Pension Plan Termination

On September 4, 2019, our Board of Directors approved the termination of the Trinity Industries, Inc. Consolidated Pension Plan (the "Pension Plan"), effective December 31, 2019. The Pension Plan was settled in the fourth quarter of 2020 which resulted in the Company no longer having any remaining funded pension plan obligations. Upon settlement, we recognized a pre-tax non-cash pension settlement charge in the fourth quarter of 2020 of $151.5 million, which was inclusive of all unamortized losses previously recorded in AOCL.

During the first quarter of 2021, as permitted by applicable regulations, we used $10.2 million of the Pension Plan surplus to fund obligations associated with the Company's profit sharing plans and $1.2 million to fund pension administrative expenses required to finalize the settlement of the Pension Plan. The remaining surplus of the Pension Plan of $12.2 million will be used to fund final pension administrative expenses. We expect that any remaining surplus would be used for other corporate purposes, subject to applicable taxes.
