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 the Company's audited financial statements, but does not include all disclosures required by GAAP. The results reported in these unaudited interim consolidated financial statements are not necessarily indicative of results that may be expected for the entire year. All significant intercompany accounts and transactions are eliminated in consolidation.

These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018 filed with the Securities and Exchange Commission on May 21, 2018.

Certain amounts for the three months ended June 30, 2017 have been reclassified to conform to the current period presentation. These reclassifications had no effect on the reported results of operations.

Recent Accounting Pronouncements

In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2018-02, Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income (ASU 2018-02). ASU 2018-02 amends ASC 220, Income Statement - Reporting Comprehensive Income, to allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (Tax Legislation). In addition, under the ASU 2018-02, we may be required to provide certain disclosures regarding stranded tax effects. ASU 2018-02 is effective for years beginning after December 15, 2018, and interim periods within those fiscal years. ASU 2018-02 is effective for NetScout beginning April 1, 2019. Early adoption is permitted. We do not believe the adoption of ASU 2018-02 will have a material impact on our consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815), Targeted Improvements to Accounting for Hedging Activities (ASU 2017-12). ASU 2017-12 provides guidance to better align an entity's risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The amendments expand and refine hedge accounting for both non-financial and financial risk components and align the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This standard is effective for financial statements issued for fiscal years beginning after December 15, 2018, with early adoption permitted. ASU 2017-12 is effective for the Company beginning April 1, 2019. The Company is currently assessing the potential impact of the adoption of ASU 2017-12 on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) Section A - Leases: Amendments to the FASB Accounting Standards Codification (ASU 2016-02), its new standard on accounting for leases. This update requires the recognition of leased assets and lease obligations by lessees for those leases currently classified as operating leases under existing lease guidance. Short term leases with a term of 12 months or less are not required to be recognized. The update also requires disclosure of key information about leasing arrangements to increase transparency and comparability among organizations. ASU 2016-02 is effective for annual reporting periods beginning after December 31, 2018 and interim periods within those fiscal years, and early adoption is permitted. ASU 2016-02 is effective for the company beginning April 1, 2019. The Company is currently assessing the potential impact of the adoption of ASU 2016-02 on its consolidated financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers: Topic 606 (ASU 2014-09). ASU 2014-09 supersedes the revenue recognition requirements in Topic 605, Revenue Recognition, and requires entities to recognize revenue when control of the promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. The Company adopted ASU 2014-09 as of April 1, 2018 using the modified retrospective transition method. Please refer to Note 2, "Revenue Recognition" for further details.

NOTE 2 – REVENUE RECOGNITION

Revenue from Contracts with Customers

In May 2014, the FASB issued Topic 606, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Topic 606 replaced most existing revenue recognition guidance under GAAP. The new standard introduces a five-step process to be followed in determining the amount and timing of revenue recognition. It also provides guidance on accounting for costs incurred to obtain or fulfill contracts with customers and establishes disclosure requirements which are more extensive than those required under prior GAAP.

Topic 606 became effective for the Company on April 1, 2018. The Company elected to use the modified retrospective transition approach. Therefore, the comparative financial information has not been restated and continues to be reported under the accounting standards in effect for those periods.

Revenue Recognition Policy

The Company exercises judgment and use 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 service provider and enterprise customers, which include hardware, software and service offerings. The majority of its 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.

The Company accounts for revenue once a legally enforceable contract with a customer has been approved by the parties and the related promises to transfer products or services have been identified. A contract is defined by the Company as an arrangement with commercial substance identifying payment terms, each party’s rights and obligations regarding the products or services to be transferred and collection is probable. Customer contracts may include promises to transfer multiple products and services to a customer. Determining whether the products and services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation may require significant judgment. Revenue is recognized when control of the products or services are transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for products and services.

Product revenue is recognized upon shipment, provided a legally enforceable contract exists, control has passed to the customer, and in the case of software products, when the customer has the rights and ability to access the software, and collection of the related receivable is probable. 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. The Company's service offerings include installation, integration, extended warranty and maintenance services, post-contract customer support, stand-ready software-as-a-service (SAAS) 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, bug fixes and hardware repair and replacement. Consulting services are recognized upon delivery or completion of performance depending on the terms of the underlying contract. SAAS services are recognized ratably over the contract term beginning on the commencement of services. 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.

Bundled arrangements are concurrent customer purchases of a combination of our product and service offerings that may be delivered at various points in time. The Company allocates the transaction price among the performance obligations in an amount that depicts the relative standalone selling prices (SSP) of each obligation. Judgment is required to determine the SSP for each distinct performance obligation. The Company uses a range of amounts to estimate SSP when it sells each of the products and services separately based on the element’s historical pricing. The Company also considers its overall pricing objectives and practices across different sales channels and geographies, and market conditions. Generally, the Company has established SSP for a majority of its service elements based on historical standalone sales. In certain instances, the Company has established SSP for services based upon an estimate of profitability and the underlying cost to fulfill those services. Further,

Table of Contents

for certain service engagements, the Company considers quoted prices as part of multi element arrangements of those engagements as a basis for establishing SSP. SSP has been established 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 reviews sales of the product elements on a quarterly basis and updates, when appropriate, its SSP for such elements to ensure that it reflects recent pricing experience. The Company's products are distributed through its direct sales force and indirect distribution channels through alliances with resellers and distributors. Revenue arrangements with resellers and distributors are recognized on a sell-in basis; that is, product is delivered to the reseller or distributor. The Company records consideration given to a reseller or distributor as a reduction of revenue to the extent they have recorded revenue from the reseller or distributor. With limited exceptions, its return policy does not allow product returns for a refund. Returns have been insignificant to date. In addition, the Company has a history of successfully collecting receivables from its resellers and distributors.

Financial Statement Impact of Adoption

The cumulative impact of applying Topic 606 to all contracts with outstanding performance obligations as of April 1, 2018 was recorded as an adjustment to retained earnings as of the adoption date. As a result of applying the modified retrospective approach to adopt the new standard, the following adjustments were made to accounts on the consolidated balance sheet at April 1, 2018 (in thousands):



	Balance at March 31, 2018		Adjustments from Adopting Topic 606			Balance at April 1, 2018
ASSETS:
Accounts receivable and unbilled costs	$	213,438	$	1,195		$	214,633
Prepaid expenses and other current assets	33,502		4,626			38,128
Other assets	12,866		4,748			17,614
LIABILITIES:
Deferred revenue and customer deposits	301,925		(30,227		)	271,698
Deferred tax liability	151,563		7,899			159,462
Long-term deferred revenue and customer deposits	91,409		(1,252		)	90,157
STOCKHOLDERS' EQUITY:
Retained earnings	396,493		34,149			430,642

In connection with the adoption of the new revenue recognition accounting standard, the Company increased its retained earnings by $34.1 million, due to uncompleted contracts at April 1, 2018, for which $34.9 million of revenue will not be recognized in future periods under the new standard. The Company capitalized $7.1 million of incremental sales commission costs on the adoption date directly related to obtaining customer contracts and is amortizing these costs as it satisfies the underlying performance obligations, which for certain contracts can include anticipated renewal periods. The acceleration of revenue that was deferred under prior guidance as of April 1, 2018 was primarily attributable to no longer requiring the separation of promised goods or services, such as software licenses, technical support, specified and unspecified upgrade rights on the basis of vendor specific objective evidence, and the impact of allocating the transaction price to the software performance obligations in the contract on a relative basis using standalone selling price rather than allocating under the residual method, which allocates the entire arrangement discount to the delivered performance obligations. In addition, revenue from perpetual licenses and associated hardware with extended payment terms and term licenses are now recognized when control is transferred to the customer, the point in time when the customer can use and benefit from the license. Previously the Company recognized revenue over the term of the agreements as payments became due or earlier if prepaid.

