Organization and Business; Business Combination Disclosure [Abstract]
Organization and Business; Business Combination	1. Organization and Business; Business Combination Principal Business NextNav Inc. and its consolidated subsidiaries, (collectively “NextNav” or the “Company”) delivers next generation positioning, navigation and timing (“PNT”) solutions through network-based solutions, including the Pinnacle system. The Pinnacle system provides “floor-level” altitude service to any device with a barometric pressure sensor, including most off-the-shelf Android and iOS smartphones. The TerraPoiNT system is a terrestrial-based, encrypted network designed to overcome the limitations inherent in the space-based nature of global positioning system (“GPS”) through a network of specialized wide area location transmitters that broadcasts an encrypted PNT signal on a licensed 900 MHz spectrum. NextNav has devoted substantially all of its efforts to date to planning and organization, the development of its network, ongoing research and development programs, and securing adequate capital for anticipated operations. Since its inception, NextNav has incurred recurring losses and generated negative cash flows from operations and has primarily relied upon debt and equity financings to fund its cash requirements. Business Combination On October 28, 2021, the Company consummated the previously announced business combination pursuant to the terms of the Agreement and Plan of Merger (the “Merger Agreement”), dated as of June 9, 2021, by and among the Company, Spartacus Acquisition Corporation, a Delaware corporation (“Spartacus”), NextNav Holdings, LLC, a Delaware limited liability company (“Holdings”) and the other parties thereto (the “Business Combination”). As a result of the Business Combination, the Company changed its name from Spartacus Acquisition Shelf Corp. to NextNav Inc., and certain blocker entities formed by Holdings equity holders, Holdings and the various operating subsidiaries of Holdings became the Company’s wholly owned subsidiaries, with the equity holders of each of such blocker entities and Holdings and Spartacus’ stockholders becoming stockholders in NextNav. While the legal acquirer in the Business Combination is Spartacus, for financial accounting and reporting purposes under accounting principles generally accepted in the United States (“U.S. GAAP”), Holdings is deemed to be the accounting acquirer, with the Business Combination being accounted for as a “reverse recapitalization.” A reverse recapitalization does not result in a new basis of accounting. Accordingly, the reverse recapitalization was treated as the equivalent of Holdings issuing stock for the net assets of Spartacus, accompanied by a recapitalization. The net assets of Spartacus are stated at historical costs, with no goodwill or other intangible assets recorded.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in these condensed consolidated financial statements. The consolidated assets, liabilities and results of operations prior to the reverse recapitalization are those of Holdings. The outstanding shares and corresponding capital amounts, and losses per share, prior to the reverse recapitalization, have been retroactively restated in accordance with Accounting Standards Codification 805, Business Combinations. Unaudited Interim Financial Information The condensed consolidated financial statements as of March 31, 2022 are unaudited. These interim financial statements of NextNav have been prepared in accordance with U.S. GAAP and Securities and Exchange Commission (“SEC”) instructions for interim financial information and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Form 10-K”), which we filed with the SEC on March 23, 2022. The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and reflect, in management’s opinion, all adjustments of a normal, recurring nature that are necessary for the fair statement of the Company’s balance sheets, results of operations, and cash flows for the three-month periods, but are not necessarily indicative of the results expected for the full fiscal year or any other period. There have been no changes to the Company’s significant accounting policies described in the 2021 Form 10-K that have had a material impact on these condensed consolidated financial statements and related notes. The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period and accompanying notes. These estimates include those related to the useful lives and recoverability of long-lived and intangible assets, valuation of common stock warrants, income taxes and equity-based compensation, among others. NextNav bases estimates on historical experience, anticipated results and various other assumptions, including assumptions of future events, it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets, liabilities, equity, revenue and expenses, that are not readily apparent from other sources. Actual results