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).
