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 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, we completed the acquisition of the Communications Business (the Communications Business) of Danaher Corporation (Danaher) which is more fully described in Note 7 below. This transaction was recorded using the acquisition method of accounting; accordingly, the financial results of the acquisition are included in the accompanying unaudited consolidated financial statements for the periods subsequent to the acquisition.

These 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, 2015.

Fiscal Year End

The fiscal year end of NetScout and the entities acquired as part of the Communications Business ends on March 31st. Netscout’s quarters end on the last calendar day of the months of June, September and December. The fiscal year 2016 quarter end dates of the entities acquired as part of the Communications Business are October 2nd and December 31st. The Company does not adjust for the difference in fiscal periods between the acquired entities and itself, as such difference would be less than 93 days, pursuant to Regulation S-X Rule 3A-02. References herein to Fiscal 2016, 2015 and 2014 refer to the fiscal years ended March 31, 2016, 2015 and 2014, respectively.

Recent Accounting Pronouncements

In November 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2015-17, Balance Sheet Classification of Deferred Taxes, (ASU 2015-17), which eliminates the current requirement to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, entities will be required to classify all deferred tax assets and liabilities as noncurrent. The Company adopted this standard prospectively in the third quarter of fiscal year 2016 as early adoption was permitted and prior periods were not retrospectively adjusted.

In September 2015, the FASB issued ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, (ASU 2015-16), which eliminates the requirement to restate prior financial statements for measurement period adjustments. The new guidance requires that the cumulative impact of a measurement period adjustment be recognized in the reporting period in which the adjustment is identified. The Company adopted this standard in the second quarter of fiscal year 2016 as early adoption was permitted.

In August 2015, the FASB issued ASU 2015-15, Interest-Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-Of-Credit Arrangements and Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (ASU 2015-15). The guidance in the previously issued ASU 2015-03, Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs does not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company adopted this standard in the second quarter of fiscal year 2016 as early adoption was permitted.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 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. This ASU will be effective for the Company in the first quarter of its fiscal year 2019. Early adoption is not permitted. This ASU allows for either full retrospective or modified retrospective adoption. The Company is currently evaluating the impact of its pending 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 December 31, 2015, no direct customer or indirect channel partner accounted for more than 10% of the accounts receivable balance. At March 31, 2015, one direct customer 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 nine months ended December 31, 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 for such periods.

During the three and nine months ended December 31, 2014, no direct customer or indirect channel partner accounted for more than 10% of the Company's total revenue.

As disclosed parenthetically within the Company's consolidated balance sheet, the Company has a receivable from Danaher in the amount of $28.7 million that represents a concentration of credit risk at December 31, 2015.

Historically, the Company has not experienced any significant failure of its customers 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 December 31, 2015 and March 31, 2015 (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 data from similar but not identical sources, 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. For further information on the Company's derivative instruments refer to Note 9.

The Company's Level 3 asset and liability 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 acquisition of the Communications Business. The contingently returnable consideration is classified as Level 3 because the fair

Table of Contents

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 $16.7 million, net of taxes as of December 31, 2015 is included as prepaid expenses and other current assets in the Company’s consolidated balance sheet. During the three months ended December 31, 2015, certain post combination cash retention payments have been disbursed. Danaher will reimburse the Company for those costs and NetScout will reimburse Danaher for the tax benefit. 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 $2.6 million as contingent purchase consideration. For additional information, see Note 7 of the Company's Notes to Consolidated Financial Statements.

The following table sets forth a reconciliation of changes in the fair value of the Company’s Level 3 financial assets and liabilities for the nine months ended December 31, 2015 (in thousands):



	Contingent Purchase Consideration			Contingently Returnable Consideration
Balance at beginning of period	$	(4,484	)	$	—
Increase in fair value and accretion expense (included within research and development expense)	(114		)
Contingently returnable consideration				19,125
Increase in fair value				3,676

Payment received				(8,750		)
Balance at end of period	$	(7,234	)	$	16,687

Deal related compensation expense and accretion charges related to the contingent consideration for the nine months ended December 31, 2015 was $114 thousand and was included as part of earnings.

NOTE 6 – INVENTORIES

Inventories are stated at the lower of actual cost or net realizable value. Cost is determined by using the first in, first out (FIFO) method. Inventories consist of the following (in thousands):



	December 31, 2015		March 31, 2015

NOTE 7 - ACQUISITIONS

On July 14, 2015 (Closing Date), the Company completed the acquisition of the 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 acquisition was structured as a Reverse Morris Trust transaction (the 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 Transaction is being 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 preliminary determination of the fair value of assets acquired and liabilities assumed has

Table of Contents

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 will result in a change in the valuation of assets acquired and liabilities assumed and may have a material impact on the Company's results of operations and financial position. As a result, during the measurement period, which may be up to one year from the acquisition date, 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. The size and breadth of the Transaction will necessitate the use of this measurement period to adequately analyze and assess a number of the factors used in establishing the fair value of certain tangible and intangible assets acquired and liabilities assumed as of the acquisition date and the related tax impacts of any changes made. Any potential adjustments made could be material in relation to the preliminary values presented below. During the three months ended December 31, 2015, 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 acquisition 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 an increase in equity consideration for replacement awards of $3.7 million, an increase in accounts receivable of $0.4 million, an increase in inventory of $0.2 million, a decrease in prepaid expenses and other assets of $0.4 million, an increase in property, plant and equipment of $0.3 million, an increase in accounts payable of $0.1 million, an increase in accrued expenses of $0.4 million, a decrease in deferred revenue of $6.3 million and an overall decrease in goodwill of $10.0 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 period ended September 30, 2015 or December 31, 2015.

During the three months ended December 31, 2015, the Company determined that the accounts receivable, accounts payable, accrued expenses and goodwill balances of the acquired entities reported in the Company’s unaudited interim consolidated financial statements for the period ended September 30, 2015 were overstated and deferred revenue was understated. The affected balances were revised in the unaudited interim consolidated financial statements for the period ended December 31, 2015. These revisions correct the immaterial errors identified. The revision resulted in accounts receivable decreasing by $0.1 million, accounts payable decreasing by $0.7 million, accrued expenses decreasing by $3.9 million, deferred revenue increasing $1.5 million and an overall decrease in goodwill of $3.0 million. There was no impact to the Statement of Operations for the period ended September 30, 2015 or December 31, 2015.

In connection with the 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.

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 nine months ended December 31, 2015 was $0.0 million and $6.5 million, respectively.

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 $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

Table of Contents

award. The cash retention award will become payable on the August 4, 2016, subject to the employee’s continued 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 retention award liability will be accounted for separately from the business combination as the cash retention award is automatically forfeited upon termination of employment. NetScout will record the cash retention award liability over the period it is earned as compensation expense for post combination services. The reimbursement by Danaher to NetScout of the estimated cash retention award payment represents contingently returnable consideration, which will be accounted for separately from the business combination on the date of the acquisition. At December 31, 2015, the Company has recorded a receivable from Danaher in the amount of $8.4 million, net of tax and is included as prepaid expenses and other current assets in Company’s consolidated balance sheet. At December 31, 2015, the Company has recorded a cash retention award liability of $5.4 million and is included as accrued compensation in Company’s consolidated balance sheet. For the three and nine months ended December 31, 2015, $2.8 million and $5.4 million has been recorded as compensation expense for post combination services, respectively.

