The income tax expense differs from the amount computed by applying the U.S. Federal income tax rate of 21% for 2025, 2024, and 2023 to income before income taxes. There were no activities or transactions that had foreign income taxes or cross-border tax effects during 2025, 2024, or 2023. State income/franchise taxes are primarily related to the States of Texas and Oklahoma. Included in the table below is the net tax benefit related to investments in LIHTC projects. Additional information on LIHTC investments can be found in Note 2 – Investment Securities, Equity Securities with

About Income Taxes Disclosures
The income tax disclosure reveals how much a company actually pays in taxes versus what the statutory rate would predict. Analysts focus on the effective tax rate (ETR) reconciliation, which breaks down every item driving the gap between the 21% federal rate and the company's reported ETR — including R&D credits, foreign rate differentials, and state taxes. Deferred tax assets (DTAs) and their valuation allowances signal management's confidence in future profitability: a rising allowance suggests the company doubts it can use accumulated tax benefits. Uncertain tax benefit (UTB) reserves quantify exposure to IRS challenges on aggressive positions.
Key signals to watch: sudden ETR drops without clear operational reasons, large increases in valuation allowances, growing UTB balances, and significant unremitted foreign earnings. Post-TCJA, pay attention to GILTI and BEAT provisions that affect multinational tax structures. Compare the cash taxes paid (from the cash flow statement) against the income tax provision to gauge earnings quality.
