(1)Included in Other, net, in our Condensed Consolidated Statements of Operations. In March 2021, the American Rescue Plan Act of 2021 ("ARPA-21") was passed. ARPA-21 provides funding relief for U.S. qualified pension plans which lower pension contribution requirements over the next few years. During the nine months ended September 30, 2022 (Successor), we contributed or directly paid $3.3 million to our pension and other post-retirement benefit plans. We currently expect to contribute or directly pay $1.7 million to our pension and other post-retirement benefits plans for the remainder of 2022. These amounts represent the minimum contributions we are required to make under relevant statutes. We do not expect to make contributions in excess of the minimum required amounts.
