For 2022, no pension contributions are required for our tax-qualified U.S. domestic pension plans (“U.S. Pension Plans”) as they are fully funded under the Employee Retirement Income Security Act. We made no voluntary contributions to our U.S. Pension Plans during the first quarter of 2022.

In 2020, we announced the closing of our U.S.-based defined benefit pension plans to new non-union employees hired on or after January 1, 2020. We will introduce an all-401(k) plan retirement benefit structure for eligible employees with a higher company match of up to 8% across all U.S.-based operating companies in 2022. During calendar 2021, current eligible employees under the Portable Pension Account (“PPA”) pension formula were given a one-time option to continue to be eligible for pension compensation credits under the existing PPA formula and remain in the existing 401(k) plan with its match of up to 3.5%, or to cease receiving compensation credits under the PPA and move to the new 401(k) plan with the higher company match of up to 8%. Changes to the new 401(k) plan structure will become effective beginning January 1, 2022. While this new program will provide employees greater flexibility and reduce our long-term pension costs, it will not have a material impact on current or near-term financial results.