and outcomes could differ materially from these estimates and assumptions. Revenue The following table presents the Company’s revenue disaggregated by category and source: Three Months Ended 2022 2021 (in thousands) Commercial $ 1,180 $ - Government contracts 10 251 Equipment sales 9 - Total revenue $ 1,199 $ 251 Contract Balances Accounts receivable are billed and unbilled amounts related to the Company’s rights to consideration as performance obligations are satisfied when the rights to payment become unconditional but for the passage of time. As of March 31, 2022 and December 31, 2021, the Company’s accounts receivable balances were comprised of $0.04 million and $1.7 million, respectively. Contract liabilities relate to amounts billed in advance, or advance consideration received from customers, for which transfer of control of the good or service occurs at a later point in time. As of March 31, 2022 and December 31, 2021, the Company’s contract liabilities were $0.5 million and $1.6 million, respectively. Equity-Based Compensation Measurement of equity-based compensation with employees is based on the estimated grant date fair value of the equity instruments issued. The fair value of stock options is determined using the Black-Scholes option pricing model. The fair value of restricted stock awards is based on the closing price of NextNav’s common stock on the date of grant. NextNav recognizes equity-based compensation on a straight-line basis over the requisite service period of the grant, which is generally equal to the vesting period. NextNav accounts for forfeitures as they occur. The following details the amount of stock-based compensation included in cost of goods sold, research and development, and selling, general and administrative expenses: Three Months Ended 2022 2021 (in thousands) Cost of goods sold $ 644 $ 21 Research and development 1,794 145 Selling, general and administrative 4,757 219 Total stock-based compensation expense $ 7,195 $ 385 Basic and Diluted Net Loss per Share Basic loss per share (“EPS”) excludes dilution for common share equivalents and is computed by dividing net loss available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS is based on the weighted-average number of shares of common stock outstanding during each period, adjusted for the effect of dilutive common share equivalents. Restricted shares are included in the computation of basic EPS as they vest and are included in diluted EPS, to the extent they are dilutive, determined using the treasury stock method. Outstanding options are included in the computation of diluted EPS, to the extent they are dilutive, determined using the treasury stock method. In connection with the closing of the Business Combination, AT&T Services, Inc. and certain of its affiliates (“AT&T”) elected to exchange its outstanding warrants in Holdings for a new warrant to purchase an aggregate of 4,320,133 shares of NextNav’s common stock at an exercise price of $0.01 (the “AT&T Warrant”). The AT&T Warrant is expected to be net settled upon redemption, resulting in an issuance of 4,315,813 of NextNav’s common stock. The exercise price represents little consideration compared to the Company’s common stock and there are no other vesting conditions or contingencies associated with them. Accordingly, they are included in the basic EPS calculation during the applicable period. The Company has not considered the effect of the warrants to purchase an aggregate of 18,749,990 shares in the calculation of diluted loss per share, since the exercise of the warrants are contingent upon the occurrence of future events and the inclusion of such warrants would be anti-dilutive. The determination of the diluted weighted average shares is included in the following calculation of EPS: Three Months Ended 2022 2021 (in thousands, except per share amounts) Numerator Net loss $ 9,711 $ 27,068 Less: cumulative change in redemption value of preferred units — 8,188 Net loss attributable to common stockholders $ 9,711 $ 35,256 Denominator Weighted average shares – basic and diluted 100,868 7,346 Basic and diluted loss per share $ 0.10 $ 4.80 The following details anti-dilutive unvested restricted stock units, as well as the anti-dilutive effects of the outstanding warrants, stock options and preferred units: March 31, Antidilutive Shares Excluded 2022 2021 (in thousands) Warrants 18,750 17,667 Stock Options 2,500 2,047 Unvested Restricted Stock Units 3,399 145 Unvested Restricted Stock Awards 1,070 — Preferred units — 47,652 Leases NextNav leases office space under a non-cancellable lease as well as site leases for towers and shelters under operating leases related to its network under construction. Site leases are entered into throughout the United States under which NextNav receives the rights to install equipment used to transmit its services over its licensed spectrum. The Company, at the inception of the contract, determines whether a