Basis of Presentation

The year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, the unaudited consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, necessary for their fair statement in conformity with accounting principles generally accepted in the United States of America. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission. The information included in this Form 10-Q should be read in conjunction with Management’s Discussion and Analysis of Financial Condition and Results of Operations and financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, ~~2018~~.2019.

Certain prior year amounts have been reclassified to conform to the current year presentation in the Consolidated Statements of Cash Flows. The reclassified amounts are considered immaterial and there was no change to total cash from operating, investing or financing activities as a result.

There have been no material changes to ~~our~~the Company's significant accounting policies as of and for the three months ended December 31, ~~2018,~~2019, except for the accounting ~~policies~~policy for ~~revenue recognition, trade receivables and deferred contract costs~~leases that ~~were~~was updated as a result of adopting Accounting Standards Update ~~2014-09,~~ ~~Revenue from Contracts with Customers~~2016-02, Leases (Topic ~~606)~~842) (ASU ~~2014-09).~~2016-02) and related standards. For more information, refer to the ~~"Revenue Recognition" and~~ "Recently Adopted Accounting Standards" ~~sections~~section of Note 1 and Note 27 - ~~Revenue from Contracts with Customers.~~

~~Revenue Recognition~~

On October 1, 2018, the Company adopted the new revenue recognition standard by applying the modified retrospective approach to those contracts which were not completed as of October 1, 2018. Results for reporting periods beginning after October 1, 2018 are presented under the new revenue recognition standard, while prior period amounts are not adjusted and continue to be reported under the accounting standards in effect for the prior periods.

~~The Company sells products through distributors, resellers, and directly to end users. Revenue related to the Company's contracts with customers is recognized by following a five-step process:~~

~~Identify the contract(s) with a customer.~~ ~~Evidence of a contract generally consists of a purchase order issued pursuant to the terms and conditions of a distributor, reseller or end user agreement.~~

~~Identify the performance obligations in the contract.~~ Performance obligations are explicitly identified in the Company's contracts and include hardware-based software, software-only solutions, cloud-based subscription services as well as a broad range of service performance obligations including consulting, training, installation and maintenance.

~~Determine the transaction price.~~ The purchase price stated in an agreed upon purchase order is generally representative of the transaction price. The Company offers several programs in which customers are eligible for certain levels of rebates if certain conditions are met. When determining the transaction price, the Company considers the effects of any variable consideration.

~~Allocate the transaction price to the performance obligations in the contract.~~ ~~The transaction price in a contract is allocated based upon the relative standalone selling price of each distinct performance obligation identified in the contract.~~

~~Recognize revenue when (or as) the entity satisfies a performance obligation.~~ The Company satisfies performance obligations either over time or at a point in time as discussed in further detail below. Revenue is recognized at the time the related performance obligation is satisfied by transferring control of promised products and services to a customer.

~~The following is a description of the principal activities from which the Company generates revenue:~~

~~Product~~

Revenue from the sale of the Company's hardware and perpetual software products is generally recognized at a point in time when the product has been delivered and the customer is obligated to pay for the product. When rights of return are present and the Company cannot estimate returns, revenue is recognized when such rights of return lapse. Payment terms to domestic customers are generally net 30 days to net 45 days. Payment terms to international customers range from net 30 days to net 120 days based on normal and customary trade practices in the individual markets.

~~Subscription~~

The Company also offers several products by subscription, either through term-based license agreements or as a service through its cloud-based Silverline platform. Revenue for term-based license agreements is recognized at a point in time, when the Company delivers the software license to the customer and the subscription term has commenced. For the Company's software-as-a-service Silverline offerings, revenue is recognized ratably as the services are provided.

~~Support and professional services~~

Revenues for post-contract customer support (PCS) are recognized on a straight-line basis over the service contract term. PCS includes a limited period of telephone support, updates, repair or replacement of any failed product or component that fails during the term of the agreement, bug fixes and rights to upgrades, when and if available. Consulting services are customarily billed at fixed hourly rates, plus out-of-pocket expenses, and revenues are recognized as the consulting is completed. Similarly, training revenue is recognized as the training is completed.

~~Contract acquisition costs~~

Sales commissions earned by the Company's sales force are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions for initial service contracts and subscription offerings are deferred and then amortized as an expense on a straight-line basis over the period of benefit which management has determined to be 4.5 years and 3 years, respectively.

~~Significant Judgments~~

The Company’s contracts with customers often include promises to transfer multiple products and services. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment.

Judgment is also required to determine the standalone selling price (SSP) for each distinct performance obligation. The Company sells post-contract customer support (PCS), subscriptions and professional services on a standalone basis and can therefore use a population of historical standalone sales to determine fair value. For distinct performance obligations that the Company does not generally sell on a standalone basis (hardware and perpetual software), a combination of the adjusted market assessment approach and the expected cost plus a margin approach are used to estimate the SSP.

~~Cash, Cash Equivalents and Restricted Cash~~

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company invests its cash and cash equivalents in deposits with five major financial institutions, which, at times, may exceed federally insured limits. The Company has not experienced any losses on its cash and cash equivalents.

Amounts included in restricted cash represent those required to be set aside by a contractual agreement. The following table provides a reconciliation of the Company’s cash and cash equivalents and restricted cash reported within the consolidated balance sheets that sum to the total cash, cash equivalents and restricted cash shown in the Company’s consolidated statements of cash flows for the periods presented (in thousands):

~~Goodwill and Acquired Intangible Assets~~

Goodwill represents the excess purchase price over the estimated fair value of net assets acquired as of the acquisition date. The Company tests goodwill for impairment on an annual basis and between annual tests when impairment indicators are identified, and goodwill is written down when impaired. Goodwill was recorded in connection with various acquisitions in prior years. For its annual goodwill impairment test in all periods to date, the Company has operated under one reporting unit and the fair value of its reporting unit has been determined by the Company’s enterprise value. The Company performs its annual goodwill impairment test during the second fiscal quarter.

As part of the annual goodwill impairment test, the Company has the option to perform a qualitative assessment to determine whether further impairment testing is necessary. Examples of events and circumstances that might indicate that the reporting unit’s fair value is less than its carrying amount include macro-economic conditions such as deterioration in the entity’s operating environment or industry or market considerations; entity-specific events such as increasing costs, declining financial performance, or loss of key personnel; or other events such as a sustained decrease in the stock price on either an absolute basis or relative to peers. If, as a result of its qualitative assessment, it is more-likely-than-not (i.e. greater than 50% chance) that the fair value of the Company’s reporting unit is less than its carrying amount, the quantitative impairment test will be required. Otherwise, no further testing will be required. If the Company chooses to bypass the qualitative assessment, it completes a quantitative assessment in performing its annual impairment test.