The net change in deferred income taxes of $7.9 million is primarily due to the deferred tax effects resulting from the adjustment to retained earnings for the cumulative effect of applying Topic 606 to active contracts as of the adoption date.

The adoption of Topic 606 had no impact to net cash provided by or used in operating, investing and financing activities on the Company’s consolidated statements of cash flows during the three months ended June 30, 2018.

Performance Obligations

Customer contracts may include promises to transfer multiple products and services to a customer. Determining whether the products and services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation may require significant judgment. The transaction price is allocated among performance obligations in bundled contracts in an amount that depicts the relative standalone selling prices of each obligation.

For contracts involving distinct hardware and software licenses, the performance obligations are satisfied at a point in time when control is transferred to the customer. For standalone maintenance and post-contract support (PCS) the performance obligation is satisfied ratably over the contract term as a stand-ready obligation. For consulting and training services, the performance obligation may be satisfied over the contract term as a stand-ready obligation, satisfied over a period of time as those services are delivered, or satisfied at the completion of the service when control has transferred or the services have expired unused.

Payments for hardware, software licenses, one-year maintenance, PCS and consulting services, are typically due up front with payment terms of 30 to 90 days. However, the Company does have contracts which billings occur ratably over a period of years following the transfer of control for the contracted performance obligations. Payments on multi-year maintenance, PCS and consulting services are typically due in annual installments over the contract term. The Company did not have any material variable consideration such as obligations for returns, refunds or warranties at June 30, 2018.

At June 30, 2018, the Company had total deferred revenue of $328.7 million, which represents the aggregate total contract price allocated to undelivered performance obligations. The Company expects to recognize $248.2 million or 76% of this revenue during the next 12 months, and expects to recognize the remaining $80.5 million or 24% of this revenue thereafter.

Table of Contents

Because of NetScout's revenue recognition policies, there are circumstances for which the Company does not recognize revenue relating to sales transactions that have been billed, but the related account receivable has not been collected. While the receivable represents an enforceable obligation, for balance sheet presentation purposes, the Company has not recognized the deferred revenue or the related account receivable and no amounts appear in the consolidated balance sheets for such transactions. The aggregate amount of unrecognized accounts receivable and deferred revenue was $18.7 million and $20.0 million at June 30, 2018 and March 31, 2018, respectively.

NetScout expects that the amount of billed and unbilled deferred revenue will change from quarter to quarter for several reasons, including the specific timing, duration and size of large customer support and service agreements, varying billing cycles of such agreements, the specific timing of customer renewals, and foreign currency fluctuations. The Company did not have any significant financing components, or variable consideration or performance obligations satisfied in a prior period recognized during the three months ended June 30, 2018.

Contract Balances

The Company receives payments from customers based on a billing schedule as established by the Company’s contracts. Contract assets relate to performance obligations in advance of scheduled billings. Upon adoption, the Company recorded unbilled accounts receivable representing the right to consideration in exchange for goods or services that have been transferred to a customer conditional on the passage of time. The Company did not record any contract assets upon adoption. Deferred revenue relates to payments received in advance of performance under the contract. The following table provides information about contract assets and liabilities (in thousands):



	April 1, 2018		June 30, 2018		Increase/ (Decrease)
ASSETS:
Customer accounts receivable	$	205,299	$	155,613	$	(49,686	)

Costs to Obtain Contracts

The Company has determined the only significant incremental costs incurred to obtain contracts with clients within the scope of Topic 606 are sales commissions paid to its associates. Sales commissions are recorded as an asset and amortized to expense ratably over the remaining performance periods of the related contracts with remaining performance obligations. The Company applies the practical expedient in Topic 606 and expenses costs as incurred for sales commissions when the amortization period would have been one year or less.

At June 30, 2018, the consolidated balance sheet included $6.1 million in assets related to sales commissions to be expensed in future periods. A balance of $3.9 million was included in prepaid expenses and other current assets, and a balance of $2.2 million was included as other assets in the Company's consolidated balance sheet at June 30, 2018.

During the three months ended June 30, 2018, the Company recognized $0.6 million of amortization related to this sales commission asset, which is included in the sales and marketing expense line in our consolidated statements of operations.

NOTE 3 – CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS

Financial instruments that potentially subject the Company 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 June 30, 2018 and March 31, 2018, the Company had no direct customers or indirect channel partners which accounted for more than 10% of the accounts receivable balance.

During the three months ended June 30, 2018 and June 30, 2017, no direct customers or indirect channel partners accounted for more than 10% of the Company's total revenue.

As disclosed parenthetically within the Company's consolidated balance sheet, the Company has receivables from related parties included within prepaid expenses and other current assets that represent a concentration of credit risk of $1.7 million and $3.2 million at June 30, 2018 and March 31, 2018, respectively.

Historically, the Company has not experienced any significant failure of its customers' ability to meet their payment obligations nor does the Company anticipate material non-performance by its customers in the future; accordingly, the Company does not require collateral from its customers. However, if the Company's assumptions are incorrect, there could be an adverse impact on its allowance for doubtful accounts.

NOTE 4 – SHARE-BASED COMPENSATION

The following is a summary of share-based compensation expense including restricted stock units granted pursuant to the Company's 2007 Equity Incentive Plan, as amended, and employee stock purchases made under the Company's 2011 Employee Stock Purchase Plan (ESPP) based on estimated fair values within the applicable cost and expense lines identified below (in thousands):

The offering periods run from March 1st through August 31st and from September 1st through the last day of February each year.

NOTE 5 – CASH, CASH EQUIVALENTS, RESTRICTED CASH AND MARKETABLE SECURITIES

The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents and those investments with original maturities greater than three months to be marketable securities. Cash and cash equivalents consisted of money market instruments and cash maintained with various financial institutions at June 30, 2018 and March 31, 2018.

NOTE 6 – 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 June 30, 2018 and March 31, 2018 (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 calculated using market observable data for similar but not identical instruments, or a discounted cash flow model using the contractual interest rate as compared with the underlying interest yield curve. The Company classifies municipal obligations as level 2 because the fair values are determined using quoted prices from markets the Company considers to be inactive. Commercial paper is classified as Level 2 because the Company uses market information from similar but not identical instruments and discounted cash flow models based on interest rate yield curves to determine fair value. The Company's 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's Level 3 liabilities consist of contingent purchase consideration.

Table of Contents

The fair value of contingent purchase consideration related to the acquisition of Simena LLC (Simena) in November 2011 for future consideration to be paid to the seller is $5.0 million and $4.9 million at June 30, 2018 and March 31, 2018 respectively. The contingent purchase consideration is included as a contingent liability within accrued other in the Company's consolidated balance sheet at June 30, 2018 and March 31, 2018.

The Company's contingent purchase consideration also includes $523 thousand related to the acquisition of certain assets and liabilities of Efflux Systems, Inc. (Efflux) in the second quarter of fiscal year 2018. The contingent purchase consideration represents amounts deposited into an escrow account, which was established to cover damages NetScout may suffer related to any liabilities that NetScout did not agree to assume or as a result of the breach of representations and warranties of the seller as described in the merger agreement. The contingent purchase consideration is included as accrued other in the Company's consolidated balance sheet at June 30, 2018 and March 31, 2018.

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 three months ended June 30, 2018 (in thousands):



	Contingent Purchase Consideration
Balance at March 31, 2018	$	(5,464	)
Increase in fair value and accretion expense (included within research and development expense)	(38		)
Balance at June 30, 2018	$	(5,502	)

Deal-related compensation expense and accretion charges related to the contingent consideration for the three months ended June 30, 2018 was $38 thousand and was included as part of earnings.

