Additionally, the amortization of defined-benefit pension and post-retirement benefits included $3 million, net of tax, due to the disposition of pension plans in connection with the divestiture of Hüppe.

In addition to the above amounts, we reclassified $23 million of currency translation losses from accumulated other comprehensive income (loss) to the consolidated statements of operations in conjunction with the divestiture of Hüppe in the second quarter of 2021. Also, we reclassified $9 million of deferred currency translation losses from accumulated other comprehensive income (loss) to the consolidated statements of operations in conjunction with the liquidation of certain UK dormant entities upon receiving final regulatory approval in 2020. Additionally, we reclassified $14 million of deferred currency translation losses from accumulated other comprehensive income (loss) to the consolidated statements of operations in conjunction with the disposition of UKWG in the third quarter of 2019.
