Profitability
Q2 annualizedCapital & Liquidity
Balance Sheet
Income Statement
Operating & Funding
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. After a merger that grows assets 25% or more, the UBPR averages balances from the merger date on while the income stays year to date, so a YTD ratio can differ widely from the ratio of either quarter. The YTD margin is the UBPR's tax-equivalent figure over its own average earning assets; FDIC BankFind's margin is not tax-equivalent. How we compute these figures