NOTE 7 – 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):

NOTE 8 - ACQUISITIONS

Efflux

On July 12, 2017 (the Efflux Closing Date), the Company completed the acquisition of Efflux Systems, Inc. (Efflux) for $8.6 million. Efflux's technology detects, analyzes and correlates threat activity within enterprise networks. The Efflux technology and engineering talent have been integrated into Arbor Networks in order to support the ongoing enhancement of Arbor Spectrum for advanced threat detection.

Goodwill was recognized for the excess purchase price over the fair value of the net assets acquired. Goodwill of $6.1 million from the acquisition was included within the Security reporting unit. Goodwill and intangible assets recorded as part of the acquisition are not deductible for tax purposes.

NOTE 9 – GOODWILL AND INTANGIBLE ASSETS

Goodwill

The Company has two reporting units: (1) Service Assurance and (2) Security. The Company assesses goodwill for impairment at the reporting unit level at least annually, or on an interim basis if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value. The Company completed its annual impairment test on January 31, 2018. The Company performed an interim quantitative test as of June 30, 2018 related to the intangible asset impairment. The estimated fair value of both reporting units significantly exceeded their carrying value.

Table of Contents

At June 30, 2018, goodwill attributable to our Service Assurance and Security reporting units was $1.2 billion and $555.3 million, respectively. At March 31, 2018, goodwill attributable to our Service Assurance and Security reporting units was $1.2 billion and $555.9 million, respectively.

The change in the carrying amount of goodwill for the three months ended June 30, 2018 is due to the impact of foreign currency translation adjustments related to asset balances that are recorded in currencies other than the U.S. Dollar.

The changes in the carrying amount of goodwill for the three months ended June 30, 2018 are as follows (in thousands):



Balance at March 31, 2018	$	1,712,764
Foreign currency translation impact	5,735
Balance at June 30, 2018	$	1,718,499

Intangible Assets

The net carrying amounts of intangible assets were $756.4 million and $831.4 million at June 30, 2018 and March 31, 2018, 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.

During the three months ended June 30, 2018, the Company performed a quantitative analysis on certain intangible assets related to the handheld network tools product area, which is currently in the process of being divested. At June 30, 2018, the handheld network tools asset group did not qualify as held for sale. The fair value for the intangible assets related to the handheld network tools asset group was calculated considering a range of potential transaction prices which we consider to be a Level 3 measurement. The fair value of these intangible assets was determined to be less than the carrying value, and as a result, the Company recognized an impairment charge of $35.9 million in the three months ended June 30, 2018. The impairment charge was recorded within a separate operating expense line item in the Company's consolidated statements of operations during the three months ended June 30, 2018.

Intangible assets include the indefinite-lived trade name with a carrying value of $18.6 million and the following amortizable intangible assets at June 30, 2018 (in thousands):

NOTE 10 – DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

NetScout operates internationally and, in the normal course of business, is exposed to fluctuations in foreign currency exchange rates. The exposures result from costs that are denominated in currencies other than the U.S. Dollar, primarily the Euro, British Pound, Canadian Dollar, and Indian Rupee. The Company manages its foreign cash flow risk by hedging forecasted cash flows for operating expenses denominated in foreign currencies for up to twelve months, within specified guidelines through the use of forward contracts. The Company enters into foreign currency exchange contracts to hedge cash flow exposures from costs that are denominated in currencies other than the U.S. Dollar. These hedges are designated as cash flow hedges at inception.

All of the Company's derivative instruments are utilized for risk management purposes, and the Company does not use derivatives for speculative trading purposes. These contracts will mature over the next twelve months and are expected to impact earnings on or before maturity.

The notional amounts and fair values of derivative instruments in the consolidated balance sheets at June 30, 2018 and March 31, 2018 were as follows (in thousands):

NOTE 11 – LONG-TERM DEBT

On January 16, 2018, the Company amended and expanded its existing credit agreement (Amended Credit Agreement) with a syndicate of lenders 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; Fifth Third Bank, Santander Bank, N.A., SunTrust Bank, N.A. and U.S. Bank National Association, as co-documentation agents; and the lenders party thereto.

The Amended Credit Agreement provides for a five-year, $1.0 billion senior secured revolving credit facility, including a letter of credit sub-facility of up to $75.0 million. The Company may elect to use the new credit facility for general corporate purposes or to finance the repurchase of the Company's common stock under the Company's common stock repurchase plan.

Table of Contents

The commitments under the Amended Credit Agreement will expire on January 16, 2023, and any outstanding loans will be due on that date.

On February 1, 2018, the Company also announced that it entered into agreements with JPMorgan Chase Bank, National Association and Bank of America, N.A. (the Dealers) to repurchase an aggregate of $300 million of the Company's common stock via accelerated stock repurchase transactions (the ASR) under the Company's previously disclosed share repurchase program. On February 1, 2018, the Company borrowed an additional $300 million aggregate principal amount under its Amended Credit Agreement in order to finance the payment of the ASR to each of the Dealers. At June 30, 2018, $600 million was outstanding under the Amended Credit Agreement.

At the Company's election, revolving loans under the Amended Credit Agreement bear interest at either (a) an Alternate Base Rate per annum equal to the greatest of (1) JPMorgan's prime rate, (2) 0.50% in excess of the New York Federal Reserve Bank (NYFRB) rate, or (3) an adjusted one month LIBOR rate plus 1%; or (b) such adjusted LIBOR rate (for the interest period selected by the Company), in each case plus an applicable margin. For the period from the delivery of the Company's financial statements for the quarter ended March 31, 2018, until the Company has delivered financial statements for the quarter ended June 30, 2018, the applicable margin will be 1.50% per annum for LIBOR loans and 0.50% per annum for Alternate Base Rate loans, and thereafter the applicable margin will vary depending on the Company's leverage ratio, ranging from 1.00% per annum for Base Rate loans and 2.00% per annum for LIBOR loans if the Company's consolidated leverage ratio is greater than 3.50 to 1.00, down to 0.00% per annum for Alternate Base Rate loans and 1.00% per annum for LIBOR loans if the Company's consolidated leverage ratio is equal to or less than 1.50 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 adjusted EBITDA in the Amended Credit Agreement.

Commitment fees will accrue on the daily unused amount of the credit facility. For the period from the delivery of the Company's financial statements for the quarter ended March 31, 2018 until the Company has delivered financial statements for the quarter ended June 30, 2018, the commitment fee was 0.25% per annum, and thereafter the commitment fee will vary depending on the Company's consolidated leverage ratio, ranging from 0.30% per annum if the Company's consolidated leverage ratio is greater than 2.75 to 1.00, down to 0.15% per annum if the Company's consolidated leverage ratio is equal to or less than 1.50 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 Amended 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 Amended 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 Amended 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 Amended Credit Agreement.

The Amended 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 Amended Credit Agreement. At June 30, 2018, the Company was in compliance with all covenants.

Table of Contents

The Amended 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 Amended 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 Amended Credit Agreement and the other loan documents.

In connection with the Company's Amended Credit Agreement described above, the Company terminated its previous term loan 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 Company has capitalized debt issuance costs totaling $12.2 million at June 30, 2018, which are being amortized over the life of the revolving credit facility. The unamortized balance was $7.9 million as of June 30, 2018. The balance of $1.7 million was included as prepaid expenses and other current assets and a balance of $6.2 million was included as other assets in the Company's consolidated balance sheet.

