401(k) plan description | During the second quarter of 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. During 2020, 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, 2021. 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. |
