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.
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.
