Statements that include the words “expect,” “intend,” “plan,” “believe,” “project,” “forecast,” “estimate,” “may,” “should,” “anticipate” and similar statements of a future or forward-looking nature identify forward-looking statements for purposes of the federal securities laws or otherwise.
Forward-looking statements address matters that involve risks and uncertainties. Accordingly, there are or will be important factors that could cause our actual results to differ materially from those indicated in these statements. These factors include the information set forth in Part 1, Item 1A, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019 and Part II, Item 1A, of this Quarterly Report, which we encourage you to carefully read, and include the following:
the effects of the COVID-19 pandemic have materially affected how we, our clients and business partners are operating, and the duration and extent to which it will impact our future results of operations and overall financial performance remains uncertain;
adverse economic conditions may harm our business;
our quarterly and annual results may fluctuate significantly, including as a result of the timing and success of new product and feature introductions by us, may not fully reflect the underlying performance of our business and may result in decreases in the price of our common stock;
if we are unable to attract new clients or sell additional services and functionality to our existing clients, our revenue and revenue growth will be harmed;
our recent rapid growth may not be indicative of our future growth, and even if we continue to grow rapidly, we may fail to manage our growth effectively;
failure to adequately retain and expand our sales force will impede our growth;
if we fail to manage our technical operations infrastructure, our existing clients may experience service outages, our new clients may experience delays in the deployment of our solution and we could be subject to, among other things, claims for credits or damages;
our growth depends in part on the success of our strategic relationships with third parties and our failure to successfully maintain, grow and manage these relationships could harm our business;
we have established, and are continuing to increase, our network of master agents and resellers to sell our solution; our failure to effectively develop, manage, and maintain this network could materially harm our revenues;
security breaches and improper access to or disclosure of our data or our clients’ data, or other cyber attacks on our systems, could result in litigation and regulatory risk, harm our reputation and our business;
the markets in which we participate involve numerous competitors and are highly competitive, and if we do not compete effectively, our operating results could be harmed;
if our existing clients terminate their subscriptions or reduce their subscriptions and related usage, our revenues and gross margins will be harmed and we will be required to spend more money to grow our client base;
we sell our solution to larger organizations that require longer sales and implementation cycles and often demand more configuration and integration services or customized features and functions that we may not offer, any of which could delay or prevent these sales and harm our growth rates, business and operating results;
because a significant percentage of our revenue is derived from existing clients, downturns or upturns in new sales will not be immediately reflected in our operating results and may be difficult to discern;
we rely on third-party telecommunications and internet service providers to provide our clients and their customers with telecommunication services and connectivity to our cloud contact center software and any

Table of Contents
failure by these service providers to provide reliable services could cause us to lose clients and subject us to claims for credits or damages, among other things;
we have a history of losses and we may be unable to achieve or sustain profitability;
the contact center software solutions market is subject to rapid technological change, and we must develop and sell incremental and new products in order to maintain and grow our business;
we may not be able to secure additional financing on favorable terms, or at all, to meet our future capital needs;
we may acquire other companies or technologies or be the target of strategic transactions, which could divert our management’s attention, result in additional dilution to our stockholders and otherwise disrupt our operations and harm our operating results;
failure to comply with laws and regulations could harm our business and our reputation; and
we may not have sufficient cash to service our convertible senior notes and repay such notes, if required.
The foregoing factors should not be construed as exhaustive and should be read together with the other cautionary statements included in this report. If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, our actual results may differ materially from what we anticipate. You should not place undue reliance on our forward-looking statements. Any forward-looking statements you read in this report reflect our views only as of the date of this report with respect to future events and are subject to these and other risks, uncertainties and assumptions relating to our operations, results of operations, growth strategy and liquidity. We undertake no obligation to update any forward-looking statements made in this report to reflect events or circumstances after the date of this report or to reflect new information or the occurrence of unanticipated events, except as required by law.

Notes to Condensed Consolidated Financial Statements (Unaudited)
1. Description of Business and Summary of Significant Accounting Policies
Five9, Inc. and its wholly-owned subsidiaries (the “Company”) is a provider of cloud software for contact centers. The Company was incorporated in Delaware in 2001 and is headquartered in San Ramon, California. The Company has offices in Europe and Asia, which primarily provide research, development, sales, marketing, and client support services.
Basis of Presentation
The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. All intercompany transactions and balances have been eliminated in consolidation.
Certain prior period amounts included in the condensed consolidated financial statements have been reclassified to conform to the current period presentation.
Use of Estimates
The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The significant estimates made by management affect revenue and related reserves. Management periodically evaluates such estimates and they are adjusted prospectively based upon such periodic evaluation. Actual results could differ from those estimates.
Significant Accounting Policies
The Company’s significant accounting policies are disclosed in its Annual Report on Form 10-K for the year ended December 31, 2019.
Recently Adopted Accounting Pronouncements
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires measurement and recognition of expected credit losses for financial assets held at amortized cost, including trade receivables. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss model that requires the forward-looking information to calculate credit loss estimates. 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 will result in more timely recognition of credit losses. The Company adopted ASU 2016-13 using the modified retrospective method on January 1, 2020. The adoption of ASU 2016-13 did not have a material impact on the Company’s consolidated financial position, operating results or cash flows. See Notes 3 and 4 for further information on the impact of this adoption.
Recent Accounting Pronouncements Not Yet Effective
In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which amends its guidance to simplify the accounting for income taxes by, among other provisions, removing exceptions to certain general principles in Topic 740, Income Taxes. The standard will be effective for the Company beginning in the first quarter of 2021, with early adoption permitted.

