_______________ (1)The 2021 changes in the projected benefit obligation and plan assets reflect the effect of the Hudson Plan merger. The Hudson Plan accrued pension liability as of December 31, 2020 is not included in the table above. At December 31, 2020, the projected benefit obligation of the Hudson Plan was $2.9 while the fair value of plan assets was $2.0. Consequently, at December 31, 2020, a liability of $1.0, was included in accrued pension liabilities on the consolidated balance sheets for the underfunded status of the Hudson Plan. Pension expense relative to the Hudson Plan in 2020 was not significant.
