Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Recent Accounting Developments	Description of Business and Recent Accounting Developments Description and Organization Clear Secure, Inc. (the “Company” and together with its consolidated subsidiaries, “CLEAR,” “we,” “us,” “our”) is a holding company and its principal asset is the controlling equity interest in Alclear Holdings, LLC (“Alclear”). Alclear was formed as a Delaware limited liability company on January 21, 2010 and operates under the terms of the Amended and Restated Operating Agreement dated June 29, 2021 (the “Operating Agreement”). As the sole managing member of Alclear, the Company operates and controls all of the business and affairs of Alclear, and through Alclear and its subsidiaries, conducts the Company’s business. The Company operates a secure identity platform under the brand name CLEAR primarily in the United States. CLEAR's current offerings include: CLEAR Plus, a consumer aviation subscription service, which enables access to predictable and fast experiences through dedicated entry lanes in airport security checkpoints nationwide; the flagship CLEAR App including Home to Gate and Health Pass; and Reserve powered by CLEAR, our virtual queuing technology that enables customers to manage lines. Reorganization and Initial Public Offering On June 29, 2021, prior to the completion of the initial public offering (“IPO”) of the Company’s shares of Class A common stock, $0.00001 par value per share (the “Class A Common Stock”), the Company, Alclear and its subsidiaries consummated an internal reorganization (the “Reorganization”) which resulted in the following: • Clear Secure, Inc. became the sole managing member of Alclear. • The certificate of incorporation of Clear Secure, Inc. was amended and restated to authorize the Company to issue four classes of Common Stock: Class A Common Stock, Class B common stock, $0.00001 par value per share (the “Class B Common Stock”), Class C common stock, $0.00001 par value per share (the “Class C Common Stock”) and Class D common stock, $0.00001 par value per share (the “Class D Common Stock” and, together with the Class A Common Stock, Class B Common Stock and Class C Common Stock, collectively, “Common Stock”). The Class A Common Stock and Class C Common Stock provide holders with one vote per share on all matters submitted to a vote of stockholders, and the Class B Common Stock and Class D Common Stock provide holders with twenty votes per share on all matters submitted to a vote of stockholders. The holders of Class C Common Stock and Class D Common Stock do not have any of the economic rights (including rights to dividends and distributions upon liquidation) provided to holders of Class A Common Stock and Class B Common Stock. • All Alclear’s outstanding equity interests (including Class A units, Class B units and profit units) were reclassified into Alclear non-voting common units (“Alclear Units”). The number of Alclear Units issued to each member of Alclear was determined based on a hypothetical liquidation of Alclear and the initial public offering price per share of the Company’s Class A Common Stock in the IPO. Certain members exchanged their Alclear Units for an equal number of Class A Common Stock. • Alclear Investments, LLC, an entity controlled by Caryn Seidman-Becker, the Chair of our Board, our Co-Founder and our Chief Executive Officer, and Alclear Investments II, LLC, an entity controlled by Kenneth Cornick, our Co-Founder, President and Chief Financial Officer, contributed a portion of their Alclear Units to us in exchange for Class B Common Stock. • The remaining members of Alclear, including Alclear Investments, LLC and Alclear Investments II, LLC (“Alclear members”) subscribed for and purchased shares of the Company’s Class C Common Stock and Class D Common Stock at a purchase price of $0.00001 per share and in an amount equal to the number of Alclear Units held by such members. • The Company entered into a Tax Receivable Agreement (“TRA”) which generally provides for payment by the Company to the remaining members of Alclear, the “TRA Holders,” of 85% of the net cash savings, if any, in U.S. federal, state and local income tax and franchise tax that the Company actually realizes or is deemed to realize in certain circumstances. The Company will retain the benefit of the remaining 15% of these net cash savings. • Alclear is treated as a partnership for U.S. federal income tax purposes and, as such, is itself generally not subject to U.S. federal income tax under current U.S. tax laws. Clear Secure, Inc, as a member of Alclear, will be required to take into account for U.S. federal income tax purposes its distributive share of the items of income, gain, loss and deduction of Alclear. As the Reorganization is considered a transaction between entities under common control, the condensed consolidated financial statements for periods prior to the IPO and Reorganization have been adjusted to combine the previously separate entities for presentation purposes. Prior to the Reorganization, Clear Secure, Inc. had not engaged in any business or other activities, except in connection with its formation. On July 2, 2021, the Company completed the IPO of its Class A Common Stock. In the IPO, the Company sold an aggregate of 15,180,000 shares of Class A Common Stock, $0.00001 par value per share, at an offering price of $31 per share including as a result of the underwriters exercising their option to purchase up to 1,980,000 shares of Class A Common Stock. As a result, Clear Secure, Inc. received net proceeds from the IPO of approximately $445,875 after deducting underwriting discounts and commissions. As a result of the IPO, the Company contributed the net IPO Proceeds to Alclear in exchange for 15,180,000 Alclear Units. For the three months ended March 31, 2022, and the year ended December 31, 2021, the Company incurred $297 and $9,038 of issuance related costs as a result of the IPO, respectively, that were recorded within additional paid in capital within the condensed consolidated balance sheets. Recently Adopted Accounting Pronouncements Emerging Growth Company Status The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies, until the earlier of the date that it (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. Leases As of January 1, 2022, the Company adopted ASU No. 2016-02, Leases (Topic 842) (ASU 2016-02) on a modified retrospective basis with respect to all lease arrangements that existed as of the adoption date. Refer to Note 8 for further details. Current Expected Credit Losses As of January 1, 2022, the Company adopted, ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). There was no significant impact within the condensed consolidated financial statements as a result of adoption. Business Combinations In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). ASU 2021-08 addresses inconsistency related to the recognition and measurement of contract assets and contract liabilities acquired in a business combination. ASU 2021-08 requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination as if it had originated the contracts, in accordance with Topic 606, Revenue from Contracts with Customers. The guidance is effective for fiscal years beginning after December 15, 2022 and interim periods within those fiscal years. Early adoption of the amendments is permitted and an entity that early adopts should apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period of early application and (2) prospectively to all business combinations that occur on or after the date of initial application. The Company continues to evaluate the impact of this standard on its consolidated financial statements. Other Recent Accounting Pronouncements Adopted and New Standards and Interpretations Not Yet Effective Other than the items discussed above, there are no standards issued by the FASB and adopted by the Company effective as of January 1, 2022 that had a material impact on the Company’s condensed consolidated financial statements. Additionally, there are no standards that are not yet effective that are expected to have a material impact on the Company’s condensed consolidated financial statements.