Balance Sheet
Income Statement
Operating & Funding
Rows tagged YTD are fiscal year to date through June 30, 2026, as filed. Net income is tagged Q2 because it is that quarter's own figure, not a running total, so it cannot be compared with a YTD row. This bank files the community bank leverage ratio (CBLR), the simplified capital framework for qualifying community banks. It does not report CET1, Tier 1 or total risk-based ratios, so the Tier 1 leverage ratio is the capital measure that applies.
Quarterly trends
Last 12 quarters from this bank's own FFIEC call reports. Dollar figures are the quarter's own amount: the income statement is filed year to date, so those lines are shown net of the preceding quarter.
Balances at each quarter end. The gap between the two lines is equity capital.
Balances at each quarter end. Loans rising toward deposits is the loan-to-deposit ratio tightening.
Balances at each quarter end. Each line is its own balance, not stacked on the other.
Each bar is that quarter alone. The gap between the two is net interest income.
What the balance sheet earned on spread that quarter, before fees and operating costs.
Fees, trading and other income against salaries, premises and the rest of the cost base.
What the bank charged to earnings that quarter to build its allowance for expected losses.
The quarter's own net income, as filed. It needs no adjustment because the filing does not accumulate it through the year.
CET1 is common equity tier 1 as a share of risk-weighted assets; the leverage ratio is tier 1 capital as a share of average total assets. A bank that files the community bank leverage ratio reports no CET1 ratio, so only its leverage line appears.

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).

Quarter-over-quarter movement in the five most-watched ratios. Sourced from the bank's own FFIEC call report filings. A community bank leverage ratio filer reports no CET1 ratio, so the first ratio column is the Tier 1 leverage ratio.
