, or even a portion of, the revenues from natural gas, NGLs or contracted volumes, as applicable, supplied by these customers, as a result of competition, creditworthiness, inability to negotiate extensions or replacements of contracts or otherwise, could have a material adverse effect on our business, results of operations, financial condition and our ability to pay interest on, and the principal of, the notes, unless we are able to acquire comparable volumes from other sources.

 

We do not own all of the interests in Partially Owned Entities, which could adversely affect our ability to operate and control these assets in a manner beneficial to us.

 

Because we do not control the Partially Owned Entities, our investments in which account for approximately 8% of our total consolidated assets at September 30, 2010, we may have limited flexibility to control the operation of or cash distributions received from these assets. Any future disagreements with the other co-owners of these assets could adversely affect our ability to respond to changing economic or industry conditions, which could have a material adverse effect on our business, results of operations, financial condition and ability to make payments on the notes.

 

The Partially Owned Entities may reduce their cash distributions to us in some situations.

 

The Partially Owned Entities’ organizational documents require distribution of their available cash to their members on a quarterly basis. In each case, available cash is reduced, in part, by reserves appropriate for operating their respective businesses.

Significant prolonged changes in natural gas prices could affect supply and demand, cause a reduction in or termination of the long-term transportation and storage contracts or throughput on the Pipeline Entities’ systems, and adversely affect our cash available to make distributions.

 

Higher natural gas prices over the long term could result in a decline in the demand for natural gas and, therefore, in the Pipeline Entities’ long-term transportation and storage contracts or throughput on their respective systems. Also, lower natural gas prices over the long term could result in a decline in the production of natural gas resulting in reduced contracts or throughput on their systems. As a result, significant prolonged changes in natural gas prices could have a material adverse effect on our Pipeline Entities’ business, financial condition, results of operations and cash flows, and on our ability to pay interest on, and the principal of, the notes.

 

The Pipeline Entities’ natural gas sales, transportation and storage operations are subject to regulation by FERC, which could have an adverse impact on their ability to establish transportation and storage rates that would allow them to recover the full cost of operating their respective pipelines, including a reasonable rate of return.

 

The Pipeline Entities’ natural gas sales, transmission and storage operations are subject to federal, state and local regulatory authorities. Specifically, their interstate pipeline transportation and storage service is subject to regulation by FERC. The federal regulation extends to such matters as:

 

 

Under the Natural Gas Act (“NGA”), FERC has authority to regulate providers of natural gas pipeline transportation and storage services in interstate commerce, and such providers may only charge rates that have been determined to be just and reasonable by FERC. In addition, FERC prohibits providers from unduly preferring or unreasonably discriminating against any person with respect to pipeline rates or terms and conditions of service.

 

Regulatory actions in these areas can affect our business in many ways, including decreasing tariff rates and revenues, decreasing volumes in our pipelines, increasing our costs and otherwise altering the profitability of our pipeline business.

 

The FERC Standards of Conduct govern the relationship between natural gas transmission providers and their marketing function employees as defined by the rule. The standards of conduct are intended to prevent natural gas transmission providers from preferentially benefiting gas marketing functions by requiring the employees of a transmission provider that perform transmission functions to function independently from marketing function employees and by restricting the information that transmission providers may provide to gas marketing employees. The inefficiencies created by the restrictions on the sharing of employees and information may increase our costs, and the restriction on the sharing of information may have an adverse impact on our senior management’s ability to effectively obtain important information about our business.

 

Unlike other pipelines that own facilities in the offshore Gulf of Mexico, Transco charges its transportation customers a separate fee to access its offshore facilities. The separate charge that it assesses, referred to as an “IT feeder” charge, is charged only when the facilities are used and typically is paid by producers or marketers. This

means that Transco recovers the costs included in the IT feeder charge only if its facilities are used, and because it is typically paid by producers and marketers, it generally results in netback prices to producers that are slightly lower than the netbacks realized by producers transporting on other interstate pipelines. Longer term, this rate design disparity could result in producers bypassing Transco’s offshore facilities in favor of alternative transportation facilities. Transco has asked FERC to allow it to eliminate the IT feeder charge and charge for transportation on its offshore facilities in the same manner as other pipelines. Transco’s requests have been denied.

 

The rates, terms and conditions for the Pipeline Entities’ interstate pipeline services are set forth in their respective FERC-approved tariffs. Any successful complaint or protest against the Pipeline Entities’ rates could have an adverse impact on their revenues associated with providing transportation services. In addition, there is a risk that rates set by FERC in future rate cases filed by the Pipeline Entities will be inadequate to recover increases in operating costs or to sustain an adequate return on capital investments. There is also the risk that higher rates would cause their customers to look for alternative ways to transport natural gas.

 

The Pipeline Entities could be subject to penalties and fines if they fail to comply with FERC regulations.

 

The Pipeline Entities’ transportation and storage operations are regulated by FERC. Should the Pipeline Entities fail to comply with all applicable FERC administered statutes, rules, regulations and orders, they could be subject to substantial penalties and fines. Under the Energy Policy Act of 2005, FERC has civil penalty authority under the NGA to impose penalties for current violations of up to $1,000,000 per day for each violation. Any material penalties or fines imposed by FERC could have a material adverse impact on the Pipeline Entities’ business, financial condition, results of operations and cash flows, and on our ability to pay interest on, and the principal of, the notes.

 

The outcome of certain FERC proceedings involving FERC policy statements is uncertain and could affect the level of return on equity that the Pipeline Entities may be able to achieve in any future rate proceeding.

 

In an effort to provide some guidance and to obtain further public comment on FERC’s policies concerning return on equity determinations, on July 19, 2007, FERC issued its Proposed Proxy Policy Statement, “Composition of Proxy Groups for Determining Gas and Oil Pipeline Return on Equity.” In the Proposed Proxy Policy Statement, FERC proposes to permit inclusion of publicly traded partnerships in the proxy group analysis relating to return on equity determinations in rate proceedings, provided that the analysis be limited to actual publicly traded partnership distributions capped at the level of the pipeline’s earnings.

 

After receiving public comment on the proposed policy statement, on April 17, 2008, FERC issued a final policy statement rejecting the concept of capping distributions in favor of an adjustment to the long-term growth rate used to calculate the equity cost of capital for publicly traded partnerships which are included in the proxy group.

 

On January 19, 2009, FERC applied the policy statement to a pipeline rate case and determined that the pipeline’s return on equity should be 11.55 percent. It is difficult to know how instructive this case is for purposes of anticipating rates of return in future rate cases, because FERC determined the composition of the proxy group using data from 2004 when the case was filed.

 

The effect of the application of FERC’s policy to the Pipeline Entities’ future rate proceedings is not certain, and we cannot ensure that such application would not adversely affect our ability to achieve a reasonable level of return on equity.

 

The outcome of future rate cases to set the rates the Pipeline Entities can charge customers on their respective pipelines might result in rates that lower their return on the capital invested in those pipelines.

 

There is a risk that rates set by FERC in the Pipeline Entities’ future rate cases will be inadequate to recover increases in operating costs or to sustain an adequate return on capital investments. There is also the risk that higher rates will cause their customers to look for alternative ways to transport their natural gas.

The outcome of future rate cases will determine the amount of income taxes the Pipeline Entities will be allowed to recover.

 

In May 2005, FERC issued a statement of general policy permitting a pipeline to include in its cost-of-service computations an income tax allowance provided that an entity or individual has an actual or potential income tax liability on income from the pipeline’s public utility assets. The extent to which owners of pipelines have such actual or potential income tax liability will be reviewed by FERC on a case-by-case basis in rate cases where the amounts of the allowances will be established.

 

Legal and regulatory proceedings and investigations relating to the energy industry and capital markets have adversely affected the Pipeline Entities’ businesses and may continue to do so.

 

Public and regulatory scrutiny of the energy industry and of the capital markets has resulted in increased regulation being either proposed or implemented. Such scrutiny has also resulted in various inquiries, investigations and court proceedings in which the Pipeline Entities’ or their affiliates are named as defendants. Both the shippers on the Pipeline Entities’ pipelines and regulators have rights to challenge the rates they charge under certain circumstances. Any successful challenge could materially affect the Pipeline Entities’ results of operations.

 

Certain inquiries, investigations and court proceedings are ongoing. Adverse effects may continue as a result of the uncertainty of these ongoing inquiries and proceedings, or additional inquiries and proceedings by federal or state regulatory agencies or private plaintiffs. In addition, we cannot predict the outcome of any of these inquiries or whether these inquiries will lead to additional legal proceedings against the Pipeline Entities, civil or criminal fines or penalties, or other regulatory action, including legislation, which might be materially adverse to the operation of the Pipeline Entities’ businesses and our revenues and net income or increase their operating costs in other ways. Current legal proceedings or other matters against us including environmental matters, suits, regulatory appeals and similar matters might result in adverse decisions against the Pipeline Entities. The result of such adverse decisions, either individually or in the aggregate, could be material and may not be covered fully or at all by insurance.

 

Increased competition from alternative natural gas transportation and storage options and alternative fuel sources could have a significant financial impact on us.

 

We compete primarily with other interstate pipelines and storage facilities in the transportation and storage of natural gas. Some of our competitors may have greater financial resources and access to greater supplies of natural gas than we do. Some of these competitors may expand or construct transportation and storage systems that would create additional competition for natural gas supplies or the services we provide to our customers. Moreover, Williams and its other affiliates may not be limited in their ability to compete with us. Further, natural gas also competes with other forms of energy available to our customers, including electricity, coal, fuel oils and other alternative energy sources.

 

The principal elements of competition among natural gas transportation and storage assets are rates, terms of service, access to natural gas supplies, flexibility and reliability. FERC’s policies promoting competition in natural gas markets are having the effect of increasing the natural gas transportation and storage options for our traditional customer base. As a result, we could experience some “turnback” of firm capacity as the primary terms of existing agreements expire. If we are unable to remarket this capacity or can remarket it only at substantially discounted rates compared to previous contracts, we or our remaining customers may have to bear the costs associated with the turned back capacity. Increased competition could reduce the amount of transportation or storage capacity contracted on our system or, in cases where we do not have long-term fixed rate contracts, could force us to lower our transportation or storage rates. Competition could intensify the negative impact of factors that significantly decrease demand for natural gas or increase the price of natural gas in the markets served by our pipeline system, such as competing or alternative forms of energy, a regional or national recession or other adverse economic conditions, weather, higher fuel costs and taxes or other governmental or regulatory actions that directly or indirectly increase the price of natural gas or limit the use of natural gas. Our ability to renew or replace existing contracts at rates sufficient to maintain current revenues and cash flows could be adversely affected by the activities of our competitors. All of these competitive pressures could have a material adverse effect on our business, financial condition, results of operations and cash flows and our ability to pay interest on, and the principal of, the notes.

We may not be able to maintain or replace expiring natural gas transportation and storage contracts at favorable rates or on a long-term basis.

 

The Pipeline Entities’ primary exposure to market risk occurs at the time the terms of existing transportation and storage contracts expire and are subject to termination. Although none of our material contracts are terminable in 2010, upon expiration of the terms we may not be able to extend contracts with existing customers to obtain replacement contracts at favorable rates or on a long-term basis.

 

The extension or replacement of existing contracts depends on a number of factors beyond our control, including:

 

 

Any failure to extend or replace a significant portion of our existing contracts may have a material adverse effect on our business, financial condition, results of operations and cash flows and our ability to pay interest on, and the principal of, the notes.

 

Competitive pressures could lead to decreases in the volume of natural gas contracted or transported through the Pipeline Entities’ pipeline systems.

 

Although most of the Pipeline Entities’ pipeline systems’ current capacity is fully contracted, FERC has taken certain actions to strengthen market forces in the natural gas pipeline industry that have led to increased competition throughout the industry. In a number of key markets, interstate pipelines are now facing competitive pressure from other major pipeline systems, enabling local distribution companies and end users to choose a transmission provider based on considerations other than location. Other entities could construct new pipelines or expand existing pipelines that could potentially serve the same markets as our pipeline system. Any such new pipelines could offer transportation services that are more desirable to shippers because of locations, facilities, or other factors. These new pipelines could charge rates or provide service to locations that would result in greater net profit for shippers and producers and thereby force us to lower the rates charged for service on our pipeline in order to extend our existing transportation service agreements or to attract new customers. We are aware of proposals by competitors to expand pipeline capacity in certain markets we also serve which, if the proposed projects proceed, could increase the competitive pressure upon us. There can be no assurance that we will be able to compete successfully against current and future competitors and any failure to do so could have a material adverse effect on our business, results of operations, and our ability to pay interest on, and the principal of, the notes.

 

Decreases in demand for natural gas could adversely affect our business.

 

Demand for our transportation services depends on the ability and willingness of shippers with access to our facilities to satisfy their demand by deliveries through our system. Any decrease in this demand could adversely affect our business. Demand for natural gas is also affected by weather, future industrial and economic conditions, fuel conservation measures, alternative fuel requirements, governmental regulation, or technological advances in fuel economy and energy generation devices, all of which are matters beyond our control. Additionally, in some cases, new LNG import facilities built near our markets could result in less demand for our gathering and transmission facilities.

The failure of new sources of natural gas production or LNG import terminals to be successfully developed in North America could increase natural gas prices and reduce the demand for our services.

 

New sources of natural gas production in the United States and Canada, particularly in areas of shale development, are expected to become an increasingly significant component of future U.S. natural gas supply in North America. Additionally, increases in LNG supplies are expected to be imported through new LNG import terminals, particularly in the Gulf Coast region. If these additional sources of supply are not developed, natural gas prices could increase and cause consumers of natural gas to turn to alternative energy sources, which could have a material adverse effect on our business, financial condition, results of operations and cash flows and our ability to pay interest on, and the principal of, the notes.

 

Certain of the Pipeline Entities’ services are subject to long-term, fixed-price contracts that are not subject to adjustment, even if our cost to perform such services exceeds the revenues received from such contracts.

 

The Pipeline Entities provide some services pursuant to long-term, fixed price contracts. It is possible that costs to perform services under such contracts will exceed the revenues they collect for their services. Although most of the services are priced at cost-based rates that are subject to adjustment in rate cases, under FERC policy, a regulated service provider and a customer may mutually agree to sign a contract for service at a “negotiated rate” that may be above or below the FERC-regulated, cost-based rate for that service. These “negotiated rate” contracts are not generally subject to adjustment for increased costs that could be produced by inflation or other factors relating to the specific facilities being used to perform the services.

 

Our operations are subject to operational hazards and unforeseen interruptions for which they may not be adequately insured.

 

There are operational risks associated with the gathering, transporting, storage, processing and treating of natural gas and the fractionation and storage of NGLs, including:

 

 

Any of these risks could result in loss of human life, personal injuries, significant damage to property, environmental pollution, impairment of our operations and substantial losses to us. In accordance with customary industry practice, we maintain insurance against some, but not all, of these risks and losses, and only at levels we believe to be appropriate. The location of certain segments of our facilities in or near populated areas, including residential areas, commercial business centers and industrial sites, could increase the level of damages resulting from these risks. In spite of our precautions, an event such as those described above could cause considerable harm to people or property, and could have a material adverse effect on our financial condition and results of operations,

particularly if the event is not fully covered by insurance. Accidents or other operating risks could further result in loss of service available to our customers.

 

Some portions of our current pipeline infrastructure and other assets have been in use for many decades, which may adversely affect our business.

 

Some portions of our assets, including our pipeline infrastructure, have been in use for many decades. The current age and condition of our assets could result in a material adverse impact on our business, financial condition and results of operations if the costs of maintaining our facilities exceed current expectations.

 

Our operations are subject to governmental laws and regulations relating to the protection of the environment, which may expose us to significant costs and liabilities and could exceed current expectations.

 

The risk of substantial environmental costs and liabilities is inherent in natural gas gathering, transportation, storage, processing and treating, and in the fractionation and storage of NGLs, and we may incur substantial environmental costs and liabilities in the performance of these types of operations. Our operations are subject to extensive federal, state and local environmental laws and regulations governing environmental protection, the discharge of materials into the environment and the security of chemical and industrial facilities. These laws include:

 

 

Various governmental authorities, including the United States Environmental Protection Agency (“EPA”) and analogous state agencies and the United States Department of Homeland Security, have the power to enforce compliance with these laws and regulations and the permits issued under them, oftentimes requiring difficult and costly actions. Failure to comply with these laws, regulations, and permits may result in the assessment of administrative, civil, and criminal penalties, the imposition of remedial obligations, the imposition of stricter conditions on or revocation of permits, and the issuance of injunctions limiting or preventing some or all of our operations.

 

There is inherent risk of the incurrence of environmental costs and liabilities in our business, some of which may be material, due to our handling of the products we gather, transport, process, fractionate and store, air emissions related to our operations, historical industry operations, waste disposal practices, and the prior use of flow meters containing mercury. Joint and several, strict liability may be incurred without regard to fault under certain environmental laws and regulations, including CERCLA, RCRA, and analogous state laws, for the remediation of contaminated areas and in connection with spills or releases of natural gas and wastes on, under, or from our properties and facilities. Private parties, including the owners of properties through which our pipeline and gathering systems pass and facilities where our wastes are taken for reclamation or disposal, may have the right to pursue legal actions to enforce compliance as well as to seek damages for non-compliance with environmental laws and regulations or for personal injury or property damage arising from our operations. Some sites we operate are located near current or former third-party hydrocarbon storage and processing operations, and there is a risk that contamination has migrated from those sites to ours. In addition, increasingly strict laws, regulations and enforcement policies could materially increase our compliance costs and the cost of any remediation that may become necessary. Our insurance may not cover all environmental risks and costs or may not provide sufficient coverage if an environmental claim is made against us.

Our business may be adversely affected by increased costs due to stricter pollution control requirements or liabilities resulting from non-compliance with required operating or other regulatory permits. Also, we might not be able to obtain or maintain from time to time all required environmental regulatory approvals for our operations. If there is a delay in obtaining any required environmental regulatory approvals, or if we fail to obtain and comply with them, the operation of our facilities could be prevented or become subject to additional costs, resulting in potentially material adverse consequences to our business, financial condition, results of operations and cash flows.

 

In addition, recent scientific studies have suggested that emissions of certain gases, commonly referred to as greenhouse gases (“GHGs”), may be contributing to warming of the earth’s atmosphere, and various governmental bodies have considered legislative and regulatory responses in this area.

 

Legislative and regulatory responses related to GHGs and climate change creates the potential for financial risk. The United States Congress and certain states have for some time been considering various forms of legislation related to GHG emissions. There have also been international efforts seeking legally binding reductions in emissions of GHGs. In addition, increased public awareness and concern may result in more state, regional and/or federal requirements to reduce or mitigate GHG emissions.

 

Several bills have been introduced in the United States Congress that would compel GHG emission reductions. On June 26, 2009, the U.S. House of Representatives passed the “American Clean Energy and Security Act” which is intended to decrease annual GHG emissions through a variety of measures, including a “cap and trade” system which limits the amount of GHGs that may be emitted and incentives to reduce the nation’s dependence on traditional energy sources. The U.S. Senate is currently considering similar legislation, and numerous states have also announced or adopted programs to stabilize and reduce GHGs. In addition, on December 7, 2009, the EPA issued a final determination that six GHGs are a threat to public safety and welfare. This determination could ultimately lead to the direct regulation of GHG emissions in our industry under the CAA. While it is not clear whether or when any federal or state climate change laws or regulations will be passed, any of these actions could result in increased costs to (i) operate and maintain our facilities, (ii) install new emission controls on our facilities, and (iii) administer and manage any GHG emissions program. If we are unable to recover or pass through a significant level of our costs related to complying with climate change regulatory requirements imposed on us, it could have a material adverse effect on our results of operations and our ability to pay interest on, and the principal of, the notes. To the extent financial markets view climate change and GHG emissions as a financial risk, this could negatively impact our cost of and access to capital.

 

Certain environmental and other groups have suggested that additional laws and regulations may be needed to more closely regulate the hydraulic fracturing process commonly used in natural gas production and legislation has been proposed in Congress to provide for such regulation. We cannot predict whether any federal, state or local legislation or regulation will be enacted in this area and if so, what its provisions would be. If additional levels of reporting, regulation and permitting were required, our operations and those of our customers could be adversely affected.

 

We make assumptions and develop expectations about possible expenditures related to environmental conditions based on current laws and regulations and current interpretations of those laws and regulations. If the interpretation of laws or regulations, or the laws and regulations themselves, change, our assumptions may change, and any new capital costs incurred to comply with such changes may not be recoverable under our regulatory rate structure or our customer contracts. In addition, new environmental laws and regulations might adversely affect our products and activities, including processing, fractionation, storage and transportation, as well as waste management and air emissions. For instance, federal and state agencies could impose additional safety requirements, any of which could affect our profitability.

 

We do not insure against all potential losses and could be seriously harmed by unexpected liabilities or by the ability of the insurers we do use to satisfy our claims.

 

We are not fully insured against all risks inherent to our business, including environmental accidents that might occur. In addition, we do not maintain business interruption insurance in the type and amount to cover all possible risks of loss. We currently maintain excess liability insurance with limits of $610 million per occurrence and in the aggregate annually and a deductible of $2 million per occurrence. This insurance covers us, our subsidiaries, and

certain of our affiliates for legal and contractual liabilities arising out of bodily injury, personal injury or property damage, including resulting loss of use to third parties. This excess liability insurance includes coverage for sudden and accidental pollution liability for full limits, with the first $135 million of insurance also providing gradual pollution liability coverage for natural gas and NGL operations. Pollution liability coverage excludes: release of pollutants subsequent to their disposal; release of substances arising from the combustion of fuels that result in acidic deposition; and testing, monitoring, clean-up, containment, treatment or removal of pollutants from property owned, occupied by, rented to, used by or in the care, custody or control of us, our subsidiaries, or certain of our affiliates.

 

We do not insure onshore underground pipelines for physical damage, except at river crossings and at certain locations such as compressor stations. We maintain coverage of $300 million per occurrence for physical damage to onshore assets and resulting business interruption caused by terrorist acts. We also maintain coverage of $100 million per occurrence for physical damage to offshore assets caused by terrorist acts, except for our Devils Tower spar where we maintain limits of $450 million per occurrence for physical damage caused by terrorist acts. We purchase insurance for business interruption arising from physical loss or damage resulting from terrorist acts only for certain offshore assets. Also, all of our insurance is subject to deductibles. If a significant accident or event occurs for which we are not fully insured, it could adversely affect our operations and financial condition. We may not be able to maintain or obtain insurance of the type and amount we desire at reasonable rates. Changes in the insurance markets subsequent to hurricanes losses in recent years have impacted named windstorm insurance coverage, rates and availability for Gulf of Mexico area exposures, and we may elect to self insure a portion of our asset portfolio. We cannot assure you that we will in the future be able to obtain the levels or types of insurance we would otherwise have obtained prior to these market changes or that the insurance coverage we do obtain will not contain large deductibles or fail to cover certain hazards or cover all potential losses. The occurrence of any operating risks not fully covered by insurance could have a material adverse effect on our business, financial condition, results of operations and cash flows, and our ability to pay interest on, and the principal of, the notes.

 

In addition, certain insurance companies that provide coverage to us, including American International Group, Inc., have experienced negative developments that could impair their ability to pay any of our potential claims. As a result, we could be exposed to greater losses than anticipated and may have to obtain replacement insurance, if available, at a greater cost.

 

Execution of our capital projects subjects us to construction risks, increases in labor costs and materials, and other risks that may adversely affect financial results.

 

Our growth may be dependent upon the construction of new natural gas gathering, transportation, processing or treating pipelines and facilities or NGL fractionation or storage facilities, as well as the expansion of existing facilities. Construction or expansion of these facilities is subject to various regulatory, development and operational risks, including:

 

 

Any of these risks could prevent a project from proceeding, delay its completion or increase its anticipated costs. As a result, new facilities may not achieve expected investment return, which could adversely affect our

results of operations, financial position, or cash flows and our ability to pay interest on, and the principal of, the notes.

 

Our operating results for certain segments of our business might fluctuate on a seasonal and quarterly basis.

 

Revenues from certain segments of our business can have seasonal characteristics. In many parts of the country, demand for natural gas and other fuels peaks during the winter. As a result, our overall operating results in the future might fluctuate substantially on a seasonal basis. Demand for natural gas and other fuels could vary significantly from our expectations depending on the nature and location of our facilities and pipeline systems and the terms of our natural gas transportation arrangements relative to demand created by unusual weather patterns.

 

We do not operate all of our assets. This reliance on others to operate our assets and to provide other services could adversely affect our business and operating results.

