USE OF ESTIMATES
The preparation of the condensed consolidated financial statements in conformity with accounting principles generally accepted in the United StatesGAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and equity, and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates its estimates, including, but not limited to, those related to bad debts,allowance for credit losses, returns reserve for expected cancellations, fair value of and/or evaluation for impairment of goodwill and intangible 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, stock-based compensation,fair value of convertible senior notes, litigation, and other contingencies.

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 months ended June 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.
CertainIn addition, certain prior year amounts in the statementcondensed consolidated statements of cash flows have been reclassified to conform with the current year presentation.
SIGNIFICANT ACCOUNTING POLICIES
The significant accounting policies used in preparationpresentation of these condensed consolidated financial statements are disclosed in our Annual Report on Form 10-Kallowance for the fiscal year ended March 31, 2019 filed with the SEC on May 21, 2019, and there have been no changes to the Company's significant accounting policies during the three and six months ended September 30, 2019 except for the accounting policies described below that were updated as a result of adopting Accounting Standards Update ("ASU") 2016-02, Leases. All amounts and disclosures set forth herein are in compliance with this standard.credit losses.
RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS
EffectiveIn June 2016, the FASB issued ASU 2016‑13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, further amended by ASU 2018-19 issued in November 2019, ASU 2019-04 issued in April 1, 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 No. 2016-02 (“ASU 2016-02”), Leases using the2016-13 on a modified retrospective transition approach utilizing the effective date as the date of initial application. ASU 2016-02 establishes a new lease accounting model for leases, which requires lessees to recognize right-of-use assets and lease liabilities on the balance sheet, but lease expense will be recognized on the income statement in a manner similar to previous requirements. Prior years presented have not been adjusted for ASU 2016-02 and continue to be reported in accordance with our historical accounting policy.
The new standard provides a number of optional practical expedients in transition. The Company has elected the package of practical expedients permitted under the new lease standard, which among other things, allows the carryforward of the historical lease classification. As a result, there was no impact to opening retained earnings. The new standard also provides a practical expedient for an entity’s ongoing accounting. The Company has elected such practical expedient to not separate lease and non-lease components for all leases. It also made an accounting policy election to not recognize right-of-use assets and lease liabilities on the balance sheet for leases with a term of 12 months or less and will recognize lease payments as an expense on a straight-line basis over the lease term.
The adoption of the new lease standard resulted in the recognition of right-of-use assets and lease liabilities of approximately $20.0 million and $21.4 million, respectively, for existing operating leases. The Company does not have significant finance lease right-of-use assets or liabilities. The adoption of the new lease standard did not have a material impact on the Company's accumulated deficit as of April 1, 2019. For additional information on leases and2020 through a cumulative-effect adjustment to the Company's beginning accumulated deficit balance; the impact of the new lease standard, referadoption was not material to Note 7.
RECENT ACCOUNTING PRONOUNCEMENTSthe Company's consolidated financial statements as 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 Financial Accounting Standards Board ("FASB")FASB issued ASU 2018-13, Fair Value Measurement (Topic(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. Early adoption2019, which is permitted. fiscal 2021 for the Company.

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. Early2019, which is fiscal 2021 for the Company; early adoption is permitted. The Company is currently assessing the impactadopted this guidance on a prospective basis effective April 1, 2020.

RECENT ACCOUNTING PRONOUNCEMENTS NOT YET ADOPTED
In June 2016, the FASB issued ASU 2016‑13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments, which changes the impairment model for most financial assets. The new model uses a forward‑looking expected loss method, which will generally result in earlier recognition of allowances for losses. In November 2018, the FASB issued ASU 2018‑19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, which clarifies that receivables arising from operating leases are not within the scope of Topic 326, Financial Instruments—Credit Losses. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases. In AprilDecember 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives2019-12, Income Taxes (Topic 740), which enhances and Hedging,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 Topic 825, Financial Instruments, which clarifies treatment of certain credit losses. In May 2019, the FASB issued ASU 2019-05, Financial Instruments — Credit Losses (Topic 326): Targeted Transition Relief, which permits an entity, upon adoption of ASU 2016-13, to irrevocably elect the fair value option (on an instrument-by-instrument basis)interim-period accounting for eligible financial assets measured at amortized cost basis. These ASUs areenacted changes in tax law. The amendment will be effective for annual and interim periodspublic companies with fiscal years beginning after December 15, 2019, and2020, which is fiscal 2022 for the Company; early adoption is permitted. The Company is currently assessing the impact of this pronouncement to its condensed consolidated financial statements.

