We place receivables on non-accrual status when events, such as a customer’s declaring bankruptcy, occur that indicate a receivable will not be collectable. We charge off uncollectable financing receivables when we stop pursuing collection. As of March 31, 2017 we had a balance outstanding as of $3.2 million for a customer in bankruptcy which was fully reserved and on a non-accrual status. We wrote off this balance against the reserve for credit losses during the nine months ended December 31, 2017, after the bankruptcy case was substantially complete.

The age of the recorded minimum lease payments and net credit exposure associated with our investment in direct financing and sales-type leases that are past due disaggregated based on our internally assigned credit quality rating (“CQR”) were as follows as of December 31, 2017 and March 31, 2017 (in thousands):

	31-60 Days Past Due		61-90 Days Past Due		Greater than 90 Days Past Due		Total Past Due		Current		Unbilled Minimum Lease Payments		Total Minimum Lease Payments		Unearned Income			Non- Recourse Notes Payable			Net Credit Exposure

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.
