Size & Membership
Profitability
Q2 annualizedROA, ROE and net interest margin are the quarter's own income, annualized. NCUA's Financial Performance Report annualizes the year to date instead, so after the first quarter its figures differ from ours. Where the 5300 for this quarter and the prior year-end is served, the year-to-date value on NCUA's basis is shown beside each as YTD, over the average of this quarter's and the prior year-end balances. NCUA publishes no ROE; ours uses the same year-to-date basis over average net worth.
Capital & Asset Quality
Net worth category is computed by BankRegReports from the net worth ratio, using NCUA's 7, 6, 4 and 2 percent thresholds. It is not NCUA's determination, which can differ.