For its annual impairment test performed in the second quarter of fiscal 2018, the Company completed a quantitative assessment and determined that there was no impairment of goodwill. The Company also considered potential impairment indicators of goodwill at December 31, 2018 and noted no indicators of impairment.

The Company's intangible assets subject to amortization are amortized using the straight-line method over their estimated useful lives, ranging from three to ten years. The Company evaluates the recoverability of intangible assets periodically by taking into account events or circumstances that may warrant revised estimates of useful lives or that indicate the asset may be impaired. The Company considered potential impairment indicators of acquired intangible assets at December 31, 2018 and noted no indicators of impairment.

~~Software Development Costs~~

The authoritative guidance requires certain internal software development costs related to software to be sold to be capitalized upon the establishment of technological feasibility. The Company's software development costs incurred subsequent to achieving technological feasibility have not been significant, and all software development costs have been expensed as research and development activities as incurred.

~~Internal Use Software~~

In accordance with the authoritative guidance, the Company capitalizes application development stage costs associated with the development of internal-use software and software developed related to its SaaS-based product offerings. The capitalized costs are then amortized over the estimated useful life of the software, which is generally three to five years, and are included in property and equipment in the accompanying consolidated balance sheets.

~~Stock-Based Compensation~~

The Company accounts for stock-based compensation using the straight-line attribution method for recognizing compensation expense. The Company recognized $38.7 million and $40.9 million of stock-based compensation expense for the three months ended ~~December 31, 2018~~ ~~and~~ ~~2017, respectively. As of~~ ~~December 31, 2018, there was $204.3 million of total unrecognized stock-based compensation cost, the majority of which will be recognized over the next~~ ~~two~~ ~~years. Going forward, stock-based compensation expenses may increase as the Company issues additional equity-based awards to continue to attract and retain key employees.~~

The Company issues incentive awards to its employees through stock-based compensation consisting of restricted stock units (RSUs). On October 31, 2018, the Company’s Board of Directors and Compensation Committee approved 774,313 RSUs to employees and executive officers pursuant to the Company’s annual equity awards program. The value of RSUs is determined using the fair value method, which in this case, is based on the number of shares granted and the quoted price of the Company’s common stock on the date of grant.

The Company recognizes compensation expense for only the portion of restricted stock units that are expected to vest. Therefore, the Company applies estimated forfeiture rates that are derived from historical employee termination behavior. Based on historical differences with forfeitures of stock-based awards granted to the Company’s executive officers and Board of Directors versus grants awarded to all other employees, the Company has developed separate forfeiture expectations for

these two groups. In determining the fair value of shares issued under the Employee Stock Purchase Plan (ESPP), the Company uses the Black-Scholes option pricing model. Compensation expense related to the shares issued pursuant to the ESPP is recognized on a straight-line basis over the offering period.

The Company issues incentive awards to certain current executive officers as part of its annual equity awards program. Fifty percent of the aggregate number of RSUs issued to executive officers vest in equal quarterly increments, and 50% are subject to the Company achieving specified performance goals.

For performance stock awards granted prior to fiscal 2018, attainment is based on the Company achieving specific quarterly revenue and EBITDA targets. In each case, 70% of the quarterly performance stock grant is based on achieving at least 80% of the quarterly revenue goal set by the Company's Board of Directors, and the other 30% is based on achieving at least 80% of the quarterly EBITDA goal set by the Company's Board of Directors. The quarterly performance stock grant is paid linearly over 80% of the targeted goals. At least 100% of both goals must be attained in order for the quarterly performance stock grant to be awarded over 100%. Each goal is evaluated individually and subject to the 80% achievement threshold and the 100% over-achievement threshold. Each goal is also capped at achievement of 200% above target.

For the fiscal 2018 and 2019 performance stock awards, the Company's Compensation Committee adopted a new set of metrics that are differentiated from the quarterly revenue and EBITDA measures, including (1) 50% of the annual performance stock grant is based on achieving 80% of the annual revenue goal set by the Company’s Board of Directors; (2) 25% of the annual performance stock grant is based on achieving at least a 18% increase in annual software revenue compared to the prior year; and (3) 25% of the annual performance stock grant is based on relative total shareholder return benchmarked to the S&P 500 index. In each case, no vesting or payment with respect to a performance goal shall occur unless a minimum threshold is met for the applicable goal. Vesting and payment with respect to the performance goal is linear above the threshold of the applicable goal and is capped at achievement of 200% above target.

~~As of December 31, 2018, the following annual equity grants for executive officers or a portion thereof are outstanding:~~



~~Grant Date~~	~~RSUs Granted~~	~~Vesting Schedule~~	~~Vesting Period~~	~~Date Fully Vested~~
~~November 1, 2018~~	~~144,066~~	~~Quarterly, Annually~~¹	~~3 years~~	~~November 1, 2021~~
~~November 1, 2017~~	~~140,135~~	~~Quarterly, Annually~~¹	~~4 years~~	~~November 1, 2021~~
~~November 1, 2016~~	~~115,347~~	~~Quarterly~~	~~4 years~~	~~November 1, 2020~~
~~November 2, 2015~~	~~145,508~~	~~Quarterly~~	~~4 years~~	~~November 1, 2019~~


~~(1)~~	~~50% of the annual equity grant vests in equal quarterly increments and 50% is subject to the Company achieving specified annual performance goals.~~

The Company recognizes compensation costs for awards with performance conditions when it concludes it is probable that the performance condition will be achieved. The Company reassesses the probability of vesting at each balance sheet date and adjusts compensation costs based on the probability assessment.

~~Common Stock Repurchase~~

On October 31, 2018, the Company announced that its Board of Directors authorized an additional $1.0 billion for its common stock share repurchase program. This new authorization is incremental to the existing $4.4 billion program, initially approved in October 2010 and expanded in each fiscal year. Acquisitions for the share repurchase programs will be made from time to time in private transactions or open market purchases as permitted by securities laws and other legal requirements. The programs can be terminated at any time. For the three months ended December 31, 2018, the Company repurchased and retired 568,758 shares at an average price of $177.64 per share and the Company had $1.5 billion remaining authorized to purchase shares at December 31, 2018.

~~Earnings Per Share~~

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of common and dilutive common stock equivalent shares outstanding during the period. The Company’s nonvested restricted stock awards and restricted stock units do not have nonforfeitable rights to dividends or dividend equivalents and are not considered participating securities that should be included in the computation of earnings per share under the two-class method.

~~The following table sets forth the computation of basic and diluted net income per share (in thousands, except per share data):~~

~~Anti-dilutive stock-based awards excluded from the calculations of diluted earnings per share were immaterial for the three months ended December 31, 2018 and 2017.~~

~~Comprehensive Income~~

Comprehensive income includes certain changes in equity that are excluded from net income. Specifically, unrealized gains or losses on securities and foreign currency translation adjustments are included in accumulated other comprehensive income or loss.Leases.

Recently Adopted Accounting Standards

~~In May 2014, the FASB issued ASU 2014-09,~~ ~~Revenue from Contracts with Customers (Topic 606)~~ (ASU 2014-09). ASU 2014-09 and the related amendments outline a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The new model requires revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The Company adopted this new accounting standard and the related amendments on October 1, 2018 using the modified retrospective method. See Note 2 - Revenue from Contracts with Customers for further details.

~~In August 2016, the FASB issued ASU 2016-15,~~ ~~Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments~~ (ASU 2016-15), which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. The Company adopted this new accounting standard on October 1, 2018. The adoption did not have an impact on the Company's condensed consolidated financial statements.

~~In November 2016, the FASB issued ASU 2016-18,~~ ~~Statement of Cash Flows (Topic 230): Restricted Cash~~ (ASU 2016-18), which requires a company’s cash flow statement to explain the changes during a reporting period of the totals for cash, cash equivalents, restricted cash and restricted cash equivalents. Additionally, amounts for restricted cash and restricted cash equivalents are to be included with cash and cash equivalents if the cash flow statement includes a reconciliation of the total cash balances for a reporting period. The Company adopted this new accounting standard on October 1, 2018, which resulted in an immaterial reclassification of beginning and ending cash, cash equivalents and restricted cash for the periods presented within the statement of cash flows. Upon adoption of this new standard, restricted cash activity is no longer separately presented within the investing activities in the statement of cash flows. The overall adoption of the standard did not have a material impact to the consolidated financial statements.

~~In January 2017, the FASB issued ASU 2017-01,~~ ~~Business Combinations (Topic 805): Clarifying the Definition of a Business~~ (ASU 2017-01), which provides a more robust framework to use in determining when a set of assets and activities is considered a business. The Company adopted this new accounting standard on October 1, 2018. The adoption did not have an impact on the Company's condensed consolidated financial statements.

~~In May 2017, the FASB issued ASU 2017-09,~~ ~~Compensation-Stock Compensation~~ (ASU 2017-09), which provides clarification on when modification accounting should be used for changes to the terms or conditions of a share-based payment award. This ASU does not change the accounting for modifications but clarifies that modification accounting guidance should only be applied if there is a change to the value, vesting conditions or award classification and would not be required if the

changes are considered non-substantive. The Company adopted this new accounting standard on October 1, 2018. The adoption did not have an impact on the Company's condensed consolidated financial statements.

~~Recently Issued Accounting Pronouncements~~

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (ASU 2016-02), which requires lessees to recognize on the balance sheet a right-of-use asset, representing its right to use the underlying asset for the lease term, and a corresponding lease liability for all leases with terms greater than twelve months. The Company’s leases consist primarily of operating leases for its ~~office~~offices and lab spaces. The Company does not have finance leases. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing and uncertainty of cash flows arising from leases. ~~Adoption of the new lease~~The Company adopted this standard ~~requires measurement of leases at the beginning of the earliest period presented~~on October 1, 2019 on a modified retrospective basis. The new standard will be effective for the Company beginning October 1, 2019. The Company anticipates that its long-term leases for office space will be recognized as lease liabilities and corresponding right-of-use assets, and will accordingly have a material impact on its consolidated balance sheets upon adoption.

~~In July 2018, the FASB issued ASU 2018-11, Leases (Topic 842) (ASU 2018-11), which provides an optional transition method to adopt ASU 2016-02, Leases (Topic 842)~~basis by ~~allowing lessees to apply~~applying the new standard ~~at the adoption date and recognize a cumulative-effect adjustment~~ to ~~the opening balance~~its lease portfolio as of ~~retained earnings~~October 1, 2019, while continuing to apply legacy guidance in the ~~period of adoption. Comparative periods will still be presented under current GAAP (ASC 840), along with the applicable Topic 840 disclosures for those~~ comparative periods. The ~~new standard is effective at the same time as~~ adoption of ~~ASU 2016-02,~~this standard had no impact on the consolidated income statements and consolidated statements of cash flows. Refer to Note 7 - Leases ~~(Topic 842), which~~for further discussion.

Upon adoption of the standard, the Company elected the package of three expedients for existing and expired contracts to not reassess: the existence of additional leases, lease classification, or the treatment of initial direct costs. The Company also applies the short-term lease exemption for leases with an original expected term of 12 months or less and expenses such leases month-to-month and does not record a right-of-use asset or lease liability. Short-term lease activity under the exception is ~~planning to adopt~~not significant. Additionally, the Company does not separate lease and non-lease components in the ~~first quarter~~allocation of ~~fiscal year 2020.~~ minimum lease payments for its office space and equipment leases, as such separation is not significant.

The Company ~~plans~~includes in minimum lease payments, fixed and variable payments based on a rate or index, but excludes variable payments based on satisfying future benchmarks or actual future costs incurred; such amounts are expensed as incurred. To calculate the net present value, the Company applied an incremental borrowing rate. This incremental borrowing rate is determined using a portfolio approach based on the rate of interest the Company would pay to ~~adopt~~borrow an amount equal to the ~~transitional provisions allowed under ASU 2018-11.~~lease payments on a collateralized basis over a similar term. Renewal options to extend lease terms are excluded from the minimum lease term at lease commencement.

Recently Issued Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13), which replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. The Company does not anticipate that the adoption of this standard will have a material impact on its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) (ASU 2018-15), which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software, and hosting arrangements that include an internal use software license. The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this update. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted. The Company does not anticipate that the adoption of this standard will have a material impact on its consolidated financial statements.

3. Business Combinations

Fiscal Year 2019 Acquisition of Nginx, Inc.

On March 9, 2019, the Company entered into a Merger Agreement (the “Merger Agreement”) with Nginx, Inc. ("NGINX"), a provider of open source web server software and application delivery solutions. The transaction closed on May 8, 2019 with NGINX becoming a wholly-owned subsidiary of F5.

Pursuant to the Merger Agreement, at the effective time of the Merger, the capital stock of NGINX and the vested outstanding and unexercised stock options in NGINX were cancelled and converted to the right to receive approximately $643.2 million in cash, subject to certain adjustments and conditions set forth in the Merger Agreement, and the unvested stock options and restricted stock units in NGINX held by continuing employees of NGINX were assumed by F5, on the terms and conditions set forth in the Merger Agreement. Included in cash consideration was $19.0 million of transaction costs paid by F5 on behalf of NGINX. In addition, the Company incurred an additional $1.0 million of transaction costs associated with the acquisition which was included in General and Administrative expenses for fiscal 2019.

NGINX is an open source leader in application delivery. The combined company will enable multi-cloud application services across all environments, providing the ease-of-use and flexibility developers require while also delivering the scale, security, reliability and enterprise readiness network operations teams demand. As a result of the acquisition, the Company acquired all the assets and assumed all the liabilities of NGINX. The goodwill related to the NGINX acquisition is comprised primarily of expected synergies from combining operations and the acquired intangible assets that do not qualify for separate recognition. The results of operations of NGINX have been included in the Company’s consolidated financial statements from the date of acquisition.

The purchase price allocation is as follows (in thousands):



Assets acquired
Cash and cash equivalents	$	29,911
Fair value of tangible assets:
Accounts receivable	7,306
Other current assets	4,214
Property and equipment, net	1,822
Deferred tax assets	10,357
Intangible assets	89,300
Goodwill	509,414
Total assets acquired	$	652,324
Liabilities assumed
Accounts payable	$	(1,081	)
Deferred revenue	(4,000		)
Other liabilities	(4,035		)
Total liabilities assumed	$	(9,116	)
Net assets acquired	$	643,208

The allocation of the purchase price and the estimated useful lives associated with certain assets is as follows (in thousands):



			Estimated
	Amount		Useful Life
Net tangible assets	$	44,494	—
Identifiable intangible assets:
Developed technologies	62,500		7 years
Customer relationships	12,000		15 years
Trade name	14,500		7 years
Non-competition agreements	300		2 years
Goodwill	509,414		—
Total purchase price	$	643,208

The developed technology intangible asset will be amortized on a straight-line basis over its estimated useful life of seven years and included in cost of net product revenues. The trade names and customer relationships intangible assets will be amortized on a straight-line basis over their estimated useful lives of seven years and fifteen years, respectively, and included in sales and marketing expenses. The weighted average life of the amortizable intangible assets recognized from the NGINX merger was 8.1 years. The estimated useful lives for the acquired intangible assets were based on the expected future cash flows associated with the respective asset. Tax deductible goodwill based on the Company's preliminary calculation is $450.7 million.

Since the NGINX acquisition was completed on May 8, 2019, the F5 and NGINX teams have been rapidly executing a plan to integrate ongoing operations.

4. Fair Value Measurements

In accordance with the authoritative guidance on fair value measurements and disclosure under GAAP, the Company determines fair value using a fair value hierarchy that distinguishes between market participant assumptions developed based on market data obtained from sources independent of the reporting entity, and the reporting entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances and expands disclosure about fair value measurements.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date, essentially the exit price.

The levels of fair value hierarchy are:

Level 1: Quoted prices in active markets for identical assets and liabilities at the measurement date that the Company has the ability to access.

Level 2: Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3: Unobservable inputs for which there is little or no market data available. These inputs reflect management’s assumptions of what market participants would use in pricing the asset or liability.

Level 1 investments are valued based on quoted market prices in active markets and include the Company’s cash equivalent investments. Level 2 investments, which include investments that are valued based on quoted prices in markets that are not active, broker or dealer quotations, actual trade data, benchmark yields or alternative pricing sources with reasonable levels of price transparency, include the Company’s certificates of deposit, corporate bonds and notes, municipal bonds and notes, U.S. government securities, U.S. government agency securities and international government securities. Fair values for

the Company’s level 2 investments are based on similar assets without applying significant judgments. In addition, all of the Company’s level 2 investments have a sufficient level of trading volume to demonstrate that the fair values used are appropriate for these investments.

A financial instrument’s level within the fair value hierarchy is based upon the lowest level of any input that is significant to the fair value measurement. However, the determination of what constitutes “observable” requires significant judgment by the Company. The Company considers observable data to be market data which is readily available, regularly distributed or updated, reliable and verifiable, not proprietary, and provided by independent sources that are actively involved in the relevant market.

The Company’s financial assets measured at fair value on a recurring basis subject to the disclosure requirements at December 31, ~~2018~~2019, were as follows (in thousands):

The Company uses the fair value hierarchy for financial assets and liabilities. The carrying amounts of other current financial assets and other current financial liabilities approximate fair value due to their short-term nature.

The Company’s non-financial assets and liabilities, which include goodwill, intangible assets, and long-lived assets, are not required to be carried at fair value on a recurring basis. These non-financial assets and liabilities are measured at fair value on a non-recurring basis when there is an indicator of impairment, and they are recorded at fair value only when impairment is recognized. The Company reviews goodwill and intangible assets for impairment annually, during the second quarter of each fiscal year, or as circumstances indicate the possibility of impairment. The Company monitors the carrying value of long-lived assets for impairment whenever events or changes in circumstances indicate its carrying amount may not be recoverable. During the three months ended December 31, ~~2018~~2019 and ~~2017,~~2018, the Company did not recognize any impairment charges related to goodwill, intangible assets, or long-lived assets.

~~The carrying amounts of other current financial assets and other current financial liabilities approximate fair value due to their short-term nature.~~

6.8. Commitments and Contingencies

Guarantees and Product Warranties

In the normal course of business to facilitate sales of its products, the Company indemnifies other parties, including customers, resellers, lessors, and parties to other transactions with the Company, with respect to certain matters. The Company has agreed to hold the other party harmless against losses arising from a breach of representations or covenants, or out of intellectual property infringement or other claims made against certain parties. These agreements may limit the time within

which an indemnification claim can be made and the amount of the claim. The Company has entered into indemnification agreements with its officers and directors and certain other employees, and the Company’s bylaws contain similar indemnification obligations to the Company’s agents. It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement.

The Company generally offers warranties of one year for hardware for those customers without service contracts, with the option of purchasing additional warranty coverage in yearly increments. The Company accrues for warranty costs as part of its cost of sales based on associated material product costs and technical support labor costs. Accrued warranty costs as of December 31, ~~2018~~2019 and September 30, ~~2018~~2019 were not ~~considered~~ material.

Commitments

As of December 31, ~~2018,~~2019, the Company’s principal commitments consisted of obligations outstanding under operating leases. The Company leases its facilities under operating leases that expire at various dates through 2033. There have been no material changes in the Company's lease obligations compared to those discussed in Note 711 to its annual consolidated financial statements.

The Company currently has arrangements with contract manufacturers and other suppliers for the manufacturing of its products. The arrangement with the primary contract manufacturer allows them to procure component inventory on the Company’s behalf based on a rolling production forecast provided by the Company. The Company is obligated to the purchase of component inventory that the contract manufacturer procures in accordance with the forecast, unless it gives notice of order cancellation in advance of applicable lead times. There have been no material changes in the Company's inventory purchase obligations compared to those discussed in Note 711 to its annual consolidated financial statements.

