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 a pioneer of digital watermarking solutions, which enable a more efficient, reliable and economical means of automatic identification. Digimarc technology can be used to apply a unique digital identity to virtually all media objects, including product packaging, commercial print, audio and video. These digital identities can be automatically identified by an enabled ecosystem of industrial scanners, smartphones and other interfaces. The technology features: • Digimarc watermarks: a data carrier that can provide a unique digital identity to media objects and is generally visibly imperceptible to people and therefore can be repeated many times over the surface of media objects. • Digimarc Discover: a software program for computing devices and network interfaces that recognizes and decodes digital identities applied to media objects. These digital identities can be applied to media objects using Digimarc watermarks, quick response codes and universal product codes, among other types of codes. • Digimarc Verify: a suite of software tools used to inspect and verify that the digital identity applied via Digimarc watermarks to media objects are 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. D igimarc acquired EVRYTHNG Limited (“EVRYTHNG”) on January 3, 2022. The financial results of EVRYTHNG will be consolidated with Digimarc’s financial results prospectively. See Note 16 for information related to the EVRYTHNG acquisition. 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 by major target market in Note 2. 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 $2,478 and $18,568 at December 31, 2021 and 2020, 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, corporate notes, federal agency notes and pre-refunded municipals. 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 The Company’s fair value hierarchy for its cash equivalents and marketable securities as of December 31, 2021 and 2020, respectively, was as follows: December 31, 2021 Level 1 Level 2 Level 3 Total Money market securities $ 2,478 $ — $ — $ 2,478 Commercial paper — 13,382 — 13,382 Corporate notes — 9,585 — 9,585 Federal agency notes — 3,799 — 3,799 Pre-refunded municipals — 1,063 — 1,063 Total $ 2,478 $ 27,829 $ — $ 30,307 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 The fair value maturities of the Company’s cash equivalents and marketable securities as of December 31, 2021 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 $ 30,307 $ 22,015 $ 8,292 $ — $ — The estimated fair values of the Company’s financial instruments, which include accounts receivable, loan receivable from related party, accounts payable and other accrued liabilities, approximate their carrying values due to the short-term nature of these instruments. 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 the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, and accounts receivable. The Company 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, the Company’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, the Company’s credit risk associated with cash and cash equivalents and marketable securities is believed to be minimal. The Company manages credit risk on accounts receivable by evaluating a customer’s credit worthiness before extending any significant amount of credit. There is a significant concentration of accounts receivable at vary times from our two largest customers. Both customers have significant financial means and a history of paying their invoices timely. The Company does not have a history of significant bad debt write-offs. As a result, the Company’s credit risk associated with accounts receivable is believed to be low. 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 options, 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 and restricted stock units that 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 units that 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. Liquidity Under the rules of ASC Subtopic 205-40 “ Presentation of Financial Statements-Going Concern” (“ASC 205-40”), The Company plans, as necessary, to secure additional capital in the future through increased revenue, exercise of the EVRYTHNG warrants, partnerships, collaborations, equity or debt financings, or other sources to carry out the Company’s planned business activities. If additional capital is not available when required, the Company may need to take steps to contain costs until such funding is received. Accounting Pronouncements Adopted In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, “ Income Taxes (ASC 740) Simplifying the Accounting for Income Taxes The adoption of this standard did not have a material impact on the Company’s financial condition, results of operations and disclosures . In October 2021, the FASB issued ASU No. 2021-08, “ Business Combination (ASC 805): Accounting for Contract Assets and Liabilities from Contracts with Customers he Company is currently evaluating the impact of adopting this standard on the Company’s financial condition, results of operations and disclosures in relation to the recent acquisition of EVRYTHNG.

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 and, to a lesser extent, professional services. The majority of software development contracts are structured as time and materials consulting agreements. Revenue for services is generally recognized 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 or sale 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. C ustomer 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, 2021 2020 Government Service $ 13,198 $ 13,263 Subscription 1,200 1,400 Total Government 14,398 14,663 Commercial Service $ 1,808 $ 618 Subscription 10,314 8,709 Total Commercial 12,122 9,327 Total $ 26,520 $ 23,990 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.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
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 options, restricted stock, restricted stock units, and performance restricted stock units. 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, 2021 2020 Stock price $ — $ 15.36 Expected life (years) — 3.25 Expected volatility — 70.91 % Risk-free interest rate — 0.25 % Expected dividend yield — 0 % There were no stock options granted during the year ended December 31, 2021 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. There were no RSUs granted during the year ended December 31, 2021. Performance Restricted Stock Units The fair value of performance restricted stock unit (“PRSU”) awards, which vest upon meeting 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.

