Nonunion Defined Benefit Pension Plan The Company’s nonunion defined benefit pension plan covers substantially all noncontractual employees hired before January 1, 2006. In June 2013, the Company amended the nonunion defined benefit pension plan to freeze the participants’ final average compensation and years of credited service as of July 1, 2013. The plan amendment did not impact the vested benefits of retirees or former employees whose benefits have not yet been paid from the plan. Effective July 1, 2013, participants of the nonunion defined benefit pension plan who were active employees of the Company became eligible for the discretionary defined contribution feature of the Company’s nonunion 401(k) and defined contribution plan in which all eligible noncontractual employees hired subsequent to December 31, 2005 also participate. In November 2017, an amendment was executed to terminate the nonunion defined benefit pension plan with a termination date of December 31, 2017. The plan has filed for a determination letter from the IRS regarding the qualification of the plan termination. Following receipt of a favorable determination letter, benefit election forms will be provided to plan participants and they will have an election window in which they can choose any form of payment allowed by the plan for immediate commencement of payment or defer payment until a later date. Until a favorable determination letter is received and the benefit election forms are distributed to participants, the methodologies for establishing plan assumptions will continue to be consistent with those used prior to the amendment to terminate the plan. Pension settlement charges related to the plan termination, including settlements for lump sum benefit distributions and the cost to purchase an annuity contract to settle the pension obligation related to benefits for which participants elect to defer payment until a later date, may occur in 2018. However, the timing of recognizing these settlements in the consolidated financial statements is highly dependent on when and if the plan receives the favorable determination letter from the IRS. The Company recognized pension settlement expense as a component of net periodic benefit cost of the nonunion defined benefit pension plan for the three months ended March 31, 2018 of $0.7 million (pre-tax), or $0.5 million (after-tax), related to $4.8 million of lump-sum benefit distributions from the plan. For the three months ended March 31, 2017, pension settlement expense of $2.0 million (pre-tax), or $1.2 million (after-tax), was recognized related to $4.8 million of lump-sum distributions from the plan and a $7.6 million nonparticipating annuity contract purchased from an insurance company to settle the pension obligation related to the vested benefits of approximately 50 plan participants and beneficiaries receiving monthly benefit payments at the time of the contract purchase. Upon recognition of pension settlement expense, a corresponding reduction in the unrecognized net actuarial loss of the plan is recorded. The remaining pre-tax unrecognized net actuarial loss will continue to be amortized over the average remaining future years of service of the active plan participants. The Company will incur additional quarterly settlement expense related to lump-sum distributions from the nonunion defined benefit pension plan during the remainder of 2018. The following table discloses the changes in benefit obligations and plan assets of the nonunion defined benefit pension plan for the three months ended March 31, 2018:

Based upon currently available actuarial information, and except for the impact of funding for plan termination, the Company does not expect to have cash outlays for required minimum contributions to its nonunion defined benefit pension plan in 2018. The plan’s preliminary adjusted funding target attainment percentage (“AFTAP”) is 112.97% as of the January 1, 2018 valuation date. The AFTAP is determined by measurements prescribed by the Internal Revenue Code, which differ from the funding measurements for financial statement reporting purposes. 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. ABF Freight’s contributions generally are based on the time worked by its contractual employees, in accordance with the 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 25 multiemployer pension plans to which ABF Freight contributes vary greatly in size and in funded status. Contribution obligations to these plans are generally specified in the ABF NMFA, which remained in effect through March 31, 2018 and was extended to allow for the ratification process of the new agreement to take place. The funding obligations to the 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. Provisions of the Reform Act include, among others, providing qualifying plans the ability to self-correct funding issues, subject to various requirements and restrictions, including applying to the U.S. Department of the Treasury for the reduction of certain accrued benefits. Through the term of its current collective bargaining agreement, ABF Freight’s contribution obligations generally will be satisfied by making the specified contributions when due. However, the Company cannot determine with any certainty the contributions that will be required under future collective bargaining agreements for ABF Freight’s contractual employees. 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. 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”). ABF Freight received an Actuarial Certification of Plan Status for the Central States Pension Plan dated March 30, 2018, in which the plan’s actuary certified that, as of January 1, 2018, the plan is in critical and declining status, as defined by the Reform Act. 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%. 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 2017 Annual Report on Form 10-K.
