In addition to providing pension benefits, we maintain two Other Post-Employment Benefit Plans which provide a portion of healthcare, dental, vision and life insurance benefits for certain retired legacy employees. These plans are in the U.S. and Canada. Covered employees who retired on or after attaining age 55 and who had rendered at least 10 years of service were

entitled to post-retirement healthcare, dental and life insurance benefits. These benefits are subject to deductibles, co-payment provisions and other limitations. The information below relates to these two plans.

Contributions made by us, net of Medicare Part D subsidies received in the U.S., are reported below as benefits paid. We may change the benefits at any time. The status of these plans, including a reconciliation of benefit obligations, a reconciliation of plan assets and the funded status of the plans, follows:

Actuarial gains resulting in a decrease to our accumulated benefit obligation for the year ended December 31, 2023 were primarily due to a decrease in expected utilization of employer funded portions of retiree medical savings accounts. This change was based on an analysis of actual historical utilization rates over the last five years. Actuarial gains resulting in a decrease to our accumulated benefit obligation for the year ended December 31, 2022 were primarily due to an increase in the weighted average discount rate of 270 basis points. The accumulated post-retirement benefit obligations were determined using a weighted-average discount rate of 5.1% at December 31, 2023 and 5.4% at December 31, 2022.

The amortization of any prior service credit is determined using a straight-line amortization of the credit over the average remaining service period of employees expected to receive benefits under the plan. Changes in benefit obligations that were recognized in AOCL for the years ended December 31, 2023 and December 31, 2022 were as follows:

The assumed healthcare cost trend rates have an effect on the amounts recognized in our Consolidated Statements of Operations for the healthcare plans. For the year ended December 31, 2023, healthcare cost trend rates were assumed to be 7.0% for the U.S. plan and 5.0% for the Canada plan. The trend rates assumed for 2024 are 6.8% and 5.0% for the U.S. and Canada plan, respectively. Rates are expected to decrease to 5.5% by 2029 for the U.S. plan, and remain unchanged in future years for the Canada plan.