3. REVENUE RECOGNITION
Revenue Recognition
The Company recognizes service revenue, mainly from subscription services to its cloud-based voice, call center, video, collaboration and communication APIs solutions using the five-step model as prescribed by ASC 606:
Identification of the contract, or contracts, with a customer;
Identification of the performance obligations in the contract;
Determination of the transaction price;
Allocation of the transaction price to the performance obligations in the contract; and
Recognition of revenue when or as the Company satisfies a performance obligation.
The Company identifies performance obligations in contracts with customers, which may include subscription services and related usage, product revenue and professional services. The transaction price is determined based on the amount the Company expects to be entitled to receive in exchange for transferring the promised services or products to the customer. The transaction price in the contract is allocated to each distinct performance obligation in an amount that represents the relative amount of consideration expected to be received in exchange for satisfying each performance obligation. Revenue is recognized when performance obligations are satisfied. Revenues are recorded based on the transaction price excluding amounts collected on behalf of third parties such as sales and telecommunication taxes, which are collected on behalf of and remitted to governmental authorities. The Company usually bills its customers on a monthly basis. Contracts typically range from annual to multi-year agreements with payment terms of net 30-days or less. The Company occasionally allows a 30-day period to cancel a subscription and return products shipped for a full refund.
Judgments and Estimates
The estimation of variable consideration for each performance obligation requires the Company to make subjective judgments. The Company has service-level agreements with customers warranting defined levels of uptime reliability and performance. Customers may get credits or refunds if the Company fails to meet such levels. If the services do not meet certain criteria, fees are subject to adjustment or refund representing a form of variable consideration. The Company may impose minimum revenue commitments ("MRC") on its customers at the inception of the contract. Thus, in estimating variable consideration for each of these performance obligations, the Company assesses both the probability of MRC occurring and the collectability of the MRC, of which both represent a form of variable consideration.
The Company enters into contracts with customers that regularly include promises to transfer multiple services and products, such as subscriptions, products, and professional services. For arrangements with multiple services, the Company evaluates whether the individual services qualify as distinct performance obligations. In its assessment of whether a service is a distinct performance obligation, the Company determines whether the customer can benefit from the service on its own or with other readily available resources, and whether the service is separately identifiable from other services in the contract. This evaluation requires the Company to assess the nature of each individual service offering and how the services are provided in the context of the contract, including whether the services are significantly integrated, highly interrelated, or significantly modify each other, which may require judgment based on the facts and circumstances of the contract.
When agreements involve multiple distinct performance obligations, the Company allocates arrangement consideration to all performance obligations at the inception of an arrangement based on the relative standalone selling prices ("SSP") of each performance obligation. Usage fees deemed to be variable consideration meet the allocation exception for variable consideration. Where the Company has standalone sales data for its performance obligations which are indicative of the price at which the Company sells a promised good or service separately to a customer, such data is used to establish SSP. In instances where standalone sales data is not available for a particular performance obligation, the Company estimates SSP by the use of observable market and cost-based inputs. The Company continues to review the factors used to establish list price and will adjust standalone selling price methodologies as necessary on a prospective basis.
Service Revenue
Service revenue from subscriptions to the Company's cloud-based technology platform is recognized over time on a ratable basis over the contractual subscription term beginning on the date that the platform is made available to the customer. Payments received in advance of subscription services being rendered are recorded as a deferred revenue. Usage fees for our UCaaS and CCaaS offerings, either bundled or not bundled, are recognized as

