Organization Consolidation And Presentation Of Financial Statements [Abstract]
Description of Business and Summary of Significant Accounting Policies	(1) Description of Business and Summary of Significant Accounting Policies Description of Business Digimarc Corporation (“Digimarc” or the “Company”), an Oregon corporation, is the inventor of a platform that enables a more efficient, reliable and economical means of automatic identification. The Digimarc Platform can apply a unique identifier to virtually all media objects—including product packaging, commercial print, audio and video—that can be automatically identified by an enabled ecosystem of industrial scanners, smartphones and other interfaces. These capabilities allow Digimarc and its partners to supply a wide range of solutions for retail and supply chain operations, consumer engagement, media management and security. The Digimarc Platform features three core capabilities for the identification, discovery and quality management of media. Digimarc Barcode integrates the identification function, which is a novel data carrier encoded into media in ways that are generally imperceptible to people, permitting the carrier to be repeated many times over the surface of the enhanced media. Digimarc Discover represents the discovery function, which is software for computing devices and network interfaces that recognize and decode indicia of the identity of media. These include, but are not limited to, Digimarc Barcodes, Quick Response Codes, Universal Product Codes, certain other GS1 approved one-dimensional codes and relevant contextual data. Digimarc Verify incorporates the quality management function, a suite of software tools used to inspect and verify that the identification and discovery of media are both accurate and effective. Together, these core capabilities enable organizations, application developers, and other solution providers to build new and improve existing automatic identification solutions. Principles of Consolidation The consolidated financial statements include the accounts of Digimarc and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated. Use of Estimates The preparation of the consolidated financial statements in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”) requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. The Company’s accounting policies for revenue recognition require higher degrees of judgment than others in their application. Management bases its estimates on historical experience and on other assumptions that are believed to be reasonable in the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Reclassifications Certain prior period amounts in the accompanying consolidated financial statements and notes thereto have been reclassified to conform to current period presentation, including the reclassification of revenue and expense accounts to better align with the presentation provided by our peers in the software industry. These reclassifications had no material effect on the results of operations or financial position for any period presented. Cash Equivalents The Company considers all highly liquid marketable securities with original maturities of 90 days or less at the date of acquisition to be cash equivalents. Cash equivalents include money market securities, commercial paper and pre-refunded municipals totaling $18,568 and $10,436 at December 31, 2020 and 2019, respectively. Cash equivalents are carried at either cost or amortized cost depending on the type of security, which approximates fair value. Marketable Securities The Company considers all investments with original maturities over 90 days that mature in less than one-year from the balance sheet date to be short-term marketable securities. Short-term marketable securities primarily include commercial paper, pre-refunded municipals and corporate notes. The Company’s marketable securities are classified as held-to-maturity and are reported at amortized cost, which approximates market value. A decline in the market value of any security below amortized cost that is deemed to be other-than-temporary results in a reduction in the carrying amount. The impairment is charged to earnings and a new cost basis for the security is established. To determine whether an impairment is other-than-temporary, the Company considers whether it has the ability and intent to hold the investment until a market price recovery and considers whether evidence indicating that the cost of the investment is recoverable outweighs evidence to the contrary. There have been no other-than-temporary impairments identified or recorded by the Company. Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to yield using a method that approximates the effective interest method. Under this method, dividend and interest income are recognized when earned. Fair Value of Financial Instruments Accounting Standards Codification (“ASC”) 820 “ Fair Value Measurements and Disclosures • Level 1—Pricing inputs are quoted prices available in active markets for identical investments as of the reporting date. • Level 2—Pricing inputs are quoted for similar investments, or inputs that are observable, either directly or indirectly, for substantially the full term through corroboration with observable market data. Level 2 includes investments valued at quoted prices adjusted for legal or contractual restrictions specific to these investments. • Level 3—Pricing inputs are unobservable for the investment; that is, the inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. The estimated fair values of the Company’s financial instruments, which include cash equivalents, accounts receivable, accounts payable and other accrued liabilities, approximate their carrying values due to the short-term nature of these instruments. The Company’s fair value hierarchy for its cash