1. Description of Business, Basis of Presentation, and Operating Segment


(a)	Description of Business

Endologix, Inc. (the "Company") is a Delaware corporation with corporate headquarters and production facilities located in Irvine, California. The Company develops, manufactures, markets, and sells innovative medical devices for the treatment of aortic disorders. The Company's principal product (which includes its IntuiTrak, AFX, Nellix, and Ventana brands) is a stent graft and catheter delivery system (the "ELG System"), for the treatment of abdominal aortic aneurysms ("AAA") through minimally-invasive endovascular repair ("EVAR"). Sales of the Company's ELG System (including device extensions and accessories) to hospitals and third-party distributors, provide the sole source of reported revenue.

The Company's ELG System consists of (i) a self-expanding stent covered by graft material (the "ELG Device") and (ii) an accompanying catheter delivery system in which the ELG Device is loaded. Once the ELG Device is fixed in its proper position within the abdominal aorta, it provides a conduit for blood flow and relieves pressure within the weakened or “aneurysmal” section of the vessel wall, greatly reducing the potential for the AAA to rupture.

(b) Basis of Presentation

The accompanying Condensed Consolidated Financial Statements in this Quarterly Report on Form 10-Q have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") and the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). These financial statements include the financial position, results of operations, and cash flows of the Company, including its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated in consolidation.

Certain prior period operating expense amounts for the three months ended March 31, 2013 have been reclassified between "marketing and sales" and "general and administrative" to conform to current period financial statement presentation.

The interim financial data as of June 30, 2013 is unaudited and is not necessarily indicative of the results for a full year. In the opinion of the Company's management, the interim data includes normal and recurring adjustments necessary for a fair presentation of the Company's financial results for the three and six months ended June 30, 2013. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to SEC rules and regulations relating to interim financial statements.

The accompanying Condensed Consolidated Financial Statements should be read in conjunction with the Company's audited Consolidated Financial Statements and Notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2012, filed with the SEC on March 14, 2013.

The Company has one reportable operating segment that is focused exclusively on the development, manufacture, marketing, and sale of ELG Systems for the treatment of aortic disorders. For the three and six months ended June 30, 2013, all of the Company's revenue and related expenses were solely attributable to these activities. Substantially all of the Company's long-lived assets are located in the U.S.

2. Use of Estimates and Summary of Significant Accounting Policies

The preparation of financial statements in conformity with GAAP requires the Company's management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosure of contingent liabilities. On an on-going basis, the Company's management evaluates its estimates, including those related to (i) collectibility of customer accounts; (ii) whether the cost of inventories can be recovered; (iii) the value of goodwill and intangible assets; (iv) realization of tax assets and estimates of tax liabilities; (v) likelihood of payment and value of contingent liabilities; and (vi) potential outcome of litigation. Such estimates are based on management's judgment which takes into account historical experience and various assumptions. Nonetheless, actual results may differ from management's estimates.

ENDOLOGIX, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(all tabular amounts presented in thousands, except per share, per unit, and number of years)

(Unaudited)

The following accounting policies and estimates were used in the preparation of the accompanying Condensed Consolidated Financial Statements:

(i) Cash and Cash Equivalents and Restricted Cash

The carrying amount of the Company's money market funds is included in cash and cash equivalents in the accompanying Condensed Consolidated Balance Sheets, and approximates its fair value (utilizing Level 1 inputs) because of the ability to immediately convert these money market funds to cash with minimal change in value.

Restricted cash is held as bank deposits, and supports two letters of credit while leasehold improvements are completed for the Company's 2014 corporate headquarters and production facility in Irvine, California. This restricted cash was fully released under the July 26, 2013 amendment to the Wells Credit Facility (see Note 6).

(ii) Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount, inclusive of applicable value-added tax ("VAT"), and do not bear interest. Revenue is recorded net of VAT. The allowance for doubtful accounts is management's best estimate of the amount of probable credit losses in existing accounts receivable. Account balances are charged off against the allowance after appropriate collection efforts are exhausted.

(iii) Inventories

The Company values inventory at the lower of the actual cost to purchase or manufacture the inventory, or the market value for such inventory. Cost is determined on the first-in, first-out method (FIFO). The Company regularly reviews inventory quantities in process and on hand, and when appropriate, records a provision for obsolete and excess inventory. The provision is based on actual loss experience and a forecast of product demand compared to its remaining shelf life.

(iv) Property and Equipment

Property and equipment are stated at cost and depreciated on a straight-line basis over the following estimated useful lives:



	Useful Life
Office furniture	Seven years
Computer hardware	Three years
Computer software	Three to eight years
Production equipment and molds	Three to seven years
Leasehold improvements	Shorter of expected useful life or remaining term of lease

Upon sale or disposition of property and equipment, any gain or loss is included in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).

(v) Goodwill and Intangible Assets

Intangible assets with definite lives are amortized over their estimated useful lives using a method that reflects the pattern over which the economic benefit is expected to be realized, and is as follows:



	Useful Life
Goodwill	Indefinite lived
Trademarks and tradenames	Indefinite lived
In-process research and development	Indefinite lived until commercial launch of underlying technology
Developed technology	Thirteen years
Patents and license	Three to five years
Customer relationships	Three years

Goodwill and other intangible assets with indefinite lives are not subject to amortization, but are tested for impairment annually or whenever events or changes in business circumstances suggest the potential of an impairment.

Table of Contents

ENDOLOGIX, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(all tabular amounts presented in thousands, except per share, per unit, and number of years)

(Unaudited)

The Company completed its annual indefinite lived intangible asset impairment test as of June 30, 2013, with no resulting impairment based on the discounted cash flows expected to be generated by the corresponding intangible assets.

The Company also most recently completed its annual test for impairment of goodwill as of June 30, 2013, with no resulting impairment. The Company's market capitalization was in substantial excess of the value of its total stockholders' equity (the Company has one "reporting unit" for purposes of the goodwill impairment test).

Intangible assets with finite lives are tested for impairment only when impairment indicators are present.