revenue when earned. Usage fees for our CPaaS offerings are typically invoiced monthly in arrears and recognized as revenues when earned. Professional services for configuration, system integration, optimization, customer training or education are primarily billed on a fixed-fee basis and are performed by the Company directly or, alternatively, customers may also choose to perform these services themselves or engage their own third-party service providers. Professional services revenue is recognized over time as the services are rendered.
When a contract with a customer is signed, the Company assesses whether collection of the fees under the arrangement is probable. The Company estimates the amount to reserve for uncollectible amounts based on the aging of the contract balance, current and historical customer trends, and communications with its customers. These reserves are recorded as operating expenses against the contract asset (Accounts Receivable). In the normal course of business, the Company records revenue reductions for customer credits.
Product Revenue
The Company recognizes product revenue for telephony equipment at a point in time, when transfer of control has occurred, which is generally upon shipment. Sales returns are recorded as a reduction to revenue estimated based on historical experience.
Contract Assets
Contract assets are recorded for those parts of the contract consideration not yet invoiced but for which the performance obligations are completed. The revenue is recognized when the customer receives services or equipment for a reduced consideration at the onset of an arrangement, for example, when the initial month's services or equipment are discounted. Contract assets are included in other current or non-current assets in the condensed consolidated balance sheets, depending on if their reduction will be recognized during the succeeding twelve-month period or beyond.
Deferred Revenue
Deferred revenues represent billings or payments received in advance of revenue recognition and is recognized upon transfer of control. Balances consist primarily of annual plan subscription services and professional and training services not yet provided as of the balance sheet date. Deferred revenues that will be recognized during the succeeding twelve-month period are recorded as current deferred revenues in the condensed consolidated balance sheets, with the remainder recorded as other non-current liabilities in the condensed consolidated balance sheets.
Costs to Obtain a Customer Contract
Sales commissions and related expenses are considered incremental and recoverable costs of acquiring customer contracts. These costs are capitalized as current or non-current assets and amortized on a straight-line basis over the anticipated benefit period, which is five years. The benefit period was estimated by taking into consideration the length of customer contracts, technology lifecycle, and other factors. This amortization expense is recorded in sales and marketing expense within the Company's condensed consolidated statement of operations.
Disaggregation of Revenue
The Company disaggregates its revenue by geographic region. See Note 13 for more information.

7. RIGHT-OF-USE ASSETS AND LEASES
Operating Leases
The Company primarily leases facilities for office and data center space under non-cancellable operating leases for its U.S. and international locations that expire at various dates through 2030. For leases with a term greater than 12 months, the Company recognizes a right-of-use asset and a lease liability based on the present value of lease payments over the lease term. Variable lease payments are not included in the lease payments to measure the lease liability and are expensed as incurred. The Company’s leases have remaining terms of one to eleven years and some of the leases include a Company option to extend the lease term for one to five years, or more, which if reasonably certain to exercise, the Company includes in the determination of lease payments. The lease agreements do not contain any material residual value guarantees or material restrictive covenants.
As most of the Company's leases do not provide a readily determinable implicit rate, the Company uses the incremental borrowing rate at lease commencement, which was determined using a portfolio approach, based on

the rate of interest that the Company would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. The Company uses the implicit rate when a rate is readily determinable. Operating lease expense is recognized on a straight-line basis over the lease term.
Leases with an initial term of 12 months or less are not recognized on the balance sheet and the expense for these short-term leases is recognized on a straight-line basis over the lease term. Common area maintenance fees (or CAMs) and other charges related to these leases continue to be expensed as incurred.

9. CONVERTIBLE SENIOR NOTES AND CAPPED CALL
Convertible Senior 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 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 isare 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 three and six months ended SeptemberJune 30, 2019,2020, 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, the Company 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 11.214.1 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 wasin 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 this Quarterly Report on Form 10-Q under the heading "Risk Factors."
BUSINESS OVERVIEW
We are a leading Software-as-a-Servicesoftware-as-a-service (“SaaS”) provider of voice, video, chat, contact center, and enterprise-class API solutions powered by one global cloud communications platform.

We generate productother revenues from the salesales and rentals of office phones and other hardware equipment.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