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 will receive a cash incentive bonus payment. The cash incentive bonus liability will be accounted for separately from the business combination as the cash incentive bonus is automatically forfeited upon termination of employment. NetScout will record the liability over the period it is earned as compensation expense for post combination services. The payment of the cash retention award is reimbursable by Danaher to NetScout, which is accounted for separately from the business combination on the date of the acquisition. At December 31, 2015, the Company has a receivable due from Danaher in the amount of $556 thousand and is included as prepaid expenses and other current assets in the Company’s consolidated balance sheet. At December 31, 2015, the Company has recorded a cash incentive bonus liability of $9.3 million and is included as accrued compensation in the Company’s consolidated balance sheet. For the three and nine months ended December 31, 2015, $5.2 million and $9.3 million has been recorded as compensation expense for post combination services.

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 will be accounted for separately from the business combination as the cash retention payment 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 will be reimbursed by Danaher to NetScout, which will be accounted for separately from the business combination on the date of the acquisition. At December 31, 2015, the Company has recorded a receivable due from Danaher in the amount of $7.8 million, and is included as prepaid expenses and other current assets in Company’s consolidated balance sheet. At December 31, 2015, the Company has recorded the tax effect of the cash retention award of $2.6 million, which is included as accounts payable in the Company’s consolidated balance sheet. For the three and nine months ended December 31, 2015, $1.1 million and $7.8 million has been recorded as compensation expense for post combination services, respectively.

	(1)	Represents approximately 62.5 million new shares (plus cash in lieu of fractional shares) of NetScout common stock issued 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, less the fair value attributable to the foreign entities that the Company did not obtain control over on July 14, 2015 due to regulatory and other compliance requirements.



	(2)	Represents the value of certain outstanding Danaher equity awards held by Newco Employees for which continuing employees will receive value after the Closing Date. A portion of this amount relates to awards that will continue to vest in Danaher shares after the Closing Date. These future compensation amounts will be 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 to be 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 Communications Business Acquisition.

(1	)	Represents the fair value attributable to the Delayed Close Entities that the Company obtained control over on October 7, 2015.

The Transaction is expected to extend the Company's reach into growth-oriented adjacent markets, including cyber security, with a broader range of market-leading products and capabilities, strengthen the Company's go-to-market resources to better support a larger, more diverse and more global customer base, and increase scale and elevate 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 will be included within the following operating segments: $533.1 million in Arbor Networks, $784.8 million in Tektronix Communications, $57.0 million in VSS, and $121.5 million in FNET. All reporting units resulting from the 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 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):



	Fair Value		Useful Life (Years)
Developed technology	$	221,900	9 - 13
Customer relationships	794,100		13 - 18
Backlog	18,200		1 - 3
Definite lived trademark and tradenames	43,900		3 - 9
Leasehold interest	2,600		4 - 6
	$	1,080,700

The weighted average useful life of identifiable intangible assets acquired in the transaction is 14.7 years. Developed technology is amortized using an accelerated amortization method and has a weighted average useful life of 11.7 years. Customer relationships are amortized using an accelerated amortization method and have a weighted average useful life of 16.3 years. Backlog is amortized using an accelerated amortization method and has a weighted average useful life of 2.0 years. Trademarks and tradenames are

Table of Contents

amortized using an accelerated amortization method and has a weighted average useful life of 8.5 years. Leasehold interests are amortized on a straight-line basis and has a weighted average useful life of 5.6 years.

The Company incurred approximately $23.7 million of acquisition-related costs related to the transaction during the nine months ended December 31, 2015.

During the nine months ended December 31, 2015, the Company has recorded $331.5 million of revenue and a net loss of $49.1 million directly attributable to the Transaction within its consolidated financial statements.

NOTE 8 – GOODWILL AND INTANGIBLE ASSETS

Goodwill

The Company has five operating segments: (1) legacy NetScout, (2) Arbor Networks, (3) Tektronix Communications, (4) VSS and (5) FNET. At December 31, 2015 and March 31, 2015, goodwill attributable to the legacy NetScout reporting unit was $197.5 million and $197.4 million, respectively. Goodwill attributable to the newly acquired Arbor Networks, Tektronix Communications, VSS and FNET operating segments were $533.1 million, $784.8 million, $57.0 million, and $121.5 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 nine months ended December 31, 2015 is due to the acquisition of the Communications Business of Danaher, deferred revenue adjustments, change in assumptions for assumed liabilities and the impact of foreign currency translation adjustments related to asset balances that are recorded in currencies other than the U.S. Dollar.

The net carrying amounts of intangible assets were $1.1 billion and $50.2 million at December 31, 2015 and March 31, 2015, 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.

Intangible assets include the indefinite lived trade name with a carrying value of $18.6 million and the following amortizable intangible assets at December 31, 2015 (in thousands):

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.

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 $800,000,000 senior secured revolving credit facility, including a letter of credit sub-facility of up to $50,000,000. 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.

Subsequent to entering into the Credit Agreement, the Company drew down $250 million to support general working capital requirements as well as to help finance the repurchase of the Company's common stock under its authorized 20 million share common stock repurchase plan. At December 31, 2015, $250 million was outstanding under this credit facility.

At the Company’s election, revolving loans under the Credit Agreement bear interest at either (a) a 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 LIBO rate plus 1%; or (b) such adjusted LIBO rate (for the interest period selected by the Company), in each case plus an applicable margin. For the initial period until the Company has delivered financial statements for the quarter ended March 31, 2016, the applicable margin will be 1.75% per annum for LIBOR loans and 0.75% 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.

Commitment fees will accrue on the daily unused amount of the credit facility. For the initial period until the Company has delivered financial statements for the quarter ended March 31, 2016, the commitment fee will be 0.30% 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.

Table of Contents

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 December 31, 2015, 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 $6.1 million as of December 31, 2015. The balance of $1.4 million is included as prepaid expenses and other current assets and a balance of $4.7 million was included as other assets in Company’s consolidated balance sheet.

NOTE 11 – COMMITMENTS AND CONTINGENCIES

Acquisition related – The Company has one contingent liability related to the acquisition of Simena, LLC (Simena) in November 2011 for future consideration to be paid to the former seller which had an initial fair value of $8.0 million at the time of acquisition. At December 31, 2015, the present value of the future consideration was $4.6 million.

The Company has one contingent liability related to the acquisition of the Communications Business of Danaher in July 2015 and represents the tax effected portion of the contingently returnable consideration. At December 31, 2015, the fair value of the future consideration to be paid to Danaher was $2.6 million. For additional information, see Note 7 of the Company's Notes to consolidated Financial Statements.

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 significant adverse effect on the Company’s financial condition, results of operations or cash flows.

NOTE 12 – PENSION BENEFIT PLANS

Certain of the Company's non-U.S. employees participate in certain noncontributory defined benefit pension plans acquired in the Communications Business acquisition. 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.

Table of Contents

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 nine months ended December 31, 2015 (in thousands):



	Three Months Ended				Nine Months Ended
	December 31,				December 31,
	2015		2014		2015		2014
Service cost	$	49	$	—	$	98	$	—
Interest cost	75		—		150		—
Amortization of net loss	80		—		160		—
Net periodic pension cost	$	204	$	—	$	408	$	—

Expected Contributions

During the nine months ended December 31, 2015, the Company did not make any contributions to its defined benefit pension plans. During the fiscal year ending March 31, 2016, the Company's cash contribution requirements for its defined benefit pension plans are expected to be less than $1.0 million. As 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 benefit pension and defined contribution plans amounted to $2.3 million and $5.1 million for the three and nine months ended December 31, 2015, respectively.

NOTE 13 – TREASURY STOCK

On April 22, 2014, the Company's board of directors approved a stock repurchase program. This program authorized management to make additional repurchases of NetScout outstanding common stock of up to $100 million. Through December 31, 2015, the Company had repurchased 824,452 shares totaling $34.3 million in the open market under this stock repurchase plan. The Company repurchased 67,752 shares for $2.8 million under this program during the nine months ended December 31, 2015. At December 31, 2015, 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 Company's acquisition of the Communications Business. 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 Transaction and replaced the Company's previously existing open market stock repurchase program described above. For additional information regarding the acquisition of the Communications Business, see Note 7 above. Through December 31, 2015, the Company has repurchased 5,196,596 shares totaling $201.0 million in the open market under this stock repurchase plan. At December 31, 2015, 14,803,404 shares of common stock remained available to be purchased under the plan.

In connection with the vesting and release of the restriction on previously vested shares of restricted stock units, the Company withheld 235,816 shares at a cost of $8.6 million related to minimum statutory tax withholding requirements on these restricted stock units during the nine months ended December 31, 2015. 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.

Diluted net income (loss) per share	$	(0.25	)	$	0.42	$	(0.32	)	$	0.97

The following table sets forth restricted stock units excluded from the calculation of diluted net income (loss) per share, since their inclusion would be antidilutive (in thousands):



	Three Months Ended		Nine Months Ended
	December 31,		December 31,
	2015	2014	2015	2014
Restricted stock units	358	19	503	12

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.

NOTE 15 – INCOME TAXES

The Company's effective income tax rates were 3,670.3% and 35.7% for the three months ended December 31, 2015 and 2014, 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 December 31, 2015 is higher than the effective rate for the three months ended December 31, 2014 primarily related to a decrease in profit before taxes due to Transaction related expenses recorded in the quarter, increased research and development credits attributable to acquired companies and a change in the jurisdictional mix of earnings.

Our effective tax rates were 1.0% and 37.9% for the nine months ended December 31, 2015 and 2014, respectively. The effective tax rate is lower than the comparable period in the prior year primarily due to the decrease in profit before taxes due to Transaction related expenses recorded in the first nine months of fiscal year 2016, an increase in research and development tax credits attributable to acquired companies and a change in the jurisdictional mix of earnings.

NOTE 16 – SEGMENT AND GEOGRAPHIC INFORMATION

The Company reports revenues and income under five operating segments that aggregate under 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.

Total revenue by geography is as follows (in thousands):



	Three Months Ended				Nine Months Ended
	December 31,				December 31,
	2015		2014		2015		2014
United States	$	206,899	$	88,905	$	480,341	$	254,260
Europe	50,765		16,981		99,003		37,032

	$	307,679	$	122,833	$	669,532	$	334,284

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 since 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 17 - RELATED PARTY TRANSACTIONS

A member of the Company’s Board of Directors serves as an executive officer (under Section 16 of the Securities Exchange Act of 1934, as amended (the Exchange Act)) 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: transitions services agreements, lease agreements, closing agreements, and compensation for post combination services provisions within the separation and distribution agreement. The Company has disclosed these transactions parenthetically within the financial statements.

A member of the Company’s Board of Directors serves as a member of the board of directors for EMC, Corp. (EMC) and therefore, the Company considers sales to EMC to be a related party transaction. The Company recognized $409 thousand in revenue from EMC during the nine months ended December 31, 2015 in the ordinary course of business. Another member of the Company’s Board of Directors also serves as a Section 16 officer of State Street Corporation (State Street) and therefore, the Company considers sales to State Street to be a related party transaction. The Company recognized $254 thousand in revenue from State Street during the nine months ended December 31, 2015 in the ordinary course of business.

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 a gateway for future intelligence solutions including cyber and business intelligence.

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, our ability to achieve expense reductions and make structural improvements and current economic conditions.

On July 14, 2015, we completed the acquisition of the 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 Transaction was structured as a Reverse Morris Trust transaction whereby Danaher Corporation 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. The Transaction is expected to more than double NetScout's total addressable market to over $8 billion by extending its reach into growth-oriented adjacent markets, including cyber security, with a broader range of market-leading products and capabilities, strengthen its go-to-market resources to better support a larger, more diverse and

more global customer base, and increase NetScout's scale and elevate its strategic position within key accounts. For additional information regarding the Transaction, see Note 7 of our Notes to Consolidated Financial Statements.

Results Overview

NetScout’s financial results for the nine months ended December 31, 2015 include approximately five and one-half months of contribution from the Communications Business.

We continue to maintain strong liquidity. At December 31, 2015, we had cash, cash equivalents and marketable securities (current and non-current) of $376.2 million. This represents an increase of $111.3 million from March 31, 2015.

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 revenue, non-GAAP net income and non-GAAP net income per diluted share. Non-GAAP revenue eliminates the GAAP effects of acquisitions by adding back revenue related to deferred revenue revaluation, an adjustment for a delayed transfer entity, and the amortization of acquired intangible assets. Non-GAAP net income includes the foregoing adjustments and also removes expenses related to share-based compensation and certain expenses relating to acquisitions including: compensation for post-combination services, business development charges, and depreciation expenses, net of related income tax effects. Non-GAAP diluted net income per share also excludes these expenses as well as the related impact of all these adjustments on the provision for income taxes.

The Company described non-GAAP operating cash flows on its earnings call. The non-GAAP operating cash flow includes a reimbursement for retention awards (contingently returnable consideration), paid to NetScout, for former Danaher employees of $8.8 million.

These non-GAAP measures are not in accordance with GAAP, should not be considered an alternative for measures prepared in accordance with GAAP (revenue, net income and diluted net income per share), and may have limitations in that they do not reflect all our results of operations as determined in accordance with GAAP. These non-GAAP measures should only be used to evaluate our results of operations in conjunction with the corresponding GAAP measures. The presentation of non-GAAP information is not meant to be considered superior to, in isolation from, or as a substitute for results prepared in accordance with GAAP.

Management believes these non-GAAP financial measures enhance the reader's overall understanding of our current financial performance and its prospects for the future by providing a higher degree of transparency for certain financial measures and providing a level of disclosure that helps investors understand how we plan and measure our business. We believe that providing these non-GAAP measures affords investors a view of our operating results that may be more easily compared to our peer companies and also enables investors to consider our operating results on both a GAAP and non-GAAP basis during and following the integration period of our acquisitions. Presenting the GAAP measures on their own may not be indicative of our core operating results. Furthermore, management believes that the presentation of non-GAAP measures when shown in conjunction with the corresponding GAAP measures provide useful information to management and investors regarding present and future business trends relating to our financial condition and results of operations.

