Ratios tagged annualized use the Q2 income alone. The UBPR and FDIC annualize the year to date instead. FDIC BankFind divides by the average of quarter-end total assets, the UBPR by RC-K average assets. The YTD margin is the UBPR's tax-equivalent figure over its own average earning assets; FDIC BankFind's margin is not tax-equivalent. As a community bank leverage ratio filer, First Southern Bank reports no risk-based capital ratios; its Tier 1 leverage ratio applies. How we compute these figures
