SUFFOLK

SUFFOLK is a federal credit union headquartered in Medford, New York, serving 77,768 members with $2.03B in total assets and $1.37B in outstanding loans as of Q4 2025. Based on its five-factor composite, the institution earns a health score of 80/100 (Excellent), anchored by a net worth ratio of 8.50% — above the 7.0% threshold the NCUA uses to classify a credit union as "well capitalized" under Prompt Corrective Action rules. Charter #17914 operates under peer group Over $500M, a cohort of 749 similarly-sized institutions.

Loan book quality and earnings power round out the picture. The delinquency rate of 0.53% measures loans 60+ days past due against total loans outstanding — the peer group average for Over $500M credit unions sits at 0.874%, so this institution is running tighter than peers. Return on assets comes in at 0.00%, reflecting the not-for-profit cooperative model where surplus earnings flow back to members as better rates and lower fees rather than to shareholders. The loan-to-share ratio of 76.82% indicates how aggressively member deposits are being deployed into lending — within the 60–80% range most industry analysts consider optimally balanced between yield and liquidity.

Every deposit account at SUFFOLK is federally insured by the National Credit Union Share Insurance Fund (NCUSIF) up to $250,000 per depositor, per ownership category — identical coverage to FDIC insurance at banks. Year-over-year membership changed by 4.44%, and the institution reports against the NCUA 5300 Call Report on a quarterly cadence, so the figures above reflect the 2025Q4 reporting period.