NOTE 12 – RESTRUCTURING CHARGES

During the fourth quarter of fiscal year ended March 31, 2017, the Company restructured certain departments to better align functions subsequent to the acquisition of Danaher Corporation's Communications Business, which included certain assets, liabilities, technology and employees within Tektronix Communications, VSS Monitoring, Arbor Networks and certain portions of the Fluke Networks Enterprise business, which excluded Danaher's data communications cable installation business and its communication service provider business (the Comms Transaction), resulting in the termination of forty-one employees. As a result of the workforce reduction, during the fiscal year ended March 31, 2017, the Company recorded a restructuring charge totaling $1.9 million related to one-time termination benefits and $0.4 million in facility-related charges. The Company recorded an additional charge for one-time termination benefits of $0.9 million during the fiscal year ended March 31, 2018, of which $0.2 million was recorded during the quarter ended June 30, 2017. The one-time termination benefits and facilities-related costs related to this plan were paid in full during the fiscal year ended March 31, 2018.

During the third quarter of fiscal year ended March 31, 2018, the Company restructured certain departments to better align functions resulting in the termination of sixty-one employees. As a result of the workforce reduction, during the twelve months ended March 31, 2018, the Company recorded a restructuring charge totaling $5.1 million related to one-time termination benefits for the employees that were notified during the period. During the three months ended June 30, 2018, the Company recorded restructuring expenses of $1.1 million for one-time termination benefits and facilities-related costs. Additional one-time termination benefit charges and facility-related costs of approximately $0.1 million are anticipated to be recorded in the next three months. The one-time termination benefits will be paid in full during the fiscal year ending March 31, 2019.

The following table provides a summary of the activity related to the restructuring plans and the related restructuring liability (in thousands):



	Q3 FY 2018 Plan
	Employee-Related			Facility-Related			Total
Balance at March 31, 2018	$	3,696		$	—		$	3,696
Restructuring charges to operations	1,017			643			1,660

Other adjustments	(648		)	(185		)	(833		)
Balance at June 30, 2018	$	1,763		$	—		$	1,763

The accrual for employee-related severance is included as accrued compensation in the Company's consolidated balance sheets at June 30, 2018 and March 31, 2018 as the balance is expected to be paid in full within the next twelve months.

NOTE 13 – COMMITMENTS AND CONTINGENCIES

Acquisition related – The Company has a contingent liability related to the acquisition of Simena in November 2011 for future consideration to be paid to the seller which had an initial fair value of $8.0 million at the time of acquisition. At June 30, 2018 and March 31, 2018, the present value of the future consideration was $5.0 million and $4.9 million, respectively.

The Company had a contingent liability at June 30, 2018 for $523 thousand related to the acquisition of Efflux in July 2017 for which an escrow account was established to cover damages NetScout may suffer related to any liabilities that NetScout did not agree to assume or as a result of the breach of representations and warranties of the seller as described in the merger agreement. The $523 thousand was paid to the sellers in July 2018.

Legal – From time to time, NetScout is subject to legal proceedings and claims in the ordinary course of business. In the opinion of management, the amount of ultimate expense with respect to any current legal proceedings and claims, if determined adversely, will not have a material adverse effect on the Company’s financial condition, results of operations or cash flows.

As previously disclosed, in March 2016, Packet Intelligence LLC (“Packet Intelligence” or “Plaintiff”) filed a Complaint against NetScout and two subsidiary entities in the United States District Court for the Eastern District of Texas asserting infringement of five United States patents. Plaintiff’s Complaint alleged that legacy Tektronix GeoProbe products, including the G10 and GeoBlade products, infringed these patents. NetScout filed an Answer denying Plaintiff’s allegations and asserting that Plaintiff’s patents were, among other things, invalid, not infringed, and unenforceable due to inequitable conduct. In October 2017, a jury trial was held to address the parties’ claims and counterclaims regarding infringement of three patents by the G10 and GeoBlade products, invalidity of these patents, and damages. On October 13, 2017, the jury rendered a verdict finding in favor of the Plaintiff and that Plaintiff was entitled to $3,500,000 for pre-suit damages and $2,250,000 for post-suit damages. The jury indicated that the awarded damages amounts were intended to reflect a running royalty. The Court also conducted a bench trial on whether these patents were unenforceable due to, among other things, inequitable conduct. The Court has not yet rendered a decision on the equitable issues or entered final judgment in this matter. NetScout has concluded that the risk of loss from this matter is currently neither remote nor probable, and therefore, under GAAP definitions, the risk of loss is termed "reasonably possible". Therefore, accounting rules require NetScout to provide an estimate for the range of potential liability. Netscout currently estimates that the estimated range of liability is between $0 and the aggregate amount awarded by the jury, plus potential additional pre- and post-judgment interest amounts, subject to other adjustments that the Court may make. NetScout intends to continue to vigorously dispute Packet Intelligence’s claims including through appeal, if necessary.

NOTE 14 – PENSION BENEFIT PLANS

Certain of the Company's non-U.S. employees participate in certain noncontributory defined benefit pension plans acquired in the Comms Transaction on July 14, 2015. None of the Company's employees in the U.S. participate in any noncontributory defined benefit pension plans. In general, these plans are funded based on considerations relating to legal requirements, underlying asset returns, the plan's funded status, the anticipated deductibility of the contribution, local practices, market conditions, interest rates and other factors.

The following sets forth the components of the Company's net periodic pension cost of the noncontributory defined benefit pension plans for the three months ended June 30, 2018 and 2017 (in thousands):



	Three Months Ended
	June 30,
	2018		2017
Service cost	$	63	$	197
Interest cost	121		381
Net periodic pension cost	$	184	$	578

Expected Contributions

During the three months ended June 30, 2018, the Company made contributions of $0.1 million to its defined benefit pension plans. During the fiscal year ending March 31, 2019, the Company's cash contribution requirements for its defined benefit pension plans are expected to be less than $1.0 million. As a majority of the participants within the Company's plans are all active employees, the benefit payments are not expected to be material in the foreseeable future.

NOTE 15 – TREASURY STOCK

On May 19, 2015, the Company's board of directors approved a share repurchase program, conditional upon the completion of the Comms Transaction. This program enabled the Company to repurchase up to 20 million shares of its common stock. This plan became effective on July 14, 2015 upon the completion of the Comms Transaction. The Company was not obligated to acquire any specific amount of common stock within any particular timeframe under this program. The Company repurchased 2,780,433 shares for $100.0 million under this program during the three months ended June 30, 2017. Through March 31, 2018, the Company had repurchased 20,000,000 shares totaling $607.6 million in the open market under this stock repurchase plan. At March 31, 2018, there were no shares of common stock that remained available to be purchased under the plan.

On October 24, 2017, the Company’s Board of Directors approved a new share repurchase program that enables the Company to repurchase up to twenty-five million shares of its common stock. This new program became effective when the Company’s previously disclosed twenty million share repurchase program was completed. The Company is not obligated to acquire any specific amount of common stock within any particular timeframe as a result of this new share repurchase program.

On February 1, 2018, the Company entered into ASR agreements with two third-party financial institutions (the Dealers) to repurchase an aggregate of $300 million of the Company's common stock via accelerated stock repurchase transactions under the Company’s twenty million share repurchase program and the twenty-five million share repurchase program. The Company borrowed $300 million against its Amended Credit Facility to finance the payment of the initial purchase price to each of the Dealers. Under the terms of the ASR, the Company made a $150 million payment to each of the Dealers on February 2, 2018, and received an initial delivery of 3,693,931 shares from each of the Dealers, or 7,387,862 shares in the aggregate, which is approximately 70 percent of the total number of shares of the Company's common stock expected to be repurchased under the ASR. As part of this purchase, 970,650 shares for $27.6 million were deducted under the twenty million share repurchase program and 6,417,212 shares for $182.4 million were deducted from the twenty-five million share repurchase program during the fiscal year ended March 31, 2018. The final number of ASR shares is dependent upon the average of the daily volume-weighted average prices of the Company’s common stock during the term of the ASR, less a discount and subject to adjustments pursuant to the terms and conditions of the ASR. The delivery of additional shares of common stock to the Company or an additional delivery of shares of common stock or a cash payment, at NetScout's election, by the Company to the Dealers may be required. The final settlement of each of the ASR transactions is expected to occur no later than the end of the second quarter of fiscal year 2019.