Critical Accounting Policies

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America consistently applied. The preparation of these consolidated financial statements requires us to make significant estimates and judgments that affect the amounts reported in our consolidated financial statements and the accompanying notes. These items are regularly monitored and analyzed by management for changes in facts and circumstances, and material changes in these estimates could occur in the future. Changes in estimates are recorded in the period in which they become known. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from our estimates.

While all of our accounting policies impact the consolidated financial statements, certain policies are viewed to be critical. Critical accounting policies are those that are both most important to the portrayal of our financial condition and results of operations and that require management's most subjective or complex judgments and estimates. We consider the following accounting policies to be critical in fully understanding and evaluating our financial results:


•	marketable securities;


•	revenue recognition;


•	valuation of goodwill, intangible assets and other acquisition accounting items; and


•	share-based compensation.

Table of Contents

Please refer to the critical accounting policies set forth in our Annual Report on Form 10-K for the fiscal year ended March 31, 2015, filed with the Securities and Exchange Commission (SEC) on May 20, 2015, for a description of all of our critical accounting policies.

The critical accounting policies included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2015 have not materially changed, other than the following:

The critical accounting policy entitled "Revenue Recognition" has been updated to reflect the combined policies of NetScout and the Communications Business.

Revenue Recognition

The Company exercises judgment and uses estimates in connection with determining the amounts of product and services revenues to be recognized in each accounting period.

The Company derives revenues primarily from the sale of network management tools and security solutions for carrier and enterprise customers, which include hardware, software and service offerings. The majority of the Company’s product sales consist of hardware products with embedded software that are essential to providing customers the intended functionality of the solutions. The Company also sells stand-alone software solutions to provide customers with enhanced functionality. In addition, the Company sells hardware bundled with a software license. Product revenue is recognized upon shipment, provided that evidence of an arrangement exists, title and risk of loss have passed to the customer, and in the case of software products, when the customer has the rights and ability to access the software, fees are fixed or determinable and collection of the related receivable is reasonably assured. If any significant obligations to the customer remain post-delivery, typically involving obligations relating to installation and acceptance by the customer, revenue recognition is deferred until such obligations have been fulfilled. Because many of the Company’s solutions are comprised of both hardware and more than incidental software components, the Company recognizes revenue in accordance with authoritative guidance on both hardware and software revenue recognition.

The Company’s service offerings include installation, integration, extended warranty and maintenance services, post-contract customer support (PCS), and other professional services including consulting and training. The Company generally provides software and/or hardware support as part of product sales. Revenue related to the initial bundled software and hardware support is recognized ratably over the support period. In addition, customers can elect to purchase extended support agreements for periods after the initial software/hardware warranty expiration. Support services generally include rights to unspecified upgrades (when and if available), telephone and internet-based support, updates and bug fixes. Consulting services are recognized upon delivery or completion of performance. Reimbursements of out-of-pocket expenditures incurred in connection with providing consulting services are included in services revenue, with the offsetting expense recorded in cost of service revenue. Training services include on-site and classroom training. Training revenues are recognized upon delivery of the training.

Generally, the Company’s contracts are accounted for individually. However, when contracts are closely interrelated and dependent on each other, it may be necessary to account for two or more contracts as one to reflect the substance of the group of contracts.

Multi-element arrangements are concurrent customer purchases of a combination of the Company’s product and service offerings that may be delivered at various points in time. For multi-element arrangements comprised only of hardware products and related services, the Company allocates the total arrangement consideration to the multiple elements based on each element’s selling price compared to the total relative selling price of all the elements. Each element’s selling price is based on management’s best estimate of selling price (BESP) paid by customers based on the element’s historical pricing when VSOE or third party evidence (TPE) does not exist. The Company has established BESP for product elements as the average or median selling price the element was recently sold for, whether sold alone or sold as part of a multiple element transaction. The Company also considers its overall pricing objectives and practices across different sales channels and geographies, and market conditions. The Company reviews sales of the product elements on a quarterly basis and updates, when appropriate; its BESP for such elements to ensure that it reflects recent pricing experience. The Company has established VSOE for a majority of its services related to undelivered elements based on historical stand-alone sales or by the renewal rate offered to the customer. If neither VSOE nor TPE of selling price exist for a deliverable, the Company uses its BESP for that deliverable.

For multi-element arrangements comprised only of software products and related services, the Company allocates a portion of the total arrangement consideration to the undelivered elements, primarily support agreements and training, using vendor-specific objective evidence of fair value for the undelivered elements. The remaining portion of the total arrangement consideration is allocated to the delivered software, referred to as the residual method. VSOE of fair value of the undelivered

Table of Contents

elements is based on the price customers pay when the element is sold separately. The Company reviews the separate sales of the undelivered elements on a regular basis and updates, when appropriate, its VSOE of fair value for such elements to ensure that it reflects recent pricing experience. If the Company cannot objectively determine the VSOE of the fair value of any undelivered software element, revenue is deferred until all elements are delivered and services have been performed, or until fair value can objectively be determined for any remaining undelivered elements. However, if the only undelivered element is maintenance and support, the entire arrangement fee is recognized over the service period.

For multi-element arrangements comprised of a combination of hardware and software elements, the total arrangement consideration is bifurcated between the hardware and hardware related deliverables and the software and software related deliverables based on the relative selling prices of all deliverables as a group. Then, arrangement consideration for the hardware and hardware-related services is recognized upon delivery or as the related services are provided outlined above and revenue for the software and software-related services is allocated following the residual method and recognized based upon delivery or as the related services are provided.

The Company’s products are distributed through its direct sales force and indirect distribution channels through alliances with resellers. Revenue arrangements with resellers are recognized on a sell-in basis; that is, when the Company delivers the product to the reseller. The Company records consideration given to a reseller as a reduction of revenue to the extent the Company has recorded revenue from the reseller. With limited exceptions, the Company’s return policy does not allow product returns for a refund. Returns have been insignificant to date. The Company does not offer price protection to its resellers. In addition, the Company has a history of successfully collecting receivables from the resellers.

Three Months Ended December 31, 2015 and 2014

Revenue

Product revenue consists of sales of our hardware products and licensing of our software products. Service revenue consists of customer support agreements, consulting and training. During the three months ended December 31, 2015, one direct customer accounted for more than 10% of our total revenue, while no indirect channel partner accounted for more than 10% of our total revenue. During the three months ended December 31, 2014, no direct customer or indirect channel partner accounted for more than 10% of our total revenue.

Total revenue	$	307,679	100	%	$	122,833	100	%	$	184,846	150	%

Product. The 174%, or $132.7 million, increase in product revenue compared to the same period last year was primarily due to $115.5 million in additional revenue resulting from the acquisition of the Communications Business and a $17.1 million increase in revenue from our legacy service provider sector in the United States.

Going forward, we expect that the revenue mix in future quarters will likely be oriented toward service provider customers since the revenue from Tektronix Communications has historically been from the service provider sector. However, the timing and magnitude of certain projects will impact the quarterly revenue mix in any given quarter.

