Accounting Policies [Abstract] |
Reclassification | Reclassification Certain reclassifications have been made to prior period balances in order to conform to the current period’s presentation.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. The accounting estimates and assumptions that require management’s most significant, challenging, and subjective judgment include identifying the performance obligations in the contract, estimating variable consideration, estimating quarterly royalties prior to receiving the royalty reports from the licensee, determining standalone selling price, and allocating consideration in a contract with multiple performance obligations, the assessment of the recoverability of goodwill, the assessment of useful lives and recoverability of other intangible assets and long-lived assets, recognition and measurement of current and deferred income tax assets and liabilities, the assessment of unrecognized tax benefits and purchase accounting resulting from business combinations, among others. Actual results experienced by the Company may differ from management’s estimates. These estimates may change, as new events occur and additional information is obtained, and are recognized in the consolidated financial statements as soon as they become known.
Revenue Recognition | Revenue Recognition Revenue is recognized when control of the promised goods or services is transferred to a customer in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services, which may include various combinations of goods and services which are generally capable of being distinct and accounted for as separate performance obligations. See “Note 4 – Revenue” for a detailed discussion on revenue and revenue recognition.
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents are maintained with various financial institutions.
Short-term Investments | Short-term Investments The Company has historically held investments in debt securities which include corporate bonds and notes, treasury and agency notes and bills, commercial paper, certificates of deposit, and in equity securities consisting of money market funds. The Company classifies all investments as current as the securities are available for use, if needed, for current operations. Marketable Debt Securities The Company classifies its debt securities as available-for-sale (“AFS”), which are accounted for at fair value. For AFS debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more-likely-than-not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through income. For AFS debt securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Company considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in accumulated other comprehensive income or loss on the Consolidated Balance Sheets. Marketable Equity Securities Marketable equity securities are measured at fair value with unrealized gains and losses recognized in other income and expense, net, on the Consolidated Statements of Operations.
Non-Marketable Equity Investments | Non-Marketable Equity Investments Investments in entities over which the Company has the ability to exercise significant influence, but does not hold a controlling interest, are accounted for using the equity method. Under the equity method, the Company records its proportionate share of income or loss in other income and expense, net, in the Consolidated Statements of Operations. Investments in entities over which the Company does not have the ability to exercise significant influence and which do not have readily determinable fair values, are initially recognized at cost and remeasured through earnings when there is an observable transaction involving the same or similar investment of the same issuer, or due to an impairment (referred to as the “measurement alternative”). The fair value of non-marketable equity investments is not estimated if there are no identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investment. The Company monitors its non-marketable securities portfolio for potential impairment. When there is evidence that the expected fair value of the investment has declined to below the recorded cost, the impairment loss is recorded in other income and expense, net, in the Consolidated Statements of Operations.
Fair Value of Financial Instruments | Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The carrying amount of cash equivalents, accounts receivable, accounts payable and accrued liabilities approximates fair value due to the short-term nature of these instruments. Long-term debt is carried at amortized cost and measured at fair value on a quarterly basis for disclosure purposes. See “Note 7 – Fair Value” for further information.
Concentration of Credit and Other Risks | Concentration of Credit and Other Risks Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash equivalents, short-term investments and accounts receivable. The Company follows a corporate investment policy which sets credit, maturity and concentration limits and regularly monitors the composition, market risk and maturities of these investments. The Company believes that any concentration of credit risk in its accounts receivable is substantially mitigated by the Company’s evaluation process, relatively short collection terms and the high level of credit worthiness of its customers. The Company performs ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary but generally requires no collateral. See "Note 18 - Segment and Geographic Information" for further discussion on concentration of credit and other risks.
Allowance for Credit Losses | Allowance for Credit Losses The allowance for credit losses, which includes the allowance for accounts receivable and unbilled contracts receivable, represents the Company’s best estimate of lifetime expected credit losses inherent in those financial assets. The Company’s lifetime expected credit losses are determined using relevant information about past events (including historical experience), current conditions, and reasonable and supportable forecasts that affect collectability. The Company monitors its credit exposure through ongoing credit evaluations of its customers’ financial condition and limits the amount of credit extended when deemed necessary. In addition, the Company performs routine credit management activities such as timely account reconciliations, dispute resolution, and payment confirmations. The Company may employ collection agencies and legal counsel to pursue recovery of defaulted receivables. See “Note 4 – Revenue” for a further discussion of the allowance for credit losses.
