2. Revenue from Contracts with Customers

As of January 1, 2018, the Company adopted ASU 2014-09 and all subsequent ASUs that modified ASC 606. While only a portion of the Company’s revenues is impacted by this guidance as it does not apply to contracts falling under the leasing standard, as part of the implementation process the Company performed an analysis to identify accounting policies that needed to change and additional disclosures that are required. The Company considered factors such as customer contracts with unique revenue recognition considerations, the nature and type of goods and services offered, the degree to which contracts include multiple performance obligations or variable consideration, and the pattern in which revenue is currently recognized, among other things. All revenue streams applicable to the new standard (Spare parts and equipment sales and Managed services which is reflected within Other revenue) were evaluated by management. The Company considered recognition under the new standard and concluded the timing of the Company’s revenue recognition will remain the same. The Company has also evaluated the changes in controls and processes that are necessary to implement the new standard, and no material changes were required.

(1)

Represents revenue generated between our reportable segments.

(2)

Leasing revenue is recognized under the lease accounting guidance in ASC 840 Leases, and therefore qualifies for the scope exception under ASC 606.

(3)

Gain on sale of leased equipment is accounted for under ASC 610-20, Gains and losses from the derecognition of nonfinancial assets.

Leasing revenue

Revenue from leasing of engines, aircraft and related parts and equipment is recognized as operating lease revenue on a straight-line basis over the terms of the applicable lease agreements. Revenue is not recognized when cash collection is not reasonably assured. When collectability is not reasonably assured, the customer is placed on non-accrual status and revenue is recognized when cash payments are received.

Under the terms of some of the Company’s leases, the lessees pay use fees (also known as maintenance reserves) to the Company based on usage of the leased asset, which are designed to cover expected future maintenance costs. Some of these amounts are reimbursable to the lessee if they make specifically defined maintenance expenditures. Use fees received are recognized in revenue as maintenance reserve revenue if they are not reimbursable to the lessee. Use fees that are reimbursable are recorded as a maintenance reserve liability until they are reimbursed to the lessee or the lease terminates, at which time they are recognized in revenue as maintenance reserve revenue.

Certain lessees may be significantly delinquent in their rental payments and may default on their lease obligations. As of June 30, 2018, the Company had an aggregate of approximately $4.1 million in lease rent and $3.5 million in maintenance reserve receivables more than 30 days past due. Inability to collect receivables or to repossess engines or other leased equipment in the event of a default by a lessee could have a material adverse effect on the Company. The Company estimates an allowance for doubtful accounts for lease receivables it does not consider fully collectible. The allowance for doubtful accounts includes the following: (1) specific reserves for receivables which are impaired for which management believes full collection is doubtful; and (2) a general reserve for estimated losses based on historical experience.

Gain on sale of leased equipment

The Company regularly sells equipment from its lease portfolio. This equipment may or may not be subject to a lease at the time of sale. The gain or loss on such sales is recognized as revenue and consists of proceeds associated with the sale less the net book value of the asset sold and any direct costs associated with the sale. To the extent that deposits associated with the engine are not included in the sale, any such amount is included in the calculation of gain or loss.

Spare parts sales

The Spare Parts Sales reportable segment primarily engages in the sale of aircraft engine parts and materials through the acquisition or consignment of engines from third parties. The parts are sold at a fixed price with no right of return and are shipped “FOB shipping point.” In determining the performance obligation, management has identified the promise in the contract to be the shipment of the spare parts to the customer. When the spare parts are shipped FOB shipping point, title passes to the buyer when the goods are shipped, and the buyer is responsible for any loss in transit, and the Company has a legal right to payment for the spare parts. Management has determined that physical acceptance of the spare parts to be a formality in accordance with ASC 606-10-5-86 and as the Company is not obliged to perform additional services under these arrangements, the shipment of the spare parts is the performance obligation.

The spare parts transaction price is a fixed dollar amount and is stated on each purchase order for a fixed amount by total number of parts. Spare parts revenue is based on a set price for a set number of parts as defined in the purchase order. There is one performance obligation identified, as discussed above, which is the shipment of the parts and as a result, all of the transaction price is allocated to that performance obligation. Management has determined that it is appropriate for the Company to recognize spare parts sales at a point in time (i.e., on the shipment date) under ASC 606. Additionally, there is no impact to the timing and amounts of revenue recognized for spare parts sales related to the implementation of ASC 606.

Equipment Sales

Equipment sales represent the selective purchase and resale of commercial aircraft engines and other aircraft equipment. The Company and customer enter into an agreement which outlines the place and date of sale, purchase price, payment terms, condition of the asset, bill of sale, and the assignment of rights and warranties from the Company to the customer. Management has identified the promise in the equipment sale contract to be the transfer of ownership of the asset. Management believes the 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. As such, management has identified the transfer of the asset as the performance obligation. The transaction price is set at a fixed dollar amount per fixed quantity (number of assets) and is explicitly stated in each contract. Equipment 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 to be the date the customer obtains control and title over the asset and the date which revenue is to be recognized and payment is due. As such, there is no impact to the timing and amounts of revenue recognized for equipment sales related to the implementation of ASC 606.

Managed Services

Managed Services revenue predominantly represents fleet management and engine storage services which may be combined on a single contract with a customer. Fleet management services are performed for a stated fixed fee as agreed upon in the services agreement. Engine storage services are for a fixed monthly fee. For a contract containing more than one performance obligation, the allocation of the transaction price is generally performed on the basis of the relative stand-alone selling price of each distinct good or service in the contract. The result of allocation consideration on this basis is consistent with the overall core principal of ASC 606 (to recognize revenue in an amount that depicts the consideration to which the Company expects to be entitled in exchange for the promised goods or services). As each of the services provided within the contract have separate prices, the Company allocates the stated price to its related performance obligation described above. Management has determined each of the revenue elements contain performance obligations that are satisfied over time and therefore recognizes revenue over time in accordance with ASC 606-10-25-27. The company will continue utilizing the percentage-of-completion method (input method) for recognizing Fleet Management services and will calculate revenues based on labor hours incurred. Additionally, as is required by ASC 606-10-25-35, as circumstances change over time, the Company will update its measure of progress to reflect any changes in the outcome of the performance obligation. Engine storage services will continue to be recognized on a monthly basis utilizing the input method of days passed. Therefore, there is no impact to the timing and amounts of revenue recognized for Managed Services related to the implementation of ASC 606.

Amounts owed for Managed services are typically billed upon contract completion. At January 1, 2018, $0.4 million of unbilled revenue associated with outstanding contracts was reported in Other Assets, all of which was recognized by June 30, 2018. At June 30, 2018, unbilled revenue was $0.7 million and the Company expects it to be fully recognized by December 31, 2018. Additionally, Managed services are presented within the Other revenue line in the condensed consolidated statements of income.
