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. 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

Automated conditions triggered on this bank's latest filing. Advisory only; see the source metric pages for full context. Each flag is tagged Regulatory when it cites an official supervisory threshold, or BRR analysis when it's our own band, informed by our data and models.
Loans outstanding are at or above total deposits. The bank reports little borrowing or brokered funding, so the difference is carried mainly by equity and other liabilities. Worth watching if loan growth continues to outpace deposits. Industry heuristic, not a supervisory threshold.
Commercial real estate loans exceed 300% of total capital, the threshold at which the 2006 interagency guidance flags a bank for heightened supervisory scrutiny. CRE concentration has been the central stress vector for regional banks since 2023. 2006 Interagency CRE Concentration Guidance (SR 07-1).