 

Williams and other third parties operate certain of our assets. We have a limited ability to control these operations and the associated costs. The success of these operations is therefore dependent upon a number of factors that are outside our control, including the competence and financial resources of the operators.

 

We rely on Williams for certain services necessary for us to be able to conduct our business. Williams may outsource some or all of these services to third parties, and a failure of all or part of Williams’ relationships with its outsourcing providers could lead to delays in or interruptions of these services. Our reliance on Williams and others as operators and on Williams’ outsourcing relationships, and our limited ability to control certain costs could have a material adverse effect on our business, results of operations, and financial condition and our ability to pay interest on, and the principal of, the notes.

 

We do not own all of the land on which our pipelines and facilities are located, which could disrupt our operations.

 

We do not own all of the land on which our pipelines and facilities have been constructed. As such, we are subject to the possibility of increased costs to retain necessary land use. We obtain the rights to construct and operate our pipelines and gathering systems on land owned by third parties and governmental agencies for a specific period of time. Our loss of these rights, through our inability to renew right-of-way contracts or otherwise, could have a material adverse effect on our business, results of operations, and financial condition and our ability to pay interest on, and the principal of, the notes.

 

Potential changes in accounting standards might cause us to revise our financial results and disclosures in the future, which might change the way analysts measure our business or financial performance.

 

Regulators and legislators continue to take a renewed look at accounting practices, financial disclosures, retirement plan practices and companies’ relationships with their independent public accounting firms. It remains unclear what new laws or regulations will be adopted, and we cannot predict the ultimate impact that any such new laws or regulations could have. In addition, the Financial Accounting Standards Board, the SEC or FERC could enact new accounting standards or FERC orders that might impact how we are required to record revenues, expenses, assets and liabilities. Any significant change in accounting standards or disclosure requirements could have a material adverse effect on our business, results of operations, and financial condition and our ability to pay interest on, and the principal of, the notes.

 

Institutional knowledge residing with current employees nearing retirement eligibility might not be adequately preserved.

 

In our business, institutional knowledge resides with employees who have many years of service. As these employees reach retirement age, we may not be able to replace them with employees of comparable knowledge and experience. In addition, we may not be able to retain or recruit other qualified individuals, and our efforts at knowledge transfer could be inadequate. If knowledge transfer, recruiting and retention efforts are inadequate, access to significant amounts of internal historical knowledge and expertise could become unavailable to us.

Failure of or disruptions to our outsourcing relationships might negatively impact our ability to conduct our business.

 

Some studies indicate a high failure rate of outsourcing relationships. Although Williams has taken steps to build a cooperative and mutually beneficial relationship with its outsourcing providers and to closely monitor their performance, a deterioration in the timeliness or quality of the services performed by the outsourcing providers or a failure of all or part of these relationships could lead to loss of institutional knowledge and interruption of services necessary for us to be able to conduct our business. The expiration of such agreements or the transition of services between providers could lead to similar losses of institutional knowledge or disruptions.

 

Certain of our accounting, information technology, application development, and help desk services are currently provided by Williams’ outsourcing provider from service centers outside of the United States. The economic and political conditions in certain countries from which Williams’ outsourcing providers may provide services to us present similar risks of business operations located outside of the United States, including risks of interruption of business, war, expropriation, nationalization, renegotiation, trade sanctions or nullification of existing contracts and changes in law or tax policy, that are greater than in the United States.

 

Acts of terrorism could have a material adverse effect on our financial condition, results of operations and cash flows.

 

Our assets and the assets of our customers and others may be targets of terrorist activities that could disrupt our business or cause significant harm to our operations, such as full or partial disruption to our ability to produce, process, transport or distribute natural gas, NGLs or other commodities. Acts of terrorism as well as events occurring in response to or in connection with acts of terrorism could cause environmental repercussions that could result in a significant decrease in revenues or significant reconstruction or remediation costs, which could have a material adverse effect on our financial condition, results of operations, and cash flows and on our ability to pay interest on, and the principal of, the notes.

 

We may not realize the anticipated benefits from the Dropdown.

 

We may not realize the benefits that we anticipate from the Dropdown for a number of reasons, including, but not limited to, if any of the matters identified as risks in the Risk Factors section in this prospectus supplement were to occur. If we do not realize the anticipated benefits from the Dropdown for any reason, our business may be materially adversely affected.

 

Risks Related to our Relationship with Williams

 

Williams controls our general partner, which has sole responsibility for conducting our business and managing our operations. Our general partner has limited fiduciary duties to, and it and its affiliates may have conflicts of interest with, us and our unitholders, and our general partner and its affiliates may favor their interests to the detriment of our unitholders.

 

Williams owns and controls our general partner and appoints all of the directors of our general partner. All of the executive officers and certain directors of our general partner are officers and/or directors of Williams and certain of its affiliates. Although our general partner has a fiduciary duty to manage us in a manner beneficial to us, the directors and officers of our general partner also have a fiduciary duty to manage our general partner in a manner beneficial to Williams. Therefore, conflicts of interest may arise between Williams and its affiliates, including our general partner, on the one hand, and us and our unitholders, on the other hand. In resolving these conflicts, our general partner may favor its own interests and the interests of its affiliates over the interests of our unitholders. These conflicts include, among others, the following factors:

 

 

 

Affiliates of our general partner, including Williams, are not limited in their ability to compete with us. Williams is also not obligated to offer us the opportunity to acquire additional assets or businesses from it, which could limit our commercial activities or our ability to grow. In addition, all of the executive officers and certain of the directors of our general partner are also officers and/or directors of Williams, and these persons will also owe fiduciary duties to it.

 

While our relationship with Williams and its affiliates is a significant attribute, it is also a source of potential conflicts. For example, Williams is in the natural gas business and is not restricted from competing with us.

Williams and its affiliates may compete with us. Williams and its affiliates may acquire, construct or dispose of natural gas industry assets in the future, some or all of which may compete with our assets, without any obligation to offer us the opportunity to purchase or construct such assets. In addition, all of the executive officers and certain of the directors of our general partner are also officers and/or directors of Williams and certain of its affiliates and will owe fiduciary duties to those entities as well as our unitholders and us.

 

Our allocation from Williams for costs for its defined benefit pension plans and other postretirement benefit plans are affected by factors beyond our and Williams’ control.

 

As we have no employees, employees of Williams and its affiliates provide services to us. As a result, we are allocated a portion of Williams’ costs in defined benefit pension plans covering substantially all of Williams’ or its affiliates’ employees providing services to us, as well as a portion of the costs of other postretirement benefit plans covering certain eligible participants providing services to us. The timing and amount of our allocations under the defined benefit pension plans depend upon a number of factors Williams controls, including changes to pension plan benefits, as well as factors outside of Williams’ control, such as asset returns, interest rates and changes in pension laws. Changes to these and other factors that can significantly increase our allocations could have a significant adverse effect on our financial condition and results of operations.

 

The net proceeds from this offering of notes will be approximately $      million after deducting the estimated underwriting discount and commissions. We intend to use the net proceeds of this offering to fund a portion of the cash consideration to be paid in the Midstream Piceance Acquisition.

 

The following table sets forth our consolidated ratio of earnings to fixed charges for each of the periods indicated, revised to reflect the consummation of the Dropdown.

 

 

 

 

The following table sets forth our historical cash and cash equivalents and capitalization as of September 30, 2010 and our pro forma cash and cash equivalents and capitalization as of September 30, 2010, as adjusted to reflect:

 

 

This table is derived from and should be read together with our historical consolidated financial statements and the accompanying notes included in our Third Quarter 2010 10-Q, which is incorporated by reference in this prospectus supplement. You should also read this table in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Third Quarter 2010 10-Q, which is incorporated by reference into this prospectus supplement.

 

 

We will issue $     in aggregate principal amount of senior notes due           under an indenture (the “base indenture”) between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “trustee”), as amended and supplemented by a supplemental indenture (the “supplemental indenture”) between the Company and the trustee relating to the issuance of the notes. The base indenture, as amended and supplemented by the supplemental indenture, is referred to herein as the “indenture.” The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

 

The following description of certain terms of the notes supplements, and to the extent inconsistent, replaces, the description under “Description of the Debt Securities” in the accompanying prospectus. The following description and the description under “Description of the Debt Securities” in the accompanying prospectus together constitute a summary of the material provisions of the indenture and the notes. They do not restate those documents in their entirety. We urge you to read the indenture in its entirety, because it, and not this description or the description under “Description of the Debt Securities” in the accompanying prospectus, defines your rights as holders of the notes. Copies of the indenture are available as set forth below under “— Additional Information.” You can find the definitions of certain terms used in this description under the subheading “— Certain Definitions.” In this description, the term “Company,” “us,” “our” or “we” refers only to Williams Partners L.P. and not to any of our subsidiaries. Certain defined terms used in this “Description of the Notes” but not defined below under “— Certain Definitions” have the meanings assigned to them in the indenture.

 

The registered holder of a note will be treated as the owner of it for all purposes. Only registered holders will have rights under the indenture.

 

Brief Description of the Notes

 

The notes:

 

 

Assuming that we had completed this offering of the notes on September 30, 2010:

 

 

The indenture will permit us to incur additional indebtedness, including additional senior unsecured indebtedness. The indenture also will not restrict the ability of our subsidiaries to incur additional indebtedness. See “Risks Related to the Notes — Our indebtedness could impair our financial condition and our ability to fulfill our debt obligations, including our obligations under the notes.”

 

We own a noncontrolling interest in Aux Sable Liquid Products Inc., Aux Sable Liquid Products LP, Baton Rouge Fractionators LLC, Baton Rouge Pipeline LLC, Cardinal Pipeline Company LLC, Discovery Producer Services LLC, Gulfstream Natural Gas System, L.L.C., Laurel Mountain Midstream Ohio, LLC, Laurel Mountain Midstream Operating LLC, Laurel Mountain Midstream, LLC, Overland Pass Pipeline Company LLC, Pine Needle LNG Company, LLC, Pacific Connector Gas Pipeline, LLC, Pacific Connector Gas Pipeline, LP. We use the equity method of accounting for these investments and they will not be classified as Subsidiaries of ours under the indenture so long as we continue to own a noncontrolling interest in each of them. As a result, the entities listed above will not be subject to the restrictive covenants in the indenture so long as they are not a Subsidiaries of ours.

Principal, Maturity and Interest

 

We will issue the notes with an initial maximum aggregate principal amount of $          . The notes will mature on          . We will issue notes in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

 

Interest on the notes will accrue at the rate of     % per annum, and will be payable semi-annually in arrears on          and          , beginning on          . We will make each interest payment on the notes to the holders of record at the close of business on the immediately preceding          or          (whether or not a Business Day).

 

Interest on the notes will accrue from the date of original issuance or, if interest has already been paid or duly provided for, from the date it was most recently paid or duly provided for. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months.

 

We may, without the consent of the holders of notes, issue additional notes having the same ranking and the same interest rate, maturity and other terms as the notes, except that interest would accrue from the date of issuance of such additional notes and such additional notes may not be fungible for trading purposes with, and may initially bear a different identifying numbers than, the notes offered hereby. Any additional notes having such similar terms, together with the notes offered hereby, will constitute a single series of debt securities under the indenture.

 

Methods of Receiving Payments on the Notes

 

We will pay all principal, interest and premium, if any, on the notes in the manner described under “— Same-Day Settlement and Payment” below.

 

Paying Agent and Registrar for the Notes

 

The trustee will initially act as paying agent and registrar. We may change the paying agent or registrar without prior notice to the holders of the notes, and we or any of our Subsidiaries may act as paying agent or registrar.

 

Transfer and Exchange

 

A holder may transfer or exchange notes in accordance with the indenture. The registrar and the trustee may require a holder to furnish appropriate endorsements and transfer documents in connection with a transfer of notes. No service charges will be imposed by us, the trustee or the registrar for any registration of transfer or exchange of notes, but holders may be required to pay all taxes due on transfer or exchange. We are not required to transfer or exchange any note selected for redemption. Also, we are not required to transfer or exchange any note for a period of 15 days before mailing notice of any redemption of notes.

 

Optional Redemption

 

We may, at our option, redeem the notes, in whole or in part, at any time or from time to time at a redemption price equal to the greater of:

 

(1) 100% of the principal amount of the notes to be redeemed, plus accrued interest to the redemption date, and

 

(2) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal of and interest on the notes to be redeemed (not including any portion of payments of interest accrued as of the redemption date) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus           basis points, plus accrued interest to the redemption date.

 

We also have the option, at any time on or after                     (which is the date that is three months prior to the maturity date of the notes), to redeem the notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest thereon to the redemption date.

Selection and Notice

 

If less than all of the notes are to be redeemed at any time, the trustee will select such notes for redemption from the outstanding notes not previously called for redemption on a pro rata basis or by lot (whichever is consistent with the trustee’s customary practice).

 

No notes of $2,000 or less can be redeemed in part. Notices of optional redemption will be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each holder of notes to be redeemed at its registered address. Notices of redemption may not be conditional.

 

If any note is to be redeemed in part only, the notice of redemption that relates to that note will state the portion of the principal amount of that note that is to be redeemed. A new note in principal amount equal to the unredeemed portion of the original note will be issued in the name of the holder of notes upon cancellation of the original note. Notes called for redemption become due on the date fixed for redemption. On and after the redemption date, interest will cease to accrue on notes or portions of them called for redemption.

 

Mandatory Redemption

 

We are not required to make mandatory redemption or sinking fund payments with respect to the notes or to repurchase the notes at the option of the holders.

 

Certain Covenants

 

Except as set forth in this “Description of the Notes,” neither we nor any of our Subsidiaries will be restricted by the indenture from incurring additional indebtedness or other obligations, from making distributions or paying dividends on our or our Subsidiaries’ equity interests or from purchasing our or our Subsidiaries’ equity interests. The indenture does not require the maintenance of any financial ratios or specified levels of net worth or liquidity. In addition, the indenture does not contain any provisions that would require us to repurchase or redeem any of the notes in situations that may adversely affect the creditworthiness of the notes.

 

Liens

 

We will not, and will not permit any Subsidiary of ours to, issue, assume or guarantee any Indebtedness secured by a Lien, other than Permitted Liens, upon any of our or any of our Subsidiaries’ property, now owned or hereafter acquired, unless the notes are equally and ratably secured with such Indebtedness until such time as such Indebtedness is no longer secured by a Lien.

 

Notwithstanding the preceding paragraph, we may, and may permit any Subsidiary of ours to, issue, assume or guarantee any Indebtedness secured by a Lien, other than a Permitted Lien, without securing the notes; provided that the aggregate principal amount of all Indebtedness of ours and any Subsidiary of ours then outstanding secured by any such Liens (other than Permitted Liens) does not exceed 15% of Consolidated Net Tangible Assets.

 

Merger, Consolidation or Sale of Assets

 

We may not directly or indirectly consolidate with or merge with or into, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of our assets and properties and the assets and properties of our Subsidiaries (taken as a whole) in one or more related transactions to another Person, unless:

 

(1) either: (a) we are the survivor; or (b) the Person formed by or surviving any such consolidation or merger (if other than us) or to which such sale, assignment, transfer, lease, conveyance or other disposition has been made is a Person formed, organized or existing under the laws of the United States, any state of the United States or the District of Columbia;

 

(2) the Person formed by or surviving any such consolidation or merger (if other than us) or the Person to which such sale, assignment, transfer, lease, conveyance or other disposition has been made expressly assumes by supplemental indenture, in form reasonably satisfactory to the trustee, executed by the successor person and delivered to the trustee, the due and punctual payment of the principal of and any premium and interest on the notes and the performance of all of our obligations under the indenture and the notes;

(3) we or the Person formed by or surviving any such merger will deliver to the trustee an officer’s certificate and an opinion of counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and such supplemental indenture (if any) comply with the indenture and that all conditions precedent in the indenture relating to such transaction have been complied with; and

 

(4) immediately after giving effect to such transaction, no Event of Default or event which, after notice or lapse of time, or both, would become an Event of Default, shall have occurred and be continuing.

 

Upon any consolidation by us with or our merger into any other Person or Persons where we are not the survivor or any sale, assignment, transfer, lease, conveyance or other disposition of all or substantially all of our properties and assets and the properties and assets of our Subsidiaries (taken as a whole) to any Person or Persons in accordance herewith, the successor Person formed by such consolidation or into which we are merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, us under the indenture with the same effect as if such successor Person had been named as the Company therein; and thereafter, except in the case of a lease, the predecessor Person shall be released from all obligations and covenants under the indenture and the notes.

 

Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve “all or substantially all” of the properties or assets of a Person.

 

Reports

 

We will:

 

(1) file with the trustee, within 30 days after we have filed the same with the Commission, unless such reports are available on the Commission’s EDGAR filing system (or any successor thereto), copies of the annual reports and of the information, documents, and other reports (or copies of such portions of any of the foregoing as the Commission may from time to time by rules and regulations prescribe) which we may be required to file with the Commission pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if we are not required to file information, documents or reports pursuant to either of said Sections, then we shall file with the trustee and the Commission, in accordance with rules and regulations prescribed from time to time by the Commission, such of the supplementary and periodic information, documents, and reports which may be required pursuant to Section 13 of the Exchange Act in respect of a security listed and registered on a national securities exchange as may be prescribed from time to time in such rules and regulations;

 

(2) file with the trustee and the Commission, in accordance with rules and regulations prescribed from time to time by the Commission, such additional information, documents and reports with respect to compliance by us with the conditions and covenants of the indenture as may be required from time to time by such rules and regulations; and

 

(3) transmit within 30 days after the filing thereof with the trustee, in the manner and to the extent provided in Section 313(c) of the Trust Indenture Act, such summaries of any information, documents and reports required to be filed by us pursuant to clauses (1) and (2) of this paragraph as may be required by rules and regulations prescribed from time to time by the Commission.

 

Events of Default and Remedies

 

Each of the following is an “Event of Default” with respect to the notes, and any references under “Description of the Debt Securities” in the accompanying prospectus to events of default described in the first paragraph under the heading “Events of Default” therein shall be deemed to be references to the following:

 

(a) default for 30 days in the payment when due of any interest on the notes;

 

(b) default in the payment of the principal of or any premium on the notes when the principal or premium becomes due and payable;

(c) failure by us duly to observe or perform any other of the covenants or agreements (other than those described in clause (a) or (b) above) in the indenture, which failure continues for a period of 60 days, or, in the case of the covenant set forth under “— Certain Covenants — Reports” above, which failure continues for a period of 90 days, after the date on which written notice of such failure, requiring the same to be remedied and stating that such notice is a “Notice of Default” has been given to us by the trustee, upon direction of holders of at least 25% in principal amount of then outstanding notes; provided, however, that if such failure is not capable of cure within such 60-day or 90-day period, as the case may be, such 60-day or 90-day period, as the case may be, shall be automatically extended by an additional 60 days so long as (i) such failure is subject to cure, and (ii) we are using commercially reasonable efforts to cure such failure; and provided, further, that a failure to comply with any such other agreement in the indenture that results from a change in GAAP shall not be deemed to be an Event of Default;

 

(d) certain events of bankruptcy, insolvency or reorganization described in the indenture with respect to us.

 

In case an Event of Default specified in clause (a) or (b) above shall occur and be continuing with respect to the notes, holders of at least 25%, and in case an Event of Default specified in clause (c) above shall occur and be continuing with respect to the notes, holders of at least a majority, in aggregate principal amount of the notes then outstanding may declare the principal to be due and payable. If an Event of Default described in clause (d) above shall occur and be continuing then the principal amount of all the debt securities then outstanding under the indenture shall be and become due and payable immediately, without notice or other action by any holder or the trustee, to the full extent permitted by law. Any past or existing default or Event of Default with respect to the notes may be waived by the holders of a majority in aggregate principal amount of the outstanding notes, except in each case a continuing default (1) in the payment of the principal of, any premium or interest on, or any additional amounts with respect to, any notes, or (2) in respect of a covenant or provision which cannot be modified or amended without the consent of each holder affected thereby.

 

The indenture provides that the trustee may withhold notice to the holders of any default with respect to the notes (except in payment of principal of or interest or premium on the notes) if the trustee considers it in the interest of holders to do so. The indenture contains a provision entitling the trustee to be indemnified by the holders before proceeding to exercise any trust or power under the indenture at the request of such holders. The indenture provides that the holders of a majority in aggregate principal amount of the then outstanding notes may direct the time, method and place of conducting any proceedings for any remedy available to the trustee or of exercising any trust or power conferred upon the trustee with respect to the notes; provided, however, that the trustee may decline to follow any such direction if, among other reasons, the trustee determines that the actions or proceedings as directed would be unduly prejudicial to the holders of the notes not joining in such direction. The right of a holder to institute a proceeding with respect to the notes will be subject to certain conditions precedent including, without limitation, that in case of an Event of Default specified in clause (a), (b) or (d) of the first paragraph above under “— Events of Default and Remedies,” holders of at least 25%, or in case of an Event of Default specified in clause (c) of the first paragraph above under “— Events of Default”, holders of at least a majority, in aggregate principal amount of the notes then outstanding make a written request upon the trustee to exercise its powers under the indenture, indemnify the trustee and afford the trustee reasonable opportunity to act.

 

Notwithstanding the foregoing, the holder has an absolute right to receipt of the principal of, premium, if any, and interest on and additional amounts with respect to the notes when due and to institute suit for the enforcement thereof. We are required to deliver to the trustee annually a statement regarding compliance with the indenture.

Book-Entry, Delivery and Form

 

Except as set forth below, notes will be issued in registered, global form, without interest coupons, which we refer to as “Global Notes.” Global Notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. Notes will be issued at the closing of this offering only against payment in immediately available funds.

 

The Global Notes will be deposited upon issuance with the trustee as custodian for The Depository Trust Company (“DTC”), in New York, New York, and registered in the name of DTC’s nominee, Cede & Co., in each case for credit to an account of a direct or indirect participant in DTC as described below.

 

Except as set forth below, the Global Notes may be transferred, in whole but not in part, only to DTC, to a nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the Global Notes may not be exchanged for notes in registered, certificated form (“Certificated Notes”) except in the limited circumstances described below. See “— Exchange of Certificated Notes for Global Notes.” Except in the limited circumstances described below, owners of beneficial interests in the Global Notes will not be entitled to receive physical delivery of notes in certificated form.

 

Transfers of beneficial interests in the Global Notes will be subject to the applicable rules and procedures of DTC and its direct or indirect participants (including, if applicable, those of the Euroclear System (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”)), which may change from time to time.

 

Depository Procedures

 

The following description of the operations and procedures of DTC is provided solely as a matter of convenience. These operations and procedures are solely within the control of DTC and are subject to changes by it. We take no responsibility for these operations and procedures and urge investors to contact DTC or its participants directly to discuss these matters.

 

DTC has advised us that DTC is a limited-purpose trust company created to hold securities for its participating organizations (collectively, the “Participants”) and to facilitate the clearance and settlement of transactions in those securities between Participants through electronic book-entry changes in accounts of its Participants. The Participants include securities brokers and dealers (including the underwriters), banks, trust companies, clearing corporations and certain other organizations. Access to DTC’s system is also available to other entities such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Participant, either directly or indirectly (collectively, the “Indirect Participants”). Persons who are not Participants may beneficially own securities held by or on behalf of DTC only through the Participants or the Indirect Participants. The ownership interests in, and transfers of ownership interests in, each security held by or on behalf of DTC are recorded on the records of the Participants and Indirect Participants.

 

DTC has also advised us that, pursuant to procedures established by it:

 

(1) upon deposit of the Global Notes, DTC will credit the accounts of the Participants designated by the underwriters with portions of the principal amount of the Global Notes; and

 

(2) ownership of these interests in the Global Notes will be shown on, and the transfer of ownership of these interests will be effected only through, records maintained by DTC (with respect to the Participants) or by the Participants and the Indirect Participants (with respect to other owners of beneficial interest in the Global Notes).

 

Investors in the Global Notes who are Participants may hold their interests therein directly through DTC. Investors in the Global Notes who are not Participants may hold their interests therein indirectly through organizations (including Euroclear and Clearstream) which are Participants. All interests in a Global Note, including those held through Euroclear or Clearstream, may be subject to the procedures and requirements of DTC. Those interests held through Euroclear or Clearstream may also be subject to the procedures and requirements of

such systems. The laws of some states require that certain Persons take physical delivery in definitive form of securities that they own. Consequently, the ability to transfer beneficial interests in a Global Note to such Persons will be limited to that extent. Because DTC can act only on behalf of the Participants, which in turn act on behalf of the Indirect Participants, the ability of a Person having beneficial interests in a Global Note to pledge such interests to Persons that do not participate in the DTC system, or otherwise take actions in respect of such interests, may be affected by the lack of a physical certificate evidencing such interests.

 

Except as described below, owners of an interest in the Global Notes will not have notes registered in their names, will not receive physical delivery of Certificated Notes and will not be considered the registered owners or “Holders” thereof under the indenture for any purpose.

 

Payments in respect of the principal of, and interest and premium, if any, on a Global Note registered in the name of DTC or its nominee will be payable to DTC in its capacity as the registered holder under the indenture. Under the terms of the indenture, the Company and the trustee will treat the Persons in whose names the notes, including the Global Notes, are registered as the owners of the notes for the purpose of receiving payments and for all other purposes. Consequently, neither the Company, the trustee nor any agent of ours or of the trustee has or will have any responsibility or liability for:

 

(1) any aspect of DTC’s records or any Participant’s or Indirect Participant’s records relating to, or payments made on account of, beneficial ownership interests in the Global Notes or for maintaining, supervising or reviewing any of DTC’s records or any Participant’s or Indirect Participant’s records relating to the beneficial ownership interests in the Global Notes; or

 

(2) any other matter relating to the actions and practices of DTC or any of its Participants or Indirect Participants.

 

DTC has advised us that its current practice, at the due date of any payment in respect of securities such as the notes, is to credit the accounts of the relevant Participants with the payment on the payment date unless DTC has reason to believe that it will not receive payment on such payment date. Each relevant Participant is credited with an amount proportionate to its beneficial ownership of an interest in the principal amount of the notes as shown on the records of DTC. Payments by the Participants and the Indirect Participants to the beneficial owners of notes will be governed by standing instructions and customary practices and will be the responsibility of the Participants or the Indirect Participants and will not be the responsibility of DTC, the trustee or us. Neither we nor the trustee will be liable for any delay by DTC or any of its Participants in identifying the beneficial owners of the notes, and the Company and the trustee may conclusively rely on and will be protected in relying on instructions from DTC or its nominee for all purposes.

 

Transfers between Participants in DTC will be effected in accordance with DTC’s procedures, and will be settled in same-day funds, and transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures.

 

Subject to compliance with the transfer restrictions applicable to the notes described herein, cross-market transfers between the Participants in DTC, on the one hand, and Euroclear or Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by its depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant Global Note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

 

DTC has advised us that it will take any action permitted to be taken by a holder of notes only at the direction of one or more Participants to whose account DTC has credited the interests in the Global Notes and only in respect of such portion of the aggregate principal amount of the notes as to which such Participant or Participants has or have

given such direction. However, if there is an Event of Default under the notes, DTC reserves the right to exchange the Global Notes for Certificated Notes, and to distribute such notes to its Participants.

 

Although DTC, Euroclear and Clearstream have agreed to the foregoing procedures to facilitate transfers of interests in the Global Notes among participants in DTC, Euroclear and Clearstream, they are under no obligation to perform or to continue to perform such procedures, and may discontinue such procedures at any time. Neither the Company nor the trustee nor any of their respective agents will have any responsibility for the performance by DTC, Euroclear or Clearstream or their respective Participants or Indirect Participants of their respective obligations under the rules and procedures governing their operations.

 

Exchange of Global Notes for Certificated Notes

 

A Global Note is exchangeable for Certificated Notes in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof if:

 

(1) DTC notifies us that it is unwilling or unable to continue as depositary for such Global Notes or that it has ceased to be a clearing agency registered under the Exchange Act and, in either case, we fail to appoint a successor depositary within 90 days after the date of such notice from DTC;

 

(2) we, at our option and subject to the procedures of DTC, notify the trustee in writing that we elect to cause the issuance of the Certificated Notes; or

 

(3) an Event of Default has occurred and is continuing with respect to the notes.

 

In all cases, Certificated Notes delivered in exchange for any Global Note or beneficial interests in Global Notes will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures).

 

Same-Day Settlement and Payment

 

We will make payments in respect of the notes represented by the Global Notes (including principal, interest and premium, if any) by wire transfer of immediately available funds to the accounts specified by the Global Note Holder. We will make all payments of principal, interest and premium, if any, with respect to Certificated Notes (i) to holders having an aggregate principal amount of $2,000,000 or less, by check mailed to such holder’s registered address or (ii) to holders having an aggregate principal amount of more than $2,000,000, by check mailed to such holder’s registered address or, upon application by a holder to the registrar not later than the relevant record date or in the case of payments of principal or premium, if any, not later than 15 days prior to the principal payment date, by wire transfer in immediately available funds to that holder’s account within the United States (subject to surrender of the Certificated Note in the case of payments of principal or premium), which application shall remain in effect until the holder notifies the registrar to the contrary in writing. The notes represented by the Global Notes are expected to be eligible to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such notes will, therefore, be required by DTC to be settled in immediately available funds. The Company expects that secondary trading in any Certificated Notes will also be settled in immediately available funds.

 

Because of time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in a Global Note from a Participant in DTC will be credited, and any such crediting will be reported to the relevant Euroclear or Clearstream participant, during the securities settlement processing day (which must be a business day for Euroclear and Clearstream) immediately following the settlement date of DTC. DTC has advised us that cash received in Euroclear or Clearstream as a result of sales of interests in a Global Note by or through a Euroclear or Clearstream participant to a Participant in DTC will be received with value on the settlement date of DTC but will be available in the relevant Euroclear or Clearstream cash account only as of the business day for Euroclear or Clearstream following DTC’s settlement date.

Williams Partners Notes

 

In connection with the Dropdown, we issued $3.5 billion aggregate principal face amount of senior unsecured notes consisting of $750 million of 3.800% senior notes due 2015, $1.5 billion of 5.250% senior notes due 2020 and $1.25 billion of 6.300% senior notes due 2040 (collectively, the “Dropdown Notes”). Additionally, as of September 30, 2010, we also had $150 million of 7.5% senior unsecured notes outstanding that mature on June 15, 2011 and $600 million of 7.25% senior unsecured notes outstanding that mature on February 1, 2017 (together, the “Existing Notes,” and collectively with the Dropdown Notes, the “Williams Partners Notes”).

 

The terms of the Williams Partners Notes are governed by indentures that contain covenants that, among other things, limit (1) our ability and the ability of our subsidiaries to incur liens on assets to secure certain debt and (2) certain mergers or consolidations and transfers of assets. The indentures also contain customary events of default, upon which the trustee or the holders of the Williams Partners Notes may declare all outstanding Williams Partners Notes to be due and payable immediately.

 

We may redeem the Williams Partners Notes at our option in whole or in part at any time or from time to time prior to the respective maturity dates, at the applicable redemption prices described in the indentures governing the Williams Partners Notes. We are not required to make mandatory redemption or sinking fund payments with respect to the Williams Partners Notes or to repurchase the Williams Partners Notes at the option of the holders.

 

Transco and Northwest Pipeline Notes

 

As of September 30, 2010, Transco had outstanding a total of $1,282,500,000 aggregate principal face amount of senior unsecured debt issues with various interest rates from 6.05% to 8.875% and maturities ranging from 2011 to 2026 (the “Transco Notes”). As of September 30, 2010, Northwest Pipeline had outstanding a total of $695,000,000 aggregate principal face amount of senior unsecured debt issues with various interest rates from 5.95% to 7.125% and maturities ranging from 2016 to 2025 (the “Northwest Pipeline Notes”).

 

The indentures governing the Transco Notes and the Northwest Pipeline Notes contain covenants that, among other things, limit Transco and Northwest Pipeline’s ability to (1) incur liens securing indebtedness, (2) engage in certain sale and lease-back transactions and (3) consolidate, merge, transfer or lease assets. The indentures also contain customary events of default including non-payment of principal or interest, failure to comply with covenants, and certain bankruptcy or insolvency events. Northwest Pipeline’s 7.125% Debentures due 2025 ($85 million aggregate principal amount outstanding as of September 30, 2010) are not subject to redemption prior to maturity. The remaining Northwest Pipeline Notes, and all of the Transco Notes, may be redeemed, in whole or in part, at any time and from time to time, as provided in the indentures governing the notes.

 

Credit Facility

 

In connection with the Dropdown, we entered into the Credit Facility with Transco and Northwest Pipeline, as co-borrowers, Citibank, N.A., as the administrative agent, and certain other named lenders. Under certain conditions, the Credit Facility may be increased by up to an additional $250 million. The full amount of the Credit Facility is available to us, to the extent not utilized by Transco or Northwest Pipeline. Each of Transco and Northwest Pipeline may borrow up to $400 million under the Credit Facility to the extent not otherwise utilized by us. As of September 30, 2010, no loans or letters of credit were outstanding under the Credit Facility.

 

Interest on borrowings under the Credit Facility is payable at rates per annum equal to, at the option of the borrower: (1) a fluctuating base rate equal to Citibank, N.A.’s adjusted base rate plus the applicable margin, or (2) a periodic fixed rate equal to LIBOR plus the applicable margin. The adjusted base rate will be the highest of (i) the federal funds rate plus 0.5 percent, (ii) Citibank N.A.’s publicly announced base rate, and (iii) one-month LIBOR plus 1.0 percent. We pay a commitment fee (currently 0.5 percent) on the unused portion of the facility. The applicable margin and the commitment fee are determined by reference to a pricing schedule based on the borrower’s senior unsecured debt ratings.

The Credit Facility contains various covenants that limit, among other things, a borrower’s and its respective subsidiaries’ ability to incur indebtedness, grant certain liens supporting indebtedness, merge or consolidate, sell all or substantially all of its assets, enter into certain affiliate transactions, make certain distributions during an event of default and allow any material change to the nature of its business.

 

In addition, we are required to maintain a ratio of debt to EBITDA (each as defined in the Credit Facility) of no greater than 5.00 to 1.00 for us and our consolidated subsidiaries. For each of Transco and Northwest Pipeline and their respective consolidated subsidiaries, the ratio of debt to capitalization (defined as net worth plus debt) is not permitted to be greater than 55%. Each of the above ratios is tested at the end of each fiscal quarter, and the debt to EBITDA ratio will be measured on a rolling four-quarter basis (with the first full year measured on an annualized basis).

 

The Credit Facility also includes customary events of default. If an event of default with respect to a borrower occurs under the Credit Facility, the lenders will be able to terminate the commitments for all borrowers and accelerate the maturity of the loans of the defaulting borrower under the Credit Facility and exercise other rights and remedies.

 

The following is a summary of the material U.S. federal income tax consequences of the acquisition, ownership, and disposition of the notes. It is based on provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), existing and proposed Treasury regulations promulgated thereunder (the “Treasury Regulations”), and administrative and judicial interpretations thereof, all as of the date hereof and all of which are subject to change, possibly on a retroactive basis. No ruling from the Internal Revenue Service (the “IRS”) has been or will be sought with respect to any aspect of the transactions described herein. Accordingly, no assurance can be given that the IRS will agree with the views expressed in this summary, or that a court will not sustain any challenge by the IRS in the event of litigation. The following relates only to notes that are acquired in the initial offering for an amount of cash equal to their issue price, which will equal the first price at which a substantial amount of the notes is sold for cash to the public (not including bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents, or wholesalers), and that are held as capital assets (i.e., generally, property held for investment).

 

This discussion does not address all of the U.S. federal income tax consequences that may be relevant to particular holders in light of their personal circumstances, or to certain types of holders that may be subject to special tax treatment (such as banks and other financial institutions, employee stock ownership plans, partnerships or other pass-through entities for U.S. federal income tax purposes, certain former citizens or residents of the United States, controlled foreign corporations, corporations that accumulate earnings to avoid U.S. federal income tax, insurance companies, tax-exempt organizations, dealers in securities and foreign currencies, brokers, persons who hold the notes as a hedge or other integrated transaction or who hedge the interest rate on the notes, “U.S. holders” (as defined below) whose functional currency is not U.S. dollars, or persons subject to the alternative minimum tax). In addition, this summary does not include any description of the tax laws of any state, local, or non-U.S. jurisdiction that may be applicable to a particular holder and does not consider any aspects of U.S. federal tax law other than income taxation.

 

For purposes of this discussion, a “non-U.S. holder” is an individual, corporation, estate, or trust that is a beneficial owner of the notes and that is not, for U.S. federal income tax purposes:

 

 

A U.S. holder is an individual, corporation, estate, or trust that is a beneficial owner of the notes and is not a non-U.S. holder.

 

The U.S. federal income tax treatment of a partner in a partnership (or other entity classified as a partnership for U.S. federal income tax purposes) that holds the notes generally will depend on such partner’s particular circumstances and on the activities of the partnership. Partners in such partnerships should consult their own tax advisors.

Interest on the notes will generally be taxable to a U.S. holder as ordinary income at the time it is paid or accrues in accordance with the U.S. holder’s method of accounting for U.S. federal income tax purposes.

Sale, Exchange, or Other Disposition of the Notes

 

In general, upon the sale, taxable exchange, redemption, retirement, or other taxable disposition of a note, a U.S. holder will recognize taxable gain or loss equal to the difference between (1) the amount of the cash and the fair market value of any property received (less any portion allocable to any accrued and unpaid interest, which will be taxable as interest to the extent not previously included in income) and (2) the U.S. holder’s adjusted tax basis in the note. Gain or loss realized on the sale, taxable exchange, redemption, retirement, or other taxable disposition of a note will generally be capital gain or loss, and will be long term capital gain or loss if you held the note for more than one year at the time of the sale, exchange, redemption, retirement, or other disposition. The deductibility of capital losses is subject to limitations.

 

Existence of the Optional Redemption

 

We do not intend to treat the possibility of the payment of additional amounts described in “Description of the Notes — Optional Redemption,” as (i) giving rise to original issue discount or recognition of ordinary income on the sale or other taxable disposition of the notes or (ii) resulting in the notes being treated as contingent payment debt instruments under the applicable Treasury Regulations. It is possible that the IRS may take a different position, in which case a holder might be required to accrue interest at a higher rate than the stated interest rate and to treat as ordinary interest income any gain realized on the taxable disposition of the notes.

 

Backup Withholding and Information Reporting

 

In general, a U.S. holder of the notes will be subject to backup withholding with respect to interest on the notes, and the proceeds of a sale of the notes, at the applicable tax rate, unless such holder (a) is an entity that is exempt from withholding (including corporations, tax-exempt organizations and certain qualified nominees) and, when required, demonstrates this fact, or (b) provides the payor with its taxpayer identification number (“TIN”), certifies that the TIN provided to the payor is correct and that the holder has not been notified by the IRS that such holder is subject to backup withholding due to underreporting of interest or dividends, and otherwise complies with applicable requirements of the backup withholding rules. In addition, such payments to U.S. holders that are not exempt entities will generally be subject to information reporting requirements. A U.S. holder who does not provide the payor with its correct TIN may be subject to penalties imposed by the IRS. The amount of any backup withholding from a payment to a U.S. holder will be allowed as a credit against such holder’s U.S. federal income tax liability and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

 

New Legislation

 

For taxable years beginning after December 31, 2012, newly enacted legislation is scheduled to impose a 3.8% tax on the “net investment income” of certain U.S. citizens and resident aliens, and on the undistributed “net investment income” of certain estates and trusts. Among other items, “net investment income” would generally include gross income from interest, less certain deductions. We urge U.S. holders to consult their own tax advisors with respect to the tax consequences of this new legislation.

 

U.S. Federal Income Tax Consequences to Non-U.S. Holders

 

Treatment of Interest

 

Subject to the discussion of backup withholding below, under the “portfolio interest exemption,” a non-U.S. holder will generally not be subject to U.S. federal income tax (or any withholding tax) on payments of interest on the notes if the interest is not effectively connected with its conduct of a U.S. trade or business, provided that:

 

 

 

 

If the requirements of the portfolio interest exemption described above are not satisfied, a 30% withholding tax will apply to the gross amount of interest on the notes that is paid to a non-U.S. holder, unless either: (a) an applicable income tax treaty reduces or eliminates such tax, and the non-U.S. holder claims the benefit of that treaty by providing a properly completed and duly executed IRS Form W-8BEN (or suitable successor or substitute form) establishing qualification for benefits under the treaty, or (b) the interest is effectively connected with the non-U.S. holder’s conduct of a trade or business in the United States and the non-U.S. holder provides an appropriate statement to that effect on a properly completed and duly executed IRS Form W-8ECI (or suitable successor form).

 

If a non-U.S. holder is engaged in a trade or business in the United States and interest on a note is effectively connected with the conduct of that trade or business, the non-U.S. holder will be required to pay U.S. federal income tax on that interest on a net income basis (and the 30% withholding tax described above will not apply provided the duly executed IRS Form W-8ECI is provided to us or our paying agent) generally in the same manner as a U.S. person. If a non-U.S. holder is eligible for the benefits of an income tax treaty between the United States and its country of residence, and the non-U.S. holder claims the benefit of the treaty by properly submitting an IRS Form W-8BEN, any interest income that is effectively connected with a U.S. trade or business will be subject to U.S. federal income tax in the manner specified by the treaty and generally will only be subject to tax on a net basis if such income is attributable to a permanent establishment (or a fixed base in the case of an individual) maintained by the non-U.S. holder in the United States. In addition, a non-U.S. holder that is treated as a foreign corporation for U.S. federal income tax purposes may be subject to a branch profits tax equal to 30% (or lower applicable treaty rate) of its earnings and profits for the taxable year, subject to adjustments, that are effectively connected with its conduct of a trade or business in the United States.

 

Sale, Exchange, or Other Disposition of the Notes

 

Subject to the discussion of backup withholding below, a non-U.S. holder generally will not be subject to U.S. federal income tax (or any withholding thereof) on any gain (other than any gain attributable to accrued interest, which will be taxed in the manner described above under the heading “U.S. Federal Income Tax Consequences to Non-U.S. Holders — Treatment of Interest”) realized by such holder upon a sale, taxable exchange, redemption, retirement, or other taxable disposition of a note, unless:

 

 

If the first exception applies, the non-U.S. holder generally will be subject to U.S. federal income tax at a rate of 30% on the amount by which its U.S.-source capital gains exceed its U.S.-source capital losses. If the second

exception applies, the non-U.S. holder will generally be subject to U.S. federal income tax on the net gain derived from the sale, taxable exchange, redemption, retirement, or other taxable disposition of the notes in the same manner as a U.S. person. In addition, corporate non-U.S. holders may be subject to a 30% branch profits tax on any such effectively connected gain. If a non-U.S. holder is eligible for the benefits of an income tax treaty between the United States and its country of residence, the U.S. federal income tax treatment of any such gain may be modified in the manner specified by the treaty.

 

Information Reporting and Backup Withholding

 

When required, we or our paying agent will report to the IRS and to each non-U.S. holder the amount of any interest paid on the notes in each calendar year, and the amount of U.S. federal income tax withheld, if any, with respect to these payments.

 

Non-U.S. holders who have provided certification as to their non-U.S. status or who have otherwise established an exemption will generally not be subject to backup withholding tax on payments of interest if neither we nor our agent have actual knowledge or reason to know that such certification is unreliable or that the conditions of the exemption are in fact not satisfied.

 

Payments of the proceeds from the sale of a note to or through a foreign office of a broker generally will not be subject to information reporting or backup withholding. However, additional information reporting, but generally not backup withholding, may apply to those payments if the broker has certain relationships with the United States.

 

Payment of the proceeds from a sale of a note (including a retirement or redemption) to or through the United States office of a broker will be subject to information reporting and backup withholding unless the non-U.S. holder certifies as to its non-U.S. status or otherwise establishes an exemption from information reporting and backup withholding.

 

The amount of any backup withholding from a payment to a non-U.S. holder will be allowed as a credit against such holder’s U.S. federal income tax liability, if any, and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

 

Williams Partners intends to offer the notes through the underwriters named below, for whom Deutsche Bank Securities Inc., J.P. Morgan Securities LLC and RBC Capital Markets, LLC are acting as representatives. Subject to the terms and conditions contained in the underwriting agreement dated the date of this prospectus supplement between Williams Partners and the underwriters named below, Williams Partners has agreed to sell to the underwriters and the underwriters have severally agreed to purchase, the principal amount of the notes listed opposite their names below.

 

 

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters have agreed to purchase all of the notes sold pursuant to the underwriting agreement if any of the notes are purchased. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

 

The underwriters have advised Williams Partners that they propose initially to offer the notes to the public at the public offering price on the cover page of this prospectus supplement, and to dealers at that price less a concession not in excess of     % of the principal amount of the notes. The underwriters may allow, and the dealers may reallow, a discount not in excess of     % of the principal amount of the notes to other dealers. After the initial offering of the notes to the public, the public offering price, concession and discount may be changed.

 

The following table shows the underwriting discounts and commissions that we are to pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the notes).

 

 

The expenses of the offering, not including the underwriting discount, are estimated to be $     and are payable by Williams Partners.

 

The notes are a new issue of securities with no established trading market. Williams Partners does not intend to apply for listing of the notes on any national securities exchange or for quotation of the notes on any automated dealer quotation system. Williams Partners cannot assure the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected.

 

Williams Partners has agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

 

In connection with the offering, the underwriters are permitted to engage in transactions that stabilize the market price of the notes. Such transactions consist of bids or purchases to peg, fix or maintain the price of the notes. If the underwriters create a short position in the notes in connection with the offering, i.e., if they sell more notes

than are on the cover page of this prospectus supplement, the underwriters may reduce that short position by purchasing notes in the open market. Purchases of a security to stabilize the price or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases.

 

Neither Williams Partners nor the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the notes. In addition, neither Williams Partners nor the underwriters make any representation that the underwriters will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

 

Extended Settlement

 

We expect that delivery of the notes will be made against payment therefor on or about the closing date specified on the cover page of this prospectus supplement, which will be the     business day following the date hereof, or T +     . Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of pricing or the next      succeeding business days will be required, by virtue of the fact that the notes initially will settle in T +     , to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes on the date of pricing or the next      succeeding business days should consult their own advisor.

 

Relationships

 

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of the issuer. The underwriters and their respective affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

 

Some of the underwriters and their affiliates have engaged, and may in the future engage, in commercial banking, investment banking or financial advisory transactions with us, our affiliates and The Williams Companies, Inc., in the ordinary course of their business. Such underwriters and their affiliates have received customary compensation and expenses for these commercial banking, investment banking or financial advisory transactions. For instance, JPMorgan Chase Bank, N.A., Deutsche Bank AG New York Branch, Mizuho Corporate Bank (USA), Royal Bank of Canada, The Bank of Tokyo-Mitsubishi UFJ, Ltd., The Toronto-Dominion Bank, New York Branch and U.S. Bank National Association, which are affiliates of the underwriters, are lenders under our Credit Facility.

 

Certain matters with respect to the issuance and sale of the notes offered hereby will be passed upon for us by Gibson, Dunn & Crutcher LLP. Certain tax matters will be passed upon for us by Andrews Kurth LLP, Houston, Texas. Certain legal matters with respect to the notes will be passed upon for the underwriters by Latham & Watkins LLP, New York, New York.

TABLE OF CONTENTS

 

 

This prospectus is part of a registration statement on Form S-3 we filed with the Securities and Exchange Commission (SEC) using a “shelf” registration process. Under this shelf registration process, we may, over time, offer and sell in one or more offerings in any combination, an unlimited number and amount of the common units or debt securities of Williams Partners L.P. described in this prospectus. This prospectus generally describes us, the common units of Williams Partners L.P., the debt securities of Williams Partners L.P. and the guarantees of the debt securities.

 

Each time we sell common units or debt securities with this prospectus, we will describe in a prospectus supplement, which will be delivered with this prospectus, specific information about the offering and the terms of the particular securities offered. The prospectus supplement also may add to, update, or change the information contained in this prospectus. If there is any inconsistency between the information contained in this prospectus and any information incorporated by reference herein, on the one hand, and the information contained in any applicable prospectus supplement or incorporated by reference therein, on the other hand, you should rely on the information in the applicable prospectus supplement or incorporated by reference therein.

 

Wherever references are made in this prospectus to information that will be included in a prospectus supplement, to the extent permitted by applicable law, rules, or regulations, we may instead include such information or add, update, or change the information contained in this prospectus by means of a post-effective amendment to the registration statement of which this prospectus is a part through filings we make with the SEC that are incorporated by reference into this prospectus or by any other method as may then be permitted under applicable law, rules, or regulations.