At June 30, 2018, 18,582,788 shares of common stock remained available to be purchased under the current program.

In connection with the delivery of common shares upon vesting of restricted stock units, the Company withheld 129,115 shares at a cost of $3.5 million related to minimum statutory tax withholding requirements on these restricted stock units during the three months ended June 30, 2018. 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.

NOTE 16 – NET LOSS PER SHARE

Calculations of the basic and diluted net loss per share and potential common shares are as follows (in thousands, except for per share data):

Net loss per share:
Basic net loss per share	$	(0.78	)	$	(0.27	)
Diluted net loss per share	$	(0.78	)	$	(0.27	)

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



	Three Months Ended
	June 30,
	2018	2017
Restricted stock units	1,065	1,029

Basic net loss per share is calculated by dividing net 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 loss per share is calculated by dividing net 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 and unrecognized compensation expense as additional proceeds. As we incurred a net loss for the three months ended June 30, 2018 and 2017, all outstanding restricted stock units have an anti-dilutive effect and are therefore excluded from the computation of diluted weighted average shares outstanding.

The delivery of approximately 7.4 million shares under the Company's accelerated share repurchase (ASR) agreements reduced our outstanding shares used to determine our weighted average common shares outstanding for purposes of calculating basic and diluted earnings per share for the three months ended June 30, 2018. See Note 15 for additional information. We evaluated the ASR agreements for potential dilutive effects of any shares remaining to be received or owed upon settlement and determined the additional shares to be received would be anti-dilutive, and therefore they were not included in our calculation of diluted earnings per share for the three months ended June 30, 2018.

NOTE 17 – INCOME TAXES

The Company's effective income tax rates were 23.5% and 34.0% for the three months ended June 30, 2018 and 2017, respectively. Generally, the effective tax rate differs from the statutory tax rate due to the impact of the 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 June 30, 2018 is lower than the effective rate for the three months ended June 30, 2017, primarily due to the enactment of the Tax Legislation and a significant decrease in pre-tax earnings.

Table of Contents

On December 22, 2017, the Tax Legislation was signed into law. The Tax Legislation significantly revises the U.S. tax code by, among other things, lowering the corporate tax rate from 35% to 21%; imposing a minimum tax on certain foreign earnings; limiting the deductibility of interest expense; implementing a territorial tax system and repealing the domestic production activities deduction. In December 2017, the SEC issued Staff Accounting Bulletin No. 118 (SAB 118), which addresses situations where the accounting is incomplete for the income tax effects of the Tax Legislation. SAB 118 directs taxpayers to consider the impact of the Tax Legislation as “provisional” when the Company does not have the necessary information available, prepared or analyzed (including computations) to finalize the accounting for the change in tax law. Companies are provided a measurement period of up to one year to obtain, prepare, and analyze information necessary to finalize the accounting for provisional amounts or amounts that could not be estimated as of December 31, 2017.

While the Company continues to assess the impact of the Tax Legislation on its consolidated financial statements, the Company has not recorded any adjustments to the provisional amounts recorded through June 30, 2018. The Company is still in the process of analyzing the impact of the Tax Legislation, including any potential impact on its indefinite reinvestment assertion.

The Company is subject to the tax on the Global Intangible Low-Taxed Income (GILTI) but has not completed its analysis of the applicability of the tax. As of June 30, 2018, the Company is still evaluating the effects of the GILTI provisions as guidance and interpretations continue to develop. Therefore, the Company will not make a policy election on how to account for GILTI (as part of deferred taxes or as a period expense) until management has received and evaluated the necessary information. However, the standard requires that the Company reflects the impact of the GILTI provisions as a period expense until the accounting policy is finalized. Accordingly, the Company has included the provisional estimate of GILTI in its estimated annual effective tax rate and will update the impact and accounting policy once the analysis related to the GILTI provisions is complete.

NOTE 18 – SEGMENT AND GEOGRAPHIC INFORMATION

The Company reports revenues and income 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
	June 30,
	2018		2017
United States	$	127,246	$	138,618
Europe	31,021		35,448
Asia	17,900		19,527
Rest of the world	28,944		32,163
	$	205,111	$	225,756

The United States revenue includes sales to resellers in the United States. These resellers fulfill customer orders and may subsequently ship the Company’s products to international locations. The Company reports these shipments as United States revenue because the Company ships the products to a United States location. Further, the Company determines the geography of its sales after considering where the contract originated. A majority of revenue attributable to locations outside of the United States is a result of export sales. Substantially all of the Company's identifiable assets are located in the United States.

NOTE 19 - RELATED PARTY TRANSACTIONS

During our fiscal year ended March 31, 2016, a member of the Company's Board of Directors served as an executive officer of Danaher. As part of the split off of Danaher's Communications Business and the Company's subsequent acquisition of that business from Newco's shareholders, NetScout has entered into multiple transactions with Danaher which include: transition services agreements, lease agreements, closing agreements, and compensation for post-combination services provisions within the separation and distribution agreement. This board member is now the founding President and CEO of Fortive Corporation (Fortive), which spun off of Danaher in July 2016. As part of the spin-off of Fortive, the transition services agreement was amended to, among other things, assign Danaher's rights, duties, obligations and liabilities under the transition services agreement to Fluke Corporation, a subsidiary of Fortive. The Company has disclosed the transactions with Danaher and Fortive parenthetically within the financial statements.

Our solutions are typically deployed by customers as integrated hardware and software, as software only for use in commercial-off-the-shelf hardware or in a virtualized form factor.

Our operating results are influenced by a number of factors, including, but not limited to, the mix and quantity of products and services sold, pricing, costs of materials used in our products, growth in employee-related costs, including commissions, and the expansion of our operations. Factors that affect our ability to maximize our operating results include, but are not limited to, our ability to introduce and enhance existing products, the marketplace acceptance of those new or enhanced products, continued expansion into international markets, development of strategic partnerships, competition, successful acquisition integration efforts, and our ability to achieve expense reductions and make structural improvements in the current economic conditions.

Results Overview

Total revenue for the three months ended June 30, 2018 was primarily impacted by delays in the timing of orders by enterprise customers, ongoing declines in certain ancillary enterprise product lines and lower DDoS orders primarily by service provider customers.

Our gross profit percentage decreased by one percentage point during the three months ended June 30, 2018 as compared with the three months ended June 30, 2017.

Net loss for the three months ended June 30, 2018 was $62.5 million, as compared with net loss for the three months ended June 30, 2017 of $24.2 million, resulting in an increase in net loss of $38.3 million, primarily due to a $35.9 million impairment charge of certain intangible assets related to the handheld network tools product area, which is currently in the process of being divested.

At June 30, 2018, cash, cash equivalents and marketable securities (current and non-current) totaled $459.1 million, an $11.3 million increase from $447.8 million at March 31, 2018 due primarily to cash provided by operations of $25.5 million partially offset by $6.5 million used for capital expenditures and $3.5 million used for tax withholdings on restricted stock units during the three months ended June 30, 2018.