Business Combinations | Business Combinations The Company accounts for business combinations using the acquisition method of accounting in accordance with ASC 805, “Business Combinations.” Identifiable assets acquired and liabilities assumed are recorded at their acquisition date fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Acquisition related costs are expensed as incurred. Upon acquisition, the accounts and results of operations are consolidated as of and subsequent to the acquisition date. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions, especially with respect to intangible assets. The Company utilizes commonly accepted valuation techniques, such as the income approach and the cost approach, as appropriate, in establishing the fair value of intangible assets. Typically, key assumptions include projections of cash flows that arise from identifiable intangible assets of acquired businesses as well as discount rates based on an analysis of the weighted average cost of capital, adjusted for specific risks associated with the assets.
Goodwill and Identified Intangible Assets | Goodwill and Identified Intangible Assets Goodwill Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the net tangible and identified intangible assets acquired under a business combination. Goodwill also includes acquired assembled workforce, which does not qualify as an identifiable intangible asset. The Company performs an annual review of the valuation of goodwill in the fourth quarter, or more often if indicators of impairment exist. Triggering events for impairment reviews may be indicators such as adverse industry or economic trends, restructuring actions, lower projections of profitability or a sustained decline in the Company's market capitalization. Evaluations of possible impairment and, if applicable, adjustments to carrying values require the Company to estimate, among other factors, future cash flows, useful lives and fair market values of the Company's assets. When the Company conducts the evaluation of goodwill, the fair value of goodwill is assessed using valuation techniques that require significant management estimates and judgment. In performing the quantitative impairment test for goodwill, the fair value of the reporting unit is compared to its carrying amount. The Company utilizes the market capitalization approach to determine the fair value of a reporting unit. Under the market capitalization approach, the fair value of a reporting unit is estimated based on the trading price of the Company's stock as of the test date, or trading prices over a short period of time immediately prior or subsequent to the test date if such prices more reasonably represent the estimated fair value as of the test date, which is further adjusted by a control premium representing the synergies a market participant would achieve when obtaining control of the business. Identified intangible assets Identified finite-lived intangible assets consist of acquired patents, existing technology, customer relationships and trademarks and trade names resulting from business combinations, as well as acquired patents under asset purchase agreements. The Company’s identified intangible assets are amortized on a straight-line basis over their estimated useful lives, ranging from 1 to 10 years. The Company makes judgments about the recoverability of intangible assets whenever events or changes in circumstances indicate that impairment may exist. If such facts and circumstances exist, the Company assesses the recoverability by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets. If the useful life is shorter than originally estimated, the Company would accelerate the rate of amortization and amortize the remaining carrying value over the new shorter useful life. For further discussion of goodwill and identified intangible assets, see “Note 11 – Goodwill and Identified Intangible Assets.”
Debt Discount and Issuance Costs | Debt Discount and Issuance Costs Debt discount and issuance costs are presented in the Consolidated Balance Sheet as a deduction from the carrying amount of both the short-term debt and long-term debt, and are amortized over the term of the associated debt to interest expense using the effective interest method. In addition, the Company elects to continue to defer the unamortized debt discount and issuance costs when it voluntarily pays down a portion of the debt as the prepayment is factored into the terms agreed to on the debt.
Treasury Stock | Treasury Stock The Company accounts for stock repurchases using the cost method. For reissuance of treasury stock, to the extent that the reissuance price is more than the cost, the excess is recorded as an increase to additional paid-in capital. If the reissuance price is less than the cost, the difference is recorded in additional paid-in capital to the extent there is a cumulative treasury stock paid-in capital balance. Once the cumulative balance is reduced to zero, any remaining difference resulting from the sale of treasury stock below cost is recorded as a reduction of retained earnings.
