During 2020, we made lump-sum pension benefit distributions exceeding the settlement accounting threshold. Accordingly, we recorded a non-cash pension settlement charge of $30.4 million and $27.7 million in non-operating expenses on our consolidated statements of income for the year ended December 31, 2021 and 2020, respectively. This settlement charge represented the immediate recognition into expense of a portion of the unrecognized loss within accumulated other comprehensive loss in proportion to the share of the projected benefit obligation that was settled by the lump-sum pension benefit distributions and purchases of the nonparticipating annuity contracts.