Legal Proceedings

~~On April 4, 2016, the~~The Company ~~sued Radware, Inc.~~is not aware of any pending legal proceedings that, individually or in the ~~United States District Court for the Western District of Washington (the case was subsequently moved~~aggregate, are reasonably possible to the Northern District of California) accusing Radware of infringing three Company patents. The Company’s complaint seeks a jury trial and an unspecified amount of monetary damages, as well as interest, costs, and injunctive relief. Radware moved to dismiss the allegations of one patent, but the motion was denied. Radware filed inter partes review (IPR) petitions on all of the asserted Company patents, but the US Patent Office dismissed all of the petitions. Radware also filed a counterclaim asserting that the Company infringed one of its now-expired patents. The Company filed an IPR petition against Radware’s counterclaim patent that resulted in cancellation of all but four of the patent’s claims by the Patent Office. The Court then recently held that F5 does not infringe the four remaining claims. Accordingly, the case will proceed solely on F5's infringement claims against Radware. The Court has entered a schedule for trial in November of 2019.

In addition to the above referenced matters, the Company is subject to other legal proceedings, claims, and litigation arising in the ordinary course of business. Management believes that the Company has meritorious defenses to the allegations made in its pending cases and intends to vigorously defend these lawsuits; however, the Company is unable currently to determine the ultimate outcome of these or similar matters or the potential exposure to loss, if any. There are many uncertainties associated with any litigation and these actions or other third-party claims against the Company may cause it to incur costly litigation and/or substantial settlement charges that could have a material adverse effect on the ~~Company's~~Company’s business, operating results, or financial ~~condition, results of operations, and cash flows.~~

condition. The Company ~~records an accrual for loss contingencies for legal proceedings when it~~is subject to a variety of claims and suits that arise from time to time in the ordinary course of business. Although management currently believes that resolving claims against the Company, individually or in aggregate, will not have a material adverse impact on its financial statements, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future. Such claims, even if not meritorious, could result in the expenditure of significant financial and managerial resources.

Our tax provision for interim periods is determined using an ~~unfavorable outcome is both (a) probable and (b)~~estimated annual effective tax rate, adjusted for discrete items in the amount or range of any possible loss is reasonably estimable. The Company has not recorded an accrual for loss contingencies associated with the legal proceedings or the investigations discussed above.related period.

~~7. Income Taxes~~

The effective tax rate was ~~20.8%~~22.8% and ~~38.7%~~20.8% for the three months ended December 31, ~~2018~~2019 and ~~2017,~~2018, respectively. The increase in the effective tax rate for the three months ended December 31, ~~2018 and December 31, 2017 includes various impacts from the Tax Cuts and Jobs Act enacted on December 22, 2017. Significant impacts for~~2019 as compared to the three months ended December 31, 2018 include a further reduction in the U.S. federal income tax rate to 21%, a deduction for foreign derived intangible income, a tax on global intangible low taxed income, and repeal of the deduction for income attributable to domestic production activities. The three months ended December 31, 2017 included one-time charges for the deemed repatriation of undistributed foreign earnings, and for the remeasurement of the Company’s net deferred tax assets to reflect the change in the U.S. federal income tax rate when temporary differences are expected to reverse.

~~In accordance with SEC Staff Accounting Bulletin (“SAB”) No. 118, the Company recorded a provisional tax expense of $7.0 million related~~is primarily due to the deemed repatriation of undistributed foreign earnings in the period ended December 31, 2017. SAB No. 118 provided a one-year measurement period to complete the accounting. During the period ended December 31, 2018, the Company finalized the computations for the deemed repatriation of undistributed foreign earnings and did not record any adjustments to the provisional amounts previously recorded.tax impact from stock-based compensation.

At December 31, ~~2018,~~2019, the Company had ~~$33.5~~$44.1 million of unrecognized tax benefits that, if recognized, would affect the effective tax rate. It is anticipated that the Company’s existing liabilities for unrecognized tax benefits will change within the next twelve months due to audit settlements or the expiration of statutes of limitations. The Company does not expect these changes to be material to the consolidated financial statements. The Company recognizes interest and, if applicable, penalties for any uncertain tax positions as a component of income tax expense.

The Company and its subsidiaries are subject to U.S. federal income tax as well as the income tax of multiple state and foreign jurisdictions. The Company has concluded all U.S. federal income tax matters for fiscal years through September 30, ~~2014. The Company is currently under audit by the IRS for fiscal year 2016 and by various states for fiscal years 2014 through 2017.~~2015. Major jurisdictions where there are wholly owned subsidiaries of F5 Networks, Inc. which require income tax filings include the United Kingdom, Japan, Singapore, Australia, and ~~Australia.~~Israel. The earliest periods open for review by local taxing authorities are fiscal years ~~2017~~2018 for the United Kingdom, 2014 for Japan, 2015 for Singapore, 2015 for Australia, and 2013 for ~~Japan,~~Israel. The Company is currently under audit by various states for fiscal years 2014 through 2017 and by Israel for ~~Singapore, and 2014 for Australia.~~fiscal years 2013 to 2017. Within the next four fiscal quarters, the statute of limitations will begin to close on the fiscal year ~~2015~~2016 federal income tax return, fiscal years ~~2014~~2015 and ~~2015~~2016 state income tax returns, and fiscal years 2013 to ~~2017~~2018 foreign income tax returns.

~~8. Geographic Sales~~10. Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of common and ~~Significant Customers~~dilutive common stock equivalent shares outstanding during the period. The Company’s nonvested restricted units do not have nonforfeitable rights to dividends or dividend equivalents and are not considered participating securities that should be included in the computation of earnings per share under the two-class method.

The following table sets forth the computation of basic and diluted net income per share (in thousands, except per share data):

11. Segment Information

Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision-maker, or decision-making group, in deciding how to allocate resources and in assessing performance. Management has determined that the Company is organized as, and operates in, ~~one~~1 reportable operating segment: the development, marketing and sale of application services that optimize the security, performance and availability of network applications, servers and storage systems.

Revenues by Geographic Location and Other Information

The Company does business in ~~three~~3 main geographic regions: the Americas (primarily the United States); Europe, the Middle East, and Africa (EMEA); and the Asia Pacific region (APAC). The Company’s chief operating decision-maker reviews financial information presented on a consolidated basis accompanied by information about revenues by geographic region.

13. Subsequent Events

Acquisition of Shape Security, Inc.

On December 19, 2019, the Company entered into a Merger Agreement (the “Merger Agreement”) with Shape Security, Inc. ("Shape"), a provider of fraud and abuse prevention solutions. The transaction closed on January 24, 2020 with Shape becoming a wholly-owned subsidiary of F5.

