Method
Banks are FDIC-insured institutions headquartered in Iowa with a call report for the quarter ending 06/30/2026. Return on assets and net interest margin are annualized year to date; the efficiency ratio is noninterest expense over revenue, so lower is better. Credit unions are NCUA-insured and not included.
