The majority of our revenue is from contracts with customers for the sale of boats, motors, and trailers. We recognize revenue from boat, motor, and trailer sales upon transfer of control of the boat, motor, or trailer to the customer, which is generally upon acceptance or delivery to the customer. At the time of acceptance or delivery, the customer is able to direct the use of, and obtain substantially all of the benefits of the boat, motor, or trailer at such time. We recognize commissions earned from a brokerage sale when the related brokerage transaction closes upon transfer of control of the boat, motor, or trailer to the customer, which is generally upon acceptance or delivery to the customer.

We do not directly finance our customers’ boat, motor, or trailer purchases. In many cases, we assist with third-party financing for boat, motor, and trailer sales. We recognize commissions earned by us for placing notes with financial institutions in connection with customer boat financing when we recognize the related boat sales. Pursuant to negotiated agreements with financial institutions, we are charged back for a portion of these fees should the customer terminate or default on the related finance contract before it is outstanding for a stipulated minimum period of time. We base the chargeback allowance, which was not material to the unaudited condensed consolidated financial statements taken as a whole as of March 31, 2019, on our experience with repayments or defaults on the related finance contracts. We recognize variable consideration from commissions earned on extended warranty service contracts sold on behalf of third-party insurance companies at generally the later of customer acceptance of the service contract terms as evidenced by contract execution or recognition of the related boat sale. We also recognize variable consideration from marketing fees earned on insurance products sold by third-party insurance companies at the later of customer acceptance of the insurance product as evidenced by contract execution or when the related boat sale is recognized.

We recognize revenue from parts and service operations (boat maintenance and repairs) over time as services are performed. Each boat maintenance and repair service is a single performance obligation that includes both the parts and labor associated with the service. Payment for boat maintenance and repairs is typically due upon the completion of the service, which is generally completed within a short period of time from contract inception. We satisfy our performance obligations, transfer control, and recognize revenue over time for parts and service operations because we are creating a contract asset with no alternative use and we have an enforceable right to payment for performance completed to date. Contract assets primarily relate to our right to consideration for work in process not yet billed at the reporting date associated with maintenance and repair services. We use an input method to recognize revenue and measure progress based on labor hours expended to satisfy the performance obligation at average labor rates. We have determined labor hours expended to be the relevant measure of work performed to complete the maintenance and repair service for the customer. As a practical expedient, since repair and maintenance service contracts have an original duration of one year or less, we do not consider the time value of money, and we do not disclose estimated revenue expected to be recognized in the future for performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period or when we expect to recognize such revenue. Contract assets, recorded in Prepaid expenses and other current assets, totaled approximately $2.7 million and $3.1 million as of October 1, 2018 (beginning of the period of adoption of ASC 606) and March 31, 2019, respectively.

We recognize deferred revenue from service operations and slip and storage services over time on a straight-line basis over the term of the contract as our performance obligations are met. We recognize income from the rentals of chartering power and sailing yachts over time on a straight-line basis over the term of the contract as our performance obligations are met.