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K (the “Form 10-K). Preparing financial statements requires management to make estimates and assumptions that affect the amounts that are reported in the financial statements and the accompanying disclosures, including the vesting of share-based and other deferred compensation plan awards. Although these estimates are based on management’s knowledge of current events and actions that the Company may undertake in the future, actual results may differ materially from the estimates. Intercompany transactions and balances are eliminated upon consolidation. The Company has one operating and reportable segment, which includes the operations of the businesses acquired during the year ended December 31, 2021. Items included in the financial statements of each of the Company’s consolidated entities are measured using the currency of the primary economic environment in which the entity operates. The condensed consolidated financial statements are presented in US Dollars, which is the Company’s reporting currency. Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at period-end exchange rates are recognized in other income (expense), net within the condensed consolidated statement of operations. The results and financial position of all the Company entities that have a functional currency different from the Company's reporting currency are translated into US Dollars as follows: •Assets and liabilities are translated at the closing rate at the reporting date; •Income and expenses for each statement of operation are translated at average exchange rates; and •All resulting exchange differences are recognized in other comprehensive loss.

Business Combination and Asset Acquisition [Abstract]
Business Combinations	3. Business Combinations During the year ended December 31, 2021, the Company completed two acquisitions, which are described further below. Both acquisitions were accounted for as business combinations. The goodwill for both acquisitions represents the future economic benefits expected to arise from other intangible assets acquired that do not qualify for separate recognition, including expected future synergies and technical expertise of the acquired workforce For both acquisitions, the intangible assets acquired primarily relate to existing technology, customer relationships and brand names. The useful life of these intangible assets range from 3-11 years. The Company valued the intangible assets using the relief from royalty method and the multi-period excess earnings method, both under the income approach. For both acquisitions, the Company’s allocation of purchase price was based upon valuations performed to determine the fair value of the net assets as of the acquisition date and is therefore subject to adjustments for up to one year after the closing date of the acquisition to reflect final valuations. As a result of the acquisitions, the Company recognized $1,391 of acquisition-related costs during the year ended December 31, 2021, which are recorded in general and administrative within the condensed consolidated statement of operations. Revenues and operating loss related to these acquisitions for the three months ended March 31, 2022 were not material to the condensed consolidated financial statements. Refer below for additional details on the acquisitions. Whyline, Inc. On December 29, 2021, Alclear acquired 100% of Whyline, Inc., a provider of virtual queuing and appointment technology that the Company operates under the product name, Reserve powered by CLEAR. The cash consideration of $67,500 was transferred upon closing, and there was an estimated contingent consideration of $100. The acquisition was accounted for as a business combination. In the Company’s preliminary allocation of the purchase consideration, $54,792 was initially recorded as goodwill, $16,601 as acquired intangible assets, $3,792 as net deferred tax liabilities and $99 as net operating assets on the condensed consolidated balance sheets. None of the goodwill recognized is expected to be deductible for tax purposes. During the three months ended March 31, 2022, and in accordance with the election described above, the Company recorded a $1,411 decrease to goodwill, a $2,100 increase to acquired intangible assets and a $689 increase to deferred tax liabilities. The accounting for the acquisition is not complete as the valuation for certain acquired assets and liabilities have not been finalized. These final valuations of the assets and liabilities could have a material impact on the preliminary purchase price allocation disclosed above. In conjunction with the acquisition, the Company entered into an agreement to issue shares of Class A Common Stock upon satisfaction of terms related to the contingent consideration and remuneration for post-combination services (collectively referred to as the “Earn-Out”). The first tranche will be settled upon the achievement of specified operating metrics during the twelve month period ended December 31, 2022. The second tranche will be settled upon the achievement of specified operating metrics during the twelve month period ended December 31, 2023. The maximum settlement of the contingent consideration is $6,666, which is not subject to the satisfaction of service based criteria. For remuneration for post-combination services, there is a maximum settlement of $13,334 that is based on performance and service based criteria being met; portions of these amounts will automatically be forfeited if the employment of specified individuals terminates prior to the end of the Earn-Out period. To the extent probable, the post-combination remuneration amount is allocated evenly to the 2022 operating metrics and 2023 operating metrics targets. The Company has not recorded any compensation expense for three months ended March 31, 2022 as the performance criteria is not probable. The estimated fair value of the contingent consideration is determined using an option pricing model and is based upon available information and certain assumptions, known as of the reporting date, which management believes are reasonable. Any differences in the actual contingent consideration liability compared to the fair value as of the previous reporting date will be recorded within general and administrative within the condensed consolidated statements of operations. The Company has not recorded any fair value adjustments on its contingent consideration for three months ended March 31, 2022 as there was no change in assumptions. The final number of shares to be issued upon satisfaction of the Earn-Out will be based on the average of the volume-weighted average trading price on the New York Stock Exchange for one share of Class A Common Stock for each of the 30 full trading days ending on and including the full trading day immediately prior to the applicable Earn-Out payment date. Atlas Certified, LLC. On December 30, 2021, Alclear acquired certain assets of Atlas Certified, LLC, which provides an automated solution to verify professional licenses and certification data across industries by communicating with certifying organizations for on demand, current and trusted data. The fair value of the purchase consideration was $9,000. The acquisition was accounted for as a business combination. In the Company’s preliminary allocation of the purchase consideration $5,000 was recorded as goodwill and $4,000 as acquired intangible assets on the condensed consolidated balance sheets. The goodwill recognized is expected to be deductible for tax purposes. During the three months ended March 31, 2022, there were no adjustments to the preliminary allocation. The accounting for the acquisition is not complete as the valuation for certain acquired assets and liabilities have not been finalized. These final valuations of the assets and liabilities could have a material impact on the preliminary purchase price allocation disclosed above.