Service. The 112%, or $52.2 million, increase in service revenue compared to the same period last year was primarily related to $47.2 million in incremental service revenue associated with the acquisition of the Communications Business, as well as a $4.5 million increase in revenue from new maintenance contracts in our legacy NetScout business and renewals from a growing support base. We expect continued service revenue growth to be generated by product revenue growth which increases our installed base and therefore our related maintenance contracts.

Total revenue	$	307,679	100	%	$	122,833	100	%	$	184,846	150	%

United States revenues increased 133%, or $118.0 million, compared to the same period last year, primarily due to a $91.3 million contribution from entities acquired as part of the Transaction as well as an increase within the legacy NetScout service provider sector in this region. The 197%, or $66.9 million, increase in international revenue compared to the same period last year is primarily due to a $71.5 million contribution from entities acquired as part of the Transaction, partially offset by a decrease across the general enterprise sector within the legacy NetScout business. We expect revenue from sales to customers outside the United States to continue to account for a significant portion of our total revenue in the future. In accordance with United States export control regulations we do not sell to, or do business with, countries subject to economic sanctions and export controls.

We expect that the combined legacy NetScout business and Communications Business will have a more balanced geography mix with approximately one third of our revenue coming from outside of North America.

Cost of Revenue and Gross Profit

Cost of product revenue consists primarily of material components, manufacturing personnel expenses, manuals, packaging materials, overhead and amortization of capitalized software, acquired software and core technology. Cost of service revenue consists primarily of personnel, material, overhead and support costs.

Table of Contents

ended December 31, 2014. A majority of the increase in cost of product revenue was due $59.5 million in incremental costs related to our acquisition of the Communications Business. The product gross profit percentage decreased by thirteen percentage points to 63% during the three months ended December 31, 2015 as compared to the three months ended December 31, 2014. The 127%, or $73.8 million, increase in product gross profit corresponds with the 174%, or $132.7 million, increase in product revenue, offset by the 321%, or $58.8 million, increase in cost of product revenue. Average headcount in manufacturing was 92 and 33 for the three months ended December 31, 2015 and 2014, respectively.

Service. There was a $20.3 million increase in cost of service revenue during the three months ended December 31, 2015 when compared to the three months ended December 31, 2014. This was primarily due to the $18.2 million increase in service cost related to the incremental revenue associated with the acquisition of the Communications Business. The service gross profit percentage decreased by ten percentage points to 71% for the three months ended December 31, 2015 as compared to the three months ended December 31, 2014. The 85%, or $31.9 million, increase in service gross profit corresponds with the 112%, or $52.2 million, increase in service revenue. Average service headcount was 598 and 168 for the three months ended December 31, 2015 and 2014, respectively.

Gross profit. Our gross profit increased 110%, or $105.7 million during the three months ended December 31, 2015 when compared to the three months ended December 31, 2014. This increase is attributable to our increase in revenue of 150%, or $184.8 million, partially offset by a 293%, or $79.1 million, increase in cost of revenue. The gross profit percentage decreased twelve percentage points to 66% for the three months ended December 31, 2015 as compared to the three months ended December 31, 2014.

Research and development. Research and development expenses consist primarily of personnel expenses, fees for outside consultants, overhead and related expenses associated with the development of new products and the enhancement of existing products.

The 245%, or $46.3 million, increase in research and development expenses is due to a $45.0 million increase in incremental costs from the acquisition of the Communications Business. These increases were offset by a $665 thousand decrease in compensation related items in the legacy NetScout business. Average headcount in research and development was 1,216 and 363 for the three months ended December 31, 2015 and 2014, respectively.

Sales and marketing. Sales and marketing expenses consist primarily of personnel expenses and commissions, overhead and other expenses associated with selling activities and marketing programs such as trade shows, seminars, advertising, and new product launch activities.

The 162%, or $56.6 million, increase in total sales and marketing expenses was due to a $53.5 million increase in incremental costs related to the acquisition of the Communications Business and a $988 thousand increase in compensation related expenses in the legacy NetScout business. Average headcount in sales and marketing was 941 and 376 for the three months ended December 31, 2015 and 2014, respectively.

General and administrative. General and administrative expenses consist primarily of personnel expenses for executive, financial, legal and human resource employees, overhead and other corporate expenditures.

The 131%, or $17.6 million, increase in general and administrative expenses was primarily due to a $16.0 million increase in incremental costs related to the acquisition of the Communications Business. Average headcount in general and administrative was 263 and 126 for the three months ended December 31, 2015 and 2014, respectively.

Table of Contents

Amortization of acquired intangible assets. Amortization of acquired intangible assets consists primarily of amortization of customer relationships, trademark and tradenames, and leasehold interest related to the acquisitions of the Communications Business, ONPATH Technologies, Inc. (ONPATH), Accanto, Simena, LLC (Simena), Fox Replay BV (Replay), Psytechnics, Ltd (Psytechnics) and Network General.

The 1,270%, or $10.4 million, increase in amortization of acquired intangibles assets was due to a $9.9 million increase in amortization associated with the acquisition of the Communications Business, as well as $568 thousand increase in the legacy NetScout business related to acceleration of the amortization of certain intangibles.

Interest and Other Expense, Net. Interest and other expense, net includes interest earned on our cash, cash equivalents and marketable securities, interest expense and other non-operating gains or losses.

The 467%, or $2.4 million, increase in interest and other expense was due to a $1.9 million increase in interest expense due to amounts drawn down on the credit facility entered into on July 14, 2015. In addition, there was a $626 thousand increase in foreign currency expense. These were partially offset by a $94 thousand increase in interest income received on investments.

Income Tax Expense. Our effective income tax rates were 3,670.3% and 35.7% for the three months ended December 31, 2015 and 2014, respectively. Generally, the effective tax rate differs from 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 December 31, 2015 is higher than the comparable prior year period primarily related to a decrease in profit before taxes due to Transaction related expenses recorded in the quarter, an increase in research and development credits attributable to acquired companies and a change in the jurisdictional mix of earnings.

Product. The 120%, or $238.9 million, increase in product revenue compared to the same period last year was primarily due to the $246.5 million additional revenue as a result of the acquisition of the Communications Business. This increase was partially offset by a $6.9 million decrease in revenue from our legacy general enterprise sector and a $776 thousand decrease in revenue from our legacy service provider sector.

Service. The 71%, or $96.4 million, increase in service revenue compared to the same period last year was primarily due to an $85.0 million increase from the expansion of our customer base due to the acquisition of the Communications Business and a $10.9 million increase in revenue from maintenance contracts in our legacy NetScout business due to increased new maintenance contracts and renewals from a growing support base.

United States revenues increased 89%, or $226.1 million, primarily due to a $211.7 million increase from entities acquired as part of the Transaction, as well as an increase within the legacy NetScout general enterprise sector in this region. The 136%, or $109.2 million, increase in international revenue is primarily due to a $119.8 million increase from entities acquired as part of the Transaction, partially offset by a decrease across the legacy general enterprise sector.