 

Statements made in this prospectus, in any prospectus supplement or in any document incorporated by reference in this prospectus or any prospectus supplement as to the contents of any contract or other document are not necessarily complete. In each instance we refer you to the copy of the contract or other document filed as an exhibit to the registration statement of which this prospectus is a part, or as an exhibit to the documents incorporated by reference. You may obtain copies of those documents as described in this prospectus under “Where You Can Find More Information.”

 

Neither the delivery of this prospectus nor any sale made under it implies that there has been no change in our affairs or that the information in this prospectus is correct as of any date after the date of this prospectus. You should not assume that the information in this prospectus, including any information incorporated in this prospectus by reference, the accompanying prospectus supplement or any free writing prospectus prepared by us, is accurate as of any date other than the date on the front of those documents. Our business, financial condition, results of operations and prospects may have changed since that date.

 

You should rely only on the information contained in or incorporated by reference in this prospectus or a prospectus supplement. We have not authorized anyone to provide you with different information. We are not making an offer to sell securities in any jurisdiction where the offer or sale of such securities is not permitted.

 

Unless the context clearly indicates otherwise, references in this prospectus to “we,” “our,” “us” or like terms refer to Williams Partners L.P. and its subsidiaries. Unless the context clearly indicates otherwise, references to “we,” “our,” “us” or like terms include the operations of Wamsutter LLC (Wamsutter) and Discovery Producer Services LLC (Discovery), in which we own interests accounted for as equity investments that are not consolidated in our financial statements. When we refer to Wamsutter or Discovery by name, we are referring exclusively to their respective businesses and operations.

 

We are a publicly traded Delaware limited partnership formed by The Williams Companies, Inc. (Williams) in February 2005 to own, operate and acquire a diversified portfolio of complementary energy assets. We gather, transport, process and treat natural gas and fractionate and store natural gas liquids (NGLs). Fractionation is the process by which a mixed stream of NGLs is separated into its constituent products, such as ethane, propane and butane. These NGLs result from natural gas processing and crude oil refining and are used as petrochemical feedstocks, heating fuels and gasoline additives, among other applications.

Operations of our businesses are located in the United States. We manage our business and analyze our results of operations on a segment basis. Our operations are divided into three business segments:

 

 

Our assets were owned by Williams prior to the initial public offering of our common units in August 2005, our acquisition of Four Corners in 2006, our acquisition of an additional 20% ownership percentage of Discovery in 2007 and our acquisition of the Wamsutter Ownership Interests in 2007. Williams indirectly owns an approximate 21.6% limited partnership interest in us and all of our 2% general partner interest. We account for our interests in Wamsutter and our 60% interest in Discovery as an equity investment, and therefore do not consolidate their financial results.

 

Williams is an integrated energy company that trades on the New York Stock Exchange under the symbol “WMB.” Williams operates in a number of segments of the energy industry, including natural gas exploration and production, interstate natural gas transportation and midstream services. Williams has been in the midstream natural gas and NGL industry for more than 20 years.

 

Williams Partners GP LLC, the general partner of Williams Partners L.P., is an indirect wholly owned subsidiary of Williams and holds a 2% general partner interest, a 6% limited partner interest and the incentive distribution rights in Williams Partners L.P.

 

Our principal executive offices are located at One Williams Center, Tulsa, Oklahoma 74172-0172, and our phone number is 918-573-2000.

 

We are a holding company with no independent assets or operations. We own a 100% member interest in Williams Partners Operating LLC, a Delaware limited liability company (Williams Operating). Williams Operating owns a 100% member interest in each of Carbonate Trend Pipeline LLC (Carbonate Trend), Mid-Continent Fractionation and Storage, LLC (Mid-Continent) and Four Corners.

 

Occasionally, in this prospectus, we refer to Williams Operating, Carbonate Trend, Mid-Continent and Four Corners as the “Subsidiary Guarantors.” Other than the Subsidiary Guarantors, our only other consolidated subsidiary is minor. Any guarantees of our debt securities by the Subsidiary Guarantors will be full and unconditional and joint and several.

 

We are subject to the informational requirements of the Securities Exchange Act of 1934, as amended (Exchange Act), and file reports and other information with the SEC. The public may read and copy any reports or other information that we file with the SEC at the SEC’s public reference room, 100 F Street NE, Washington, D.C. 20549-2521. The public may obtain information on the operation of the public reference room by calling the SEC at 1-800-SEC-0330.

You may also inspect our SEC reports on our website at http://www.williamslp.com. We make available free of charge on or through our Internet website our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act, as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. Information contained on our website is not intended to be incorporated by reference in this prospectus, and you should not consider that information a part of this prospectus.

 

 

We are incorporating by reference into this prospectus information we have filed with the SEC, which means we are disclosing important information to you without actually including the specific information in this prospectus by referring you to other documents filed separately with the SEC. The information incorporated by reference is considered part of this prospectus, unless we update or supersede that information by the information contained in this prospectus or the information we file subsequently that is incorporated by reference into this prospectus or any prospectus supplement. Information that we later provide to the SEC, and which is deemed to be “filed” with the SEC, automatically will update information previously filed with the SEC, and may replace information in this prospectus.

 

We are incorporating by reference in this prospectus the following documents that we have filed with the SEC:

 

 

These reports contain important information about us, our financial condition and our results of operations.

All documents that we file with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act), after the date of this prospectus and prior to the termination of all offerings made pursuant to this prospectus and the applicable prospectus supplement also will be deemed to be incorporated herein by reference. Nothing in this prospectus shall be deemed to incorporate information furnished to but not filed with the SEC, including pursuant to Item 2.02 or Item 7.01 of Form 8-K (or corresponding information furnished under Item 9.01 or included as an exhibit).

 

Limited partner interests are inherently different from the capital stock of a corporation, although many of the business risks to which we are subject are similar to those that would be faced by a corporation engaged in a similar business. Before you invest in our securities, you should carefully consider those risk factors included in our most-recent Annual Report on Form 10-K, as supplemented by our Quarterly Reports on Form 10-Q, that are incorporated herein by reference and those that may be included in the applicable prospectus supplement, together with all of the other information included in this prospectus, any prospectus supplement and the documents we incorporate by reference in evaluating an investment in our securities.

 

If any of the risks discussed in the foregoing documents were actually to occur, our business, financial condition, results of operations, or cash flow could be materially adversely affected. In that case, our ability to make distributions to our unitholders or pay interest on, or the principal of, any debt securities, may be reduced, the trading price of our securities could decline and you could lose all or part of your investment.

The following sets forth certain general terms and provisions of the base indenture under which the debt securities are to be issued, unless otherwise specified in a prospectus supplement. The particular terms of the debt securities to be sold will be set forth in a prospectus supplement relating to such debt securities.

 

As used in this description, the words, “we,” “us” and “our” refer to Williams Partners L.P. and not to any of its subsidiaries or affiliates.

 

The debt securities will represent our unsecured general obligations, unless otherwise provided in the applicable prospectus supplement. As indicated in the applicable prospectus supplement, the debt securities will either be senior debt securities or subordinated debt securities and, if applicable, will be the general obligations of the Subsidiary Guarantors. Unless otherwise specified in the applicable prospectus supplement, the debt securities will be issued under an indenture to be entered into between us and The Bank of New York Mellon Trust Company, N.A., as trustee, that has been filed as an exhibit to the registration statement of which this prospectus is a part, subject to such amendments or supplemental indentures as are adopted from time to time. The following summary of certain provisions of that indenture does not purport to be complete and is subject to, and qualified in its entirety by, reference to all the provisions of that indenture, including the definitions therein of certain terms. Wherever particular sections or defined terms of the indenture are referred to, it is intended that such sections or defined terms shall be incorporated herein by reference. We urge you to read the indenture filed as an exhibit to the registration statement of which this prospectus is a part because that indenture, as amended or supplemented from time to time, and not this description, governs your rights as a holder of debt securities.

 

General

 

The indenture does not limit the amount of debt securities that may be issued thereunder. The applicable prospectus supplement with respect to any debt securities will set forth the terms of the debt securities offered pursuant thereto, including some or all of the following:

 

 

 

This description of debt securities will be deemed modified, amended or supplemented by any description of any series of debt securities set forth in a prospectus supplement related to that series.

 

The prospectus supplement may also describe any material United States federal income tax consequences or other special considerations regarding the applicable series of debt securities, including those relating to:

 

 

 

Debt securities may be presented for exchange, conversion or transfer in the manner, at the places and subject to the restrictions set forth in the indenture, as amended or supplemented, and the applicable prospectus supplement. Such services will be provided without charge, other than any tax or other governmental charge payable in connection therewith, but subject to the limitations provided in the indenture, as amended or supplemented.

 

The indenture does not contain any covenant or other specific provision affording protection to holders of the debt securities in the event of a highly leveraged transaction or a change in control of the Company, except to the limited extent described below under “— Consolidation, Merger and Sale of Assets” or as provided in any supplemental indenture.

 

Guarantees

 

One or more of our subsidiaries may become a guarantor of a particular series of debt securities if and to the extent provided in a prospectus supplement and an indenture supplement or a resolution of the board of directors of our general partner and accompanying officers’ certificate relating to such series of debt securities. Each of our subsidiaries that becomes a guarantor of the debt securities of such series, and any of our subsidiaries that is a successor thereto, will fully, irrevocably, unconditionally and absolutely guarantee the due and punctual payment of the principal of, and premium, if any, and interest on such debt securities, and all other amounts due and payable under the indenture and such debt securities by us to the trustee and the holders of such debt securities. The terms of any such guarantees may provide for their release upon the occurrence of certain events, such as the debt securities of a series subject to such guarantees achieving an investment grade rating.

 

Modification and Waiver

 

The indenture provides we and the trustee may enter into one or more supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the indenture or of modifying in any manner the rights of the holders of debt securities of a series under the indenture or the debt securities of such series, with the consent of the holders of a majority (or such greater amount as is provided for with respect to such series) in principal amount of the outstanding debt securities of such series, voting as a single class; provided that no such supplemental indenture may, without the consent of the holder of each such debt security affected thereby, among other things:

 

(a) change the stated maturity of the principal of, or any premium, interest or additional amounts on, such debt securities, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest or any additional amounts thereon, or reduce any premium payable on redemption thereof or otherwise, or reduce the amount of the principal of debt securities issued with original issue discount that would be due and payable upon an acceleration of the maturity thereof or the amount thereof provable in bankruptcy, or change the redemption provisions or adversely affect the right of repayment at the option of the holder, or change the place of payment or currency in which the principal of, or any premium, interest or additional amounts with respect to, any debt security is payable, or impair or affect the right of any holder of debt securities to institute suit for the payment after such payment is due;

 

(b) reduce the percentage of outstanding debt securities of any series, the consent of the holders of which is required for any such supplemental indenture, or the consent of whose holders is required for any waiver or reduce the quorum required for voting;

 

(c) modify any of the provisions of the sections of the indenture relating to supplemental indentures with the consent of the holders or waivers of past defaults or certain covenants, except to increase any percentage set forth therein or to provide that certain other provisions of the indenture cannot be modified or waived without the consent of each holder affected thereby; or

(d) make any change that adversely affects the right to convert or exchange any security into or for common units or other securities, cash or other property in accordance with the terms of the applicable debt security.

 

The indenture provides that a supplemental indenture that changes or eliminates any covenant or other provision of the indenture that has expressly been included solely for the benefit of one or more particular series of debt securities, or that modifies the rights of the holders of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the indenture of the holders of debt securities of any other series.

 

The indenture provides that we and the applicable trustee may, without the consent of the holders of any series of debt securities issued thereunder, enter into one or more supplemental indentures for any of the following purposes:

 

(a) to evidence the succession of another person and the assumption by any such successor of our covenants in the indenture and in the debt securities issued thereunder;

 

(b) to add to our covenants or to surrender any right or power conferred on us pursuant to the indenture;

 

(c) to establish the form and terms of debt securities issued thereunder;

 

(d) to evidence and provide for a successor trustee under the indenture with respect to one or more series of debt securities issued thereunder or to provide for or facilitate the administration of the trusts under the indenture by more than one trustee;

 

(e) to cure any ambiguity, to correct or supplement any provision in the indenture that may be defective or inconsistent with any other provision of the indenture or to make any other provisions with respect to matters or questions arising under such indenture; provided that no such action pursuant to this clause (e) shall adversely affect the interests of the holders of any series of debt securities issued thereunder in any material respect;

 

(f) to add to, delete from or revise the conditions, limitations and restrictions on the authorized amount, terms or purposes of issue, authentication and delivery of securities under the indenture;

 

(g) to add any additional events of default with respect to all or any series of debt securities;

 

(h) to supplement any of the provisions of the indenture as may be necessary to permit or facilitate the defeasance and discharge of any series of debt securities, provided that such action does not adversely affect the interests of any holder of an outstanding debt security of such series or any other security in any material respect;

 

(i) to make provisions with respect to the conversion or exchange rights of holders of debt securities of any series;

 

(j) to pledge to the trustee as security for the debt securities of any series any property or assets;

 

(k) to add guarantees in respect of the debt securities of one or more series;

 

(l) to change or eliminate any of the provisions of the indenture, provided that any such change or elimination will become effective only when there is no security of any series outstanding created prior to the execution of such supplemental indenture which is entitled to the benefit of such provision;

 

(m) to provide for certificated securities in addition to or in place of global securities;

 

(n) to qualify the indenture under the Trust Indenture Act of 1939, as amended;

 

(o) with respect to the debt securities of any series, to conform the text of the indenture or the debt securities of such series to any provision of the description thereof in our offering memorandum or prospectus relating to the initial offering of such debt securities, to the extent that such provision, in our good faith judgment, was intended to be a verbatim recitation of a provision of the indenture or such securities; or

(p) to make any other change that does not adversely affect the rights of holders of any series of debt securities issued thereunder in any material respect.

 

Events of Default

 

Unless otherwise provided in the supplemental indenture or board resolution and officer’s certificate establishing the terms of any series of debt securities and the prospectus supplement relating to such series, the following will be events of default under the indenture with respect to each series of debt securities issued thereunder:

 

(a) default for 30 days in the payment when due of interest on, or any additional amount in respect of, any such series of debt securities;

 

(b) default in the payment of principal or any premium on the debt securities of such series when due;

 

(c) default in the payment, if any, of any sinking fund installment when and as due by the terms of any debt security of such series, subject to any cure period that may be specified in any debt security of such series;

 

(d) failure by us for 60 days after receipt of written notice from the trustee upon instruction from holders of at least 25% in principal amount of the then outstanding debt securities of such series to comply with any of the other agreements in the indenture and stating that such notice is a “Notice of Default” under the indenture; provided, that if such failure cannot be remedied within such 60-day period, such period shall be automatically extended by another 60 days so long as (i) such failure is subject to cure and (ii) we are using commercially reasonable efforts to cure such failure; and provided, further, that a failure to comply with any such other agreement in the indenture that results from a change in generally accepted accounting principles shall not be deemed to be an event of default;

 

(e) certain events of bankruptcy, insolvency or reorganization of us; and

 

(f) any other event of default provided in a supplemental indenture with respect to a particular series of debt securities, provided that any event of default that results from a change in generally accepted accounting principles shall not be deemed to be an event of default.

 

In case an event of default specified in clause (a) or (b) above shall occur and be continuing with respect to any series of debt securities, holders of at least 25%, and in case an event of default specified in any clause other than clause (a), (b) or (e) above shall occur and be continuing with respect to any series of debt securities, holders of at least a majority, in aggregate principal amount of the debt securities of such series then outstanding may declare the principal (or, in the case of discounted debt securities, the amount specified in the terms thereof) of such series to be due and payable. If an event of default described in clause (e) above shall occur and be continuing then the principal amount (or, in the case of discounted debt securities, the amount specified in the terms thereof) of all the debt securities outstanding shall be and become due and payable immediately, without notice or other action by any holder or the applicable trustee, to the full extent permitted by law. Any past or existing default or event of default with respect to particular series of debt securities under such indenture may be waived by the holders of a majority in aggregate principal amount of the outstanding debt securities of such series, except in each case a continuing default (1) in the payment of the principal of, any premium or interest on, or any additional amounts with respect to, any debt security of such series, or (2) in respect of a covenant or provision which cannot be modified or amended without the consent of each holder affected thereby.

 

The indenture provides that the applicable trustee may withhold notice to the holders of any default with respect to any series of debt securities (except in payment of principal of or interest or premium on, or additional amounts or a sinking fund payment in respect of, the debt securities) if the applicable trustee considers it in the interest of holders to do so.

 

The indenture contains a provision entitling the applicable trustee to be indemnified by the holders before proceeding to exercise any trust or power under the indenture at the request of such holders. The indenture provides that the holders of a majority in aggregate principal amount of the then outstanding debt securities of any series may direct the time, method and place of conducting any proceedings for any remedy available to the applicable trustee or of exercising any trust or power conferred upon the applicable trustee with respect to the debt securities of such series; provided, however, that the applicable trustee may decline to follow any such direction if, among other

reasons, the applicable trustee determines that the actions or proceedings as directed would be unduly prejudicial to the holders of the debt securities of such series not joining in such direction. The right of a holder to institute a proceeding with respect to a series of debt securities will be subject to certain conditions precedent including, without limitation, that in case of an event of default specified in clause (a), (b) or (e) of the first paragraph above under “— Events of Default,” holders of at least 25%, or in case of an event of default other than specified in clause (a), (b) or (e) of the first paragraph above under “— Events of Default”, holders of at least a majority, in aggregate principal amount of the debt securities of such series then outstanding make a written request upon the applicable trustee to exercise its powers under such indenture, indemnify the applicable trustee and afford the applicable trustee reasonable opportunity to act. Notwithstanding the foregoing, the holder has an absolute right to receipt of the principal of, premium, if any, and interest on and additional amounts with respect to the debt securities when due and to institute suit for the enforcement thereof.

 

Consolidation, Merger and Sale of Assets

 

The indenture provides that we may not directly or indirectly consolidate with or merge with or into, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of our assets and properties and the assets and properties of our subsidiaries (taken as a whole) to another person in one or more related transactions unless we are the survivor or the successor person is a person organized under the laws of any domestic jurisdiction and assumes our obligations on the debt securities issued thereunder, and under the indenture, and after giving effect thereto no event of default, and no event that, after notice or lapse of time or both, would become an event of default, shall have occurred and be continuing, and certain other conditions are met.

 

Certain Covenants

 

The covenants set forth in the indenture include the following:

 

Payment of Principal, any Premium, Interest or Additional Amounts.  We will duly and punctually pay the principal of, and premium and interest on or any additional amounts payable with respect to, any debt securities of any series in accordance with their terms.

 

Maintenance of Office or Agency.  We will be required to maintain an office or agency in each place of payment for each series of debt securities for notice and demand purposes and for the purposes of presenting or surrendering debt securities for payment, registration of transfer or exchange.

 

Reports.  So long as any debt securities of a particular series are outstanding, we will file with the trustee, within 30 days after we have filed the same with the SEC, unless such reports are available on the SEC’s Electronic Data Gathering, Analysis, and Retrieval (EDGAR) filing system (or any successor thereto), copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may from time to time by rules and regulations prescribe) which we may be required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if we are not required to file information, documents or reports pursuant to either of said Sections, then we shall file with the trustee and the SEC, in accordance with rules and regulations prescribed from time to time by the SEC, such of the supplementary and periodic information, documents and reports which may be required pursuant to Section 13 of the Exchange Act in respect of a security listed and registered on a national securities exchange as may be prescribed from time to time in such rules and regulations.

 

Additional Covenants.  Any additional covenants with respect to any series of debt securities will be set forth in the supplemental indenture or board resolution and officer’s certificate and prospectus supplement relating thereto.

 

Conversion Rights

 

The terms and conditions, if any, upon which the debt securities of any series are convertible into common units or other securities will be set forth in the applicable supplemental indenture or board resolution and officer’s certificate and prospectus supplement relating thereto. Such terms will include the conversion price (or manner of calculation thereof), the conversion period, provisions as to whether conversion will be at our option or the option of

the holders, the events requiring an adjustment of the conversion price, provisions affecting conversion in the event of redemption of such debt securities and any restrictions on conversion.

 

Redemption; Repurchase at the Option of the Holder; Sinking Fund

 

The terms and conditions, if any, upon which (a) the debt securities of any series are redeemable at our option, (b) the holder of debt securities of any series may cause us to repurchase such debt securities or (c) the debt securities of any series are subject to any sinking fund will be set forth in the applicable supplemental indenture or board resolution and officer’s certificate and prospectus supplement relating thereto.

 

Repurchases on the Open Market

 

We or any affiliate of ours may at any time or from time to time repurchase any debt security in the open market or otherwise. Such debt securities may, at our option or the option of our relevant affiliate, be held, resold or surrendered to the trustee for cancellation.

 

Discharge, Defeasance and Covenant Defeasance

 

The indenture provides, with respect to each series of debt securities issued thereunder, that we may satisfy and discharge our obligations under the indenture with respect to debt securities of such series if:

 

(a) (i) all debt securities of such series previously authenticated and delivered, with certain exceptions, have been accepted by the applicable trustee for cancellation; or

 

(ii) the debt securities of such series have become due and payable, or mature within one year, or all of them are to be called for redemption within one year under arrangements satisfactory to the applicable trustee for giving the notice of redemption and we irrevocably deposit in trust with the applicable trustee, as trust funds solely for the benefit of the holders of such debt securities, for that purpose, money or governmental obligations or a combination thereof sufficient (in the opinion of a nationally recognized independent registered public accounting firm expressed in a written certification thereof delivered to the applicable trustee) to pay the entire indebtedness on the debt securities of such series to maturity or redemption, as the case may be;

 

(b) we have paid all other sums payable by us under the indenture; and

 

(c) we deliver to the applicable trustee an officers’ certificate and an opinion of counsel, in each case stating that all conditions precedent provided for in the indenture relating to the satisfaction and discharge of the indenture with respect to the debt securities of such series have been complied with.

 

Notwithstanding such satisfaction and discharge, our obligations to compensate and indemnify the trustee, to pay additional amounts, if any, in respect of debt securities in certain circumstances and to convert or exchange debt securities pursuant to the terms thereof and our obligations and the obligations of the trustee to hold funds in trust and to apply such funds pursuant to the terms of the indenture, with respect to issuing temporary debt securities, with respect to the registration, transfer and exchange of debt securities, with respect to the replacement of mutilated, destroyed, lost or stolen debt securities and with respect to the maintenance of an office or agency for payment, shall in each case survive such satisfaction and discharge.

 

Unless inapplicable to debt securities of a series pursuant to the terms thereof, the indenture provides that (i) we will be deemed to have paid and will be discharged from any and all obligations in respect of the debt securities issued thereunder of any series, and the provisions of such indenture will, except as noted below, no longer be in effect with respect to the debt securities of such series (“defeasance”) and (ii) (1) we may omit to comply with the covenant under “— Consolidation, Merger and Sale of Assets” and any other additional covenants established pursuant to the terms of such series, and such omission shall be deemed not to be an event of default under clause (d) or (f) of the first paragraph of “— Events of Default” and (2) the occurrence of any event described in clause (f) of the first paragraph of “— Events of Default” shall not be deemed to be an event of default, in each case with respect

to the outstanding debt securities of such series ((1) and (2) of this clause (ii), “covenant defeasance”); provided that the following conditions shall have been satisfied with respect to such series:

 

(a) we have irrevocably deposited in trust with the applicable trustee, as trust funds solely for the benefit of the holders of the debt securities of such series, for that purpose, money or government obligations or a combination thereof sufficient (in the opinion of a nationally recognized independent registered public accounting firm expressed in a written certification thereof delivered to the applicable trustee) without consideration of any reinvestment to pay and discharge the principal of, premium, if any, and accrued interest and additional amounts on the outstanding debt securities of such series to maturity or earlier redemption (irrevocably provided for under arrangements satisfactory to the applicable trustee), as the case may be;

 

(b) such defeasance or covenant defeasance will not result in a breach or violation of, or constitute a default under, the indenture or any other material agreement or instrument to which we are a party or by which we are bound;

 

(c) no event of default or event which with notice or lapse of time would become an event of default with respect to such debt securities of such series shall have occurred and be continuing on the date of such deposit;

 

(d) we shall have delivered to such trustee an opinion of counsel as described in the indenture to the effect that the holders of the debt securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred;

 

(e) we have delivered to the applicable trustee an officers’ certificate and an opinion of counsel, in each case stating that all conditions precedent provided for in the indenture relating to the defeasance contemplated have been complied with;

 

(f) if the debt securities are to be redeemed prior to their maturity, notice of such redemption shall have been duly given or provision therefor satisfactory to the trustee shall have been made; and

 

(g) any such defeasance or covenant defeasance shall comply with any additional or substitute terms provided for by the terms of the debt securities of such series.

