DESCRIPTION OF THE BUSINESS
DESCRIPTION OF THE BUSINESS	NOTE A — DESCRIPTION OF THE BUSINESS Organization Monocle Acquisition Corporation (“Monocle”) was initially formed on August 20, 2018 for the purpose of effecting a merger, share exchange, asset acquisition, stock purchase, recapitalization, reorganization or similar business combination with one or more businesses. ​ On December 22, 2020, (the “Closing Date”), Monocle consummated the previously announced business combination pursuant to that certain Amended and Restated Agreement and Plan of Merger, dated September 8, 2020 (the “Merger Agreement”) by and among Monocle, AerSale Corporation (f/k/a Monocle Holdings Inc.), a Delaware corporation (the “Company”), AerSale Aviation, Inc. (f/k/a AerSale Corp.), a Delaware corporation (“AerSale Aviation”), Monocle Merger Sub 1 Inc., a Delaware corporation (“Merger Sub 1”), Monocle Merger Sub 2 LLC, a Delaware limited liability company (“Merger Sub 2”), and Leonard Green & Partners, L.P., a Delaware limited partnership, solely in its capacity as the initial Holder Representative (as defined in the Merger Agreement). The transactions contemplated by the Merger Agreement are referred to herein as the “Merger” or the “Business Combination” and in connection therewith, Monocle merged with and into us, whereby the Company survived the merger and became the successor issuer to Monocle by operation of Rule 12g-3 under the Exchange Act. ​ Upon the consummation of the Merger: (a) Merger Sub 1 was merged with and into Monocle, with Monocle surviving the merger as a wholly-owned direct subsidiary of the Company (the “First Merger”), and (b) Merger Sub 2 was merged with and into AerSale Aviation, with AerSale Aviation surviving the merger as a wholly-owned indirect subsidiary of the Company (the “Second Merger”). In connection with the closing of the Business Combination (the “Closing”), AerSale Aviation changed its name from “AerSale Corp.” to “AerSale Aviation, Inc.” and the Company changed its name from “Monocle Holdings Inc.” to “AerSale Corporation.” Immediately following the Merger, the Company contributed all of its ownership in Monocle to AerSale Aviation which will continue as a wholly owned subsidiary of the Company. ​ The Company’s corporate headquarters are based in Miami, Florida, with additional offices, hangars, and warehouses globally.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE B — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Interim Financial Statements The accompanying unaudited interim consolidated financial statements have been prepared from the books and records of the Company in accordance with accounting principles Generally Accepted in the United States (“U.S. GAAP”) for interim financial information and Rule 10-01 of Regulation S-X promulgated by the U.S. Securities and Exchange Commission (“SEC”), which permits reduced disclosures for interim periods. Although these interim consolidated financial statements do not include all of the information and footnotes required for complete annual consolidated financial statements, management believes all adjustments, consisting only of normal recurring adjustments, and disclosures necessary for a fair presentation of the accompanying condensed consolidated balance sheets, statements of operations, stockholders’ equity, and cash flows have been made. Unaudited interim results of operations and cash flows are not necessarily indicative of the results that may be expected for the full year. Unaudited interim condensed consolidated financial statements and footnotes should be read in conjunction with the audited consolidated financial statements and footnotes included in Part II, Item 8 of the Annual Report Revenue Recognition Products — Used Serviceable Material Sales (“USM”) Revenues from sales of USM are measured based on consideration specified within customer contracts, and excludes any sales commissions and taxes collected and remitted to government agencies. The Company recognizes revenue when performance obligations are satisfied by transferring control of a product or service to a customer. The parts are sold at a fixed price with no right of return. In determining the performance obligation, management has identified the promise in the contract to be the shipment of the spare parts to the customer. Title passes to the buyer when the goods are shipped, the buyer is responsible for any loss in transit and the Company has a legal right to payment for the spare parts once shipped. The Company generally sells its USM products under standard 30-day payment terms, subject to certain exceptions. Customers neither have the right to return products nor do they have the right to extended financing. The Company has determined that physical acceptance of the spare parts to be a formality in accordance with Accounting Standards Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers” (“ASC 606”). Spare parts revenue is based on a set price for a set number of parts as defined in the purchase order. The performance obligation is completed once the parts have shipped and as a result, all of the transaction price is allocated to that performance obligation. The Company has determined that it is appropriate to recognize spare parts sales at a point in time (i.e., the date the parts are shipped) in accordance with ASC 606. Products — Whole Asset Sales Revenues from whole asset sales are measured based on consideration specified in the contract with the customer. The Company and customer enter into an agreement which outlines the place and date of sale, purchase price, condition of the whole asset, bill of sale and the assignment of rights and warranties from the Company to the customer. The Company believes