Organization Consolidation And Presentation Of Financial Statements [Abstract]
The Company and Basis of Presentation	NOTE 1 – THE COMPANY AND BASIS OF PRESENTATION Xperi Corporation (the “Company”) licenses its innovative products, technologies and inventions to global electronics companies which, in turn, integrate the technologies into their own consumer electronics and semiconductor products. The Company’s technologies and inventions are widely adopted and used every day by millions of people. The Company’s audio technologies have shipped in billions of devices for the home, mobile and automotive markets. The Company's imaging technologies have been embedded in billions of smartphones and other mobile devices. The Company's semiconductor packaging and interconnect technologies have been licensed to more than 100 customers and have shipped in over 100 billion semiconductor chips. The consolidated financial statements include the accounts of Xperi Corporation, its wholly owned subsidiaries, and a majority-owned subsidiary. In the fourth quarter of 2018, the Company funded a new subsidiary focused , The Company’s fiscal year ends on December 31. The Company employs a calendar month-end reporting period for its quarterly reporting. In the first quarter of 2019, the Company recorded an out-of-period adjustment to decrease current unbilled receivables and decrease retained earnings by Accounting Standards Update (“ASU”) No . 2014-09 (Topic 606) “Revenue from Contracts with Customers.” On December 18, 2019, the Company entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) with TiVo Corporation (“TiVo”) to combine in an all-stock merger of equals transaction (the “Mergers”). The Mergers are expected to close and become effective (the “Effective Time”) during the second quarter of 2020, subject to regulatory approvals, the approval by the shareholders of each company, and other customary closing conditions. Subject to the terms and conditions of the Merger Agreement, each share of Company common stock (“Xperi Common Stock”) issued and outstanding immediately prior to the Effective Time, excluding any shares of Xperi Common Stock that are held in treasury, will be converted into the right to receive one share of common stock of the combined company and each share of TiVo common stock (“TiVo Common Stock”) issued and outstanding immediately prior to the Effective Time, excluding any shares of TiVo Common Stock that are held in treasury, will be converted into the right to receive 0.455 shares of common stock of the combined company. On a pro forma, fully diluted basis, it is expected that immediately following the Effective Time, Xperi stockholders will own approximately 46.5% of the combined company and TiVo stockholders will own approximately 53.5% of the combined company. In connection with the Merger Agreement, the Company and TiVo obtained a debt commitment letter from Bank of America, N.A., Royal Bank of Canada, and Barclays Bank PLC to provide a senior secured first lien term loan B facility in an aggregate principal amount of $1,100 million (the “Debt Financing”), subject to the terms and conditions set forth therein. The proceeds from the Debt Financing may be used (i) to pay fees and expenses incurred in connection with the Mergers and the related transactions, (ii) to accomplish the refinancing of existing indebtedness of the Company and TiVo, and (iii) to the extent of any remaining amounts, for working capital and other general corporate purposes. Reclassification Certain reclassifications have been made to prior period balances in order to conform to the current period’s presentation.

Summary of Significant Accounting Policies	Dec. 31, 2019
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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, difficult, and subjective judgment include the estimation of licensees’ quarterly royalties prior to receiving the royalty reports, the collectability of accounts receivable, the fair value measurements of goodwill, other intangible assets and investments, 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 the valuation and recognition of stock-based compensation expense, and business combinations, among others. Actual results experienced by the Company may differ from management’s estimates. 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 The Company has 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 and common equity securities of publicly traded companies. 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, which are accounted for at fair value with unrealized gains and losses recognized in accumulated other comprehensive income or loss, net of tax, on the Consolidated Balance Sheets. The Company evaluates its debt securities periodically for possible other-than-temporary impairment and reviews factors such as the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer, and the Company’s ability and intent to hold the security until maturity on a more-likely-than-not basis. If the declines in the fair value of the investments are determined to be other-than-temporary, the Company reports the credit loss portion of such decline in other income and expense, net, and the remaining noncredit loss portion in accumulated other comprehensive income. The cost of securities sold is based on the specific identification method. Interest and dividend income and realized gains or losses are included in other income and expense, net. 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. Fair Value of Financial Instruments 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 historical cost and measured at fair value on a quarterly basis for disclosure purposes. See “Note 7 – Fair Value” . 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. At December 31, 2019, the Company had three customers representing 17%, 14% and 11% of aggregate trade receivables, respectively. At December 31, 2018, the Company had two customers representing 17% and 11% of aggregate trade receivables, respectively. The following table sets forth revenue generated from customers which comprise 10% or more of total revenue for the periods indicated: Years Ended December 31, 2019 2018 2017 SK hynix Inc. 17 % 12 % * Intel Corporation 11 % * * Samsung Electronics, Co. Ltd. * 38 % * Micron Technology, Inc. * * 11 % Amkor Technologies, Inc. * * 10 % * Allowance for Doubtful Accounts The Company continually monitors customer payments and maintains a reserve for estimated losses resulting from its customers’ inability to make required payments. In determining the reserve, the Company evaluates the collectibility of its accounts receivable based upon a variety of factors. In cases where the Company becomes aware of circumstances that may impair a specific customer’s ability to meet its financial obligations, the Company records a specific allowance against amounts due. For all other customers, the Company recognizes allowances for doubtful accounts based on its historical write-off experience in conjunction with the length of time the receivables are past due, customer creditworthiness, geographic risk and the current business environment. Actual future losses from uncollectible accounts may differ from the Company’s estimates. The allowance for doubtful accounts balance was $0.6 million and $0.8 million as of December 31, 2019 and December 31, 2018, respectively. 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 reviews impairment of goodwill annually in the fourth quarter, or more frequently if events or circumstances indicate that the goodwill might be impaired. The Company first assesses qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. If, after assessing the totality of events or circumstances, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then the quantitative goodwill impairment test is unnecessary. If, based on the qualitative assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the Company proceeds to perform the quantitative goodwill impairment test. The Company first determines the fair value of a reporting unit using weighted results derived from an income approach and a market approach. The income approach is estimated through the discounted cash flow method based on assumptions about future conditions such as future revenue growth rates, new product and technology introductions, gross margins, operating expenses, discount rates, future economic and market conditions, and other assumptions. The market approach estimates the fair value of the Company’s equity by utilizing the market comparable method which is based on revenue multiples from comparable companies in similar lines of business. The Company then compares the derived fair value of a reporting unit with its carrying amount. If the carrying value of a reporting unit exceeds its fair value, an impairment loss will be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Identified intangible assets . Identified finite-lived intangible assets consist of acquired patents, existing technology, customer relationships, trademarks and trade names, non-compete agreements resulting from business combinations, and 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 15 years . The Company makes judgments about the recoverability of finite-lived intangible assets whenever facts and circumstances indicate that the useful life is shorter than originally estimated or that the carrying amount of assets may not be recoverable. If such facts and circumstances exist, the Company assesses 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. Identified indefinite-lived intangible assets include in-process research and development (IPR&D) resulting from business combinations. The Company evaluates the carrying value of indefinite-lived intangible assets on an annual basis, and an impairment charge would be recognized to the extent that the carrying amount of such assets exceeds their estimated fair value. For further discussion of goodwill and identified intangible assets, see “Note 9 – Acquisitions, Goodwill and Identified Intangible Assets Debt Issuance Costs Debt issuance costs are presented in the consolidated balance sheet as a deduction from the carrying amount of the 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 issuance costs when it pays down a portion of the debt as the prepayment is factored into the terms agreed to on the debt. 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 capital in excess of par value. If the reissuance price is less than the cost, the difference is recorded in capital in excess of par value 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 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 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.” Revenue Recognition The Company derives its revenue primarily from royalty and license fees for rights to use the Company’s intellectual property and technologies (“IP”). Revenue is recognized upon transfer of control of promised products, services or IP rights to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products, services or licensing of the IP rights. See “Note 4 – Revenue” Indemnification 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 has directors’ and officers’ liability insurance coverage that is intended to reduce its financial exposure and may enable the Company to recover any payments, should they occur. Research, Development and Other Related Costs Research and development (“R&D”) is conducted primarily in-house and targets development of audio and image enhancement technologies, chip-scale, multi-chip and wafer level packaging, circuitry, 3D-IC architectures, wafer and die bonding technologies and new machine learning based hardware and software solutions, including semiconductor chip design and fabrication costs. Research, development and other related costs include expenses associated with applications engineering necessary to port and integrate our technologies and products on third party silicon and into end devices. These costs consist primarily of compensation and related costs for personnel, engineering consulting expenses associated with new product and technology development, product commercialization, quality assurance and testing costs, as well as costs related to patent applications and examinations, product "tear downs" and reverse engineering, materials, supplies and equipment depreciation. All research, development and other related costs are expensed Stock-based Compensation Expense The Company accounts for stock-based compensation expense in accordance with the authoritative guidance on share-based payments. Under the provisions of the guidance, stock-based compensation expense is measured at the grant date based on the fair value of the option using a Black-Scholes option pricing model and is recognized as expense on a straight-line basis over the requisite service period, which is generally the vesting period. The authoritative guidance also requires that the Company measure and recognize stock-based compensation expense upon modification of the term of a stock award. The stock-based compensation expense for such modification is the sum of any unamortized expense of the award before modification and the modification expense. The modification expense is the incremental amount of the fair value of the award before the modification and the fair value of the award after the modification, measured on the date of modification. In the event the modification results in a longer requisite period than in the original award, the Company has elected to apply the pool method where the aggregate of the unamortized expense and the modification expense is amortized over the new requisite period on a straight-line basis. In addition, any forfeiture will be based on the original requisite period prior to the modification. Calculating stock-based compensation expense requires the input of highly subjective assumptions, including the expected term of the stock-based awards, stock price volatility, and the pre-vesting option forfeiture rate. The Company estimates the expected life of options granted based on historical exercise patterns, which are believed to be representative of future behavior. The Company estimates the volatility of the Company’s common stock on the date of grant based on historical volatility. The assumptions used in calculating the fair value of stock-based awards represent the Company’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and the Company uses different assumptions, its stock-based compensation expense could be materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. The Company estimates the forfeiture rate based on historical experience of its stock-based awards that are granted, exercised and cancelled. 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 also grants performance share units (PSUs) to employees or consultants. 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 Xperi 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. Based upon the expected levels of achievement, stock-based compensation is recognized on a straight-line basis over the PSUs’ requisite service periods. 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. See “Note 13 – Stock-based Compensation Expense” 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 was 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 the Company’s 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 14 – Income Taxes” 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 loss contingency and an estimate of possible loss or range of loss (unless such 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 15 – Commitments and Contingencies Property and Equipment Property and equipment are recorded at cost, less accumulated depreciation. Depreciation 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 Translation The functional currency of substantially all of the Company’s subsidiaries is the U.S. dollar. Certain subsidiaries have monetary assets and liabilities that are denominated in a currency that is different than the functional currency. The gains and losses resulting from the remeasurement and translation of monetary assets denominated in a currency that is different than the functional currency are reflected in the determination of net income (loss).