 

Notwithstanding a defeasance, among other obligations, our obligations with respect to the following will survive with respect to the debt securities of such series until otherwise terminated or discharged under the terms of the indenture:

 

(a) the rights of holders of outstanding debt securities of such series to receive payments in respect of the principal of, interest on or premium or additional amounts, if any, payable in respect of, such debt securities when such payments are due from the trust referred in clause (a) in the preceding paragraph and any rights of such holders to convert or exchange such debt securities for other securities or property;

 

(b) the issuance of temporary debt securities, the registration, transfer and exchange of debt securities, the replacement of mutilated, destroyed, lost or stolen debt securities and the maintenance of an office or agency for payment and holding payments in trust;

 

(c) the rights, powers, trusts, duties and immunities of the trustee, and our obligations in connection therewith; and

 

(d) the defeasance or covenant defeasance provisions of the indenture.

 

Limitation of Liability

 

Our unitholders, our general partner and its directors, officers and members will not be liable for our obligations under the debt securities, the indenture or the guarantees or for any claim based on, or in respect of, such obligations. By accepting a debt security, each holder of that debt security will have agreed to this provision and waived and released any such liability on the part of our unitholders, our general partner and its directors, officers and members. This waiver and release are part of the consideration for our issuance of the debt securities. It is the

view of the SEC that a waiver of liabilities under the federal securities laws is against public policy and unenforceable.

 

Applicable Law

 

The indenture provides that the debt securities and the indenture will be governed by and construed in accordance with the laws of the State of New York.

 

About the Trustee

 

Unless otherwise specified in the applicable prospectus supplement, The Bank of New York Mellon Trust Company, N.A. is the trustee under the indenture.

 

The Units

 

The holders of common units are entitled to participate in partnership distributions and exercise the rights or privileges available to limited partners under our partnership agreement. For a description of the relative rights and preferences of holders of common units in and to partnership distributions, please read this section and “Provisions of Our Partnership Agreement Relating to Cash Distributions.” For a description of the rights and privileges of limited partners under our partnership agreement, including voting rights, please read “The Partnership Agreement.”

 

Transfer Agent and Registrar

 

Duties

 

Computershare Trust Company, N.A. serves as registrar and transfer agent for the common units. We pay all fees charged by the transfer agent for transfers of common units, except the following that must be paid by unitholders:

 

 

There is no charge to unitholders for disbursements of our cash distributions. We will indemnify the transfer agent against all claims and losses that may arise out of all actions of the transfer agent or its agents or subcontractors for their activities in that capacity, except for any liability due to any gross negligence or willful misconduct of the transfer agent or its agents or subcontractors.

 

Resignation or Removal

 

The transfer agent may resign, by notice to us, or be removed by us. The resignation or removal of the transfer agent will become effective upon our appointment of a successor transfer agent and registrar and its acceptance of the appointment. If no successor has been appointed and has accepted the appointment within 30 days after notice of the resignation or removal, our general partner may act as the transfer agent and registrar until a successor is appointed.

 

Transfer of Common Units

 

By transfer of common units or the issuance of common units in a merger or consolidation in accordance with our partnership agreement, each transferee of common units will be admitted as a limited partner with respect to the

common units transferred when such transfer and admission is reflected in our books and records. Additionally, each transferee:

 

 

An assignee will become a substituted limited partner of our partnership for the transferred common units automatically upon the recording of the transfer on our books and records. Our general partner will cause any transfers to be recorded on our books and records no less frequently than quarterly.

 

We may, at our discretion, treat the nominee holder of a common unit as the absolute owner. In that case, the beneficial holder’s rights are limited solely to those that it has against the nominee holder as a result of any agreement between the beneficial owner and the nominee holder.

 

Common units are securities and are transferable according to the laws governing transfer of securities. Until a common unit has been transferred on our books, we and the transfer agent may treat the record holder of the unit as the absolute owner for all purposes, except as otherwise required by law or stock exchange regulations.

 

Subordinated Units

 

On February 19, 2008, following fulfillment of the financial test contained in the partnership agreement, all of our outstanding subordinated units converted into common units on a one-for-one basis. As a result, we no longer have any outstanding subordinated units.

 

Set forth below is a summary of the significant provisions of our partnership agreement that relate to cash distributions.

 

Operating Surplus and Capital Surplus

 

General

 

Our partnership agreement requires that, within 45 days after the end of each quarter, we distribute all of our available cash to unitholders of record on the applicable record date.

 

Definition of Available Cash

 

Available cash generally means, for each fiscal quarter all cash on hand at the end of the quarter:

 

 

 

 

Wamsutter’ Cash Distribution Policy

 

A substantial portion of our cash available to pay distributions will be cash we receive as distributions from Wamsutter. Wamsutter’s limited liability company agreement, as amended, provides for the distribution of available cash at least quarterly, with available cash defined to mean, for each fiscal quarter, cash generated from Wamsutter’s business less reserves that are necessary or appropriate to provide for the conduct of its business and to comply with applicable law or any debt instrument or other agreement to which it is a party. Under Wamsutter’s limited liability company agreement, the amount of Wamsutter’s quarterly distributions, including the amount of cash reserves not distributed, will be determined by the member of Wamsutter’s management committee representing the Class B Interests. We own 100% of the Class A interests in Wamsutter and 68% of the Class C interests in Wamsutter, and an affiliate of Williams owns 100% of the Class B interests in Wamsutter and the remaining 32% of the Class C interests. Wamsutter’s limited liability agreement may only be amended with the unanimous approval of all its members.

 

Discovery’s Cash Distribution Policy

 

A significant portion of our cash available to pay distributions is cash we receive as distributions from Discovery. As in our partnership agreement, Discovery’s limited liability company agreement, as amended, provides for the distribution of available cash on a quarterly basis, with available cash defined to mean, for each fiscal quarter, cash generated from Discovery’s business less reserves that are necessary or appropriate to provide for the conduct of its business and to comply with applicable law or any debt instrument or other agreement to which it is a party. Under Discovery’s limited liability company agreement, the amount of Discovery’s quarterly distributions, including the amount of cash reserves not distributed, is determined by the members of Discovery’s management committee representing a majority-in-interest in Discovery. We own a 60% interest in Discovery. Discovery’s limited liability agreement may only be amended with the unanimous approval of all its members.

 

Definition of Operating Surplus

 

Operating surplus for any period generally means:

 

 

Because operating surplus is a cash accounting concept, the benefit that we receive from the partial credit for general and administrative expenses and other reimbursements we receive from Williams under the omnibus agreement will be part of our operating surplus.

 

As described above, operating surplus does not reflect actual cash on hand that is available for distribution to our unitholders. For example, it includes a provision that will enable us, if we choose, to distribute as operating

surplus up to $22.8 million of cash we receive in the future from non-operating sources, such as asset sales, issuances of securities, and long-term borrowings, that would otherwise be distributed as capital surplus.

 

We define operating expenditures in our partnership agreement, and it generally means all of our expenditures, including, but not limited to, taxes, reimbursement of expenses incurred by our general partner on our behalf, repayments of working capital borrowings, debt service payments and capital expenditures (except as provided in the second bullet below), provided that operating expenditures will not include:

 

 

Capital expenditures that are operating expenses, which we also refer to as maintenance capital expenditures, are made to replace partially or fully depreciated assets, to maintain the existing operating capacity of our assets and to extend their useful lives, or other capital expenditures that are incurred in maintaining existing system volumes or our asset base. Capital expenditures made for acquisitions or capital improvements, which we also refer to as expansion capital expenditures, are made to increase operating capacity, revenues or cash flow from operations, whether through construction, acquisition, replacement or improvement. Expansion capital expenditures include contributions made by us to an entity in which we have an equity interest to be used by it for acquisitions or capital improvements. Pursuant to our partnership agreement, capital expenditures that are made in part for maintenance capital purposes and in part for expansion capital purposes will be allocated by our general partner, with the concurrence of our conflicts committee.

 

Definition of Capital Surplus

 

We also define capital surplus in our partnership agreement, and it will generally be generated only by the following, which we call “interim capital transactions”:

 

 

Characterization of Cash Distributions

 

We will treat all available cash distributed as coming from operating surplus until the sum of all available cash distributed since we began operations equals the operating surplus as of the most recent date of determination of available cash. We will treat any amount distributed in excess of operating surplus, regardless of its source, as capital surplus. We do not anticipate that we will make any distributions from capital surplus.

 

Distributions of Available Cash from Operating Surplus

 

We will make distributions of available cash from operating surplus for any quarter in the following manner:

 

 

The preceding discussion is based on the assumptions that our general partner maintains its 2% general partner interest and that we do not issue additional classes of equity securities.

Incentive Distribution Rights

 

Incentive distribution rights represent the right to receive an increasing percentage of quarterly distributions of available cash from operating surplus after the minimum quarterly distribution and the target distribution levels have been achieved. Our general partner currently holds the incentive distribution rights, but may transfer these rights separately from its general partner interest, subject to restrictions in the partnership agreement.

 

If for any quarter:

 

 

then, subject to the amendments to our partnership agreement described below, we will distribute any additional available cash from operating surplus for that quarter among the unitholders and our general partner in the following manner:

 

 

In each case, the amount of the target distribution set forth above is exclusive of any distributions to common unitholders to eliminate any cumulative arrearages in payment of the minimum quarterly distribution. The percentage interests set forth above for our general partner assumes that our general partner maintains its 2% general partner interest, that our general partner has not transferred the incentive distribution rights and that we do not issue additional classes of equity securities.

 

On April 16, 2009, we amended our partnership agreement to eliminate any distributions of available cash to our general partner, as the holder of the incentive distribution rights, with respect to each quarter ending in 2009. Accordingly, for 2009, the pro rata percentage of available cash from operating surplus that has been, or will be, distributed to our general partner under each of the second, third and fourth bullets above is 2%.

 

Percentage Allocations of Available Cash from Operating Surplus

 

The following table illustrates the percentage allocations of the additional available cash from operating surplus among the unitholders and our general partner up to the various target distribution levels. The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of the unitholders and our general partner in any available cash from operating surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution Target Amount,” until available cash from operating surplus we distribute reaches the next target distribution level, if any. The percentage interests shown for the unitholders and our general partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests set forth below for our general partner include its 2% general partner interest and assume our general partner has contributed additional capital to maintain

its 2% general partner interest, that our general partner has not transferred the incentive distribution rights and that we do not issue additional classes of equity securities.

 

 

Distributions from Capital Surplus

 

How Distributions from Capital Surplus Will Be Made

 

We will make distributions of available cash from capital surplus, if any, in the following manner:

 

 

The preceding discussion is based on the assumption that our general partner maintains its 2% general partner interest and that we do not issue additional classes of equity securities.

 

Effect of a Distribution from Capital Surplus

 

The partnership agreement treats a distribution of capital surplus as the repayment of the initial unit price from our initial public offering, which is a return of capital. The initial public offering price less any distributions of capital surplus per unit is referred to as the “unrecovered initial unit price.” Each time a distribution of capital surplus is made, the minimum quarterly distribution and the target distribution levels will be reduced in the same proportion as the corresponding reduction in the unrecovered initial unit price. Because distributions of capital surplus will reduce the minimum quarterly distribution, after any of these distributions are made it may be easier for our general partner to receive incentive distributions. However, any distribution of capital surplus before the unrecovered initial unit price is reduced to zero cannot be applied to the payment of the minimum quarterly distribution or any arrearages.

 

Once we distribute capital surplus on a unit in an amount equal to the initial unit price, we will reduce the minimum quarterly distribution and the target distribution levels to zero. We will then make all future distributions from operating surplus, with 50% being paid to the holders of units and 50% to our general partner. The percentage interests shown for our general partner assume that our general partner maintains its 2% general partner interest, that our general partner has not transferred the incentive distribution rights and that we do not issue additional classes of equity securities.

 

Adjustment to the Minimum Quarterly Distribution and Target Distribution Levels

 

In addition to adjusting the minimum quarterly distribution and target distribution levels to reflect a distribution of capital surplus, if we combine our units into fewer units or subdivide our units into a greater number of units, we will proportionately adjust:

 

 

 

For example, if a two-for-one split of the common units should occur, the minimum quarterly distribution, the target distribution levels and the unrecovered initial unit price would each be reduced to 50% of its initial level. We will not make any adjustment by reason of the issuance of additional units for cash or property.

 

In addition, if legislation is enacted or if existing law is modified or interpreted by a governmental taxing authority so that we become taxable as a corporation or otherwise subject to taxation as an entity for federal, state or local income tax purposes, we will reduce the minimum quarterly distribution and the target distribution levels for each quarter by multiplying each distribution level by a fraction, the numerator of which is available cash for that quarter and the denominator of which is the sum of available cash for that quarter plus our general partner’s estimate of our aggregate liability for the quarter for such income taxes payable by reason of such legislation or interpretation. To the extent that the actual tax liability differs from the estimated tax liability for any quarter, the difference will be accounted for in subsequent quarters.

 

Distributions of Cash Upon Liquidation

 

Overview

 

If we dissolve in accordance with the partnership agreement, we will sell or otherwise dispose of our assets in a process called liquidation. We will first apply the proceeds of liquidation to the payment of our creditors. We will distribute any remaining proceeds to the unitholders and our general partner, in accordance with their capital account balances, as adjusted to reflect any gain or loss upon the sale or other disposition of our assets in liquidation.

 

Manner of Adjustments for Gain

 

The manner of the adjustment for gain is set forth in the partnership agreement. If we liquidate, we will allocate any gain to the partners in the following manner:

 

 

(1) the unrecovered initial unit price for that common unit; and

 

(2) the amount of the minimum quarterly distribution for the quarter during which our liquidation occurs;

 

 

(1) the sum of the excess of the first target distribution per unit over the minimum quarterly distribution per unit for each quarter of our existence; less

 

(2) the cumulative amount per unit of any distributions of available cash from operating surplus in excess of the minimum quarterly distribution per unit that we distributed 98% to the unitholders, pro rata, and 2% to our general partner, for each quarter of our existence;

 

 

(1) the sum of the excess of the second target distribution per unit over the first target distribution per unit for each quarter of our existence; less

 

(2) the cumulative amount per unit of any distributions of available cash from operating surplus in excess of the first target distribution per unit that we distributed 85% to the unitholders, pro rata, and 15% to our general partner for each quarter of our existence;

 

(1) the sum of the excess of the third target distribution per unit over the second target distribution per unit for each quarter of our existence; less

 

(2) the cumulative amount per unit of any distributions of available cash from operating surplus in excess of the second target distribution per unit that we distributed 75% to the unitholders, pro rata, and 25% to our general partner for each quarter of our existence; and

 

 

The percentage interests set forth above for our general partner assume that our general partner maintains its 2% general partner interest, that our general partner has not transferred the incentive distribution rights and that we do not issue additional classes of equity securities.

 

Manner of Adjustments for Losses

 

If we liquidate, we will generally allocate any loss to our general partner and the unitholders in the following manner:

 

 

The percentage interests set forth above for our general partner assume that our general partner maintains its 2% general partner interest, that our general partner has not transferred the incentive distribution rights and that we do not issue additional classes of equity securities.

 

Adjustments to Capital Accounts

 

We will make adjustments to capital accounts upon the issuance of additional units. In doing so, we will allocate any unrealized and, for tax purposes, unrecognized gain or loss resulting from the adjustments to the unitholders and our general partner in the same manner as we allocate gain or loss upon liquidation. In the event that we make positive adjustments to the capital accounts upon the issuance of additional units, we will allocate any later negative adjustments to the capital accounts resulting from the issuance of additional units or upon our liquidation in a manner which results, to the extent possible, in our general partner’s capital account balances equaling the amount which they would have been if no earlier positive adjustments to the capital accounts had been made.

 

The following is a summary of the material provisions of our partnership agreement. Our partnership agreement is incorporated by reference as an exhibit to the registration statement of which this prospectus constitutes a part. We will provide prospective investors with a copy of this agreement upon request at no charge.

 

We summarize the following provisions of our partnership agreement elsewhere in this prospectus:

 

 

Organization and Duration

 

We were organized on February 28, 2005 and have a perpetual existence.

Purpose

 

Our purpose under the partnership agreement is limited to serving as the sole member of our operating company and engaging in any business activities that may be engaged in by our operating company and its subsidiaries or that are approved by our general partner. The limited liability company agreement of our operating company provides that it may, directly or indirectly, engage in:

 

(1) its operations as conducted immediately before our initial public offering;

 

(2) any other activity approved by our general partner but only to the extent that our general partner determines that, as of the date of the acquisition or commencement of the activity, the activity generates “qualifying income” as this term is defined in Section 7704 of the Internal Revenue Code; or

 

(3) any activity that enhances the operations of an activity that is described in (1) or (2) above.

 

Although our general partner has the ability to cause us, our operating company or its subsidiaries to engage in activities other than gathering, transporting, processing, and treating natural gas and the fractionating and storing of NGLs, our general partner has no current plans to do so and may decline to do so free of any fiduciary duty or obligation whatsoever to us or the limited partners, including any duty to act in good faith or in the best interests of us or the limited partners. Our general partner is authorized in general to perform all acts it determines to be necessary or appropriate to carry out our purposes and to conduct our business.

 

Power of Attorney

 

Each limited partner and each person who acquires a unit from a unitholder, by accepting the common unit, automatically grants to our general partner and, if appointed, a liquidator, a power of attorney to, among other things, execute and file documents required for our qualification, continuance or dissolution. The power of attorney also grants our general partner the authority to amend, and to make consents and waivers under, our partnership agreement. Please read “— Amendment of the Partnership Agreement” below.

 

Capital Contributions

 

Unitholders are not obligated to make additional capital contributions, except as described below under “— Limited Liability.”

 

Limited Liability

 

Participation in the Control of Our Partnership

 

Assuming that a limited partner does not participate in the control of our business within the meaning of the Delaware Act and that he otherwise acts in conformity with the provisions of our partnership agreement, his liability under the Delaware Act will be limited, subject to possible exceptions, to the amount of capital he is obligated to contribute to us for his common units plus his share of any undistributed profits and assets. If it were determined, however, that the right, or exercise of the right, by the limited partners as a group:

 

 

constituted “participation in the control” of our business for the purposes of the Delaware Act, then the limited partners could be held personally liable for our obligations under the laws of Delaware, to the same extent as our general partner. This liability would extend to persons who transact business with us who reasonably believe that the limited partner is a general partner. Neither our partnership agreement nor the Delaware Act specifically provides for legal recourse against our general partner if a limited partner were to lose limited liability through any fault of our general partner. While this does not mean that a limited partner could not seek legal recourse, we know of no precedent for such a claim in Delaware case law.

Unlawful Partnership Distribution

 

Under the Delaware Act, a limited partnership may not make a distribution to a partner if, after the distribution, all liabilities of the limited partnership, other than liabilities to partners on account of their partnership interests and liabilities for which the recourse of creditors is limited to specific property of the partnership, would exceed the fair value of the assets of the limited partnership. For the purpose of determining the fair value of the assets of a limited partnership, the Delaware Act provides that the fair value of property subject to liability for which recourse of creditors is limited shall be included in the assets of the limited partnership only to the extent that the fair value of that property exceeds the nonrecourse liability. The Delaware Act provides that a limited partner who receives a distribution and knew at the time of the distribution that the distribution was in violation of the Delaware Act shall be liable to the limited partnership for the amount of the distribution for three years. Under the Delaware Act, a substituted limited partner of a limited partnership is liable for the obligations of his assignor to make contributions to the partnership, except that such person is not obligated for liabilities unknown to him at the time he became a limited partner and that could not be ascertained from the partnership agreement.

 

Failure to Comply with the Limited Liability Provisions of Jurisdictions in Which We Do Business

 

Our subsidiaries may be deemed to conduct business in Kansas, Louisiana, Alabama, Colorado, New Mexico, and Wyoming. Our subsidiaries may conduct business in other states in the future. Maintenance of our limited liability may require compliance with legal requirements in the jurisdictions in which the operating company conducts business, including qualifying our subsidiaries to do business there. Limitations on the liability of limited partners for the obligations of a limited partnership have not been clearly established in many jurisdictions. If, by virtue of our membership interest in our operating company or otherwise, it were determined that we were conducting business in any state without compliance with the applicable limited partnership or limited liability company statute, or that the right or exercise of the right by the limited partners as a group to remove or replace our general partner, to approve some amendments to our partnership agreement, or to take other action under the partnership agreement constituted “participation in the control” of our business for purposes of the statutes of any relevant jurisdiction, then the limited partners could be held personally liable for our obligations under the law of that jurisdiction to the same extent as our general partner under the circumstances. We will operate in a manner that our general partner considers reasonable and necessary or appropriate to preserve the limited liability of the limited partners.

 

Voting Rights

 

The following matters require the unitholder vote specified below. Matters requiring the approval of a “unit majority” require the approval of a majority of the common units.

 

In voting their common units, our general partner and its affiliates have no fiduciary duty or obligation whatsoever to us or the limited partners, including any duty to act in good faith or in the best interests of us and the limited partners.

 

 

 

Issuance of Additional Securities

 

Our partnership agreement authorizes us to issue an unlimited number of additional partnership securities and rights to buy partnership securities, subject to the limitations imposed by the New York Stock Exchange, for the consideration and on the terms and conditions determined by our general partner without the approval of the unitholders.

 

It is possible that we will fund acquisitions through the issuance of additional common units or other equity securities. Holders of any additional common units we issue will be entitled to share equally with the then-existing holders of common units in our distributions of available cash. In addition, the issuance of additional partnership interests may dilute the value of the interests of the then-existing holders of common units in our net assets.

In accordance with Delaware law and the provisions of our partnership agreement, we may also issue additional partnership securities that, as determined by our general partner, may have special voting rights to which the common units are not entitled. In addition, our partnership agreement does not prohibit the issuance by our subsidiaries of equity securities, which may effectively rank senior to our common units.

 

Upon issuance of additional partnership securities, our general partner will have the right, but not the obligation, to make additional capital contributions to the extent necessary to maintain its 2% general partner interest in us. Our general partner’s 2% interest in us will be reduced if we issue additional units in the future and our general partner does not contribute a proportionate amount of capital to us to maintain its 2% general partner interest. Moreover, our general partner will have the right, which it may from time to time assign in whole or in part to any of its affiliates, to purchase common units or other equity securities whenever, and on the same terms that, we issue those securities to persons other than our general partner and its affiliates, to the extent necessary to maintain its and its affiliates’ percentage interest, including its interest represented by common units that existed immediately prior to each issuance. The holders of common units will not have preemptive rights to acquire additional common units or other partnership securities.

 

Amendment of the Partnership Agreement

 

General

 

Amendments to our partnership agreement may be proposed only by or with the consent of our general partner. However, our general partner will have no duty or obligation to propose any amendment and may decline to do so free of any fiduciary duty or obligation whatsoever to us or the limited partners, including any duty to act in good faith or in the best interests of us or the limited partners. In order to adopt a proposed amendment, other than the amendments discussed below, our general partner must seek written approval of the holders of the number of units required to approve the amendment or call a meeting of the limited partners to consider and vote upon the proposed amendment. Except as described below, an amendment must be approved by a unit majority.

 

Prohibited Amendments

 

No amendment may be made that would:

 

(1) enlarge the obligations of any limited partner without its consent, unless approved by at least a majority of the type or class of limited partner interests so affected; or

 

(2) enlarge the obligations of, restrict in any way any action by or rights of, or reduce in any way the amounts distributable, reimbursable or otherwise payable by us to our general partner or any of its affiliates without the consent of our general partner, which may be given or withheld at its option.

 

The provision of our partnership agreement preventing the amendments having the effects described in clauses (1) or (2) above can be amended upon the approval of the holders of at least 90% of the outstanding units voting together as a single class (including units owned by our general partner and its affiliates). As of October 28, 2009, our general partner and its affiliates owned approximately 21.6% of the outstanding units.

