The Company has no minimum funding requirements for its domestic pension plans in 2021. As a result of the Merger, as well as due to tax planning considerations related to probable changes in U.S. tax law, the Company anticipates reducing its voluntary contributions to its domestic pension plans during 2021 as compared to the amount disclosed at December 31, 2020. During 2021, the Company expects to contribute between $8,000 and $28,000 to its domestic and international pension plans.
