NetScout Systems, Inc.
Notes to Consolidated Financial Statements
(Unaudited)
NOTE 1 – BASIS OF PRESENTATION
The accompanying unaudited interim consolidated financial statements have been prepared by NetScout Systems, Inc., or NetScout or the Company. Certain information and footnote disclosures normally included in financial statements prepared under United States generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). In the opinion of management, the unaudited interim consolidated financial statements include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the Company’s financial position, results of operations and cash flows. The year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The results reported in these unaudited interim consolidated financial statements are not necessarily indicative of results that may be expected for the entire year. All significant intercompany accounts and transactions are eliminated in consolidation.
The accompanying unaudited interim consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. On July 14, 2015, or the Closing Date, the Company completed the acquisition of Danaher Corporation’s (Danaher) Communications Business (Communications Business), which included certain assets, liabilities, technology and employees within Tektronix Communications, VSS Monitoring, Arbor Networks and certain portions of the Fluke Networks Enterprise business, which excluded Danaher’s data communications cable installation business and its communication service provider business (the Comms Transaction). The Comms Transaction is more fully described in Note 7. The Comms Transaction was recorded using the acquisition method of accounting; accordingly, the financial results of the acquisition are included in the accompanying unaudited interim consolidated financial statements for the periods subsequent to the acquisition.
During the second quarter of fiscal year 2017, as part of its continued integration of the Communication Business, the Company realigned its organizational structure. As a result, the Company now accounts for its operations under one operating segment. For additional information, see Note 17 of the Company's Notes to Consolidated Financial Statements.
These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2016 filed with the SEC on May 31, 2016.
Recent Accounting Pronouncements
In August 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2016-15, Classification of Certain Cash Receipts and Cash Payments (ASU 2016-15). ASU 2016-15 is intended to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows and to eliminate the diversity in practice related to such classifications. The guidance in ASU 2016-15 is required for annual reporting periods beginning after December 15, 2017, with early adoption permitted. The Company is currently assessing the potential impact of the adoption of ASU 2016-15 on its consolidated statement of cash flows.
In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (ASU 2016-09), which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU 2016-09 is effective for the Company beginning April 1, 2017. The Company is currently assessing the potential impact of the adoption of ASU 2016-09 on its consolidated financial statements.    
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) Section A - Leases: Amendments to the FASB Accounting Standards Codification (ASU 2016-02), its new standard on accounting for leases. This update requires the recognition of leased assets and lease obligations by lessees for those leases currently classified as operating leases under existing lease guidance. Short term leases with a term of 12 months or less are not required to be recognized. The update also requires disclosure of key information about leasing arrangements to increase transparency and comparability among organizations. ASU 2016-02 is effective for annual reporting periods beginning after December 31, 2018 and interim periods within those fiscal years, and early adoption is permitted. The Company is currently assessing the potential impact of the adoption of ASU 2016-02 on its consolidated financial statements.    
In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09) and issued subsequent amendments to the initial guidance in August 2015, March 2016, April 2016 and May 2016 within ASU 2015-04, 2016-08, ASU 2016-10 and ASU 2016-12, respectively (ASU 2014-09, ASU 2015-04, ASU 2016-08, ASU 2016-10 and ASU 2016-12 collectively, Topic 606). Topic 606 supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of Topic 606 is to recognize revenues when promised goods or services are transferred to customers in an

6

Table of Contents

amount that reflects the consideration that is expected to be received for those goods or services. Topic 606 defines a five-step process to achieve this core principle and, in doing so, it is possible more judgment and estimates may be required within the revenue recognition process than required under existing GAAP, including identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation, among others. Topic 606 will be effective for the Company in the first quarter of its fiscal year 2019. Early adoption is not permitted. The Company is currently assessing the potential impact of the adoption of ASU 2014-09 on its consolidated financial statements.
NOTE 2 – CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS
Financial instruments that potentially subject us to concentration of credit risk consist primarily of investments, trade accounts receivable and accounts payable. The Company's cash, cash equivalents, and marketable securities are placed with financial institutions with high credit standings.
At September 30, 2016 and March 31, 2016, the Company had one direct customer which accounted for more than 10% of the accounts receivable balance, while no indirect channel partner accounted for more than 10% of the accounts receivable balance.
During the three and six months ended September 30, 2016, one direct customer accounted for more than 10% of the Company's total revenue, while no indirect channel partner accounted for more than 10% of total revenue. During the three and six months ended September 30, 2015, one direct customer accounted for more than 10% of the Company's total revenue, while no indirect channel partner accounted for more than 10% of total revenue.
As disclosed parenthetically within the Company's consolidated balance sheet, the Company has a receivable from related parties that represents a concentration of credit risk of $17.5 million and $44.2 million at September 30, 2016 and March 31, 2016, respectively. See Note 19 of the Company's Notes to Consolidated Financial Statements for further information regarding the details of these balances.
Historically, the Company has not experienced any significant failure of its customers' ability to meet their payment obligations nor does the Company anticipate material non-performance by its customers in the future; accordingly, the Company does not require collateral from its customers. However, if the Company’s assumptions are incorrect, there could be an adverse impact on its allowance for doubtful accounts.

