Recent Accounting Pronouncements

Income Taxes

In December 2019, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update on income taxes. The new guidance eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. The Company adopted this standard effective January 1, 2021. The adoption of this standard did not have a material impact on the Company's consolidated financial position, results of operations and cash flows.

Facilitation of the Effects of Reference Rate Reform on Financial Reporting

In March 2020, the FASB issued an accounting standard update to guidance applicable to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. This update provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. An entity may elect to apply the amendments for contract modifications by topic or industry subtopic of the codification as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. The Company is currently evaluating the impact of the standard, but does not expect it to have a material impact on its condensed consolidated financial position, results of operations and cash flows.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Significant estimates made by management include estimation for reserves for legal contingencies, the standalone selling price related to revenue recognition, the provision for credit losses related to accounts receivable, contract assets, and available-for-sale debt securities, the provision to reduce obsolete or excess inventory to net realizable value, the provision for estimated returns, as well as sales allowances, the assumptions used in the valuation of stock-based awards and measurement of expense related to performance stock units, the assumptions used in the discounted

cash flows to mark certain of its investments to market, the valuation of the Company’s goodwill, valuation of acquired intangible assets and liabilities, net realizable value of product related and other intangible assets, the provision for income taxes, valuation allowance for deferred tax assets, uncertain tax positions, and the amortization and depreciation periods for contract acquisition costs, intangible and long-lived assets. While the Company believes that such estimates are fair when considered in conjunction with the condensed consolidated financial position and results of operations taken as a whole, the actual amounts of such items, when known, will vary from these estimates.

Available-for-sale Investments

Short-term and long-term available-for-sale investments in debt securities as of March 31, 2021 and December 31, 2020 primarily consist of agency securities, corporate securities and government securities. Investments classified as available-for-sale debt securities are stated at fair value, with unrealized gains and losses, net of taxes, reported in Accumulated other comprehensive loss. The Company classifies its available-for-sale investments as current and non-current based on their actual remaining time to maturity. The Company does not recognize unrealized changes in the fair value of its available-for-sale debt securities in income unless a security is deemed to be impaired.

The allowance for credit losses on the Company's investments in available-for-sale debt securities is determined using a quantitative discounted cash flow analysis if impairment triggers exist after a qualitative screen is completed. Impairment on available-for-sale debt securities is determined on an individual security basis and the security is subject to impairment when its fair value declines below its amortized cost basis. If the fair value is less than the amortized cost basis, management must then determine whether it intends to sell the security or whether it is more likely than not that it will be required to sell the security before it recovers its value. If management intends to sell the security or will more-likely-than-not be required to sell the impaired security before it recovers its value, a credit loss is recorded to Other income, net in the accompanying condensed consolidated statements of income. If management does not intend to sell the security, nor will it more-likely-than-not be required to sell the security before the security recovers its value, management must then determine whether the loss is due to credit loss or other factors. For impairment indicators due to credit loss factors, management establishes an allowance for credit losses with a charge to Other income, net. For impairment indicators due to other factors, management records the loss with a charge to Accumulated other comprehensive loss in the accompanying condensed consolidated balance sheets.

The Company’s investment policy is designed to limit exposure to any one issuer depending on credit quality. The Company uses information provided by third parties to adjust the carrying value of certain of its investments to fair value at the end of each period. Fair values are based on a variety of inputs and may include interest rates, known historical trades, yield curve information, benchmark data, prepayment speeds, credit quality and broker/dealer quotes. See Note 7 for additional information regarding the Company’s investments.

Fair Value Measurements

The authoritative guidance defines fair value as an exit price, representing the amount that would either be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

•Level 1. Observable inputs such as quoted prices in active markets for identical assets or liabilities;

•Level 2. Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and

•Level 3. Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

Available-for-sale securities included in Level 2 are valued utilizing inputs obtained from an independent pricing service (the “Service”) which uses quoted market prices for identical or comparable instruments rather than direct observations of quoted prices in active markets. The Service applies a four level hierarchical pricing methodology to all of the Company’s fixed income securities based on the circumstances. The hierarchy starts with the highest priority pricing source, then subsequently uses inputs obtained from other third-party sources and large custodial institutions. The Service’s providers utilize a variety of inputs to determine their quoted prices. These inputs may include interest rates, known historical trades, yield curve information, benchmark data, prepayment speeds, credit quality and broker/dealer quotes. Substantially all of the Company’s available-for-sale investments are valued utilizing inputs obtained from the Service and accordingly are categorized as Level 2. The Company periodically independently assesses the pricing obtained from the Service and historically has not adjusted the Service's pricing as a result of this assessment. Available-for-sale securities are included in Level 3 when relevant observable inputs for a security are not available.

The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the classification of assets and liabilities within the fair value hierarchy. In certain instances, the inputs used to measure fair value may meet the definition of more than one level of the fair value hierarchy. The input with the lowest level priority is used to determine the applicable level in the fair value hierarchy. See Note 7 for additional information regarding the Company’s fair value measurements.Foreign CurrencyThe functional currency for all of the Company’s wholly-owned foreign subsidiaries is the U.S. dollar. Monetary assets and liabilities of such subsidiaries are remeasured into U.S. dollars at exchange rates in effect at the balance sheet date, and revenues and expenses are remeasured at average rates prevailing during the year. Foreign currency transaction gains and losses are the result of exchange rate changes on transactions denominated in currencies other than the functional currency. The remeasurement of those foreign currency transactions is included in determining net income or loss for the period of exchange.

Accounting for Stock-Based Compensation Plans

The Company has various stock-based compensation plans for its employees and outside directors and accounts for stock-based compensation arrangements in accordance with the authoritative guidance, which requires the Company to measure and record compensation expense in its condensed consolidated financial statements using a fair value method. See Note 8 for further information regarding the Company’s stock-based compensation plans.