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Recent Accounting Pronouncements	NOTE 3 – RECENT ACCOUNTING PRONOUNCEMENTS Recently Adopted Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) In June 2018, the FASB issued : Improvements to Nonemployee Share-based Payment Accounting,” In February 2016, the FASB issued ASU No. 2017-12, “ Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, In February 2016, the FASB issued ASU No. 2016-02, " Leases modified retrospective transition approach and elected the transition option The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed it to carry forward the historical lease classification. Under the optional transition method, the Company opted to continue to apply the legacy guidance in ASC 840, Leases, including its disclosure requirements, in the comparative periods presented in the year it adopted the new leases standard, and therefore did not restate prior period results. The most significant impact from adopting Topic 842 was the initial recognition of operating lease ROU assets and operating lease liabilities of $17.6 million and $18.8 million, respectively, as of January 1, 2019. Operating lease liabilities consist of both current and noncurrent portions with the current portion included in the balance of accrued liabilities. The standard did not materially impact the Company’s Consolidated Statements of Operations and had no impact on cash flows. The cumulative effect of the changes made to the Company's Consolidated Balance Sheet as of January 1, 2019 for the adoption of Topic 842 was as follows (in thousands): Balance at December 31, 2018 Adjustments due to Topic 842 Balance at January 1, 2019 Assets Operating lease right-of-use assets $ — $ 17,594 $ 17,594 Liabilities Accrued liabilities $ 45,336 $ 3,858 (1) $ 49,194 Noncurrent operating lease liabilities $ — $ 13,736 $ 13,736 (1) Consists of a debit adjustment of $1.2 million to deferred rent to eliminate the existing balance and a credit adjustment of $5.1 million to record the current portion of operating lease liabilities.

Revenue From Contract With Customer [Abstract]
Revenue	NOTE 4 – REVENUE Revenue Recognition The Company derives its revenue primarily from royalty and license fees for rights to use the Company’s intellectual property and technologies (“IP”). Revenue is recognized upon transfer of control of promised products, services or IP rights to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products, services or licensing of the IP rights. Certain licensees have entered into fixed fee or minimum guarantee arrangements, whereby licensees pay a fixed fee for the right to incorporate the Company’s technology in the licensee's products over the license term. In arrangements with a minimum guarantee, the fixed fee component corresponds to a minimum number of units or dollars that the customer must produce or pay, with additional per-unit fees for any units or dollars exceeding the minimum. In most cases, the customer pays the fixed license fee in specified installments over the license term. For both fixed fee and minimum guarantee agreements, the Company recognizes the full fixed fee as revenue at the beginning of the license term, when the licensee has the right to use the IP and begins to benefit from the license. If the contract term of a fixed fee or minimum guarantee arrangement is longer than one year, the Company also considers the scheduled payment arrangements to determine whether a significant financing component exists. In general, if the payment arrangements extend beyond the initial twelve months of the contract, the Company treats a portion of the payments as a significant financing component. When the payments are expected to be received within one year or less, the Company does not adjust the promised amount of consideration for the effects of a financing component. The discount rate used for each arrangement reflects the rate that would be used in a separate financing transaction between the Company and the licensee at contract inception and takes into account the credit characteristics of the licensee and market interest rates as of the date of the agreement. As such, the amount of fixed fee revenue recognized at the beginning of the license term will be reduced by the calculated financing component. As payments are received from the licensee, the Company recognizes a portion of the financing component as interest income, reported as other income and expense in the Consolidated Statements of Operations. For certain licensees, royalty revenues are generated based on a licensee’s production or shipment of licensed products incorporating the Company’s IP, technologies or software. Licensees with a per-unit arrangement pay a per-unit royalty for each product manufactured or sold, as set forth in its license agreement. Licensees generally report manufacturing or sales information in the quarter subsequent to when the production or shipment activity takes place. The Company estimates the royalties earned each quarter based on its forecast of manufacturing and sales activity incurred by its licensees in that quarter. Any differences between actual royalties owed by a licensee and the Company’s quarterly estimate are recognized in the following quarter, when the licensee’s royalty report is received. Estimating licensees’ quarterly royalties prior to receiving the royalty reports requires the Company to make significant assumptions and judgments related to forecasted trends and growth rates used to estimate quantities shipped by customers, which could have a material impact on the amount of revenue it reports on a quarterly basis. The Company actively monitors and enforces its IP, including seeking appropriate compensation from customers that have under-reported royalties owed under a license agreement and from third parties that utilize the Company’s intellectual property without a license. As a result of these activities, the Company may, from time to time, recognize revenue from payments resulting from periodic compliance audits of licensees for underreporting royalties incurred in prior periods, as part of a settlement of a patent infringement dispute, or from legal judgments in a license dispute. These recoveries and settlements may cause revenue to be higher than expected during a particular reporting period and such recoveries may not occur in subsequent periods. The Company recognizes revenue from recoveries when a binding agreement has been executed and the Company concludes collection under that agreement is likely. In some instances, the Company may enter into license agreements containing multiple performance obligations that include engineering services in addition to a technology or software license. For such arrangements where all components are capable of being distinct and accounted for as separate performance obligations, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices ordinarily charged to customers, or in some cases by applying a reasonable cost-plus margin. The consideration for engineering services is recognized as the underlying performance obligations are satisfied. Generally, the Company satisfies performance obligations over time and therefore recognizes revenue over time by measuring the progress toward completion of the performance obligation at each reporting period. From time to time, the Company enters into arrangements with licensees in which the Company pays consideration to the licensee. Such payments can take the form of marketing development funds or various rebate incentives. The Company typically accounts for consideration paid to its licensees as a reduction to the transaction price and revenue, unless the payment to the licensee is in exchange for a distinct good or service that the licensee transfers to the Company. In cases where the consideration paid to the licensee is variable, the Company estimates the variable consideration based on the terms of the arrangement and expectations of future outcomes. The Company recognizes the reduction to revenue when it recognizes revenue for transfer of control of promised products, services or IP rights to the licensee. Revenue is recognized gross of withholding taxes that are remitted directly by the Company’s licensees to a local tax authority. For additional detail on the Company’s revenue disaggregated by geographic location, refer to “Note 16 - Segment and Geographic Information Contract Balances Unbilled Contracts Receivable Timing of revenue recognition may differ significantly from the timing of invoicing to customers. Accounts receivable, net, includes amounts billed and currently due from customers. Unbilled contracts receivable represents unbilled amounts expected to be received from customers in future periods, where the revenue recognized to date (or cumulative adjustments to retained earnings in the initial period of adopting Topic 606) exceeds the amount billed, and right to payment is subject to the underlying contractual terms. Unbilled contracts receivable amounts may not exceed their net realizable value and are classified as long-term assets if the payments are expected to be received more than one year from the reporting date. Deferred Revenue Deferred revenue includes payments made by licensees for which the corresponding performance obligations have not yet been fully satisfied by the Company and typically arises where performance obligations are satisfied over time. Additional Disclosures Under Topic 606 The following table presents additional revenue and contract disclosures (in thousands): Years Ended December 31, 2019 2018 Revenue recognized in the period from: Amounts included in deferred revenue at the beginning of the period $ 3,130 $ 2,347 Performance obligations satisfied in previous periods (true ups and licensee reporting adjustments)* $ 2,935 $ 1,323 *True ups represent the differences between the Company’s quarterly estimates of per unit royalty revenue and actual production/sales-based royalties reported by licensees in the following period. Licensee reporting adjustments represent corrections or revisions to previously reported per unit royalties by licensees, generally resulting from the Company’s inquiries or compliance audits. Remaining revenue under contracts with performance obligations represents the aggregate amount of the transaction price allocated to the performance obligations that are unsatisfied (or partially unsatisfied) under the Company’s engineering services contracts. The Company’s remaining revenue under contracts with performance obligations was as follows (in thousands): December 31, 2019 2018 Revenue from contracts with performance obligations expected to be satisfied in: One year or less $ 5,337 $ 3,080 More than one year but less than two years 990 2,289 More than two years 345 — Total $ 6,672 $ 5,369 Practical Expedients The Company expenses sales commissions when incurred because the amortization period generally would have been one year or less. In addition, sales commissions have historically not been a significant expense and are not contemplated to be significant in the future. Sales commissions are recorded in selling, general and administrative expenses in the Consolidated Statement of Operations.

Investments Debt And Equity Securities [Abstract]
Financial Instruments	NOTE 6 – FINANCIAL INSTRUMENTS The Company has 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 and common equity securities of a publicly traded Japanese company. The Company classifies its debt securities as available-for-sale, which are accounted for at fair value with unrealized gains and losses recognized in accumulated other comprehensive income or loss, net of tax, on the Consolidated Balance Sheets. Under ASU 2016-01 (Topic 321), 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. The following is a summary of marketable securities at December 31, 2019 and December 31, 2018 (in thousands): December 31, 2019 Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Values Marketable securities Corporate bonds and notes $ 41,730 $ 29 $ (13 ) $ 41,746 Commercial paper 4,052 4 — 4,056 Total debt securities 45,782 33 (13 ) 45,802 Money market funds 2,601 — — 2,601 Marketable equity securities 3,405 — (2,281 ) 1,124 Total equity securities 6,006 — (2,281 ) 3,725 Total marketable securities $ 51,788 $ 33 $ (2,294 ) $ 49,527 Reported in: Cash and cash equivalents $ 2,601 Short-term investments 46,926 Total marketable securities $ 49,527 December 31, 2018 Cost Gross Unrealized Gains Gross Unrealized Losses Estimated Fair Values Marketable securities Corporate bonds and notes $ 28,623 $ — $ (275 ) $ 28,348 Commercial paper 2,999 — — 2,999 Treasury and agency notes and bills 6,000 — (53 ) 5,947 Total debt securities 37,622 — (328 ) 37,294 Money market funds 11,499 — — 11,499 Marketable equity securities 5,662 — (2,217 ) 3,445 Total marketable securities $ 17,161 $ — $ (2,217 ) $ 14,944 Total marketable securities $ 54,783 $ — $ (2,545 ) $ 52,238 Reported in: Cash and cash equivalents $ 11,499 Short-term investments 40,739 Total marketable securities $ 52,238 At December 31, 2019 and December 31, 2018, the Company had $121.5 million and $154.4 million, respectively, in cash, cash equivalents and short-term investments. A significant portion of these amounts was held in marketable securities, as shown above. The remaining balance of $72.0 million and $102.1 million at December 31, 2019 and December 31, 2018, respectively, was cash held in operating accounts not included in the tables above. Debt Securities The gross realized gains and losses on sales of marketable debt securities were not significant during the years ended December 31, 2019, 2018 and 2017. Unrealized losses on marketable debt securities were $0.1 million and $0.3 million, net of tax, as of December 31, 2019 and December 31, 2018, respectively. These amounts were related to temporary fluctuations in the value of available-for-sale securities and were due primarily to changes in interest rates and market and credit conditions of the underlying securities. Certain investments with a temporary decline in value are not considered to be other-than-temporarily impaired as of December 31, 2019 because the Company has the intent and ability to hold these investments to allow for recovery, does not anticipate having to sell these securities with unrealized losses and continues to receive interest at the maximum contractual rate. For the years ended December 31, 2019, 2018 and 2017, respectively, the Company did not record any impairment charges related to its marketable securities. The following table summarizes the fair value and gross unrealized losses related to individual available-for-sale debt securities at December 31, 2019 and 2018, which have been in a continuous unrealized loss position, aggregated by investment category and length of time (in thousands): December 31, 2019 Less Than 12 Months 12 Months or More Total Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Corporate bonds and notes $ 20,031 $ (10 ) $ 8,753 $ (3 ) $ 28,784 $ (13 ) Total $ 20,031 $ (10 ) $ 8,753 $ (3 ) $ 28,784 $ (13 ) December 31, 2018 Less Than 12 Months 12 Months or More Total Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Corporate bonds and notes $ 5,488 $ (2 ) $ 22,860 $ (273 ) $ 28,348 $ (275 ) Treasury and agency notes and bills — — 5,947 (53 ) 5,947 (53 ) Commercial paper 2,999 — — — 2,999 — Total $ 8,487 $ (2 ) $ 28,807 $ (326 ) $ 37,294 $ (328 ) The estimated fair value of marketable debt securities by contractual maturity at December 31, 2019 is shown below (in thousands). Actual maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations without call or prepayment penalties. Estimated Fair Value Due in one year or less $ 29,491 Due in one to two years 16,311 Due in two to three years — Total $ 45,802 Equity Securities On September 19, 2018, the Company purchased seven million common shares of Onkyo Corporation (“Onkyo”), a publicly traded Japanese company and a long-standing customer of the Company, pursuant to the Capital Alliance Agreement (“Agreement”) entered into between the two parties on September 3, 2018. Upon making the investment, the Company held a 6.3% ownership interest in Onkyo. Due to changes in business expectations, the Company determined not to continue discussions on the business alliance. On July 5, 2019, the Company sold approximately 2.8 million shares of Onkyo stock, for which a realized gain of $0.9 million was recognized for the year ended December 31, 2019. There were no sales of the Onkyo investment during 2018. The Company intends to sell the remaining shares over time depending on market conditions. The Company recorded unrealized losses on its Onkyo investment of $0.9 million and $2.2 million during the years ended December 31, 2019 and 2018, respectively, and none for the year ended December 31, 2017. Cumulative unrealized losses on the investment amounted to $2.3 million through December 31, 2019. Derivatives In the first quarter of 2019 , the Company began to use derivative financial instruments to manage foreign currency exchange rate risk. The Company does not enter into derivative transactions for trading purposes. Cash flows from the derivative programs are classified as cash flows from operating activities in the Consolidated Statement Cash Flows The Company’s derivative financial instruments consist of deliverable and non-deliverable foreign currency forward contracts, which are used primarily to hedge balance sheet and certain expenditure exposures. These instruments are generally short-term in nature, with typical maturities of less than one year, and are subject to fluctuations in foreign exchange rates. Fair values for derivative financial instruments are based on prices computed using third-party valuation models and are classified as Level 2 in accordance with the three-level hierarchy of fair value measurements.

Fair Value Disclosures [Abstract]
Fair Value	NOTE 7 – FAIR VALUE The Company follows the authoritative guidance for fair value measurement and the fair value option for financial assets and financial liabilities. The Company carries its financial instruments at fair value with the exception of its long-term debt. Level 1 Quoted prices in active markets for identical assets. Level 2 Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. When applying fair value principles in the valuation of assets, the Company is required to maximize the use of quoted market prices and minimize the use of unobservable inputs. The Company calculates the fair value of its Level 1 and Level 2 instruments based on the exchange traded price of similar or identical instruments, where available, or based on other observable inputs. There were no significant transfers into or out of Level 1 or Level 2 that occurred between December 31, 2018 and December 31, 2019.

Leases [Abstract]
Leases	NOTE 8 - LEASES Under Topic 842, a contract is a lease, or contains a lease, if the contract conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. To determine whether a contract conveys the right to control the use of an identified asset for a period of time, an entity shall assess whether, throughout the period of use, the entity has both of the following: (a) the right to obtain substantially all of the economic benefits from use of the identified asset; and (b) the right to direct the use of the identified asset. The Company leases office and research facilities and office equipment under operating leases which expire at various dates through 2028. The Company’s leases have remaining lease terms of one year to nine years, some of which may include options to extend the leases for five years or longer, and some of which may include options to terminate the leases within one year or less. Leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases 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 (e.g., common-area maintenance costs) from lease components (e.g., fixed payments including rent) and instead to account for each separate lease component and its associated non-lease components as a single lease component. The Company uses its incremental borrowing rate for purposes of discounting lease payments. Lease cost is summarized in the table below (in thousands): Years Ended December 31, 2019 2018 2017 Operating lease cost (1) $ 7,971 $ 7,188 $ 6,423 (1) Includes short-term leases and variable lease costs, which were immaterial.

Diluted net income (loss) per share is computed using the treasury stock method to calculate the weighted average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential dilutive common shares include unvested restricted stock awards and units and incremental common shares issuable upon the exercise of stock options, less shares from assumed proceeds. The assumed proceeds calculation includes actual proceeds to be received from the employee upon exercise and the average unrecognized stock compensation cost during the period. For each of the years ended December 31, 2019, 2018 and 2017, there was no difference in the weighted average number of common shares used for the calculation of basic and diluted loss per share as the effect of all potentially dilutive shares outstanding was anti-dilutive. A total of 1.3 million, 2.9 million and 3.0 million shares subject to stock options and restricted stock awards and units were excluded for the years ended December 31, 2019, 2018 and 2017, respectively, from the computation of diluted net loss per share because including them would have been anti-dilutive.

Shareholders' Equity	NOTE 12 – SHAREHOLDERS’ EQUITY Stock Repurchase Programs In August 2007, the Company’s Board of Directors (“the Board”) authorized a plan to repurchase the Company’s outstanding shares of common stock dependent on market conditions, share price and other factors. As of December 31, 2019, the total amount authorized for repurchases is $450.0 million. As of December 31, 2019, the Company had repurchased a total of approximately 13,279,000 shares of common stock, since inception of the plan, at an average price of $26.25 per share for a total cost of $348.6 million.

Stock Option Plans The 2003 Plan In February 2003, the Board adopted and the Company’s stockholders approved the 2003 Equity Incentive Plan (“2003 Plan”). Under the 2003 Plan, incentive stock options may be granted to the Company’s employees at an exercise price of no less than 100% of the fair value on the date of grant, and non-statutory stock options may be granted to the Company’s employees, non-employee directors and consultants at an exercise price of no less than 85% of the fair value.

The value and the vesting of such performance awards and units are generally linked to one or more performance goals or other specific performance goals determined by the Company, in each case on a specified date or dates or over any period or periods determined by the Company, and range from zero to 100 percent of the grant. Employee Stock Purchase Plans In August 2003, the Board adopted the 2003 Employee Stock Purchase Plan (the “ESPP”), which was approved by the Company’s stockholders in September 2003 and became effective February 1, 2004. Subsequently, the Board adopted the International Employee Stock Purchase Plan (the “International ESPP”) in June 2008. The ESPP has a series of consecutive, overlapping 24-month offering periods. The first offering period commenced February 1, 2004, the effective date of the ESPP, as determined by the Board of Directors. Individuals who own less than 5% of the Company’s voting stock, are scheduled to work more than 20 hours per week and whose customary employment is for more than five months in any calendar year may join an offering period on the first day of the offering period or the beginning of any semi-annual purchase period within that period. Individuals who become eligible employees after the start date of an offering period may join the ESPP at the beginning of any subsequent semi-annual purchase period. Participants may contribute up to 20% of their cash earnings through payroll deductions, and the accumulated deductions will apply to the purchase of shares on each semi-annual purchase date. The purchase price per share will equal 85% of the fair market value per share on the participant’s entry date into the offering period or, if lower, 85% of the fair market value per share on the semi-annual purchase date. An eligible employee’s right to buy the Company’s common stock under the ESPP may not accrue at a rate in excess of $25,000 of the fair market value of such shares per calendar year for each calendar year of an offering period. If the fair market value per share of the Company’s common stock on any purchase date is less than the fair market value per share on the start date of the 24-month offering period, then that offering period will automatically terminate and a new 24-month offering period will begin on the next business day. All participants in the terminated offering will be transferred to the new offering period. As of December 31, 2019, there were approximately 1,052,000 shares reserved for grant under the ESPP and the International ESPP, collectively. Dividends Stockholders of the Company’s common stock are entitled to receive dividends when declared by the Company’s Board of Directors. The Company has paid a quarterly dividend of $0.20 per share since March 2015. Dividends declared were $0.80 per common share in each of 2019, 2018 and 2017. Assumed Plans Certain stock awards plans were assumed in the DTS acquisition during December 2016. The awards outstanding under these plans are included in the tables above. No future grants will be made under these plans.

The 2017 estimated per share fair value of the grant was $4.62 before estimated forfeitures. The total fair value of restricted stock awards and units vested during the years ended December 31, 2019, 2018 and 2017 was $30.1 million, $30.4 million and $22.7 million, respectively. The total intrinsic value of options exercised during the years ended December 31, 2019, 2018 and 2017 was $0.2 million, $1.0 million and $5.5 million, respectively. The intrinsic value is calculated as the difference between the market value on the date of exercise and the exercise price of the shares. As of December 31, 2019, the unrecognized stock-based compensation balance after estimated forfeitures consisted of $0.1 million related to unvested stock options, to be recognized over an estimated weighted average amortization period of 1.5 years, and $40.3 million related to restricted stock awards and units, including performance-based awards and units, to be recognized over an estimated weighted average amortization period of 2.3 years. As of December 31, 2018, the unrecognized stock-based compensation balance after estimated forfeitures related to unvested stock options was $0.3 million to be recognized over an estimated weighted average amortization period of 2.0 years and $40.6 million related to restricted stock awards and units, including performance-based awards and units, to be recognized over an estimated weighted average amortization period of 2.2 years. The Company uses the Black-Scholes option pricing model to determine the estimated fair value of options. The fair value of each option grant is determined on the date of grant and the expense is recorded on a straight-line basis. The assumptions used in the model include expected life, volatility, risk-free interest rate, and dividend yield. The Company’s determinations of these assumptions are outlined below. Expected life – The expected life assumption is based on analysis of the Company’s historical employee exercise patterns. The expected life of options granted under the ESPP represents the offering period of two years. Volatility – Volatility is calculated using the historical volatility of the Company’s common stock for a term consistent with the expected life. Historical volatility of the Company’s common stock is also utilized for the ESPP. Risk-free interest rate – The risk-free interest rate assumption is based on the U.S. Treasury rate for issues with remaining terms similar to the expected life of the options. Dividend yield – Expected dividend yield is calculated based on cash dividends declared by the Board for the previous four quarters and dividing that result by the average closing price of the Company’s common stock for the quarter. Cash dividends are not paid on options, restricted stock units or unvested restricted stock awards. In addition, the Company estimates forfeiture rates. Forfeitures are estimated at the time of grant and revised in subsequent periods if actual forfeitures differ from those estimates. Historical data is used to estimate pre-vesting option forfeitures and record stock-based compensation expense only for those awards that are expected to vest. The following assumptions were used to value the awards granted: Years Ended December 31, 2019* 2018* 2017 Expected life (in years) — — 4.7 Risk-free interest rate — — 1.8% Dividend yield — — 2.9% Expected volatility — — 29.8% *There were no options granted during the years ended December 31, 2019 and 2018. The following assumptions were used to value the ESPP shares: Years Ended December 31, 2019 2018 2017 Expected life (years) 2.0 2.0 2.0 Risk-free interest rate 1.7 - 2.5% 2.2 - 2.7% 1.2 - 1.3% Dividend yield 3.5 - 5.4% 3.6 - 3.9% 2.0 - 2.5% Expected volatility 51.7 - 53.4% 39.4 - 41.7% 28.3 - 30.8% For the years ended December 31, 2019, 2018 and 2017, an aggregate of 386,000, 306,000 and 164,000 common shares, respectively, were purchased pursuant to the ESPP. Modifications From time to time, the Company enters into consulting agreements with its departing employees. Some of these agreements may include continued vesting of the departing employees’ stock awards and an extension of the exercise period from the standard 90 days from employment termination date to the termination of the consulting agreement. There were no modifications in 2019 and 2018, respectively. In 2017, there was one modification with the impact on the Company’s financial statements deemed not to be material.