the whole asset holds standalone value to the customer as it is not dependent on any other services for functionality purposes and therefore is distinct within the context of the contract and as described in ASC 606-10. Accordingly, the Company has identified the transfer of the whole asset as the performance obligation. The transaction price is set at a fixed dollar amount per fixed quantity (number of whole assets) and is explicitly stated in each contract. Whole asset sales revenue is based on a set price for a set number of assets, which is allocated to the performance obligation discussed above, in its entirety. The Company has determined the date of transfer to the customer is the date the customer obtains control over the asset and would cause the revenue recognition. Payment is required in full upon a customer’s acceptance of the whole asset on the date of the transfer. Leasing Revenues The Company leases flight equipment under operating leases that contain monthly base rent and reports rental income straight line over the life of the lease as it is earned. Additionally, the Company’s leases provide for supplemental rent, which is calculated based on actual hours or cycles of utilization and, for certain components, based on the amount of time until maintenance of that component is required. In certain leases, the Company records supplemental rent paid by the lessees as maintenance deposit payment liabilities in recognition of the Company’s contractual commitment to reimburse qualifying maintenance. Reimbursements to the lessees upon receipt of evidence of qualifying maintenance work are charged against the existing maintenance deposit payments liabilities. In leases where the Company is responsible for performing certain repairs or replacement of aircraft components or engines, supplemental rent is recorded as revenue in the period earned. In the event of premature lease termination or lessee default on the lease terms, revenue recognition will be discontinued when outstanding balances are beyond the customers’ deposits held. Payment terms for leased flight equipment are due upon receipt. Service Revenues Service revenues are recognized as performance obligations when they are fulfilled and the benefits are transferred to the customer. At contract inception, the Company evaluates if the contract should be accounted for as a single performance obligation or if the contract contains multiple performance obligations. In some cases, the Company’s service contract with the customer is considered one performance obligation as it includes factors such as the good or service being provided is significantly integrated with other promises in the contract, the service provided significantly modifies or customizes the other good or service or the goods or services are highly interdependent or interrelated with each other. If the contract has more than one performance obligation, the Company determines the standalone price of each distinct good or service underlying each performance obligation and allocates the transaction price based on their relative standalone selling prices. The transaction price of a contract, which can include both fixed and variable amounts, is allocated to each performance obligation identified. Some contracts contain variable consideration, which could include incremental fees or penalty provisions related to performance. Variable consideration that can be reasonably estimated based on current assumptions and historical information is included in the transaction price at the inception of the contract but limited to the amount that is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. Variable consideration that cannot be reasonably estimated is recorded when known. For most service contracts, performance obligations are satisfied over time as work progresses based on transfer of control of products and services to our customers. The Company receives payments from our customers based on billing schedules or contract terms. For performance obligations that are satisfied over time, the Company measures progress in a manner that depicts the performance of transferring control to the customer. As such, the Company utilizes the input method of cost-to-cost to recognize revenue over time as this depicts when control of the promised goods or services are transferred to the customer. Revenue is recognized based on the relationship of actual costs incurred to date to the estimated total cost at completion of the performance obligation. The Company is required to make certain judgments and estimates, including estimated revenues and costs, as well as inflation and the overall profitability of the arrangement. Key assumptions involved include future labor costs and efficiencies, overhead costs and ultimate timing of product delivery. Differences may occur between the judgments and estimates made by management and actual program results. Under most of the Company’s Maintenance, Repair and Overhaul (“MRO”) contracts, if the contract is terminated for convenience, the Company is entitled to payment for items delivered, fair compensation for work performed, the costs of settling and paying other claims and a reasonable profit on the costs incurred or committed. Changes in estimates and assumptions related to our arrangements accounted for using the input method based on labor hours are recorded using the cumulative catchup method of accounting. These changes are primarily adjustments to the estimated profitability for our long term programs where the Company provides MRO services. The Company has elected to use certain practical expedients permitted under ASC 606. Shipping and handling fees and costs incurred associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost, are