EMPLOYEE BENEFIT PLANS

The Company sponsors several pension and post-employment benefit plans in the U.S. and internationally, of which, approximately half of such plans are frozen to new participants.

We recognized net actuarial gains in the amount of $8.5 million during the year ended December 31, 2021 and net actuarial losses of $5.5 million and $2.5 million during the years ended December 31, 2020 and 2019, respectively. The actuarial gains and losses are reflected in our consolidated statements of comprehensive income (loss). The unfunded liability of the plans as of December 31, 2021 and 2020 was approximately $13.9 million and $24.9 million, respectively, and is included in other long-term liabilities within our consolidated balance sheets. The net periodic benefit expense was $2.5 million, $3.2 million, and $2.0 million for the years ended December 31, 2021, 2020, and 2019, respectively.
