Source: FR Y-9SP for June 30, 2026. Total consolidated assets covers the company and every subsidiary (Memoranda item 1, BHSP8519). The parent-only lines count the holding company itself, which carries its banks as an investment, and its net income is year to date. The form is filed semiannually, as of June 30 and December 31, so in March and September these are the last filed values. Parent-only ratios are not comparable with the consolidated FR Y-9C ratios of larger holding companies. Bank-level figures in the tables below come from each bank's own call report.