Table of Contents
The Company is currently evaluating the impact that the adoption of ASU 2019-12 will have on its consolidated financial statements.
The Company has reviewed or is in the process of evaluating all other issued, but not yet effective, accounting pronouncements and does not believe the future adoption of any such accounting pronouncements will cause a material impact on its consolidated financial position, operating results or cash flows.
2. Revenue
Contract Balances
The following table provides information about accounts receivable, net, deferred contract acquisition costs, contract assets and contract liabilities from contracts with customers (in thousands):
March 31, 2020December 31, 2019
Accounts receivable, net$39,972  $37,655  
Deferred contract acquisition costs:
Current$14,317  $13,014  
Non-current34,047  30,655  
Total deferred contract acquisition costs$48,364  $43,669  
Contract assets and contract liabilities:
Contract assets (included in prepaid expenses and other current assets)$623  $825  
Contract liabilities (deferred revenue) 25,632  24,681  
Contract liabilities (deferred revenue) (included in other long-term liabilities)3,978  1,550  
Net contract assets (liabilities)$(28,987) $(25,406) 
The Company receives payments from customers based upon billing cycles. Invoice payment terms are usually 30 days or less. Accounts receivable are recorded when the right to consideration becomes unconditional.
Deferred contract acquisition costs are recorded when incurred and are amortized over a customer benefit period of five years.
The Company’s contract assets consist of unbilled amounts typically resulting from professional services revenue recognition when it exceeds the total amounts billed to the customer. The Company’s contract liabilities consist of advance payments and billings in excess of revenue recognized.
In the three months ended March 31, 2020, the Company recognized revenue of $16.0 million related to its contract liabilities at December 31, 2019.
Remaining Performance Obligations
As of March 31, 2020, the aggregate amount of the total transaction price allocated in contracts with original duration of greater than one year to the remaining performance obligations was $154.1 million. The Company expects to recognize revenue on approximately four-fifths of the remaining performance obligation over the next 24 months, with the balance recognized thereafter. The Company has elected the optional exemption, which allows for the exclusion of the amounts for remaining performance obligations that are part of contracts with an original expected duration of one year or less. Such remaining performance obligations represent unsatisfied or partially unsatisfied performance obligations pursuant to ASC 606.

Although the Company had certain available-for-sale debt securities in an unrealized loss position as of March 31, 2020, no impairment loss was recorded since it did not intend to sell them, did not anticipate a need to sell them, and the decline in fair value was not due to any credit-related factors which it is now required to assess upon adoption of ASU 2016-13.
The contractual maturities of the Company’s marketable investments as of March 31, 2020 and December 31, 2019 were less than one year.

Table of Contents
Fair Value Measurements
The Company carries cash equivalents and marketable investments at fair value. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:
Level 1 — Observable inputs, which include unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2 — Observable inputs other than Level 1 inputs, such as quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3 — Unobservable inputs that are supported by little or no market activity and that are based on management’s assumptions, including fair value measurements determined by using pricing models, discounted cash flow methodologies or similar techniques.
The Company determined the fair value of its Level 1 financial instruments, which are traded in active markets, using quoted market prices for identical instruments.
Marketable investments classified within Level 2 of the fair value hierarchy are valued based on other observable inputs, including broker or dealer quotations or alternative pricing sources. When quoted prices in active markets for identical assets or liabilities are not available, the Company relies on non-binding quotes from its investment managers, which are based on proprietary valuation models of independent pricing services. These models generally use inputs such as observable market data, quoted market prices for similar instruments, historical pricing trends of a security as relative to its peers. To validate the fair value determination provided by its investment managers, the Company reviews the pricing movement in the context of overall market trends and trading information from its investment managers. The Company performs routine procedures such as comparing prices obtained from independent source to ensure that appropriate fair values are recorded.

As of March 31, 2020 and December 31, 2019, the estimated fair value of the Company’s outstanding 0.125% convertible senior notes due 2023 was $493.2 million and $437.0 million, respectively. The fair value was determined based on the quoted price of the convertible senior notes in an inactive market on the last trading day of the reporting period and has been classified as Level 2 in the fair value hierarchy. See Note 6 for further information on the Company’s 0.125% convertible senior notes due 2023.
There were no assets or liabilities measured at fair value on a non-recurring basis as of March 31, 2020 and December 31, 2019.
The Company’s other financial instruments’ fair value, including accounts receivable, accounts payable and other current liabilities, approximate its carrying value due to the relatively short maturity of those instruments. The carrying amounts of the Company’s finance leases approximate their fair value, which is the present value of expected future cash payments based on assumptions about current interest rates and the creditworthiness of the Company.

Table of Contents
The Company's adoption of ASU 2016-13 on January 1, 2020 required it to shift from an incurred loss impairment model to an expected credit loss model which requires it to consider historical loss rates and expectations of forward-looking losses to estimate its allowance for doubtful accounts on its trade accounts receivables, unbilled accounts receivables and contract assets. The adoption of this new standard resulted in an increase to the allowance for doubtful accounts reserve of $233 thousand during the three months ended March 31, 2020. The following table presents the change in the allowance for doubtful accounts, including consideration of expected credit losses, for the three months ended March 31, 2020 (in thousands):

6. Debt
0.125% Convertible Senior Notes and Capped Call
In May 2018, the Company issued $258.8 million aggregate principal amount of 0.125% convertible senior notes (“Notes”) due May 1, 2023 in a private offering. The Notes are the Company’s senior unsecured obligations and bear interest at a fixed rate of 0.125% per annum, payable semiannually in arrears on May 1 and November 1 of each year, beginning on November 1, 2018. The total net proceeds from the offering, after deducting initial purchase discounts and estimated debt issuance costs, were approximately $250.8 million.
Each $1,000 principal amount of the Notes is initially convertible into 24.4978 shares of the Company’s common stock (the “Conversion Option”), which is equivalent to an initial conversion price of approximately $40.82 per share of common stock, subject to adjustment upon the occurrence of specified events. The Notes are convertible, in multiples of $1,000 principal amount, at the option of the holders at any time prior to the close of business on the business day immediately preceding November 1, 2022, only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ended on September 30, 2018 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any five consecutive trading day period (the “Measurement Period”) in which the trading price (as defined in the indenture governing the Notes) per $1,000 principal amount of Notes for each trading day of the Measurement Period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate in effect on each