We have now begunare migrating these customers from theseour legacy solutions to our 8x8 X Series product suite, and we intend to accelerate the pace of customer migrations during the remainder of fiscal 2020 and intoin fiscal 2021. These migrations may require us to incur professional services costs thatand related engineering costs. While we may not be able to recover these costs from our customers.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.
SUMMARY AND OUTLOOK
Our secondIn the first quarter results illustrate the fundamental strength inof fiscal 2021, our cloud communicationstotal service revenue which for the quarter was $104.5 million, including revenue from our CPaaS offerings, and reflects growth of 28.5% year-over-year.grew 27.1% year-over-year to $114.2 million. We continued to show an increase in our average monthlyannualized service revenue per customer, ("ARPC"),which grew to $7,883 in the first quarter of fiscal 2021, compared with $7,069 in the same period of fiscal 2020, as we are selling more to mid-market and enterprise customers.
Since Service revenue from mid-market and enterprise customers represented 45% of total service revenue and grew 48% over the beginningprior year. We also increased the number of fiscal 2018,deals where customers purchase our integrated communications and contact center solutions, which we have de-emphasized profitabilityreferred to as a short-term corporate goalbundled deals; 55% of our new bookings greater than $12,000 of annualized recurring revenue were from customers that selected bundled UCaaS and have focused insteadCCaaS, as compared to 51% one year ago.
Our continued business focus is on making investments necessary to accelerateachieving improved operating efficiencies while delivering revenue growth. This decision was based,In fiscal 2020, we continued to make important investments in part,our products and technology platform, and focused on key areas of spend in our belief that the communications market is at an inflection pointgo-to-market strategy. Additionally, we looked to drive efficiencies in the shift of businesses from legacy on-premise solutions to cloud services.our small business customer acquisition and operations, and focused on expanding our business upmarket with mid-market and enterprise customers. We believe that this industry trendapproach and execution will continue in fiscal 2020 and beyond. Accordingly, we believe that it is inenable the Company's interestCompany to continue to invest in our business -- in particular, to further build our technology platform, add new service offerings, grow our international presence and operations, and expand our sales and marketing activities, particularly in the channel--in order to allow us to scale efficiently and capture market share during this phase of industry disruption.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.
WeIn the remainder of fiscal 2021, we plan to continue making significant investments in activities to acquire more customers. We plan to continuecustomers, 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 agents.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 this Quarterly Report. 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 or modified, 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. 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 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.

General and administrative expenses for the three months ended SeptemberJune 30, 20192020 increased slightly as compared to the same prior year period due to a $3.0 million increase in personnel and related costs, and a $2.2$3.8 million increase in stock-based compensation costs.expense, a $1.3 million higher allowance for credit losses recognized partially in response to external market factors and uncertainties in connection with the COVID-19 pandemic, a $1.3 million increase in legal and tax related costs, and a $0.7 million increase in employee and consulting related expenditures. These increases were partially offset by a $1.2 million decrease in salescontract termination costs.

For the three months ended SeptemberJune 30, 20192020 and 2018,June 30, 2019, we recorded income tax expense of $0.3$0.2 million and $0.1 million, respectively. For the six months ended September 30, 2019 and 2018, we recorded income tax expense of $0.4 million and $0.2 million, respectively. These taxes were related to state minimum taxes and income taxes from our foreign operations.
Ourrespectively, resulting in effective tax rate was -0.6% for eachrates of the three months ended September 30, 2019(0.5)% and 2018, and -0.5% and -0.6% for the six months ended September 30, 2019 and 2018,(0.4)%, respectively.
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 SeptemberJune 30, 2019,2020, we had $212.0$167.2 million of cash, cash equivalents, and investments. In addition, we had $19.0 million as restricted cash, which includes $8.6 million in support of letter of credits securing leases for office facilities, in California and New York, and $10.4 million held in escrow for our recent acquisition of Wavecell, in July 2019, pursuant to the terms of the acquisition agreement. By comparison, at March 31, 2019,2020, we had $346.5$186.9 million of cash, cash equivalents, and investments as well as a $8.1$19.0 million in deposit as restricted cash.
On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") was passed into law, and 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.
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.