(vi) Fair Value Measurements

The Company applies relevant GAAP in measuring the fair value of its Contingent Payment (see Note 9). Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. GAAP establishes a fair value hierarchy that distinguishes between (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (ii) an entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level 3 - Inputs that are both significant to the fair value measurement and unobservable.

(vii) Contingent Consideration for Business Acquisition

The Company's management determined the fair value of contingently issuable common stock on the Nellix acquisition date (see Note 9) using a probability-based income approach with an appropriate discount rate (determined using both Level 1 and Level 3 inputs). Changes in the fair value of this contingently issuable common stock are determined at each period end and are recorded in the other income (expense) section of the accompanying Condensed Consolidated Statements of Operations and Comprehensive Income (Loss), and the long term liabilities section of the accompanying Condensed Consolidated Balance Sheet.

(viii) Revenue Recognition

The Company recognizes revenue when all of the following criteria are met:

• Appropriate evidence of a binding arrangement exists with the customer;


•	The sales price for the ELG System (including device extensions and accessories) is established with the customer;


•	The ELG System has been used by the hospital in an EVAR procedure, or the distributor has assumed title with no right of return; and

• Collection of the corresponding receivable from the customer is reasonably assured at the time of sale.

For sales made to hospitals, the Company recognizes revenue upon completion of an EVAR procedure, when the ELG Device is implanted in a patient. For sales made to distributors, the Company recognizes revenue when title passes, which is typically at the time of shipment, as this represents the period that the customer has assumed custody of the ELG System, without right of return, and assumed risk of loss.

In the event that the Company enters into a bill and hold arrangement with its customer, which is uncommon, though occurred throughout 2012 for a certain ROW distributor (as discussed in Note 7 to the Company's Annual Report on Form 10-K for the year ended December 31, 2012), the following conditions must be met for revenue recognition:

Table of Contents

ENDOLOGIX, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(all tabular amounts presented in thousands, except per share, per unit, and number of years)

(Unaudited)


(i)	The risks of ownership must have passed to the customer;


(ii)	The customer must have made a fixed and written commitment to purchase the ELG Systems;


(iii)	The customer must request that the transaction be on a bill and hold basis;


(iv)	There must be a fixed schedule for delivery of the ELG Systems. The date for delivery must be reasonable and must be consistent with the customer's business purpose;


(v)	The Company must have no remaining specific performance obligations and its earnings process must be complete;


(vi)	The customer's ordered ELG Systems must be segregated from the Company's inventory and cannot be used to fulfill other customer orders; and


(vii)	The ELG Systems must be complete and ready for shipment.

In addition to the above requirements, the Company also considers other pertinent factors prior to its recognition of revenue for bill and hold arrangements, such as:


(i)	The date by which payment is expected from the customer, and whether the Company has modified its normal billing and credit terms for the customer;


(ii)	The Company's past experiences with, and pattern of, bill and hold transactions;


(iii)	Whether the customer has the expected risk of loss in the event of a decline in the market value of the ELG Systems;


(iv)	Whether the Company's custodial risks are insurable and insured; and


(v)	Whether extended procedures are necessary in order to assure that there are no exceptions to the customer's commitment to accept and pay for the ELG Systems (i.e., that the business reasons for the bill and hold have not introduced a contingency to the customer's commitment).

(ix) Shipping Costs

Shipping costs billed to customers are reported within revenue, with the corresponding costs reported within costs of goods sold.

(x) Foreign Currency Transactions

The assets and liabilities of the Company's foreign subsidiaries are translated at the rates of exchange at the balance sheet date. The income and expense items of these subsidiaries are translated at average monthly rates of exchange. Gains and losses resulting from foreign currency transactions, which are denominated in a currency other than the respective entity’s functional currency are included in other income (expense), net, within the accompanying Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). Foreign currency translation adjustments between the respective entity's functional currency and the U.S. dollar are recorded to accumulated other comprehensive income/(loss) within the stockholders' equity section of the accompanying Condensed Consolidated Balance Sheets. There were no items reclassified out of accumulated other comprehensive income (loss) and into net income (loss) during the three and six months ended June 30, 2013 and 2012.

(xi) Income Taxes

The Company records the estimated future tax effects of temporary differences between the tax basis of assets and

liabilities and amounts reported in the financial statements, as well as operating losses and tax credit carry forwards. The Company has recorded a valuation allowance to fully reduce its net deferred tax assets, because the Company believes that, based upon a number of factors, it is more likely than not that the deferred tax assets will not be realized. If the Company were to determine that it would be able to realize its deferred tax assets in the future, an adjustment to the valuation allowance on its deferred tax assets would increase net income in the period such determination was made. In the event that the Company were assessed interest and/or penalties from taxing authorities, such amounts would be included in "income tax expense" within the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) in the period the notice was received.

(xii) Net Income (Loss) Per Share

Net income (loss) per common share is computed using the weighted average number of common shares outstanding

during the periods presented. Because of the net losses during the six months ended June 30, 2013 and 2012, and the three months ended June, 2012, options to purchase common stock, restricted stock awards, and restricted stock units were excluded from the computation of net loss per share for these periods because its effect would have been antidilutive. Because of the net income for

(all tabular amounts presented in thousands, except per share, per unit, and number of years)

(Unaudited)

the three months ended June 30, 2013, options to purchase common stock, restricted stock awards and restricted stock units were included in the computation of diluted net income per share because its effect is dilutive.

(xiii) Research and Development Costs

Research and development costs are expensed as incurred.

(xiv) Product Warranty

Within six months of shipment, certain customers may request replacement of products they receive that do not meet product specifications; no other warranties are offered. The Company contractually disclaims responsibility for any damages associated with physicians' use of its ELG System. Historically, the Company has not experienced a significant amount of costs associated with its warranty policy.

