Its five-factor composite puts the health score at 88/100 (Excellent), driven in part by a net worth ratio of 14.29% - above the 7.0% NCUA "well capitalized" threshold under Prompt Corrective Action rules. It carries charter #13121 and reports within peer group $100M–$500M, a cohort of 1069 similarly-sized institutions.
Deposits deployed into lending sit at a 60.92% loan-to-share ratio, within the 60-80% range most industry analysts consider optimally balanced between yield and liquidity. Loan quality, meanwhile, shows 0.54% of the book 60+ days past due - the peer group average for $100M–$500M credit unions sits at 0.894%, so this institution is running tighter than peers. Return on assets stands at 0.23% on net income of $1.1M for the period; a not-for-profit cooperative typically runs a modest positive ROA, returning surplus to members through better rates and lower fees rather than to shareholders.
Year-over-year membership changed by 0.29%. All of the above reflects the 2025Q4 quarterly NCUA 5300 Call Report. Who can join depends on the field of membership (currently: Community); our disclaimer covers NCUSIF deposit-insurance coverage and how to use this data responsibly.