 

No Unitholder Approval

 

Our general partner may generally make amendments to our partnership agreement without the approval of any limited partner to reflect:

 

(1) a change in our name, the location of our principal place of business, our registered agent or our registered office;

 

(2) the admission, substitution, withdrawal or removal of partners in accordance with our partnership agreement;

 

(3) a change that our general partner determines to be necessary or appropriate for us to qualify or to continue our qualification as a limited partnership or a partnership in which the limited partners have limited liability under the laws of any state or to ensure that neither we, the operating company nor its subsidiaries will

be treated as an association taxable as a corporation or otherwise taxed as an entity for federal income tax purposes;

 

(4) an amendment that is necessary, in the opinion of our counsel, to prevent us or our general partner or its directors, officers, agents, or trustees from in any manner being subjected to the provisions of the Investment Company Act of 1940, the Investment Advisors Act of 1940 or “plan asset” regulations adopted under ERISA whether or not substantially similar to plan asset regulations currently applied or proposed;

 

(5) subject to the limitations on the issuance of additional partnership securities described above, an amendment that our general partner determines to be necessary or appropriate for the authorization of additional partnership securities or rights to acquire partnership securities;

 

(6) any amendment expressly permitted in our partnership agreement to be made by our general partner acting alone;

 

(7) an amendment effected, necessitated or contemplated by a merger agreement that has been approved under the terms of our partnership agreement;

 

(8) any amendment that our general partner determines to be necessary or appropriate for the formation by us of, or our investment in, any corporation, partnership or other entity, as otherwise permitted by our partnership agreement;

 

(9) a change in our fiscal year or taxable year and related changes;

 

(10) certain mergers or conveyances as set forth in our partnership agreement; or

 

(11) any other amendments substantially similar to any of the matters described in clauses (1) through (10) above.

 

In addition, our general partner may make amendments to our partnership agreement without the approval of any limited partner if our general partner determines that those amendments:

 

 

Opinion of Counsel and Unitholder Approval

 

Our general partner will not be required to obtain an opinion of counsel that an amendment will not result in a loss of limited liability to the limited partners or result in our being taxed as an entity for federal income tax purposes in connection with any of the amendments described above under “— No Unitholder Approval.” No other amendments to our partnership agreement will become effective without the approval of holders of at least 90% of the outstanding units voting as a single class unless we obtain an opinion of counsel to the effect that the amendment will not affect the limited liability under applicable law of any of our limited partners.

 

In addition to the above restrictions, any amendment that would have a material adverse effect on the rights or preferences of any type or class of outstanding units in relation to other classes of units will require the approval of at least a majority of the type or class of units so affected. Any amendment that reduces the voting percentage required

to take any action must be approved by the affirmative vote of limited partners whose aggregate outstanding units constitute not less than the voting requirement sought to be reduced.

 

Action Relating to the Operating Company

 

Without the approval of the holders of units representing a unit majority, our general partner is prohibited from consenting on our behalf, as the sole member of the operating company, to any amendment to the limited liability company agreement of the operating company or taking any action on our behalf permitted to be taken by a member of the operating company, in each case, that would adversely affect our limited partners (or any particular class of limited partners) in any material respect.

 

Merger, Sale or Other Disposition of Assets

 

A merger or consolidation of us requires the consent of our general partner. However, our general partner will have no duty or obligation to consent to any merger or consolidation and may decline to do so free of any fiduciary duty or obligation whatsoever to us or the limited partners, including any duty to act in good faith or in the best interests of us or the limited partners. In addition, the partnership agreement generally prohibits our general partner, without the prior approval of the holders of units representing a unit majority, from causing us to, among other things, sell, exchange or otherwise dispose of all or substantially all of our assets in a single transaction or a series of related transactions, including by way of merger, consolidation or other combination, or approving on our behalf the sale, exchange or other disposition of all or substantially all of the assets of our subsidiaries. Our general partner may, however, mortgage, pledge, hypothecate or grant a security interest in all or substantially all of our assets without that approval. Our general partner may also sell all or substantially all of our assets under a foreclosure or other realization upon those encumbrances without that approval. Finally, our general partner may consummate any merger or consolidation without the prior approval of our unitholders if our general partner has received an opinion of counsel that the merger or consolidation, as the case may be, would not result in the loss of the limited liability of to the limited partners or result in our being taxed as an entity for federal income tax purposes, we are the surviving entity in the transaction, the transaction would not result in an amendment to our partnership agreement that the could not otherwise be adopted solely by our general partner, each of our units will be an identical unit of our partnership following the transaction, and the units to be issued do not exceed 20% of our outstanding units immediately prior to the transaction.

 

If the conditions specified in our partnership agreement are satisfied, our general partner may convert us or any of our subsidiaries into a new limited liability entity or merge us or any of our subsidiaries into, or convey some or all of our assets to, a newly formed entity if the sole purpose of that merger or conveyance is to effect a mere change in our legal form into another limited liability entity. The unitholders are not entitled to dissenters’ rights of appraisal under our partnership agreement or applicable Delaware law in the event of a conversion, merger or consolidation, a sale of substantially all of our assets or any other transaction or event.

 

Termination and Dissolution

 

We will continue as a limited partnership until terminated under our partnership agreement. We will dissolve upon:

 

(1) the election of our general partner to dissolve us, if approved by the holders of units representing a unit majority;

 

(2) the entry of a decree of judicial dissolution of our partnership;

 

(3) the withdrawal or removal of our general partner or any other event that results in its ceasing to be our general partner other than by reason of a transfer of its general partner interest in accordance with our partnership agreement or withdrawal or removal following approval and admission of a successor; or

 

(4) there being no limited partners, unless we are continued without dissolution in accordance with applicable Delaware law.

Upon a dissolution under clause (3) above, the holders of a unit majority may also elect, within specific time limitations, to continue our business on the same terms and conditions described in the partnership agreement by appointing as a successor general partner an entity approved by the holders of units representing a unit majority, subject to our receipt of an opinion of counsel to the effect that:

 

 

Liquidation and Distribution of Proceeds

 

Upon our dissolution, unless we are reconstituted and continued as a new limited partnership, the liquidator authorized to wind up our affairs will, acting with all of the powers of our general partner that are necessary or appropriate, liquidate our assets and apply the proceeds of the liquidation as described in “Provisions of Our Partnership Agreement Relating to Cash Distributions — Distributions of Cash Upon Liquidation.” The liquidator may defer liquidation or distribution of our assets for a reasonable period at time or distribute assets to partners in kind if it determines that a sale would be impractical or would cause undue loss to the partners.

 

Withdrawal or Removal of Our General Partner

 

Except as described below, our general partner has agreed not to withdraw voluntarily as the general partner of our partnership prior to June 30, 2015 without obtaining the approval of the holders of at least a majority of the outstanding common units, excluding common units held by our general partner and its affiliates, and furnishing an opinion of counsel regarding limited liability and tax matters. On or after June 30, 2015, our general partner may withdraw as general partner without first obtaining approval of any unitholder by giving 90 days’ written notice, and that withdrawal will not constitute a violation of our partnership agreement. Notwithstanding the information above, our general partner may withdraw without unitholder approval upon 90 days’ notice to the limited partners if at least 50% of the outstanding common units are held or controlled by one person and its affiliates other than our general partner and its affiliates. In addition, our partnership agreement permits our general partner in some instances to sell or otherwise transfer all of its general partner interest in us without the approval of the unitholders. Please read “— Transfer of General Partner Interest” and “— Transfer of Incentive Distribution Rights” below.

 

Upon the withdrawal of our general partner under any circumstances, other than as a result of a transfer by our general partner of all or a part of its general partner interest in us, the holders of a majority of the outstanding common units may select a successor to that withdrawing general partner. If a successor is not elected, or is elected but an opinion of counsel regarding limited liability and tax matters cannot be obtained, we will be dissolved, wound up and liquidated, unless within a specified period of time after that withdrawal, the holders of a unit majority agree in writing to continue our business and to appoint a successor general partner. Please read “— Termination and Dissolution.”

 

Our general partner may not be removed unless that removal is approved by the vote of the holders of not less than 662/3% of the outstanding units, voting together as a single class, including units held by our general partner and its affiliates, and we receive an opinion of counsel regarding limited liability and tax matters. Any removal of our general partner is also subject to the approval of a successor general partner by the vote of the holders of a majority of the outstanding common units. The ownership of more than 331/3% of the outstanding units by our general partner and its affiliates would give them the practical ability to prevent the general partner’s removal. As October 28, 2009, our general partner and its affiliates owned approximately 21.6% of the outstanding units.

 

Our partnership agreement also provides that if our general partner is removed as our general partner under circumstances where cause does not exist and units held by our general partner and its affiliates are not voted in favor of that removal, our general partner will have the right to convert its general partner interest and its incentive distribution rights into common units or to receive cash in exchange for those interests based on the fair market value of the interests at the time.

In the event of removal of a general partner under circumstances where cause exists or withdrawal of a general partner where that withdrawal violates our partnership agreement, a successor general partner will have the option to purchase the general partner interest and incentive distribution rights of the departing general partner for a cash payment equal to the fair market value of those interests. Under all other circumstances where a general partner withdraws or is removed by the limited partners, the departing general partner will have the option to require the successor general partner to purchase the general partner interest of the departing general partner and its incentive distribution rights for their fair market value. In each case, this fair market value will be determined by agreement between the departing general partner and the successor general partner. If no agreement is reached, an independent investment banking firm or other independent expert selected by the departing general partner and the successor general partner will determine the fair market value. Or, if the departing general partner and the successor general partner cannot agree upon an expert, then an expert chosen by agreement of the experts selected by each of them will determine the fair market value.

 

If the option described above is not exercised by either the departing general partner or the successor general partner, the departing general partner’s general partner interest and its incentive distribution rights will automatically convert into common units equal to the fair market value of those interests as determined by an investment banking firm or other independent expert selected in the manner described in the preceding paragraph.

 

In addition, we will be required to reimburse the departing general partner for all amounts due the departing general partner, including, without limitation, all employee-related liabilities, including severance liabilities, incurred for the termination of any employees employed by the departing general partner or its affiliates for our benefit.

 

Transfer of General Partner Interest

 

Except for transfer by our general partner of all, but not less than all, of its general partner interest in us to:

 

 

our general partner may not transfer all or any part of its general partner interest in us to another person prior to June 30, 2015 without the approval of the holders of at least a majority of the outstanding common units, excluding common units held by our general partner and its affiliates. As a condition of this transfer, the transferee must, among other things, assume the rights and duties of our general partner, agree to be bound by the provisions of our partnership agreement, and furnish an opinion of counsel regarding limited liability and tax matters.

 

Our general partner and its affiliates may at any time transfer units to one or more persons without unitholder approval.

 

Transfer of Incentive Distribution Rights

 

Our general partner or its affiliates or a subsequent holder may transfer its incentive distribution rights to an affiliate of the holder (other than an individual) or another entity as part of the merger or consolidation of such holder with or into another entity, the sale of all the ownership interests in the holder or the sale of all or substantially all of its assets to, that entity without the prior approval of the unitholders. Prior to June 30, 2015, other transfers of the incentive distribution rights will require the affirmative vote of holders of a majority of the outstanding common units (excluding common units held by our general partner and its affiliates). On or after June 30, 2015, the incentive distribution rights will be freely transferable.

 

Transfer of Ownership Interests in Our General Partner

 

At any time, the members of our general partner may sell or transfer all or part of their membership interests in our general partner to an affiliate or a third party without the approval of our unitholders.

Change of Management Provisions

 

Our partnership agreement contains specific provisions that are intended to discourage a person or group from attempting to remove Williams Partners GP LLC as our general partner or otherwise change our management. If any person or group other than our general partner and its affiliates acquires beneficial ownership of 20% or more of any class of units, that person or group loses voting rights on all of its units. This loss of voting rights does not apply to any person or group that acquires the units from our general partner or its affiliates and any transferees of that person or group approved by our general partner or to any person or group who acquires the units with the prior approval of the board of directors of our general partner.

 

Our partnership agreement also provides that if our general partner is removed under circumstances where cause does not exist and units held by our general partner and its affiliates are not voted in favor of that removal, our general partner will have the right to convert its general partner interest and its incentive distribution rights into common units or to receive cash in exchange for those interests.

 

Limited Call Right

 

If at any time our general partner and its affiliates hold more than 80% of the then-issued and outstanding partnership securities of any class, our general partner will have the right, but not the obligation, which it may assign in whole or in part to any of its affiliates or to us, to acquire all, but not less than all, of the remaining partnership securities of the class held by unaffiliated persons as of a record date to be selected by our general partner, on at least 10 but not more than 60 days notice. The purchase price in the event of this purchase is the greater of:

 

(1) the highest price paid by either of our general partner or any of its affiliates for any partnership securities of the class purchased within the 90 days preceding the date on which our general partner first mails notice of its election to purchase those partnership securities; and

 

(2) the current market price as of the date three days before the date the notice is mailed.

 

As a result of our general partner’s right to purchase outstanding partnership securities, a holder of partnership securities may have his partnership securities purchased at an undesirable time or price. Our partnership agreement provides that the resolution of any conflict of interest that is fair and reasonable will not be a breach of the partnership agreement. Our general partner may, but it is not obligated to, submit the conflict of interest represented by the exercise of the limited call right to the conflicts committee for approval or seek a fairness opinion from an investment banker. If our general partner exercises its limited call right, it will make a determination at the time, based on the facts and circumstances, and upon the advice of counsel, as to the appropriate method of determining the fairness and reasonableness of the transaction. Our general partner is not obligated to obtain a fairness opinion regarding the value of the common units to be repurchased by it upon exercise of the limited call right.

 

There is no restriction in our partnership agreement that prevents our general partner from issuing additional common units and exercising its call right. If our general partner exercised its limited call right, the effect would be to take us private and, if the units were subsequently deregistered, we would no longer be subject to the reporting requirements of the Exchange Act.

 

The tax consequences to a unitholder of the exercise of this call right are the same as a sale by that unitholder of his common units in the market. Please read “Material Tax Considerations — Disposition of Common Units.”

 

Meetings; Voting

 

Except as described below regarding a person or group owning 20% or more of any class of units then outstanding, unitholders who are record holders of units on the record date will be entitled to notice of, and to vote at, meetings of our limited partners and to act upon matters for which approvals may be solicited. In the case of common units held by our general partner on behalf of non-citizen assignees, our general partner will distribute the votes on those common units in the same ratios as the votes of limited partners on other units are cast.

 

Our general partner does not anticipate that any meeting of unitholders will be called in the foreseeable future. Any action that is required or permitted to be taken by the unitholders may be taken either at a meeting of the unitholders or without a meeting if consents in writing describing the action so taken are signed by holders of the

number of units necessary to authorize or take that action at a meeting. Meetings of the unitholders may be called by our general partner or by unitholders owning at least 20% of the outstanding units of the class for which a meeting is proposed. Unitholders may vote either in person or by proxy at meetings. The holders of a majority of the outstanding units of the class or classes for which a meeting has been called, represented in person or by proxy, will constitute a quorum unless any action by the unitholders requires approval by holders of a greater percentage of the units, in which case the quorum will be the greater percentage.

 

Each record holder of a unit has a vote according to his percentage interest in us, although additional limited partner interests having special voting rights could be issued. Please read “— Issuance of Additional Securities” above. However, if at any time any person or group, other than our general partner and its affiliates, or a direct or subsequently approved transferee of our general partner or its affiliates, or a person or group who acquire units with the prior approval of the board of our general partner acquires, in the aggregate, beneficial ownership of 20% or more of any class of units then outstanding, that person or group will lose voting rights on all of its units and the units may not be voted on any matter and will not be considered to be outstanding when sending notices of a meeting of unitholders, calculating required votes, determining the presence of a quorum or for other similar purposes. Common units held in nominee or street name account will be voted by the broker or other nominee in accordance with the instruction of the beneficial owner unless the arrangement between the beneficial owner and his nominee provides otherwise.

 

Any notice, demand, request, report or proxy material required or permitted to be given or made to record holders of common units under our partnership agreement will be delivered to the record holder by us or by the transfer agent.

 

Status as Limited Partner

 

By transfer of any common units in accordance with our partnership agreement, each transferee of common units shall be admitted as a limited partner with respect to the common units transferred when such transfer is reflected in our books and records.

 

Except as described above under “— Limited Liability” above, the common units will be fully paid, and unitholders will not be required to make additional contributions.

 

Non-Citizen Assignees; Redemption

 

If we are or become subject to federal, state or local laws or regulations that, in the determination of our general partner, create a substantial risk of cancellation or forfeiture of any property in which we have an interest because of the nationality, citizenship or other related status of any limited partner we may redeem the units held by the limited partner at their current market price, in accordance with the procedures set forth in our partnership agreement. In order to avoid any cancellation or forfeiture, our general partner may require each limited partner to furnish information about his nationality, citizenship or related status. If a limited partner or assignee fails to furnish information about his nationality, citizenship or other related status within 30 days after a request for the information or our general partner determines after receipt of the information that the limited partner is not an eligible citizen, the limited partner may be treated as a non-citizen assignee. A non-citizen assignee is entitled to an interest equivalent to that of a limited partner for the right to share in allocations and distributions from us, including liquidating distributions. A non-citizen assignee does not have the right to direct the voting of his units and may not receive distributions in kind upon our liquidation.

 

Indemnification

 

Under our partnership agreement, in most circumstances, we will indemnify the following persons, to the fullest extent permitted by law, from and against all losses, claims, damages or similar events:

 

(1) our general partner;

 

(2) any departing general partner;

(3) any person who is or was an affiliate of our general partner (including Williams and its subsidiaries) or any departing general partner;

 

(4) any person who is or was an officer, director, member, partner, fiduciary or trustee of any entity described in (1), (2) or (3) above;

 

(5) any person who is or was serving as an officer, director, member, partner, fiduciary or trustee of another person at the request of our general partner or any departing general partner; and

 

(6) any person designated by our general partner.

 

Any indemnification under these provisions will only be out of our assets. Unless it otherwise agrees, our general partner will not be personally liable for, or have any obligation to contribute or loan funds or assets to us to enable us to effectuate, indemnification. We may purchase insurance against liabilities asserted against and expenses incurred by persons for our activities, regardless of whether we would have the power to indemnify the person against liabilities under the partnership agreement.

 

Books and Reports

 

Our general partner is required to keep appropriate books of our business at our principal offices. The books are maintained for both tax and financial reporting purposes on an accrual basis. For tax and financial reporting purposes, our fiscal year is the calendar year.

 

We will furnish or make available to record holders of common units, within 120 days after the close of each fiscal year, an annual report containing audited financial statements and a report on those financial statements by our independent registered public accounting firm or make such reports available on the SEC’s EDGAR System. Except for our fourth quarter, we will also furnish or make available on EDGAR summary financial information within 90 days after the close of each quarter.

 

We will furnish each record holder of a unit with information reasonably required for tax reporting purposes within 90 days after the close of each calendar year. This information is expected to be furnished in summary form so that some complex calculations normally required of partners can be avoided. Our ability to furnish this summary information to unitholders will depend on the cooperation of unitholders in supplying us with specific information. Every unitholder will receive information to assist him in determining his federal and state tax liability and filing his federal and state income tax returns, regardless of whether he supplies us with information.

 

Right to Inspect Our Books and Records

 

Our partnership agreement provides that a limited partner can, for a purpose reasonably related to his interest as a limited partner, upon reasonable demand stating the purpose of such demand and at his own expense, obtain:

 

(1) a current list of the name and last known address of each partner;

 

(2) a copy of our tax returns;

 

(3) information as to the amount of cash, and a description and statement of the net agreed value of any other property or services, contributed or to be contributed by each partner and the date on which each became a partner;

 

(4) copies of our partnership agreement, the certificate of limited partnership of the partnership, related amendments and powers of attorney under which they have been executed;

 

(5) information regarding the status of our business and financial condition; and

 

(6) any other information regarding our affairs as is just and reasonable.

 

Our general partner may, and intends to, keep confidential from the limited partners trade secrets or other information the disclosure of which our general partner believes in good faith is not in our best interests, could damage us or our business or that we are required by law or by agreements with third parties to keep confidential.

Registration Rights

 

Under our partnership agreement, we have agreed to register for resale under the Securities Act and applicable state securities laws any common units or other partnership securities proposed to be sold by our general partner or any of its affiliates or their assignees if an exemption from the registration requirements is not otherwise available. These registration rights continue for two years following any withdrawal or removal of Williams Partners GP LLC as our general partner. We are obligated to pay all expenses incidental to the registration, excluding underwriting discounts and commissions.

 

Fiduciary and Other Duties

 

Our general partner is accountable to us and our unitholders and has fiduciary, contractual, common law and statutory duties to us. Fiduciary duties owed to us by our general partner are prescribed by law and the partnership agreement. The Delaware Revised Uniform Limited Partnership Act, (“Delaware Act”) provides that Delaware limited partnerships may, in their partnership agreements, expand, restrict or eliminate the duties (including fiduciary duties) otherwise owed by a general partner to limited partners and the partnership.

 

Our partnership agreement contains various provisions modifying and restricting the duties that might otherwise be owed by our general partner. We have adopted these provisions to allow our general partner or its affiliates to engage in transactions with us that otherwise might be prohibited by state law fiduciary standards and to take into account the interests of other parties in addition to our interests when resolving conflicts of interest. We believe this is appropriate and necessary because the board of directors of our general partner has fiduciary duties to manage our general partner in a manner beneficial both to its owner, Williams, as well as to you. Without these modifications, the general partner’s ability to make decisions involving conflicts of interests would be restricted. The modifications to the fiduciary standards benefit our general partner by enabling it to take into consideration all parties involved in the proposed action. These modifications also strengthen the ability of our general partner to attract and retain experienced and capable directors. These modifications represent a detriment to the common unitholders because they restrict the remedies available to unitholders for actions that, without those limitations, might constitute breaches of fiduciary duty, as described below, and permit our general partner to take into account the interests of third parties in addition to our interests when resolving conflicts of interest. The following is a summary of:

 

 

 

In order to become one of our limited partners, a common unitholder is required to agree to be bound by the provisions in the partnership agreement, including the provisions discussed above. Please read “Description of the Common Units — Transfer of Common Units.” This is in accordance with the policy of the Delaware Act favoring the principle of freedom of contract and the enforceability of partnership agreements. The failure of a limited partner to sign our partnership agreement does not render the partnership agreement unenforceable against that person.

 

Under the partnership agreement, we must indemnify our general partner and its officers, directors and managers, to the fullest extent permitted by law, against liabilities, costs and expenses incurred by our general partner or these other persons. We must provide this indemnification unless there has been a final and non- appealable judgment by a court of competent jurisdiction determining that these persons acted in bad faith or engaged in fraud or willful misconduct. We also must provide this indemnification for criminal proceedings unless our general partner or these other persons acted with knowledge that their conduct was unlawful. Thus, our general partner could be indemnified for its negligent acts if it meets the requirements set forth above. To the extent that these provisions purport to include indemnification for liabilities arising under the Securities Act, in the opinion of the SEC such indemnification is contrary to public policy and therefore unenforceable. If you have questions regarding the fiduciary duties of our general partner please read “The Partnership Agreement — Indemnification.”

 

This section is a discussion of the material tax considerations that may be relevant to prospective unitholders who are individual citizens or residents of the United States and, unless otherwise noted in the following discussion, is the opinion of Andrews Kurth LLP, counsel to our general partner and us, insofar as it relates to matters of United States federal income tax law and legal conclusions with respect to those matters. This section is based upon current provisions of the Internal Revenue Code of 1986, as amended (“Internal Revenue Code”), existing and proposed regulations and current administrative rulings and court decisions, all of which are subject to change. Later changes in these authorities may cause the tax consequences to vary substantially from the consequences described below. Unless the context otherwise requires, references in this section to “us” or “we” are references to Williams Partners L.P. and our operating company.

 

The following discussion does not address all federal income tax matters affecting us or the unitholders. Moreover, the discussion focuses on unitholders who are individual citizens or residents of the United States and has only limited application to corporations, estates, trusts, nonresident aliens or other unitholders subject to specialized tax treatment, such as tax-exempt institutions, foreign persons, individual retirement accounts (IRAs), real estate investment trusts (REITs), employee benefit plans or mutual funds. Accordingly, we urge each prospective unitholder to consult, and depend on, his own tax advisor in analyzing the federal, state, local and foreign tax consequences particular to him of the ownership or disposition of the common units.

 

No ruling has been or will be requested from the IRS regarding any matter affecting us or prospective unitholders. Instead, we will rely on opinions and advice of Andrews Kurth LLP. Unlike a ruling, an opinion of counsel represents only that counsel’s best legal judgment and does not bind the IRS or the courts. Accordingly, the opinions and statements made in this discussion may not be sustained by a court if contested by the IRS. Any contest

of this sort with the IRS may materially and adversely impact the market for the common units and the prices at which the common units trade. In addition, the costs of any contest with the IRS, principally legal, accounting and related fees, will result in a reduction in cash available for distribution to our unitholders and our general partner and thus will be borne indirectly by our unitholders and our general partner. Furthermore, the tax treatment of us, or of an investment in us, may be significantly modified by future legislative or administrative changes or court decisions. Any modifications may or may not be retroactively applied.

