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, wherein a more complete discussion of significant accounting policies and certain other information can be found.

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.
