Revenue Recognition

Products — Used Serviceable Material (“USM”) Sales

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 payment 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 beyond the customers’ deposits are 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 contractual 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.

Payroll Support Programs

The Company has also taken steps to improve our liquidity, including seeking financial assistance under the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”). Certain of the Company’s subsidiaries have received $16.4 million from the U.S. Treasury Department (“Treasury”) through the Payroll Support Program under the CARES Act, of which $3.7 million was received and recognized as payroll support program proceeds during the six months ended June 30, 2021. No amount was received or recognized under the CARES Act during the quarter ended June 30, 2022.

​

As part of the Payroll Support Extension Law, the Company entered into an agreement with the Treasury on March 4, 2021 for the receipt of relief funds of $5.5 million. During the six months ended June 30, 2021, we received $5.5 million in grant proceeds under the Payroll Support Extension Law. During the three- and six- month periods ended June 30, 2021, $2.9 million and $5.5 million was recognized as payroll support program proceeds in the condensed consolidated statements of operations.

​

Pursuant to the American Rescue Plan Act of 2021 (“ARP”), we entered into an agreement with the Treasury on April 16, 2021 for the receipt of relief funds of an additional $5.5 million. This amount was recognized during the three- and six- month periods ended June 30, 2021.

​

In connection with the financial assistance the Company has received under the Payroll Support Program, it is 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; the requirement against involuntary terminations and furloughs and reductions in employee pay rates and benefits from the signing date of the Payroll Support Program agreement through September 30, 2021. The agreement requires the

Company to issue a recall to any employee who was terminated or furloughed between October 1, 2020 and March 4, 2021 and enable such employee to return to employment. In addition, the Company is 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 the Company’s operations and if the Company does not comply with these provisions, it may be required to reimburse up to 100% of any previously received relief funds. In particular, limitations on compensation may adversely impact our ability to attract and retain senior management or attract other key employees during this critical time. As of June 30, 2022, we were in compliance with all applicable provisions of the CARES Act, Payroll Support Program and ARP.