 

All statements as to matters of law and legal conclusions, but not as to factual matters, contained in this section, unless otherwise noted, are the opinion of Andrews Kurth LLP and are based on the accuracy of the representations made by us and our general partner.

 

For the reasons described below, Andrews Kurth LLP has not rendered an opinion with respect to the following specific federal income tax issues:

 

 

Partnership Status

 

A partnership is not a taxable entity and incurs no federal income tax liability. Instead, each partner of a partnership is required to take into account his share of items of income, gain, loss and deduction of the partnership in computing his federal income tax liability, regardless of whether cash distributions are made to him by the partnership. Distributions by a partnership to a partner are generally not taxable to the partner unless the amount of cash distributed is in excess of the partner’s adjusted basis in his partnership interest.

 

Section 7704 of the Internal Revenue Code provides that publicly traded partnerships will, as a general rule, be taxed as corporations. However, an exception, referred to as the “Qualifying Income Exception,” exists with respect to publicly traded partnerships of which 90% or more of the gross income for every taxable year consists of “qualifying income.” Qualifying income includes income and gains derived from the transportation, storage and processing of crude oil, natural gas and products thereof. Other types of qualifying income include interest (other than from a financial business), dividends, gains from the sale of real property and gains from the sale or other disposition of capital assets held for the production of income that otherwise constitutes qualifying income. We estimate that less than 3% of our current gross income is not qualifying income; however, this estimate could change from time to time. Based on and subject to this estimate, the factual representations made by us and our general partner and a review of the applicable legal authorities, Andrews Kurth LLP is of the opinion that at least 90% of our current gross income constitutes qualifying income. The portion of our income that is qualifying income can change from time to time.

 

No ruling has been or will be sought from the IRS and the IRS has made no determination as to our status for federal income tax purposes or whether our operations generate “qualifying income” under Section 7704 of the Internal Revenue Code. Instead, we will rely on the opinion of Andrews Kurth LLP that, based upon the Internal Revenue Code, its regulations, published revenue rulings and court decisions and the representations described below, we will be classified as a partnership and our operating company will be disregarded as an entity separate from us for federal income tax purposes.

 

In rendering its opinion, Andrews Kurth LLP has relied on factual representations made by us and our general partner. The representations made by us and our general partner upon which Andrews Kurth LLP has relied include:

 

 

 

If we fail to meet the Qualifying Income Exception, other than a failure that is determined by the IRS to be inadvertent and that is cured within a reasonable time after discovery, we will be treated as if we had transferred all of our assets, subject to liabilities, to a newly formed corporation, on the first day of the year in which we fail to meet the Qualifying Income Exception, in return for stock in that corporation, and then distributed that stock to the unitholders in liquidation of their interests in us. This deemed contribution and liquidation would be tax-free to unitholders and us so long as we, at that time, do not have liabilities in excess of the tax basis of our assets. Thereafter, we would be treated as a corporation for federal income tax purposes.

 

If we were taxable as a corporation in any taxable year, either as a result of a failure to meet the Qualifying Income Exception or otherwise, our items of income, gain, loss and deduction would be reflected only on our tax return rather than being passed through to the unitholders, and our net income would be taxed to us at corporate rates. In addition, any distribution made by us to a unitholder would be treated as either taxable dividend income, to the extent of our current or accumulated earnings and profits, or, in the absence of earnings and profits, a nontaxable return of capital, to the extent of the unitholder’s tax basis in his common units, or taxable capital gain, after the unitholder’s tax basis in his common units is reduced to zero. Accordingly, taxation as a corporation would result in a material reduction in a unitholder’s cash flow and after-tax return and thus would likely result in a substantial reduction of the value of the units.

 

The discussion below is based on Andrews Kurth LLP’s opinion that we will be classified as a partnership for federal income tax purposes.

 

Limited Partner Status

 

Unitholders who have become limited partners of Williams Partners L.P. will be treated as partners of Williams Partners L.P. for federal income tax purposes. Also, unitholders whose common units are held in street name or by a nominee and who have the right to direct the nominee in the exercise of all substantive rights attendant to the ownership of their common units will be treated as partners of Williams Partners L.P. for federal income tax purposes.

 

A beneficial owner of common units whose units have been transferred to a short seller to complete a short sale would appear to lose his status as a partner with respect to those units for federal income tax purposes. Please read “— Tax Consequences of Unit Ownership — Treatment of Short Sales.”

 

Items of our income, gain, loss or deduction would not appear to be reportable by a unitholder who is not a partner for federal income tax purposes, and any cash distributions received by a unitholder who is not a partner for federal income tax purposes would therefore appear to be fully taxable as ordinary income. These holders are urged to consult their own tax advisors with respect to their tax consequences of holding common units in Williams Partners L.P. for federal income tax purposes. The references to “unitholders” in the discussion that follows are to persons who are treated as partners in Williams Partners L.P. for federal income tax purposes.

 

Tax Consequences of Unit Ownership

 

Flow-through of Taxable Income

 

We do not pay any federal income tax. Instead, each unitholder will be required to report on his income tax return his share of our income, gains, losses and deductions without regard to whether corresponding cash distributions are received by him. Consequently, we may allocate income to a unitholder even if he has not received a cash distribution. Each unitholder will be required to include in income his allocable share of our income, gains, losses and deductions for our taxable year or years ending with or within his taxable year. Our taxable year ends on December 31.

Treatment of Distributions

 

Distributions by us to a unitholder generally will not be taxable to the unitholder for federal income tax purposes, except to the extent the amount of any such cash distribution exceeds his tax basis in his common units immediately before the distribution. Our cash distributions in excess of a unitholder’s tax basis in his common units generally will be considered to be gain from the sale or exchange of the common units, taxable in accordance with the rules described under “— Disposition of Common Units” below. Any reduction in a unitholder’s share of our liabilities for which no partner, including our general partner, bears the economic risk of loss, known as “nonrecourse liabilities,” will be treated as a distribution of cash to that unitholder. To the extent our distributions cause a unitholder’s “at risk” amount to be less than zero at the end of any taxable year, he must recapture any losses deducted in previous years. Please read “— Limitations on Deductibility of Losses.”

 

A decrease in a unitholder’s percentage interest in us because of our issuance of additional common units will decrease his share of our nonrecourse liabilities, and thus will result in a corresponding deemed distribution of cash, which may constitute a non-pro rata distribution. A non-pro rata distribution of money or property may result in ordinary income to a unitholder, regardless of his tax basis in his common units, if the distribution reduces the unitholder’s share of our “unrealized receivables,” including depreciation recapture, and/or substantially appreciated “inventory items,” both as defined in Section 751 of the Internal Revenue Code, and collectively, “Section 751 Assets.” To that extent, he will be treated as having been distributed his proportionate share of the Section 751 Assets and having then exchanged those assets with us in return for the non-pro rata portion of the actual distribution made to him. This latter deemed exchange will generally result in the unitholder’s realization of ordinary income, which will equal the excess of the non-pro rata portion of that distribution over the unitholder’s tax basis for the share of Section 751 Assets deemed relinquished in the exchange.

 

Basis of Common Units

 

A unitholder’s initial tax basis for his common units will be the amount he paid for the common units plus his share of our nonrecourse liabilities. That basis will be increased by his share of our income and by any increases in his share of our nonrecourse liabilities. That basis generally will be decreased, but not below zero, by distributions from us, by the unitholder’s share of our losses, by any decreases in his share of our nonrecourse liabilities and by his share of our expenditures that are not deductible in computing taxable income and are not required to be capitalized. A unitholder will have no share of our debt that is recourse to our general partner to the extent of the general partner’s “net value” as defined in regulations under Section 752 of the Internal Revenue Code, but will have a share, generally based on his share of profits, of our nonrecourse liabilities. Please read “— Disposition of Common Units — Recognition of Gain or Loss.”

 

Limitations on Deductibility of Losses

 

The deduction by a unitholder of his share of our losses will be limited to the tax basis in his units and, in the case of an individual unitholder or a corporate unitholder, if more than 50% of the value of the corporate unitholder’s stock is owned directly or indirectly by or for five or fewer individuals or some tax-exempt organizations, to the amount for which the unitholder is considered to be “at risk” with respect to our activities, if that amount is less than his tax basis. A unitholder subject to these limitations must recapture losses deducted in previous years to the extent that distributions cause his at risk amount to be less than zero at the end of any taxable year. Losses disallowed to a unitholder or recaptured as a result of these limitations will carry forward and will be allowable as a deduction in a later year to the extent that his tax basis or at risk amount, whichever is the limiting factor, is subsequently increased, provided such losses are otherwise allowable. Upon the taxable disposition of a unit, any gain recognized by a unitholder can be offset by losses that were previously suspended by the at risk limitation but may not be offset by losses suspended by the basis limitation. Any excess loss above that gain previously suspended by the at risk or basis limitations is no longer utilizable.

 

In general, a unitholder will be at risk to the extent of the tax basis of his units, excluding any portion of that basis attributable to his share of our nonrecourse liabilities, reduced by (i) any portion of that basis representing amounts otherwise protected against loss because of a guarantee, stop loss agreement or other similar arrangement and (ii) any amount of money he borrows to acquire or hold his units, if the lender of those borrowed funds owns an

interest in us, is related to another unitholder who has an interest in us or can look only to the units for repayment. A unitholder’s at risk amount will increase or decrease as the tax basis of the unitholder’s units increases or decreases, other than tax basis increases or decreases attributable to increases or decreases in his share of our nonrecourse liabilities.

 

The passive loss limitations generally provide that individuals, estates, trusts and some closely-held corporations and personal service corporations are permitted to deduct losses from passive activities, which are generally trade or business activities in which the taxpayer does not materially participate, only to the extent of the taxpayer’s income from those passive activities. The passive loss limitations are applied separately with respect to each publicly traded partnership. Consequently, any passive losses we generate will only be available to offset our passive income generated in the future and will not be available to offset income from other passive activities or investments, including our investments or investments in other publicly traded partnerships, or a unitholder’s salary or active business income. Passive losses that are not deductible because they exceed a unitholder’s share of income we generate may be deducted in full when the unitholder disposes of his entire investment in us in a fully taxable transaction with an unrelated party. The passive loss limitations are applied after other applicable limitations on deductions, including the at risk rules and the basis limitation.

 

A unitholder’s share of our net income may be offset by any of our suspended passive losses, but it may not be offset by any other current or carryover losses from other passive activities, including those attributable to other publicly traded partnerships.

 

Limitations on Interest Deductions

 

The deductibility of a non-corporate taxpayer’s “investment interest expense” is generally limited to the amount of that taxpayer’s “net investment income.” Investment interest expense includes:

 

 

The computation of a unitholder’s investment interest expense will take into account interest on any margin account borrowing or other loan incurred to purchase or carry a unit. Net investment income includes gross income from property held for investment and amounts treated as portfolio income under the passive loss rules, less deductible expenses, other than interest, directly connected with the production of investment income, but generally does not include gains attributable to the disposition of property held for investment. The IRS has indicated that net passive income earned by a publicly traded partnership will be treated as investment income to its unitholders. In addition, the unitholder’s share of our portfolio income will be treated as investment income.

 

Entity-Level Collections

 

If we are required or elect under applicable law to pay any federal, state, local or foreign income tax on behalf of any unitholder or our general partner or any former unitholder, we are authorized to pay those taxes from our funds. That payment, if made, will be treated as a distribution of cash to the unitholder on whose behalf the payment was made. If the payment is made on behalf of a person whose identity cannot be determined, we are authorized to treat the payment as a distribution to all current unitholders. We are authorized to amend our partnership agreement in the manner necessary to maintain uniformity of intrinsic tax characteristics of units and to adjust later distributions, so that after giving effect to these distributions, the priority and characterization of distributions otherwise applicable under our partnership agreement is maintained as nearly as is practicable. Payments by us as described above could give rise to an overpayment of tax on behalf of an individual unitholder in which event the unitholder would be required to file a claim in order to obtain a credit or refund.

Allocation of Income, Gain, Loss and Deduction

 

In general, if we have a net profit, our items of income, gain, loss and deduction will be allocated among our general partner and the unitholders in accordance with their percentage interests in us. At any time that distributions are made to the common units in excess of distributions to the subordinated units, or incentive distributions are made to our general partner, gross income will be allocated to the recipients to the extent of these distributions. If we have a net loss for the entire year, that loss will be allocated first to our general partner and the unitholders in accordance with their percentage interests in us to the extent of their positive capital accounts and, second, to our general partner.

 

Specified items of our income, gain, loss and deduction will be allocated under Section 704(c) of the Internal Revenue Code to account for the difference between the tax basis and fair market value of our assets at the time we issue units in an offering, referred to in this discussion as “Contributed Property.” The effect of these allocations to a unitholder purchasing common units in such offering will be essentially the same as if the tax basis of Contributed Property was equal to its fair market value at the time of such offering. In the event we issue additional common units or engage in certain other transactions in the future, “reverse Section 704(c) allocations,” similar to the Section 704(c) allocations described above, will be made to all holders of partnership interests, including purchasers of common units in such offering, to account for the difference, at the time of the future transaction, between the “book” basis for purposes of maintaining capital accounts and the fair market value of all property held by us at the time of the future transaction. In addition, items of recapture income will be allocated to the extent possible to the unitholder who was allocated the deduction giving rise to the treatment of that gain as recapture income in order to minimize the recognition of ordinary income by some unitholders. Finally, although we do not expect that our operations will result in the creation of negative capital accounts, if negative capital accounts nevertheless result, items of our income and gain will be allocated in such amount and manner as is needed to eliminate the negative balance as quickly as possible.

 

An allocation of items of our income, gain, loss or deduction, other than an allocation required by the Internal Revenue Code to eliminate the difference between a partner’s “book” capital account, credited with the fair market value of Contributed Property, and “tax” capital account, credited with the tax basis of Contributed Property, referred to in this discussion as the “Book-Tax Disparity,” will generally be given effect for federal income tax purposes in determining a partner’s share of an item of income, gain, loss or deduction only if the allocation has substantial economic effect. In any other case, a partner’s share of an item will be determined on the basis of his interest in us, which will be determined by taking into account all the facts and circumstances, including:

 

 

Andrews Kurth LLP is of the opinion that, with the exception of the issues described in “— Tax Consequences of Unit Ownership — Section 754 Election,” “— Uniformity of Units” and “— Disposition of Common Units — Allocations Between Transferors and Transferees,” allocations under our partnership agreement will be given effect for federal income tax purposes in determining a partner’s share of an item of income, gain, loss or deduction.

 

Treatment of Short Sales

 

A unitholder whose units are loaned to a “short seller” to cover a short sale of units may be considered as having disposed of those units. If so, such unitholder would no longer be treated for tax purposes as a partner with respect to those units during the period of the loan and may recognize gain or loss from the disposition. As a result, during this period:

 

 

Andrews Kurth LLP has not rendered an opinion regarding the treatment of a unitholder where common units are loaned to a short seller to cover a short sale of common units; therefore, unitholders desiring to assure their status as partners and avoid the risk of gain recognition from a loan to a short seller are urged to modify any applicable brokerage account agreements to prohibit their brokers from loaning their units. The IRS has announced that it is studying issues relating to the tax treatment of short sales of partnership interests. Please also read “— Disposition of Common Units — Recognition of Gain or Loss.”

 

Alternative Minimum Tax

 

Each unitholder will be required to take into account his distributive share of any items of our income, gain, loss or deduction for purposes of the alternative minimum tax. The current minimum tax rate for non-corporate taxpayers is 26% on the first $175,000 of alternative minimum taxable income in excess of the exemption amount and 28% on any additional alternative minimum taxable income. Prospective unitholders are urged to consult with their tax advisors as to the impact of an investment in units on their liability for the alternative minimum tax.

 

Tax Rates

 

In general, the highest effective United States federal income tax rate for individuals is currently 35% and the maximum United States federal income tax rate for net capital gains of an individual is currently 15% if the asset disposed of was a capital asset held for more than 12 months at the time of disposition. However, absent new legislation extending the current rates, beginning January 1, 2011, the highest marginal United States federal income tax rate applicable to ordinary income and long-term capital gains of individuals will increase to 39.6% and 20%, respectively.

 

Section 754 Election

 

We have made the election permitted by Section 754 of the Internal Revenue Code. That election is irrevocable without the consent of the IRS. The election will generally permit us to adjust a common unit purchaser’s tax basis in our assets (“inside basis”) under Section 743(b) of the Internal Revenue Code to reflect his purchase price. This election does not apply to a person who purchases common units directly from us. The Section 743(b) adjustment belongs to the purchaser and not to other unitholders. For purposes of this discussion, a unitholder’s inside basis in our assets will be considered to have two components: (1) his share of our tax basis in our assets (“common basis”) and (2) his Section 743(b) adjustment to that basis.

 

Where the remedial allocation method is adopted (which we have adopted), Treasury Regulations under Section 743 of the Internal Revenue Code require a portion of the Section 743(b) adjustment attributable to recovery property under Section 168 of the Internal Revenue Code to be depreciated over the remaining cost recovery period for the property’s unamortized Book-Tax Disparity. Under Treasury Regulation Section 1.167(c)-1(a)(6), a Section 743(b) adjustment attributable to property subject to depreciation under Section 167 of the Internal Revenue Code, rather than cost recovery deductions under Section 168, is generally required to be depreciated using either the straight-line method or the 150% declining balance method. Under our partnership agreement, our general partner is authorized to take a position to preserve the uniformity of units even if that position is not consistent with these Treasury Regulations. Please read “— Uniformity of Units.”

 

Although Andrews Kurth LLP is unable to opine as to the validity of this approach because there is no controlling authority on this issue, we intend to depreciate the portion of a Section 743(b) adjustment attributable to unrealized appreciation in the value of Contributed Property, to the extent of any unamortized Book-Tax Disparity, using a rate of depreciation or amortization derived from the depreciation or amortization method and useful life applied to the unamortized Book-Tax Disparity of the property, or treat that portion as non-amortizable to the extent attributable to property the common basis of which is not amortizable. This method is consistent with the Treasury Regulations under Section 743 of the Internal Revenue Code but is arguably inconsistent with Treasury Regulation Section 1.167(c)-1(a)(6), which is not expected to directly apply to a material portion of our assets. To the extent this Section 743(b) adjustment is attributable to appreciation in value in excess of the unamortized Book-Tax Disparity, we will apply the rules described in the Treasury Regulations and legislative history. If we determine that this position cannot reasonably be taken, we may take a depreciation or amortization position under which all

purchasers acquiring units in the same month would receive depreciation or amortization, whether attributable to common basis or a Section 743(b) adjustment, based upon the same applicable rate as if they had purchased a direct interest in our assets. This kind of aggregate approach may result in lower annual depreciation or amortization deductions than would otherwise be allowable to some unitholders. Please read “— Uniformity of Units.”

 

A Section 754 election is advantageous if the transferee’s tax basis in his units is higher than the units’ share of the aggregate tax basis of our assets immediately prior to the transfer. In that case, as a result of the election, the transferee would have, among other items, a greater amount of depreciation deductions and his share of any gain or loss on a sale of our assets would be less. Conversely, a Section 754 election is disadvantageous if the transferee’s tax basis in his units is lower than those units’ share of the aggregate tax basis of our assets immediately prior to the transfer. Thus, the fair market value of the units may be affected either favorably or unfavorably by the election. A basis adjustment is required regardless of whether a Section 754 election is made in the case of a transfer of an interest in us if we have a substantial built-in loss immediately after the transfer, or if we distribute property and have a substantial basis reduction. Generally a basis reduction or a built-in loss is substantial if it exceeds $250,000.

 

The calculations involved in the Section 754 election are complex and will be made on the basis of assumptions as to the value of our assets and other matters. For example, the allocation of the Section 743(b) adjustment among our assets must be made in accordance with the Internal Revenue Code. The IRS could seek to reallocate some or all of any Section 743(b) adjustment we allocated to our tangible assets to goodwill instead. Goodwill, an intangible asset, is generally either nonamortizable or amortizable over a longer period of time or under a less accelerated method than our tangible assets. We cannot assure you that the determinations we make will not be successfully challenged by the IRS and that the deductions resulting from them will not be reduced or disallowed altogether. Should the IRS require a different basis adjustment to be made, and should, in our opinion, the expense of compliance exceed the benefit of the election, we may seek permission from the IRS to revoke our Section 754 election. If permission is granted, a subsequent purchaser of units may be allocated more income than he would have been allocated had the election not been revoked.

 

Tax Treatment of Operations

 

Accounting Method and Taxable Year

 

We use the year ending December 31 as our taxable year and the accrual method of accounting for federal income tax purposes. Each unitholder will be required to include in income his share of our income, gain, loss and deduction for our taxable year or years ending within or with his taxable year. In addition, a unitholder who has a taxable year different than our taxable year and who disposes of all of his units following the close of our taxable year but before the close of his taxable year must include his share of our income, gain, loss and deduction in income for his taxable year, with the result that he will be required to include in income for his taxable year his share of more than one year of our income, gain, loss and deduction. Please read “— Disposition of Common Units — Allocations Between Transferors and Transferees.”

 

Initial Tax Basis, Depreciation and Amortization

 

The tax basis of our assets is used for purposes of computing depreciation and cost recovery deductions and, ultimately, gain or loss on the disposition of these assets. The federal income tax burden associated with the difference between the fair market value of our assets and their tax basis immediately prior to the time we issue units in an offering will be borne by our general partner, its affiliates and our unitholders as of that time. Please read “— Tax Consequences of Unit Ownership — Allocation of Income, Gain, Loss and Deduction.”

 

To the extent allowable, we may elect to use the depreciation and cost recovery methods that will result in the largest deductions being taken in the early years after assets are placed in service. Property we subsequently acquire or construct may be depreciated using accelerated methods permitted by the Internal Revenue Code.

 

If we dispose of depreciable property by sale, foreclosure or otherwise, all or a portion of any gain, determined by reference to the amount of depreciation previously deducted and the nature of the property, may be subject to the recapture rules and taxed as ordinary income rather than capital gain. Similarly, a unitholder who has taken cost recovery or depreciation deductions with respect to property we own will likely be required to recapture some or all

of those deductions as ordinary income upon a sale of his interest in us. Please read “— Tax Consequences of Unit Ownership — Allocation of Income, Gain, Loss and Deduction” and “— Disposition of Common Units — Recognition of Gain or Loss.”

 

The costs incurred in selling our units (called “syndication expenses”) must be capitalized and cannot be deducted currently, ratably or upon our termination. There are uncertainties regarding the classification of costs as organization expenses, which we may be able to amortize, and as syndication expenses, which we may not amortize. The underwriting discounts and commissions we incur will be treated as syndication expenses.

 

Valuation and Tax Basis of Our Properties

 

The federal income tax consequences of the ownership and disposition of units will depend in part on our estimates of the relative fair market values, and the tax bases, of our assets. Although we may from time to time consult with professional appraisers regarding valuation matters, we will make many of the relative fair market value estimates ourselves. These estimates and determinations of basis are subject to challenge and will not be binding on the IRS or the courts. If the estimates of fair market value or basis are later found to be incorrect, the character and amount of items of income, gain, loss or deductions previously reported by unitholders might change, and unitholders might be required to adjust their tax liability for prior years and incur interest and penalties with respect to those adjustments.

 

Disposition of Common Units

 

Recognition of Gain or Loss

 

Gain or loss will be recognized on a sale of units equal to the difference between the unitholder’s amount realized and the unitholder’s tax basis for the units sold. A unitholder’s amount realized will be measured by the sum of the cash or the fair market value of other property received by him plus his share of our nonrecourse liabilities attributable to the common units sold. Because the amount realized includes a unitholder’s share of our nonrecourse liabilities, the gain recognized on the sale of units could result in a tax liability in excess of any cash received from the sale.

 

Prior distributions from us in excess of cumulative net taxable income for a common unit that decreased a unitholder’s tax basis in that common unit will, in effect, become taxable income if the common unit is sold at a price greater than the unitholder’s tax basis in that common unit, even if the price received is less than his original cost.

 

Except as noted below, gain or loss recognized by a unitholder, other than a “dealer” in units, on the sale or exchange of a unit held for more than one year will generally be taxable as capital gain or loss. Capital gain recognized by an individual on the sale of units held more than 12 months will generally be taxed at a maximum rate of 15% through December 31, 2010 and 20% thereafter (absent legislation extending the current rates). However, a portion of this gain or loss, which will likely be substantial, will be separately computed and taxed as ordinary income or loss under Section 751 of the Internal Revenue Code to the extent attributable to assets giving rise to depreciation recapture or other “unrealized receivables” or to “inventory items” we own. The term “unrealized receivables” includes potential recapture items, including depreciation recapture. Ordinary income attributable to unrealized receivables, inventory items and depreciation recapture may exceed net taxable gain realized on the sale of a unit and may be recognized even if there is a net taxable loss realized on the sale of a unit. Thus, a unitholder may recognize both ordinary income and a capital loss upon a sale of units. Net capital losses may offset capital gains and no more than $3,000 of ordinary income each year, in the case of individuals, and may only be used to offset capital gains in the case of corporations.

 

The IRS has ruled that a partner who acquires interests in a partnership in separate transactions must combine those interests and maintain a single adjusted tax basis for all those interests. Upon a sale or other disposition of less than all of those interests, a portion of that tax basis must be allocated to the interests sold using an “equitable apportionment” method, which generally means that the tax basis allocated to the interest sold equals an amount that bears the same relation to the partner’s tax basis in his entire interest in the partnership as the value of the interest sold bears to the value of the partner’s entire interest in the partnership. Treasury Regulations under

Section 1223 of the Internal Revenue Code allow a selling unitholder who can identify common units transferred with an ascertainable holding period to elect to use the actual holding period of the common units transferred. Thus, according to the ruling, a common unitholder will be unable to select high or low basis common units to sell as would be the case with corporate stock, but, according to the Treasury Regulations, may designate specific common units sold for purposes of determining the holding period of units transferred. A unitholder electing to use the actual holding period of common units transferred must consistently use that identification method for all subsequent sales or exchanges of common units. A unitholder considering the purchase of additional units or a sale of common units purchased in separate transactions is urged to consult his tax advisor as to the possible consequences of this ruling and application of the Treasury Regulations.

 

Specific provisions of the Internal Revenue Code affect the taxation of some financial products and securities, including partnership interests, by treating a taxpayer as having sold an “appreciated” partnership interest, one in which gain would be recognized if it were sold, assigned or terminated at its fair market value, if the taxpayer or related persons enter(s) into:

 

 

Moreover, if a taxpayer has previously entered into a short sale, an offsetting notional principal contract or a futures or forward contract with respect to the partnership interest, the taxpayer will be treated as having sold that position if the taxpayer or a related person then acquires the partnership interest or substantially identical property. The Secretary of the Treasury is also authorized to issue regulations that treat a taxpayer that enters into transactions or positions that have substantially the same effect as the preceding transactions as having constructively sold the financial position.

 

Allocations Between Transferors and Transferees

 

In general, our taxable income or loss will be determined annually, will be prorated on a monthly basis and will be subsequently apportioned among the unitholders in proportion to the number of units owned by each of them as of the opening of the applicable exchange on the first business day of the month, which we refer to in this discussion as the “Allocation Date.” However, gain or loss realized on a sale or other disposition of our assets other than in the ordinary course of business will be allocated among the unitholders on the Allocation Date in the month in which that gain or loss is recognized. As a result, a unitholder transferring units may be allocated income, gain, loss and deduction realized after the date of transfer.

 

The use of this method may not be permitted under existing Treasury Regulations. Accordingly, Andrews Kurth LLP is unable to opine on the validity of this method of allocating income and deductions between unitholders. We use this method because it is not administratively feasible to make these allocations on a more frequent basis. If this method is not allowed under the Treasury Regulations, or only applies to transfers of less than all of the unitholder’s interest, our taxable income or losses might be reallocated among the unitholders. We are authorized to revise our method of allocation between unitholders, as well as among unitholders whose interests vary during a taxable year, to conform to a method permitted under future Treasury Regulations.

 

A unitholder who owns units at any time during a quarter and who disposes of them prior to the record date set for a cash distribution for that quarter will be allocated items of our income, gain, loss and deductions attributable to that quarter but will not be entitled to receive that cash distribution.

 

Notification Requirements

 

A unitholder who sells any of his units, other than through a broker, generally is required to notify us in writing of that sale within 30 days after the sale (or, if earlier, January 15 of the year following the sale). A purchaser of units who purchases units from another unitholder is generally required to notify us in writing of that purchase within 30 days after the purchase. We are required to notify the IRS of that transaction and to furnish specified information to the transferor and transferee. Failure to notify us of a transfer of units may, in some cases, lead to the imposition of

penalties. However, these reporting requirements do not apply to a sale by an individual who is a citizen of the United States and who effects the sale or exchange through a broker who will satisfy such requirements.

 

Constructive Termination

 

We will be considered to have been terminated for tax purposes if there are sales or exchanges which, in the aggregate, constitute 50% or more of the total interests in our capital and profits within a 12-month period. A constructive termination results in the closing of our taxable year for all unitholders. In the case of a unitholder reporting on a taxable year different from our taxable year, the closing of our taxable year may result in more than 12 months of our taxable income or loss being includable in his taxable income for the year of termination. A constructive termination occurring on a date other than December 31 will result in us filing two tax returns for one fiscal year and the cost of preparation of these returns will be borne by all unitholders. We would be required to make new tax elections after a termination, including a new election under Section 754 of the Internal Revenue Code, and a termination would result in a deferral of our deductions for depreciation. A termination could also result in penalties if we were unable to determine that the termination had occurred. Moreover, a termination might either accelerate the application of, or subject us to, any tax legislation enacted before the termination.

 

Uniformity of Units

 

Because we cannot match transferors and transferees of units, we must maintain uniformity of the economic and tax characteristics of the units to a purchaser of these units. In the absence of uniformity, we may be unable to completely comply with a number of federal income tax requirements, both statutory and regulatory. A lack of uniformity can result from a literal application of Treasury Regulation Section 1.167(c)-1(a)(6). Any non-uniformity could have a negative impact on the value of the units. Please read “— Tax Consequences of Unit Ownership — Section 754 Election.”

 

We intend to depreciate the portion of a Section 743(b) adjustment attributable to unrealized appreciation in the value of Contributed Property, to the extent of any unamortized Book-Tax Disparity, using a rate of depreciation or amortization derived from the depreciation or amortization method and useful life applied to the unamortized Book-Tax Disparity of that property, or treat that portion as nonamortizable, to the extent attributable to property which is not amortizable, consistent with the Treasury Regulations under Section 743 of the Internal Revenue Code, even though that position may be inconsistent with Treasury Regulation Section 1.167(c)-1(a)(6), which is not expected to directly apply to a material portion of our assets. Please read “— Tax Consequences of Unit Ownership — Section 754 Election.” To the extent that the Section 743(b) adjustment is attributable to appreciation in value in excess of the unamortized Book-Tax Disparity, we will apply the rules described in the Treasury Regulations and legislative history. If we determine that this position cannot reasonably be taken, we may adopt a depreciation and amortization position under which all purchasers acquiring units in the same month would receive depreciation and amortization deductions, whether attributable to a common basis or Section 743(b) adjustment, based upon the same applicable rate as if they had purchased a direct interest in our property. If this position is adopted, it may result in lower annual depreciation and amortization deductions than would otherwise be allowable to some unitholders and risk the loss of depreciation and amortization deductions not taken in the year that these deductions are otherwise allowable. This position will not be adopted if we determine that the loss of depreciation and amortization deductions will have a material adverse effect on the unitholders. If we choose not to utilize this aggregate method, we may use any other reasonable depreciation and amortization method to preserve the uniformity of the intrinsic tax characteristics of any units that would not have a material adverse effect on the unitholders. Our counsel, Andrews Kurth LLP, is unable to opine on the validity of any of these positions. The IRS may challenge any method of depreciating the Section 743(b) adjustment described in this paragraph. If this challenge were sustained, the uniformity of units might be affected, and the gain from the sale of units might be increased without the benefit of additional deductions. Please read “— Disposition of Common Units — Recognition of Gain or Loss.”

Tax-Exempt Organizations and Other Investors

 

Ownership of units by employee benefit plans, other tax-exempt organizations, non-resident aliens, foreign corporations and other foreign persons raises issues unique to those investors and, as described below, may have substantially adverse tax consequences to them.

 

Employee benefit plans and most other organizations exempt from federal income tax, including individual retirement accounts and other retirement plans, are subject to federal income tax on unrelated business taxable income. Virtually all of our income allocated to a unitholder that is a tax-exempt organization will be unrelated business taxable income and will be taxable to them.

 

Non-resident aliens and foreign corporations, trusts or estates that own units will be considered to be engaged in business in the United States because of the ownership of units. As a consequence, they will be required to file federal tax returns to report their share of our income, gain, loss or deduction and pay federal income tax at regular rates on their share of our net income or gain. Moreover, under rules applicable to publicly traded partnerships, we will withhold tax at the highest applicable effective tax rate from cash distributions made quarterly to foreign unitholders. Each foreign unitholder must obtain a taxpayer identification number from the IRS and submit that number to our transfer agent on a Form W-8BEN or applicable substitute form in order to obtain credit for these withholding taxes. A change in applicable law may require us to change these procedures.

 

In addition, because a foreign corporation that owns units will be treated as engaged in a United States trade or business, that corporation may be subject to the United States branch profits tax at a rate of 30%, in addition to regular federal income tax, on its share of our income and gain, as adjusted for changes in the foreign corporation’s “U.S. net equity,” that is effectively connected with the conduct of a United States trade or business. That tax may be reduced or eliminated by an income tax treaty between the United States and the country in which the foreign corporate unitholder is a “qualified resident.” In addition, this type of unitholder is subject to special information reporting requirements under Section 6038C of the Internal Revenue Code.

 

Under a ruling of the IRS, a foreign unitholder who sells or otherwise disposes of a unit will be subject to federal income tax on gain realized on the sale or disposition of that unit to the extent that this gain is effectively connected with a United States trade or business of the foreign unitholder. Because a foreign unitholder is considered to be engaged in a trade or business in the United States by virtue of the ownership of the common units, under this ruling, a foreign unitholder who sells or otherwise disposes of a common unit generally will be subject to federal income tax on gain realized on the sale or other disposition of the common units. Apart from the ruling, a foreign unitholder will not be taxed or subject to withholding upon the sale or disposition of a unit if he has owned less than 5% in value of the units during the five-year period ending on the date of the disposition and if the units are regularly traded on an established securities market at the time of the sale or disposition.

 

Administrative Matters

 

Information Returns and Audit Procedures

 

We intend to furnish to each unitholder, within 90 days after the close of each taxable year, specific tax information, including a Schedule K-1, which describes each unitholder’s share of our income, gain, loss and deduction for our preceding taxable year. In preparing this information, which will not be reviewed by counsel, we will take various accounting and reporting positions, some of which have been mentioned earlier, to determine each unitholder’s share of income, gain, loss and deduction. We cannot assure you that those positions will in all cases yield a result that conforms to the requirements of the Internal Revenue Code, Treasury Regulations or administrative interpretations of the IRS. Neither we nor Andrews Kurth LLP can assure prospective unitholders that the IRS will not successfully contend in court that those positions are impermissible. Any challenge by the IRS could negatively affect the value of the units.

 

The IRS may audit our federal income tax information returns. Adjustments resulting from an IRS audit may require each unitholder to adjust a prior year’s tax liability, and possibly may result in an audit of his return.

 

Any audit of a unitholder’s return could result in adjustments not related to our returns as well as those related to our returns.

Partnerships generally are treated as separate entities for purposes of federal tax audits, judicial review of administrative adjustments by the IRS and tax settlement proceedings. The tax treatment of partnership items of income, gain, loss and deduction are determined in a partnership proceeding rather than in separate proceedings with the partners. The Internal Revenue Code requires that one partner be designated as the “Tax Matters Partner” for these purposes. The partnership agreement names our general partner as our Tax Matters Partner.

 

The Tax Matters Partner will make some elections on our behalf and on behalf of unitholders. In addition, the Tax Matters Partner can extend the statute of limitations for assessment of tax deficiencies against unitholders for items in our returns. The Tax Matters Partner may bind a unitholder with less than a 1% profits interest in us to a settlement with the IRS unless that unitholder elects, by filing a statement with the IRS, not to give that authority to the Tax Matters Partner. The Tax Matters Partner may seek judicial review, by which all the unitholders are bound, of a final partnership administrative adjustment and, if the Tax Matters Partner fails to seek judicial review, judicial review may be sought by any unitholder having at least a 1% interest in profits or by any group of unitholders having in the aggregate at least a 5% interest in profits. However, only one action for judicial review will go forward, and each unitholder with an interest in the outcome may participate in that action.

 

A unitholder must file a statement with the IRS identifying the treatment of any item on his federal income tax return that is not consistent with the treatment of the item on our return. Intentional or negligent disregard of this consistency requirement may subject a unitholder to substantial penalties.

 

Nominee Reporting

 

Persons who hold an interest in us as a nominee for another person are required to furnish to us:

 

(a) the name, address and taxpayer identification number of the beneficial owner and the nominee,

 

(b) whether the beneficial owner is:

 

(1) a person that is not a United States person

 

(2) a foreign government, an international organization or any wholly owned agency or instrumentality of either of the foregoing; or

 

(3) a tax-exempt entity;

 

(c) the amount and description of units held, acquired or transferred for the beneficial owner; and

 

(d) specific information including the dates of acquisitions and transfers, means of acquisitions and transfers, and acquisition cost for purchases, as well as the amount of net proceeds from sales.

 

Brokers and financial institutions are required to furnish additional information, including whether they are United States persons and specific information on units they acquire, hold or transfer for their own account. A penalty of $50 per failure, up to a maximum of $100,000 per calendar year, is imposed by the Internal Revenue Code for failure to report that information to us. The nominee is required to supply the beneficial owner of the units with the information furnished to us.

 

Accuracy-Related Penalties

 

An additional tax equal to 20% of the amount of any portion of an underpayment of tax that is attributable to one or more specified causes, including negligence or disregard of rules or regulations, substantial understatements of income tax and substantial valuation misstatements, is imposed by the Internal Revenue Code. No penalty will be imposed, however, for any portion of an underpayment if it is shown that there was a reasonable cause for that portion and that the taxpayer acted in good faith regarding that portion.

 

For individuals, a substantial understatement of income tax in any taxable year exists if the amount of the understatement exceeds the greater of 10% of the tax required to be shown on the return for the taxable year or $5,000. The amount of any understatement subject to penalty generally is reduced if any portion is attributable to a position adopted on the return:

 

(a) for which there is, or was, “substantial authority;” or

 

(b) as to which there is a reasonable basis if the pertinent facts of that position are adequately disclosed on the return.

If any item of income, gain, loss or deduction included in the distributive shares of unitholders might result in that kind of an “understatement” of income for which no “substantial authority” exists, we must disclose the pertinent facts on our return. In addition, we will make a reasonable effort to furnish sufficient information for unitholders to make adequate disclosure on their returns and to take other actions as may be appropriate to permit unitholders to avoid liability for this penalty. More stringent rules apply to “tax shelters” which we do not believe includes us.

 

A substantial valuation misstatement exists if (a) the value of any property, or the tax basis of any property, claimed on a tax return is 150% or more of the amount determined to be the correct amount of the valuation or tax basis, (b) the price for any property or services (or for the use of property) claimed on any such return with respect to any transaction between persons described in Internal Revenue Code Section 482 is 200% or more (or 50% or less) of the amount determined under Section 482 to be the correct amount of such price, or (c) the net Internal Revenue Code Section 482 transfer price adjustment for the taxable year exceeds the lesser of $5 million or 10% of the taxpayer’s gross receipts. No penalty is imposed unless the portion of the underpayment attributable to a substantial valuation misstatement exceeds $5,000 ($10,000 for most corporations). The penalty is increased to 40% in the event of a gross valuation misstatement. We do not anticipate making any valuation misstatements.

 

Reportable Transactions

 

If we were to engage in a “reportable transaction,” we (and possibly you and others) would be required to make a detailed disclosure of the transaction to the IRS. A transaction may be a reportable transaction based upon any of several factors, including the fact that it is a type of tax avoidance transaction publicly identified by the IRS as a “listed transaction” or a “transaction of interest” or that it produces certain kinds of losses in excess of $2 million in any single year, or $4 million in any combination of six successive tax years. Our participation in a reportable transaction could increase the likelihood that our federal income tax information return (and possibly your tax return) would be audited by the IRS. Please read “— Information Returns and Audit Procedures” above.

 

Moreover, if we were to participate in a reportable transaction with a significant purpose to avoid or evade tax, or in any listed transaction, you may be subject to the following provisions of the American Jobs Creation Act of 2004:

 

 

We do not expect to engage in any “reportable transactions.”

 

State, Local, Foreign and Other Tax Considerations

 

In addition to federal income taxes, you likely will be subject to other taxes, such as state, local and foreign income taxes, unincorporated business taxes, and estate, inheritance or intangible taxes that may be imposed by the various jurisdictions in which we do business or own property or in which you are a resident. Although an analysis of those various taxes is not presented here, each prospective unitholder should consider their potential impact on his investment in us. We currently own property or conduct business in a number of states. Most of these states impose an income tax on individuals, corporations and other entities. We may also own property or do business in other jurisdictions in the future. Although you may not be required to file a return and pay taxes in some jurisdictions because your income from that jurisdiction falls below the filing and payment requirement, you will be required to file income tax returns and to pay income taxes in many of the jurisdictions in which we do business or own property and may be subject to penalties for failure to comply with those requirements. In some jurisdictions, tax losses may not produce a tax benefit in the year incurred and may not be available to offset income in subsequent taxable years. Some jurisdictions may require us, or we may elect, to withhold a percentage of income from amounts to be distributed to a unitholder who is not a resident of the jurisdiction. Withholding, the amount of which may be greater or less than a particular unitholder’s income tax liability to the jurisdiction, generally does not relieve a

nonresident unitholder from the obligation to file an income tax return. Amounts withheld will be treated as if distributed to unitholders for purposes of determining the amounts distributed by us. Please read “— Tax Consequences of Unit Ownership — Entity-Level Collections.” Based on current law and our estimate of our future operations, our general partner anticipates that any amounts required to be withheld will not be material.

 

It is the responsibility of each unitholder to investigate the legal and tax consequences, under the laws of pertinent jurisdictions, of his investment in us. Accordingly, each prospective unitholder is urged to consult, and depend on, his own tax counsel or other advisor with regard to those matters. Further, it is the responsibility of each unitholder to file all state, local and foreign, as well as United States federal tax returns, that may be required of him. Andrews Kurth LLP has not rendered an opinion on the state, local or foreign tax consequences of an investment in us.

 

Tax Consequences of Ownership of Debt Securities

 

A description of the material federal income tax consequences of the acquisition, ownership and disposition of debt securities will be set forth in the prospectus supplement relating to the offering of debt securities.

 

An investment in us by an employee benefit plan is subject to additional considerations because the investments of these plans are usually subject to the fiduciary responsibility and prohibited transaction provisions of ERISA and may also be subject to similar or additional restrictions imposed by the Internal Revenue Code. For these purposes the term “employee benefit plan” includes, but is not limited to, qualified pension, profit-sharing and stock bonus plans, so-called “Keogh” plans, simplified employee pension plans, tax deferred annuities or IRAs, and trusts that fund medical and other benefits for employees. Among other things, consideration should be given to:

 

 

The person with investment discretion with respect to the assets of an employee benefit plan, often called a fiduciary, should determine whether an investment in us is authorized by the appropriate governing instrument and is a proper investment for the plan.

 

Section 406 of ERISA and Section 4975 of the Internal Revenue Code prohibit employee benefit plans and IRAs from engaging in specified transactions involving “plan assets” with parties that are “parties in interest” (under ERISA) or “disqualified persons” (under the Internal Revenue Code) with respect to the plan. These transactions are called “prohibited transactions,” and could result in fiduciary liability and other monetary penalties.

 

In addition to considering whether the purchase of common units is a prohibited transaction, a fiduciary of an employee benefit plan should consider whether the plan will, by investing in us, be deemed to own an undivided interest in our assets, with the result that our operations would be subject to the regulatory restrictions of ERISA. For this purpose, the Department of Labor regulations provide guidance with respect to whether the assets of an entity in which employee benefit plans acquire equity interests would be deemed “plan assets” under some circumstances. Under these regulations, an entity’s assets would not be considered to be “plan assets” if, among other things:

 

(a) the equity interests acquired by employee benefit plans are publicly offered securities — i.e., the equity interests are widely held by 100 or more investors independent of the issuer and each other, freely transferable and registered under some provisions of the federal securities laws;

(b) the entity is an “operating company,” — i.e., it is primarily engaged in the production or sale of a product or service other than the investment of capital either directly or through a majority-owned subsidiary or subsidiaries; or

 

(c) there is no significant investment by benefit plan investors, which is defined to mean that less than 25% of the value of each class of equity interest are held by employee benefit plans (as defined in Section 3(3) of ERISA) subject to Part 4 of Title I of ERISA, any plan to which Section 4975 of the Internal Revenue Code applies, and any entity whose underlying assets include plan assets by reason of a plan’s investment in such entity.

 

Our assets should not be considered “plan assets” under these regulations because it is expected that the investment will satisfy the requirements in (a) above.

 

Plan fiduciaries contemplating a purchase of common units should consult with their own counsel regarding the consequences under ERISA and the Internal Revenue Code in light of the serious penalties imposed on persons who engage in prohibited transactions or other violations

 

We may sell the securities being offered hereby directly to purchasers, through agents, through underwriters or through dealers.

 

We, or agents designated by us, may directly solicit, from time to time, offers to purchase the securities. Any such agent may be deemed to be an underwriter as that term is defined in the Securities Act. We will name the agents involved in the offer or sale of the securities and describe any commissions payable by us to these agents in the prospectus supplement. These agents may act on a best efforts basis for the period of their appointment. The agents may be entitled under agreements they may enter into with us to indemnification by us against specified civil liabilities, including liabilities under the Securities Act. The agents may also be our customers or may engage in transactions with or perform services for us in the ordinary course of business.

 

If we use any underwriters in the sale of the securities in respect of which this prospectus is delivered, we will enter into an underwriting agreement with those underwriters at the time of sale to them. We will set forth the names of the underwriters and the terms of the transaction in a prospectus supplement, which will be used by the underwriters to make resales of the securities in respect of which this prospectus is delivered to the public. We may indemnify the underwriters under the underwriting agreement against specified liabilities, including liabilities under the Securities Act. The underwriters may also be our customers or may engage in transactions with or perform services for us in the ordinary course of business.

 

If we use a dealer in the sale of the securities in respect of which this prospectus is delivered, we will sell those securities to the dealer, as principal. The dealer may then resell those securities to the public at varying prices to be determined by the dealer at the time of resale. We may indemnify the dealers against specified liabilities, including liabilities under the Securities Act. The dealers may also be our customers or may engage in transactions with or perform services for us in the ordinary course of business.

 

We may also sell common units and debt securities directly. In this case, no underwriters or agents would be involved. We may use electronic media, including the Internet, to sell offered securities directly.

 

We will fix the price or prices of our securities at:

 

 

The aggregate maximum compensation the underwriters will receive in connection with the sale of any securities under this prospectus and the registration statement of which it forms a part will not exceed 10% of the gross proceeds from the sale.

Because the Financial Industry Regulatory Authority (FINRA) views our common units as interests in a direct participation program, any offering of common units under the registration statement of which this prospectus forms a part will be made in compliance with FINRA Conduct Rule 2310.

 

To the extent required, this prospectus may be amended or supplemented from time to time to describe a particular plan of distribution. The place and time of delivery for the securities in respect of which this prospectus is delivered will be set forth in the accompanying prospectus supplement.

 

In connection with offerings of securities under the registration statement, of which this prospectus forms a part, and in compliance with applicable law, underwriters, brokers or dealers may engage in transactions that stabilize or maintain the market price of the securities at levels above those that might otherwise prevail in the open market. Specifically, underwriters, brokers or dealers may over-allot in connection with offerings, creating a short position in the securities for their own accounts. For the purpose of covering a syndicate short position or stabilizing the price of the securities, the underwriters, brokers or dealers may place bids for the securities or effect purchases of the securities in the open market. Finally, the underwriters may impose a penalty whereby selling concessions allowed to syndicate members or other brokers or dealers for distribution of the securities in offerings may be reclaimed by the syndicate if the syndicate repurchases previously distributed securities in transactions to cover short positions, in stabilization transactions or otherwise. These activities may stabilize, maintain or otherwise affect the market price of the securities, which may be higher than the price that might otherwise prevail in the open market, and, if commenced, may be discontinued at any time.

 

Unless otherwise specified in the prospectus supplement accompanying this prospectus Andrews Kurth LLP will provide opinions regarding the authorization and validity of the securities for us, and for any underwriter or agent by counsel as named in the applicable prospectus supplement.