Leases | Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, accrued liabilities, and noncurrent operating lease liabilities in the Company’s Consolidated Balance Sheets. The ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the leases do not provide an implicit rate, the Company generally uses its incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. The Company’s lease terms may include options to extend or terminate the lease, and these terms are factored into the valuation of ROU assets and liabilities when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. As a practical expedient, the Company elected, for all office and facility leases, not to separate nonlease components from lease components and instead to account for each separate lease component and its associated non-lease components as a single lease component. For additional information regarding the Company's leases, refer to “Note 8 – Leases.”
Research and Development | Research and Development Research and development expense (“R&D expense”) consists primarily of employee-related costs, stock-based compensation expense, engineering consulting expenses associated with new IP development, as well as costs related to patent applications and examinations, reverse engineering, materials, supplies and an allocation of facilities costs. All R&D expense is expensed as incurred.
Stock-based Compensation Expense | Stock-based Compensation Expense Stock-based compensation is measured at the grant date based on the estimated fair value of the award and is recognized as expense on a straight-line basis, net of estimated forfeitures, over the requisite service or performance period. Forfeiture rates are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. If the actual forfeiture rate is materially different from the estimate, stock-based compensation expense could be significantly different from what was recorded in the current period. The Company uses the closing trading price of its common stock on the date of grant as the fair value of awards of restricted stock units (“RSUs”), and performance stock units (“PSUs”) that are based on company-designated performance targets. For performance stock awards that are based on market conditions, or market-based PSUs, fair value is estimated by using a Monte Carlo simulation on the date of grant. The Company estimates the grant-date fair value of stock options and stock to be issued under the employee stock purchase plan (“ESPP”) using the Black-Scholes pricing model. See “Note 15 – Stock-based Compensation Expense” for additional detail. Performance-based PSU awards will vest if certain employee-specific or company-designated performance targets are achieved. If minimum performance thresholds are achieved, each PSU award will convert into the Company’s common stock at a defined ratio depending on the degree of achievement of the performance target designated by each individual award. If minimum performance thresholds are not achieved, then no shares will be issued. The expected levels of achievement are reassessed over the requisite service periods and, to the extent that the expected levels of achievement change, stock-based compensation is adjusted in the period of change and recorded on the statements of operations and the remaining unrecognized stock-based compensation is recorded over the remaining requisite service period. For market-based PSUs, the fair value per award is fixed at the grant date and the amount of compensation expense is not adjusted during the performance period regardless of changes in the level of achievement of the market condition unless it is due to termination.
Income Taxes | Income Taxes The Company must make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments are used in the calculation of tax credits, tax benefits, tax deductions, and in the calculation of certain deferred taxes and tax liabilities. Significant changes to these estimates may result in an increase or decrease to the Company’s tax provision in a subsequent period. The provision for income taxes is comprised of the Company’s current tax liability and changes in deferred income tax assets and liabilities. The calculation of the current tax liability involves dealing with uncertainties in the application of complex tax laws and regulations and in determining the liability for tax positions, if any, taken on the Company’s tax returns in accordance with authoritative guidance on accounting for uncertainty in income taxes. Deferred income taxes are determined based on the differences between the financial reporting and tax basis of assets and liabilities. The Company must assess the likelihood that it will be able to recover its deferred tax assets. If recovery is not likely on a more-likely-than-not basis, the Company must increase its provision for income taxes by recording a valuation allowance against the deferred tax assets that it estimates will not ultimately be recoverable. However, should there be a change in the Company’s ability to recover its deferred tax assets, the provision for income taxes would fluctuate in the period of such change. See “Note 16 – Income Taxes” for additional detail.
Advertising Costs | Advertising Costs Advertising costs are expensed as incurred and are presented within selling, general and administrative expense in the Consolidated Statements of Operations. Advertising expenses were $5.5 million for the year ended December 31, 2022, and were not material for the years ended December 31, 2021 and 2020.
