San Diego County Credit Union’s membership grew nearly 9 percent to 295,000 customers in the year ending June 30, the credit union said in its quarterly earnings report.

SDCCU’s return on assets was 1.3 percent for the second quarter, with assets of $6.9 billion. The credit union reported the same level of assets last quarter.

The credit union’s net-worth-to-assets ratio, a measure of the strength of an institution’s capital, was 13.71 percent, nearly double the 7 percent minimum for well-capitalized credit unions according to federal regulators.

SDCCU is the county’s largest locally-owned financial institution, the credit union said.