Pursuant to the Merger Agreement, at the effective time of the Merger, the capital stock of Shape and the vested outstanding and unexercised stock options in Shape were cancelled and converted to the right to receive approximately $1.0 billion in cash, subject to certain adjustments and conditions set forth in the Merger Agreement, and the unvested stock options and restricted stock units in Shape held by continuing employees of Shape were assumed by F5, on the terms and conditions set forth in the Merger Agreement.

During the first quarter of 2020, the Company incurred approximately $4.0 million of acquisition and integration related expenses associated with the Shape acquisition, which is included within General and Administrative operating expenses in our Consolidated Income Statements.

As a result of limited access to Shape information required to prepare initial accounting, together with the limited time since the acquisition date and the effort required to conform the financial statements to the Company's practices and policies, the initial accounting for the business combination is incomplete at the time of this filing. As a result, the Company is unable to provide the amounts recognized as of the acquisition date for the major classes of assets acquired and liabilities assumed, pre-acquisition contingencies and goodwill. Also, the Company is unable to provide pro forma revenues and earnings of the combined entity. This information will be included in the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2020.

Term Credit Agreement

In connection with the acquisition of Shape, on January 24, 2020, the Company entered into a Term Credit Agreement (“Term Credit Agreement”) with certain institutional lenders that provides for a senior unsecured term loan facility in an aggregate principal amount of $400.0 million (the “Term Loan Facility”). The Term Loan Facility matures on January 24, 2023 with quarterly installments (commencing with the first full fiscal quarter ended after January 24, 2020) equal to 1.25% of the original principal amount of the Term Loan Facility. The remaining outstanding principal of borrowings under the Term Loan Facility is due upon maturity on January 24, 2023. Borrowings under the Term Loan Facility may be voluntarily prepaid, in whole or in part, without penalty or premium. Borrowings repaid or prepaid under the Term Loan Facility may not be reborrowed. Borrowings under the Term Loan Facility bear interest at a rate equal to, at the Company’s option, (a) LIBOR, adjusted for customary statutory reserves, plus an applicable margin of 1.125% to 1.75% depending on our leverage ratio, or (b) an alternate base rate determined in accordance with the Term Credit Agreement, plus an applicable margin of 0.125% to 0.750% depending on the Company’s leverage ratio. Interest on the outstanding principal of borrowings is currently due monthly in arrears. As of January 24, 2020, the margin for LIBOR-based loans was 1.125% and the margin for alternate base rate loans was 0.125%. Among certain affirmative and negative covenants provided in the Term Credit Agreement, there is a financial covenant that requires the Company to maintain a leverage ratio, calculated as of the last day of each fiscal quarter, of consolidated total indebtedness to consolidated EBITDA.

The proceeds from the Term Loan Facility were used to (i) finance, in part, the acquisition of Shape and (ii) to pay fees and expenses incurred in connection with the acquisition of Shape and the related transactions. As of February 5, 2020, there was $400.0 million outstanding under the Term Loan Facility.

Revolving Credit Agreement

On January 31, 2020, the Company entered into a Revolving Credit Agreement (the “Revolving Credit Agreement”) that provides for a senior unsecured revolving credit facility in an aggregate principal amount of $350.0 million (the “Revolving Credit Facility”). The Company has the option to increase commitments under the Revolving Credit Facility from time to time, subject to certain conditions, by up to $150.0 million. The Revolving Credit Facility matures on January 31, 2025. The remaining outstanding principal of borrowings under the Revolving Credit Facility is due upon maturity on January 31, 2025. The Company has the option to request up to two extensions of the maturity date in each case for an additional period of one year. Borrowings under the Revolving Credit Facility bear interest at a rate equal to, at the Company’s option, (a) LIBOR, adjusted for customary statutory reserves, plus an applicable margin of 1.125% to 1.75% depending on our leverage ratio, or (b) an alternate base rate determined in accordance with the Revolving Credit Agreement, plus an applicable margin of 0.125% to 0.750% depending on our leverage ratio. The Revolving Credit Agreement also requires payment of a commitment fee calculated at a rate per annum of 0.125% to 0.300% depending on our leverage ratio on the undrawn portion of the Revolving Credit Facility. Among certain affirmative and negative covenants provided in the Revolving Credit Agreement, there is a financial covenant that requires the Company to maintain a leverage ratio, calculated as of the last day of each fiscal quarter, of consolidated total indebtedness to consolidated EBITDA. As of February 5, 2020, there were no outstanding borrowings under the Revolving Credit Facility.


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

The following discussion of our financial condition and results of operations contains forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934 and Section 27A of the Securities Act of 1933. These statements include, but are not limited to, statements about our plans, objectives, expectations, strategies, intentions or other characterizations of future events or circumstances and are generally identified by the words “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” and similar expressions. These forward-looking statements are based on current information and expectations and are subject to a number of risks and uncertainties. Our actual results could differ materially from those expressed or implied by these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those discussed in Part II, Item 1A. “Risk Factors” herein and in other documents we file from time to time with the Securities and Exchange Commission. We assume no obligation to revise or update any such forward-looking statements.

Overview

Our enterprise-grade application services are available as cloud-based, software-as-a-service, and ~~data in~~software-only solutions optimized for multi-cloud environments, ~~and data centers. Our products include hardware-based software, software-only solutions, cloud-based services and managed service offerings~~with modules that ~~accelerate, optimize, secure and improve application performance for all types~~can run independently, or as part of ~~deployment scenarios.~~an integrated solution on our high-performance appliances. We market and sell our products primarily through multiple indirect sales channels in the Americas (primarily the United States); Europe, the Middle East, and Africa (EMEA); and the Asia Pacific region (APAC). Enterprise customers (Fortune 1000 or Business Week Global 1000 companies) in the technology, telecommunications, financial services, transportation, education, manufacturing and ~~health care~~healthcare industries, along with government customers, continue to make up the largest percentage of our customer base.

Our management team monitors and analyzes a number of key performance indicators in order to manage our business and evaluate our financial and operating performance on a consolidated basis. Those indicators include:

•

Revenues. The majority of our revenues are derived from sales of our application delivery controller (ADC) products including our BIG-IP appliances and VIPRION chassis and related software modules and our software-only Virtual Editions; Local Traffic Manager (LTM), DNS Services (formerly Global Traffic Manager); Advanced Firewall Manager (AFM) and Policy Enforcement Manager (PEM), that leverage the unique performance characteristics of our hardware and software architecture; and products that incorporate acquired technology, including Application Security Manager (ASM) and Access Policy Manager (APM); and the WebSafe, MobileSafe, Secure Web Gateway and Silverline DDoS and Application security offerings which are sold to customers on a subscription basis. We also derive revenues from the sales of services including annual maintenance contracts, training and consulting services. We carefully monitor the sales mix of our revenues within each reporting period. We believe customer acceptance rates of our new products and feature enhancements are indicators of future trends. We also consider overall revenue concentration by customer and by geographic region as additional indicators of current and future trends.