3. Stock-Based Compensation

The Company classifies stock-based compensation expense in the accompanying Condensed Consolidated Statements of Operations, based on the department to which the recipient belongs. Stock-based compensation expense included in cost of goods sold and operating expenses during the three and six months ended June 30, 2013 and 2012, was as follows:




	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2013		2012		2013		2012
Cost of goods sold	$	227	$	116	$	377	$	204
Operating expenses:
Research and development	191		182		396		333
Clinical and regulatory affairs	35		44		438		78
Marketing and sales	1,087		398		1,665		680
General and administrative	557		604		1,451		1,062
Total operating expenses	$	1,870	$	1,228	$	3,950	$	2,153
Total	$	2,097	$	1,344	$	4,327	$	2,357

4. Net Income (Loss) Per Share

Basic net income (loss) per share was calculated by dividing net income (loss) by the weighted average number of common shares outstanding for the three and six months ended June 30, 2013 and 2012. Diluted net income per share for the three months ended June 30, 2013, was calculated by adjusting outstanding shares for the dilutive effects of outstanding, but unexercised, stock options and unvested restricted stock, as calculated under the treasury stock method.



	Three Months Ended					Six Months Ended
	June 30,					June 30,
	2013		2012			2013			2012
Net income (loss)	$	5,670	$	(6,696	)	$	(3,665	)	$	(23,399	)

Net income (loss) per share- diluted	$	0.09	$	(0.11	)	$	(0.06	)	$	(0.40	)

The following outstanding Company securities were included in the above calculations of net income per share because their impact was dilutive:

6. Credit Facilities

In October 2009, the Company entered into a revolving credit facility with Wells Fargo Bank (“Wells”), which was last amended on July 26, 2013, whereby the Company may borrow up to $20.0 million, subject to the calculation and limitation of a borrowing base (the “Wells Credit Facility”). All amounts owing under the Wells Credit Facility will become due and payable upon its expiration on November 15, 2014.

As of June 30, 2013, the Company did not have any outstanding borrowings under the Wells Credit Facility. Any outstanding amounts under the Wells Credit Facility bear interest at a variable rate equal to the Wells prime rate, plus 1.00%, which is payable on a monthly basis. The Wells Credit Facility carried a 0.2% unused commitment fee though May 19, 2012, when this fee was eliminated. The Wells Credit Facility is collateralized by all of the Company's assets, except its intellectual property.

The Wells Credit Facility contains certain financial covenants requiring the Company in 2013 and 2014 to (i) maintain a minimum quarter-end "current ratio" of current assets to current liabilities; (ii) meet minimum quarterly net operating income (loss) thresholds; and (iii) not exceed an annual limitation on capital expenditures. The Company was in compliance with these covenants for the six months ended June 30, 2013.

The Wells Credit Facility also contains a “material adverse change” clause (“MAC”). If the Company encounters difficulties that would qualify as a MAC in its (i) operations, (ii) condition (financial or otherwise), or (iii) ability to repay amounts outstanding under the Wells Credit Facility, it could be canceled at Wells' sole discretion. Wells could then elect to declare the indebtedness, together with accrued interest and other fees, to be immediately due and payable and proceed against any collateral securing such indebtedness.

7. Revenue by Geographic Region

U.S. The Company's U.S. sales were solely derived from its sales force, divided among twelve geographic sales regions.

Europe. The Company's European sales were derived from (i) its direct European sales force (including dedicated sales agents) serving much of Western Europe, and (ii) six independent distributors serving the markets in Italy (through June 2012), Greece, Sweden, Turkey, Poland, Romania and Ireland.

ROW. The Company's ROW sales were solely derived from independent distributors.

8. Commitments and Contingencies

(a) Leases

The Company leases (i) its administrative, research, and manufacturing facilities in Irvine, California, (ii) its administrative facility in Den Bosch, The Netherlands, and (iii) certain equipment. These agreements are accounted for as operating leases. The Irvine facility lease agreements require the Company to pay operating costs, including property taxes, insurance, and maintenance.

Future minimum payments by year under non-cancelable leases with initial terms in excess of one year were as follows as of June 30, 2013:



Remainder of 2013	$	330
2014	959
2015	2,000
2016	2,060
2017	2,122
2018 and thereafter	28,729
	$	36,200

On June 12, 2013, the Company entered into a lease agreement for two adjacent office, research and development, and manufacturing facilities in Irvine, California. The premises consist of approximately 129,000 combined square feet. The lease has a 15-year term beginning January 1, 2014 and provides for one optional five year extension. The initial base rent under the lease is $1.9 million per year, payable in monthly installments, and escalates by 3% per year for years 2015 through 2019, and 4% per year for years 2020 and beyond. The Company is entitled to rent abatement for the first nine months of the lease. These premises will replace the Company's existing Irvine facilities.

The terms of this lease agreement provide for $6.8 million of landlord-funded improvements (and certain other allowances) to this facility, in order to best suit the Company's requirements. In June 2013, the Company had Wells issue the landlord two letters of credit in the aggregate amount of $5.4 million under its Wells Credit Facility, representing financial collateral while these facility improvements are completed. The Company placed the same amount in a restricted cash account with Wells, in order to fully support these issued, but undrawn, letters of credit. In July 2013, this restricted cash account was fully released under the July 26, 2013 amendment to the Wells Credit Facility.

(b) Employment Agreements and Retention Plan

The Company has entered into employment agreements with its officers and certain other “key employees” under which payment and benefits would become payable in the event of termination by the Company for any reason other than cause, upon a change in control of the Company, or by the employee for good reason. The payment will generally be equal to six months of the employee’s then current salary for termination by the Company without cause and twelve months of salary if upon a change in control of the Company.

The Company from time to time is involved in various claims and legal proceedings of a nature considered normal and incidental to its business. These matters may include product liability, intellectual property, employment, and other general claims. The Company accrues for contingent liabilities when it is probable that a liability has been incurred and the amount can be

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(all tabular amounts presented in thousands, except per share, per unit, and number of years)

(Unaudited)

reasonably estimated. The accruals are adjusted periodically as assessments change or as additional information becomes available.