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company values its available-for-sale securities and certain liabilities based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability in fair value measurements, a fair value hierarchy that prioritizes observable and unobservable inputs is used to measure fair value into three broad levels, which are described below: Level 1 – Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2 – Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in inactive markets or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated with observable market data. Level 3 – Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs to the extent possible. In addition, the Company considers counterparty credit risk in its assessment of fair value. The asset or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. The following is a description of the valuation methodologies used for assets and liabilities measured at fair value. Corporate bonds – Valued at the closing price reported on the active market on which the individual securities, all of which have counterparts with high credit ratings, are traded. Commercial paper – Value is based on yields currently available on comparable securities of issuers with similar credit ratings. Money market funds – Valued at the net asset value (“NAV”) of units of a collective fund. The NAV is used as a practical expedient to estimate fair value. This practical expedient is not used when it is determined to be probable that the fund will sell the investment for an amount different than the reported NAV. Contingent consideration – Valued at fair value using a simulation of targeted outcomes. Warrant liabilities – The Company had certain outstanding warrant liabilities prior to the Reorganization. These were valued based on significant inputs not observed in the market and, thus, represented a Level 3 measurement. The Company estimated the fair value of the liability using the Black-Scholes option pricing model and the change in fair value was recognized in general and administrative expenses. Refer to Note 13 for further information. The contractual maturities of investments classified as marketable securities are as follows: March 31, December 31, Due within 1 year $ 301,021 $ 288,036 Total marketable securities $ 301,021 $ 288,036 Fair Value as of March 31, 2022 Level 1 Level 2 Level 3 Total Commercial paper $ — $ 117,501 $ — $ 117,501 U.S. Treasuries 89,952 — — 89,952 Corporate bonds — 124,092 — 124,092 Total assets in the fair value hierarchy 89,952 241,593 — 331,545 Money market funds measured at NAV (a) — — — 2,808 Total assets at fair value $ 89,952 $ 241,593 $ — $ 334,353 Contingent consideration — — (100) (100) Total liabilities at fair value $ — $ — $ (100) $ (100) Fair Value as of December 31, 2021 Level 1 Level 2 Level 3 Total Commercial paper $ — $ 128,867 $ — $ 128,867 U.S. Treasuries 82,472 — — 82,472 Corporate bonds — 114,965 — 114,965 Total assets in the fair value hierarchy 82,472 243,832 — 326,304 Money market funds measured at NAV (a) — — — 8,924 Total assets at fair value $ 82,472 $ 243,832 $ — $ 335,228 Contingent consideration — — $ (100) (100) Total liabilities at fair value $ — $ — $ (100) $ (100) ____________________________ (a) Certain money market funds that were measured at NAV per share (or its equivalent) have not been classified in the fair value hierarchy.

Lessee Disclosure [Abstract]
Leases	Leases As discussed in Note 2, on January 1, 2022, the Company adopted the new accounting standard ASC 842, Leases, using the modified retrospective method. As a result, and as permitted by the standard, the Company has not updated financial information or related disclosures under ASC 842 for, periods prior to January 1, 2022. Upon adoption, the Company recognized $25,346 of right of use (“ROU”) assets, $29,139 of lease liabilities and derecognized $3,793 of deferred rent on the condensed consolidated balance sheets. The short term portion of the operating lease liabilities is included within accrued liabilities and the long term portion is included within other long term liabilities on the condensed consolidated balance sheets. The Company has entered into agreements to lease certain office spaces. These leases require monthly lease payments that may be subject to annual increases throughout the lease term. Certain of these leases also include renewal options at the election of the Company to renew or extend the lease for an additional three years. Additionally, certain of these leases contain termination options. These optional periods have not been considered in the determination of the ROU assets or lease liabilities as the Company did not consider it reasonably certain it would exercise the options. The Company performed evaluations of its contracts and determined it only has operating leases. The lease terms are between 1 and 12 years. Most of the Company’s lease agreements require payment of certain operating expenses in addition to base rent, such as taxes, insurance and maintenance costs. As allowed under ASC 842, the Company considers these as non-lease components and has elected to exclude these components from the measurement of its lease liabilities. The Company has also elected to apply the recognition requirement of ASC 842 to leases with a term of 12 months or less for all classes of assets. The Company has elected to utilize the following practical expedients available under the transition guidance in ASC 842: • The Company did not reassess whether any expired or existing contracts are or contain leases; • The Company did not reassess the lease classification for any expired or existing leases; and • The Company did not reassess initial direct costs for any existing leases. The Company did not elect the practical expedient available under the transition guidance in ASC 842 to use hindsight in determining the lease term and in assessing impairment of the Company’s ROU assets The Company determines if an arrangement is a lease at inception and recognizes ROU assets and lease liabilities upon commencement. 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. The classification of the Company's leases as operating or finance leases along with the initial measurement and recognition of the associated ROU assets and lease liabilities is performed at the lease commencement date. The measurement of lease liabilities is based on the present value of future lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of future lease payments. The ROU asset is based on the measurement of the lease liability and also includes any lease payments made prior to or on lease commencement and excludes lease incentives and initial direct costs incurred, as applicable. Rent expense for the Company's operating leases is recognized on a straight-line basis over the lease term. The Company has an additional operating lease for real estate space to house the Company’s corporate headquarters. The lease agreement provides for a commencement on the later of October 1, 2022 or the date on which the landlord delivers possession of the premises with certain agreed upon completed improvements to be made by the landlord. The term of the lease is fifteen eighteen Below is a reconciliation of the amounts reported on the condensed consolidated balance sheets with respect to the Company’s operating leases: March 31, 2022 $ 3,453 2023 3,729 2024 4,402 2025 4,478 2026 4,478 Thereafter 12,868 Total future operating lease payments 33,408 Less: imputed interest (5,115) Lease liabilities, current 3,338 Lease liabilities, non-current 24,955 Total lease liabilities $ 28,293 As of March 31, 2022, the weighted-average incremental borrowing rate applied to lease liabilities at the date of adoption was 4.3%. Additionally, the weighted-average remaining lease term was 7.7 years. Total operating lease expense recognized on the condensed consolidated statements of operations for the three months ended March 31, 2022 was $1,035. Cash paid for amounts included in the measurement of operating lease liabilities for the three months ended March 31, 2022 was $1,155.

