We place receivables on non-accrual status when events, such as a customer’s declaring bankruptcy, occur that indicate a receivable will likely not be collectable. We charge off uncollectable financing receivables when we stop pursuing collection.

We estimate losses on our net credit exposure to be between 0% - 5% for customers with highest CQR, as these customers are investment grade or the equivalent of investment grade. We estimate losses on our net credit exposure to be between 2% - 15% for customers with average CQR, and between 15% - 100% for customers with low CQR, which includes customers in bankruptcy.