included in cost of sales in our condensed consolidated statements of operations and are not considered a performance obligation to our customers. The Company’s reported sales on our condensed consolidated statements of operations are net of any sales or related non income taxes. The Company also utilizes the “as invoiced” practical expedient in certain cases where performance obligations are satisfied over time and the invoiced amount corresponds directly with the value the Company is providing to the customer. Revision of Prior Period Financial Statements During the nine months ended September 30, 2021, the Company identified and corrected immaterial errors that affected certain of its previously issued consolidated financial statements. These errors related to the misapplication of generally accepted accounting principles in the United States in connection with the classification of the Company’s private warrants as equity. The SEC released a Public Statement on April 12, 2021 noting that when one or more features common to warrants in SPAC transactions is included in a warrant, the warrant “should be classified as a liability measured at fair value, with changes in fair value each period reported in earnings.” Following review of the SEC’s statement, the Company concluded that its private warrants do not meet the conditions to be classified as equity and instead, the private warrants meet the definition of a derivative under ASC 815 “Derivatives and Hedging.” This requires the Company to record the private warrants as a liability measured at fair value on the Company’s Condensed Consolidated Balance Sheets with the changes in fair value each period reported in earnings. As a result, in the three and nine months ended September 30, 2021, the Company recorded $2.1 million and $2.7 million, respectively, reflected as change in fair value of warrant liability. Accordingly, the Company revised its December 31, 2020 financial statements by recognizing the private warrants as a liability upon the consummation of the Business Combination on December 22, 2020 in the amount of $1.2 million with a corresponding reduction to additional paid-in capital and retained earnings of $0.8 million and $0.4 million, respectively. ​ The Company determined the impact of the error related to the accounting treatment of private warrants had an immaterial impact with respect to the Company’s consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2020. However, in order to correctly present the immaterial errors noted above, previously issued comparative financial statements have been revised as of the quarter ended March 31, 2021. ​ New Accounting Pronouncements Not Yet Adopted In February 2016, the FASB issued ASU 2016-02 Leases (Topic 842), which generally requires companies to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet. In July 2018, FASB issued ASU No. 2018-10, “Codification Improvements to Topic 842, Leases” and ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements.” Although early adoption is permitted, the Company plans to adopt Topic 842 during the first quarter of 2022, on a modified retrospective basis. The Company is currently evaluating the impact this guidance will have on our consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016-13 (“ASU 2016-13”), “Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” In November 2018, FASB issued ASU No. 2018-19, “Codification Improvements to Topic 326, Financial Instruments — Credit Losses,” which amends the scope and transition requirements of ASU 2016-13. Topic 326 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount. Topic 326 will become effective for the Company beginning January 1, 2023, with early adoption permitted, on a modified retrospective basis. The Company is currently evaluating the impact this guidance will have on our consolidated financial statements and related disclosures. ​ Payroll Support Programs The Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law on March 27, 2020 and is intended to assist the economy by issuing a relief package to preserve jobs in industries adversely impacted by the COVID-19 outbreak. On June 8, 2020, the Company entered into an agreement with the U.S. Department of the Treasury to receive $16.4 million in emergency relief through the CARES Act Payroll Support Program to be paid in installments.

SIGNIFICANT RISKS AND UNCERTAINTIES
SIGNIFICANT RISKS AND UNCERTAINTIES - Impact of Coronavirus COVID-19	NOTE C — SIGNIFICANT RISKS AND UNCERTAINTIES Impact of Coronavirus (“COVID-19”) COVID-19 was declared a global health pandemic by the World Health Organization. In early March 2020, as AerSale began to see the impacts to its customers, the Company took decisive actions to position itself for the short-term impacts of COVID-19, while allowing the Company the flexibility to quickly pursue the opportunities that would follow. The Company cancelled approximately $20 million of feedstock opportunities under negotiation, as it evaluated the impacts of COVID-19 on asset valuations. The Company also reexamined its structure and executed measures in 2020 to adjust the business through strategic headcount reductions and suspension of various other initiatives, resulting in reduced costs of over $20 million on an annualized basis. ​ While the duration and extent of the COVID-19 pandemic depends on future developments that cannot be accurately predicted at this time, such as the extent and effectiveness of containment actions, and future restrictions due to different strains, or variants of COVID-19, it has already had an adverse effect on the global economy and the ultimate societal and economic impact of the COVID-19 pandemic remains unknown.