Significant components of the Company’s deferred tax assets and liabilities are as follows (in thousands): December 31, 2019 2018 Deferred tax assets Net operating losses $ 10,142 $ 10,368 Research tax credits 13,475 14,717 Foreign tax credits — 27,092 Expenses not currently deductible 14,640 14,623 Basis difference in fixed and intangible assets 3,593 3,494 Capitalized research expenses 23,785 8,965 Gross deferred tax assets 65,635 79,259 Valuation allowance (37,243 ) (41,942 ) Net deferred tax assets 28,392 37,317 Deferred tax liabilities Revenue recognition (32,466 ) (63,367 ) Operating leases (2,665 ) — Acquired intangible assets, domestic (17,165 ) (27,323 ) Acquired intangible assets, foreign (2,171 ) (7,944 ) Net deferred tax liabilities $ (26,075 ) $ (61,317 ) At December 31, 2019 and 2018, the Company had a valuation allowance of $37.2 million and $41.9 million, respectively, related to federal, state, and foreign deferred tax assets that the Company believes will not be realizable on a more-likely-than-not basis. The $4.7 million decrease from the prior year is primarily comprised of $27.9 million attributable to a decrease in valuation allowance recorded against tax credits, offset by $23.2 million increase in valuation allowance primarily related to U.S. federal capitalized research expenses. The need for a valuation allowance requires an assessment of both positive and negative evidence when determining whether it is more likely than not that deferred tax assets are recoverable. Such assessment is required on a jurisdiction-by-jurisdiction basis. In making such assessment, significant weight is given to evidence that can be objectively verified such as recent earnings (or loss) history, carryback of certain tax attributes and reversals of existing taxable temporary differences. Lesser weight is given to subjective evidence such as tax-planning strategies and projected future income based on management’s assumptions. After considering both positive and negative evidence, the Company released valuation allowance on U.S. federal tax credits since it was more likely than not that these tax attributes would be utilized as a result of the foreign tax refund filing. Additionally, the Company increased its valuation allowance on deferred tax assets primarily related to U.S. federal capitalized research expenses, U.S. state deferred tax assets, and certain foreign deferred tax assets based on its recent financial results and having insufficient objectively verifiable future sources of income. In the future, the Company may release valuation allowance and recognize certain deferred tax assets depending on achievement of future profitability in relevant jurisdictions or implementation of tax planning strategies that enable the Company to utilize deferred tax assets that would otherwise be unused. Any release of valuation allowance could have the effect of decreasing the income tax provision in the period the valuation allowance is released. The Company continues to monitor the likelihood that it will be able to recover its deferred tax assets, including those for which a valuation allowance is recorded. There can be no assurance that the Company will generate profits or implement tax strategies in future periods enabling it to fully realize its deferred tax assets. The timing of recording a valuation allowance or the reversal of such valuation allowance is subject to objective factors that cannot be readily predicted in advance. Adjustments could be required in the future if the Company concludes that it is more likely than not that deferred tax assets are not recoverable. A provision for a valuation allowance could have the effect of increasing the income tax provision in the period the valuation allowance is provided. As of December 31, 2019, the Company had federal net operating loss carryforwards of approximately $3.1 million and state net operating loss carryforwards of approximately $66.4 million. Substantially all of the federal net operating loss carryforwards are carried over from the acquired entity, DTS in 2016. The state net operating loss carryforwards are carried over from acquired entities, DTS in 2016, Ziptronix in 2015, and Siimpel Corporation in 2010. The federal net operating loss carryforwards, if not utilized, will begin to expire on various dates beginning in 2026. The state net operating loss carryforwards, if not utilized, will begin to expire on various dates beginning in 2021, and will continue to expire through 2035. In addition, the Company has research tax credit carryforwards of approximately $1.7 million for federal purposes, which was carried over from prior years. The federal research tax credit will start to expire in 2034 and will continue to expire through 2035. The Company also has research tax credit carryforwards of approximately $15.4 million for state purposes and $0.6 million for foreign purposes, which do not expire. Under the provisions of the Internal Revenue Code, substantial ownership changes may limit the amount of net operating loss and tax credit carryforwards that can be utilized annually in the future to offset taxable income. In addition, for losses generated after December 31, 2017, the Tax Act modified the maximum deduction of net operating loss, eliminated carryback, and provided an indefinite carryforward. A reconciliation of the statutory U.S. federal income tax rate to the Company’s effective tax rate is as follows: Years Ended December 31, 2019 2018 2017 U.S. federal statutory rate $ (17,442 ) $ 1,451 $ (20,420 ) State, net of federal benefit 281 59 49 Stock-based compensation expense 2,807 3,883 1,706 Executive compensation limitation 411 1,538 — Research tax credit (2,038 ) 248 (1,851 ) Foreign withholding tax 10,328 33,063 14,719 Transaction costs 974 — — Foreign tax rate differential 1,907 474 12,112 Foreign tax credit (7,795 ) (33,554 ) (13,343 ) Change in valuation allowance (8,238 ) 7,721 13,497 U.S. tax reform (2,970 ) (6,333 ) (7,868 ) Unrecognized tax benefits 2,994 300 108 Change in estimates (1,300 ) (10 ) (608 ) Others 1,057 (167 ) 114 Total $ (19,024 ) $ 8,673 $ (1,785 ) On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“Tax Act”) was signed into law. The Tax Act introduced a broad range of tax reform measures that significantly changed the federal income tax laws. As of December 31, 2017, the Company recorded a provisional tax expense in the Statement of Operations of approximately $5.6 million, comprised of approximately $13.5 million tax expense from recording additional valuation allowance against federal tax credits due to certain provisions of the Tax Act, offset by approximately $7.9 million of tax benefit from the remeasurement of U.S. deferred taxes using the 21% tax rate at which the Company expects them to reverse in the future. The one-time transition tax on post-1986 foreign unremitted earnings did not have a material impact on the Company’s effective tax rate. The Company continues to monitor supplemental legislation and technical interpretations of the tax law that may cause the final impact from the Tax Act to differ from the amounts previously recorded. At December 31, 2019, the Company asserts that it will not permanently reinvest its foreign earnings outside the U.S. The Company anticipates that the cash from its foreign earnings may be used domestically to fund operations, settle a portion of the outstanding debt obligation, or used for other business needs. The accumulated undistributed earnings generated by its foreign subsidiaries was approximately $107.3 million. Substantially all of these earnings will not be taxable upon repatriation to the United States since under the Tax Act they will be treated as previously taxed income from the one-time transition tax, Global Intangible Low-Taxed Income or dividends-received deduction. The withholding taxes related to the distributable cash of the Company’s foreign subsidiaries are not expected to be material. During the fourth quarter of fiscal 2019, the Company filed a refund claim for foreign taxes previously withheld by licensees in Korea based on recent court rulings in Korea and other business factors. These withheld foreign taxes were claimed as a foreign tax credit in the U.S. As a result of the refund claim, the Company recorded a non-current income tax receivable of $65.2 million in other assets, an unrecognized tax benefit of $48.2 million recorded in other long-term liabilities, and a reduction in deferred tax assets of $17.0 million. At December 31, 2019, the Company recorded a foreign exchange loss of $0.7 million. As of December 31, 2019, unrecognized tax benefits approximated $87.3 million, of which $82.9 million would affect the effective tax rate if recognized. As of December 31, 2018, unrecognized tax benefits approximated $33.6 million, of which $21.3 million would affect the effective tax rate if recognized. The Company believes that its unrecognized tax benefits as of December 31, 2019 will decrease by approximately $4.3 million within the next twelve months due to expiring statute of limitations. The Company anticipates that the unrecognized tax benefit, related to a future Korean withholding tax refund claim, will continue to increase in the next twelve months due to additional taxes withheld on royalty payments by Korean licensees. The increase in the unrecognized tax benefit would more-likely-than-not be offset by the income tax receivable from the future Korean withholding tax refund claim and therefore, do not expect a significant impact on the Company’s tax provision. The reconciliation of the Company’s Years Ended December 31, 2019 2018 2017 Total unrecognized tax benefits at January 1 $ 33,552 $ 33,506 $ 30,088 Gross increases and decreases due to tax positions taken in prior periods — (540 ) 2,457 Gross increases and decreases due to tax positions taken in the current period 54,048 586 961 Gross increases and decreases due to settlements with taxing authorities — — — Gross increases and decreases due to lapses in applicable statutes of limitations (306 ) — — Total unrecognized tax benefits at December 31 $ 87,294 $ 33,552 $ 33,506 It is the Company’s At December 31, 2019, the Company’s 2014 through 2018 tax years were open and subject to potential examination in one or more jurisdictions. In addition, in the U.S., any net operating losses or credits that were generated in prior years but not yet fully utilized in a year that is closed under the statute of limitations may also be subject to examination. The Internal Revenue Service is currently in the process of completing the examination of one of the Company’s domestic subsidiaries for tax year 2014. The Company estimates that the financial outcome of this examination will not be material to its Statement of Operations. In addition, the Company has submitted a withholding tax refund claim with the Korean authorities and the final outcome is not anticipated to be settled within the next twelve months.

