“Banking institutions” are defined as financial institutions that are legally allowed to accept monetary deposits from consumers. Audit Analytics’ Bank Holding Companies database collects records dating back to 2005 and covers all banking institutions that file Forms FR Y-9C, FR Y-9LP or FR Y-9SP. This database provides information on who audits banking institutions as well as several other key data points, including assets, revenue, geographical data, and accounting and legal fees.