equivalents and marketable securities as of December 31, 2020 and 2019, respectively, was as follows: December 31, 2020 Level 1 Level 2 Level 3 Total Money market securities $ 10,988 $ — $ — $ 10,988 Commercial paper — 36,478 — 36,478 Pre-refunded municipals — 26,697 — 26,697 Corporate notes — 2,437 — 2,437 Total $ 10,988 $ 65,612 $ — $ 76,600 December 31, 2019 Level 1 Level 2 Level 3 Total Money market securities $ 746 $ — $ — $ 746 Commercial paper — 25,481 — 25,481 Corporate notes — 5,773 — 5,773 U.S. treasuries — 4,040 — 4,040 Total $ 746 $ 35,294 $ — $ 36,040 The fair value maturities of the Company’s cash equivalents and marketable securities as of December 31, 2020 are as follows: Maturities by Period Total Less 1 year 1-5 years 5 - 10 years More than 10 years Cash equivalents and marketable securities $ 76,600 $ 76,600 $ — $ — $ — Concentrations of Business and Credit Risk A significant portion of the Company’s business depends on a limited number of large contracts. The loss of any large contract may result in loss of revenue and margin on a prospective basis. Financial instruments that potentially subject Digimarc to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, and accounts receivable. Digimarc places its cash and cash equivalents with major banks and financial institutions and at times deposits may exceed insured limits. Other than cash used for operating needs, which may include short-term marketable securities with the Company’s principal banks, Digimarc’s investment policy limits its credit exposure to any one financial institution or type of financial instrument by limiting the maximum of 5% of its cash equivalents and marketable securities or $1,000, whichever is greater, to be invested in any one issuer except for the U.S. government, U.S. federal agencies and U.S. backed securities, which have no limits, at the time of purchase. The Company’s investment policy also limits its credit exposure by limiting the maximum of 40% of its cash equivalents and marketable securities, or $15,000, whichever is greater, to be invested in any one industry category, (e.g., financial or energy industries), at the time of purchase. As a result, Digimarc’s credit risk associated with cash and cash equivalents and marketable securities is believed to be minimal. Contingencies The Company evaluates all pending or threatened contingencies or commitments, if any, that are reasonably likely to have a material adverse effect on the Company’s operations or financial position. The Company assesses the probability of an adverse outcome and determines if it is remote, reasonably possible or probable as defined in accordance with ASC 450 “ Contingencies Goodwill The Company tests goodwill for impairment annually and whenever events or changes in circumstances indicate that the carrying value may exceed the fair value, in accordance with ASC 350 “ Intangibles – Goodwill and Other Impairment of Long-Lived Assets The Company assesses long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, in accordance with ASC 360 “ Property, Plant and Equipment Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to future net undiscounted cash flows expected to be generated by the assets over their remaining useful life. If such assets are considered to be impaired, the impairment would be recognized in operating results at the amount by which the carrying amount of the assets exceeds the fair value of the assets. Fair value is determined based on discounted cash flows or appraised values, depending on the nature of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. Research and Development Research and development costs are expensed as incurred in accordance with ASC 730 “ Research and Development Software Development Costs Under ASC 985 “ Software Patent Costs Costs associated with the application and award of patents in the U.S. and various other countries are capitalized and amortized on a straight-line basis over the term of the patents as determined at award date, which varies depending on the pendency period of the application. Capitalized patent costs, also referred to as patent prosecution costs, include internal legal labor, professional legal fees, government filing fees and translation fees related to expanding the Company’s patent portfolio. Costs associated with the maintenance and annuity fees of patents are accounted for as prepaid assets at the time of payment and amortized over the shorter of the maintenance period or remaining life of the related patent. Revenue Recognition See Note 2 for detailed disclosures of the Company’s revenue recognition policy. Stock-Based Compensation The Company accounts for stock-based compensation in accordance with ASC 718 “ Compensation—Stock Compensation For stock option awards, the Company uses the Black-Scholes option pricing model as its method of valuation. The Company’s determination of the fair value on the date of grant (measurement date) is affected by its stock price as well as assumptions regarding a number of subjective variables. These variables include, but are not limited to, the expected life of the award, the Company’s expected stock price volatility over the term of the award, the risk-free interest rate and the expected dividend yield. For restricted stock awards which vest upon meeting a service condition , the Company uses the fair market value of the Company’s common stock on the date of the grant (measurement date) as its method of valuation . For performance restricted stock awards which vest upon meeting both a market condition and a service condition, the Company uses the Monte Carlo Simulation model as its method of valuation. The Company’s determination of the fair value on the date of grant (measurement date) is affected by its stock price as well as assumptions regarding a number of subjective variables. These