Commitments and Contingencies

Commitments and Contingencies	Dec. 31, 2019
Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 15 – COMMITMENTS AND CONTINGENCIES Leases The Company leases office and research facilities and office equipment under operating leases which expire at various dates through 2028. The terms of some of the Company’s leases provide for rental payments on a graduated scale. Lease expense is recorded on a straight-line basis over the lease term. For further details, refer to “Note 8 – Leases.” Purchase and Other Commitments Under certain contractual arrangements, the Company may be obligated to pay up to approximately $10.7 million over an estimated period of approximately five years if certain milestones are achieved. Contingencies At each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. The Company is currently unable to predict the final outcome of lawsuits to which it is a party and therefore cannot determine the likelihood of loss nor estimate a range of possible loss. An adverse decision in any of these proceedings could significantly harm the Company’s business and consolidated financial position, results of operations or cash flows. The Company and its subsidiaries are involved in litigation matters and claims in the normal course of business. In the past, the Company and its subsidiaries have litigated to enforce their respective patents and other intellectual property rights, to enforce the terms of license agreements, to protect trade secrets, to determine the validity and scope of the proprietary rights of others and to defend themselves or their customers against claims of infringement or invalidity. The Company expects to be involved, either directly or through its subsidiaries, in similar legal proceedings in the future, including proceedings regarding infringement of its patents, and proceedings to ensure proper and full payment of royalties by customers under the terms of its license agreements. The existing and any future legal actions may harm the Company’s business. For example, an adverse decision in any of these legal actions could result in a loss of the Company’s proprietary rights; reduce or limit the value of the Company’s licensed technology; negatively impact the Company’s stock price, its business, consolidated financial position, results of operations, royalties, billings, or cash flows; subject the Company to significant liabilities; or require the Company to seek licenses from others. Furthermore, legal actions could cause an existing customer or strategic partner to cease making royalty or other payments to the Company, or to challenge the validity and enforceability of patents owned by the Company’s subsidiaries or the scope of license agreements with the Company’s subsidiaries, and could significantly damage the Company’s relationship with such customer or strategic partner and, as a result, prevent the adoption of the Company’s other technologies by such customer or strategic partner. Litigation could also severely disrupt or shut down the business operations of customers or strategic partners of the Company’s subsidiaries, which in turn would significantly harm ongoing relations with them and cause the Company to lose royalty revenue. The costs associated with legal proceedings are typically high, relatively unpredictable, and not completely within the Company’s control. These costs may be materially higher than expected, which could adversely affect the Company’s operating results and lead to volatility in the price of its common stock. Whether or not determined in the Company’s favor or ultimately settled, litigation diverts managerial, technical, legal, and financial resources from the Company’s business operations.

Segment and Geographic Informat

Segment and Geographic Information	12 Months Ended
Segment and Geographic Information	Dec. 31, 2019
Segment Reporting [Abstract]
Segment and Geographic Information	NOTE 16 – SEGMENT AND GEOGRAPHIC INFORMATION The Company reports its financial results within two reportable segments: (1) Product Licensing and (2) Semiconductor and IP Licensing. There are certain corporate overhead costs that are not allocated to these reportable segments because these operating amounts are not considered in evaluating the operating performance of the Company’s business segments. The Chief Executive Officer is also the Chief Operating Decision Maker (“CODM”) as defined by the authoritative guidance on segment reporting. The Product Licensing segment is comprised of the Company’s audio and imaging businesses, which the Company licenses through the DTS, HD Radio, and IMAX Enhanced brands. These licenses typically include the delivery of software and/or hardware-based solutions to the Company’s customers or to their suppliers. Product Licensing revenue is derived primarily from sales into the home, automotive and mobile markets. The Semiconductor and IP Licensing segment includes our Tessera, Invensas and Invensas Bonding Technologies subsidiaries, which license semiconductor packaging and interconnect technologies and associated IP. Semiconductor and IP Licensing revenue is derived from technology and IP licenses to semiconductor companies, foundries and packaging companies. The Company has a long history of developing and monetizing next-generation technologies, including chip-scale and multi-chip packaging solutions as well as low-temperature wafer and die bonding solutions. Today, the Company is actively developing and licensing 3D semiconductor packaging, interconnect and bonding solutions for semiconductors that are used in every day products such as smartphones, tablets, and laptops as well as servers used in datacenters. The Company also provides engineering services to its customers to assist them in their evaluation and adoption of the Company’s technologies including the transition into high volume production. The Company does not identify or allocate assets by reportable segment, nor does the CODM evaluate reportable segments using discrete asset information. Reportable segments do not record inter-segment revenue and accordingly there are none to report. The Company does not allocate other income and expense to reportable segments. Although the CODM uses operating income to evaluate reportable segments, operating costs included in one segment may benefit other segments. The following table sets forth the Company’s segment revenue, operating expenses and operating income (loss) for the years ended December 31, 2019, 2018 and 2017 (in thousands): Years Ended December 31, 2019 2018 2017 Revenue: Product licensing segment $ 198,124 $ 219,708 $ 167,923 Semiconductor and IP licensing segment 81,943 186,425 205,809 Total revenue 280,067 406,133 373,732 Operating expenses: Product licensing segment 181,804 180,727 172,745 Semiconductor and IP licensing segment 44,074 73,519 87,838 Unallocated operating expenses (1) 122,897 127,907 144,649 Total operating expenses 348,775 382,153 405,232 Operating income (loss): Product licensing segment 16,320 38,981 (4,822 ) Semiconductor and IP licensing segment 37,869 112,906 117,971 Unallocated operating expenses (1) (122,897 ) (127,907 ) (144,649 ) Total operating income (loss) $ (68,708 ) $ 23,980 $ (31,500 ) (1) Unallocated operating expenses consist primarily of selling, general and administrative expenses and stock-based compensation. These expenses are not allocated because these amounts are not considered in evaluating the operating performance of the Company’s business segments. Amortization and depreciation are included in segment operating income (loss) as shown below (in thousands): Years Ended December 31, 2019 2018 2017 Amortization and depreciation: Product licensing segment $ 93,403 $ 93,582 $ 95,823 Semiconductor and IP licensing segment 13,264 21,544 23,308 Total amortization and depreciation $ 106,667 $ 115,126 $ 119,131 A significant portion of the Company’s revenue is derived from licensees headquartered outside of the U.S., principally in Asia, and it is expected that this revenue will continue to account for a significant portion of total revenues in future periods.