Equity [Abstract]
Warrants	Warrants Historically, Alclear issued warrants for their holders to purchase shares of Class B redeemable capital units. These warrants were generally subject to performance-based vesting criteria, such as criteria related to new customer enrollments and technological innovations. The Company recognizes the expense for those warrants expected to vest on a straight-line basis over the requisite service period of the warrants, which generally ranges from three months to six years. For warrants that vest upon issuance, the entire cost is expensed immediately. As of December 31, 2020, Alclear had 658,382 equity warrants outstanding at a weighted-average exercise price of $222.15 and 70,000 liability warrants outstanding at a weighted-average exercise price of $36.74. Prior to the Reorganization, in 2021, Alclear issued the following warrants for Class B redeemable capital units as follows: Number of Units Weighted-average exercise price Liability awards 1,000 $ 1.00 Equity awards 114,797 $ 194.85 The fair values of warrants granted in 2021 were estimated based on the Black-Scholes option pricing model using the weighted-average significant unobservable inputs (Level 3 inputs) as follows: 2021 Risk-free interest rate 0.36% - 0.92% Exercise price $1.00-$290.00 Expected term 3-5 years Expected volatility 45.0% - 50.8% The 114,797 equity classified warrants issued during 2021 had a weighted average grant date fair value per warrant of $287.55. Prior to the Reorganization, certain warrant holders exercised their warrants for Class B redeemable capital units as follows: Number of Warrants Weighted-average exercise price Liability awards 70,000 $ 36.74 Equity awards 3,400 $ 1.00 On the date of exercise, the Company recognized a fair value adjustment to the outstanding liability classified warrants which was estimated based on a Black-Scholes option pricing model using the weighted-average significant unobservable inputs (Level 3 inputs) as follows: Risk-free interest rate 0.16% -0.19% Exercise price $1.00- $36.74 Expected term 2-3 years Expected volatility 35.1% - 45.0% Subsequent to the Reorganization, there were no unvested warrants classified as liability awards. As part of the Reorganization, the remaining Alclear warrants were either exchanged for Clear Secure, Inc. warrants representing the right to receive Class A Common Stock or remained at Alclear and continue to be exercisable for Alclear Units. The exchange was completed at an approximate 19.98 per unit ratio, using a cashless exercise conversion method. The Clear Secure, Inc. warrants are subject to the same vesting terms as applied to Alclear warrants and maintained the same fair value immediately before and after the exchange of the warrants. As such, there was no additional expense that was recorded as a result of the exchange of the warrants. In December 2021, certain warrant holders exercised 2,000,000 vested warrants with an intrinsic value of $54,120. In January 2022, the same warrant holders exercised 1,207,932 vested warrants with an intrinsic value of $32,457. These exercises resulted in the Company issuing shares of its Class A Common Stock and were completed in a cashless transaction. The following warrants remained outstanding as of March 31, 2022: Classification Number of Warrants Weighted-Average Exercise Price Weighted average Remaining Contractual Term (years) Exercisable for Class A Common Stock Equity awards 4,466,571 $ 0.01 0.73 Exercisable for Alclear Units Equity awards 968,043 $ 0.01 2.46 As of March 31, 2022, there were no vested warrants that were exercisable for Class A Common Stock. As of March 31, 2022, 194,108 warrants were vested and exercisable for Alclear Units with an intrinsic value of $5,215. The balance of the outstanding warrants are subject to certain performance based vesting criteria which the Company evaluates at each reporting period to determine the likelihood of achievement. Based on the likelihood of achievement of the vesting criteria, as of March 31, 2022 the Company estimated unrecognized warrant expense is $322. The Company recorded the following within general and administrative expense in the condensed consolidated statements of operations: Three Months Ended March 31, 2022 March 31, 2021 Liability awards $ — $ 1,893 Equity awards 70 281 Total $ 70 $ 2,174

Stockholders' Equity Note [Abstract]
Stockholder's Equity	Stockholders’ Equity Members’ Equity As a result of the Reorganization, members’ equity was $0 as of December 31, 2021. Additionally prior to the Reorganization, the Company had 21,042 authorized and 0 issued and outstanding Class C Capital Units, which were granted to employees as part of the Company’s annual compensation process. Prior to the Reorganization, Alclear also had 27 classes of nonvoting, non-capital units, of which 16 were issued as equity-based compensation and reflects equity-based compensation recorded for units granted and expected to vest based on the probability of achieving performance-based vesting conditions. From time to time, Alclear repurchased vested profit units and, to the extent the amount paid for profit units repurchased was in excess of the fair value, such excess was recorded in accumulated deficit. Prior to the Reorganization, during 2021, the Company repurchased 31,972 profit units for a total repurchase of $8,259. Since such repurchases were at amounts that exceeded the then fair value of the units, the Company recorded expense of $712 for the three months ended March 31, 2021. $697 was recorded within general and administrative expense and $15 within research and development within the condensed consolidated statements of operations. 1,868,322 profit units were authorized, issued and outstanding at December 31, 2020. All profit units were converted in conjunction with the Reorganization. Common Stock As discussed in Note 1, upon the Reorganization, the Company issued 59,240,306 shares of Class A Common Stock and 1,042,234 shares of Class B Common Stock in exchange for an equivalent amount of Alclear Units. In addition, Alclear members purchased 44,598,167 shares of Class C Common stock and Alclear Investments, LLC and Alclear Investments II, LLC collectively purchased 26,709,821 shares of Class D Common stock equal to the number of Alclear Units held by the members of Alclear (“Alclear Members”). As part of the IPO, the Company issued an additional 15,180,000 shares of Class A Common Stock on July 2, 2021. Treasury Stock The Company does not have a share repurchase program. The Company’s treasury stock consists of forfeited Restricted Stock Awards that are legally issued shares held by the Company that can be utilized to settle equity-based compensation awards issued by the Company and is recorded at par value. These shares are excluded from the calculation of the non-controlling interest ownership percentage. Non-Controlling Interest The non-controlling interest balance represents the economic interest in Alclear held by the founders and members of Alclear. The following table summarizes the ownership of Alclear Units as of March 31, 2022: Alclear Units Ownership Percentage Alclear Units held by post-reorganization members 43,386,797 29.21 % Alclear Units held by Alclear Investments, LLC and Alclear Investments II, LLC 26,705,315 17.98 % Total 70,092,112 47.19 % The non-controlling interest holders have the right to exchange Alclear Units, together with a corresponding number of shares of Class C Common Stock for Class A Common Stock or Class D Common Stock for Class B Common Stock. As such, exchanges by non-controlling interest holders will result in a change in ownership and reduce the amount recorded as non-controlling interest and increase Class A Common Stock or B Common Stock and additional paid-in-capital for the Company. Upon the issuance of shares Class A Common Stock or B Common Stock, the Company issues a proportionate number of Alclear Units in conjunction with the terms of the Reorganization. During the three months ended March 31, 2022, certain non-controlling interest holders exchanged their Alclear Units and corresponding shares of Class C Common Stock or Class D Common Stock for shares of the Company’s Class A Common Stock or Class B Common Stock, as applicable. As a result, the Company issued 1,025,318 shares of Class A Common Stock and 4,506 shares of Class B Common Stock. The 4,506 shares of Class B Common Stock were ultimately converted to shares of Class A Common Stock in connection with their sale, as required by the terms of the Company’s Second Amended and Restated Certificate of Incorporation.

Share-based Payment Arrangement [Abstract]
Incentive Plans	Incentive Plans 2021 Omnibus Incentive Plan The Clear Secure, Inc 2021 Omnibus Incentive Plan (“2021 Omnibus Incentive Plan”) became effective on June 29, 2021 to provide grants of equity-based awards to the employees, consultants, and directors of the Company and its affiliates. The 2021 Omnibus Incentive Plan authorized the issuance of up to 20,000,000 shares of Class A Common Stock as of the date of the Reorganization. The 2021 Omnibus Incentive Plan authorized the issuance of shares pursuant to the grant, settlement or exercise of restricted stock units (“RSUs”), restricted stock (“RSAs”), stock options and other share-based awards. Beginning with the first business day of each calendar year beginning in 2022 through 2031, the number of shares available will increase in an amount up to 5% of the total number of common shares outstanding (assuming exchange and/or conversion of all classes of common shares into Class A Common Stock) as of the last day of the immediately preceding year or a lesser amount approved by our board of directors or its compensation committee, so long as the total share reserve available for future awards at the time is not more than 12% of common shares outstanding (assuming exchange and/or conversion of all classes of common shares into Class A common stock). As a result of this provision, in March 2022, the Company filed a Registration Statement on Form S-8 registering the issuance of an additional 5,693,082 shares of Class A Common Stock that are reserved for issuance in respect of awards that may be granted under the 2021 Omnibus Incentive Plan. Alclear Holdings, LLC Equity Incentive Plan Prior to the Reorganization, Alclear granted profit unit awards and RSUs to various employees of the Company. In connection with the Company’s Reorganization described in Note 1, these awards were substituted as follows: • The Company substituted Alclear’s RSUs with RSUs under the 2021 Omnibus Incentive Plan. • The Company substituted Alclear’s performance vesting profit units with performance vesting RSUs under the 2021 Omnibus Incentive Plan. • The Company substituted Alclear’s other profit units with only a service vesting condition to RSAs under the 2021 Omnibus Incentive Plan. In all cases of the respective substitutions, the new awards retained the same terms and conditions (including applicable vesting requirements). Each award was converted to reflect the $31.00 share price contemplated in the Company’s IPO while retaining the same fair value. The RSUs originally granted by Alclear were subject to both service and liquidity event vesting conditions. The Company concluded that the Reorganization represented a qualifying liquidity event that would cause the RSUs’ liquidity event vesting conditions to be met. The following table summarizes information about the unvested profit units and RSUs in Alclear that were reclassified to RSAs or RSUs in the Company upon the Reorganization: Alclear RSU’s Weighted- Profit Units Weighted- Unvested balance, January 1, 2021 453,350 $ 14.51 9,085,704 $ 1.12 Granted 860,357 15.33 — 0.64 Vested — — (345,703) (0.40) Forfeited (25,479) (15.36) (881,227) (0.90) Effect of reorganization (1,288,228) (15.04) (7,858,774) (1.17) Unvested balance upon IPO — — — — Restricted Stock Awards In accordance with the Reorganization, the Company substituted Alclear Holdings’ profit units with service vesting conditions with RSAs, which are subject to the same vesting terms as applied to Alclear’s profit units; each also maintained the same fair value immediately before and after the exchange of the award. As such, there was no additional compensation expense that was recorded as a