. However, the net impact of any changes in the expected return on benefit plan assets on the final benefit cost recognized for fiscal year 2025 would be $0 since the actual return on assets would effectively be reflected at December 31, 2025, under our mark-to-market accounting methodology.

•The present value of pension obligations is calculated by discounting long-term obligations using a market interest rate. This discount rate is the estimated rate at which the benefit obligations could be effectively settled on the measurement date and is based on yields of high quality fixed income investments whose cash flows match the timing and amount of expected benefit payments of the plan. Discount rates of approximately 5.65% were used as of December 31, 2024. A one-half percentage point reduction in the discount rate would increase the valuation of pension benefit obligations by $1.7 million and postretirement health and life benefit obligations by $3.3 million, and the resulting changes in the valuations would decrease the aggregate service cost and interest cost components of annual pension costs and postretirement health and life benefit costs by $0 and $0.2 million, respectively. 

•The healthcare costs trend rates are 7% projected in 2025 reducing to a final trend rate of 5% by 2033. The healthcare costs trend rate represents our estimate of the annual rate of increase in the gross cost of providing benefits. The trend rate is a reflection of health care inflation assumptions, changes in healthcare utilization and delivery patterns, technological advances, and changes in the health status of our plan participants.

Income Taxes

During the ordinary course of business, there are transactions and calculations for which the ultimate tax determination is uncertain. As a result, we recognize tax liabilities based on estimates of whether additional taxes and interest will be due. To the extent that the final tax outcome of these matters is different than the amounts that were initially recorded, such differences will impact the income tax provision in the period in which such determination is made.

Accounting standards prescribe a minimum recognition threshold that a tax position is required to meet before the related tax benefit may be recognized in the financial statements. As of December 31, 2024, the liability for unrecognized tax benefits, included in Other Long-Term Liabilities on the Consolidated Balance Sheet in Part IV of this Annual Report, was $3.4 million and accrued interest and penalties totaled $0.5 million.

Accounting for income taxes involves estimates and judgments relating to the tax bases of assets and liabilities and the future recoverability
