In a regulatory filing on Thursday, Capital One said the annualized net charge-off rate -- debts the company believes it will never collect -- for U.S. credit cards had risen to 9.77 percent in September from 9.32 percent in August. Accounts at least 30 days delinquent -- an indicator of future loan losses -- increased to 5.38 percent from 5.09 percent. For U.S. auto loans, Capital One's charge-off rate went up to 4.58 percent in September from 4.31 percent in August, and the delinquency rate inched up to 9.52 percent from 9.42 percent. In international operations, including Canada and Britain, the charge-off rate rose to 9.24 percent in September from 8.60 percent in August, but the delinquency rate fell to 6.63 percent from 6.67 percent.