~~Revenues.~~ The majority of our revenues are derived from sales of our application delivery controller (ADC) products including our BIG-IP appliances and high end VIPRION chassis and related software modules and our software-only Virtual Editions; Local Traffic Manager (LTM), DNS Services (formerly Global Traffic Manager); Advanced Firewall Manager (AFM) and Policy Enforcement Manager (PEM), that leverage the unique performance characteristics of our hardware and software architecture; and products that incorporate acquired technology, including Application Security Manager (ASM) and Access Policy Manager (APM); and the WebSafe, MobileSafe, Secure Web Gateway and Silverline DDoS and Application security offerings which are sold to customers on a subscription basis.

We carefully monitor the sales mix of our revenues within each reporting period. We believe customer acceptance rates of our new products and feature enhancements are indicators of future trends. We also consider overall revenue concentration by customer and by geographic region as additional indicators of current and future trends.

~~Cost of revenues and gross margins.~~ We strive to control our cost of revenues and thereby maintain our gross margins. Significant items impacting cost of revenues are hardware costs paid to our contract manufacturers, third-party software license fees, Silverline infrastructure, amortization of developed technology and personnel and overhead expenses. Our margins have remained relatively stable; however, factors such as sales price, product and services mix, inventory obsolescence, returns, component price increases and warranty costs could significantly impact our gross margins from quarter to quarter and represent significant indicators we monitor on a regular basis.

~~Operating expenses.~~ Operating expenses are substantially driven by personnel and related overhead expenses. Existing headcount and future hiring plans are the predominant factors in analyzing and forecasting future operating expense trends. Other significant operating expenses that we monitor include marketing and promotions, travel, professional fees, computer costs related to the development of new products and provision of services, facilities and depreciation expenses.

~~Liquidity and cash flows.~~ Our financial condition remains strong with significant cash and investments and no long term debt. The increase in cash and investments for the first three months of fiscal year 2019 was primarily due to cash provided by operating activities of $197.9 million, partially offset by $101.0 million of cash used to repurchase outstanding common stock under our stock repurchase program. Going forward, we believe the primary driver of cash flows will be net income from operations. Capital expenditures of $21.0 million for the first three months of fiscal year 2019 were primarily related to the expansion of our facilities to support our operations worldwide as well as investments in information technology infrastructure and equipment purchases to support our core business activities. We will continue to evaluate possible acquisitions of, or investments in businesses, products, or technologies that we believe are strategic, which may require the use of cash.

~~Balance sheet.~~ We view cash, short-term and long-term investments, deferred revenue, accounts receivable balances and days sales outstanding as important indicators of our financial health. Deferred revenues increased in the ~~first quarter of fiscal year 2019~~ primarily due to growth in the amount of annual maintenance contracts purchased on new products and maintenance renewal contracts related to our existing product installation base. Our days sales outstanding for the ~~first quarter of fiscal year 2019~~ ~~was 54.~~

Liquidity and cash flows. Our financial condition remains strong with significant cash and investments. The increase in cash and investments for the first three months of fiscal year 2020 was primarily due to cash provided by operating activities of $144.0 million. Going forward, we believe the primary driver of cash flows will be net income from operations. Capital expenditures of $22.3 million for the first three months of fiscal year 2020 were primarily related to the expansion of our facilities to support our operations worldwide as well as investments in information technology infrastructure and equipment purchases to support our core business activities. We will continue to evaluate possible acquisitions of, or investments in businesses, products, or technologies that we believe are strategic, which may require the use of cash.

Deferred revenues increased in the first quarter of fiscal year 2020 primarily due to growth in the amount of annual maintenance contracts purchased on new products and maintenance renewal contracts related to our existing product installation base. Our days sales outstanding at the end of the first quarter of fiscal year 2020 was 56. Days sales outstanding is calculated by dividing ending accounts receivable by revenue per day for a given quarter.

Summary of Critical Accounting Policies and Estimates

The preparation of our financial condition and results of operations requires us to make judgments and estimates that may have a significant impact upon our financial results. We believe that, of our significant accounting policies, the following require estimates and assumptions that require complex, subjective judgments by management, which can materially impact reported results: revenue recognition and accounting for ~~income taxes.~~business combinations.

We adopted the new revenue recognition accounting standard (ASC 606) effective October 1, 2018 on a modified retrospective basis. For more information, refer to the "Revenue Recognition" and "Recently Adopted Accounting Standards" sections of Note 1 and Note 2 - Revenue from Contracts with Customers. There were no ~~other~~ material changes to our critical accounting policies and estimates compared to the critical accounting policies and estimates described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Form 10-K for the fiscal year ended September 30, ~~2018.~~2019. Actual results may differ from these estimates under different assumptions or conditions.

Results of Operations

The following discussion and analysis should be read in conjunction with our consolidated financial statements, related notes and risk factors included elsewhere in this Quarterly Report on Form 10-Q.

Net revenues. Total net revenues increased ~~3.9%~~4.7% for the three months ended December 31, ~~2018~~2019, from the ~~same~~comparable period in the prior year. Overall revenue growth for the three months ended December 31, ~~2018,~~2019, was primarily due to increased software revenue including our subscription-based products and increased service revenues as a result of our increased installed base of products. International revenues represented ~~51.3%~~51.6% of total net revenues for the three months ended December 31, ~~2018~~2019, compared to ~~49.5%~~51.3% for the same period in the prior year. We expect international sales will continue to represent a significant portion of net revenues, although we cannot provide assurance that international revenues as a percentage of net revenues will remain at current levels.

Net product revenues ~~increased 2.9%~~remained relatively flat for the three months ended December 31, ~~2018,~~2019, from the ~~same period in the prior year. The increase in net product revenues for the three months ended December 31, 2018 was primarily due to an increase in software sales compared to the same~~comparable period in the prior year.

Net service revenues increased ~~4.7%~~8.0% for the three months ended December 31, ~~2018,~~2019, from the ~~same~~comparable period in the prior year. The increase in net service revenues was primarily due to increases in the purchase or renewal of maintenance contracts driven by additions to our installed base of products.

The following distributors of the Company's products accounted for more than 10% of total net revenue:

Other income, net. Other income, net consists primarily of interest income and foreign currency transaction gains and losses. The ~~increase~~decrease in other income, net for the three months ended December 31, ~~2018~~2019 was primarily due to ~~increased~~a decrease in interest income of $1.4 million from our investments ~~as well as foreign currency gains,~~ compared to the same period in the prior year.