result of the substitution of the awards. The RSAs are subject to service-based vesting conditions and will vest on a specified date, provided the applicable service, generally three years, has been satisfied. The Company determines the fair value of each RSA based on the grant date and records the expense over the vesting period or requisite service period. The following is a summary of activity related to the RSAs associated with compensation arrangements during the three months ended March 31, 2022. RSA - Class A Common Stock Weighted- RSA - Alclear Units Weighted- Unvested balance as of January 1, 2022 1,429,883 $ 1.04 190,558 $ 1.29 Granted — — — — Vested (213,720) (1.29) — — Forfeited (60,349) (0.87) — — Unvested balance as of March 31, 2022 1,155,814 $ 1.00 190,558 $ 1.29 Below is the compensation expense (credit) related to the RSAs: Three Months Ended March 31, 2022 March 31, 2021 Cost of direct salaries and benefits $ 2 $ — General and administrative 63 301 Research and development 44 47 Sales and marketing 1 (21) Total $ 110 $ 327 As of March 31, 2022, estimated unrecognized expense for RSAs that are probable of vesting was $297 with such expense to be recognized over a weighted-average period of approximately 0.4 years subsequent to March 31, 2022. Restricted Stock Units The RSUs granted under the 2021 Omnibus Incentive Plan in substitution of Alclear awards were subject to the same vesting terms as applied to the Alclear awards and maintained the same fair value immediately before and after the exchange of the award. The RSUs are subject to both service-based and, in some cases, business performance-based vesting conditions. RSUs will vest on a specified date, provided the applicable service (generally three years) and, if applicable, business performance condition, have been satisfied. The RSUs with performance conditions issued are also subject to long-term revenue and cash-basis earnings performance hurdles (the “Financial Targets”). The Company determines the fair value of each RSU based on the grant date and records the expense over the vesting period or requisite service period. The following is a summary of activity related to the RSUs associated with compensation arrangements during the three months ended March 31, 2022: RSU’s Weighted- Unvested balance as of January 1, 2022 3,418,125 $ 23.56 Granted 1,312,449 24.66 Vested — — Forfeited (293,410) (12.52) Unvested balance as of March 31, 2022 4,437,164 $ 24.62 Below is the compensation expense recognized related to the RSUs: Three Months Ended March 31, 2022 March 31, 2021 Cost of direct salaries and benefits $ 91 $ — General and administrative 2,628 — Research and development 3,697 — Sales and marketing 48 — Total $ 6,464 $ — As of March 31, 2022, estimated unrecognized expense for RSUs that are probable of vesting was $68,703 with such expense to be recognized over a weighted-average period of approximately 1.2 years. Founder PSUs During June 2021, the Company established a long-term incentive compensation plan for the co-founders, which consists of performance restricted stock-unit awards (the “Founder PSUs”), that will be settled in shares of Class A Common Stock pursuant to the 2021 Omnibus Incentive Plan, subject to the satisfaction of both service and market based vesting conditions. The grant date fair value for the Founder PSUs was determined by a Monte Carlo simulation and discounted by the risk-free rate on the grant date and an expected volatility of 45%. The Founder PSUs are estimated to vest over a five year period, based on the achievement of specified price hurdles of the Company’s Class A Common Stock. The specified price hurdles of the Company’s Class A Common Stock will be measured on the volume-weighted average price per share for the trailing days during any 180 day period that ends within the applicable measurement period. In June 2021, the Company granted 4,208,617 Founder PSUs at a weighted average grant date fair value of $16.54. The Company recorded the expense related to these awards within general and administrative in the condensed consolidated statements of operations. As of March 31, 2022, estimated unrecognized expense for Founder PSUs was $49,731 with such expense to be recognized over a weighted-average period of approximately 1.10 years. Below is a summary of total compensation expense recorded in relation to the Company’s incentive plans, excluding additional expense related to repurchases: Three Months Ended March 31, 2022 March 31, 2021 RSAs $ 110 $ 327 RSUs 6,464 — Founder PSUs 6,485 — Total $ 13,059 $ 327 Three Months Ended March 31, 2022 March 31, 2021 Cost of direct salaries and benefits $ 94 $ — General and administrative 9,176 301 Research and development 3,741 47 Sales and marketing 48 (21) Total $ 13,059 $ 327

Earnings Per Share [Abstract]
Earnings (Loss) per Share	Earnings (Loss) per Share As described in Note 1, on June 29, 2021, the Operating Agreement was amended and restated to, among other things, (i) provide for a new single class of common membership interests, the Alclear Units, and (ii) exchange all of the then-existing membership interests of the original Alclear equity owners for Alclear Units. Basic and diluted earnings per share of Class A Common Stock and Class B Common Stock is applicable only for periods after June 29, 2021, post the Reorganization, when the Company had outstanding shares of Class A Common Stock and Class B Common Stock. Shares of the Company’s Class C Common Stock and Class D Common Stock do not participate in the earnings or losses of the Company and are therefore not participating securities. As such, separate presentation of basic and diluted earnings (loss) per share of Class C Common Stock and Class D Common Stock under the two-class method has not been presented. Each share of Class C Common Stock (together with a corresponding Alclear Unit) is exchangeable for one share of Class A Common Stock and each share of Class D Common Stock (together with a corresponding Alclear Unit) is exchangeable for one share of Class B Common Stock. Shares classified as treasury stock within the condensed consolidated balance sheets are excluded from the calculation of earnings (loss) per share. Additionally, the Company assumes the exercise for certain vested warrants exercisable for little to no consideration in the calculation of basic earnings per share. Below is the calculation of basic and diluted net loss per share: Three Months Ended March 31, 2022 Class A Class B Basic: Net loss attributable to Clear Secure, Inc. $ (10,189) $ (138) Weighted-average number of shares outstanding, basic 76,672,530 1,042,234 Net loss per common share, basic: $ (0.13) $ (0.13) Diluted: Net loss attributable to Clear Secure, Inc. $ (10,189) $ (138) Weighted-average number of shares outstanding, basic 76,672,530 1,042,234 Effect of dilutive shares — — Weighted-average number of shares outstanding, diluted 76,672,530 1,042,234 Net loss per common share, diluted: $ (0.13) $ (0.13) Due to the net loss for the periods presented, the following potential shares of common stock were determined to be anti-dilutive and were therefore excluded from the weighted-average share count in the computation of net loss per common share. Three Months Ended March 31, 2022 Class A Class B Exchangeable Alclear Units 43,580,905 26,705,315 Dilutive RSA’s 1,346,372 — Dilutive RSU’s 2,915,337 — Total 47,842,614 26,705,315 The Company has excluded certain potentially dilutive shares from the table above as they had performance conditions that were not achieved as of the end of the reporting period.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes As a result of the IPO and Reorganization, the Company became the sole managing member of Alclear, which is treated as a partnership for U.S. federal and most applicable state and local income tax purposes. As a partnership, Alclear is generally not subject to U.S. federal and most state and local income taxes. Any taxable income or loss generated by Alclear is passed through to and included in the taxable income or loss of its members, including us, on a pro rata basis. The Company is subject to U.S. federal income taxes, in addition to state and local income taxes with respect to our allocable share of any taxable income or loss of Alclear, as well as any stand-alone income or loss generated by the Company. The Company is also subject to income taxes in Israel, Argentina, and Mexico. The Company reported a tax provision of $302 on a pretax loss of $(18,492) for the three months ended March 31, 2022 as compared to $6 on pretax loss of $(13,122) for the three months ended March 31, 2021. This resulted in an effective tax rate of (1.63)% for the three months ended March 31, 2022 as compared to (0.04)% percent for the three months ended March 31, 2021. The Company's effective tax rate differs from the statutory rate primarily due to the following: (1) the impact of Alclear being a partnership and it allocating its taxable results to its non-controlling members, (2) movement in valuation allowance and (3) the impact of state and foreign taxes. The Company did not have significant unrecognized tax benefits and interest and penalties as of March 31, 2022. The Company is subject to income taxes in the U.S., Israel, Argentina, and Mexico. The statute of limitations for adjustments to our historic tax obligations will vary from jurisdiction to jurisdiction. The tax years for U.S. federal and state income tax purposes open for examination are for the years ending December 31, 2018 and forward. The tax years for foreign jurisdictions open for examination are for the years ending December 31, 2016 and forward. Tax Receivable Agreement As stated in Note 1, in connection with the IPO, the Company entered into the TRA, which generally provides for payment by the Company to the TRA Holders of 85% of the net cash savings, if any, in U.S. federal, state and local income tax and franchise tax that Clear Secure, Inc. actually realizes or is deemed to realize as a result of (i) any increase in tax basis in Alclear’s assets resulting from (a) exchanges by Alclear members (or their transferees or other assignees) of Alclear Units (along with the corresponding shares of our Class C Common Stock or Class D common stock, as applicable) for shares of the Company’s Class A Common Stock or Class B Common Stock, as applicable, and purchases of Alclear Units and corresponding shares of Class C Common Stock or Class D Common Stock, as the case may be, from the Alclear members (or their transferees or other assignees) or (b) payments under the TRA, and (ii) tax benefits related to imputed interest deemed arising as a result of payments made under the TRA. The Company will retain the benefit of the remaining 15% of these net cash savings. The TRA liability is calculated by determining the tax basis subject to TRA (“tax basis”) and applying a blended tax rate to the basis differences and calculating the iterative impact. The blended tax rate consists of the U.S. federal income tax rate and an assumed combined state and local income tax rate driven by the apportionment factors applicable to each state. Subsequent changes to the measurement of the TRA liability are recognized in the statements of operations as a component of other income (expense), net. The Company expects to obtain an increase in the share of the tax basis of its share of the assets of Alclear when Alclear Units are redeemed or exchanged by Alclear Members and other qualifying transactions. This increase in tax basis may have the effect of reducing the amounts that the Company would otherwise pay in the future to various tax authorities. The increase in tax basis may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets. During the three months ended March 31, 2022, the Company acquired 1,025,318 Alclear Units from certain stock holders. These exchanges resulted in a tax basis increase subject to the provisions of the TRA. The Company has not recognized the deferred tax asset for the step-up in tax basis, as the asset is not more-likely-than-not to be realized. Additionally, the Company has not recognized the TRA liability, as it is not probable that the TRA payments would be paid based on the Company’s historical loss position and would not be payable until the Company realizes tax benefit.

