(1)Included in contract drilling and general and administrative expense in our Condensed Consolidated Statements of Operations. (2)Included in other, net, in our condensed consolidated statements of operations. During the nine months ended September 30, 2020, we contributed $11.0 million to our pension and other post-retirement benefit plans. The U. S. Cares Act provides relief for pension payments allowing for deferral of approximately $21.0 million of anticipated payments to January 1, 2021. These amounts represent the minimum contributions we are required to make under relevant statutes. We do not expect to make contributions in excess of the minimum required amounts.