Summary Of Significant Accounting Policies (Policies)	Dec. 31, 2019
Accounting Policies [Abstract]
Basis of Accounting	The consolidated financial statements include the accounts of Xperi Corporation, its wholly owned subsidiaries, and a majority-owned subsidiary. In the fourth quarter of 2018, the Company funded a new subsidiary focused ,
Fiscal Period	The Company’s fiscal year ends on December 31. The Company employs a calendar month-end reporting period for its quarterly reporting.
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, difficult, and subjective judgment include the estimation of licensees’ quarterly royalties prior to receiving the royalty reports, the collectability of accounts receivable, the fair value measurements of goodwill, other intangible assets and investments, 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 the valuation and recognition of stock-based compensation expense, and business combinations, among others. Actual results experienced by the Company may differ from management’s estimates.
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 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 and common equity securities of publicly traded companies. 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, which are accounted for at fair value with unrealized gains and losses recognized in accumulated other comprehensive income or loss, net of tax, on the Consolidated Balance Sheets. The Company evaluates its debt securities periodically for possible other-than-temporary impairment and reviews factors such as the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer, and the Company’s ability and intent to hold the security until maturity on a more-likely-than-not basis. If the declines in the fair value of the investments are determined to be other-than-temporary, the Company reports the credit loss portion of such decline in other income and expense, net, and the remaining noncredit loss portion in accumulated other comprehensive income. The cost of securities sold is based on the specific identification method. Interest and dividend income and realized gains or losses are included in other income and expense, net. 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.
Fair Value of Financial Instruments	Fair Value of Financial Instruments 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 historical cost and measured at fair value on a quarterly basis for disclosure purposes. See “Note 7 – Fair Value” .
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. At December 31, 2019, the Company had three customers representing 17%, 14% and 11% of aggregate trade receivables, respectively. At December 31, 2018, the Company had two customers representing 17% and 11% of aggregate trade receivables, respectively. The following table sets forth revenue generated from customers which comprise 10% or more of total revenue for the periods indicated: Years Ended December 31, 2019 2018 2017 SK hynix Inc. 17 % 12 % * Intel Corporation 11 % * * Samsung Electronics, Co. Ltd. * 38 % * Micron Technology, Inc. * * 11 % Amkor Technologies, Inc. * * 10 % *
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The Company continually monitors customer payments and maintains a reserve for estimated losses resulting from its customers’ inability to make required payments. In determining the reserve, the Company evaluates the collectibility of its accounts receivable based upon a variety of factors. In cases where the Company becomes aware of circumstances that may impair a specific customer’s ability to meet its financial obligations, the Company records a specific allowance against amounts due. For all other customers, the Company recognizes allowances for doubtful accounts based on its historical write-off experience in conjunction with the length of time the receivables are past due, customer creditworthiness, geographic risk and the current business environment. Actual future losses from uncollectible accounts may differ from the Company’s estimates. The allowance for doubtful accounts balance was $0.6 million and $0.8 million as of December 31, 2019 and December 31, 2018, respectively.
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 reviews impairment of goodwill annually in the fourth quarter, or more frequently if events or circumstances indicate that the goodwill might be impaired. The Company first assesses qualitative factors to determine whether it is necessary to perform the quantitative goodwill impairment test. If, after assessing the totality of events or circumstances, the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then the quantitative goodwill impairment test is unnecessary. If, based on the qualitative assessment, it is determined that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the Company proceeds to perform the quantitative goodwill impairment test. The Company first determines the fair value of a reporting unit using weighted results derived from an income approach and a market approach. The income approach is estimated through the discounted cash flow method based on assumptions about future conditions such as future revenue growth rates, new product and technology introductions, gross margins, operating expenses, discount rates, future economic and market conditions, and other assumptions. The market approach estimates the fair value of the Company’s equity by utilizing the market comparable method which is based on revenue multiples from comparable companies in similar lines of business. The Company then compares the derived fair value of a reporting unit with its carrying amount. If the carrying value of a reporting unit exceeds its fair value, an impairment loss will be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. Identified intangible assets . Identified finite-lived intangible assets consist of acquired patents, existing technology, customer relationships, trademarks and trade names, non-compete agreements resulting from business combinations, and 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 15 years . The Company makes judgments about the recoverability of finite-lived intangible assets whenever facts and circumstances indicate that the useful life is shorter than originally estimated or that the carrying amount of assets may not be recoverable. If such facts and circumstances exist, the Company assesses 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. Identified indefinite-lived intangible assets include in-process research and development (IPR&D) resulting from business combinations. The Company evaluates the carrying value of indefinite-lived intangible assets on an annual basis, and an impairment charge would be recognized to the extent that the carrying amount of such assets exceeds their estimated fair value. For further discussion of goodwill and identified intangible assets, see “Note 9 – Acquisitions, Goodwill and Identified Intangible Assets
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs are presented in the consolidated balance sheet as a deduction from the carrying amount of the 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 issuance costs when it 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 capital in excess of par value. If the reissuance price is less than the cost, the difference is recorded in capital in excess of par value 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 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.”
Revenue Recognition	Revenue Recognition The Company derives its revenue primarily from royalty and license fees for rights to use the Company’s intellectual property and technologies (“IP”). Revenue is recognized upon transfer of control of promised products, services or IP rights to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products, services or licensing of the IP rights. See “Note 4 – Revenue” Revenue Recognition The Company derives its revenue primarily from royalty and license fees for rights to use the Company’s intellectual property and technologies (“IP”). Revenue is recognized upon transfer of control of promised products, services or IP rights to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products, services or licensing of the IP rights. Certain licensees have entered into fixed fee or minimum guarantee arrangements, whereby licensees pay a fixed fee for the right to incorporate the Company’s technology in the licensee's products over the license term. In arrangements with a minimum guarantee, the fixed fee component corresponds to a minimum number of units or dollars that the customer must produce or pay, with additional per-unit fees for any units or dollars exceeding the minimum. In most cases, the customer pays the fixed license fee in specified installments over the license term. For both fixed fee and minimum guarantee agreements, the Company recognizes the full fixed fee as revenue at the beginning of the license term, when the licensee has the right to use the IP and begins to benefit from the license. If the contract term of a fixed fee or minimum guarantee arrangement is longer than one year, the Company also considers the scheduled payment arrangements to determine whether a significant financing component exists. In general, if the payment arrangements extend beyond the initial twelve months of the contract, the Company treats a portion of the payments as a significant financing component. When the payments are expected to be received within one year or less, the Company does not adjust the promised amount of consideration for the effects of a financing component. The discount rate used for each arrangement reflects the rate that would be used in a separate financing transaction between the Company and the licensee at contract inception and takes into account the credit characteristics of the licensee and market interest rates as of the date of the agreement. As such, the amount of fixed fee revenue recognized at the beginning of the license term will be reduced by the calculated financing component. As payments are received from the licensee, the Company recognizes a portion of the financing component as interest income, reported as other income and expense in the Consolidated Statements of Operations. For certain licensees, royalty revenues are generated based on a licensee’s production or shipment of licensed products incorporating the Company’s IP, technologies or software. Licensees with a per-unit arrangement pay a per-unit royalty for each product manufactured or sold, as set forth in its license agreement. Licensees generally report manufacturing or sales information in the quarter subsequent to when the production or shipment activity takes place. The Company estimates the royalties earned each quarter based on its forecast of manufacturing and sales activity incurred by its licensees in that quarter. Any differences between actual royalties owed by a licensee and the Company’s quarterly estimate are recognized in the following quarter, when the licensee’s royalty report is received. Estimating licensees’ quarterly royalties prior to receiving the royalty reports requires the Company to make significant assumptions and judgments related to forecasted trends and growth rates used to estimate quantities shipped by customers, which could have a material impact on the amount of revenue it reports on a quarterly basis. The Company actively monitors and enforces its IP, including seeking appropriate compensation from customers that have