The Company anticipates making no additional cash contributions to its pension plans in the remainder of 2018.

In the first quarter of 2018, the Company adopted ASU 2017-07, which requires that all net periodic pension and postretirement benefit costs, with the exception of service costs, be included as a component of non-operating income on the Company's Condensed Consolidated Statements of Operations and Comprehensive (Loss) Income. Prior to the adoption of ASU 2017-07, the Company reported net periodic pension and postretirement benefit costs as a component of sales, general and administrative expense. As a result of the adoption of ASU No. 2017-07, the Company included the interest cost component of net periodic pension and postretirement benefit costs of $1,225 in interest expense and the expected return on assets component net periodic pension and postretirement benefit costs of $1,971 in other expense (income), net on the Condensed Consolidated Statements of Operations and Comprehensive (Loss) Income in the three months ended September 30, 2018 (Successor) and included the interest cost component of net periodic pension and postretirement benefit costs of $3,675 in interest expense and the expected return on assets component net periodic pension and postretirement benefit costs of $5,913 in other expense (income), net on the Condensed Consolidated Statements of Operations and Comprehensive (Loss) Income in the nine months ended September 30, 2018 (Successor). Prior year amounts have been reclassified to conform to the current year presentation in the Condensed Consolidated Financial Statements (see Note 3 - New Accounting Standards).

The Company was party to a multi-employer pension plan. In connection with the April 2015 restructuring plan, which is now complete, the Company stated its intention to withdraw from the multi-employer pension plan. At September 30, 2018 (Successor), the total estimated liability to withdraw from the plan is $3,307. The current liability associated with the Company's withdrawal from the multi-employer pension plan of $240 is included in accrued and other current liabilities in the Condensed Consolidated Balance Sheet and the long-term liability of $3,067 is included in other noncurrent liabilities in the Condensed Consolidated Balance Sheet.