variables include, but are not limited to, the expected stock price volatility over the term of the award and the risk-free interest rate. Although the fair value of stock-based awards is determined in accordance with ASC 718 and Staff Accounting Bulletin (“SAB”) No. 107 “ Shared-Based Payment ” Income Taxes The Company accounts for income taxes in accordance with ASC 740 “ Income Taxes The Company records valuation allowances on deferred tax assets if, based on available evidence, it is more-likely-than-not that all or some portion of the assets will not be realized. The Company is subject to income taxes within the U.S. and other countries, and, in the ordinary course of business, there are transactions and calculations where the ultimate tax determination is uncertain. The Company reports a liability (or contra asset) for unrecognized tax benefits resulting from uncertain tax positions taken (or expected to be taken) on a tax return. The Company recognizes interest and penalties, if any, related to the unrecognized tax benefits in income tax expense. Accounting Pronouncements Issued But Not Yet Adopted In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, “ Financial Instruments - Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments In December 201 9 , the FASB issued ASU No. 201 9 - 1 2, “ Income Taxes ( ASC 740) Simplifying the Accounting for Income Taxes ,” that removes certain exceptions to the general principles and also improves consistent application of and simplify generally accepted accounting principles . The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020 . Early adoption is permitted. The Company does not expect the impact of the adoption of this standard to have a material impact on the Company’s financial condition, results of operations and disclosures.

Revenue Recognition

Revenue Recognition [Abstract]
Revenue Recognition	(2) Revenue Recognition The Company derives its revenue primarily from software development services and software subscriptions. Applicable revenue recognition criteria are considered separately for each performance obligation as follows: • Service revenue consists primarily of revenue earned from the performance of software development services. The majority of service contracts are structured as time and materials consulting agreements. Revenue for services is generally as the services are performed. Billing for services rendered generally occurs within one month after the services are provided. • Subscription revenue consists primarily of revenue earned from the sale of software products and to a lesser extent the licensing of intellectual property. The majority of subscription contracts are recurring, paid in advance and recognized over the term of the subscription, which is typically one to three years. Customer arrangements may contain multiple performance obligations such as software development services, software products, and maintenance and support fees. The Company accounts for individual products and services separately if they are distinct. To determine the transaction price, the Company considers the terms of the contract and the Company’s customary business practices. Some contracts may contain variable consideration. In those cases, the Company estimates the amount of variable consideration based on the sum of probability-weighted amounts in a range of possible consideration amounts. As part of this assessment, the Company will evaluate whether any of the variable consideration is constrained and if it is the Company will not include it in the transaction price. The consideration is allocated between distinct products and services based on their stand-alone selling prices. For items that are not sold separately, the Company estimates the standalone selling price based on reasonably available information, including market conditions, specific factors affecting the Company, and information about the customer. For distinct products and services, the Company typically recognizes the revenue associated with these performance obligations as they are delivered to the customer. Products and services that are not capable of being distinct are combined with other products or services until a distinct performance obligation is identified. All revenue recognized in the Consolidated Statements of Operations is considered to be revenue from contracts with customers. The following table provides information about disaggregated revenue by major target market in the Company’s single reporting segment: Year Ended Year Ended December 31, December 31, 2020 2019 Government Service $ 13,263 $ 12,793 Subscription 1,683 1,518 Total Government 14,946 14,311 Retail Service $ 618 $ 456 Subscription 4,942 4,802 Total Retail 5,560 5,258 Media Service $ — $ — Subscription 3,484 3,418 Total Media 3,484 3,418 Total $ 23,990 $ 22,987 The Company has contract assets from contracts with customers that are classified as “trade accounts receivable.” Financial information about trade accounts receivable is included in Note 6. The Company has contract liabilities from contracts with customers that are classified as “deferred revenue.” Deferred revenue consists of billings in advance for services and subscriptions for which the performance obligation has not been satisfied. The following table provides information about contract liabilities from contracts with customers: December 31, December 31, 2020 2019 Deferred revenue, current $ 3,002 $ 3,172 Deferred revenue, long-term 30 59 Total $ 3,032 $ 3,231 The Company recognized $2,993 of revenue during the year ended December 31, 2020 that was included in the contract liability balance as of December 31, 2019. The aggregate amount of the transaction price from contractual obligations that are unsatisfied or partially unsatisfied was $17,921 and $17,759, as of December 31, 2020 and 2019, respectively.

Stock-Based Compensation	(4) Stock-Based Compensation Stock-based compensation includes expense charges for all stock-based awards to employees and directors. These awards include stock option grants, restricted stock awards and restricted stock unit awards. Stock-based compensation expense related to internal labor is capitalized to software and patent costs based on direct labor hours charged to capitalized software and patent costs. Determining Fair Value Stock Options The Company estimates the fair value of stock options on the date of grant (measurement date) using the Black-Scholes option pricing model. The Company recognizes the fair value of stock option awards on a straight-line basis over the vesting period of the award. The following inputs are used in the Black-Scholes option pricing model to estimate the fair value of stock options: Stock Price. The stock price represents the fair market value of the Company’s common stock on the date of the grant. Expected Life. The expected life of awards granted represents the period of time that they are expected to be outstanding. The Company determines the expected life based on historical experience with similar awards, giving consideration to the contractual terms and vesting schedules of the awards. Stock options granted generally vest over a service period of three years and have a contractual term of ten years. Expected Volatility. The Company estimates the volatility of its common stock at the date of grant based on the historical volatility of its common stock based on historical prices over the most recent period commensurate with the expected life of the award. Risk-Free Interest Rate. The Company determines the risk-free interest rate using current U.S. treasury yields for bonds with a maturity commensurate with the expected life of the award. Expected Dividend Yield. The expected dividend yield is derived by the Company’s expected annual dividend rate over the expected term divided by the fair value of the Company’s common stock at the grant date. Black Scholes Option Valuation Inputs: Year Ended Year Ended December 31, December 31, 2020 2019 Stock price $ 15.36 $ 39.54 Expected life (years) 3.25 3.20 Expected volatility 70.91 % 58.68 % Risk-free interest rate 0.25 % 1.51 % Expected dividend yield 0 % 0 % Restricted Stock The fair value of restricted stock awards is based on the fair market value of the Company’s common stock on the date of the grant (measurement date), and is recognized on a straight-line basis over the vesting period of the award. Restricted stock awards granted generally vest over a service period of three to four years for employee grants and one to three years for director grants. Restricted Stock Units The fair value of restricted stock unit (“RSU”) awards, which vest upon meeting a service condition, is based on the fair market value of the Company’s common stock on the date of the grant (measurement date) and is recognized on a straight-line basis over the service period of the award, which is generally 3 years. Performance Restricted Stock Units The fair value of performance restricted stock unit (“PRSU”) awards, which vest upon meeting both a market condition, such as exceeding a target stock price in the future, and a service condition, is determined on the date of grant (measurement date) using the Monte Carlo Simulation model. The Company recognizes the fair value of the award on a straight-line basis over the service period of the award, which is generally 3 years. The following inputs are used in the Monte Carlo Simulation model to estimate the fair value of PRSUs: Stock Price. The stock price represents the fair market value of the Company’s common stock on the date of the grant. Expected Volatility. The Company estimates the volatility of its common stock at the date of grant based on the historical volatility of its common stock based on historical prices over the most recent period commensurate with the term of the award.