Product. The 267%, or $120.1 million, increase in cost of product revenue compared to the same period last year was mainly a result of the 120%, or $238.9 million increase in product revenue. A majority of the increase in cost of product revenue was primarily due to a $122.6 million increase related to the incremental costs related to our acquisition of the

Communications Business, as well as a $1.2 million increase in amortization of intangibles primarily due to the acceleration of intangibles in the legacy NetScout business. These increases were offset by a $2.5 million decrease in cost of goods sold for the legacy NetScout business as well as a $1.4 million decrease in obsolescence charges. The product gross profit percentage decreased by fifteen percentage points to 62% during the nine months ended December 31, 2015. Average headcount in manufacturing was 67 and 32 for the nine months ended December 31, 2015 and 2014, respectively.

Service. The 139%, or $36.4 million, increase in cost of service revenue compared to the same period last year was primarily due to a $34.1 million increase in incremental costs related to the acquisition of the Communications Business, as well as a $1.0 million increase in compensation related expenses in the NetScout Legacy business. The service gross profit percentage decreased by eight percentage points to 73% for the nine months ended December 31, 2015 when compared to the nine months ended December 31, 2014. The 55%, or $60.0 million, increase in service gross profit corresponds with the 71%, or $96.4 million, increase in service revenue, partially offset by the 139%, or $36.4 million, increase in cost of services. Average service headcount was 424 and 164 for the nine months ended December 31, 2015 and 2014, respectively.

Gross profit. Our gross profit increased 68%, or $178.8 million compared to the same period last year. This increase is attributable to our increase in revenue of 100% or $335.2 million, partially offset by a 220%, or $156.4 million, increase in cost of revenue. The gross profit percentage decreased by thirteen percentage points to 66% for the nine months ended December 31, 2015 when compared to the nine months ended December 31, 2014.

Research and development. The 162%, or $92.2 million, increase in research and development expenses compared to the same period last year was due to a $92.6 million increase in incremental costs related to the acquisition of the Communications Business, offset by a $710 thousand decrease in consulting expenses in the legacy NetScout business. Average headcount in research and development was 876 and 358 for the nine months ended December 31, 2015 and 2014, respectively.

Sales and marketing. The 100%, or $104.3 million, increase in total sales and marketing expenses compared to the same period last year was due to a $98.7 million increase in incremental costs related to the acquisition of the Communications Business, a $2.2 million increase in expenses related to the NetScout user conference and sales kickoff event due primarily to higher attendance and related rebranding activity, a $2.0 million increase in advertising expenses, and a $1.2 million increase in integration expenses in connection with the Transaction. Average headcount in sales and marketing was 700 and 373 for the nine months ended December 31, 2015 and 2014, respectively.

General and administrative. The 148%, or $49.3 million, increase in general and administrative expenses compared to the same period last year was due to a $28.7 million increase in incremental costs related to the acquisition of the Communication Business, a $14.9 million increase in integration expenses in connection with the Transaction and a $1.3 million increase in legal expenses. Average headcount in general and administrative was 198 and 121 for the nine months ended December 31, 2015 and 2014, respectively.

Amortization of acquired intangible assets. Amortization of acquired intangible assets consists primarily of amortization of customer relationships, trademark and tradenames, and leasehold interest related to the acquisitions of the Communications Business, ONPATH, Accanto, Simena, Replay, Psytechnics and Network General.

The 763%, or $19.4 million, increase in amortization of acquired intangibles assets were primarily due to $18.1 million in amortization related to the acquisition of the Communications Business, as well as $1.3 million in the legacy NetScout business related to acceleration of the amortization of certain intangibles.

The 227%, or $2.7 million, increase in interest and other expense was due to a $3.5 million increase in interest expense due to amounts drawn down on the credit facility entered into on July 14, 2015. This increase was partially offset by a $693 thousand increase due to a foreign currency gain, as well as a $221 thousand increase in interest income received on investments.

Income Tax Expense (Benefit). Our effective income tax rates were 1.0% and 37.9% for the nine months ended December 31, 2015 and 2014, respectively. Generally, the effective tax rate differs from the statutory tax rates due to the impact of the domestic production activities deduction, research and development credits, the impact of state taxes and income generated in jurisdictions that have a different rate than the U.S. statutory rate. The effective tax rate is lower than the comparable year primarily due to the decrease in profit before taxes due to Transaction related expenses recorded in the first nine months of fiscal year 2016, an increase in research and development tax credits attributable to acquired companies and a change in the jurisdictional mix of earnings.

Off-Balance Sheet Arrangements

At December 31, 2015 and 2014, we did not have any off-balance sheet arrangements as defined in Regulation S-K, Item 303(a)(4)(ii).

Commitment and Contingencies

We account for claims and contingencies in accordance with authoritative guidance that requires us to record an estimated loss from a claim or loss contingency when information available prior to issuance of our consolidated financial statements indicates that it is probable that a liability has been incurred at the date of the consolidated financial statements and the amount of the loss can be reasonably estimated. If we determine that it is reasonably possible but not probable that an asset has been impaired or a liability has been incurred or if the amount of a probable loss cannot be reasonably estimated, then in accordance with the authoritative guidance, we disclose the amount or range of estimated loss if the amount or range of estimated loss is material. Accounting for claims and contingencies requires us to use our judgment. We consult with legal counsel on those issues related to litigation and seek input from other experts and advisors with respect to matters in the ordinary course of business. For additional information with respect to legal proceedings, refer to Part II, Item 1 “Legal Proceedings.”

We have one contingent liability related to the acquisition of Simena in November 2011 for future consideration to be paid to the former seller which had an initial fair value of $8.0 million at the time of acquisition. At December 31, 2015, the fair value of the future consideration was $4.6 million.

We have a contingent liability related to the acquisition of the Communications Business which represents the tax effected portion of the contingently returnable consideration. At December 31, 2015, the fair value of the future consideration to be paid to Danaher was $2.6 million.

Cash, cash equivalents and marketable securities

At December 31, 2015, cash, cash equivalents and marketable securities (current and non-current) totaled $376.2 million, up $111.3 million from $264.9 million at March 31, 2015 due primarily to cash flow from the proceeds from issuance of debt in the amount of $244.6 million, cash provided by operations of $56.6 million, cash acquired as part of the Transaction in the amount of $27.7 million, partially offset by $212.4 million used to repurchase shares of our common stock and $14.1 million of cash used for capital expenditures.

Substantially all of our cash, cash equivalents and marketable securities are located in the United States. At December 31, 2015, cash and short-term and long-term investments in the United States was $320.4 million, while cash held outside the United States was approximately $55.8 million.

Cash and cash equivalents were impacted by the following:

Net cash provided by operating activities

Cash provided by operating activities was $56.6 million during the nine months ended December 31, 2015, compared to $57.3 million of cash provided by operating activities during the nine months ended December 31, 2014. This $724 thousand decrease was due in part to an $83.2 million increase in depreciation and amortization and a $25.1 million increase from accrued compensation and other expenses. The increase from accrued compensation and other expenses was due largely to the timing of accruals and payments for compensation related items and legal and accounting related fees. In addition, there was a $14.4 million increase from accounts payable, an $8.5 million increase from share-based compensation expense, a $6.6 million increase in deal related compensation, a $4.8 million increase in deferred income taxes and a $3.8 million increase from inventories. These increases were offset by a $65.1 million decrease from net income, a $36.2 million decrease from prepaid expenses and other assets, a $32.3 million decrease from deferred revenue, a $5.8 million decrease from amounts owed from related parties, a $4.3 million decrease from amounts that are due to a related party as a result of the Transaction and a $3.6 million unfavorable impact from accounts receivable in the nine months ended December 31, 2015 as compared to the nine months ended December 31, 2014. Days sales outstanding of 71 days at December 31, 2015 compared to 61 days at March 31, 2015 and 62 days at December 31, 2014.

