In the third quarter of 2020, the Company recorded $6.6 million of settlement losses relating to retirees that elected to receive lump-sum distributions from the Company's defined benefit pension plans. This charge was the result of lump-sum payments which exceeded the threshold for settlement accounting under U.S. GAAP for the year.

Employer Contributions
 
The Company anticipates making required contributions of approximately $4.3 million to its foreign pension plans during 2020, of which $2.8 million has been contributed through September 30, 2020. Although not required by ERISA and the Internal Revenue Code, the Company may elect to make an additional voluntary contribution to its qualified domestic defined benefit pension plan in 2020. Additionally, we anticipate making cash payments of $6.0 million and $5.0 million due in 2020 and 2021, respectively, related to the previously disclosed settlement agreement with a multi-employer pension plan.
