[1] In December 2020, we eliminated our qualified defined benefit pension plan (Plan Termination), as discussed in Note 11, Retirement and Benefit Plans. Prior to the Plan Termination, "Accumulated other comprehensive loss" on our Consolidated Balance Sheet included the stranded tax effects of our conversion from a limited liability company to a corporation in 2013 and the adoption of the Tax Cuts and Jobs Act in 2017. Upon Plan Termination, these stranded tax effects of $38.8 million were required to be released into income tax expense under GAAP.