NOTE 5 – FAIR VALUE MEASUREMENTS
The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs, and Level 3 includes fair values estimated using significant non-observable inputs. The following tables present the Company’s financial assets and liabilities measured on a recurring basis using the fair value hierarchy at September 30, 2016 and March 31, 2016 (in thousands):

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. On a recurring basis, the Company measures certain financial assets and liabilities at fair value, including marketable securities and derivative financial instruments.
The Company’s Level 1 investments are classified as such because they are valued using quoted market prices or alternative pricing sources with reasonable levels of price transparency.
The Company’s Level 2 investments are classified as such because fair value is being calculated using market observable data for similar but not identical instruments, or a discounted cash flow model using the contractual interest rate as compared to the underlying interest yield curve. The Company's derivative financial instruments consist of forward foreign exchange contracts and are classified as Level 2 because the fair values of these derivatives are determined using models based on market observable inputs, including spot prices for foreign currencies and credit derivatives, as well as an interest rate factor. The Company classifies municipal obligations as level 2 because the fair values are determined using quoted prices from markets the Company considers to be inactive. Commercial paper is classified as Level 2 because the Company uses market

information from similar but not identical instruments and discounted cash flow models based on interest rate yield curves to determine fair value.
The Company's Level 3 asset and liabilities consist of contingently returnable consideration and contingent purchase consideration, respectively. The Company's contingently returnable consideration represents a contingent right of return from Danaher to reimburse NetScout for cash awards to be paid by NetScout to employees of the Communications Business transferred to Newco (as defined below) for post-combination services on various dates through August 4, 2016 as part of the Comms Transaction. The contingently returnable consideration is classified as Level 3 because the fair value of the asset was determined using assumptions developed by management in determining the estimated cash awards expected to be paid on August 4, 2016 after applying an assumed forfeiture rate. The contingently returnable consideration of $11.6 million as of September 30, 2016 is included as prepaid expenses and other current assets in the Company’s consolidated balance sheet. Because the right of offset has not been met, the Company recorded the gross amount of compensation as contingently returnable consideration and the tax benefit of $3.9 million as contingent purchase consideration. The contingent purchase consideration is included as accounts payable in the Company's consolidated balance sheet as of September 30, 2016.
The Company's contingent purchase consideration also includes $660 thousand related to the acquisition of certain assets and liabilities of Avvasi Inc. (Avvasi). The contingent purchase consideration represents amounts deposited into an escrow account, which was established to cover damages NetScout suffers related to any liabilities that NetScout did not agree to assume or as a result of the breach of representations and warranties of the seller as described in the asset purchase agreement. The contingent purchase consideration is included as accrued other in the Company's consolidated balance sheet as of September 30, 2016.
The fair value of contingent purchase consideration related to the acquisition of Simena LLC (Simena) in November 2011 for future consideration to be paid to the former seller is $4.7 million. The contingent purchase consideration is included as contingent liabilities in the Company's consolidated balance sheet.

NOTE 7 - ACQUISITIONS
Avvasi
On August 19, 2016, the Company acquired certain assets and liabilities of Avvasi for $4.6 million. Avvasi’s technology allows service providers to measure, improve and monetize video in their networks. This acquisition builds on the Company's ongoing investment to enhance its service assurance capabilities for video traffic over 4G/LTE networks.
The Company has completed the purchase accounting as of September 30, 2016 related to the Avvasi acquisition.

Of the total consideration, $660 thousand was deposited into an escrow account. The escrow account was established to cover damages NetScout suffers related to any liabilities that NetScout did not agree to assume or as a result of the breach of representations and warranties of the seller as described in the asset purchase agreement. Generally, indemnification claims that Avvasi would be liable for are limited to the total amount of the escrow account and shall be the sole source for the satisfaction of any damages to the Company for such claims, but such limitation does not apply with respect to seller's breach of certain fundamental representations or related to other specified indemnity items, for which certain of Avvasi's shareholders may be liable for additional amounts in excess of the escrow amount. Except to the extent that valid indemnification claims are made prior to such time, the $660 thousand will be paid to the seller on August 21, 2017.
In connection with the Avvasi acquisition, certain former employees of Avvasi will receive cash retention payments subject to such employee's continued employment with the Company through two specified dates: August 21, 2017 and August 20, 2018. The cash retention payment liability was accounted for separately from the business combination as the cash retention payment is automatically forfeited upon termination of employment. The Company will record the liability over the period it is earned as compensation expense for post-combination services.
Goodwill was recognized for the excess purchase price over the fair value of the net assets acquired. Goodwill of $2.0 million from the acquisition was included within the Service Assurance reporting unit. Goodwill and intangible assets recorded as part of the acquisition are deductible for tax purposes.
The fair values of intangible assets were based on valuations using an income approach. These assumptions include estimates of future revenues associated with the technology purchased as part of the acquisition and the migration of the current technology to a more advanced version of the software. This fair value measurement was based on significant inputs not observable in the market and thus represents Level 3 fair value measurements. The following table reflects the fair value of the acquired identifiable intangible assets and related estimates of useful lives (in thousands):

Communications Business
On July 14, 2015 (Closing Date), the Company completed the Comms Transaction, which was structured as a Reverse Morris Trust transaction whereby Danaher contributed its Communications Business to a new subsidiary, Potomac Holding LLC (Newco). The total equity consideration was approximately $2.3 billion based on issuing approximately 62.5 million new shares of NetScout common stock to the existing common unit holders of Newco, based on the July 13, 2015 NetScout common stock closing share price of $36.89 per share. On the Closing Date, the Company did not gain control over certain foreign entities due to regulatory and other compliance requirements (Delayed Close Entities). The Company closed on the acquisition of these Delayed Close Entities on October 7, 2015.
The Comms Transaction was accounted for under the acquisition method of accounting with the operations of the Communications Business included in the Company’s operating results from the relevant date of acquisition. The acquisition method of accounting requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. The determination of the fair value of assets acquired and liabilities assumed has been recognized based on management's estimates and assumptions using the information about facts and circumstances that existed at the acquisition date.
While the Company uses its best estimates and assumptions as part of the purchase price allocation process to value the assets acquired and liabilities assumed on the acquisition date, its estimates and assumptions are subject to refinement. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company's results of operations. The finalization of the purchase accounting assessment may result in a change in the valuation of assets acquired and liabilities assumed. As a result, the Company records adjustments to the assets acquired and liabilities assumed with a corresponding offset to goodwill to reflect additional information received about facts and circumstances which existed at the date of acquisition. The Company records adjustments to the assets acquired and liabilities assumed subsequent to the purchase price allocation period in the Company’s operating results in the period in which the adjustments were determined.
During the period ended September 30, 2016, the Company identified measurement period adjustments that impacted the estimated fair value of the assets and liabilities assumed on July 14, 2015 as a result of new information obtained about the facts and circumstances that existed as of the Closing Date. The table below, which summarizes the allocation of the purchase price for the entities acquired on July 14, 2015, has been updated to reflect these measurement period adjustments. The total measurement period adjustments resulted in a decrease in prepaid expenses and other current assets of $0.2 million, an increase in deferred income taxes of $0.7 million, an increase in deferred tax liabilities of $3.3 million and an overall increase in goodwill of $2.8 million. This change to the provisional amounts of fair value of the assets and liabilities assumed had no impact on the Statement of Operations for the year ended March 31, 2016 or the quarters ended June 30, 2016 and September 30, 2016. The Company has completed the purchase accounting as of September 30, 2016 related to the Comms Transaction.
In connection with the Comms Transaction, under the Employee Matters Agreement dated July 14, 2015 by and among the Company, Danaher and Newco, Danaher will fund certain contracts under which employees will provide post-combination services to the Company.

1)
For any outstanding Danaher restricted stock units or stock options held by employees of the Communications Business transferred to Newco (Newco Employees) that vested from July 14, 2015 through August 4, 2015, the awards continued to vest in Danaher shares. These awards met the definition of a derivative under ASC 815 and as such, the Company determined the fair value of these awards on July 14, 2015 and recorded them separate from the business combination as prepaid compensation. The derivative was amortized into compensation expense through August 4, 2015, the post-combination requisite settlement date. The total amount of compensation expense for post-combination services recorded for the three and six months ended September 30, 2015 was $6.5 million.

2)
All outstanding Danaher restricted stock units or stock options held by Newco Employees that were due to vest after August 4, 2015 were cancelled and replaced by NetScout with a cash retention award equal to one half of the value of the employee’s cancelled Danaher equity award and up to an aggregate of $15 million of restricted stock units relating to shares of NetScout common stock equal to the remaining one half of the value of the employee’s cancelled Danaher equity award. The restricted stock units issued are considered new share-based payment awards granted by NetScout to the former employees of Danaher. NetScout accounted for these new awards separately from the business combination. The Company recognized share-based compensation net of an estimated forfeiture rate and only recognized compensation cost for those shares expected to vest on a straight-line basis over the requisite service period of the award. The cash retention award was paid on August 4, 2016, to those employees that continued their employment with NetScout through the applicable vesting date of August 4, 2016. Danaher will reimburse NetScout for the amount of the cash retention payments (net of any applicable employment taxes and tax deductions). The cash

12

Table of Contents

retention award liability was accounted for separately from the business combination as the cash retention award was automatically forfeited upon termination of employment. NetScout recorded the cash retention award liability over the period it was earned as compensation expense for post-combination services. The reimbursement by Danaher to NetScout of the cash retention award payment represents contingently returnable consideration, which was accounted for separately from the business combination on the date of the acquisition. At September 30, 2016, the Company has recorded a receivable from Danaher in the amount of $11.6 million, and is included as prepaid expenses and other current assets in Company’s consolidated balance sheet. At September 30, 2016, the Company has recorded the tax effect of the cash retention award of $3.9 million, which is included as accounts payable in the Company’s consolidated balance sheet. For the three and six months ended September 30, 2016, $2.6 million and $4.3 million has been recorded as compensation expense for post-combination services. For the three and six months ended September 30, 2015, $2.6 million was recorded as compensation expense for post-combination services.

3)
Newco Employees that were entitled to receive an incentive bonus under the Danaher annual bonus plan and who continued to be employed by NetScout through December 31, 2015 received a cash incentive bonus payment. The cash incentive bonus liability was accounted for separately from the business combination as the cash incentive bonus is automatically forfeited upon termination of employment. NetScout recorded the liability over the period it was earned as compensation expense for post-combination services. The payment of the cash retention award, which was reimbursed by Danaher to NetScout, was accounted for separately from the business combination on the date of the acquisition. For the three and six months ended September 30, 2015, $4.1 million has been recorded as compensation for post-combination services.

4)
Certain Newco Employees received cash retention payments that were subject to the employee’s continued employment with NetScout through October 16, 2015, ninety (90) days after the close of the acquisition. The cash retention payment liability was accounted for separately from the business combination as the cash retention payment was automatically forfeited upon termination of employment. NetScout recorded the liability over the period it was earned as compensation expense for post-combination services. The payment of the cash retention award, which was reimbursed by Danaher to NetScout, was accounted for separately from the business combination on the date of the acquisition. For the three and six months ended September 30, 2015, $6.7 million has been recorded as compensation for post-combination services.

