Watch flags
The net worth ratio is between 6% and 7%, adequately capitalized but below the 7% level NCUA considers well capitalized. Worth monitoring, not yet a PCA trigger. NCUA well-capitalized threshold, 12 CFR 702.102.
The credit union posted negative net income relative to assets in its latest filing. Credit unions build net worth only through retained earnings, so sustained losses gradually weaken capital. BankRegReports flag, negative earnings.
How we read these figures
Glossary: net worth ratio, delinquency, ROA, loan-to-share. The net worth category is ours, from NCUA's 7% well and 6% adequately capitalized cutoffs. It is not NCUA's determination, which can differ. ROA, ROE and margin annualize the quarter; NCUA's Financial Performance Report annualizes the year to date (YTD).