REVENUE
REVENUE	NOTE D — REVENUE The timing of revenue recognition, customer billings and cash collections results in a contract asset or contract liability at the end of each reporting period. Contract assets consist of unbilled receivables or costs incurred where revenue recognized over time exceeds the amounts billed to customers. Contract liabilities include advance payments and billings in excess of revenue recognized. Certain customers make advance payments prior to the satisfaction of performance obligations on the contract. These amounts are recorded as contract liabilities until such performance obligations are satisfied. Contract assets and contract liabilities are determined on a contract by contract basis. Contract assets are as follows (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2021 December 31, 2020 Change Contract assets ​ $ 14,912 ​ $ 20,431 ​ $ (5,519) ​ Contract assets are reported within accounts receivable on our condensed consolidated balance sheets. Changes in contract assets primarily results from the timing difference between our performance of services. Contract liabilities are reported as deferred revenue on our condensed consolidated balance sheets and amounted to $2.6 million as of December 31, 2020, of which $2.2 million was related to contract liabilities for services performed. For the three and nine months ended September 30, 2021, the Company recognized as revenue $0.6 million and $2.0 million of contract liabilities for services performed as the timing between customer payments and our performance of the services is generally no longer than six months.

BUSINESS SEGMENTS
BUSINESS SEGMENTS	NOTE L — BUSINESS SEGMENTS Consistent with how our chief operating decision maker (Chairman and Chief Executive Officer) evaluates performance and utilizes gross profit as a profitability measure, the Company reports its activities in two business segments: ● Asset Management Solutions — comprised of activities to extract value from strategic asset acquisitions through leasing, trading, or disassembling for product sales. ● Tech Ops — comprised of MRO activities; and product sales of internally developed engineered solutions and other serviceable products. The Asset Management Solutions segment provides short-term and long-term leasing solutions of aircraft and jet engines to passenger and cargo operators worldwide. Assets considered to be at or near the end of their useful lives, supplied by our leasing portfolio or acquisitions, are analyzed for return maximization to assess whether they will be traded as whole assets or disassembled and sold as individual spare parts and components. The Tech Ops segment consists of aftermarket support and services businesses that provide maintenance support for aircraft and aircraft components, and sale of engineered solutions. Our MRO business also engages in longer term projects such as aircraft modifications, cargo conversions of wide-body aircraft, and aircraft storage. The segment also includes MRO of landing gear, thrust reversers, and other components. Cost of sales consists principally of the cost of product, direct labor, and overhead. Our engineered solutions revenues consist of sales of products internally developed as permitted by Supplemental Type Certificates issued by the FAA. These products are proprietary in nature and function as non-original equipment manufacturer solutions to airworthiness directives and other technical challenges for operators. In order to develop these products, the Company engages in research and development activities. Periodically, the Company’s Tech Ops segment engages in the repair and sale of used serviceable materials through their ability to overhaul existing inventory. Gross profit is calculated by subtracting cost of sales from sales. The assets and certain expenses related to corporate activities are not allocated to the segments. Our reportable segments are aligned principally around the differences in products and services. The segment reporting excludes the allocation of selling, general and administrative expenses, interest expense and income tax expense.

BUSINESS COMBINATION
BUSINESS COMBINATION	NOTE N — BUSINESS COMBINATION On January 7, 2020 the Company acquired all of the outstanding shares of Aircraft Composite Technologies, Inc. (“ACT”), a Florida corporation located in Miami, Florida, for $17.0 million in cash. The results of ACT operations have been included in the condensed consolidated financial statements since the acquisition date. All assets and liabilities of ACT were recorded at their fair market value, and to the extent that the purchase cost exceeded the fair market value of the net assets, that excess was recorded as goodwill, all of which is deductible for federal income tax purposes. The goodwill is attributable to the general reputation of the business and the collective experience of ACT’s management and employees. This business operates as part of our Tech Ops segment. ACT’s revenues and income from operations for the three months ended September 30, 2020 were $1.3 million and $0.1 million, respectively, and from January 7, 2020 through September 30, 2020 were $5.3 million and $1.2 million, respectively.