Under the repurchase program, the Company may purchase shares of its Class A Common Stock on a discretionary basis from time to time through open market repurchases, privately negotiated transactions, or other means, including through Rule 10b5-1 trading plans. The timing and actual number of shares repurchased will be determined by management depending on a variety of factors, including stock price, trading volume, market conditions, and other general business considerations. The repurchase program has no expiration date and may be modified, suspended, or terminated at any time.

Accounting Policies [Abstract]
Description and Organization	Description and Organization Clear Secure, Inc. (the “Company” and together with its consolidated subsidiaries, “CLEAR,” “we,” “us,” “our”) is a holding company and its principal asset is the controlling equity interest in Alclear Holdings, LLC (“Alclear”). Alclear was formed as a Delaware limited liability company on January 21, 2010 and operates under the terms of the Amended and Restated Operating Agreement dated June 29, 2021 (the “Operating Agreement”). As the sole managing member of Alclear, the Company operates and controls all of the business and affairs of Alclear, and through Alclear and its subsidiaries, conducts the Company’s business. The Company operates a secure identity platform under the brand name CLEAR primarily in the United States. CLEAR's current offerings include: CLEAR Plus, a consumer aviation subscription service, which enables access to predictable and fast experiences through dedicated entry lanes in airport security checkpoints nationwide; the flagship CLEAR App including Home to Gate and Health Pass; and Reserve powered by CLEAR, our virtual queuing technology that enables customers to manage lines.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements Emerging Growth Company Status The Company is an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies, until the earlier of the date that it (i) is no longer an EGC or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. Leases As of January 1, 2022, the Company adopted ASU No. 2016-02, Leases (Topic 842) (ASU 2016-02) on a modified retrospective basis with respect to all lease arrangements that existed as of the adoption date. Refer to Note 8 for further details. Current Expected Credit Losses As of January 1, 2022, the Company adopted, ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). There was no significant impact within the condensed consolidated financial statements as a result of adoption. Business Combinations In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers (“ASU 2021-08”). ASU 2021-08 addresses inconsistency related to the recognition and measurement of contract assets and contract liabilities acquired in a business combination. ASU 2021-08 requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination as if it had originated the contracts, in accordance with Topic 606, Revenue from Contracts with Customers. The guidance is effective for fiscal years beginning after December 15, 2022 and interim periods within those fiscal years. Early adoption of the amendments is permitted and an entity that early adopts should apply the amendments (1) retrospectively to all business combinations for which the acquisition date occurs on or after the beginning of the fiscal year that includes the interim period of early application and (2) prospectively to all business combinations that occur on or after the date of initial application. The Company continues to evaluate the impact of this standard on its consolidated financial statements. Other Recent Accounting Pronouncements Adopted and New Standards and Interpretations Not Yet Effective Other than the items discussed above, there are no standards issued by the FASB and adopted by the Company effective as of January 1, 2022 that had a material impact on the Company’s condensed consolidated financial statements. Additionally, there are no standards that are not yet effective that are expected to have a material impact on the Company’s condensed consolidated financial statements.
Basis of Accounting	The condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”) regarding interim financial reporting. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for complete financial statements and should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K (the “Form 10-K).Items included in the financial statements of each of the Company’s consolidated entities are measured using the currency of the primary economic environment in which the entity operates. The condensed consolidated financial statements are presented in US Dollars, which is the Company’s reporting currency.
Use of Estimates	Preparing financial statements requires management to make estimates and assumptions that affect the amounts that are reported in the financial statements and the accompanying disclosures, including the vesting of share-based and other deferred compensation plan awards. Although these estimates are based on management’s knowledge of current events and actions that the Company may undertake in the future, actual results may differ materially from the estimates.
Segment Reporting	The Company has one operating and reportable segment, which includes the operations of the businesses acquired during the year ended December 31, 2021.
Foreign Currency Transactions	Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at period-end exchange rates are recognized in other income (expense), net within the condensed consolidated statement of operations. The results and financial position of all the Company entities that have a functional currency different from the Company's reporting currency are translated into US Dollars as follows: •Assets and liabilities are translated at the closing rate at the reporting date; •Income and expenses for each statement of operation are translated at average exchange rates; and •All resulting exchange differences are recognized in other comprehensive loss.
Fair Value Measurements	Fair Value Measurements The Company values its available-for-sale securities and certain liabilities based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability in fair value measurements, a fair value hierarchy that prioritizes observable and unobservable inputs is used to measure fair value into three broad levels, which are described below: Level 1 – Quoted prices (unadjusted) in active markets that are accessible at the measurement date for identical assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs. Level 2 – Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in inactive markets or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated with observable market data. Level 3 – Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs to the extent possible. In addition, the Company considers counterparty credit risk in its assessment of fair value. The asset or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. The following is a description of the valuation methodologies used for assets and liabilities measured at fair value. Corporate bonds – Valued at the closing price reported on the active market on which the individual securities, all of which have counterparts with high credit ratings, are traded. Commercial paper – Value is based on yields currently available on comparable securities of issuers with similar credit ratings. Money market funds – Valued at the net asset value (“NAV”) of units of a collective fund. The NAV is used as a practical expedient to estimate fair value. This practical expedient is not used when it is determined to be probable that the fund will sell the investment for an amount different than the reported NAV. Contingent consideration – Valued at fair value using a simulation of targeted outcomes. Warrant liabilities – The Company had certain outstanding warrant liabilities prior to the Reorganization. These were valued based on significant inputs not observed in the market and, thus, represented a Level 3 measurement. The Company estimated the fair value of the liability using the Black-Scholes option pricing model and the change in fair value was recognized in general and administrative expenses. Refer to Note 13 for further information.
