Defined benefit plan, termination process description In February 2021, we received a determination letter from the Internal Revenue Service that allows us to proceed with the termination process for the Plan. In connection with the termination, the Plan has offered a window extending from March 29, 2021 through May 7, 2021 to certain eligible participants to elect lump sum payments. The distribution date is June 1, 2021. The completion of the Plan termination process, including the final purchase of annuities, is expected to occur in the second half of 2021.