STOCKHOLDERS' EQUITY
STOCKHOLDERS' EQUITY	NOTE O — STOCKHOLDERS’ EQUITY As AerSale Aviation was deemed the accounting acquirer in the Reverse Recapitalization with Monocle, all periods prior to the consummation date reflect the balances and activity of AerSale Aviation. The share activity (preferred stock and common stock) and per share amounts in the Consolidated Statements of Stockholders’ Equity as of December 31, 2019, from the previously reported audited consolidated financial statements of AerSale Aviation, were retroactively adjusted using the recapitalization exchange ratio of 74.0%. Common Stock Prior to the Merger, holders of AerSale Aviation’s common stock were entitled to one vote per share, and to receive dividends and, upon liquidation or dissolution, were entitled to receive all assets available for distribution to stockholders. The holders had no preemptive or other subscription rights and there were no redemption or sinking fund provisions with respect to such shares. Common stock was subordinated to the preferred stock with respect to dividend rights and rights upon liquidation, winding up, and dissolution of the Company. Upon the consummation of the Merger, holders of AerSale Aviation’s common stock received shares of the Company’s common stock at $10.00 per share as merger consideration. The Company’s common stock consist of $0.0001 par value, 200,000,000 shares authorized, of which 42,949,261 shares were issued and outstanding Earn-Out Shares Upon consummation of the Merger and in each case on or prior to the fifth anniversary of the Closing, the pre-closing holders of AerSale Aviation’s common stock and the holders of in-the-money SARs (as defined in the Merger Agreement) received a contingent right to receive up to 3,000,000 additional shares of the Company’s common stock. Additionally, certain pre-closing holders of AerSale Aviation’s common stock received a contingent right to receive 746,876 shares of the Company’s common stock. Effective February 8, 2021, the contingency event related to the Minimum Target Earn-Out Shares was met and 1,855,634 shares were issued. Subsequent to September 30, 2021, the contingent event related to the Maximum Target Earn-Out Shares was met and 1,854,169 shares were subsequently issued. The Company determined the Earn-Out Shares to be classified as equity under ASC Topic 815, “Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in a Company’s Own Stock” as the contingent right is indexed to the Company’s stock and accordingly, the accrual of the Earn-Out shares as of September 30, 2021 had no impact on the Company’s consolidated financial statements. Unvested Founder Shares Upon the Merger, certain pre-closing holders of AerSale Corporation’s common stock agreed to defer the vesting of an aggregate of 700,000 shares (the “Unvested Founder Shares”), half of which will vest at such time as the Minimum Target (as defined in the Merger Agreement) and the other half of which will vest at the Maximum Target (as defined in the Merger Agreement). Effective February 8, 2021, the contingency event related to the Minimum Target was met and half of the Unvested Founder Shares vested. Subsequent to September 30, 2021, the contingent event related to the Maximum Target was met and the other half of the Unvested Founder Shares vested. ​ 2020 Equity Incentive Plan The Company maintains a 2020 Equity Incentive Plan (the “2020 Plan”) and has registered 4,200,000 shares of common stock issuable under the Plan. The 2020 Plan authorizes discretionary grants of incentive stock options to employees of the Company and its qualifying subsidiaries. The 2020 Plan also authorizes discretionary grants of non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalents or other equity or cash-based awards to employees and consultants of the Company and its subsidiaries and to members of the Board of Directors of the Company. To the extent that an award under the 2020 Plan expires, is cancelled, forfeited, terminated, settled in cash or is otherwise settled without issuance of the full number of shares to which it relates, will become or again be available for awards under the 2020 Plan. The 2020 Plan is administered by the Company's Compensation Committee. The Compensation Committee has complete, full and final authority to: designate participants; determine the types of awards to be granted; determine the terms of awards; interpret and administer the 2020 Plans and any agreements and awards thereunder. Restricted stock unit activity under the 2020 Plan for the nine months ended September 30, 2021 was as follows ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted Average ​ ​ ​ ​ ​ Weighted Average ​ Remaining Contractual ​ Amount Grant Date Fair Value Life (Years) Outstanding at December 31, 2020 ​ ​ — ​ $ — ​ ​ — Granted ​ 1,702,280 ​ 10.10 ​ ​ 2.24 Forfeited ​ ​ (2,210) ​ 12.46 ​ ​ 2.40 Outstanding September 30, 2021 ​ ​ 1,700,070 ​ $ 10.10 ​ ​ 2.24 ​ The Company’s restricted stock units include 1,595,000 performance-based awards that have vesting provisions subject to both time vesting and the achievement of certain performance milestones, while the remaining 105,070 awards vest over a period ranging from one ​ For the restricted stock unit awards granted under the 2020 Plan containing both service and performance conditions, the Company recognizes compensation expense