About these numbers
Figures come from the NCUA 5300 Call Report quarterly data for Q2 2026 (quarter ended June 30, 2026), which each credit union files itself. "60+ days late" is delinquent loans of two months or more divided by total loans. Peer medians are computed across every credit union in the same NCUA asset-size group.
