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, The First Security Bank reports no risk-based capital ratios; its Tier 1 leverage ratio applies. How we compute these figures

Watch flags

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.

Loan-to-Deposit at 105.0%, loans exceed deposit base BRR analysis What does this mean? →

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.