Use of Non-GAAP Financial Measures

We supplement the United States generally accepted accounting principles (GAAP) financial measures we report in quarterly and annual earnings announcements, investor presentations and other investor communications by reporting the following non-GAAP measures: non-GAAP total revenue, non-GAAP product revenue, non-GAAP service revenue, non-GAAP gross profit, non-GAAP income from operations, non-GAAP operating margin, non-GAAP earnings before interest and other expense, income taxes, depreciation and amortization (EBITDA) from operations, non-GAAP net income, and non-GAAP net income per share (diluted). Non-GAAP revenue (total, product and service) eliminates the GAAP effects of acquisitions by adding back revenue related to deferred revenue revaluation, as well as revenue impacted by the amortization of acquired intangible assets. Non-GAAP gross profit includes the foregoing adjustments and also removes expenses related to the amortization of acquired intangible assets, stock-based compensation, certain expenses relating to acquisitions including depreciation costs, and business development and integration costs. Non-GAAP income from operations includes the foregoing adjustments and also removes compensation for post-combination services, restructuring charges, intangible asset impairment charges, and costs related to new accounting standard implementation. Non-GAAP EBITDA from operations includes the aforementioned items related to non-GAAP income from operations and also removes non-acquisition-related depreciation expense. Non-GAAP net income includes the foregoing adjustments and also removes expenses and or benefit related to share-based compensation and certain expenses relating to acquisitions including: compensation for post-combination services, business development charges, and depreciation expense, net of related income tax effects in addition to the provisional one-time impacts of the U.S. Tax Cuts and Jobs Act. 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.

These non-GAAP measures are not in accordance with GAAP, should not be considered an alternative for measures prepared in accordance with GAAP (revenue, gross profit, operating profit, net loss and diluted net loss 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 our 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 with 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 GAAP 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.

Please refer to the critical accounting policies set forth in our Annual Report on Form 10-K for the fiscal year ended March 31, 2018, filed with the Securities and Exchange Commission (SEC) on May 21, 2018, for a description of all of our critical accounting policies.

Table of Contents

The critical accounting policies included in our Annual Report on the Form 10-K for the fiscal year ended March 31, 2018 have not materially changed, other than the following:

The critical accounting policy entitled "Revenue Recognition" has been updated as described below to reflect the adoption of ASU 2014-09.

Revenue Recognition

We exercise judgment and use estimates in connection with determining the amounts of product and services revenues to be recognized in each accounting period.

We derive revenues primarily from the sale of network management tools and security solutions for service provider and enterprise customers, which include hardware, software and service offerings. The majority of our product sales consist of hardware products with embedded software that are essential to providing customers the intended functionality of the solutions. We also sell stand-alone software solutions to provide customers with enhanced functionality. In addition, we sell hardware bundled with a software license.

We account for revenue once a legally enforceable contract with a customer has been approved by the parties and the related promises to transfer products or services have been identified. A contract is defined by us as an arrangement with commercial substance identifying payment terms, each party’s rights and obligations regarding the products or services to be transferred and collection is probable. Customer contracts may include promises to transfer multiple products and services to a customer. Determining whether the products and services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation may require significant judgment. Revenue is recognized when control of the products or services are transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for products and services.

Product revenue is recognized upon shipment, provided a legally enforceable contract exists, control has passed to the customer, and in the case of software products, when the customer has the rights and ability to access the software, and collection of the related receivable is probable. 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. Our service offerings include installation, integration, extended warranty and maintenance services, post-contract customer support, stand-ready software-as-a-service (SAAS) and other professional services including consulting and training. We generally provide 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, bug fixes and hardware repair and replacement. Consulting services are recognized upon delivery or completion of performance depending on the terms of the underlying contract. SAAS services are recognized ratably over the contract term beginning on the commencement of services. 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, our 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.

Bundled arrangements are concurrent customer purchases of a combination of our product and service offerings that may be delivered at various points in time. We allocate the transaction price among the performance obligations in an amount that depicts the relative standalone selling prices (SSP) of each obligation. Judgment is required to determine the SSP for each distinct performance obligation. We use a range of amounts to estimate SSP when we sell each of the products and services separately based on the element’s historical pricing. We also consider our overall pricing objectives and practices across different sales channels and geographies, and market conditions. Generally, we have established SSP for a majority of our service elements based on historical standalone sales. In certain instances, we have established SSP for services based upon an estimate of profitability and the underlying cost to fulfill those services. Further, for certain service engagements we consider quoted prices as part of multi-element arrangements of these engagements as a basis for establishing SSP. SSP has been established 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. We review sales of the product elements on a quarterly basis and update, when appropriate, our SSP for such elements to ensure that it reflects recent pricing experience. Our products are distributed through our direct sales force and indirect distribution channels through alliances with resellers and distributors. Revenue arrangements with resellers and distributors are recognized on a sell-in basis; that is, when we deliver the product to the reseller or distributor. We record consideration given to a reseller or distributor as a reduction of revenue to the extent we have recorded revenue from the reseller or distributor. With limited exceptions, our return policy does not allow product returns for a refund. Returns have been insignificant to date. In addition, we have a history of successfully collecting receivables from our resellers and distributors.

Three Months Ended June 30, 2018 and 2017

Revenue

Product revenue consists of sales of our hardware products and licensing of our software products. Service revenue consists of customer support agreements, consulting, training and stand-ready software-as-a-service. During the three months ended June 30, 2018 and 2017, no direct customer or indirect channel partner accounted for more than 10% of our total revenue.

Total revenue	$	205,111	100	%	$	225,756	100	%	$	(20,645	)	(9	)%

Product. The 11%, or $11.7 million, decrease in product revenue compared with the same period last year was largely due to a decrease in revenue from service provider products in the security reporting unit, partially offset by a $5.7 million increase related to the adoption of Topic 606.

Going forward, we believe that the challenging market conditions that have impacted recent performance, including from service provider capital spending pressures and enterprise customers’ uncertainty around digital transformation initiatives, are likely to persist. These dynamics have manifested in longer sales cycles, order delays and changes in order volumes. To effectively navigate these market conditions and ultimately improve revenue performance, we have made substantial investments in recent years to enhance and expand our product portfolio, thereby increasing our total addressable market and elevating our value proposition to customers.

Service. The 8%, or $8.9 million, decrease in service revenue compared with the same period last year was due to a $3.9 million decrease related to the adoption of Topic 606 as well as a decrease in maintenance contracts. We expect service revenue will continue to decline due to the adoption of Topic 606 and lower professional services revenue.

Total revenue by geography is as follows:

Total revenue	$	205,111	100	%	$	225,756	100	%	$	(20,645	)	(9	)%

United States revenue decreased 8%, or $11.4 million, compared with the same period last year primarily due to the decrease in security revenue from service provider customers and, to a lesser extent, lower service assurance revenue from enterprise customers related to various ancillary products. The 11%, or $9.3 million, decrease in international revenue compared with the same period last year was primarily driven by lower security revenue from both service provider and

enterprise customers. 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.

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 developed technology and core technology. Cost of service revenue consists primarily of personnel, material, overhead and support costs.

Product. The 10%, or $3.5 million, decrease in cost of product revenue was primarily due to a $3.6 million decrease in direct material costs due to the shifts in product mix and the decrease in product revenue, a $1.1 million decrease in employee-related expenses, an $0.8 million decrease in the amortization of intangible assets and a $0.4 million decrease in business development expenses. These decreases were partially offset by a $1.3 million increase in inventory obsolescence charges, a $0.5 million increase in capitalized overhead costs and a $0.3 million increase in contractor fees. The product gross profit percentage remained flat at 66% during the three months ended June 30, 2018 as compared with the three months ended June 30, 2017. The 11%, or $8.2 million, decrease in product gross profit corresponds with the 11%, or $11.7 million, decrease in product revenue partially offset by the 10%, or $3.5 million, decrease in cost of product revenue. Average headcount in manufacturing was 105 and 92 for the three months ended June 30, 2018 and 2017, respectively.

Service. The 3%, or $1.0 million, decrease in cost of service revenue during the three months ended June 30, 2018 when compared with the three months ended June 30, 2017 was primarily due to a $1.0 million decrease in contractor fees, a $0.6 million decrease in business development expenses and a $0.5 million decrease in travel expenses. These decreases were partially offset by a $1.4 million increase in employee-related expenses. The service gross profit percentage decreased by one percentage point to 73% for the three months ended June 30, 2018 as compared with the three months ended June 30, 2017. The 9%, or $7.9 million, decrease in service gross profit corresponds with the 8%, or $8.9 million, decrease in service revenue, partially offset the 3%, or $1.0 million, decrease in cost of service. Average headcount in service was 602 and 609 for the three months ended June 30, 2018 and 2017, respectively.