Represents the value of certain outstanding Danaher equity awards held by Newco Employees for which continuing employees received, or will receive value after the Closing Date. A portion of this amount relates to awards that continued to vest in Danaher shares after the Closing Date. These future compensation amounts were settled in shares other than shares of the acquired business. The balance of this amount also represents future compensation expense and relates to cash awards which were paid by NetScout to acquired Newco employees on August 4, 2016. The cash payments by NetScout will be reimbursed by Danaher. These items are further described in the Employee Matters Agreement dated July 14, 2015 by and among NetScout Systems, Inc., Danaher Corporation and Potomac Holding LLC and have been accounted for separately from the Comms Transaction.

Represents the fair value attributable to the Delayed Close Entities that the Company obtained control over on October 7, 2015.
The Comms Transaction was aimed at extending the Company's reach into growth-oriented adjacent markets, including cyber security, with a broader range of market-leading products and capabilities; strengthening the Company's go-to-market resources to better support a larger, more diverse and more global customer base; and increasing scale and elevating the Company's strategic position within key accounts. Goodwill was recognized for the excess purchase price over the fair value of the assets acquired. Goodwill of $1.5 billion from the acquisition was included within the following reporting units: $534.8 million in the Security reporting unit and $976.5 million in the Service Assurance reporting unit. All reporting units resulting from the Comms Transaction will be included in the Company's annual goodwill impairment review.
Goodwill and intangible assets recorded as part of the acquisition are not deductible for tax purposes.
The fair values of intangible assets were based on valuations using an income approach. These assumptions include estimates of future revenues associated with the technology purchased as part of the acquisition and the migration of the current technology to a more advanced version of the software. This fair value measurement was based on significant inputs not observable in the market and thus represents Level 3 fair value measurements. The following table reflects the fair value of the acquired identifiable intangible assets and related estimates of useful lives (in thousands):

NOTE 8 – GOODWILL AND INTANGIBLE ASSETS
Goodwill
We assess goodwill for impairment at the reporting unit level at least annually, or on an interim basis if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value.
Through the first quarter of fiscal year 2017, the Company had five reporting units: (1) legacy NetScout, (2) cybersecurity (Arbor Networks), (3) service assurance product lines focused on the service provider market (formerly known as Tektronix Communications), (4) network visibility product lines (formerly known as VSS Monitoring) and (5) service assurance product lines primarily focused on the enterprise market (formerly known as FNET). As part of its continued integration efforts of the Communication Business acquisition, effective July 1, 2016, the Company reorganized its business units. As a result of this change, the Company reduced the number of reporting units from five reporting units to two reporting units. The two reporting units are: (1) Service Assurance and (2) Security. The former cybersecurity reporting unit was aggregated within the Security reporting unit along with portions of the legacy NetScout business while all other former reporting units were aggregated into the Service Assurance reporting unit. Our reporting units are determined based on the components of our operating segments that constitute a business for which financial information is available and for which operating results are regularly reviewed by segment management.
As a result of the reduction in reporting units, the Company completed a quantitative impairment analysis for goodwill as of July 1, 2016. To conduct the impairment test, the Company performed a quantitative step 1 analysis on a before and after basis and concluded the estimated fair values of each of the Company’s current and former reporting units exceeded their respective carrying values both immediately prior to and subsequent to the change.

16

Table of Contents

The Company determined the fair values of its reporting units by preparing a discounted cash flow analysis using forward looking projections of the reporting units’ future operating results and by comparing the value of the reporting units to the implied market value of selected peers. The significant assumptions used in the discounted cash flow analysis include: revenue and revenue growth, selling margins, other operating expenditures, the discounted rate used to present value future cash flows and terminal growth rates. The discount rate used is a cost of equity method, which is essentially equal to the “market participant” weighted-average cost of capital (WACC). The Service Assurance reporting unit's goodwill fair value substantially exceeded its carrying value. The Security reporting unit's goodwill fair value did not substantially exceed its carrying value. The Company performed a sensitivity analysis on our significant assumptions used to determine the fair value of the Security reporting unit and has determined that a reasonable, negative change in its assumptions, as follows, would not impact our conclusion: decrease projected revenue growth by 2%, decrease selling margin by 4%, decrease the operating margin by 5% or increase the WACC by 200 basis points.
At September 30, 2016, goodwill attributable to our Service Assurance and Security reporting units was $1.2 billion and $548.5 million, respectively. At March 31, 2016, goodwill attributable to our Service Assurance and Security reporting units was $1.2 billion and $547.4 million, respectively. Goodwill is tested for impairment at a reporting unit level at least annually, or on an interim basis if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value.
The change in the carrying amount of goodwill for the six months ended September 30, 2016 is due to the acquisition of Avvasi, purchase accounting adjustments, and the impact of foreign currency translation adjustments related to asset balances that are recorded in currencies other than the U.S. Dollar.

Intangible Assets
The net carrying amounts of intangible assets were $1.0 billion and $1.1 billion at September 30, 2016 and March 31, 2016, respectively. Intangible assets acquired in a business combination are recorded under the acquisition method of accounting at their estimated fair values at the date of acquisition. The Company amortizes intangible assets over their estimated useful lives, except for the acquired trade name which resulted from the Network General Central Corporation (Network General) acquisition, which has an indefinite life and thus is not amortized. The carrying value of the indefinite-lived trade name is evaluated for potential impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired.