under-reported royalties owed under a license agreement and from third parties that utilize the Company’s intellectual property without a license. As a result of these activities, the Company may, from time to time, recognize revenue from payments resulting from periodic compliance audits of licensees for underreporting royalties incurred in prior periods, as part of a settlement of a patent infringement dispute, or from legal judgments in a license dispute. These recoveries and settlements may cause revenue to be higher than expected during a particular reporting period and such recoveries may not occur in subsequent periods. The Company recognizes revenue from recoveries when a binding agreement has been executed and the Company concludes collection under that agreement is likely. In some instances, the Company may enter into license agreements containing multiple performance obligations that include engineering services in addition to a technology or software license. For such arrangements where all components are capable of being distinct and accounted for as separate performance obligations, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices ordinarily charged to customers, or in some cases by applying a reasonable cost-plus margin. The consideration for engineering services is recognized as the underlying performance obligations are satisfied. Generally, the Company satisfies performance obligations over time and therefore recognizes revenue over time by measuring the progress toward completion of the performance obligation at each reporting period. From time to time, the Company enters into arrangements with licensees in which the Company pays consideration to the licensee. Such payments can take the form of marketing development funds or various rebate incentives. The Company typically accounts for consideration paid to its licensees as a reduction to the transaction price and revenue, unless the payment to the licensee is in exchange for a distinct good or service that the licensee transfers to the Company. In cases where the consideration paid to the licensee is variable, the Company estimates the variable consideration based on the terms of the arrangement and expectations of future outcomes. The Company recognizes the reduction to revenue when it recognizes revenue for transfer of control of promised products, services or IP rights to the licensee. Contract Balances Unbilled Contracts Receivable Timing of revenue recognition may differ significantly from the timing of invoicing to customers. Accounts receivable, net, includes amounts billed and currently due from customers. Unbilled contracts receivable represents unbilled amounts expected to be received from customers in future periods, where the revenue recognized to date (or cumulative adjustments to retained earnings in the initial period of adopting Topic 606) exceeds the amount billed, and right to payment is subject to the underlying contractual terms. Unbilled contracts receivable amounts may not exceed their net realizable value and are classified as long-term assets if the payments are expected to be received more than one year from the reporting date. Deferred Revenue Deferred revenue includes payments made by licensees for which the corresponding performance obligations have not yet been fully satisfied by the Company and typically arises where performance obligations are satisfied over time. Practical Expedients The Company expenses sales commissions when incurred because the amortization period generally would have been one year or less. In addition, sales commissions have historically not been a significant expense and are not contemplated to be significant in the future. Sales commissions are recorded in selling, general and administrative expenses in the Consolidated Statement of Operations.
Indemnification	Indemnification 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 has directors’ and officers’ liability insurance coverage that is intended to reduce its financial exposure and may enable the Company to recover any payments, should they occur.
Research, Development and Other Related Costs	Research, Development and Other Related Costs Research and development (“R&D”) is conducted primarily in-house and targets development of audio and image enhancement technologies, chip-scale, multi-chip and wafer level packaging, circuitry, 3D-IC architectures, wafer and die bonding technologies and new machine learning based hardware and software solutions, including semiconductor chip design and fabrication costs. Research, development and other related costs include expenses associated with applications engineering necessary to port and integrate our technologies and products on third party silicon and into end devices. These costs consist primarily of compensation and related costs for personnel, engineering consulting expenses associated with new product and technology development, product commercialization, quality assurance and testing costs, as well as costs related to patent applications and examinations, product "tear downs" and reverse engineering, materials, supplies and equipment depreciation. All research, development and other related costs are expensed
Stock-based Compensation Expense	Stock-based Compensation Expense The Company accounts for stock-based compensation expense in accordance with the authoritative guidance on share-based payments. Under the provisions of the guidance, stock-based compensation expense is measured at the grant date based on the fair value of the option using a Black-Scholes option pricing model and is recognized as expense on a straight-line basis over the requisite service period, which is generally the vesting period. The authoritative guidance also requires that the Company measure and recognize stock-based compensation expense upon modification of the term of a stock award. The stock-based compensation expense for such modification is the sum of any unamortized expense of the award before modification and the modification expense. The modification expense is the incremental amount of the fair value of the award before the modification and the fair value of the award after the modification, measured on the date of modification. In the event the modification results in a longer requisite period than in the original award, the Company has elected to apply the pool method where the aggregate of the unamortized expense and the modification expense is amortized over the new requisite period on a straight-line basis. In addition, any forfeiture will be based on the original requisite period prior to the modification. Calculating stock-based compensation expense requires the input of highly subjective assumptions, including the expected term of the stock-based awards, stock price volatility, and the pre-vesting option forfeiture rate. The Company estimates the expected life of options granted based on historical exercise patterns, which are believed to be representative of future behavior. The Company estimates the volatility of the Company’s common stock on the date of grant based on historical volatility. The assumptions used in calculating the fair value of stock-based awards represent the Company’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and the Company uses different assumptions, its stock-based compensation expense could be materially different in the future. In addition, the Company is required to estimate the expected forfeiture rate and only recognize expense for those shares expected to vest. The Company estimates the forfeiture rate based on historical experience of its stock-based awards that are granted, exercised and cancelled. 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 also grants performance share units (PSUs) to employees or consultants. 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 Xperi 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. Based upon the expected levels of achievement, stock-based compensation is recognized on a straight-line basis over the PSUs’ requisite service periods. 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. See “Note 13 – Stock-based Compensation Expense”
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 was 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 the Company’s 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 14 – Income Taxes”
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 loss contingency and an estimate of possible loss or range of loss (unless such 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 15 – Commitments and Contingencies
Property and Equipment	Property and Equipment Property and equipment are recorded at cost, less accumulated depreciation. Depreciation 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 Translation	Foreign Currency Translation The functional currency of substantially all of the Company’s subsidiaries is the U.S. dollar. Certain subsidiaries have monetary assets and liabilities that are denominated in a currency that is different than the functional currency. The gains and losses resulting from the remeasurement and translation of monetary assets denominated in a currency that is different than the functional currency are reflected in the determination of net income (loss).
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) In June 2018, the FASB issued : Improvements to Nonemployee Share-based Payment Accounting,” In February 2016, the FASB issued ASU No. 2017-12, “ Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, In February 2016, the FASB issued ASU No. 2016-02, " Leases modified retrospective transition approach and elected the transition option The Company elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things, allowed it to carry forward the historical lease classification. Under the optional transition method, the Company opted to continue to apply the legacy guidance in ASC 840, Leases, including its disclosure requirements, in the comparative periods presented in the year it adopted the new leases standard, and therefore did not restate prior period results. The most significant impact from adopting Topic 842 was the initial recognition of operating lease ROU assets and operating lease liabilities of $17.6 million and $18.8 million, respectively, as of January 1, 2019. Operating lease liabilities consist of both current and noncurrent portions with the current portion included in the balance of accrued liabilities. The standard did not materially impact the Company’s Consolidated Statements of Operations and had no impact on cash flows. The cumulative effect of the changes made to the Company's Consolidated Balance Sheet as of January 1, 2019 for the adoption of Topic 842 was as follows (in thousands): Balance at December 31, 2018 Adjustments due to Topic 842 Balance at January 1, 2019 Assets Operating lease right-of-use assets $ — $ 17,594 $ 17,594 Liabilities Accrued liabilities $ 45,336 $ 3,858 (1) $ 49,194 Noncurrent operating lease liabilities $ — $ 13,736 $ 13,736 (1) Consists of a debit adjustment of $1.2 million to deferred rent to eliminate the existing balance and a credit adjustment of $5.1 million to record the current portion of operating lease liabilities. Recent Accounting Pronouncements In September 2016, the FASB issued ASU No. 2016-13, “ Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments in the first quarter of 2020 The Company has completed its initial assessment and currently expects the as of January 1, 2020 will not be material.
