We announced to plan participants that we will freeze accrual of all benefits on our qualified defined benefit pension plan (Pension Plan) effective August 31, 2020, as well as our intention to terminate the Pension Plan.

During the six months ended June 30, 2020, we contributed $1.1 million in cash to the pension plans. For the remainder of 2020, we expect to make approximately $13 million in cash contributions to the pension plans, which includes the repurchase of two BMD locations leased from the Pension Plan. For information related to the contribution of properties to our qualified defined benefit pension plan, see Note 12, Retirement and Benefit Plans, of the Notes to Consolidated Financial Statements in "Item 8. Financial Statements and Supplementary Data" in our 2019 Form 10-K.