NOTE 9 – DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
NetScout operates internationally and, in the normal course of business, is exposed to fluctuations in foreign currency exchange rates. The exposures result from costs that are denominated in currencies other than the U.S. Dollar, primarily the Euro, British Pound, Canadian Dollar, and Indian Rupee. The Company manages its foreign cash flow risk by hedging forecasted cash flows for operating expenses denominated in foreign currencies for up to twelve months, within specified guidelines through the use of forward contracts. The Company enters into foreign currency exchange contracts to hedge cash flow exposures from costs that are denominated in currencies other than the U.S. Dollar. These hedges are designated as cash flow hedges at inception.
All of the Company’s derivative instruments are utilized for risk management purposes, and the Company does not use derivatives for speculative trading purposes. These contracts will mature over the next twelve months and are expected to impact earnings on or before maturity.
The notional amounts and fair values of derivative instruments in the consolidated balance sheets at September 30, 2016 and March 31, 2016 were as follows (in thousands):

NOTE 10 – LONG-TERM DEBT
On July 14, 2015, the Company entered into a certain credit facility with a syndicate of lenders pursuant to a Credit Agreement (Credit Agreement), dated as of July 14, 2015, by and among: the Company; JPMorgan Chase Bank, N.A. (JPMorgan), as administrative agent and collateral agent; J.P. Morgan Securities LLC, KeyBanc Capital Markets, Merrill Lynch, Pierce, Fenner & Smith Incorporated, RBC Capital Markets and Wells Fargo Securities, LLC, as joint lead arrangers and joint bookrunners; Santander Bank, N.A., SunTrust Bank, N.A. and U.S. Bank National Association, as co-documentation agents; and the lenders party thereto. The Credit Agreement provides for a five-year, $800 million senior secured revolving credit facility, including a letter of credit sub-facility of up to $50 million. The Company may elect to use the new credit facility for working capital purposes or repurchase of up to 20 million shares of common stock under the Company's common stock repurchase plan. The commitments under the Credit Agreement will expire on July 14, 2020, and any outstanding loans will be due on that date. At September 30, 2016, $300 million was outstanding under this credit facility.
At the Company’s election, revolving loans under the Credit Agreement bear interest at either (a) an Alternate Base Rate per annum equal to the greatest of (1) JPMorgan’s prime rate, (2) 0.50% in excess of the Federal Funds effective rate, or (3) an adjusted one month LIBOR rate plus 1%; or (b) such adjusted LIBOR rate (for the interest period selected by the Company), in each case plus an applicable margin. For the period from the delivery of the Company's financial statements for the quarter ended June 30, 2016 until the Company has delivered financial statements for the quarter ended September 30, 2016, the applicable margin will be 1.50% per annum for LIBOR loans and 0.50% per annum for Alternate Base Rate loans, and thereafter the applicable margin will vary depending on the Company’s leverage ratio, ranging from 1.00% per annum for Base Rate loans and 2.00% per annum for LIBOR loans if the Company’s consolidated leverage ratio is greater than 2.50 to 1.00, down to 0.25% per annum for Alternate Base Rate loans and 1.25% per annum for LIBOR loans if the Company’s consolidated leverage ratio is equal to or less than 1.00 to 1.00.
The Company’s consolidated leverage ratio is the ratio of its total funded debt compared to its consolidated adjusted EBITDA. Consolidated adjusted EBITDA includes certain adjustments, including, without limitation, adjustments relating to extraordinary, unusual or non-recurring charges, certain restructuring charges, non-cash charges, certain transaction costs and expenses and certain pro forma adjustments in connection with material acquisitions and dispositions, all as set forth in detail in the definition of Consolidated EBITDA in the Credit Agreement.

Table of Contents

Commitment fees will accrue on the daily unused amount of the credit facility. For the period from the delivery of the Company's financial statements for the quarter ended June 30, 2016 until the Company has delivered financial statements for the quarter ended September 30, 2016, the commitment fee will be 0.25% per annum, and thereafter the commitment fee will vary depending on the Company’s consolidated leverage ratio, ranging from 0.35% per annum if the Company’s consolidated leverage ratio is greater than 2.50 to 1.00, down to 0.20% per annum if the Company’s consolidated leverage ratio is equal to or less than 1.00 to 1.00.

