- Unusual Items: Q1 2025 included a one-time tax expense of $166k related to BOLI policy surrenders, which impacted the effective tax rate for that period. Q1 2026 included a $131k gain from a BOLI death benefit.
Investor Verification Checklist
- Loan Concentration: Verify the specific exposure to the "Investment and development" and "Hotels" sectors within the commercial real estate portfolio, which represent significant portions of the CRE book.
- Deposit Stability: Monitor the trend of noninterest-bearing demand deposits, which declined $15.1 million in the quarter, potentially indicating a shift in customer behavior or competitive pressure.
- AFS Securities: Review the $10.6 million in net unrealized losses on Available-for-Sale (AFS) securities and the impact on tangible book value ($1.17 reduction per share).
- Provision Trends: Assess the sustainability of the $604k provision for credit losses given the increase in net charge-offs compared to the prior year's recoveries.
- Regulatory Capital: Confirm that the "well capitalized" status is maintained as the company continues to grow its loan portfolio and manage interest rate risk.