Bruce Davis notified the Company of his intention to retire as the Company’s President and Chief Executive Officer and as Chairman and a member of the Board of Directors effective April 12, 2021 (the “Transition Date”). In connection with his retirement, the Company entered into a Separation Agreement and General Release with Mr. Davis (the “Separation Agreement”), dated April 12, 2021. Pursuant to the Separation Agreement, Mr. Davis agreed to release certain claims he may have against the Company and other released parties, and Mr. Davis’s stock options, restricted stock and RSUs that vest solely based on continued service, and PRSUs that were earned and remained subject to time-based vesting, immediately vested with respect to the number of shares that would have vested if Mr. Davis’s employment had continued for an additional twenty-four months from the Transition Date, and his right to exercise vested stock options will expire on the earliest of (i) twenty-eight months from the Transition Date, (ii) the latest date the particular stock option could have expired by its original terms under any circumstances, or (iii) the tenth anniversary of the original date of grant of the particular stock option. The terms of the Separation Agreement resulted in the acceleration of vesting for 137 stock options, 30 RSUs, and 82 PRSUs and the forfeiture of 35 stock options, 15 RSUs, and 42 PRSUs. The terms of the Separation Agreement also resulted in a modification to all of Mr. Davis’s outstanding stock options, as the expiration date for exercise of the options was extended beyond the original terms of the options, and 21 PRSUs were modified to provide for accelerated vesting. In accordance with ASC 718, the Company calculated the fair value of the modified stock options and PRSUs and calculated the fair value of the original stock options and PRSUs immediately before the modification. The Company recorded additional stock-based compensation expense of $1,926 upon modification of these awards during the second quarter ended June 30, 2021. The Company incurred a total of $3,990 of stock-based compensation expense, including the impact of the modified awards noted above, during the second quarter ended June 30, 2021, associated with the Separation Agreement.

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 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.

Subsequent Events	(16) Subsequent Events EVRYTHNG Acquisition On January 3, 2022, the Company closed on its acquisition of EVRYTHNG pursuant to the Share Purchase Agreement (“Purchase Agreement”) entered into on November 15, 2021. Upon closing, EVRYTHNG became a wholly owned subsidiary of the Company. The Company acquired all outstanding shares of EVRYTHNG’s share capital in exchange for aggregate initial consideration consisting of 772 shares of common stock of the Company and warrants to purchase 231 shares of common stock of the Company. The number of warrants issued was determined based on there being approximately $8,500 of closing costs, which includes EVRYTHNG’s outstanding indebtedness, transaction expenses and certain other liabilities, net of EVRYTHNG’s cash on hand at closing. The Company paid $6,931 of the estimated closing costs in January 2022. A portion of the initial consideration was held back by the Company to secure any post-closing adjustments to the initial consideration and the indemnification obligations of the sellers. The warrants have a per share exercise price of $36.56 and may only be exercised by payment of the exercise price in cash. The number of shares of common stock underlying the warrants and the exercise price of the warrants are subject to adjustment upon the occurrence of certain specified events, including subdivisions and combinations of the Company’s common stock. The warrants will expire on March 27, 2022. Under the terms of the Purchase Agreement, the Company filed a Registration Statement on Form S-3 with the SEC on January 19, 2022, that became effective on January 28, 2022, covering the resale of the common shares issued and to be issued as consideration to the sellers.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Description of Business	Description of Business Digimarc Corporation (“Digimarc” or the “Company”), an Oregon corporation, is a pioneer of digital watermarking solutions, which enable a more efficient, reliable and economical means of automatic identification. Digimarc technology can be used to apply a unique digital identity to virtually all media objects, including product packaging, commercial print, audio and video. These digital identities can be automatically identified by an enabled ecosystem of industrial scanners, smartphones and other interfaces. The technology features: • Digimarc watermarks: a data carrier that can provide a unique digital identity to media objects and is generally visibly imperceptible to people and therefore can be repeated many times over the surface of media objects. • Digimarc Discover: a software program for computing devices and network interfaces that recognizes and decodes digital identities applied to media objects. These digital identities can be applied to media objects using Digimarc watermarks, quick response codes and universal product codes, among other types of codes. • Digimarc Verify: a suite of software tools used to inspect and verify that the digital identity applied via Digimarc watermarks to media objects are 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. D igimarc acquired EVRYTHNG Limited (“EVRYTHNG”) on January 3, 2022. The financial results of EVRYTHNG will be consolidated with Digimarc’s financial results prospectively. See Note 16 for information related to the EVRYTHNG acquisition.
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 by major target market in Note 2. 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 $2,478 and $18,568 at December 31, 2021 and 2020, 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, corporate notes, federal agency notes and pre-refunded municipals. 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 The Company’s fair value hierarchy for its cash equivalents and marketable securities as of December 31, 2021 and 2020, respectively, was as follows: December 31, 2021 Level 1 Level 2 Level 3 Total Money market securities $ 2,478 $ — $ — $ 2,478 Commercial paper — 13,382 — 13,382 Corporate notes — 9,585 — 9,585 Federal agency notes — 3,799 — 3,799 Pre-refunded municipals — 1,063 — 1,063 Total $ 2,478 $ 27,829 $ — $ 30,307 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 The fair value maturities of the Company’s cash equivalents and marketable securities as of December 31, 2021 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 $ 30,307 $ 22,015 $ 8,292 $ — $ —
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 the Company to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, and accounts receivable. The Company 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, the Company’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, the Company’s credit risk associated with cash and cash equivalents and marketable securities is believed to be minimal. The Company manages credit risk on accounts receivable by evaluating a customer’s credit worthiness before extending any significant amount of credit. There is a significant concentration of accounts receivable at vary times from our two largest customers. Both customers have significant financial means and a history of paying their invoices timely. The Company does not have a history of significant bad debt write-offs. As a result, the Company’s credit risk associated with accounts receivable is believed to be low.
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 options, 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 and restricted stock units that 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 units that 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.
Liquidity	Liquidity Under the rules of ASC Subtopic 205-40 “ Presentation of Financial Statements-Going Concern” (“ASC 205-40”), The Company plans, as necessary, to secure additional capital in the future through increased revenue, exercise of the EVRYTHNG warrants, partnerships, collaborations, equity or debt financings, or other sources to carry out the Company’s planned business activities. If additional capital is not available when required, the Company may need to take steps to contain costs until such funding is received.
