ALEXANDRIA, Va. — According to NCUA data, the ten credit unions with the highest percentage of their assets in credit card receivables have overall assets of $37.0 million or less.

The three credit unions whose card receivables make up the highest percentage of their overall assets are the $37.0 million Acme Continental (30.5% from cards) headquartered in Riverdale, Illinois; the $4.9 million Snake River Federal Credit Union (23.2% from cards), headquartered in Twin Falls, Idaho; and the $19.0 million Bridgeport Fire Department Employees Federal Credit Union (21.3% from cards) headquartered in Bridgeport, Connecticut.

To some extent, this is not surprising. Credit card receivables would naturally be a bigger part of an overall smaller credit union. But despite their smaller overall size, these credit unions strongly manage their card programs, often using innovation and reputation to keep their cards at the top of their members' wallets.
