On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to allowance for credit losses, returns reserve for expected cancellations, fair value of and/or evaluation for impairment of goodwill and intangibleother long-lived assets, capitalization of internally developed software, benefit period for deferred sales commission costs, stock-based compensation expense, incremental borrowing rate used to calculate operating lease liabilities, income and sales tax liabilities, fair value of convertible senior notes, litigation, and other contingencies. The Company bases its estimates on known facts and circumstances, historical experience, and various other assumptions. Actual results could differ from those estimates under different assumptions or conditions.

RECLASSIFICATIONS AND OTHER CHANGES
During the fourth quarter of fiscal 2020, the Company determined that presenting service revenue as revenue from the Company's core communication services would provide transparency and clarity to the users of the financial statements. As such, the Company reclassified certain revenue and cost of revenue on its condensed consolidated statement of operations for the three and six months ended JuneSeptember 30, 2019. The reclassifications did not have any impact on total revenue, consolidated net loss, or cash flows. Professional services revenue and cost of professional services revenue previously reported in service revenue and cost of service revenue are now reported in other revenue and cost of other revenue. Product revenue and cost of product revenue are also now reported in other revenue and cost of other revenue. The reclassifications did not have any impact on total revenue, consolidated net loss, or cash flows.

In addition, certain prior year amounts in the condensed consolidated statements of cash flows have been reclassified to conform with the current year presentation of allowance for credit losses.presentation.
RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS
In June 2016, the FASBFinancial Accounting Standards Board ("FASB") issued ASU 2016‑13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, furtheras amended, by ASU 2018-19 issued in November 2019, ASU 2019-04 issued in April 2019, ASU 2019-05 issued in May 2019, ASU 2019-10 issued in November 2019, and ASU 2019-11 issued in November 2019, which replaces the existing impairment model with a forward-looking expected loss method. Under this update, on initial recognition and at each reporting period, an entity is required to recognize an allowance that reflects the entity's current estimate of credit losses expected to be incurred over the life of the financial instrument. For trade receivables, loans, and other financial instruments, an entity is required to use a forward-looking expected loss model to recognize credit losses that are probable. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes result in more timely recognition of credit losses. These ASUs are effective for annual and interim periods beginning after December 15, 2019, which is fiscal 2021 for the Company. The Company adopted ASU 2016-13 on a modified retrospective basis as of April 1, 2020 through a cumulative-effect adjustment to the Company's beginning accumulated deficit balance; the impact of the adoption was not material to the Company's consolidated financial statements as creditstatements. Credit losses are not expected to be significant based on historical collection trends, the financial condition of the Company’s customers, and external market factors, including those related to the COVID-19 pandemic. The Company will continue to actively monitor the impact of the recent COVID-19 pandemic on expected credit losses.
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), which makes modifications to disclosure requirements on fair value measurements. The amendment is effective for public companies with fiscal years beginning after December 15, 2019, which is fiscal 2021 for the Company. The Company adopted ASU 2018-13 in the first quarter of fiscal 2021,on April 1, 2020, and the impact of the adoption was immaterial to the Company's consolidated financial statements.
In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal Use Software (Subtopic 350-40), which reduces complexity for the accounting for costs of implementing a cloud computing service arrangement. The amendment is effective for public companies with fiscal years beginning after December 15, 2019, which is fiscal 2021 for the Company; early adoption is permitted. The Company adopted this guidance on a prospective basis effective April 1, 2020. The adoption of this guidance did not have a material impact on the Company's consolidated financial statements.
RECENT ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED
In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740), which enhances and simplifies various aspects of the income tax accounting guidance, including requirements such as tax basis step-up in goodwill obtained in a transaction that is not a business combination, ownership changes in investments, and interim-period accounting for enacted changes in tax law. The amendment will be effective for public companies with fiscal years beginning after December 15, 2020, which is fiscal 2022 for the Company; early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements.
In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40), which simplifies accounting for convertible instruments by eliminating two of the three accounting models available for convertible debt instruments and convertible preferred stock. The guidance also addresses how convertible instruments are accounted for in the diluted earnings per share calculation. The guidance is effective for fiscal years beginning after December 15, 2021, which is fiscal 2023 for the Company; early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its consolidated financial statements.