Historically, the Company maintained all investments as short-term investments on its balance sheet, as the Company could liquidate these investments at any time and did not limit its liquidation of investments by contractual maturity date. Given the recent issuance of the convertible senior notes, and the associated increased cash, cash equivalents and investment balances, the Company expects to hold certain investments for at least 12 months from the reporting date and records these investments in long-term investments in alignment with the contractual maturity dates.
Period-over-Period Changes
Net cash used in operating activities for the sixthree months ended SeptemberJune 30, 20192020 was $44.5$9.3 million, compared with $4.6$20.5 million used in operating activities for the sixthree months ended SeptemberJune 30, 2018.2019. Cash used in operating activities has historically been affected by:
the amount of net income or loss;
the amount of non-cash expense items such as depreciation and amortization;
the amortization associated with deferred sales commissions, debt discount and issuance costs;
the expense associated with stock options and stock-based awards; and
changes in working capital accounts, particularly in the timing of collections from receivable and payments of obligations.obligations, such as commissions.
During the three months ended June 30, 2020, net cash used in operating activities was primarily related to the net loss of $41.9 million, net cash outflow from sales commissions of $7.0 million, which were partially offset by non-cash charges such as stock-based compensation expense of $22.8 million, depreciation and amortization of intangibles and capitalized software of $11.3 million, amortization of debt discount of $4.1 million, and operating lease expenses of $3.8 million.
Net cash used in investing activities was $59.9$11.9 million in the sixthree months ended SeptemberJune 30, 2019,2020, compared with $0.3$11.2 million used inprovided by investing activities in sixthree months ended SeptemberJune 30, 2018.2019. The cash used in investing activities during the sixthree months ended SeptemberJune 30, 20192020 was primarily related to $57.8 million used in the acquisition of Wavecell, a $0.9 million payment released from escrow held for MarianalQ acquisition in the first quarter of fiscal 2019, combined with purchases of $7.1$2.5 million of property and equipment, investments and capitalized internal software development costs of $14.3 million. These amounts were partially offset by $20.3$8.9 million, and $0.6 million of proceeds from sales and maturitiespurchase of investments, net of purchasesproceeds from maturities of investments.
Net cash provided byused in financing activities was $0.5$0.1 million in the sixthree months ended SeptemberJune 30, 2019,2020, compared with $2.0$1.4 million usedprovided by financing activities in the sixthree months ended SeptemberJune 30, 2018.

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.
There have been no significant changes during the three months ended SeptemberJune 30, 20192020 to our critical accounting policies and estimates previously disclosed in our Form 10-K for the fiscal year ended March 31, 2019, except for our adoption of ASU 2016-02 as discussed in Notes 2 and 7 of the Notes to the Unaudited Condensed Consolidated Financial Statements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Interest Rate Fluctuation Risk
The primary objective of our investment activities is to preserve principal while maximizing income without significantly increasing risk. Some of the securities in which we invest may be subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. To minimize this risk, we may maintain our portfolio ofWe had cash, cash equivalents, and investments totaling $167.2 million as of short durationsJune 30, 2020. Cash equivalents and investments were invested primarily in a variety of securities, including commercial paper, money market funds, debtU.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, and certificateswhile limiting the amount of deposit.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.
AsThe Company issued $362.5 million aggregate principal amount of September 30, 2019, we had $222.4 million outstanding on our 0.50% convertible senior notes due 2024.of which the estimated fair value as of June 30, 2020 was $326.3 million. The valuesfair value of the Notes are exposedconvertible senior notes is subject to interest rate risk. Generally,risk, market risk and other factors due to the conversion feature. The fair market value of our fixed interest rate Notes will increase as interest rates fall and decrease as interest rates rise. In addition, the fair market value of the Notes is affected by our stock price. The fair market value of the Notesconvertible senior notes will generally increase as our common stock price increases and will generally decrease as our common stock price declines in value. However,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 Notesconvertible senior notes at face value less unamortized discount on our consolidated balance sheet,sheets, and we present the fair value for required disclosure purposes only.
We do not believe that a hypothetical 10% change in interest rates would have a material impact on our interest income or expenses, convertible senior notes, or financial statements for any periods presented.
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 translationrevaluation of certain cash balances, accounts receivable balances, and intercompany balances that are denominated in these currencies impact our other comprehensive income.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 SeptemberJune 30, 2019.2020. 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 SeptemberJune 30, 2019.2020.
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.

PART II --II. OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
The information set forth in Note 8, “Legal Proceedings” of Notes to Unaudited Condensed Consolidated Financial Statements under ITEM 1. FINANCIAL STATEMENTS of PART I is incorporated by reference in response to this item.
ITEM 1A. RISK FACTORS
ThereExcept as disclosed below, there 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, 20192020.
Failure to comply with laws and contractual obligations related to data privacy and protection could have a material adverse effect on our business, financial condition and operating results.
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 quarterly reportreputation may suffer. We may also be required to make modifications to our data practices that could have an adverse impact on Form 10-Qour 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 quarterly period ended June 30, 2019.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.
ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
On July 17, 2019, we issued 2,628,761 shares of our common stock in connection with the purchase of all of the issued and outstanding capital stock held by shareholders of Wavecell Pte.