Notes Payable [Abstract]
Notes Payable	(10) Notes Payable Promissory Note under the Paycheck Protection Program On April 16, 2020, the Company entered into a Promissory Note with Stearns Bank, N.A. in an aggregate principal amount of $5,032 (the “Note”), pursuant to the Paycheck Protection Program (the “PPP”) under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). The Note matures two years from the disbursement date and bears interest at a rate of 1.000% per annum, with the first six months of interest deferred. Principal and interest are payable monthly commencing six months after the disbursement date and may be prepaid by the Company at any time prior to maturity with no prepayment penalties. Under the terms of the CARES Act, PPP loan recipients can apply for and be granted forgiveness for all or a portion of loans granted under the PPP. The Note is subject to forgiveness to the extent proceeds are used for payroll costs, including payments required to continue group health care benefits, and certain rent, utility, and mortgage interest expenses (collectively, “Qualifying Expenses”), pursuant to the terms and limitations of the PPP. The Company believes that it used all of the proceeds from the Note for Qualifying Expenses. However, no assurance is provided that the Company will obtain forgiveness of the Note in whole or in part. On June 29, 2020, the Company was notified by Stearns Bank, N.A. that the Note was transferred to The Loan Source, Inc., (the “Lender”) who will be responsible for servicing the Note going forward, including administering loan forgivenes s. On September 15, 2020, the Company filed its application for 100% forgiveness of the Note. The application was reviewed by the Lender and submitted to the Small Business Administration (“SBA”) for approval on December 17, 2020. The SBA will, subject to any review of the Company’s loan or application, remit payment of the appropriate forgiveness amount to the Lender within 90 days following the date the Lender submitted its decision to the SBA. If the SBA reviews the Company’s loan or application, then it may take longer than 90 days for any determination to be made as to whether the Note will be forgiven in whole, in part or at all. Principal and interest payments can be deferred until the forgiveness process is completed as no payments would be required if the Note is forgiven. The Note provides that the Company must obtain lender consent in the event of a “change of ownership.” On October 2, 2020, the SBA released a procedural notice that defined “change of ownership” as used in PPP loans to mean the transfer, whether in one or more transactions, of at least 20% of the common stock or other ownership interest of a PPP borrower. On November 20, 2020, the Company received consent from the Lender for the expected “change of ownership” to be triggered by the conversion of the Series B Convertible Preferred Stock issued on October 1, 2020, under the Subscription Agreement with TCM Strategic Partners L.P.

The Board of Directors has the authority to issue the undesignated preferred stock in one or more series and to determine the powers, preferences and rights and the qualifications, limitations or restrictions granted to or imposed upon any wholly unissued series of undesignated preferred stock and to fix the number of shares constituting any series and the designation of such series, without any further vote or action by the shareholders. The issuance of preferred stock may have the effect of delaying, deferring or preventing a change of control of the Company without further action by shareholders and may adversely affect the voting and other rights of the holders of common stock. The Board of Directors authorized 10 shares of Series A Redeemable Nonvoting Preferred stock (“Series A Preferred”) that were issued to certain executive officers at the time of formation. The Series A Preferred has no voting rights, except as required by law, and may be redeemed at the option of the Company’s Board of Directors at any time. The Series A Preferred is redeemable based on the stated fair value of $5.00 per share. The Series A Preferred has no dividend rights and no rights to the undistributed earnings of the Company.

The closing of the sale and issuance of the Series B Shares occurred on October 1, 2020. Subject to shareholder approval, the Series B Shares automatically convert into fully paid and non-assessable shares of common stock at a conversion price equal to $14.37 per share.

Under the terms of the Subscription Agreement, the Conversion Shares will continue to be subject to the restrictions on transfer that expire on October 1, 2021. The Series B Shares contained a contingent beneficial conversion feature (“BCF”) that was recognized and accreted at its intrinsic value of $11,443 upon shareholder approval on December 10, 2020 and recognized in the Consolidated Statements of Shareholders’ Equity. The BCF is treated as a deduction from net loss to arrive at net loss attributable to common shareholders for the purposes of calculating earnings per share. See Note 5 for calculation of basic and diluted earnings per share. Common Stock In June 2008, the Board of Directors authorized 50,000 shares of common stock, par value $0.001 per share. The holders of Digimarc common stock are entitled to one vote for each share held of record on all matters submitted to a vote of its shareholders, including the election of directors.