Contract assets$26,549 $24,123 $2,426 
Deferred revenue$12,130 $8,224 $3,906 
The change in contract assets was primarily driven by the recognition of revenue that has not yet been billed, net of amounts billed during the period and reserve for current estimate of credit losses. The increase in deferred revenue was due to billings in advance of performance obligations being satisfied, net of revenue recognized for services rendered during the period. Revenue of $3.7$1.3 million and $5.0 million was recognized during the three and six months ended JuneSeptember 30, 2020, which was offset by additional deferrals duringwere included in the deferred revenue balance at the beginning of the period.
Remaining Performance Obligations
The Company's subscription terms typically range from one to five years. Contract revenue as of June 30, 2020 that has not yet been recognized as of September 30, 2020 was approximately $290.0$330 million from remaining performance obligations. This excludes contracts with an original expected length of one year or less. The Company expects to recognize revenue on most of the remaining performance obligations over the next 36 months.
Deferred Sales Commission Costs
Amortization of deferred sales commission costs was $6.7 million and $4.5 million for the three months ended September 30, 2020 and 2019, respectively, and $12.8 million and $8.7 million, for the six months ended September 30, 2020 and 2019, respectively.

Lease Assignment


In the fourth quarter of fiscal 2018, the Company entered into a 132-month lease agreement (the "Agreement") with CAP Phase I, a Delaware limited liability company (the "Landlord"), to rent approximately 162,000 square feet of office space in a new building in San Jose, California. The lease term began on January 1, 2019. On April 30, 2019, due to the Company's rapid growth and greater than anticipated future space needs, the Company entered into an assignment and assumption (the "Assignment") of the Agreement with the Landlord, and Roku Inc., a Delaware corporation ("Roku"), whereby the Company assigned to Roku the Agreement. Pursuant to the Assignment, the Company expects to be released from all of its obligations under the lease and related standby letter of credit by the end of the Company’s fiscal year ending March 31, 2022, or shortly thereafter. The Company also expects to receive the reimbursement of base rent and direct expenses from Roku by the end of the Company’s fiscal year ending March 31, 2022 in accordance with the Assignment.
The obligations related to the Agreement are not included in the right-of-use asset or lease liabilities as of JuneSeptember 30, 2020. The remaining obligations related to the Assignment of $6.9$4.8 million and the termination fee of $0.8 million are recorded in other accrued liabilities and other liabilities, non-current, respectively, in the Company's condensed consolidated balance sheet. The expected receivable of $6.9 million is recorded in other current assets in the Company's condensed consolidated balance sheet.
8. COMMITMENTS AND CONTINGENCIES
Other Commitments, Indemnifications, and Contingencies
From time to time, the Company receives inquiries from federal and various state and municipal taxing agencies with respect to the remittance of sales, use, telecommunications, excise, payroll, and income taxes. Several jurisdictions are currently conducting tax audits of the Company's records. The Company collects from its customers or has accrued for taxes that it believes are required to be remitted. The amounts that have been remitted have historically been within the accruals established by the Company. The Company adjusts its accrued taxes when facts relating to specific exposures warrant such adjustment. The Company continues to conduct periodic review of the taxability of certain of its services that may be subject to sales, use, telecommunications or other similar indirect taxes in certain jurisdictions. As of JuneSeptember 30, 2020 and March 31, 2020, the Company had accrued contingent indirect tax liabilities of $4.5 million.
Legal Proceedings
The Company, from time to time, may be involved in a variety of claims, lawsuits, investigations and other proceedings, including patent infringement claims, employment litigation, regulatory compliance matters and contractual disputes, that can arise in the normal course of the Company's operations. The Company accrues a liability when management believes information available prior to the issuance of the financial statements indicates it is probable a loss has been incurred as of the date of the financial statements and the amount of loss can be reasonably estimated. The Company adjusts its accruals to reflect the impact of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case. Legal costs are expensed as incurred.
As of JuneSeptember 30, 2020, the Company does not have any material provisions for any such lawsuits, claims and proceedings and believes it is not probable that a loss had been incurred. Litigation is inherently unpredictable and subject to significant uncertainties. While there can be no assurances that favorable final outcomes will be obtained, the Company believes it has valid defenses with respect to legal matters pending against it. Future litigation could be costly to defend, could impose significant burdens on employees and cause the diversion of management's

attention, and could upon resolution have a material adverse effect on the Company's business, results of operations, financial condition and cash flows.
9. CONVERTIBLE SENIOR NOTES AND CAPPED CALL
Convertible Senior Notes
In February 2019, the Company issued $287.5 million aggregate principal amount of 0.50% convertible senior notes (the "Initial Notes") due 2024 in a private placement, including the exercise in full of the initial purchasers' option to purchase additional notes. The Initial Notes are senior unsecured obligations of the Company and interest is payable semiannually in arrears on February 1 and August 1 of each year, beginning on August 1, 2019. The Initial Notes will mature on February 1, 2024, unless earlier repurchased, redeemed, or converted. The total net proceeds from the debt offering, after deducting initial purchase discounts, debt issuance costs, and costs of the capped call transactions described below, were approximately $245.8 million.
In November 2019, the Company issued an additional $75 million aggregate principal amount of 0.50% convertible senior notes (the "Additional Notes" and together with the Initial Notes, the "Notes") due 2024 in a registered offering under the same indenture as the Initial Notes.The total net proceeds from the Additional Notes, after deducting underwriting discounts, debt issuance costs, and costs of the capped call transactions described below, were approximately $64.6 million. The Additional Notes constitute a further issuance of, and form a single series with, the Company’s outstanding 0.50% convertible senior notes

Table of Contents




due 2024 issued in February 2019 in the aggregate principal amount of $287.5 million.Immediately after giving effect to the issuance of the Additional Notes, the Company has $362.5 million aggregate principal amount of convertible senior notes.
The Notes are senior unsecured obligations of the Company and interest is payable semiannually in arrears on February 1 and August 1 of each year, beginning on February 1, 2020. The Notes will mature on February 1, 2024, unless earlier repurchased, redeemed, or converted.
Each $1,000 principal amount of the Notes are initially convertible into 38.9484 shares of the Company’s common stock, par value $0.001, which is equivalent to an initial conversion price of approximately $25.68 per share. The conversion rate is subject to adjustment upon the occurrence of certain specified events but will not be adjusted for any accrued and unpaid interest. In addition, upon the occurrence of certain corporate events that occur prior to the maturity date or following the Company's issuance of a notice of redemption, in each case as described in the Indenture, the Company will, in certain circumstances, increase the conversion rate for a holder that elects to convert its Notes in connection with such a corporate event or during the relevant redemption period.
The Notes will be convertible at certain times and upon the occurrence of certain events in the future. Further, on or after October 1, 2023, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their Notes, regardless of the foregoing circumstances. Upon conversion, the Company will satisfy its conversion obligation by paying or delivering, as the case may be, cash, shares of common stock, or a combination of cash and shares of common stock, at the Company's election. The Company’s current intent is to settle the principal amount of the Notes in cash upon conversion. During the threesix months ended JuneSeptember 30, 2020, the conditions allowing holders of the Notes to convert were not met.
The Company may not redeem the Notes prior to February 4, 2022. On or after February 4, 2022, theCompany may redeem for cash all or part of the Notes, at the redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if the last reported sale price of the common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Company provides a redemption notice. If a fundamental change (as defined in the indenture governing the notes) occurs at any time, holders of Notes may require the Company to repurchase for cash all or any portion of their Notes at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.
The Notes are senior unsecured obligations and will rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the Notes, equal in right of payment with the Company’s existing and future liabilities that are not so subordinated, effectively junior in right of payment to any of the Company’s secured indebtedness to the extent of the value of the assets securing such indebtedness, and structurally junior to all indebtedness and other liabilities (including trade payables) of current or future subsidiaries of the Company.