LifePort

On December 28, 2012, LifePort Sciences, LLC filed a complaint against the Company in the United States District Court, District of Delaware alleging that certain of the Company's products infringe U.S. Patent Nos. 5,489,295, 6,117,167, 6,302,906, 5,993,481 and 5,676,696, which are alleged to be owned by LifePort. LifePort is seeking an unspecified amount of monetary damages for sale of the Company's products. The Company does not believe it infringes on any of these patents and intends to vigorously defend itself in this matter.

At this time, the Company is unable to predict the outcome of this matter, but is of the opinion that the outcome will not have a material adverse effect on its financial position, results of operations, or cash flow. However, in order to avoid further legal costs (recognized within "general and administrative" expenses within the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss)) and diversion of management resources, it is reasonably possible that the Company may reach a settlement with LifePort, which could result in a liability. However, the Company cannot presently estimate the amount, or range, of reasonably possible losses due to the nature of this litigation.

9. Contingently Issuable Common Stock

On December 10, 2010 (the “Nellix Closing Date”), the Company completed its acquisition of Nellix, Inc., a pre-revenue, AAA medical device company. The purchase price consisted of 3.2 million of the Company's common shares, issuable to the former Nellix stockholders as of the Nellix Closing Date, then representing a value of $19.4 million. Additional payments, solely in the form of the Company's common shares (the “Contingent Payment”), will be made upon the achievement of a revenue milestone and a regulatory approval milestone (collectively, the “Nellix Milestones”).

The ultimate value of the Contingent Payment will be determined on the date that each Nellix Milestone is achieved. The number of issuable shares will be established using an applicable per share price, which is subject to a ceiling and/or floor, resulting in a maximum of 10.2 million shares issuable upon the achievement of the Nellix Milestones.

As of the Closing Date, the fair value of the Contingent Payment was estimated to be $28.2 million. As of June 30, 2013, the Company's stock price last closed at $13.28 per share. Thus, had the Nellix Milestones been achieved on June 30, 2013, the Contingent Payment would have comprised 4.3 million shares, representing a value of $57.1 million.

The value of the Contingent Payment is derived using a discounted income approach model, with a range of probabilities and assumptions related to the timing and likelihood of achievement of the Nellix Milestones (which include Level 3 inputs - see Note 2(vi) and the Company's stock price (Level 1 input) as of the balance sheet date). These varying probabilities and assumptions and changes in the Company's stock price have required fair value adjustments of the Contingent Payment in periods subsequent to the Nellix Closing Date.

The per share price of the Company's common stock decreased by $0.96, or 6.7%, between December 31, 2012 and June 30, 2013. The decrease in the value of the Company's common stock was the primary driver affecting the decrease in the fair value of the Contingent Payment during the six months ended June 30, 2013.

The Contingent Payment fair value will continue to be evaluated on a quarterly basis until milestone achievement occurs, or until the expiration of the "earn-out period," as defined within the Nellix purchase agreement. Adjustments to the fair value of the Contingent Payment are recognized within other income (expense) in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).



	Fair Value of Contingently Issuable Common Stock
December 31, 2012	$	52,400
Fair value adjustment of Contingent Payment for six months ended June 30, 2013	(2,400		)
June 30, 2013	$	50,000

10. Income Tax Expense

Table of Contents

ENDOLOGIX, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(all tabular amounts presented in thousands, except per share, per unit, and number of years)

(Unaudited)

The Company applied an estimated annual effective tax rate (“ETR”) approach for calculating a tax provision for interim periods, as required under GAAP. The Company recorded a benefit (provision) for income taxes of $0.1 million and $(0.2) million for the three and six months ended June 30, 2013, respectively. The Company's ETR was 3% and (6)% for the three and six months ended June 30, 2013, respectively. The Company's ETR for the three and six months ended June 30, 2013 differs from the U.S. federal statutory tax rate of 35% primarily as a result of nondeductible expenses (including the Nellix Contingent Payment), state income taxes, foreign income taxes, and the impact of a full valuation allowance on its deferred tax assets.

The Company has evaluated the available evidence supporting the realization of its deferred tax assets, including the amount and timing of future taxable income, and has determined that it is more likely than not that its net deferred tax assets will not be realized in the U.S. and certain foreign jurisdictions. Due to uncertainties surrounding the realization of the deferred tax assets, the Company maintains a full valuation allowance against substantially all deferred tax assets. If/when the Company determines that it will be able to realize some portion or all of its deferred tax assets, an adjustment to its valuation allowance on its deferred tax assets would have the effect of increasing net income in the period(s) such determination is made.

11. Subsequent Events

Dr. Schreck - Leave of Absence

On July 12, 2013, Stefan G. Schreck, Ph.D., Chief Technology Officer, notified the Company that he will be taking a three-month leave of absence, starting August 1, 2013. The Company expects Dr. Schreck to return from the leave of absence in a different capacity with reduced duties and responsibilities. James E. Machek, formerly the Company's Vice President, Research and Development, Nellix Technologies, was promoted to the position of Vice President, Research and Development, effective July 15, 2013, and assumed the duties and responsibilities previously performed by Dr. Schreck.

Sixth Amendment to the Wells Credit Facility

On July 26, 2013, the Company amended its Wells Fargo Credit Facility (see Note 6) which had the effect of releasing the Company's $5.4 million of “restricted cash” presented on its Condensed Consolidated Balance Sheet as of June 30, 2013. These funds will prospectively be included within “cash and cash equivalents” and will be available to support the Company's working capital requirements.

Overview

Our Business

Our corporate headquarters and manufacturing facility is located in Irvine, California. We develop, manufacture, market, and sell innovative medical devices for the treatment of aortic disorders. Our principal product is a stent graft and delivery catheter for the treatment of abdominal aortic aneurysms ("AAA") through minimally-invasive endovascular repair.

Table of Contents

We sell our products through (i) our direct U.S. and European sales forces and (ii) third-party distributors in Europe, Asia, Latin America, and in other parts of the world.