On April 22, 2014, our board of directors approved a stock repurchase program. This program authorized management to make additional repurchases of our outstanding common stock of up to $100 million. Through December 31, 2015, we had repurchased 824,452 shares totaling $34.3 million in the open market under this stock repurchase plan. The Company repurchased 67,752 shares for $2.8 million under this program during the three months ended June 30, 2015. At December 31, 2015, there were no shares of common stock that remained available to be purchased under the plan due to the approval of a new share repurchase program approved on May 19, 2015.

Table of Contents

On May 19, 2015, the Company’s board of directors approved a new share repurchase program, conditional upon the completion of the Company's acquisition of the Communications Business, which 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 Transaction and replaces the Company's existing open market stock repurchase program described above. Through December 31, 2015, the Company has repurchased 5,196,596 shares totaling $201.0 million in the open market under this stock repurchase plan. At December 31, 2015, 14,803,404 shares of common stock remained available to be purchased under the plan. The Company announced that it intends to repurchase approximately $100 million shares of its common stock during the fourth quarter of its 2016 fiscal year pursuant to this repurchase program through open market repurchases pursuant to rule 10b5-1 under the Exchange Act. Such repurchases, and any future repurchases, will reduce our cash balance.

In addition, during the nine months ended December 31, 2015 and 2014, we had withheld 235,816 and 243,063 shares from employees for tax withholding at a cost of $8.6 million and $10.6 million, respectively.

During the nine months ended December 31, 2015, we received net proceeds in the amount of $244.6 million from long-term debt in connection with the drawdown on the loan on our new credit facility. The proceeds will be used to support the combined company's post-acquisition working capital needs as well as to execute on our share repurchase program.

We generated $1.8 million and $4.3 million during the nine months ended December 31, 2015 and 2014, respectively, of excess tax benefits from share-based compensation awards.

Credit Facility

On July 14, 2015, we entered into the Credit Agreement. The Credit Agreement provides for a five-year $800,000,000 senior secured revolving credit facility, including a letter of credit sub-facility of up to $50,000,000. We may elect to use the new credit facility for working capital purpose or repurchase of common stock under our authorized 20 million share 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 our election, revolving loans under the Credit Agreement bear interest at either (a) a 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 LIBO rate plus 1%; or (b) such adjusted LIBO rate (for the interest period selected by us), in each case plus an applicable margin. For the initial period until we have delivered financial statements for the quarter ended March 31, 2016, the applicable margin will be 1.75% per annum for LIBOR loans and 0.75% per annum for Base Rate loans, and thereafter the applicable margin will vary depending on its leverage ratio, ranging from 1.00% per annum for Base Rate loans and 2.00% per annum for LIBOR loans if our consolidated leverage ratio is greater than 2.50 to 1.00, down to 0.25% per annum for Base Rate loans and 1.25% per annum for LIBOR loans if our consolidated leverage ratio is equal to or less than 1.00 to 1.00.

Our 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.

Commitment fees will accrue on the daily unused amount of the credit facility. For the initial period until we have delivered financial statements for the quarter ended March 31, 2016, the commitment fee will be 0.20% per annum, and thereafter the commitment fee will vary depending on our consolidated leverage ratio, ranging from 0.35% per annum if our consolidated leverage ratio is greater than 2.50 to 1.00, down to 0.20% per annum if our 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, we will pay a fronting fee to each issuing bank in amounts to be agreed to between NetScout and the applicable issuing bank.

Interest on 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. NetScout may also prepay loans under the Credit Agreement at any time, without penalty, subject to certain notice requirements.

Table of Contents

The loans and other obligations under the credit facility are (a) guaranteed by each of NetScout’s wholly-owned material domestic restricted subsidiaries, subject to certain exceptions, and (b) are secured by substantially all of the assets of NetScout and the subsidiary guarantors, including a pledge of all the capital stock of material subsidiaries held directly by the Borrower 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 our assets and our restricted subsidiaries, subject to certain exceptions as described in the Credit Agreement.

The Credit Agreement contains certain covenants applicable to us and our 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, we are required to maintain certain consolidated leverage and interest coverage ratios. These covenants and limitations are more fully described in the Credit Agreement.

In connection with our new revolving credit facility described above, effective as of the Closing Date, we terminated our 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.

During the second fiscal quarter of 2016, subsequent to completion of the Transaction, we drew down $250 million to support general working capital requirements as well as to help finance the repurchase of our common stock under our 20 million share common stock repurchase plan approved in May 2015.

Expectations for Fiscal Year 2016

We believe that our cash balances, available debt, short-term marketable securities classified as available-for-sale and future cash flows generated by operations will be sufficient to meet our anticipated cash needs for working capital and capital expenditures for at least the next 12 months. In addition, we expect that cash provided by operating activities will continue to increase due to an expected increase in cash collections related to anticipated higher revenues, partially offset by an anticipated increase in operating expenses that require cash outlays such as salaries and commissions.

Additionally, a portion of our cash may be used to acquire or invest in complementary businesses or products or to obtain the right to use complementary technologies. From time to time, in the ordinary course of business, we evaluate potential acquisitions of such businesses, products or technologies. If our existing sources of liquidity are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity or debt securities. The sale of additional equity or debt securities could result in additional dilution to our stockholders.

NetScout's Liquidity and Capital Resources After the Acquisition of the Communications Business

Due to the ongoing nature of the integration planning, there is no estimate of costs associated with achieving any of the projected synergies or the consolidation of any operations and systems as well as professional fees associated with these activities. Additionally, as part of the Transaction, NetScout and Newco entered into a Transition Services Agreement with Danaher on July 14, 2015 (Transition Services Agreement), under which Danaher will provide the Communications Business specified support services and other assistance for a limited time following the closing of the Transaction.

We anticipate that our primary sources of liquidity for working capital and operating activities will be cash provided by operations, as well as the new Credit Agreement. We expect these sources of liquidity will be sufficient to fund working capital and capital expenditure requirements, including the significant one-time costs relating to the Transactions.

Recently Issued Accounting Pronouncements

In November 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2015-17, "Balance Sheet Classification of Deferred Taxes", (ASU 2015-17), which eliminates the current requirement to present deferred tax liabilities and assets as current and noncurrent. in a classified balance sheet. Instead, entities will be required to classify all deferred tax assets and liabilities as noncurrent. We adopted this standard prospectively in the third quarter of fiscal year 2016 as early adoption was permitted and prior periods were not retrospectively adjusted.

In September 2015, the FASB issued Accounting Standards Update No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, (ASU 2015-16), which eliminates the requirement to restate prior financial statements for measurement period adjustments. The new guidance requires that the cumulative impact of a measurement period adjustment be recognized in the reporting period in which the adjustment is identified. We adopted this standard in the second quarter of fiscal year 2016.