Provision for income taxes. The effective tax rate was ~~20.8%~~22.8% and ~~38.7%~~20.8% for the three months ended December 31, ~~2018~~2019 and ~~2017,~~2018, respectively. The ~~decrease~~increase in the effective tax rate for the three months ended December 31, ~~2018 is primarily due to the impact of a further reduction in the U.S. federal income tax rate to 21% and the initial effective date of other U.S. tax reform provisions,~~2019 as compared to the three months ended December 31, ~~2017 which included one-time charges for~~2018 is primarily due to the ~~deemed repatriation of undistributed foreign earnings and a remeasurement of the Company’s net deferred~~ tax ~~assets.~~impact from stock-based compensation.

We record a valuation allowance to reduce our deferred tax assets to the amount we believe is more likely than not to be realized. In making these determinations we consider historical and projected taxable income, and ongoing prudent and feasible tax planning strategies in assessing the appropriateness of a valuation allowance. Our net deferred tax assets at December 31, ~~2018~~2019 and September 30, ~~2018~~2019 were ~~$22.7~~$29.1 million and ~~$33.4~~$27.4 million, respectively. The net deferred tax assets include valuation allowances of ~~$22.4~~$23.4 million and ~~$22.8~~$23.5 million as of December 31, ~~2018~~2019 and September 30, ~~2018,~~2019, respectively, which are primarily related to tax net operating losses incurred in certain foreign jurisdictions, and state tax carryforwards.

Our worldwide effective tax rate may fluctuate based on a number of factors, including variations in projected taxable income in the various geographic locations in which we operate, changes in the valuation of our net deferred tax assets, resolution of potential exposures, tax positions taken on tax returns filed in the various geographic locations in which we operate, and the introduction of new accounting standards or changes in tax laws or interpretations thereof in the various geographic locations in which we operate. We have recorded liabilities to address potential tax exposures related to business and income tax positions we have taken that could be challenged by taxing authorities. The ultimate resolution of these potential exposures may be greater or less than the liabilities recorded which could result in an adjustment to our future tax expense.

In accordance with SEC Staff Accounting Bulletin No. 118, the Company finalized the computations for the deemed repatriation of undistributed foreign earnings and did not record any adjustments to the provisional amounts previously recorded.

Liquidity and Capital Resources

Cash and cash equivalents, short-term investments and long-term investments totaled ~~$1,546.3~~$1,474.3 million as of December 31, ~~2018,~~2019, compared to ~~$1,450.6~~$1,330.7 million as of September 30, ~~2018,~~2019, representing an increase of ~~$95.7~~$143.6 million. The increase was primarily due to cash provided by operating activities of ~~$197.9~~$144.0 million for the three months ended December 31, ~~2018, which was partially offset by $101.0 million of cash used for the repurchase of outstanding common stock under our stock repurchase program.~~2019. Cash provided by operating activities for the first three months of fiscal year ~~2019~~2020 resulted from net income of ~~$130.9~~$98.5 million combined with changes in operating assets and liabilities, as adjusted for various non-cash items including stock-based compensation, deferred revenue, depreciation and amortization charges. Based on our current operating and capital expenditure forecasts, we believe that our existing cash and investment balances, together with cash generated from operations should be sufficient to meet our operating requirements for at least the next twelve months.

Cash used in investing activities was ~~$60.4~~$29.4 million for the three months ended December 31, ~~2018,~~2019, compared to cash used in investing activities of ~~$121.1~~$60.4 million for the same period in the prior year. Investing activities include purchases, sales and maturities of available-for-sale securities, business acquisitions and capital ~~expenditures and changes in restricted cash requirements.~~expenditures. The amount of cash used in investing activities for the three months ended December 31, ~~2018~~2019 was primarily the result of ~~the purchase of investments and~~ capital expenditures related to the build-out of our new corporate headquarters and the ~~expansion~~purchase of ~~our international facilities,~~investments, partially offset by the maturity and sale of investments.

Cash ~~used in~~provided by financing activities was ~~$82.1~~$21.0 million for the three months ended December 31, ~~2018,~~2019, compared to cash used in financing activities of ~~$130.1~~$82.1 million for the same period in the prior year. Our financing activities for the three months ended December 31, ~~2018~~2019 consisted of ~~cash required for the repurchase of outstanding common stock under our stock repurchase program of $101.0 million, partially offset by~~ cash received from the exercise of employee stock options and stock purchases under our employee stock purchase plan of ~~$18.9~~$21.0 million.

Obligations and Commitments

As of December 31, ~~2018,~~2019, our principal commitments consisted of obligations outstanding under operating leases. We lease our facilities under operating leases that expire at various dates through 2033. There have been no material changes in our principal lease commitments compared to those discussed in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the fiscal year ended September 30, ~~2018.~~2019.

We outsource the manufacturing of our pre-configured hardware platforms to contract manufacturers who assemble each product to our specifications. Our agreement with our largest contract manufacturer allows them to procure component inventory on our behalf based upon a rolling production forecast. We are contractually obligated to purchase the component inventory in accordance with the forecast, unless we give notice of order cancellation in advance of applicable lead times.

Recent Accounting Pronouncements

The anticipated impact of recent accounting pronouncements is discussed in Note 1 to the accompanying Notes to Consolidated Financial Statements of this Quarterly Report on Form 10-Q.


Item 3.	Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk. We maintain an investment portfolio of various holdings, types, and maturities. Our primary objective for holding fixed income securities is to achieve an appropriate investment return consistent with preserving principal and managing risk. At any time, a sharp rise in market interest rates could have a material adverse impact on the fair value of our fixed income investment portfolio. Conversely, declines in interest rates, including the impact from lower credit spreads, could have a material adverse impact on interest income for our investment portfolio. Our fixed income investments are held for purposes other than trading. Our fixed income investments were not leveraged as of December 31, ~~2018~~2019. We monitor our interest rate and credit risks, including our credit exposures to specific rating categories and to individual issuers. As of December 31, ~~2018~~2019, ~~15.7%~~25.7% of our fixed income securities balance consisted of U.S. government and U.S. government agency securities. We believe the overall credit quality of our portfolio is strong.

Foreign Currency Risk. The majority of our sales and expenses are denominated in U.S. dollars and as a result, we have not experienced significant foreign currency transaction gains and losses to date.

Management believes there have been no material changes to our quantitative and qualitative disclosures about market risk during the three month period ended December 31, ~~2018~~2019, compared to those discussed in our Annual Report on Form 10-K for the year ended September 30, ~~2018~~2019.


Item 4.	Controls and Procedures

Our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) are designed to ensure that required information is properly recorded, processed, summarized and reported within the required timeframe, as specified in the rules set forth by the SEC. Our disclosure controls and procedures are also designed to ensure that information required to be disclosed is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, ~~2018~~2019. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of December 31, ~~2018~~2019.

There were no other changes in our internal control over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f) of the Exchange Act) during the period covered by this quarterly report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