contract is or contains a lease based on assessment of the terms and conditions of the contract. The Company classifies leases with contractual terms longer than twelve months as either operating or finance. The Company has elected not to recognize lease assets and liabilities for its short-term leases, which are defined as leases with an initial term of twelve months or less. The Company’s leases may include options to extend or terminate the lease. The option to renew may be automatic, at the option of NextNav or mutually agreed to between the landlord and NextNav. Lease terms include the non-cancellable term and periods under options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company’s lease agreements generally contain lease and non-lease components. Payments under the lease arrangements are primarily fixed. Non-lease components primarily include payments for utilities and maintenance. The Company combines fixed payments for non-lease components with lease payments and account for them together as a single lease component which increases the amount of the Company’s lease assets and liabilities. Certain lease agreements contain variable payments, which are expensed as incurred and not included in the lease assets and liabilities. These amounts include payments for common area maintenance. Lease assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is the Company’s incremental borrowing rate, because the interest rate implicit in the Company’s leases is not readily determinable. The Company’s incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. Lease assets are reduced by landlord incentives, plus any direct costs from executing the leases or lease prepayments reclassified from “Other current assets” upon lease commencement. Operating lease assets and liabilities are included on the Condensed Consolidated Balance Sheet beginning January 1, 2022. Operating lease expense is recognized on a straight-line basis over the lease term. Monthly rent expense includes any site related utility payments or other fees such as administrative or up-front fees contained in the lease agreements that are determinable upon execution of the lease agreement. Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) (“ASU 2016-02”), which requires lessees to recognize lease assets and lease liabilities on the Consolidated Balance Sheet for those leases classified as operating leases under current U.S. GAAP. ASU 2016-02 requires that a lessee should recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term on the Consolidated Balance Sheet. The new guidance also requires qualitative and quantitative disclosures related to the nature, timing and uncertainty of cash flows arising from leases. In July 2018, the FASB amended the new lease standard which, among other changes, allows a company to elect to adopt ASU 2016-02 using a transition option whereby a cumulative effect adjustment is recorded to the opening balance of its retained earnings on the adoption date. The Company has elected to use this modified retrospective transition option and recorded a cumulative effect adjustment to retained earnings of $0.5 million, net of tax, as of January 1, 2022. The Company also elected certain practical expedients permitted under the transition guidance, including to retain the historical lease classification as well as relief from reviewing expired or existing contracts to determine if they contain leases. The adoption of ASU 2016-02 resulted in the recognition of operating lease right-of-use assets and liabilities of $13.4 million and $10.5 million, respectively. The standard did not have a significant effect on the Condensed Consolidated Statements of Comprehensive Loss and Cash Flows. See Note 4 for additional lease disclosures. In December 2019, FASB issued ASU 2019-02, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”), which is intended to improve consistency and simplify several areas of existing guidance. ASU 2019-12 removes certain exceptions to the general principles related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 is effective for the Company’s fiscal year beginning January 1, 2022. The Company adopted this ASU as of January 1, 2022. The adoption did not have a material impact on the consolidated financial statements. Recent Accounting Developments Not Yet Adopted In June 2016, FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) (“ASU 2016-13”), which requires that an entity measure and recognize expected credit losses for financial assets held at amortized cost and replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that requires consideration of a broader range of information to estimate credit losses. The guidance also modifies the impairment model for available-for-sale debt securities. ASU 2016-13 is effective for the Company’s fiscal year beginning January 1, 2023. The Company is continuing to assess the potential impacts of ASU 2016-13 on its financial statements.

Warrants and Warrant Liability Disclosure [Abstract]
Warrants and Warrant Liability	5. Warrants and Warrant Liability As of March 31, 2022, NextNav had 18,749,990 warrants outstanding including: (a) 9,999,990 public warrants sold in connection with Spartacus’ initial public offering (the “Public Warrants”) and (b) 8,750,000 warrants issued in a private placement on the initial public offering closing date (the “Private Placement Warrants”). Holders of the Public Warrants and Private Placement Warrants are entitled to acquire shares of common stock of NextNav. Each whole warrant entitles the registered holder to purchase one share at an exercise price of $11.50 per share. The Public Warrants and Private Placement Warrants expire five years after the completion of the Business Combination. NextNav has the right to redeem the outstanding Public Warrants in whole and not in part at a price of $0.01 per warrant upon a minimum of 30 days’ prior written notice of redemption, if and only if the last sales price of the Company’s common stock matched or exceeded $18.00 per share for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which NextNav sends the notice of redemption to the warrant holders. The Private Placement Warrants are identical in all respects to the Public Warrants except that, so long as they are held by the current holder or its permitted transferees: (i) they will not be redeemable by NextNav; (ii) they may be exercised by the holders on a cashless basis; and (iii) they are subject to registration rights.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	6. Fair Value NextNav uses observable and unobservable inputs to determine the value of its assets and liabilities recorded at fair value. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. The three-tier hierarchy for inputs used to measure fair value, which prioritizes the inputs used in the methodologies of measuring fair value for assets and liabilities, where applicable, is as follows: - Level 1 — Quoted prices in active markets for identical assets or liabilities - Level 2 — Observable inputs other than quoted prices in active markets for identical assets and liabilities - Level 3 — No observable pricing inputs in the market Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurements. NextNav’s assessment of the significance of a particular input to the fair value measurements requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy. NextNav effectuates transfers between levels of the fair value hierarchy, if any, as of the date of the actual circumstance that caused the transfer. The following table presents the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis: Level 1 Level 2 Level 3 Total (in thousands) March 31, 2022 Warrants — — $ 22,488 $ 22,488 December 31, 2021 Warrants — — $ 28,875 $ 28,875 The carrying values of cash and cash equivalents, accounts payable, accrued expenses and other current liabilities, amounts included in other current assets, and current liabilities that meet the definition of a financial instrument, approximate fair value due to their short-term nature. Assets, liabilities, and equity instruments that are measured at fair value on a nonrecurring basis include fixed assets and intangible assets. The Company recognizes these items at fair value when they are considered to be impaired or upon initial recognition. The fair value of these assets and liabilities are determined with valuation techniques using the best information available and may include quoted market prices, market comparables and discounted cash flow models. Level 3 Liabilities The Company engaged a third-party valuation firm to assist with the fair value analysis of the warrants. The analysis used commonly accepted valuation methodologies and best practices to determine the fair value of the equity, in accordance with fair value standards and U.S. GAAP. For the Private Placement Warrants that were outstanding as of March 31, 2022 and December 31, 2021, NextNav used a Monte Carlo simulation model. The following table shows the assumptions used in each respective model: March 31, December 31, Values Values Stock Price $ 7.49 $ 8.76 Strike price $ 11.50 $ 11.50 Holding Period/Term (years) 4.58 4.80 Volatility 53.4 % 52.90 % Expected dividends None None Risk-Free Rate 2.43 % 1.23 % Fair value of warrants $ 2.57 $ 3.30 The table below provides a reconciliation of the beginning and ending balances for the liabilities measured at fair value using significant unobservable inputs (Level 3).

Income Tax Disclosure [Abstract]
Income Taxes	9. Income Taxes The Company computes its year-to-date provision for income taxes by applying the estimated annual effective tax rate to year-to-date pretax income or loss and adjusts the provision for discrete tax items recorded in the period. A valuation allowance has been established against the Company’s U.S. federal and state deferred tax assets, which results in an annualized effective tax rate for the Company’s U.S. operations of 0%. For the three months ended March 31, 2022, the Company recorded an income tax provision of $0.03 million on a pretax loss of $9.6 million related to foreign tax activity, resulting in an effective tax rate of (0.3)%. For the three months ended March 31, 2021, the Company recorded an income tax provision of $0.02 million on a pretax loss of $27.1 million related to foreign tax activity, resulting in an effective tax rate of (0.07)%. These effective tax rates differ from the U.S. federal statutory rate primarily due to the valuation allowance against the Company’s domestic deferred tax assets.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in these condensed consolidated financial statements. The consolidated assets, liabilities and results of operations prior to the reverse recapitalization are those of Holdings. The outstanding shares and corresponding capital amounts, and losses per share, prior to the reverse recapitalization, have been retroactively restated in accordance with Accounting Standards Codification 805, Business Combinations.
Unaudited Interim Financial Information	Unaudited Interim Financial Information The condensed consolidated financial statements as of March 31, 2022 are unaudited. These interim financial statements of NextNav have been prepared in accordance with U.S. GAAP and Securities and Exchange Commission (“SEC”) instructions for interim financial information and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Form 10-K”), which we filed with the SEC on March 23, 2022. The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and reflect, in management’s opinion, all adjustments of a normal, recurring nature that are necessary for the fair statement of the Company’s balance sheets, results of operations, and cash flows for the three-month periods, but are not necessarily indicative of the results expected for the full fiscal year or any other period. There have been no changes to the Company’s significant accounting policies described in the 2021 Form 10-K that have had a material impact on these condensed consolidated financial statements and related notes.
Use of Estimates	The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period and accompanying notes. These estimates include those related to the useful lives and recoverability of long-lived and intangible assets, valuation of common stock warrants, income taxes and equity-based compensation, among others. NextNav bases estimates on historical experience, anticipated results and various other assumptions, including assumptions of future events, it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets, liabilities, equity, revenue and expenses, that are not readily apparent from other sources. Actual results and outcomes could differ materially from these estimates and assumptions.
Revenue	Revenue The following table presents the Company’s revenue disaggregated by category and source:
Contract Balances	Contract Balances Accounts receivable are billed and unbilled amounts related to the Company’s rights to consideration as performance obligations are satisfied when the rights to payment become unconditional but for the passage of time. As of March 31, 2022 and December 31, 2021, the Company’s accounts receivable balances were comprised of $0.04 million and $1.7 million, respectively. Contract liabilities relate to amounts billed in advance, or advance consideration received from customers, for which transfer of control of the good or service occurs at a later point in time. As of March 31, 2022 and December 31, 2021, the Company’s contract liabilities were $0.5 million and $1.6 million, respectively.
Equity-Based Compensation	Equity-Based Compensation Measurement of equity-based compensation with employees is based on the estimated grant date fair value of the equity instruments issued. The fair value of stock options is determined using the Black-Scholes option pricing model. The fair value of restricted stock awards is based on the closing price of NextNav’s common stock on the date of grant. NextNav recognizes equity-based compensation on a straight-line basis over the requisite service period of the grant, which is generally equal to the vesting period. NextNav accounts for forfeitures as they occur. The following details the amount of stock-based compensation included in cost of goods sold, research and development, and selling, general and administrative expenses:
Basic and Diluted Net Loss per Share	Basic and Diluted Net Loss per Share Basic loss per share (“EPS”) excludes dilution for common share equivalents and is computed by dividing net loss available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS is based on the weighted-average number of shares of common stock outstanding during each period, adjusted for the effect of dilutive common share equivalents. Restricted shares are included in the computation of basic EPS as they vest and are included in diluted EPS, to the extent they are dilutive, determined using the treasury stock method. Outstanding options are included in the computation of diluted EPS, to the extent they are dilutive, determined using the treasury stock method. In connection with the closing of the Business Combination, AT&T Services, Inc. and certain of its affiliates (“AT&T”) elected to exchange its outstanding warrants in Holdings for a new warrant to purchase an aggregate of 4,320,133 shares of NextNav’s common stock at an exercise price of $0.01 (the “AT&T Warrant”). The AT&T Warrant is expected to be net settled upon redemption, resulting in an issuance of 4,315,813 of NextNav’s common stock. The exercise price represents little consideration compared to the Company’s common stock and there are no other vesting conditions or contingencies associated with them. Accordingly, they are included in the basic EPS calculation during the applicable period. The Company has not considered the effect of the warrants to purchase an aggregate of 18,749,990 shares in the calculation of diluted loss per share, since the exercise of the warrants are contingent upon the occurrence of future events and the inclusion of such warrants would be anti-dilutive. The determination of the diluted weighted average shares is included in the following calculation of EPS: Three Months Ended 2022 2021 (in thousands, except per share amounts) Numerator Net loss $ 9,711 $ 27,068 Less: cumulative change in redemption value of preferred units — 8,188 Net loss attributable to common stockholders $ 9,711 $ 35,256 Denominator Weighted average shares – basic and diluted 100,868 7,346 Basic and diluted loss per share $ 0.10 $ 4.80 The following details anti-dilutive unvested restricted stock units, as well as the anti-dilutive effects of the outstanding warrants, stock options and preferred units:
Leases	Leases NextNav leases office space under a non-cancellable lease as well as site leases for towers and shelters under operating leases related to its network under construction. Site leases are entered into throughout the United States under which NextNav receives the rights to install equipment used to transmit its services over its licensed spectrum. The Company, at the inception of the contract, determines whether a contract is or contains a lease based on assessment of the terms and conditions of the contract. The Company classifies leases with contractual terms longer than twelve months as either operating or finance. The Company has elected not to recognize lease assets and liabilities for its short-term leases, which are defined as leases with an initial term of twelve months or less. The Company’s leases may include options to extend or terminate the lease. The option to renew may be automatic, at the option of NextNav or mutually agreed to between the landlord and NextNav. Lease terms include the non-cancellable term and periods under options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company’s lease agreements generally contain lease and non-lease components. Payments under the lease arrangements are primarily fixed. Non-lease components primarily include payments for utilities and maintenance. The Company combines fixed payments for non-lease components with lease payments and account for them together as a single lease component which increases the amount of the Company’s lease assets and liabilities. Certain lease agreements contain variable payments, which are expensed as incurred and not included in the lease assets and liabilities. These amounts include payments for common area maintenance. Lease assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is the Company’s incremental borrowing rate, because the interest rate implicit in the Company’s leases is not readily determinable. The Company’s incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. Lease assets are reduced by landlord incentives, plus any direct costs from executing the leases or lease prepayments reclassified from “Other current assets” upon lease commencement. Operating lease assets and liabilities are included on the Condensed Consolidated Balance Sheet beginning January 1, 2022. Operating lease expense is recognized on a straight-line basis over the lease term. Monthly rent expense includes any site related utility payments or other fees such as administrative or up-front fees contained in the lease agreements that are determinable upon execution of the lease agreement.
Adopted Accounting Pronouncements	Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) (“ASU 2016-02”), which requires lessees to recognize lease assets and lease liabilities on the Consolidated Balance Sheet for those leases classified as operating leases under current U.S. GAAP. ASU 2016-02 requires that a lessee should recognize a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term on the Consolidated Balance Sheet. The new guidance also requires qualitative and quantitative disclosures related to the nature, timing and uncertainty of cash flows arising from leases. In July 2018, the FASB amended the new lease standard which, among other changes, allows a company to elect to adopt ASU 2016-02 using a transition option whereby a cumulative effect adjustment is recorded to the opening balance of its retained earnings on the adoption date. The Company has elected to use this modified retrospective transition option and recorded a cumulative effect adjustment to retained earnings of $0.5 million, net of tax, as of January 1, 2022. The Company also elected certain practical expedients permitted under the transition guidance, including to retain the historical lease classification as well as relief from reviewing expired or existing contracts to determine if they contain leases. The adoption of ASU 2016-02 resulted in the recognition of operating lease right-of-use assets and liabilities of $13.4 million and $10.5 million, respectively. The standard did not have a significant effect on the Condensed Consolidated Statements of Comprehensive Loss and Cash Flows. See Note 4 for additional lease disclosures. In December 2019, FASB issued ASU 2019-02, Simplifying the Accounting for Income Taxes (Topic 740) (“ASU 2019-12”), which is intended to improve consistency and simplify several areas of existing guidance. ASU 2019-12 removes certain exceptions to the general principles related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 is effective for the Company’s fiscal year beginning January 1, 2022. The Company adopted this ASU as of January 1, 2022. The adoption did not have a material impact on the consolidated financial statements.
Recent Accounting Developments Not Yet Adopted	Recent Accounting Developments Not Yet Adopted In June 2016, FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) (“ASU 2016-13”), which requires that an entity measure and recognize expected credit losses for financial assets held at amortized cost and replaces the incurred loss impairment methodology in current U.S. GAAP with a methodology that requires consideration of a broader range of information to estimate credit losses. The guidance also modifies the impairment model for available-for-sale debt securities. ASU 2016-13 is effective for the Company’s fiscal year beginning January 1, 2023. The Company is continuing to assess the potential impacts of ASU 2016-13 on its financial statements.