In August 2015, the FASB issued ASU 2015-15,Interest-Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-Of-Credit Arrangements and Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (ASU 2015-15). The guidance in the previously issued ASU 2015-03, "Interest-Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs" does not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. Given the absence of authoritative guidance within ASU 2015-03 for debt issuance costs related to line-of-credit arrangements, the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. We adopted this standard in the second quarter of fiscal year 2016.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09), to supersede nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. ASU 2014-09 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. This ASU will be effective for us in our first quarter of fiscal year 2019. Early adoption is not permitted. This ASU allows for either full retrospective or modified retrospective adoption. We are currently evaluating the impact of our pending adoption of ASU 2014-09 on our consolidated financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk. We hold our cash, cash equivalents and investments for working capital purposes. Some of the securities we invest in are subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. To minimize this risk, we maintain our portfolio of cash, cash equivalents and investments in a variety of securities, including money market funds and government debt securities. The risk associated with fluctuating interest rates is limited to our investment portfolio. Due to the short-term nature of these instruments, we believe that we do not have any material exposure to changes in the fair value of our investment portfolio as a result of changes in interest rates. Declines in interest rates, however, would reduce future interest income. The effect of a hypothetical 10% increase or decrease in overall interest rates would not have had a material impact on our operating results or the total fair value of the portfolio.

We are exposed to market risks related to fluctuations in interest rates related to our credit facility. As of December 31, 2015, we owed $250 million on this loan with an interest rate of 2.18%. A sensitivity analysis was performed on the outstanding portion of our debt obligation as of December 31, 2015. Should the current weighted average interest rate increase or decrease by 10%, the resulting annual increase or decrease to interest expense would be approximately $545 thousand as of December 31, 2015.

Foreign Currency Exchange Risk. As a result of our foreign operations, we face exposure to movements in foreign currency exchange rates, primarily the Euro, British Pound, Canadian Dollar and Indian Rupee. The current exposures arise primarily from expenses denominated in foreign currencies. We currently engage in foreign currency hedging activities in order to limit these exposures. We do not use derivative financial instruments for speculative trading purposes.

As of December 31, 2015, we had foreign currency forward contracts with notional amounts totaling $11.6 million. The valuation of outstanding foreign currency forward contracts at December 31, 2015 resulted in an asset balance of $8 thousand, reflecting favorable rates in comparison to current market rates and a liability balance of $467 thousand, reflecting unfavorable contract rates in comparison to current market rates at this date. As of March 31, 2015, we had foreign currency forward contracts with notional amounts totaling $20.2 million. The valuation of outstanding foreign currency forward contracts at March 31, 2015 resulted in a liability balance of $1.7 million, reflecting unfavorable contract rates in comparison to current market rates at this date and an asset balance of $15 thousand reflecting favorable rates in comparison to current market rates. The effect of a hypothetical 10% change in foreign currency exchange rates applicable to our business would not have a material impact on our historical consolidated financial statements. As our international operations grow, we will continue to reassess our approach to manage our risk relating to fluctuations in currency rates.

Item 4. Controls and Procedures

At December 31, 2015, NetScout, under the supervision and with the participation of our management, including the Company's principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) promulgated under the Securities Exchange Act of 1934, as amended (Exchange Act). Based upon that evaluation, our principal executive officer and principal financial officer concluded that, at December 31, 2015, our disclosure controls and procedures were effective in ensuring that material information relating to NetScout, including its consolidated subsidiaries, required to be disclosed by NetScout in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, including ensuring that such material information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

On July 14, 2015, we completed our acquisition of the Communications Business. We have extended our oversight and monitoring processes that support our internal control over financial reporting to include these operations. We are continuing to integrate these acquired operations into our overall internal control over financial reporting process. There has been no other change in our internal control over financial reporting during the quarter ended December 31, 2015 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

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 significant adverse effect on our financial condition, results of operations or cash flows.

Item 1A. Risk Factors

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for our fiscal year ended March 31, 2015, and the risk factors listed below. The risks discussed in our Annual Report on Form 10-K and below could materially affect our business, financial condition and future results. The risks described in our Annual Report on Form 10-K and below are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition or operating results.

Risks related to the Combined Company’s Business Following the Acquisition of Danaher’s Communications Business

The Transaction may not be successful or achieve its anticipated benefits.

We may not be able to successfully realize anticipated growth opportunities or integrate our business and operations with the Communications Business’ business and operations. Following the Transaction, we have significantly more revenue, expenses, assets and employees than we did prior to the Transaction. We may not successfully or cost-effectively integrate the Communications Business’ business and operations into our existing business and operations. Even if the combined company is able to integrate the combined businesses and operations successfully, this integration may not result in the realization of the full benefits of the growth and other opportunities that we currently expect from the Transaction within the anticipated time frame, or at all.

We will continue to incur significant expenses and management will devote significant time in connection with the integration of the Communications Business.

We will continue to incur significant expenses in connection with the integration of the Communications Business, including integrating products and technology, personnel, information technology systems, accounting systems, suppliers, and channel partners of each business and implementing consistent standards, policies, and procedures, and may possibly be subject to material write downs in assets and charges to earnings. Further, our management team will devote significant time and attention to the integration efforts which may distract us from operating our ongoing business operations.

Risks related to the Company and its Operations

Foreign currency exchange rates may adversely affect our financial statements.

Sales and purchases in currencies other than the U.S. dollar expose us to fluctuations in foreign currencies relative to the U.S. dollar and may adversely affect our financial statements. Increased strength of the U.S. dollar (such as the strengthening that has taken place in recent periods) increases the effective price of our products sold in U.S. dollars into other countries, which may require us to lower our prices or adversely affect sales to the extent we do not increase local currency prices. Decreased strength of the U.S. dollar could adversely affect the cost of materials, products and services we purchase overseas. Sales and expenses of our non-U.S. businesses are also translated into U.S. dollars for reporting purposes and the strengthening or weakening of the U.S. dollar could result in unfavorable translation effects. In addition, certain of our businesses may invoice customers in a currency other than the business' functional currency, and movements in the invoiced currency relative to the functional currency could also result in unfavorable translation effects. The Company also faces exchange rate risk from its investments in subsidiaries owned and operated in foreign countries.

Our indebtedness may limit our operations and our use of our cash flow, and any failure to comply with the covenants that apply to our indebtedness could adversely affect our liquidity and financial condition.

On July 14, 2015, we entered into a certain credit facility with a syndicate of lenders pursuant to a Credit Agreement (Credit Agreement). 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. We may elect to use the new credit facility for working capital purpose or repurchase common stock under our previously announced 20 million share 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. As of the date of this report, we had approximately $250 million in outstanding indebtedness under the Credit Agreement. Our debt

level can have negative consequences, including exposing us to interest rate risk. We may incur significantly more debt in the future, and there can be no assurance that our cost of funding will not substantially increase. Our current revolving credit facility also imposes certain restrictions on us; for more information please refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations”. 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, which would adversely affect our liquidity and financial condition. If we take on additional indebtedness, the risks described above could increase.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Sales of Unregistered Securities

None.
