Employee Benefit and Retirement Plans EMPLOYEE BENEFIT AND RETIREMENT PLANS    
We sponsor defined benefit pension plans in the U.S. and certain foreign locations. In addition, we sponsor defined contribution plans in the U.S. We also contribute to defined contribution plans in locations outside the U.S., including government-sponsored retirement plans. We also currently provide postretirement medical and life insurance benefits to certain U.S. employees and retirees. We previously froze the accrual of future benefits under certain defined benefit pension plans in the U.S. and certain foreign locations. Although our defined benefit plans in the U.S., United Kingdom and Canada have generally been frozen, employees who are participants in the plans retained benefits accumulated up to the date of the freeze, based on credited service and eligible earnings, in accordance with the terms of the plans.
The following table presents the components of our pension (income) and other postretirement benefits expense for the three months ended May 31, 2024 and 2023 (in millions):