Capped Call
In connection with the pricing of the Initial Notes and Additional Notes, the Company entered into privately negotiated capped call transactions ("Capped Calls") with certain counterparties. The Capped Calls each have an initial strike price of approximately $25.68 per share, subject to certain adjustments, which corresponds to the initial conversion price of the Notes. The Capped Calls have initial cap prices of $39.50 per share, subject to certain adjustments. The Capped Calls are expected to partially offset the potential dilution to the Company’s Common Stock upon any conversion of the Notes, with such offset subject to a cap based on the cap price. The Capped Calls cover, subject to anti-dilution adjustments, approximately 14.1 million shares of the Company’s Common Stock. The Capped Calls are subject to adjustment upon the occurrence of specified extraordinary events affecting the Company, including merger events, tender offers and announcement events. In addition, the Capped Calls are subject to certain specified additional disruption events that may give rise to a termination of the Capped Calls, including nationalization, insolvency or delisting, changes in law, failures to deliver, insolvency filings and hedging disruptions. For accounting purposes, the Capped Calls are separate transactions, and not part of the terms of the Notes. As these transactions meet certain accounting criteria, the Capped Calls are recorded in stockholders' equity and are not accounted for as derivatives. The cost of $33.7 million incurred to purchase the Capped Calls in connection with the Initial Notes and $9.3 million in connection with the Additional Notes were recorded as a reduction to additional paid-in capital and will not be remeasured.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q. As discussed in the section titled “Forward-Looking Statements,” the following discussion and analysis contains forward-looking statements that involve risks and uncertainties, as well as assumptions that, if they never materialize or prove incorrect, could cause our results to differ materially from those expressed or implied by such forward-looking statements. Factors that could cause or contribute to these differences include, but are not limited to, those discussed below and elsewhere in this report, particularly those set forth under the section entitled "Risk Factors" in our annual report on Form 10-K for the fiscal year ended March 31, 2020 as modified by those in Part II, Item 1A of thisour Quarterly Report for the three-month period ended June 30, 2020 on Form 10-Q under the heading "Risk Factors."
BUSINESS OVERVIEW
We are a leading software-as-a-service (“SaaS”("SaaS") provider of voice, video, chat, contact center, and enterprise-class APIapplication programming interfaces ("API") solutions powered by one global cloud communications platform. From our proprietary cloud technology platform, organizations across all their locations and employees have access to unified communications, team collaboration, video conferencing, contact center, data and analytics, communication APIs, and other services, enabling them to be more productive and responsive to their customers.
Our customers range from small businesses to large enterprises and their users are spread across more than 150 countries. In recent years, we have increased our up-market focus on the mid-market and enterprise customer categories.
We have a portfolio of cloud-based offerings that are subscription based, made available at different rates varying by the specific functionalities, services and number of users. We generate service revenue from communication services subscriptions and platform usage. We generate other revenues from the sales and rentals of office phones and other hardware equipment, and professional services. We define a “customer” as one or more legal entities to which we provide services pursuant to a single contractual arrangement. In some cases, we may have multiple billing relationships with a single customer (for example, where we establish separate billing accounts for a parent company and each of its subsidiaries).
Our flagship service is our 8x8 X Series, a next generation suite of unified communications as a service ("UCaaS") and contact center as a service ("CCaaS") solutions, which consist of service plans of increasing functionality

designated X1, X2, etc., through X8. With 8x8 X Series, we provide enterprise-grade voice, unified communications, video meetings, team collaboration, and contact center functionalities from a single platform. We also offer standalone SaaS services for contact center, video meetings, and enterprise communication APIs. Through our July 2019 acquisition of Wavecell Pte. Ltd., an Asia-based global communication platform as a service ("CPaaS") provider of SMS, messaging, voice and video APIs to enterprises, we expanded our API offerings both geographically and in scope.functionally. We expect to continue integrating these services into our platform, as we believe in the value of the collective solutions.
PriorAs of September 30, 2020, over 90% of our customer base has been migrated to the launch of 8x8 X Series in 2018, our customers subscribed to our legacy products. We are migrating these customers from our legacy solutions to our 8x8 X Series product suite,platform and we intend to acceleratemigrate the paceremaining customer base through the end of customer migrations inthe fiscal 2021.year. These migrations may require us to incur professional services and related engineering costs. While we may not be able to recover these costs from our customers, we believe that we will realize other benefits including reducing the number of platforms that we are required to support and improved customer retention.

We continued to show an increase in our average annualized service revenue per customer, which grew to $7,883$8,052 in the firstsecond quarter of fiscal 2021, compared with $7,069$7,957 in the same period of fiscal 2020, as we are selling more to mid-market and enterprise customers. Service revenue from mid-market and enterprise customers represented 45%46% of total service revenue and grew 48%29% over the prior year. We also increased the number of bundled deals where customers purchase our integrated communications and contact center solutions, which we have referred to as bundled deals; 55% of our new bookings greater than $12,000 of annualized recurring revenue were from customers that selected bundled UCaaS and CCaaS, as compared to 51% one year ago.solutions.
Our continued business focus is on achieving improved operating efficiencies while delivering revenue growth. In fiscal 2020, we continuedWe continue to make important investments in our products and technology platform, and focusedfocus on key areas of spend in our go-to-market strategy. Additionally, we lookedaim to drive efficiencies in our small business customer acquisition and operations, and are heavily focused on expanding our business upmarket with mid-market and enterprise customers. We believe that this approach andeffective execution will enable the Company to grow and capture market share, during this phase of industry disruption, in a cost-effective way and support the Company in pursuit of its path to profitability and operating cash flow improvement, which we will continue to execute throughout fiscal 2021.improvement.
In the remainder of fiscal 2021, we plan to continue making investments in activities to acquire more customers, including global expansion and investing in our direct marketing efforts, sales force, e-commerce, and outbound marketing efforts. We also intend to continue investing in our indirect channel programs to acquire more third-party selling agents to help sell our solutions, including investments in our value added resellers ("VARs") and master agent programs. Should these upfront investments not result in additional revenue from new or existing customers, including as result of adverse impacts from the COVID-19 pandemic, and/or these cost reduction and efficiency efforts do not result in meaningful savings, our operating results may be adversely impacted.
IMPACTS OF COVID-19
The full extent of the impact of the COVID-19 pandemic on our business, operations and financial results will depend on numerous evolving factors that we may not be able to accurately predict, including those set forth under the section entitled "Risk Factors" in our annual report on Form 10-K for the fiscal year ended March 31, 2020 as modified by the "Risk Factors" section of thisour Quarterly Report.Report on Form 10-Q for the three-month period ended June 30, 2020. In an effort to contain COVID-19 or slow its spread, governments around the world have enacted various measures, some of which have been subsequently rescinded, modified or modified,reinstated, including orders to close non-essential businesses, isolate residents to their homes, and practice social distancing. To protect the health and safety of our employees, our workforce continues to spend a significant amount of time working from home with many of our offices around the world remaining closed and travel being curtailed for our employees as well as our customers.customers as the number of COVID-19 cases continues to surge and retreat in various locations globally, and the availability and reliability of testing remains inconsistent. These restrictions have altered the ways we conduct sales activities and market to current and prospective customers and how we conduct our ongoing business operations, resulting in reductions in travel related expenses and, by some measures, has resulted in improved employee productivity in certain areas. Small business and mid-size customers have been more impacted by the COVID-19 pandemic than enterprise customers, which has necessitated greater flexibility and responsiveness to our customers evolving needs.Additionally, while our usage revenue from CPaaS grew year-over-year in the first quarter, we did have lower than expected CPaaS usage during the quarter as a result of COVID-related slowdown in APAC; however we observed positive trends toward the end of the quarter. While we anticipate that the global health crisis caused by COVID-19, including any resurgences, and the measures enacted to slow its spread will negatively impact certain

business activity across the globe, to date, it has not resulted in as significant a negative impact on our business, as initially anticipated. We continue to proactively and closely monitor the health of our customers and suppliers and other impacts of the pandemic to determine whether risks of loss or other negative impacts upon our business exist. The effects of COVID-19 have also been considered in management's judgments around credit loss impairments.
COMPONENTS OF RESULTS OF OPERATIONS
Service Revenue
Service revenue consists of communication services subscriptions, platform usage revenue, and related fees from our UCaaS, CCaaS, and CPaaS offerings. We plan to continue to drive our business to increase service revenue through a combination of increased sales and marketing efforts, geographic expansion of our customer base outside the United States, innovation in product and technology, and through strategic partnerships and other business development.
Other Revenue
Other revenue consists primarily of revenues from sales and rentals of IP telephones in conjunction with our cloud telephony service,, and revenues from non-recurring professional services, primarily in support of deployment of our solutions and/or platform. Other revenue is dependent on the number of customers who choose to purchase or rent an IP telephone in conjunction with our service instead of using the solution on their cell phone, computer, or other compatible device, and/or choose to engage our services for implementation and deployment of our cloud services.

We estimate our annual effective tax rate at the end of each quarter. In estimating the annual effective tax rate, we consider, among other things, annual pre-tax income, permanent tax differences, the geographic mix of pre-tax income and the application and interpretations of existing tax laws. We record the tax effect of certain discrete items, which are unusual or occur infrequently, in the interim period in which they occur, including changes in judgment about deferred tax valuation allowances. The determination of the effective tax rate reflects tax expense and benefit generated in certain domestic and foreign jurisdictions. However, jurisdictions with a year-to-date loss where no tax benefit can be recognized are excluded from the annual effective tax rate.
Liquidity and Capital Resources
As of JuneSeptember 30, 2020, we had $167.2$159.4 million of cash, cash equivalents, and investments. In addition, as of September 30, 2020, we had $19.0 million as restricted cash which includesincluding $8.6 million in support of letter of credits securing leases for office facilities and $10.4$6.9 million held in escrow for our acquisition of Wavecell in July 2019, pursuant to the terms of the acquisition agreement. During the three months ended September 30, 2020, $3.5 million of restricted cash was released, and the remaining amount of $6.9 million held in escrow for our acquisition of Wavecell is due to be released in January 2021. By comparison, at March 31, 2020, we had $186.9 million of cash, cash equivalents, and investments as well as $19.0 million as restricted cash.
On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") was passed into law, andwhich amended portions of relevant tax laws and provided relief to certain qualifying entities. In connection with the CARES Act, the Company elected to defer certain employer payroll taxes, which is expected to reduce cash usage by over $4 million throughout fiscal 2021. The amounts deferred will be remitted to tax authorities during the third quarter of fiscal 2022 and fiscal 2023, respectively, when they become due. Other jurisdictions around the world have also provided similar tax relief, which the Company has elected to receive, where applicable; these benefits have a lesser impact to our expected cash flows during fiscal 2021.

In June 2020, the Company offered its employees a limited opportunity to receive a portion of their cash salary in shares of the Company's common stock. Based on employee elected participation, we expect lower cash usage from payroll compensation of over $4 million during fiscal 2021. Currently, the Company does not expect to offer this program beyond fiscal 2021. In addition, for fiscal 2021, the Company's executives received performance share units in place of a cash bonus plan. The timing of bonus payments for all other eligible employees was changed to semi-annually (in the third and first quarter of each fiscal year) from quarterly as in prior fiscal years. 
We believe that our existing cash, cash equivalents, and investment balances, and our anticipated cash flows from operations will be sufficient to meet our working capital and expenditure requirements for the next 12 months.
Period-over-Period Changes
Net cash used in operating activities for the threesix months ended JuneSeptember 30, 2020 was $9.3$13.1 million, compared with $20.5$44.5 million forin the threesix months ended JuneSeptember 30, 2019. Cash used in operating activities has historically beenwas affected by:

CRITICAL ACCOUNTING POLICIES & ESTIMATES
The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosures of assets and liabilities. On an on-going basis, we evaluate our critical accounting policies and estimates. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
ThereWith the exception of changes described within Part I, Item 1, Note 2, "Summary of Significant Accounting Policies", due to the adoption of ASU 2016-03, there have been no significant changes during the three months ended JuneSeptember 30, 2020 to our critical accounting policies and estimates previously disclosed in our Form 10-K for the fiscal year ended March 31, 2020.

Cash equivalents and investments were invested primarily in money market funds, U.S. treasury, commercial paper, and corporate bonds. Our investment policy is focused on the preservation of capital and supporting our liquidity needs. Under the policy, we invest in highly rated securities, while limiting the amount of credit exposure to any one issuer other than the U.S. government. We do not invest in financial instruments for trading or speculative purposes, nor do we use leveraged financial instruments. We utilize external investment managers who adhere to the guidelines of our investment policy. A hypothetical 10% change in interest rates would not have a material impact on the value of our cash, cash equivalents, or available-for-sale investments.
The Company issued $362.5 million aggregate principal amount of convertible senior notes of which the estimated fair value as of JuneSeptember 30, 2020 was $326.3$336.7 million. The fair value of the convertible senior notes is subject to interest rate risk, market risk and other factors due to the conversion feature. The fair value of the convertible senior notes will generally increase as our common stock price increases and will generally decrease as our common stock price declines. The interest and market value changes affect the fair value of the convertible senior notes but do not impact our financial position, cash flows, or results of operations due to the fixed nature of the debt obligation. Additionally, we carry the convertible senior notes at face value less unamortized discount on our consolidated balance sheets, and we present the fair value for required disclosure purposes only.
Foreign Currency Exchange Risk
We have foreign currency risks related to our revenue and operating expenses denominated in currencies other than the U.S. dollar, primarily the British Pound, causing both our revenue and our operating results to be impacted by fluctuations in the exchange rates.
Gains or losses from the revaluation of certain cash balances, accounts receivable balances, and intercompany balances that are denominated in these currencies impact our net income (loss). A hypothetical decrease in all foreign currencies against the US dollar of 10% would not result in a material foreign currency loss on foreign-denominated balances at JuneSeptember 30, 2020. As

our foreign operations expand, our results may be more impacted by fluctuations in the exchange rates of the currencies in which we do business.
At this time, we do not, but we may in the future, enter into financial instruments to hedge our foreign currency exchange risk.
ITEM 4. CONTROLS AND PROCEDURES
Evaluation of Effectiveness of Disclosure Controls and Procedures
We maintain disclosure controls and procedures as defined in Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (Disclosure Controls) that are designed to ensure that information we are required to disclose in reports filed or submitted under the Securities and Exchange Act of 1934 is accumulated and communicated to management, including our principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure, and that such information is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.
As of the end of the period covered by this Quarterly Report on Form 10-Q, under the supervision of our Chief Executive Officer and our Chief Financial Officer, we evaluated the effectiveness of our Disclosure Controls. Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our Disclosure Controls were effective as of JuneSeptember 30, 2020.
Limitations on the Effectiveness of Controls
Our management, including the Chief Executive Officer and Chief Financial Officer, do not expect that our Disclosure Controls or internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected.

ITEM 1A. RISK FACTORS
Except as disclosed below, thereThere have been no material changes from the risk factors previously disclosed in our annual report on Form 10-K for the fiscal year ended March 31, 2020.
Failure to comply with laws2020 and contractual obligations related to data privacy and protection could have a material adverse effect on our business, financial condition and operating results.quarterly report on Form 10-Q for the three-month period ended June 30, 2020.
We process many types of data, including personal data in the course of our business. As such, we are subject to the data privacy and protection laws and regulations adopted by federal, state and foreign governmental agencies, including the European Union’s General Data Protection Regulation ("GDPR") and the California Consumer Privacy Act ("CCPA"). Data privacy and protection is highly regulated in many jurisdictions and may become the subject of additional regulation in the future. For example, lawmakers and regulators worldwide are considering proposals that would require companies, like us, that encrypt users' data to ensure access to such data by law enforcement authorities. Privacy laws restrict our processing of personal information provided to us by our customers as well as data we collect from our customers and employees. We strive to comply with all applicable laws, regulations, policies and legal obligations relating to privacy and data protection. However, if we fail to comply, we may be subject to fines, penalties and lawsuits, statutory damages at both the federal and state levels in the U.S., substantial fines and penalties under the European Union’s GDPR, class action lawsuits, and our reputation may suffer. We may also be required to make modifications to our data practices that could have an adverse impact on our business, including increasing our operating costs which may cause us to increase our prices making our services less competitive. 
While the United Kingdom enacted a Data Protection Act in May 2018 that substantially implements the GDPR and implemented statutory amendments to the Data Protection Act in 2019 that further aligned it with GDPR, the United Kingdom’s exit from the European Union has created regulatory uncertainty such as with respect to the cross-border transfer of data. Such uncertainty may adversely impact the operations of our U.K. subsidiary and add operational complexities that did not previously exist. In addition on July 16, 2020, the Court of Justice of the European Union invalidated the Privacy Shield program. The Privacy Shield program allowed transfers of EU personal data to the U.S. for participating companies consistent with European privacy requirements for transfer of such data to non-EU countries. The Court also raised concerns about transfer of personal data to the U.S. under standard contractual clauses but did not invalidate this transfer mechanism. We participate in the Privacy Shield Program and have intra-company standard contractual clauses so we are currently able to transfer consistent with EU privacy requirements despite the Court’s decision. The decision, however, has created uncertainty about data transfer to the U.S. and it is likely that European regulators will provide further guidance on the use of standard contractual clauses for data transfers to the U.S. consistent with the Court’s decision.
We are also subject to the privacy and data protection-related obligations in our contracts with our customers and other third parties. Any failure, or perceived failure, by us to comply with federal, state, or international laws, including laws and regulations regulating privacy, data or consumer protection, or to comply with our contractual obligations related to privacy, could result in proceedings or actions against us by governmental entities, contractual parties or others, which could result in significant liability to us, as well as harm our reputation. Additionally, third parties on which we rely enter into contracts to protect and safeguard our customers' data. Should such parties violate these agreements or suffer a breach, we could be subject to proceedings or actions against us by governmental entities, contractual parties or others, which could result in significant liability to us as well as harm to our reputation.