Gross profit. Our gross profit decreased 10%, or $16.1 million, during the three months ended June 30, 2018 when compared with the three months ended June 30, 2017. This decrease is attributable to the decrease in revenue of 9%, or $20.6 million, partially offset by the 7%, or $4.5 million, decrease in cost of revenue. The gross profit percentage decreased one percentage point to 70% for the three months ended June 30, 2018 as compared with the three months ended June 30, 2017.

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 6%, or $3.5 million, decrease in research and development expenses was due to a $1.1 million decrease in non-recurring business development expenses in the three months ended June 30, 2018, a $1.0 million decrease in employee-related expenses due to a decrease in headcount, a $0.7 million decrease in depreciation expense and a $0.5 million decrease in travel expense when compared with the three months ended June 30, 2017. Average headcount in research and development was 1,088 and 1,200 for the three months ended June 30, 2018 and 2017, 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 8%, or $7.2 million, decrease in total sales and marketing expenses was primarily due to a $2.2 million decrease in commission expense, a $1.6 million decrease in trade shows and other marketing related programs, a $1.2 million decrease in non-recurring business development expenses in the three months ended June 30, 2018, a $0.7 million decrease in employee-related expenses due to a decrease in headcount, a $0.4 million decrease in consulting fees and a $0.3 million decrease in advertising expense when compared with the three months ended June 30, 2017. Average headcount in sales and marketing was 882 and 950 for the three months ended June 30, 2018 and 2017, 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 13%, or $3.8 million, decrease in general and administrative expenses was primarily due to a $2.2 million decrease in business development expenses, a $0.8 million decrease in tax related items, a $0.7 million decrease in depreciation expense, a $0.7 million decrease in legal expense and a $0.4 million decrease in employee-related expenses primarily due to a decrease in headcount. These decreases were partially offset by a $0.6 million increase in bad debt expense when compared with the three months ended June 30, 2017. Average headcount in general and administrative was 264 and 278 for the three months ended June 30, 2018 and 2017, respectively.

Amortization of acquired intangible assets. Amortization of acquired intangible assets consists primarily of amortization of customer relationships, definite-lived trademarks and tradenames, and leasehold interests; related to the acquisition of Danaher Corporation's Communications Business, which included certain assets, liabilities, technology and employees within Tektronix Communications, VSS Monitoring, Arbor Networks and certain portions of the Fluke Networks Enterprise business, which excluded Danaher's data communications cable installation business and its communication service provider business (the Comms Transaction), ONPATH Technologies, Inc., Simena, LLC (Simena), Psytechnics, Ltd, Network General Corporation, Avvasi Inc. and Efflux Systems, Inc (Efflux).

The 28%, or $5.1 million, increase in amortization of acquired intangible assets was due to an increase of $5.0 million due to the acceleration of certain intangibles related to the Comms Transaction.

Table of Contents

Impairment of intangible assets. During the three months ended June 30, 2018 we performed a quantitative analysis on certain intangible assets related to the handheld network tools product area, which is currently in the process of being divested. The fair value of these intangible assets was determined to be less than the carrying value, and as a result, the Company recognized an impairment charge of $35.9 million during the three months ended June 30, 2018.

Restructuring. During fiscal year 2018 and 2017, we restructured certain departments to better align functions, drive productivity and improve efficiency. As a result of the restructuring programs, we recorded $1.1 million of restructuring charges related to costs to be paid to employees for one-time termination benefits as well as facility-related charges during the three months ended June 30, 2018, and $0.2 million of restructuring charges related to severance costs paid to employees during the three months ended June 30, 2017.

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.

Interest and other expense, net	$	(4,693	)	(2	)%	$	(3,135	)	(1	)%	$	(1,558	)	(50	)%

The 50%, or $1.6 million, increase in interest and other expense, net was primarily due to a $3.3 million increase in interest expense due to additional amounts drawn down on the credit facility entered into on January 16, 2018 as well as an increase in the average interest rate on the credit facility. This increase was partially offset by an $0.8 million decrease in foreign exchange expense, a $0.5 increase in interest income and a $0.4 million decrease in loss on the disposal of fixed assets.

Income Taxes. Our effective income tax rates were 23.5% and 34.0% for the three months ended June 30, 2018 and 2017, respectively. Generally, the effective tax rate differs from the statutory tax rate due to the impact of the 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 June 30, 2018 is lower than the effective rate for the three months ended June 30, 2017, primarily due to the enactment of the Tax Cuts and Jobs Act (Tax Legislation) and a significant decrease in pre-tax earnings.

On December 22, 2017, the Tax Legislation was signed into law. The Tax Legislation significantly revises the U.S. tax code by, among other things, lowering the corporate tax rate from 35% to 21%; imposing a minimum tax on certain foreign earnings; limiting the deductibility of interest expense; implementing a territorial tax system and repealing the domestic production activities deduction. In December 2017, the SEC issued Staff Accounting Bulletin No. 118 (SAB 118), which addresses situations where the accounting is incomplete for the income tax effects of the Tax Legislation. SAB 118 directs taxpayers to consider the impact of the Tax Legislation as "provisional" when the Company does not have the necessary information available, prepared or analyzed (including computations) to finalize the accounting for the change in tax law. Companies are provided a measurement period of up to one year to obtain, prepare, and analyze information necessary to finalize the accounting for provisional amounts or amounts that could not be estimated as of December 31, 2017.

While the Company continues to assess the impact of the Tax Legislation on its consolidated financial statements, the Company has not recorded any adjustments to the provisional amounts recorded through June 30, 2018. The Company is still in the process of analyzing the impact of the Tax Legislation, including the impact on its indefinite reinvestment assertion.

Off-Balance Sheet Arrangements

At June 30, 2018 and 2017, we did not have any off-balance sheet arrangements as defined in Regulation S-K, Item 303(a)(4)(ii).

Commitments 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.

Acquisition related – We have a contingent liability related to the acquisition of Simena in November 2011 for future consideration to be paid to the seller which had an initial fair value of $8.0 million at the time of acquisition. At June 30, 2018, the present value of the future consideration was $5.0 million.

Legal – From time to time, NetScout is subject to legal proceedings and claims in the ordinary course of business. In the opinion of management, the amount of ultimate expense with respect to any current legal proceedings and claims, if determined adversely, will not have a material adverse effect on our financial condition, results of operations or cash flows.

Cash, cash equivalents and marketable securities

At June 30, 2018, cash, cash equivalents and marketable securities (current and non-current) totaled $459.1 million, an $11.3 million increase from $447.8 million at March 31, 2018, due primarily to cash provided by operations of $25.5 million partially offset by $6.5 million used for capital expenditures and $3.5 million used for tax withholdings on restricted stock units during the three months ended June 30, 2018.

At June 30, 2018, cash and short-term and long-term investments in the United States were $294.0 million, while cash held outside the United States was approximately $165.1 million.

Cash and cash equivalents were impacted by the following (in thousands):

Net cash provided by operating activities	$	25,520		$	52,635

Net cash used in financing activities	$	(3,486	)	$	(105,381	)

Net cash from operating activities

Cash provided by operating activities was $25.5 million during the three months ended June 30, 2018, compared with $52.6 million of cash provided by operating activities during the three months ended June 30, 2017. This $27.1 million decrease was due in part to a $61.6 million unfavorable impact from accounts receivable, a $38.3 million decrease from net income, a $5.7 million decrease from deferred income taxes, a $2.3 million decrease from prepaid expenses and other assets and a $2.1 million decrease from income taxes payable. These decreases were partially offset by a $35.9 million increase due to the impairment of intangible assets, a $26.4 million increase in accrued compensation and other expenses, an $8.1 million increase from deferred revenue, a $4.6 million increase in inventories, a $2.7 million increase from share-based compensation, and a $2.6 million increase from depreciation and amortization in the three months ended June 30, 2018 as compared with the three months ended June 30, 2017.