The 2018 Plan provides for the grant of incentive and non-qualified stock options, stock appreciation rights, stock awards, restricted stock awards, restricted stock units, performance shares, performance units, and other stock or cash-based awards, which may be granted to officers, directors, employees, consultants, agents, advisors and independent contractors who provide services to the Company and its affiliated companies. The 2018 Plan authorizes the issuance of 1,000 shares of common stock. In addition, up to 770 shares of common stock subject to awards outstanding under the 2008 Plan became available for issuance under 2018 Plan to the extent that those shares cease to be subject to the awards (as a result of, for example, expiration, cancellation or forfeiture of the award). The shares authorized under the 2018 Plan are subject to adjustment in the event of a stock split, stock dividend, recapitalization or similar event. Shares issued under the 2018 Plan will consist of authorized and unissued shares or shares held by the Company as treasury shares. If an award granted under the 2018 Plan lapses, expires, terminates or is forfeited or surrendered without having been fully exercised or without the issuance of all the shares subject to the award, the shares covered by that award will again be available for issuance under the 2018 Plan. Shares that are (i) tendered by a participant or retained by the Company as payment for the purchase price of an award or to satisfy tax withholding obligations or (ii) covered by an award that is settled in cash, or in some manner that some or all of the shares covered by the award are not issued, will again be available for issuance under the 2018 Plan. In addition, awards granted as substitute awards in connection with acquisition transactions will not reduce the number of shares authorized for issuance under the 2018 Plan. As of December 31, 2020, under all of the Company’s stock-based compensation plans, an additional 807 shares remained available for future grants under the 2018 Plan.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Description of Business	Description of Business Digimarc Corporation (“Digimarc” or the “Company”), an Oregon corporation, is the inventor of a platform that enables a more efficient, reliable and economical means of automatic identification. The Digimarc Platform can apply a unique identifier to virtually all media objects—including product packaging, commercial print, audio and video—that can be automatically identified by an enabled ecosystem of industrial scanners, smartphones and other interfaces. These capabilities allow Digimarc and its partners to supply a wide range of solutions for retail and supply chain operations, consumer engagement, media management and security. The Digimarc Platform features three core capabilities for the identification, discovery and quality management of media. Digimarc Barcode integrates the identification function, which is a novel data carrier encoded into media in ways that are generally imperceptible to people, permitting the carrier to be repeated many times over the surface of the enhanced media. Digimarc Discover represents the discovery function, which is software for computing devices and network interfaces that recognize and decode indicia of the identity of media. These include, but are not limited to, Digimarc Barcodes, Quick Response Codes, Universal Product Codes, certain other GS1 approved one-dimensional codes and relevant contextual data. Digimarc Verify incorporates the quality management function, a suite of software tools used to inspect and verify that the identification and discovery of media are both accurate and effective. Together, these core capabilities enable organizations, application developers, and other solution providers to build new and improve existing automatic identification solutions.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Digimarc and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”) requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosure of contingent assets and liabilities. The Company’s accounting policies for revenue recognition require higher degrees of judgment than others in their application. Management bases its estimates on historical experience and on other assumptions that are believed to be reasonable in the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
Reclassifications	Reclassifications Certain prior period amounts in the accompanying consolidated financial statements and notes thereto have been reclassified to conform to current period presentation, including the reclassification of revenue and expense accounts to better align with the presentation provided by our peers in the software industry. These reclassifications had no material effect on the results of operations or financial position for any period presented.
Cash Equivalents	Cash Equivalents The Company considers all highly liquid marketable securities with original maturities of 90 days or less at the date of acquisition to be cash equivalents. Cash equivalents include money market securities, commercial paper and pre-refunded municipals totaling $18,568 and $10,436 at December 31, 2020 and 2019, respectively. Cash equivalents are carried at either cost or amortized cost depending on the type of security, which approximates fair value.
Marketable Securities	Marketable Securities The Company considers all investments with original maturities over 90 days that mature in less than one-year from the balance sheet date to be short-term marketable securities. Short-term marketable securities primarily include commercial paper, pre-refunded municipals and corporate notes. The Company’s marketable securities are classified as held-to-maturity and are reported at amortized cost, which approximates market value. A decline in the market value of any security below amortized cost that is deemed to be other-than-temporary results in a reduction in the carrying amount. The impairment is charged to earnings and a new cost basis for the security is established. To determine whether an impairment is other-than-temporary, the Company considers whether it has the ability and intent to hold the investment until a market price recovery and considers whether evidence indicating that the cost of the investment is recoverable outweighs evidence to the contrary. There have been no other-than-temporary impairments identified or recorded by the Company. Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to yield using a method that approximates the effective interest method. Under this method, dividend and interest income are recognized when earned.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Accounting Standards Codification (“ASC”) 820 “ Fair Value Measurements and Disclosures • Level 1—Pricing inputs are quoted prices available in active markets for identical investments as of the reporting date. • Level 2—Pricing inputs are quoted for similar investments, or inputs that are observable, either directly or indirectly, for substantially the full term through corroboration with observable market data. Level 2 includes investments valued at quoted prices adjusted for legal or contractual restrictions specific to these investments. • Level 3—Pricing inputs are unobservable for the investment; that is, the inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. The estimated fair values of the Company’s financial instruments, which include cash equivalents, accounts receivable, accounts payable and other accrued liabilities, approximate their carrying values due to the short-term nature of these instruments. The Company’s fair value hierarchy for its cash equivalents and marketable securities as of December 31, 2020 and 2019, respectively, was as follows: December 31, 2020 Level 1 Level 2 Level 3 Total Money market securities $ 10,988 $ — $ — $ 10,988 Commercial paper — 36,478 — 36,478 Pre-refunded municipals — 26,697 — 26,697 Corporate notes — 2,437 — 2,437 Total $ 10,988 $ 65,612 $ — $ 76,600 December 31, 2019 Level 1 Level 2 Level 3 Total Money market securities $ 746 $ — $ — $ 746 Commercial paper — 25,481 — 25,481 Corporate notes — 5,773 — 5,773 U.S. treasuries — 4,040 — 4,040 Total $ 746 $ 35,294 $ — $ 36,040 The fair value maturities of the Company’s cash equivalents and marketable securities as of December 31, 2020 are as follows: Maturities by Period Total Less 1 year 1-5 years 5 - 10 years More than 10 years Cash equivalents and marketable securities $ 76,600 $ 76,600 $ — $ — $ —
Concentrations of Business and Credit Risk	Concentrations of Business and Credit Risk A significant portion of the Company’s business depends on a limited number of large contracts. The loss of any large contract may result in loss of revenue and margin on a prospective basis. Financial instruments that potentially subject Digimarc to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, and accounts receivable. Digimarc places its cash and cash equivalents with major banks and financial institutions and at times deposits may exceed insured limits. Other than cash used for operating needs, which may include short-term marketable securities with the Company’s principal banks, Digimarc’s investment policy limits its credit exposure to any one financial institution or type of financial instrument by limiting the maximum of 5% of its cash equivalents and marketable securities or $1,000, whichever is greater, to be invested in any one issuer except for the U.S. government, U.S. federal agencies and U.S. backed securities, which have no limits, at the time of purchase. The Company’s investment policy also limits its credit exposure by limiting the maximum of 40% of its cash equivalents and marketable securities, or $15,000, whichever is greater, to be invested in any one industry category, (e.g., financial or energy industries), at the time of purchase. As a result, Digimarc’s credit risk associated with cash and cash equivalents and marketable securities is believed to be minimal.