Guarantees and Indemnification | Guarantees and Indemnification The Company has certain financial and performance guarantees which have been issued in the normal course of business. The Company entered into the underlying arrangement with a third-party to facilitate commercial transactions. See "Note 17 - Commitments and Contingencies" for further information regarding the Company's guarantees. The Company provides indemnification of varying scope to certain customers against claims of intellectual property infringement made by third parties arising from the use of the Company’s technologies. In accordance with authoritative guidance for accounting for guarantees, the Company evaluates estimated losses for such indemnification. The Company considers such factors as the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss. To date, no such claims have been filed against the Company and no liability has been recorded in the Company’s financial statements. As permitted under Delaware law, the Company has agreements whereby it indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company believes, given the absence of any such payments in the Company’s history, and the estimated low probability of such payments in the future, that the estimated fair value of these indemnification agreements is immaterial. In addition, the Company maintains a directors’ and officers’ liability insurance policy that is intended to reduce its financial exposure and may enable the Company to recover any payments, should they occur.
Contingencies | Contingencies From time to time, the Company may be involved in legal and administrative proceedings and claims of various types. The Company records a liability in its consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. Management reviews these estimates in each accounting period as additional information becomes known and adjusts the loss provision when appropriate. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in the consolidated financial statements. If a loss is probable but the amount of loss cannot be reasonably estimated, the Company discloses the nature of the loss contingency and the fact that an estimate cannot be made. If a loss is reasonably possible but not probable, the Company discloses the nature of the loss contingency and an estimate of the possible loss, range of loss or the fact that an estimate cannot be made. The Company does not recognize gain contingencies until they are realized. Legal costs incurred in connection with loss contingencies are expensed as incurred. See “Note 17 – Commitments and Contingencies,” for further information regarding the Company’s pending litigation.
Property and Equipment | Property and Equipment Property and equipment are recorded at cost, less accumulated depreciation. Depreciation expense is calculated using the straight-line method over the related assets’ estimated useful lives:
Equipment, furniture and other |  | 1 to 5 years
Leasehold improvements |  | Lesser of related lease term or 5 years
Building and improvements |  | Up to 30 years
Expenditures that materially increase asset life are capitalized, while ordinary maintenance and repairs are expensed as incurred.
Foreign Currency Transactions | Foreign Currency Translation The Company uses the U.S. dollar as its functional currency. Non-U.S. subsidiaries may designate a local currency as their functional currency. The translation of assets and liabilities into U.S. dollars for subsidiaries with a functional currency other than the U.S. dollar is performed using exchange rates in effect at the balance sheet date. The translation of revenues and expenses into U.S. dollars for subsidiaries with a functional currency other than the U.S. dollar is performed using the average exchange rate for the respective period. Gains or losses from cumulative translation adjustments, net of tax, are included as a component of accumulated other comprehensive income (loss) in the Consolidated Balance Sheets. The Company records net foreign exchange transaction gains and losses resulting from the conversion of the transaction currency to the functional currency within other income and expense, net.
Recent Accounting Pronouncements | Recently Adopted Accounting Pronouncements In October 2021, the Financial Accounting Standards Board (“FASB”) issued ASU 2021-08, “Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” (“ASU 2021-08”), which amends the guidance in ASC 805 to require that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Revenue from Contracts with Customers (“Topic 606”). As a result of the amendments, it is expected that an acquirer will generally recognize and measure acquired contract assets and contract liabilities in a manner consistent with how the acquiree recognized and measured them in its preacquisition financial statements. ASU 2021-08 is effective for public business entities for fiscal years beginning after December 15, 2022 and early adoption is permitted. The Company elected to early adopt the new standard on January 1, 2022. The adoption did no t have an impact on the Company’s consolidated financial statements. Recent Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). ASU 2020-04 provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in ASU 2020-04 apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of reference rate reform. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848), which provides further clarification on the scope of Topic 848 so that derivatives affected by the discounting transition are explicitly eligible for certain optional expedients and exceptions in Topic 848. ASU 2020-04 became effective upon issuance and may be applied prospectively to contract modifications made on or before December 31, 2022. ASU 2021-01 became effective upon issuance and may be applied on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020 or prospectively for contract modifications made on or before December 31, 2022. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 ("ASU 2022-06"), which deferred the application dates of Topic 848 to December 31, 2024. The Company currently has debt agreements that reference LIBOR and will apply the amendments prospectively through December 31, 2024 as these contracts are modified to reference other rates. The Company does not anticipate the adoption will have a material impact to the Company's consolidated financial statements.