Recent Highlights of Our Product Development Initiatives and Regulatory Approvals

Nellix

We received CE Mark approval of the Nellix System in January 2013. In February 2013, we commenced a limited market introduction of the Nellix System in Europe. We hope to receive investigational device exemption ("IDE") approval from the Food and Drug Administration ("FDA") for the Nellix System by the end of 2013, and hope to receive FDA premarket approval ("PMA") in the U.S. in 2016.

We believe that the Nellix System represents groundbreaking technology for endovascular aneurysm repair ("EVAR") of AAA. Unlike all currently available ELG devices, which leave the AAA sac fully intact, the Nellix System seals the AAA sac with a biostable polymer to reduce endoleaks and secondary interventions.

We believe the other advantages of the Nellix System include: (i) a low profile (17Fr outer diameter), which is beneficial for the delivery of the device; (ii) ease of use and reduced total time of device deployment for physicians; (iii) low expected reintervention rate; and (iv) the potential for reduced requirement of CT scan post-procedure follow up.

PEVAR

In April 2013 we received FDA PMA for a broadened indication for our AFX system to include totally percutaneous endovascular aneurysm repair ("PEVAR") for AAA. We have completed the PEVAR training and certification of our U.S. sales force and clinical specialists. In May 2013, we commenced the training classes for physicians in the U.S. on the PEVAR procedure.

Vascular access for EVAR requires femoral artery exposure (commonly referred to as surgical “cut-down”) of one or both femoral arteries, allowing for safe introduction of ELG systems. Complications from femoral artery exposure in the setting of EVAR is an inherent risk of current surgical practice. PEVAR procedures do not require an open surgical cut-down of either femoral artery, as access to the femoral artery is achieved via a needle-puncture through the skin. Advantages to the patient and to the health care system of an entirely percutaneous procedure include reduced surgical procedure times, less post-operative pain, and fewer access-related wound complications. To date, our ELG System is the only one approved by the FDA specifically for full percutaneous access.

Ventana

Our Ventana fenestrated EVAR (FEVAR) system has been used to treat approximately 120 patients world-wide, including 80 in our U.S. IDE study. In reviewing these first 120 global procedures with Ventana, we have seen good overall safety results, but a higher than expected number of renal re-interventions. We have temporarily suspended further enrollment in the Ventana U.S. IDE study and delayed commercial introduction in Europe until we have an opportunity to fully evaluate physician training, clinical indications, and product enhancements. After completing our evaluation, we will meeting with regulatory

agencies, including the FDA and EU notified bodies. We expect to have an update on our progress and regulatory path toward the end of 2013.

AFX

We plan to commence a limited market introduction of a new aortic extension for the AFX system in the U.S. at the end of 2013. This enhanced device is expected to further simplify the EVAR procedure and provide physicians with improved deployment accuracy.

Characteristics of Our Revenue and Expenses

Revenue

Revenue is derived from sales of our ELG System (including extensions and accessories) to hospitals upon completion of an EVAR procedure, or from sales to distributors upon title transfer (which is typically at shipment), provided our other revenue recognition criteria have been met.

Cost of Goods Sold

Cost of goods sold includes compensation (including stock-based compensation) and benefits of production personnel and production support personnel. Cost of goods sold also includes certain royalty fees to third parties, amortization of our developed technology intangible asset, depreciation expense for production equipment, production materials and supplies expense, allocated facilities-related expenses, and certain direct costs such as shipping.

Research and Development

Research and development expenses consist of compensation (including stock-based compensation) and benefits for research and development personnel, materials and supplies, fees for research and development consultants, outsourced research and development costs, and allocated facilities-related costs. Our research and development activities primarily relate to the development and testing of new devices and methods to treat aortic disorders.

Clinical and Regulatory

Clinical and regulatory expenses consist of compensation (including stock-based compensation) and benefits for clinical and regulatory personnel, regulatory and clinical payments related to studies, and allocated facilities-related costs. Our clinical and regulatory activities primarily relate to studies in order to gain regulatory approval for the commercialization of our devices.

Marketing and Sales

Marketing and sales expenses primarily consist of compensation (including stock-based compensation) and benefits for our sales force, internal sales support functions, and marketing personnel. It also includes costs attributable to marketing our products to our customers and prospective customers.

General and Administrative

General and administrative expenses primarily include compensation (including stock-based compensation) and benefits for personnel that support our general operations such as information technology, executive management, financial accounting, and human resources. General and administrative expenses also include bad debt expense, patent registration fees, legal fees, financial audit fees, insurance costs, recruiting fees, other professional services, the federal Medical Device Excise Tax, and allocated facilities-related expenses.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and the disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the periods presented. While management believes these estimates are reasonable and consistent, they are by their very nature, estimates of amounts that will depend on future events. Accordingly, actual results could differ from these estimates. Our Audit Committee of the Board of Directors periodically reviews our significant accounting policies. Our critical accounting policies arise in conjunction with the following:

•Revenue recognition and accounts receivable

•Inventory - lower of cost or market

•Goodwill and intangible assets - impairment analysis

•Income taxes

•Stock-based compensation

•Contingent consideration for business acquisition

•Litigation accruals

Revenue Recognition and Accounts Receivable

We recognize revenue when all of the following criteria are met:

•We have appropriate evidence of a binding arrangement with our customer;

•The sales price for our ELG System (including extensions and accessories) is established with our customer;

•Our ELG System has been used by the hospital in an EVAR procedure, or our distributor has assumed title

with no right of return, as applicable; and

•Collection from our customer is reasonably assured at the time of sale.

For sales made to a direct customer (i.e., hospitals), we recognize revenue upon completion of an EVAR procedure, when our ELG Device is implanted in a patient. For sales to distributors, we recognize revenue at the time of title transfer, which is typically at shipment. We do not offer any right of return to our customers, other than honoring our standard warranty.

In the event that we enter into a bill and hold arrangement with a customer, which is uncommon, though occurred throughout 2012 for a certain ROW distributor (as discussed in Note 7 to our Annual Report on Form 10-K for the year ended December 31, 2012), the following conditions must be met for revenue recognition:


(i)	The risks of ownership must have passed to the customer;


(ii)	The customer must have made a fixed and written commitment to purchase the ELG Systems;


(iii)	The customer must request that the transaction be on a bill and hold basis;


(iv)	There must be a fixed schedule for delivery of the ELG Systems. The date for delivery must be reasonable and must be consistent with the customer's business purpose;


(v)	We must have no remaining specific performance obligations and its earnings process must be complete;


(vi)	The customer's ordered ELG Systems must be segregated from our inventory and cannot be used to fulfill other customer orders; and


(vii)	The ELG Systems must be complete and ready for shipment.

In addition to the above requirements, we also consider other pertinent factors prior to its recognition of revenue for bill and hold arrangements, such as:


(i)	The date by which payment is expected from the customer, and whether we have modified our normal billing and credit terms for the customer;


(ii)	Our past experiences with, and pattern of, bill and hold transactions;


(iii)	Whether the customer has the expected risk of loss in the event of a decline in the market value of the ELG Systems;


(iv)	Whether our custodial risks are insurable and insured; and


(viii)	Whether extended procedures are necessary in order to assure that there are no exceptions to the customer's commitment to accept and pay for the ELG Systems (i.e., that the business reasons for the bill and hold have not introduced a contingency to the customer's commitment).

Table of Contents

We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to pay amounts due. These estimates are based on our review of the aging of customer balances, correspondence with the customer, and the customer's payment history.

Inventory - Lower of Cost or Market

We adjust our inventory value for estimated amounts of obsolete or unmarketable items. Such assumptions involve projections of future customer demand, as driven by economic and market conditions, and the product's shelf life. If actual demand, or economic or market conditions are less favorable than those projected by us, additional inventory write-downs may be required.

Goodwill and Intangible Assets - Impairment Analysis

Goodwill and other intangible assets with indefinite lives are not subject to amortization, but are tested for impairment annually as of June 30, or whenever events or changes in circumstances indicate that the asset might be impaired. We evaluate the possible impairment (i) if/when events or changes in circumstances occur that indicate that the carrying value of assets may not be recoverable; or (ii) in the case of goodwill and indefinite lived intangible assets, our annual impairment assessment date of June 30.

Income Taxes

Our consolidated balance sheets reflect net deferred tax assets that primarily represent the tax benefit of net operating loss carryforwards and credits and timing differences between book and tax recognition of certain revenue and expense items, net of a valuation allowance. When it is more likely than not that all or some portion of deferred tax assets may not be realized, we establish a valuation allowance for the amount that may not be realized. Each quarter, we evaluate the need to retain all or a portion of the valuation allowance on our net deferred tax assets. Our evaluation considers historical earnings, estimated future taxable income and ongoing prudent and feasible tax planning strategies. Adjustments to the valuation allowance increase or decrease net income or loss in the period such adjustments are made. If our estimates require adjustments, it could have a significant impact on our consolidated financial statements.

Changes in tax laws and rates could also affect recorded deferred tax assets in the future. Management is not aware of any such changes that would have a material effect on our consolidated financial statements.

Stock-Based Compensation

We recognize stock-based compensation expense for employees over the equity award vesting period, based on its fair value at the date of grant. For awards granted to consultants, the award is marked-to-market each reporting period, with a corresponding adjustment to stock-based compensation expense. The fair value of equity awards that are expected to vest is amortized on a straight-line basis over (i) the requisite service period or (ii) the period from grant date to the expected date of the completion of the performance condition for vesting of the award. Stock-based compensation expense recognized is net of an estimated forfeiture rate, which is updated as appropriate.

We use the Black-Scholes option pricing model to value stock option grants. The Black-Scholes option pricing model requires the input of highly subjective assumptions, including the expected volatility of our common stock, expected risk-free interest rate, and the option's expected life.

A portion of restricted stock vesting is dependent on us achieving certain regulatory and financial milestones. We use significant judgment in estimating the likelihood and timing of achieving these milestones. As of each financial statement reporting period, we reassess the likelihood and estimate the timing of reaching these milestones, and will adjust expense accordingly.

Contingent Consideration for Business Acquisition

We determine the fair value of contingently issuable common stock related to the Nellix acquisition using a probability-based income approach using an appropriate discount rate. Changes in the fair value of the contingently issuable common stock are determined each period end and recorded in the other income (expense) section of the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss) and the non-current liabilities section of the Condensed Consolidated Balance Sheet.

Table of Contents

Litigation Accruals

From time to time we are involved in various claims and legal proceedings of a nature considered normal and

incidental to our business. These matters may include product liability, intellectual property, employment, and other general

claims. We accrue for contingent liabilities when it is probable that a liability has been incurred and the amount can

be reasonably estimated. The accruals are adjusted periodically as assessments change or as additional information becomes

available.

	2013		2012		Variance		Percent Change
	(in thousands)
Revenue	$	33,964	$	25,509	$	8,455	33.1%

Our 33.1% revenue increase of $8.5 million over the prior year period primarily resulted from:

(i) a $5.0 million increase in U.S. sales due to (a) the expansion of our U.S. sales force through the addition of sales representatives and clinical specialists (that exclusively provide field support to our sales representatives, increasing overall sales force productivity), and (b) the continued physician adoption of AFX which was launched in the U.S. in August 2011; and

(ii) a $2.2 million increase in European sales due to the expansion of our European sales force (which began direct sales activity in September 2011), and to a lesser extent, the limited market introduction of our Nellix System in February 2013.

Gross margin percentage (gross profit as a percent of revenue)	73.6		%	75.4		%

The $2.7 million increase in cost of goods sold was driven by our revenue increase of $8.5 million.

Gross margin for the three months ended June 30, 2013 decreased to 73.6% from 75.4% for the three months ended

June 30, 2012. This decrease is primarily due to our product mix and the greater proportion of our total revenue being derived from international sales, as well as certain current period charges, aggregating to $1.2 million, to adjust our inventory to its net realizable value.