Letter of credit participation fees are payable to each lender on the amount of such lender’s letter of credit exposure, during the period from the closing date of the Credit Agreement to but excluding the date which is the later of (i) the date on which such lender’s commitment terminates or (ii) the date on which such lender ceases to have any letter of credit exposure, at a rate per annum equal to the applicable margin for LIBOR loans. Additionally, the Company will pay a fronting fee to each issuing bank in amounts to be agreed to between the Company and the applicable issuing bank.
Interest on Alternate Base Rate loans is payable at the end of each calendar quarter. Interest on LIBOR loans is payable at the end of each interest rate period or at the end of each three-month interval within an interest rate period if the period is longer than three months. The Company may also prepay loans under the Credit Agreement at any time, without penalty, subject to certain notice requirements.
Debt is recorded at the amount drawn on the revolving credit facility plus interest based on floating rates reflective of changes in the market which approximates fair value.
The loans and other obligations under the credit facility are (a) guaranteed by each of the Company’s wholly owned material domestic restricted subsidiaries, subject to certain exceptions, and (b) are secured by substantially all of the assets of the Company and the subsidiary guarantors, including a pledge of all the capital stock of material subsidiaries held directly by the Company and the subsidiary guarantors (which pledge, in the case of any foreign subsidiary, is limited to 65% of the voting stock), subject to certain customary exceptions and limitations. The Credit Agreement generally prohibits any other liens on the assets of the Company and its restricted subsidiaries, subject to certain exceptions as described in the Credit Agreement.
The Credit Agreement contains certain covenants applicable to the Company and its restricted subsidiaries, including, without limitation, limitations on additional indebtedness, liens, various fundamental changes, dividends and distributions, investments (including acquisitions), transactions with affiliates, asset sales, including sale-leaseback transactions, speculative hedge agreements, payment of junior financing, changes in business and other limitations customary in senior secured credit facilities. In addition, the Company is required to maintain certain consolidated leverage and interest coverage ratios. These covenants and limitations are more fully described in the Credit Agreement. At September 30, 2016, the Company was in compliance with all of these covenants.
The Credit Agreement provides that events of default will exist in certain circumstances, including failure to make payment of principal or interest on the loans when required, failure to perform certain obligations under the Credit Agreement and related documents, defaults under certain other indebtedness, certain insolvency events, certain events arising under ERISA, a change of control and certain other events. Upon an event of default, the administrative agent with the consent of, or at the request of, the holders of more than 50% in principal amount of the loans and commitments may terminate the commitments and accelerate the maturity of the loans and enforce certain other remedies under the Credit Agreement and the other loan documents.
In connection with the Company’s new revolving credit facility described above, effective as of the Closing Date, the Company terminated its existing term loan and revolving credit facility pursuant to the Credit and Security Agreement, dated as of November 22, 2011, by and among the Company, KeyBank National Association, as joint lead arranger, sole book runner and administrative agent, Wells Fargo Bank, National Association, as joint lead arranger and co-syndication agent, Merrill Lynch, Pierce, Fenner & Smith Incorporated, as joint lead arranger, Bank of America, N.A., as co-syndication agent, and Silicon Valley Bank and Comerica Bank, as co-documentation agents, and the Lenders party thereto.
The Company capitalized $6.6 million of debt issuance costs associated with the origination of the Credit Agreement, which are being amortized over the life of the revolving credit facility. The unamortized balance was $5.1 million as of September 30, 2016. A balance of $1.4 million is included as prepaid expenses and other current assets and a balance of $3.7 million was included as other assets in Company’s consolidated balance sheet.

In addition, the Company has a contingent liability for $660 thousand related to the acquisition of Avvasi in August 2016 for which an escrow account that was established to cover damages NetScout suffers related to any liabilities that NetScout did not agree to assume or as a result of the breach of representations and warranties of the sellers as described in the asset purchase agreement. Generally, indemnification claims that Avvasi would be liable for are limited to the total amount of the escrow account, which shall be the sole source for the satisfaction of any damages to the Company for such claims, but such limitation does not apply with respect to seller's breach of certain fundamental representations or related to other specified indemnity items, for which certain of Avvasi's shareholders may be liable for additional amounts in excess of the escrow amount. Except to the extent that valid indemnification claims are made prior to such time, the $660 thousand will be paid to the seller on August 21, 2017.
Legal – From time to time, NetScout is subject to legal proceedings and claims in the ordinary course of business. In the opinion of management, the amount of ultimate expense with respect to any current legal proceedings and claims, if determined adversely, will not have a material adverse effect on the Company’s financial condition, results of operations or cash flows.

NOTE 13 – PENSION BENEFIT PLANS
Certain of the Company's non-U.S. employees participate in certain noncontributory defined benefit pension plans acquired in the Comms Transaction. None of the Company's employees in the U.S. participate in any noncontributory defined benefit pension plans. In general, these plans are funded based on considerations relating to legal requirements, underlying asset returns, the plan’s funded status, the anticipated deductibility of the contribution, local practices, market conditions, interest rates and other factors.
The following sets forth the components of the Company's net periodic pension cost of the noncontributory defined benefit pension plans for the three and six months ended September 30, 2016 and 2015 (in thousands):

Expected Contributions
During the six months ended September 30, 2016, the Company made contributions of $112 thousand to its defined benefit pension plans. During the fiscal year ending March 31, 2017, the Company's cash contribution requirements for its defined benefit pension plans are expected to be less than $1.0 million. As a majority of the participants within the Company's plans are all active employees, the benefit payments are not expected to be material in the foreseeable future.
    
Other Matters
Substantially all employees not covered by defined benefit plans are covered by defined contribution plans, which generally provide for company funding based on a percentage of compensation. Expense for all defined contribution plans amounted to $2.4 million, $5.3 million, and $1.5 million and $2.8 million for the three and six months ended September 30, 2016 and 2015, respectively.
NOTE 14 – STOCKHOLDERS EQUITY
On September 20, 2016, the stockholders of the Company approved an amendment to the Third Amended and Restated Certificate of Incorporation to increase the number of authorized shares of common stock, par value $0.001 per share, from 150,000,000 to 300,000,000 shares. The increase in authorized shares of common stock has been reflected in the Company's financial statements.
NOTE 15 – TREASURY STOCK
On April 22, 2014, the Company's board of directors approved a stock repurchase program. This program authorized management to make repurchases of NetScout outstanding common stock of up to $100 million. The Company repurchased 67,752 shares for $2.8 million under this program during the six months ended September 30, 2015. Through July 14, 2015 the Company had repurchased 824,452 shares totaling $34.3 million in the open market under this stock repurchase plan. At March 31, 2016, there were no shares of common stock that remained available to be purchased under this plan due to the approval of a new share repurchase program approved on May 19, 2015.
On May 19, 2015, the Company’s board of directors approved a new share repurchase program, conditional upon the completion of the Comms Transaction. This program enables the Company to repurchase up to 20 million shares of its common stock. This plan became effective on July 14, 2015 upon the completion of the Comms Transaction and replaced the Company's previously existing open market stock repurchase program described above. The Company is not obligated to acquire any specific amount of common stock within any particular timeframe under this program. Through September 30, 2016, the Company has repurchased 13,107,527 shares totaling $376.6 million in the open market under this stock repurchase plan. At September 30, 2016, 6,892,473 shares of common stock remained available to be purchased under the plan. The Company repurchased 3,029,391 shares for $76.6 million under the program during the six months ended September 30, 2016.
In connection with the delivery of common shares upon vesting of restricted stock units, the Company withheld 227,185 shares at a cost of $6.6 million related to minimum statutory tax withholding requirements on these restricted stock units during the six months ended September 30, 2016. These withholding transactions do not fall under the repurchase program described above, and therefore do not reduce the amount that is available for repurchase under that program.

Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares outstanding during the period. Unvested restricted shares, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic earnings per share. Diluted net income (loss) per share is calculated by dividing net income (loss) by the weighted average number of shares outstanding plus the dilutive effect, if any, of outstanding stock options, restricted shares and restricted stock units using the treasury stock method. The calculation of the dilutive effect of outstanding equity awards under the treasury stock method includes consideration of proceeds from the assumed exercise of stock options, unrecognized compensation expense and any tax benefits as additional proceeds. As we incurred a net loss in the six months ended September 30, 2016, all outstanding restricted stock units have an anti-dilutive effect and are therefore excluded from the computation of diluted weighted average share outstanding.
NOTE 17 – INCOME TAXES
The Company's effective income tax rates were 22.1% and 78.1% for the three months ended September 30, 2016 and 2015, respectively. Generally, the effective tax rate differs from the statutory tax rate due to the impact of the domestic production activities deduction, research and development credit, the impact of state taxes and income generated in jurisdictions that have a different tax rate than the U.S. statutory rate. The effective tax rate for the three months ended September 30, 2016 is lower than the effective rate for the three months ended September 30, 2015, primarily due to an increase in the research and development credit (the research and development tax credit was not enacted in the prior period), a change in the jurisdictional mix of earnings and a decrease in non-deductible transaction costs.
The Company's effective income tax rates were 32.8% and 99.0% for the six months ended September 30, 2016 and 2015, respectively. The effective tax rate for the six months ended September 30, 2016 is lower than the effective rate for the six months ended September 30, 2015, primarily due to an increase in the research and development credit (the research and development tax credit was not enacted in the prior period), a change in the jurisdictional mix of earnings and a decrease in non-deductible transaction costs.

NOTE 18 – SEGMENT AND GEOGRAPHIC INFORMATION
As part of its continued integration efforts of the Comms Transaction, effective July 1, 2016, the Company reorganized its business units, which resulted in a change in operating segment composition. As a result of this change, the Company reorganized the number of operating segments from five operating segments to one operating segment. The financial information that is regularly reviewed by the Company's Chief Operating Decision Maker (CODM) to allocate resources and assess performance was changed during the second quarter of fiscal year 2017. Our operating segments are determined based on the units that constitute a business for which financial information is available and for which operating results are regularly reviewed by segment management. The Company reports revenue and income in one reportable segment.
The Company manages its business in the following geographic areas: United States, Europe, Asia and the rest of the world. In accordance with United States export control regulations, the Company does not sell or do business with countries subject to economic sanctions and export controls.

The United States revenue includes sales to resellers in the United States. These resellers fulfill customer orders and may subsequently ship the Company’s products to international locations. The Company reports these shipments as United States revenue because the Company ships the products to a United States location. A majority of revenue attributable to locations outside of the United States is a result of export sales. Substantially all of the Company’s identifiable assets are located in the United States.
NOTE 19 - RELATED PARTY TRANSACTIONS
During our fiscal year ended March 31, 2016 and the three months ended June 30, 2016, a member of the Company’s Board of Directors served as an executive officer of Danaher. As part of the split off of Danaher’s Communications Business and the Company’s subsequent acquisition of that business from Newco's shareholders, NetScout has entered into multiple transactions with Danaher which include: transition services agreements, lease agreements, closing agreements, and compensation for post-combination services provisions within the separation and distribution agreement. This board member is now the founding President and CEO of Fortive Corporation (Fortive), which spun off of Danaher in July 2016. As part of the spin off of Fortive, the transition services agreement was amended to, among other things, assign Danaher's rights, duties, obligations and liabilities under the transition services agreement to Fluke Corporation, a subsidiary of Fortive. The Company has disclosed the transactions with Danaher and Fortive parenthetically within the financial statements.

A member of the Company’s Board of Directors served as a member of the board of directors for EMC Corporation (EMC) during the three and six months ended September 30, 2016, and therefore, the Company considers sales to EMC to be a related party transaction. During the quarter EMC was acquired by Dell Technologies and EMC's board members resigned. The Company will continue to report the wind down of preexisting transactions as related party transactions through the

Company's fiscal year 2017. The Company recognized $107 thousand and $346 thousand in revenue from EMC during the six months ended September 30, 2016 and 2015 in the ordinary course of business.
A member of the Company’s Board of Directors also serves as a consultant for The MITRE Corporation (MITRE) and therefore, the Company considers sales to MITRE to be a related party transaction. The Company generated $22 thousand and $0 in revenue from MITRE during the six months ended September 30, 2016 and 2015 in the ordinary course of business.
During our fiscal year ended March 31, 2016, the Company had a member of the Board of Directors who served as a Section 16 officer of State Street Corporation (State Street) and therefore, the Company considered sales to State Street to be a related party transaction. The Company recognized $122 thousand in revenue from State Street during the six months ended September 30, 2015 in the ordinary course of business. This board member is no longer a Section 16 officer of State Street, and as a result, State Street is no longer considered a related party in the Company's fiscal year ended March 31, 2017.

Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview
We are an industry leader for real-time operational intelligence and performance analytics for service assurance and cyber security solutions that are used in many of the most demanding service provider, enterprise and government networks. Our solutions, based on proprietary Adaptive Service Intelligence (ASI) technology, help customers continuously monitor the service delivery environment to identify performance issues and to provide insight into network-based security threats. As a result, customers can quickly resolve issues that cause business disruptions or that adversely impact the user experience. We manufacture and market these products for integrated hardware and software solutions and are also well positioned to help customers deploy our software in commercial-off-the-shelf hardware and in virtualized form factors. Regardless of the platform, customers use our solutions to help drive return on investment on their network and broader information technology (IT) initiatives while reducing the tangible risks associated with downtime, poor service quality and compromised security.
We have been a technology innovator for three-plus decades since our founding in 1984. Our solutions change how organizations manage and optimize the delivery of business applications and services, assure user experience across global internet protocol (IP) networks and help protect networks from unwanted security threats. Through both internal development and acquisitions, we have continually enhanced and expanded our product portfolio to meet the evolving needs of customers worldwide. Our software analytics capture and transform terabytes of network traffic data in real time into high value, actionable information that enables customers to optimize network performance, manage applications, enhance security and gain insight into the end-user experience.
Our mission is to enable enterprise and service providers to realize maximum benefit with minimal risk from technology advances, like IP convergence, network function virtualization (NFV), software defined networking (SDN), virtualization, cloud, mobility, bring your own device (BYOD), web and the evolving Internet by managing the inherent complexity in a cost-effective manner. Our ASI technology, which we have developed in support of this mission, has the potential of not only expanding our leadership in our core markets, but can also serve as the underlying technology platform that can extend use of our solutions across our global customer base.
Our operating results are influenced by a number of factors, including, but not limited to, the mix and quantity of products and services sold, pricing, costs of materials used in our products, growth in employee-related costs, including commissions, and the expansion of our operations. Factors that affect our ability to maximize our operating results include, but are not limited to, our ability to introduce and enhance existing products, the marketplace acceptance of those new or enhanced products, continued expansion into international markets, development of strategic partnerships, competition, successful acquisition integration efforts, and our ability to achieve expense reductions and make structural improvements in the current economic conditions.
On July 14, 2015, we completed the Comms Transaction, which was structured as a Reverse Morris Trust transaction whereby Danaher contributed the Communications Business to Newco. The total equity consideration was approximately $2.3 billion based on issuing approximately 62.5 million new shares of NetScout common stock to the existing holders of common units of Newco, based on the July 13, 2015 NetScout common stock closing share price of $36.89 per share. The Comms Transaction was aimed at extending NetScout's reach into growth-oriented adjacent markets, including cyber security, with a broader range of market-leading products and capabilities; strengthening its go-to-market resources to better support a larger, more diverse and more global customer base; and increasing NetScout's scale and elevating its strategic position within key accounts. For additional information regarding the Comms Transaction, see Note 7 of our Notes to Consolidated Financial Statements.
On August 19, 2016, we acquired certain assets and liabilities of Avvasi for $4.6 million. Avvasi’s technology allows service providers to measure, improve and monetize video in their networks. This acquisition builds on NetScout's ongoing investment to enhance its service assurance capabilities for video traffic over 4G/LTE networks. For additional information regarding the Avvasi acquisition, see Note 7 of our Notes to Consolidated Financial Statements.
During the second quarter of fiscal year 2017, as part of our continued integration efforts of the Comm Transaction, we reorganized our business units. As a result, we now account for our operations under one reportable segment.
On September 20, 2016, NetScout's stockholders approved an amendment to the Third Amended and Restated Certificate of Incorporation to increase the number of authorized shares of common stock, par value $0.001 per share, from 150,000,000 to 300,000,000 shares. The increase in authorized shares of common stock has been reflected in our financial statements.

Results Overview
We continued to navigate through challenging market conditions, which have primarily impacted sales with service provider customers. Revenue during the three months ended September 30, 2016 benefited from the incremental revenue from the acquisition of the Danaher Communications Business. Our business has maintained strong gross profit margins and income from operations improved due in part to the combination of prudent investment and decreased costs related to the Transaction when compared to the three months ended September 30, 2015.
We continue to maintain strong liquidity. At September 30, 2016, we had cash, cash equivalents and marketable securities (current and non-current) of $303.4 million and $500 million available under our credit facility. The cash, cash equivalents and marketable securities balance represents a decrease of $48.7 million from March 31, 2016, which reflects $76.6 million of cash used to repurchase shares of our common stock, $15.7 million of cash used for capital expenditures and $4.6 million of cash used in the Avvasi acquisition during the six months ended September 30, 2016. These decreases were partially offset by cash provided by operations of $53.6 million during the six months ended September 30, 2016.
Use of Non-GAAP Financial Measures

We supplement the United States generally accepted accounting principles (GAAP) financial measures we report in quarterly and annual earnings announcements, investor presentations and other investor communications by reporting the following non-GAAP measures: non-GAAP total revenue, non-GAAP product revenue, non-GAAP service revenue, non-GAAP income from operations, non-GAAP operating margin, non-GAAP EBITDA from operations, non-GAAP EBIDTA from operations margin, non-GAAP net income, and non-GAAP net income per share (diluted). Non-GAAP revenue eliminates the GAAP effects of acquisitions by adding back revenue related to deferred revenue revaluation and the amortization o