Contingencies	Contingencies The Company evaluates all pending or threatened contingencies or commitments, if any, that are reasonably likely to have a material adverse effect on the Company’s operations or financial position. The Company assesses the probability of an adverse outcome and determines if it is remote, reasonably possible or probable as defined in accordance with ASC 450 “ Contingencies
Goodwill	Goodwill The Company tests goodwill for impairment annually and whenever events or changes in circumstances indicate that the carrying value may exceed the fair value, in accordance with ASC 350 “ Intangibles – Goodwill and Other
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company assesses long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, in accordance with ASC 360 “ Property, Plant and Equipment Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to future net undiscounted cash flows expected to be generated by the assets over their remaining useful life. If such assets are considered to be impaired, the impairment would be recognized in operating results at the amount by which the carrying amount of the assets exceeds the fair value of the assets. Fair value is determined based on discounted cash flows or appraised values, depending on the nature of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.
Research and Development	Research and Development Research and development costs are expensed as incurred in accordance with ASC 730 “ Research and Development
Software Development Costs	Software Development Costs Under ASC 985 “ Software
Patent Costs	Patent Costs Costs associated with the application and award of patents in the U.S. and various other countries are capitalized and amortized on a straight-line basis over the term of the patents as determined at award date, which varies depending on the pendency period of the application. Capitalized patent costs, also referred to as patent prosecution costs, include internal legal labor, professional legal fees, government filing fees and translation fees related to expanding the Company’s patent portfolio. Costs associated with the maintenance and annuity fees of patents are accounted for as prepaid assets at the time of payment and amortized over the shorter of the maintenance period or remaining life of the related patent.
Revenue Recognition	Revenue Recognition See Note 2 for detailed disclosures of the Company’s revenue recognition policy.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation in accordance with ASC 718 “ Compensation—Stock Compensation For stock option awards, the Company uses the Black-Scholes option pricing model as its method of valuation. The Company’s determination of the fair value on the date of grant (measurement date) is affected by its stock price as well as assumptions regarding a number of subjective variables. These variables include, but are not limited to, the expected life of the award, the Company’s expected stock price volatility over the term of the award, the risk-free interest rate and the expected dividend yield. For restricted stock awards which vest upon meeting a service condition , the Company uses the fair market value of the Company’s common stock on the date of the grant (measurement date) as its method of valuation . For performance restricted stock awards which vest upon meeting both a market condition and a service condition, the Company uses the Monte Carlo Simulation model as its method of valuation. The Company’s determination of the fair value on the date of grant (measurement date) is affected by its stock price as well as assumptions regarding a number of subjective variables. These variables include, but are not limited to, the expected stock price volatility over the term of the award and the risk-free interest rate. Although the fair value of stock-based awards is determined in accordance with ASC 718 and Staff Accounting Bulletin (“SAB”) No. 107 “ Shared-Based Payment ”
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with ASC 740 “ Income Taxes The Company records valuation allowances on deferred tax assets if, based on available evidence, it is more-likely-than-not that all or some portion of the assets will not be realized. The Company is subject to income taxes within the U.S. and other countries, and, in the ordinary course of business, there are transactions and calculations where the ultimate tax determination is uncertain. The Company reports a liability (or contra asset) for unrecognized tax benefits resulting from uncertain tax positions taken (or expected to be taken) on a tax return. The Company recognizes interest and penalties, if any, related to the unrecognized tax benefits in income tax expense.
Accounting Pronouncements Issued But Not Yet Adopted	Accounting Pronouncements Issued But Not Yet Adopted In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, “ Financial Instruments - Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments In December 201 9 , the FASB issued ASU No. 201 9 - 1 2, “ Income Taxes ( ASC 740) Simplifying the Accounting for Income Taxes ,” that removes certain exceptions to the general principles and also improves consistent application of and simplify generally accepted accounting principles . The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020 . Early adoption is permitted. The Company does not expect the impact of the adoption of this standard to have a material impact on the Company’s financial condition, results of operations and disclosures.
Earnings Per Share	The Company calculates basic and diluted earnings per common share in accordance with ASC 260 “ Earnings Per Share
