Trade receivables consist primarily of receivables from financial institutions, which provide funding for customer boat financing and amounts due from financial institutions earned from arranging financing with our customers. We normally collect these receivables within 30 days of the sale. Trade receivables also include amounts due from customers on the sale of boats, parts, service, and storage. Amounts due from manufacturers represent receivables for various manufacturer programs and parts and service work performed pursuant to the manufacturers’ warranties.

The allowance for uncollectible receivables, which was not material to the consolidated financial statements as of September 30, 2019 or 2020, was based on our consideration of customer payment practices, past transaction history with customers, and economic conditions. When an account becomes uncollectable, we expense it as a bad debt and we credit payments subsequently received to the bad debt expense account. We review the allowance for uncollectible receivables when an event or other change in circumstances results in a change in the estimate of the ultimate collectability of a specific account.
