​ ​ Multiemployer Plans ​ ABF Freight System, Inc. and certain other subsidiaries reported in the Company’s Asset-Based operating segment (“ABF Freight”) contribute to multiemployer pension and health and welfare plans, which have been established pursuant to the Taft-Hartley Act, to provide benefits for its contractual employees. The 25 multiemployer pension plans to which ABF Freight contributes vary greatly in size and in funded status. Contributions to these plans are based generally on the time worked by ABF Freight’s contractual employees at rates specified in the 2018 ABF NMFA and other related supplemental agreements. ABF Freight recognizes as expense the contractually required contributions for each period and recognizes as a liability any contributions due and unpaid. The funding obligations to the multiemployer pension plans are intended to satisfy the requirements imposed by the Pension Protection Act of 2006, which was permanently extended by the Multiemployer Pension Reform Act (the “Reform Act”) included in the Consolidated and Further Continuing Appropriations Act of 2015. ​ Approximately one half of ABF Freight’s total contributions to multiemployer pension plans are made to the Central States, Southeast and Southwest Areas Pension Plan (the “Central States Pension Plan”). As set forth in the 2020 Annual Funding Notice for the Central States Pension Plan, the funded percentage of the plan was 19.5% as of January 1, 2020. In the Notice of Critical and Declining Status for the Central States Pension Plan dated March 31, 2021, the plan’s actuary certified that the plan is in critical and declining status, as defined by the Reform Act, for the plan year beginning January 1, 2021. Critical and declining status is applicable to critical status plans that are projected to become insolvent anytime within the next 14 plan years, or if the plan is projected to become insolvent within the next 19 plan years and either the plan’s ratio of inactive participants to active participants exceeds two to one or the plan’s funded percentage is less than 80%. ​ On March 11, 2021, H.R.1319, the American Rescue Plan Act of 2021 (the “American Rescue Plan Act”) was signed into law. The American Rescue Plan Act includes the Butch Lewis Emergency Pension Plan Relief Act of 2021 (the “Pension Relief Act”). The Pension Relief Act includes provisions to improve funding for multiemployer pension plans, including financial assistance provided through the Pension Benefit Guarantee Corporation (the “PBGC”) to qualifying underfunded plans to secure pension benefits for plan participants. Without the funding to be provided by the Pension Relief Act, many of the multiemployer pension funds to which ABF Freight contributes, including the Central States Pension Plan, could become insolvent in the near future; however, ABF Freight would continue to be obligated to make contributions to those funds under the terms of the 2018 ABF NMFA. ​ Through the term of the 2018 ABF NMFA, which extends through June 30, 2023, ABF Freight’s multiemployer pension contribution obligations generally will be satisfied by making the specified contributions when due. Future contribution rates will be determined through the negotiation process for contract periods following the term of the current collective bargaining agreement. While the Company cannot determine with any certainty the contributions that will be required under future collective bargaining agreements for ABF Freight’s contractual employees, management believes future contribution rates to multiemployer pension plans may be less likely to increase as a result of the provisions of the Pension Relief Act. If ABF Freight was to completely withdraw from certain multiemployer pension plans, under current law, ABF Freight would have material liabilities for its share of the unfunded vested liabilities of each such plan. More information will become available as the PBGC develops and issues regulations to implement the financial assistance program provided by the American Rescue Plan Act. ​ The multiemployer plan administrators have provided to the Company no other significant changes in information related to multiemployer plans from the information disclosed in the Company’s 2020 Annual Report on Form 10-K.