when the awards are considered probable of vesting. Restricted stock units are considered granted, and the service inception date begins, when a mutual understanding of the key terms and conditions between the Company and the employee have been established. The fair value of these awards is determined based on the closing price of the shares on the grant date. The probability of restricted share awards granted with future performance conditions is evaluated at each reporting period and compensation expense is adjusted based on the probability assessment. ​ For the three and nine months ended September 30, 2021, the Company recognized share-based compensation expense for the performance-based awards of $8.5 million, given that the achievement of the performance milestones have been deemed probable for accounting purposes. ​ 2020 Employee Stock Purchase Plan The Company also maintains a 2020 Employee Stock Purchase Plan (the “ESPP”) and has registered 500,000 shares of common stock issuable under the ESPP. The Company has not issued shares pursuant to the ESPP as of September 30, 2021.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Interim Financial Statements	Interim Financial Statements The accompanying unaudited interim consolidated financial statements have been prepared from the books and records of the Company in accordance with accounting principles Generally Accepted in the United States (“U.S. GAAP”) for interim financial information and Rule 10-01 of Regulation S-X promulgated by the U.S. Securities and Exchange Commission (“SEC”), which permits reduced disclosures for interim periods. Although these interim consolidated financial statements do not include all of the information and footnotes required for complete annual consolidated financial statements, management believes all adjustments, consisting only of normal recurring adjustments, and disclosures necessary for a fair presentation of the accompanying condensed consolidated balance sheets, statements of operations, stockholders’ equity, and cash flows have been made. Unaudited interim results of operations and cash flows are not necessarily indicative of the results that may be expected for the full year. Unaudited interim condensed consolidated financial statements and footnotes should be read in conjunction with the audited consolidated financial statements and footnotes included in Part II, Item 8 of the Annual Report
Revenue Recognition	Revenue Recognition Products — Used Serviceable Material Sales (“USM”) Revenues from sales of USM are measured based on consideration specified within customer contracts, and excludes any sales commissions and taxes collected and remitted to government agencies. The Company recognizes revenue when performance obligations are satisfied by transferring control of a product or service to a customer. The parts are sold at a fixed price with no right of return. In determining the performance obligation, management has identified the promise in the contract to be the shipment of the spare parts to the customer. Title passes to the buyer when the goods are shipped, the buyer is responsible for any loss in transit and the Company has a legal right to payment for the spare parts once shipped. The Company generally sells its USM products under standard 30-day payment terms, subject to certain exceptions. Customers neither have the right to return products nor do they have the right to extended financing. The Company has determined that physical acceptance of the spare parts to be a formality in accordance with Accounting Standards Codification (“ASC”) Topic 606, “Revenue from Contracts with Customers” (“ASC 606”). Spare parts revenue is based on a set price for a set number of parts as defined in the purchase order. The performance obligation is completed once the parts have shipped and as a result, all of the transaction price is allocated to that performance obligation. The Company has determined that it is appropriate to recognize spare parts sales at a point in time (i.e., the date the parts are shipped) in accordance with ASC 606. Products — Whole Asset Sales Revenues from whole asset sales are measured based on consideration specified in the contract with the customer. The Company and customer enter into an agreement which outlines the place and date of sale, purchase price, condition of the whole asset, bill of sale and the assignment of rights and warranties from the Company to the customer. The Company believes the whole asset holds standalone value to the customer as it is not dependent on any other services for functionality purposes and therefore is distinct within the context of the contract and as described in ASC 606-10. Accordingly, the Company has identified the transfer of the whole asset as the performance obligation. The transaction price is set at a fixed dollar amount per fixed quantity (number of whole assets) and is explicitly stated in each contract. Whole asset sales revenue is based on a set price for a set number of assets, which is allocated to the performance obligation discussed above, in its entirety. The Company has determined the date of transfer to the customer is the date the customer obtains control over the asset and would cause the revenue recognition. Payment is required in full upon a customer’s acceptance of the whole asset on the date of the transfer. Leasing Revenues