Discover credit-card write-offs increased to 9.16 percent

Discover Financial Services, the credit-card company that took $1.2 billion from the Treasury Department's rescue fund, said defaults rose in August.

Charge-offs for loans deemed uncollectible climbed to 9.16 percent, compared with 8.43 percent in July, the Riverwoods-based lender said today in a federal filing.

Payments at least 30 days overdue, an indicator of future losses, advanced to 5.35 percent from 5.28 percent.