Contract termination and business acquisition expenses	—		422		(422		)	(100.0	)%

Research and Development. The $1.2 million decrease in research and development expenses was primarily driven by a decrease in Nellix and Ventana development activities. These devices have reached a more mature stage of development as compared to the prior year. The Nellix System has progressed to production and commercialization beginning in February 2013. We temporarily suspended further enrollment in the Ventana U.S. IDE study and delayed its commercial introduction, as previously discussed within the "Recent Highlights of our Product Development Initiatives and Regulatory Approvals" section.

Clinical and Regulatory Affairs. The $0.3 million increase in clinical and regulatory affairs expenses was primarily driven by the continued enrollment and follow-up costs associated with our Ventana U.S. IDE clinical trial and FDA and CE regulatory activities.

Marketing and Sales. The $3.4 million increase in marketing and sales expenses for the three months ended June 30, 2013, as compared to the prior year period, was primarily related to (i) marketing costs to support the growth of our U.S. business; (ii) an increased sales force in the U.S.; and (iii) costs related to the continued growth and development of our direct sales force in Europe.

We expect that sales and marketing expense will remain significantly above prior year amounts due to (i) the continued expansion of our U.S. and European sales forces; (ii) increased activity in U.S. and European trade shows and other marketing initiatives; and (iii) an increase in variable compensation due to our expected sales growth in 2013.

General and Administrative. The $0.5 million increase in general and administrative expenses is primarily attributable to (i) the federal Medical Device Excise Tax (which took effect January 1, 2013), and (ii) increased stock-based compensation expense.

Contract Termination and Business Acquisition Expenses.

Prior period expense of $0.4 million is associated with professional fees incurred as part of the July 2012 acquisition of our Italian distributor's business. This transaction allowed us to begin selling our products through the acquired Italian sales force, and to directly contract with sub-dealers of our products in Italy.

Other Income (Expense), Net. The other income variance of $9.3 million between the three months ended June 30, 2013 and 2012 is primarily related to the fair value adjustment of contingent payment of $7.6 million associated with our acquisition of Nellix (see Note 9). Partially offsetting these fair value adjustments in both periods is the remeasurement of certain assets and liabilities that were not transacted in the functional currency of the corresponding operating entity.

During the three months ended June 30, 2013 and 2012, we had operating legal entities in the U.S., Italy, and the Netherlands (including registered sales branches in certain countries in Europe). We have certain minimum tax liabilities attributable to our operations in these countries and in the U.S.

Our 27.4% revenue increase of $13.7 million over the prior year period primarily resulted from:

(i) a $8.7 million increase in U.S. sales due to (a) the expansion of our U.S. sales force through the addition of sales representatives and clinical specialists (that exclusively provide field support to our sales representatives, increasing overall sales force productivity), and (b) the continued physician adoption of AFX which was launched in the U.S. in August 2011; and

(ii) a $3.9 million increase in European sales due to the expansion of our European sales force (which began direct sales activity in September 2011), and to a lesser extent, the limited market introduction of our Nellix System in February 2013.

Research and Development. The $1.5 million decrease in research and development expenses was primarily driven by a decrease in Nellix and Ventana development activities. These devices have reached a more mature stage of development as compared to the prior year. The Nellix System progressed to the production and commercialization stage beginning in February 2013. We temporarily suspended further enrollment in the Ventana U.S. IDE study and delayed its commercial introduction, as previously discussed within the "Recent Highlights of our Product Development Initiatives and Regulatory Approvals" section.

Clinical and Regulatory Affairs. The $1.3 million increase in clinical and regulatory affairs expenses was primarily driven by the continued enrollment and follow-up costs associated with our Ventana U.S. IDE clinical trial and FDA and CE regulatory activities.

Marketing and Sales. The $5.8 million increase in marketing and sales expenses was primarily related to (i) marketing costs to support the growth of our U.S. business; (ii) an increased sales force in the U.S.; and (iii) costs related to the continued growth and development of our direct sales force in Europe.

General and Administrative. The $1.7 million increase in general and administrative expenses is attributable to (i) the federal Medical Device Excise Tax (which took effect January 1, 2013); (ii) additional personnel to support our business growth; and (iii) increased stock-based compensation expense.

Contract Termination and Business Acquisition Expenses. Prior period expense of $0.4 million is associated with professional fees incurred as part of the July 2012 acquisition of our Italian distributor's business.

Operating Activities

Cash used in operating activities was $1.7 million for the six months ended June 30, 2013, as compared to cash used in operating activities of $11.7 million in the prior year period. The decrease in cash used in operating activities is primarily a function of (i) increased collection levels (notwithstanding the increase in DSO discussed below); (ii) the receipt of a $1.3 million "deemed dividend" from our former products liability carrier; and (iii) a decrease in inventory expenditures as compared to the prior year period.

Table of Contents

During the six months ended June 30, 2013 and 2012, our cash collections from customers totaled $60.1 million and $46.9 million, respectively, representing 94% of reported revenue for the same periods. However, our DSO increased by five days for the period ended June 30, 2013, as compared to the period ended December 31, 2012. A greater proportion of our accounts receivable balance as of June 30, 2013 is comprised of international customers, as opposed to U.S. customers. Our international customers historically have longer collection cycles than our U.S. customers.

Investing Activities

Cash used in investing activities for the six months ended June 30, 2013 was $1.4 million, as compared to cash used in investing activities of $1.0 million in the prior year period, and consisted of (i) machinery and equipment purchases for the production of our ELG Systems; and (ii) expenditures for various information technology enhancements to support our European operations.

Financing Activities

Cash used in financing activities was $2.4 million for the six months ended June 30, 2013, as compared to cash provided by financing activities of $43.7 million in the prior year period. In the current period, $5.4 million was used to fund a restricted cash account to support two outstanding, but undrawn, letters of credit (see Note 11), partially offset by $3.0 million of cash proceeds from the exercise of employee stock options and stock purchases under our employee stock purchase plan. During the six months ended June 30, 2012, the Company received net proceeds of $40.1 million from the private placement of its stock, and $3.5 million of aggregate proceeds from the exercise of employee stock options and stock purchases under our employee stock purchase plan.

Credit Arrangements

See Note 6 to our accompanying Condensed Consolidated Financial Statements.

Credit Risk

The majority of our accounts receivable arise from product sales in the U.S. However, we also have significant

receivable balances from customers within the European Union, Japan, Brazil, Argentina, and Mexico. Our accounts

receivable in the U.S. are primarily due from public and private hospitals. Our accounts receivable outside of the U.S. are

primarily due from independent distributors, and to a lesser extent, public and private hospitals. Our accounts receivable from customers outside of the U.S. is comprised of amounts due from (i) numerous European private and public hospitals, and to lesser extent, though significant, (ii) amounts due from foreign-based distributors.

We monitor the financial performance and credit worthiness of our customers so that we can properly assess

and respond to changes in their credit profile. To determine our allowance for doubtful accounts we consider relevant credit risk factors and other considerations. Our allowance for doubtful accounts of $0.4 million as of June 30, 2013 represents our best estimate of the amount of probable credit losses in our existing accounts receivable.

Future Capital Requirements

We believe that the future growth of our business will depend upon our ability to successfully develop new technologies for the treatment of aortic disorders and successfully bring these technologies to market. We expect to incur significant expenditures in completing product development and clinical trials for our Ventana and Nellix Systems.

The timing and amount of our future capital requirements will depend on many factors, including:


•	the need for working capital to support our sales growth;


•	the need for additional capital to fund future development programs;


•	the need for additional capital to fund our sales force expansion;


•	the need for additional capital to fund strategic acquisitions;


•	our requirements for additional facility space or manufacturing capacity;


•	our requirements for additional information technology infrastructure and systems; and


•	adverse outcomes from potential litigation and the cost to defend such litigation.

We believe that our cash resources are adequate to operate our business for at least the next 12 months. We expect to generate positive cash flows from operation during the second half of 2013. In the event we require additional financing in the future, it may not be available on commercially reasonable terms, if at all. Even if we are able to obtain financing, it may cause substantial dilution (in the case of an equity financing), or may contain burdensome restrictions on the operation of our

Table of Contents

business (in the case of debt financing). If we are not able to obtain required financing, we may need to curtail our operations and/or our planned product development efforts.

Contractual Obligations

See Note 8 to our accompanying Condensed Consolidated Financial Statements.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements (except operating leases) that provide financing, liquidity, market or credit risk support, or involve derivatives. In addition, we have no arrangements that may expose us to liability that are not expressly reflected in the accompanying Condensed Consolidated Financial Statements.

As of June 30, 2013, we did not have any relationships with unconsolidated entities or financial partnerships, often referred to as "structured finance" or "special purpose entities," established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not subject to any material financing, liquidity, market or credit risk that could arise if we had engaged in such relationships.


Item 3.	QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

We do not believe that we currently have material exposure to interest rate, foreign currency exchange rate or other relevant market risks.

Interest Rate and Market Risk. Our exposure to market risk for changes in interest rates relates primarily to the Wells Credit Facility. All outstanding amounts under the Wells Credit Facility bear interest at a variable rate equal to the Wells prime rate, plus 1.00%, which is payable on a monthly basis. As of June 30, 2013, we had no amounts outstanding under the Wells Credit Facility. However, if we draw down the Wells Credit Facility, we may be exposed to market risk due to changes in the rate at which interest accrues.

We do not use derivative financial instruments in our investment portfolio. We are averse to principal loss and try to ensure the safety and preservation of our invested funds by limiting default risk, market risk, and reinvestment risk. We attempt to mitigate default risk by investing in only high credit quality securities and by positioning our portfolio to appropriately respond to a significant reduction in the credit rating of any investment issuer or guarantor. At June 30, 2013, our investment portfolio solely consisted of money market instruments.

Foreign Currency Transaction Risk. We consider our direct exposure to foreign exchange rate fluctuations to be minimal. While a majority of our business is denominated in the United States dollar, a portion of our revenues and expenses are denominated in foreign currencies. Fluctuations in the rate of exchange between the U.S. dollar and the Euro or the British Pound Sterling may affect our results of operations and the period-to-period comparisons of our operating results.


Item 4.	CONTROLS AND PROCEDURES.

We carried out an evaluation, under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report (as directed in Exchange Act Rules 13a-15(e) and 15d-15(e)). Based on that evaluation, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures, as of the end of the period covered by this report, were effective to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our chief executive officer and chief financial officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

There has been no change in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the second quarter of 2013 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Part II. Other Information


Item 1.	LEGAL PROCEEDINGS.

We are from time to time involved in various claims and legal proceedings of a nature considered normal and incidental to our business. These matters may include product liability, intellectual property, employment, and other general claims. We accrue for contingent liabilities when it is probable that a liability has been incurred and the amount can be reasonably estimated. The accruals are adjusted periodically as assessments change or as additional information becomes available.

LifePort

On December 28, 2012, LifePort Sciences, LLC ("LifePort") filed a complaint against us in the United States District Court, District of Delaware alleging that certain of our products infringe U.S. Patent Nos. 5,489,295, 6,117,167, 6,302,906, 5,993,481 and 5,676,696, which are alleged to be owned by LifePort. LifePort is seeking an unspecified amount of monetary damages for the sale of our products. We do not believe we infringe on any of these patents and intend to vigorously defend ourselves in this matter.

At this time, we are unable to predict the outcome of this matter, but are of the opinion that the outcome will not have a material adverse effect on our financial position, results of operations, or cash flow. However, in order to avoid further legal costs (recognized as "general and administrative" expenses within the Consolidated Statements of Operations and Comprehensive Income (Loss)) and diversion of management resources, it is reasonably possible that we may reach a settlement with LifePort, which could result in a liability. However, we cannot presently estimate the amount, or range, of reasonably possible losses due to the nature of this litigation.