14

Table of Contents
such trading day; (3) if the Company calls any or all of the Notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. On or after November 1, 2022 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, in multiples of $1,000 principal amount, at the option of the holder regardless of the foregoing circumstances. 
Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election. If the Company undergoes a fundamental change (as defined in the indenture governing the Notes), subject to certain conditions, holders may require the Company to repurchase for cash all or any portion of their Notes, in principal amounts of $1,000 or a multiple thereof, at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase date. In addition, following certain corporate events that occur prior to the maturity date or if the Company issues a notice of redemption, it will, under certain circumstances, increase the conversion rate for holders who elect to convert their Notes in connection with such corporate event or during the relevant redemption period.
During the three months ended March 31, 2020, one of the conversion features of the Notes was triggered as the last reported sale price of the Company’s common stock was greater than $53.07 per share, which represents 130% of the initial conversion price of $40.82 per share, for at least 20 trading days in the period of 30 consecutive trading days ended on March 31, 2020 (the last trading day of the calendar quarter), and therefore, the Notes are convertible, in multiples of $1,000 principal amount, at the option of the Notes holders from April 1, 2020 to June 30, 2020. Whether the Notes will be convertible after June 30, 2020 will depend on the continued satisfaction of this condition or other conversion conditions in the future. The Company received elections to convert a limited number of Notes in the first quarter of 2020. The Company elected to satisfy one election through the payment of cash for an immaterial amount to such Note holder during the first quarter of 2020 and expects to satisfy the remaining elections during the second quarter of 2020 in cash. The Company has the option to settle any future election conversion notices in cash, shares, or a combination of cash and shares.
The Company may not redeem the Notes prior to May 5, 2021. The Company may redeem for cash all or any portion of the Notes, at its option, on or after May 5, 2021 if the last reported sale price of its 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 not more than two trading days immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. No sinking fund is provided for the Notes.
The Notes are the Company’s 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 to any of the Company’s unsecured indebtedness that is 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 the Company’s subsidiaries.
In accounting for the transaction, the Notes were separated into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated conversion feature. The carrying amount of the equity component representing the conversion option was $63.8 million and was determined by deducting the fair value of the liability component from the par value of the Notes. The equity component was recorded in additional paid-in-capital and is not re-measured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount (the “Debt Discount”) is being amortized to interest expense over the contractual term of the Notes at an effective interest rate of 6.39%.
In accounting for the debt issuance cost of $8.0 million related to the Notes, the Company allocated the total amount incurred to the liability and equity components of the Notes based on their relative values. Issuance costs attributable to the liability component were $6.0 million and are being amortized to interest expense using the effective interest method over the contractual term of the Notes. Issuance costs attributable to the equity component were netted with the equity component in additional paid-in-capital.

Total interest expense$3,401  $3,160  
In connection with the pricing of the Notes, the Company entered into privately negotiated capped call transactions (the “Capped Call Transactions”) with certain financial institutions. The Capped Call Transactions are expected generally to reduce the potential dilution to the Company’s common stock upon any conversion of the Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted Notes, as the case may be, with such reduction and/or offset subject to a cap based on the cap price. The initial cap price of the Capped Call Transactions is $62.80 per share, and is subject to certain adjustments under the terms of the Capped Call Transactions. The Capped Call Transactions cover, subject to anti-dilution adjustments, approximately 6.3 million shares of the Company’s common stock. For accounting purposes, the Capped Call Transactions are separate transactions, and not part of the terms of the Notes. As these transactions meet certain accounting criteria, the Capped Call Transactions are recorded in stockholders’ equity and are not accounted for as derivatives. The cost of $31.4 million incurred in connection with the Capped Call Transactions was recorded as a reduction to additional paid-in capital.

8. Net Loss Per Share
Basic net loss per share is calculated by dividing net loss by the weighted average number of shares of common stock outstanding during the period, and excludes any dilutive effects of employee stock-based awards. Diluted net loss per share is computed giving effect to all potentially dilutive shares of common stock, including common stock issuable upon exercise of stock options, vesting of restricted stock units and shares of common stock issuable upon conversion of convertible senior notes.
The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share data):

The Company uses the treasury stock method for calculating any potential dilutive effect of the conversion spread of its Notes. The conversion spread had a dilutive impact during the three months ended March 31, 2020, since the average market price of the Company’s common stock during the period exceeded the initial conversion price of $40.82 per share for the Notes. However, the potential shares of common stock issuable upon the conversion of the Notes were excluded from the calculation of diluted net loss per share because their effect would have been anti-dilutive.
9. Income Taxes
The provision for (benefit from) income taxes for the three months ended March 31, 2020 and 2019 was approximately $69 thousand and $(49) thousand, respectively. The provision for income taxes for the three months ended March 31, 2020 consisted primarily of foreign income taxes, state minimum taxes, as well as a benefit for a true-up to foreign income taxes. The benefit from income taxes for the three months ended March 31, 2019 consisted primarily of foreign income taxes, as well as a benefit for a true-up to foreign income taxes.
For the three months ended March 31, 2020 and 2019, the provision (benefit) for income taxes differed from the statutory amount primarily due to the Company realizing no benefit for current year losses due to maintaining a full valuation allowance against its domestic net deferred tax assets.
The realization of tax benefits of deferred tax assets is dependent upon future levels of taxable income, of an appropriate character, in the periods the items are expected to be deductible or taxable. Based on the available objective evidence, the Company does not believe it is more likely than not that the net deferred tax assets will be realizable. Accordingly, the Company has provided a full valuation allowance against the domestic net deferred tax assets as of March 31, 2020 and December 31, 2019. The Company intends to maintain the remaining valuation allowance until sufficient positive evidence exists to support a reversal of, or decrease in, the valuation allowance. During the three months ended March 31, 2020, there were no material changes to the total amount of unrecognized tax benefits.
10. Commitments and Contingencies
Commitments
The Company’s principal commitments consist of future payment obligations under its Notes, finance leases to finance data centers and other computer and networking equipment purchases, operating leases for office facilities, and agreements with third parties to provide co-location hosting, telecommunication usage and equipment maintenance services. These commitments as of December 31, 2019 are disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019, and did not change materially during the three months ended March 31, 2020, except for certain hosting and telecommunications agreements. As of March 31, 2020, the Company’s commitment under various hosting and telecommunications agreements totaled $8.1 million for terms ranging up to 36 months. These agreements require the Company to make monthly payments over the service term in exchange for certain network services.
As of March 31, 2020, $258.7 million of the Notes were outstanding. The Notes are due May 1, 2023. For more information concerning the Notes, see Note 6.

Legal Matters
The Company is involved in various legal and regulatory matters arising in the normal course of business. In management’s opinion, resolution of these matters is not expected to have a material impact on the Company’s consolidated results of operations, cash flows, or its financial position. However, due to the uncertain nature of legal matters, an unfavorable resolution of a matter could materially affect the Company’s future consolidated results of operations, cash flows or financial position in a particular period. The Company expenses legal fees as incurred.
Indemnification Agreements
In the ordinary course of business, the Company enters into agreements of varying scope and terms pursuant to which it agrees to indemnify clients, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, including breach of security, services to be provided by the Company or from intellectual property infringement claims made by third parties. In addition, the Company has entered into indemnification agreements with its directors, officers and certain employees that will require it, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. There are no claims that it is aware of that could have a material effect on the consolidated balance sheet, consolidated statement of operations and comprehensive loss, or consolidated statements of cash flows.