The Company leases flight equipment under operating leases that contain monthly base rent and reports rental income straight line over the life of the lease as it is earned. Additionally, the Company’s leases provide for supplemental rent, which is calculated based on actual hours or cycles of utilization and, for certain components, based on the amount of time until maintenance of that component is required. In certain leases, the Company records supplemental rent paid by the lessees as maintenance deposit payment liabilities in recognition of the Company’s contractual commitment to reimburse qualifying maintenance. Reimbursements to the lessees upon receipt of evidence of qualifying maintenance work are charged against the existing maintenance deposit payments liabilities. In leases where the Company is responsible for performing certain repairs or replacement of aircraft components or engines, supplemental rent is recorded as revenue in the period earned. In the event of premature lease termination or lessee default on the lease terms, revenue recognition will be discontinued when outstanding balances are beyond the customers’ deposits held. Payment terms for leased flight equipment are due upon receipt. Service Revenues Service revenues are recognized as performance obligations when they are fulfilled and the benefits are transferred to the customer. At contract inception, the Company evaluates if the contract should be accounted for as a single performance obligation or if the contract contains multiple performance obligations. In some cases, the Company’s service contract with the customer is considered one performance obligation as it includes factors such as the good or service being provided is significantly integrated with other promises in the contract, the service provided significantly modifies or customizes the other good or service or the goods or services are highly interdependent or interrelated with each other. If the contract has more than one performance obligation, the Company determines the standalone price of each distinct good or service underlying each performance obligation and allocates the transaction price based on their relative standalone selling prices. The transaction price of a contract, which can include both fixed and variable amounts, is allocated to each performance obligation identified. Some contracts contain variable consideration, which could include incremental fees or penalty provisions related to performance. Variable consideration that can be reasonably estimated based on current assumptions and historical information is included in the transaction price at the inception of the contract but limited to the amount that is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. Variable consideration that cannot be reasonably estimated is recorded when known. For most service contracts, performance obligations are satisfied over time as work progresses based on transfer of control of products and services to our customers. The Company receives payments from our customers based on billing schedules or contract terms. For performance obligations that are satisfied over time, the Company measures progress in a manner that depicts the performance of transferring control to the customer. As such, the Company utilizes the input method of cost-to-cost to recognize revenue over time as this depicts when control of the promised goods or services are transferred to the customer. Revenue is recognized based on the relationship of actual costs incurred to date to the estimated total cost at completion of the performance obligation. The Company is required to make certain judgments and estimates, including estimated revenues and costs, as well as inflation and the overall profitability of the arrangement. Key assumptions involved include future labor costs and efficiencies, overhead costs and ultimate timing of product delivery. Differences may occur between the judgments and estimates made by management and actual program results. Under most of the Company’s Maintenance, Repair and Overhaul (“MRO”) contracts, if the contract is terminated for convenience, the Company is entitled to payment for items delivered, fair compensation for work performed, the costs of settling and paying other claims and a reasonable profit on the costs incurred or committed. Changes in estimates and assumptions related to our arrangements accounted for using the input method based on labor hours are recorded using the cumulative catchup method of accounting. These changes are primarily adjustments to the estimated profitability for our long term programs where the Company provides MRO services. The Company has elected to use certain practical expedients permitted under ASC 606. Shipping and handling fees and costs incurred associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost, are included in cost of sales in our condensed consolidated statements of operations and are not considered a performance obligation to our customers. The Company’s reported sales on our condensed consolidated statements of operations are net of any sales or related non income taxes. The Company also utilizes the “as invoiced” practical expedient in certain cases where performance obligations are satisfied over time and the invoiced amount corresponds directly with the value the Company is providing to the customer.
