Capital One Delinquency and Default Rates Drop

More Capital One credit card customers paid their bills on time last month.

The issuer's delinquency rate--the percentage of accounts 30 or more days overdue--on U.S. cards declined in December, from 3.71 percent in November to 3.61 percent in December. The December number was also below October's figure of 3.66 percent.

In addition, the charge off rate--the accounts that Capital One does not expect to collect--also dropped from 4.46 percent in November to 4.35 percent in December. The October charge-off rate was 4.25 percent.