13. Acquisition of Whendu LLC

In November 2019, the Company acquired certain assets from Whendu, including its integration platform as a service ("iPaaS") platform, which the Company has determined to be an asset acquisition. The purchase price, including the Company’s transaction costs, was approximately $15.9 million, of which $15.4 million was allocated to the Whendu iPaaS platform and $0.5 million was allocated to an assembled workforce, on a relative fair value basis. The assets will be amortized on a straight-line basis over their useful lives of four and three years, respectively.

14. Subsequent Event

On April 1, 2020, the Company completed its acquisition of all of the outstanding shares of Virtual Observer, formerly known as Coordinated Systems, Inc., for cash consideration of $32 million, subject to adjustment, pursuant to a stock purchase agreement by and among the Company and Robert H. Hutcheon, David R. Brower and Daniel J. McGrail dated January 15, 2020. This acquisition, which is expected to be accounted for as a business combination, is intended to expand the Company's portfolio to include a cloud-based and integrated Workforce Optimization ("WFO") offering as a complement to its ongoing strategic partnerships with leading WFO providers.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
You should read the following discussion in conjunction with the condensed consolidated financial statements and notes thereto included elsewhere in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2019.
Overview
We are a pioneer and leading provider of intelligent cloud software for contact centers, facilitating more than six billion call minutes between our more than 2,000 clients and their customers per year. We believe we achieved this leadership position through our expertise and technology, which has empowered us to help organizations of all sizes transition from legacy on-premise contact center systems to our cloud solution. Our solution, which is comprised of our Virtual Contact Center, or VCC, cloud platform and applications, allows simultaneous management and optimization of customer interactions across voice, chat, email, web, social media and mobile channels, either directly or through our application programming interfaces, or APIs. Our VCC cloud platform matches each customer interaction with an appropriate agent resource and delivers relevant customer data to the agent in real-time through integrations with adjacent enterprise applications, such as customer relationship management, or CRM, software, to optimize the customer experience and improve agent productivity. Unlike legacy on-premise contact center systems, our solution requires minimal up-front investment, can be rapidly deployed and adjusted depending on our client’s requirements.
Since founding our business in 2001, we have focused exclusively on delivering cloud contact center software. We initially targeted smaller contact center opportunities with our telesales team and, over time, invested in expanding the breadth and depth of the functionality of our cloud platform to meet the evolving requirements of our clients. In 2009, we made a strategic decision to expand our market opportunity to include larger contact centers. This decision drove further investments in research and development and the establishment of our field sales team to meet the requirements of these larger contact centers. We believe this shift has helped us diversify our client base, while significantly enhancing our opportunity for future revenue growth. To complement these efforts, we have also focused on building client awareness and driving adoption of our solution through marketing activities, which include internet advertising, digital marketing campaigns, social media, trade shows, industry events, telemarketing and out of home campaigns.
We provide our solution through a SaaS business model with recurring subscriptions. We offer a comprehensive suite of applications delivered on our VCC cloud platform that are designed to enable our clients to manage and optimize interactions across inbound and outbound contact centers. We primarily generate revenue by selling subscriptions and related usage of our VCC cloud platform. We charge our clients monthly subscription fees for access to our solution, primarily based on the number of agent seats, as well as the specific functionalities and applications our clients deploy. We define agent seats as the maximum number of named agents allowed to concurrently access our solution. Our clients typically have more named agents than agent seats, and multiple named agents may use an agent seat, though not simultaneously. Substantially all of our clients purchase both subscriptions and related telephony usage from us. A small percentage of our clients subscribe to our platform but purchase telephony usage directly from wholesale telecommunications service providers. We do not sell telephony usage on a stand-alone basis to any client. The related usage fees are based on the volume of minutes for inbound and outbound interactions. We also offer bundled plans, generally for smaller deployments, where the client is charged a single monthly fixed fee per agent seat that includes both subscription and unlimited usage in the contiguous 48 states and, in some cases, Canada. We offer monthly, annual and multiple-year contracts to our clients, generally with 30 days’ notice required for reductions in the number of agent seats. Increases in the number of agent seats can be provisioned almost immediately. Our clients, therefore, are able to adjust the number of agent seats used to meet their changing contact center volume needs. Our larger clients typically choose annual contracts, which generally include an implementation and ramp period of several months. Fixed subscription fees, including bundled plans, are generally billed monthly in advance, while related usage fees are billed in arrears. For the three months ended March 31, 2020 and 2019, subscription and related usage fees accounted for 91% and 93%, respectively, of our revenue. The remainder was comprised of professional services revenue from the implementation and optimization of our solution.
Effect of COVID-19
In December 2019, a novel coronavirus disease known as COVID-19 was reported and on March 11, 2020, the World Health Organization, or WHO, characterized COVID-19 as a pandemic. This pandemic has resulted in a