Table of Contents

Cash used in investing activities increased by $42.7 million to $34.1 million during the three months ended June 30, 2018, compared with $8.6 million of cash provided by investing activities during the three months ended June 30, 2017.

The overall decrease in cash inflow from marketable securities was primarily related to an increase of $33.8 million in the purchases of marketable securities and a $5.7 million decrease in proceeds from the maturity of marketable securities during the three months ended June 30, 2018 when compared with the three months ended June 30, 2017. These were partially offset by a $3.2 million increase in the purchase of fixed assets primarily related to higher capital expenditures associated with the relocation and build-out of a new facility.

Our investments in property and equipment consist primarily of computer equipment, demonstration units, office equipment and facility improvements. We plan to continue to invest in capital expenditures to support our infrastructure through the remainder of fiscal year 2019.

Net cash from financing activities



	Three Months Ended
	June 30,
	(Dollars in Thousands)
	2018			2017
Cash used in financing activities included the following:
Treasury stock repurchases	—			(100,000		)
Tax withholding on restricted stock units	(3,486		)	(5,381		)
	$	(3,486	)	$	(105,381	)

Cash used in financing activities decreased by $101.9 million to $3.5 million during the three months ended June 30, 2018, compared with $105.4 million of cash used in financing activities during the three months ended June 30, 2017.

This decrease is primarily due to the fact that we repurchased 2,780,433 shares of our common stock for $100.0 million under our stock repurchase program during the three months ended June 30, 2017, and did not repurchase any shares of our common stock during the three months ended June 30, 2018.

In connection with the delivery of common shares upon vesting of restricted stock units, we have withheld 129,115 and 147,179 shares at a cost of $3.5 million and $5.4 million related to minimum statutory tax withholding requirements on these restricted stock units during the three months ended June 30, 2018 and 2017, respectively. These withholding transactions do not fall under the repurchase program described above, and therefore do not reduce the amount of shares that are available for repurchase under that program.

Credit Facility

On January 16, 2018, we amended and expanded our existing credit agreement (Amended Credit Agreement) with a syndicate of lenders by and among: NetScout; 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; Fifth Third Bank, Santander Bank, N.A., SunTrust Bank, N.A. and U.S. Bank National Association, as co-documentation agents; and the lenders party thereto.

The Amended Credit Agreement provides for a five-year $1.0 billion senior secured revolving credit facility, including a letter of credit sub-facility of up to $75.0 million. We may elect to use the new credit facility for general corporate purposes or to finance the repurchase of common stock under our common stock repurchase plan. The commitments under the Amended Credit Agreement will expire on January 16, 2023, and any outstanding loans will be due on that date.

On February 1, 2018, we also announced that we entered into agreements with JPMorgan Chase Bank, National Association and Bank of America, N.A. (the Dealers) to repurchase an aggregate of $300 million of our common stock via accelerated stock repurchase transactions (the ASR) under our previously disclosed share repurchase program. On February 1, 2018, we borrowed an additional $300 million aggregate principal amount under the Amended Credit Agreement in order to finance the payment of the ASR to each of the Dealers. At June 30, 2018, $600 million was outstanding under the Amended Credit Agreement.

At our election, revolving loans under the Amended Credit Agreement bear interest at either (a) an Alternate Base Rate per annum equal to the greatest of (1) JPMorgan’s prime rate, (2) 0.50% in excess of the New York Federal Reserve Bank (NYFRB) rate, or (3) an adjusted one month LIBOR rate plus 1%; or (b) such adjusted LIBOR rate (for the interest period selected by us), in each case plus an applicable margin. For the period from the delivery of our financial statements for the

Table of Contents

quarter ended March 31, 2018, until we have delivered financial statements for the quarter ended June 30, 2018, the applicable margin will be 1.50% per annum for LIBOR loans and 0.50% per annum for Alternate Base Rate loans, and thereafter the applicable margin will vary depending on our 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 3.50 to 1.00, down to 0.00% per annum for Alternate Base Rate loans and 1.00% per annum for LIBOR loans if our consolidated leverage ratio is equal to or less than 1.50 to 1.00.

Our consolidated leverage ratio is the ratio of our total funded debt compared to our 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 adjusted EBITDA in the Amended Credit Agreement.

Commitment fees will accrue on the daily unused amount of the credit facility. For the period from the delivery of our financial statements for the quarter ended March 31, 2018 until we have delivered financial statements for the quarter ended June 30, 2018, the commitment fee will be 0.25% per annum, and thereafter the commitment fee will vary depending on our consolidated leverage ratio, ranging from 0.30% per annum if our consolidated leverage ratio is greater than 2.75 to 1.00, down to 0.15% per annum if our consolidated leverage ratio is equal to or less than 1.50 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 Amended 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 us 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. We may also prepay loans under the Amended 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 our wholly owned material domestic restricted subsidiaries, subject to certain exceptions, and (b) are secured by substantially all of the assets of us and the subsidiary guarantors, including a pledge of all the capital stock of material subsidiaries held directly by us 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 Amended Credit Agreement generally prohibits any other liens on the assets of NetScout and its restricted subsidiaries, subject to certain exceptions as described in the Amended Credit Agreement.

The Amended 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 Amended Credit Agreement. At June 30, 2018, we were in compliance with all of these covenants.

In connection with the Amended Credit Agreement described above, we terminated our previous term loan dated as of July 14, 2015, by and among NetScout; 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.

We have capitalized debt issuance costs totaling $12.2 million at June 30, 2018, which are being amortized over the life of the revolving credit facility. The unamortized balance was $7.9 million as of June 30, 2018. The balance of $1.7 million

was included as prepaid expenses and other current assets and a balance of $6.2 million was included as other assets in our consolidated balance sheet.

Expectations for Fiscal Year 2019

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. We expect that cash provided by operating activities in fiscal year 2019 will be lower than cash provided by operations in fiscal year 2018 due to changes in working capital.

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.

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 June 30, 2018, we owed $600 million on this loan with an interest rate of 3.60%. A sensitivity analysis was performed on the outstanding portion of our debt obligation as of June 30, 2018. Should the current weighted-average interest rate increase or decrease by 10%, the resulting annual increase or decrease to interest expense would be approximately $2.2 million as of June 30, 2018.

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.

At June 30, 2018, we had foreign currency forward contracts with notional amounts totaling $10.1 million. The valuation of outstanding foreign currency forward contracts at June 30, 2018 resulted in a liability balance of $381 thousand, reflecting unfavorable contract rates in comparison to current market rates at this date. At March 31, 2018, we had foreign currency forward contracts with notional amounts totaling $11.2 million. The valuation of outstanding foreign currency forward contracts at March 31, 2018 resulted in a liability balance of $40 thousand, reflecting unfavorable contract rates in comparison to current market rates at this date and an asset balance of $122 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 June 30, 2018, 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 (as defined in Rule 13a-15(e) and 15d-15(e) 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 June 30, 2018, our disclosure controls and procedures were effective at the reasonable assurance level 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.

Except for the implementation of certain internal controls related to the adoption of Topic 606, there were no other changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) occurred during the period covered by this quarterly report 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 be material to 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, 2018. The risks discussed in our Annual Report on Form 10-K could materially affect our business, financial condition and future results. There have been no material changes to those risk factors since we filed our Annual Report on Form 10-K. The risks described in our Annual Report on Form 10-K 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.
