(1) The short term and long term portion of the Officer Medical Plan’s benefit obligation is included in accrued compensation and other long-term liabilities, respectively, in the accompanying consolidated balance sheets.
The net actuarial gain related to the benefit obligation in fiscal 2026 was primarily driven by an increase in interest rates, partially offset by unfavorable changes in medical trends. The net actuarial loss related to the benefit obligation in fiscal 2025 was primarily due to unfavorable updates in estimated medical claims and medical inflation, partially offset by an increase in the discount rate. The net actuarial loss related to the benefit obligation in fiscal 2024 was primarily due to unfavorable updates in estimated medical claims, medical inflation, and demographic assumptions, partially offset by increases in discount rate.
The expected future medical benefit payments and related contributions are as follows:
