EMPLOYEE BENEFIT PLANS

 

U.S. Defined Benefit Pension Plan

 

We have a defined benefit pension plan (pension plan) that covers certain U.S. citizen employees and other employees who are permanent residents of the United States. The pension plan was frozen during 2010. We have not made contributions to the pension plan since 2019. Actuarial valuations are performed annually and an assessment of the future pension obligations and market value of the assets will determine if contributions are made in the future.

 

Supplemental Executive Retirement Plan

 

We also support a non-contributory and non-qualified defined benefit supplemental executive retirement plan (supplemental plan) which was closed to new participants during 2010. We contributed $0.8 million during each of the six months ended June 30, 2021 and 2020, respectively. We expect to contribute $0.8 million to the supplemental plan during the remainder of 2021. Our obligations under the supplemental plan were $22.8 million for both  June 30, 2021 and  December 31, 2020, respectively, and are included in “accrued expenses” and “other liabilities” in the condensed consolidated balance sheet.
