(4) Income Taxes

On July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was signed into law. The OBBBA makes permanent key elements of the Tax Cuts and Jobs Act of 2017, including 100% bonus depreciation. The OBBBA did not have a material impact on the Company’s effective income tax rate for 2025, but it did reduce the Company’s cash tax outflows in 2025 from what they would have been under the previous federal tax law.

Income tax expense for the years ended December 31 was as follows:

The Company’s federal income tax returns for the year ended December 31, 2022 and subsequent years remain subject to examination.

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.
