For 2021, 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 voluntary contributions to our U.S. Pension Plans of $1.0 billion during the first quarter of 2020.

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 will be 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 pension plan and move to the new 401(k) plan with the higher match of up to 8%. Changes to the new 401(k) plan structure 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.