Revision of Prior Period Financial Statements	Revision of Prior Period Financial Statements During the nine months ended September 30, 2021, the Company identified and corrected immaterial errors that affected certain of its previously issued consolidated financial statements. These errors related to the misapplication of generally accepted accounting principles in the United States in connection with the classification of the Company’s private warrants as equity. The SEC released a Public Statement on April 12, 2021 noting that when one or more features common to warrants in SPAC transactions is included in a warrant, the warrant “should be classified as a liability measured at fair value, with changes in fair value each period reported in earnings.” Following review of the SEC’s statement, the Company concluded that its private warrants do not meet the conditions to be classified as equity and instead, the private warrants meet the definition of a derivative under ASC 815 “Derivatives and Hedging.” This requires the Company to record the private warrants as a liability measured at fair value on the Company’s Condensed Consolidated Balance Sheets with the changes in fair value each period reported in earnings. As a result, in the three and nine months ended September 30, 2021, the Company recorded $2.1 million and $2.7 million, respectively, reflected as change in fair value of warrant liability. Accordingly, the Company revised its December 31, 2020 financial statements by recognizing the private warrants as a liability upon the consummation of the Business Combination on December 22, 2020 in the amount of $1.2 million with a corresponding reduction to additional paid-in capital and retained earnings of $0.8 million and $0.4 million, respectively. ​ The Company determined the impact of the error related to the accounting treatment of private warrants had an immaterial impact with respect to the Company’s consolidated financial statements included in its Annual Report on Form 10-K for the year ended December 31, 2020. However, in order to correctly present the immaterial errors noted above, previously issued comparative financial statements have been revised as of the quarter ended March 31, 2021.
New Accounting Pronouncements Not Yet Adopted	New Accounting Pronouncements Not Yet Adopted In February 2016, the FASB issued ASU 2016-02 Leases (Topic 842), which generally requires companies to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet. In July 2018, FASB issued ASU No. 2018-10, “Codification Improvements to Topic 842, Leases” and ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements.” Although early adoption is permitted, the Company plans to adopt Topic 842 during the first quarter of 2022, on a modified retrospective basis. The Company is currently evaluating the impact this guidance will have on our consolidated financial statements and related disclosures. In June 2016, the FASB issued ASU No. 2016-13 (“ASU 2016-13”), “Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” In November 2018, FASB issued ASU No. 2018-19, “Codification Improvements to Topic 326, Financial Instruments — Credit Losses,” which amends the scope and transition requirements of ASU 2016-13. Topic 326 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported amount. Topic 326 will become effective for the Company beginning January 1, 2023, with early adoption permitted, on a modified retrospective basis. The Company is currently evaluating the impact this guidance will have on our consolidated financial statements and related disclosures.
Payroll Support Programs	​ Payroll Support Programs The Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law on March 27, 2020 and is intended to assist the economy by issuing a relief package to preserve jobs in industries adversely impacted by the COVID-19 outbreak. On June 8, 2020, the Company entered into an agreement with the U.S. Department of the Treasury to receive $16.4 million in emergency relief through the CARES Act Payroll Support Program to be paid in installments. The proceeds of these grants are recorded within accrued expenses when received and are recognized as payroll support program proceeds in the condensed consolidated statement of operations over the periods that the funds are intended to compensate. During the three months ended September 30, 2020, we recognized $6.3 million under the CARES Act Payroll Support Program. During the nine months ended September 30, 2021 and 2020, we recognized $3.7 million and $12.7 million under the CARES Act Payroll Support Program, respectively. As part of the Payroll Support Program Extension Law, we entered into a new agreement with the U.S. Department of the Treasury on March 4, 2021 for the receipt of relief funds of $5.5 million. No amounts were received or recognized under the Payroll Support Program Extension Law during the three months ended September 30, 2021. During the nine months ended September 30, 2021, we received and recognized $5.5 million in grant proceeds under the Payroll Support Program Extension Law. Pursuant to the American Rescue Plan Act of 2021 (“ARP”), we entered into a new agreement with the U.S. Department of the Treasury on April 16, 2021 for the receipt of relief funds of an additional $5.5 million. No amounts were received or recognized under the American Rescue Plan Act during the three months ended September 30, 2021. During the nine months ended September 30, 2021, we received and recognized $5.5 million in grant proceeds under the American Rescue Plan Act. ​ In connection with the financial assistance we have received under the Payroll Support Program, we are required to comply with certain provisions of the CARES Act, including the requirement that funds provided pursuant to the Payroll Support Program be used exclusively for the continuation of payment of employee wages, salaries and benefits and the requirement against involuntary terminations, furloughs and reductions in employee pay rates and benefits from the signing date of the Payroll Support Program agreement through September 30, 2021. In addition, we are subject to provisions prohibiting the repurchase of common stock and the payment of common stock dividends through September 30, 2022, as well as limitations on the payment of certain employee compensation through April 1, 2023. These restrictions may affect our operations and if we do not comply with these provisions, we may be required to reimburse up to 100% of any previously received relief funds. As of September 30, 2021, we have been in compliance with these provisions.
