Allowance for Doubtful Accounts

Our two finance receivables portfolio segments, retail and wholesale, each consist of one class of receivable based on: (i) initial measurement attributes of the receivables, and (ii) the assessment and monitoring of risk and performance of the receivables. For more information, see Note 4, Finance Receivables.

The accrual of interest income is suspended on certain impaired finance receivables. Impaired finance receivables include accounts with specific loss reserves and certain accounts that are on non-accrual status. In certain cases, we continue to collect payments on our impaired finance receivables.