Table of Contents
widespread health crisis that has significantly harmed the U.S. and global economies and financial markets, including those on which our common stock and our Notes trade, and may impact demand for our solutions.
In accordance with the various shelter-in-place and other social distancing orders of applicable government agencies, all of our employees have transitioned to work-from-home operations and we have canceled all business travel by our employees, which have changed how we operate our business. Our clients and business partners are also subject to various shelter-in-place and other social distancing orders, which have changed the way we interact with our clients and business partners.
Our financial results for the first quarter of 2020 were not materially impacted by COVID-19, primarily since many of the initial economic effects of the early stages of the COVID-19 pandemic resulting from the various shelter-in-place and other social distancing orders occurred towards the end of our first quarter. The severity and duration of the COVID-19 pandemic is uncertain and such uncertainty will likely continue in the near term and we will continue to actively monitor the situation taking into account the impact to our employees, customers, partners and suppliers. While there is considerable uncertainty, we believe that certain parts of our business will benefit, particularly over the longer term, from the need to enable work from home agents and to enhance business continuity planning. On the other hand, our smaller clients with less financial resources will likely see their business decline or cease altogether, and clients in certain industry verticals, such as travel and leisure, and consumer discretionary may reduce their number of agent seats. In addition, our clients in general, face uncertain and challenging macro economic conditions and may reduce the number of agent seats, delay purchasing decisions or payments, or impact their ability to pay.
See Part II, Item 1A. Risk Factors, for further discussion of the impact of the COVID-19 pandemic on our business and operations.
Key GAAP Operating Results
Our revenue increased to $95.1 million for the three months ended March 31, 2020, from $74.5 million for the three months ended March 31, 2019. Revenue growth has primarily been driven by our larger clients. For each of the three months ended March 31, 2020 and 2019, no single client accounted for more than 10% of our total revenue. As of March 31, 2020, we had over 2,000 clients across multiple industries. Our clients’ subscriptions generally range in size from fewer than 10 agent seats to approximately 3,500 agent seats. We had a net loss of $7.4 million in the three months ended March 31, 2020, compared to a net loss of $1.9 million in the three months ended March 31, 2019.
We have continued to make significant expenditures and investments, including in sales and marketing, research and development and infrastructure. We primarily evaluate the success of our business based on revenue growth and the efficiency and effectiveness of our investments. The growth of our business and our future success depend on many factors, including our ability to continue to expand our base of larger clients, grow revenue from our existing client base, innovate and expand internationally. While these areas represent significant opportunities for us, they also pose risks and challenges that we must successfully address in order to sustain the growth of our business and improve our operating results, including the impact of the COVID-19 pandemic. In order to pursue these opportunities, we anticipate that we will continue to expand our operations and headcount in the longer term, though at a tempered rate in the near term, in consideration of the impact of COVID-19 and the resulting macro economic environment.
Due to our continuing investments to grow our business, increase our sales and marketing efforts, pursue new opportunities, enhance our solution and build our technology, we expect our cost of revenue and operating expenses to increase in absolute dollars in future periods. However, we expect cost of revenue and certain operating expenses to fluctuate as a percentage of revenue in the near term taking into consideration the impact of COVID-19 and the macro economic environment.
Key Operating and Non-GAAP Financial Performance Metrics
In addition to measures of financial performance presented in our condensed consolidated financial statements, we monitor the key metrics set forth below to help us evaluate growth trends, establish budgets, measure the effectiveness of our sales and marketing efforts and assess operational efficiencies.

Table of Contents
Annual Dollar-Based Retention Rate
We believe that our Annual Dollar-Based Retention Rate provides insight into our ability to retain and grow revenue from our clients, and is a measure of the long-term value of our client relationships. Our Annual Dollar-Based Retention Rate is calculated by dividing our Retained Net Invoicing by our Retention Base Net Invoicing on a monthly basis, which we then average using the rates for the trailing twelve months for the period being presented. We define Retention Base Net Invoicing as recurring net invoicing from all clients in the comparable prior year period, and we define Retained Net Invoicing as recurring net invoicing from that same group of clients in the current period. We define recurring net invoicing as subscription and related usage revenue excluding the impact of service credits, reserves and deferrals. Historically, the difference between recurring net invoicing and our subscription and related usage revenue has been within 10%.
The following table shows our Annual Dollar-Based Retention Rate for the periods presented:
Twelve Months Ended
March 31, 2020March 31, 2019
Annual Dollar-Based Retention Rate103%107%
Our Dollar-Based Retention Rate decreased year over year primarily due to fluctuations caused by our larger clients coming onto the platform at different times and ramping at different rates.
Adjusted EBITDA
We monitor adjusted EBITDA, a non-GAAP financial measure, to analyze our financial results and believe that it is useful to investors, as a supplement to U.S. GAAP measures, in evaluating our ongoing operational performance and enhancing an overall understanding of our past financial performance. We believe that adjusted EBITDA helps illustrate underlying trends in our business that could otherwise be masked by the effect of the income or expenses that we exclude from adjusted EBITDA. Furthermore, we use this measure to establish budgets and operational goals for managing our business and evaluating our performance. We also believe that adjusted EBITDA provides an additional tool for investors to use in comparing our recurring core business operating results over multiple periods with other companies in our industry.
Adjusted EBITDA should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with U.S. GAAP, and our calculation of adjusted EBITDA may differ from that of other companies in our industry. We compensate for the inherent limitations associated with using adjusted EBITDA through disclosure of these limitations, presentation of our financial statements in accordance with U.S. GAAP and reconciliation of adjusted EBITDA to the most directly comparable U.S. GAAP measure, net loss. We calculate adjusted EBITDA as net loss before (1) depreciation and amortization, (2) stock-based compensation, (3) interest income, expense and other, (4) acquisition-related transaction costs, (5) provision for income taxes, and (6) other items that do not directly affect what we consider to be our core operating performance.

Key Components of Our Results of Operations
Revenue
Our revenue consists of subscription and related usage as well as professional services. We consider our subscription and related usage to be recurring revenue. This recurring revenue includes fixed subscription fees for the delivery and support of our VCC cloud platform, as well as related usage fees. The related usage fees are generally based on the volume of minutes for inbound and outbound client interactions. We also offer bundled plans, generally for smaller deployments, where the client is charged a single monthly fixed fee per agent seat that includes both subscription and unlimited usage in the contiguous 48 states and, in some cases, Canada. We offer monthly, annual and multiple-year contracts for our clients, generally with 30 days’ notice required for reductions in the number of agent seats. Increases in the number of agent seats can be provisioned almost immediately. Our clients, therefore, are able to adjust the number of agent seats used to meet their changing contact center volume needs. Our larger clients typically choose annual contracts, which generally include an implementation and ramp period of several months.
Fixed subscription fees, including plans with bundled usage, are generally billed monthly in advance, while variable usage fees are billed in arrears. Fixed subscription fees are recognized on a straight-line basis over the applicable term, which is predominantly the monthly contractual billing period. Support activities include technical assistance for our solution and upgrades and enhancements on a when and if available basis, which are not billed separately. Variable subscription related usage fees for non-bundled plans are billed in arrears based on client-specific per minute rate plans and are recognized as actual usage occurs. We generally require advance deposits from clients based on estimated usage. All fees, except usage deposits, are non-refundable.
In addition, we generate professional services revenue from assisting clients in implementing our solution and optimizing use. These services include application configuration, system integration and education and training services. Professional services are primarily billed on a fixed-fee basis and are typically performed by us directly. In limited cases, our clients choose to perform these services themselves or engage their own third-party service providers to perform such services. Professional services are recognized as the services are performed using the proportional performance method, with performance measured based on labor hours, provided all other criteria for revenue recognition are met.
Cost of Revenue
Our cost of revenue consists primarily of personnel costs, including stock-based compensation, fees that we pay to telecommunications providers for usage, USF contributions and other regulatory costs, depreciation and related expenses of the servers and equipment, costs to build out and maintain co-location data centers, allocated office and facility costs and amortization of acquired technology. Cost of revenue can fluctuate based on a number of factors, including the fees we pay to telecommunications providers, which vary depending on our clients’ usage of our VCC cloud platform, the timing of capital expenditures and related depreciation charges and changes in headcount. We expect to continue investing in our network infrastructure and operations and client support function to maintain high quality and availability of service, resulting in absolute dollar increases in cost of revenue. As our business grows, we expect to realize economies of scale in network infrastructure, personnel and client support.

Table of Contents
Operating Expenses
We classify our operating expenses as research and development, sales and marketing, and general and administrative expenses.
Research and Development.    Our research and development expenses consist primarily of salary and related expenses, including stock-based compensation, for personnel related to the development of improvements and expanded features for our services, as well as quality assurance, testing, product management and allocated overhead. We expense research and development expenses as they are incurred except for internal use software development costs that qualify for capitalization. We believe that continued investment in our solution is important for our future growth, and we expect our research and development expenses to increase in absolute dollars and as a percentage of revenue in the near term.
Sales and Marketing.    Sales and marketing expenses consist primarily of salaries and related expenses, including stock-based compensation, for personnel in sales and marketing, sales commissions, as well as advertising, marketing, corporate communications, travel costs and allocated overhead. We believe it is important to continue investing in sales and marketing to continue to generate revenue growth, and we expect sales and marketing expenses to increase in absolute dollars over the long term and fluctuate as a percentage of revenue as we continue to support our growth initiatives.
General and Administrative.    General and administrative expenses consist primarily of salary and related expenses, including stock-based compensation, for management, finance and accounting, legal, information systems and human resources personnel, professional fees, compliance costs, other corporate expenses and allocated overhead. We expect that general and administrative expenses will fluctuate in absolute dollars and as a percentage of revenue in the near term, due to among other things, the impact of COVID-19 and the resulting macro economic conditions, but to decline as a percentage of revenue over time.

The unfavorable change of $(0.8) million in other income (expense), net for the three months ended March 31, 2020 compared to the same period of 2019 was primarily due to lower interest income on our marketable investments.
Liquidity and Capital Resources
To date, we have financed our operations primarily through sales of our solution, lease facilities and net proceeds from our equity and debt financings, including the issuance of our 0.125% convertible senior notes in May

Table of Contents
2018. As of March 31, 2020, we had $322.9 million in working capital, which included $155.9 million in cash and cash equivalents and $170.4 million in marketable investments.
In May 2018, we issued $258.8 million aggregate principal amount of our 0.125% convertible senior notes, or Notes, due May 1, 2023 in a private offering. The Notes are our senior unsecured obligations and bear interest at a fixed rate of 0.125% per annum, payable semiannually in arrears on May 1 and November 1 of each year, beginning November 1, 2018. The total net proceeds from the offering, after deducting the initial purchasers’ discounts and estimated debt issuance costs, were approximately $250.8 million. For additional information regarding the Notes, see Note 6 to the condensed consolidated financial statements included in this report.
We believe our existing cash and cash equivalents will be sufficient to meet our working capital and capital expenditure needs for at least the next 12 months.  Our future capital requirements will depend on many factors including our growth rate, continuing market acceptance of our solution, client retention, our ability to gain new clients, the timing and extent of spending to support research and development efforts, the outcome of any pending or future litigation or other claims by third parties or governmental entities, the expansion of sales and marketing activities and personnel and the introduction of new and enhanced offerings, including the impact of the COVID-19 pandemic on these or other factors. We may also acquire or invest in complementary businesses, technologies and intellectual property rights, which may increase our future capital requirements, either to pay acquisition costs or to support our combined operations. We may raise additional equity or debt financing at any time. We may not be able to raise additional equity or debt financing on terms acceptable to us or at all, particularly if the COVID-19 pandemic continues to negatively impact stock and debt markets. If we are unable to raise additional capital when desired or required, our business, operating results, and financial condition would be harmed. In addition, if our operating performance during the next twelve months is below our expectations, our liquidity and ability to operate our business could be harmed.
If we raise additional funds by issuing equity or equity-linked securities, the ownership of our existing stockholders will be diluted. If we raise additional funds through the incurrence of additional indebtedness, we will be subject to increased debt service obligations and could also be subject to restrictive covenants and other operating restrictions that could harm our ability to conduct our business.
Cash Flows
The following table summarizes our cash flows for the periods presented (in thousands, except percentages):

Net increase in cash and cash equivalents$77,887  $11,580  $66,307  573 %
Cash Flows from Operating Activities
Cash provided by operating activities is primarily influenced by our personnel-related expenditures, data center and telecommunications carrier costs, office and facility related costs, USF contributions and other regulatory costs and the amount and timing of client payments. If we continue to improve our financial results, we expect net cash provided by operating activities to increase. Our largest source of operating cash inflows is cash collections from our clients for subscription and related usage services. Payments from clients for these services are typically received monthly.
Net cash provided by operating activities was $10.4 million during the three months ended March 31, 2020. Net cash provided by operating activities resulted from our net loss of $7.4 million adjusted for non-cash items of $24.1 million, primarily consisting of $13.8 million of stock-based compensation, $5.0 million of depreciation and amortization and $3.3 million of amortization of discount and issuance costs on our Notes, offset by use of cash for operating assets and liabilities of $6.2 million primarily due to the timing of cash payments to vendors and cash receipts from customers.
Net cash provided by operating activities was $11.2 million during the three months ended March 31, 2019. Net cash provided by operating activities resulted from our net loss of $1.9 million adjusted for non-cash items of

$15.3 million, primarily consisting of $8.7 million of stock-based compensation, $3.2 million of depreciation and amortization and $3.1 million of amortization of discount and issuance costs on our Notes, offset by use of cash for operating assets and liabilities of $2.2 million primarily due to the time of cash payments to vendors and cash receipts from customers.
Cash Flows from Investing Activities
Net cash provided by investing activities in the three months ended March 31, 2020 was comprised of $134.6 million related to cash proceeds from maturities of marketable investments, offset in part by $62.3 million related to purchases of marketable investments and $6.0 million in capital expenditures.
Net cash provided by investing activities in the three months ended March 31, 2019 was comprised of $39.5 million related to cash proceeds from maturities of marketable investments and $0.2 cash proceeds related to gain from the sale of convertible notes held for investment, offset in part by $34.4 million related to purchases of marketable investments and $4.0 million in capital expenditures.
Cash Flows from Financing Activities
Net cash provided by financing activities of $1.4 million in the three months ended March 31, 2020 related to cash proceeds of $2.6 million from exercise of stock options, offset in part by payments for finance leases of $1.2 million.
Net cash used in financing activities of $0.9 million in the three months ended March 31, 2019 related to payments for finance leases of $1.9 million, offset in part by cash proceeds of $1.0 million from exercises of stock options.
Critical Accounting Policies and Estimates
Our condensed consolidated financial statements are prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and related disclosures. On an ongoing basis, we evaluate our estimates and assumptions. Our actual results may differ from these estimates under different assumptions or conditions.
We believe our critical accounting policies involve the greatest degree of judgment and complexity and have the greatest potential impact on our condensed consolidated financial statements.
Revenue Recognition
Revenue is recognized when control of the promised services are transferred to customers, in an amount that reflects the consideration that we expect to receive in exchange for those services. We generate all of our revenue from contracts with customers. In contracts with multiple performance obligations, we identify each performance obligation and evaluate whether the performance obligations are distinct within the context of the contract at contract inception. Performance obligations that are not distinct at contract inception are combined. We allocate the transaction price to each distinct performance obligation proportionately based on the estimated standalone selling price for each performance obligation. We then look to how services are transferred to the customer in order to determine the timing of revenue recognition. Most services provided under our agreements result in the transfer of control over time.
Our revenue consists of subscription services and related usage as well as professional services. We charge clients subscription fees, usually billed on a monthly basis, for access to our VCC solution. The subscription fees are primarily based on the number of agent seats, as well as the specific VCC functionalities and applications deployed by the client. Agent seats are defined as the maximum number of named agents allowed to concurrently access our VCC cloud platform. Clients typically have more named agents than agent seats. Multiple named agents may use an agent seat, though not simultaneously. Substantially all of our clients purchase both subscriptions and related telephony usage. A small percentage of our clients subscribe to our platform but purchase telephony usage directly from a wholesale telecommunications service provider. We do not sell telephony usage on a stand-alone basis to any client. The related usage fees are based on the volume of minutes used for inbound and outbound client interactions. Revenue generated from telephony usage is presented in revenue and cost of sales on a gross basis, as we are the party that controls the service and are responsible for fulfilling the promise to provide the call service by diverting

Table of Contents
the calls to selected carriers. We also offer bundled plans, generally for smaller deployments, whereby the client is charged a single monthly fixed fee per agent seat that includes both subscription and unlimited usage in the contiguous 48 states and, in some cases, Canada. Professional services revenue is derived primarily from VCC implementations, including application configuration, system integration, optimization, education and training services. Clients are not permitted to take possession of our software.
We offer monthly, annual and multiple-year contracts to our clients, generally with 30 days’ notice required for reductions in the number of agent seats. Increases in the number of agent seats can be provisioned almost immediately. Our clients, therefore, are able to adjust the number of agent seats used to meet their changing contact center volume needs. Our larger clients typically choose annual contracts, which generally include an implementation and ramp period of several months. Fixed subscription fees, including bundled plans, are generally billed monthly in advance, while related usage fees are billed in arrears. Support activities include technical assistance for our solution and upgrades and enhancements to our VCC cloud platform on a when-and-if-available basis, which are not billed separately.
Professional services are primarily billed on a fixed-fee basis and are performed by us directly or, alternatively, clients may also choose to perform these services themselves or engage their own third-party service providers. Revenue for professional services is recognized over time, as services are performed.
The estimation of variable consideration for each performance obligation requires us to make subjective judgments. In the early stages of our larger contracts, in order to allocate the overall transaction fee on a relative stand-alone selling price basis to our multiple performance obligations, we estimate variable consideration to be included in the transaction fee to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. When services are included in the contract with the customer and are not sold at their stand-alone selling price, this requires us to estimate the number of seats the customer will use, especially during the initial ramp period of the contract, during which we bill under an ‘actual usage’ model for subscription-related services.
We recognize revenue on fixed fee professional services performance obligations based on the proportion of labor hours expended compared to the total hours expected to complete the related performance obligation.
The revenue recognition standards include guidance relating to any tax assessed by a governmental authority that is directly imposed on a revenue-producing transaction between a seller and a customer and may include, but is not limited to, sales, use, value added and excise taxes. We record USF contributions and other regulatory costs on a gross basis in our condensed consolidated statements of operations and comprehensive loss and record surcharges and sales, use and excise taxes billed to our clients on a net basis. The cost of gross USF contributions payable to the USAC and suppliers is presented as a cost of revenue in the condensed consolidated statements of operations and comprehensive loss.

Refer to Note 1 of the notes to condensed consolidated financial statements included in this report.
Off-Balance Sheet Arrangements
As of March 31, 2020, we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K, such as the use of unconsolidated subsidiaries, structured finance, special purpose entities or variable interest entities.
Contractual Obligations
Our principal contractual obligations consist of future payment obligations under our Notes, finance leases to finance data centers and other computer and networking equipment, operating leases for office facilities, and agreements with third parties to provide co-location hosting, telecommunication usage and equipment maintenance services. These commitments as of December 31, 2019 are disclosed in our Annual Report on Form 10-K for the year ended December 31, 2019, and did not change materially during the three months ended March 31, 2020 except for certain hosting and telecommunications agreements. As of March 31, 2020, our commitments under various hosting and telecommunications agreements for terms ranging up to 36 months totaled $8.1 million. These agreements require us to make monthly payments over the service term in exchange for certain network services.

ITEM 3. Quantitative and Qualitative Disclosure about Market Risk
We are exposed to market risk in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in interest rates and foreign currency exchange rates. We do not hold or issue financial instruments for trading purposes. For a discussion of market risk, see “Quantitative and Qualitative Disclosure about Market Risk” in Item 7A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019. Our exposure to market risk has not changed materially since December 31, 2019.
We had cash and cash equivalents, and marketable securities totaling $326.3 million as of March 31, 2020. Cash equivalents and marketable securities were invested primarily in U.S. agency securities, U.S. treasury, municipal bonds, corporate bonds, commercial paper, certificates of deposit and money market funds. 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 100 basis point change in interest rates would not have a material impact on the value of our cash and cash equivalents or marketable investments.
In May 2018, we issued $258.8 million aggregate principal amount of convertible senior notes. 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 condensed consolidated balance sheets, and we present the fair value for required disclosure purposes only.
ITEM 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of March 31, 2020.
Based on management’s evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2020, our disclosure controls and procedures were designed, and were effective, to provide assurance at a reasonable level that the information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to our management as appropriate to allow timely decisions regarding required disclosures.
In designing and evaluating our disclosure controls and procedures, management recognizes that any disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.
Changes in Internal Control over Financial Reporting
During the three months ended March 31, 2020, there was no change in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting despite the fact that all of our employees are working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the COVID-19 situation on our internal controls to minimize the impact on their design and operating effectiveness.

PART II. OTHER INFORMATION
ITEM 1. Legal Proceedings
Information with respect to this Item may be found under the heading “Legal Matters” in Note 10 to the condensed consolidated financial statements in this Quarterly Report on Form 10-Q, which information is incorporated herein by reference.
ITEM 1A. Risk Factors
Except for the below risk factor, which updates those previously disclosed in our Annual Report on Form 10-K as filed with the SEC on February 27, 2020, there have been no material changes from the Risk Factors previously disclosed in Part 1, Item 1A, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019. In addition to the other information set forth in this report, including the below update to Risk Factors, you should carefully consider the Risk Factors discussed in our Annual Report on Form 10-K as they could materially affect our business, financial condition and future results.

The effects of the COVID-19 pandemic have materially affected how we, our clients and business partners are operating, and the duration and extent to which this will impact our future results of operations and overall financial performance remains uncertain.
In December 2019, a novel coronavirus disease known as COVID-19 was reported and on March 11, 2020, the World Health Organization, or WHO, characterized COVID-19 as a pandemic. This pandemic has resulted in a widespread health crisis that has significantly harmed the U.S. and global economies and financial markets, including those on which our common stock and other securities trade, and may impact demand for our solutions.
In accordance with the various shelter-in-place and other social distancing orders of applicable government agencies, all of our employees have transitioned to work-from-home operations and we have canceled all business travel by our employees, which has changed how we operate our business. Our clients and business partners are also subject to various shelter-in-place and other social distancing orders, which have changed the way we interact with our clients and business partners. Moreover, the conditions caused by the COVID-19 pandemic, the extent of which depends upon its prolonged impact, has or may:
harm our ability to renew and maintain our relationships with our existing clients;
cause our existing clients to reduce the number of seats to which they subscribe, seek price concessions, or go out of business, which would harm our revenue;
result in some of our clients failing to comply with the terms of their agreements, including payment terms due to economic uncertainty, financial hardship, and even failure of these businesses, which could result in us being required to take action to collect payments, terminate their subscriptions for our solution, increase accounts receivable, and reduce collections, any which would increase our expenses and harm our revenues and results of operations;
make it more difficult for us to sell increased services or functionality to our existing clients;
reduce the rate of spending on enterprise software solutions or cloud-based enterprise contact center systems generally;
delay prospective clients’ decisions to subscribe to our solution, increase the length of sales cycles, or slow the typical growth in the use of our solutions once clients have initially deployed our solution;
harm our ability to effectively market and sell our solutions, particularly during shelter-in-place and other social distancing orders;
change the mix and sizes or types of organizations that purchase our solution;
delay the introduction of enhancements to our solution and market acceptance of any new features and products;

Table of Contents
harm our ability to grow our international sales and operations;
harm our ability to recruit, onboard and successfully integrate new employees, including members of our direct sales force, both domestically and internationally, as a result of not being able to interface in person;
increase the burden on our technical operations infrastructure, which could harm the capacity, stability, security and performance of our operations infrastructure and potentially leave us more vulnerable to security breaches;
limit our ability to efficiently provide professional services to our larger clients, as those services have typically been performed onsite, which could delay implementation of our solution at new clients;
harm our ability to manage, maintain or increase our network of master agents and resellers to sell our solution, and make it more difficult for them to effectively assist us with their sales efforts;
impact the health and safety of our employees, including our senior management team, and their ability to perform services;
cause our management team to continue to commit significant time, attention and resources to monitor the COVID-19 pandemic and seek to mitigate its effect on our business and workforce; 
lead to the adoption of additional new laws and regulations that we are required to comply with and that could harm our results of operations; and
cause the price per share of our common stock or the trading price of our Notes to continue to experience substantial volatility, and potentially decline, based on developments and announcements related to COVID-19 and its impact on the global and U.S. economy in general or our industry in particular, our failure to meet our guidance or analyst expectations or withdrawal or modification by us of previously issued guidance.
Any of the foregoing factors could significantly harm our future sales, operating results, gross margins and overall financial performance, which could cause us to experience a decreased level of growth of our business and make our future financial results and prospects difficult to predict. The COVID-19 pandemic and its impact on us and the U.S. and global economies, has significantly limited our ability to forecast our future operating results, including our ability to predict revenue and expense levels, and plan for and model future results of operations. Moreover, because a significant portion of our revenue is derived from existing clients, downturns in new sales will not immediately be reflected in our operating results and may be difficult to discern until future periods. Our competitors could experience similar or different impacts as a result of COVID-19, which could result in changes to our competitive landscape.
The duration and extent of the impact from the COVID-19 pandemic depends on future developments that cannot be accurately predicted at this time, such as the ongoing severity and transmission rate of the virus, the extent and effectiveness of containment actions, the duration of shelter-in-place and other restrictions on businesses and society at large, and the specific impact of these and other factors on our business, employees, clients and partners. If we are not able to respond to and manage the impact of such events effectively, our business will be harmed. There are no comparable recent events that provide guidance as to the effect the COVID-19 pandemic may have and, as a result, the ultimate impact of the outbreak on our business and operations is highly uncertain and subject to change. However, the effects could have a material impact on our results of operations and heighten many of the risks described under “Risk Factors” and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2019.
