Other Post-Employment Benefits and Other Employee Benefit Plans

In addition to providing pension benefits, we provide for a portion of healthcare, dental, vision and life insurance benefits for certain retired legacy Diversey employees, primarily in North America. Covered employees retiring on or after attaining age 55 and who have rendered at least 10 years of service are entitled to post-retirement healthcare, dental and life insurance benefits. These benefits are subject to deductibles, co-payment provisions and other limitations.

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:

Healthcare Cost Trend Rates

For the year ended December 31, 2017, healthcare cost trend rates were assumed to be 6.8% for the U.S. plan in 2017 and decreasing to 5.0% by 2022, and 5.0% for the Canada plan in 2017, and unchanged in future years. The assumed healthcare cost trend rate has an effect on the amounts reported for the healthcare plans. A one percentage point change on assumed healthcare cost trend rates would have the following effect for the year ended December 31, 2017:
