Although the Company is not required to make any contributions to its Company-sponsored pension plans in 2017, in the third quarter of 2017, the Company contributed $1,000, $650 net of tax, to the Company-sponsored pension plan that will significantly address the underfunded position of the Company-sponsored pension plan. The Company expects there will be a settlement charge in the fourth quarter of 2017 associated with the settlement of the Company-sponsored pension plan obligations for eligible participants’ pension balances that are distributed out of the plan via a transfer to other qualified retirement plan options or a lump sum payout, based on each participants’ election. The Company did not make any contributions to its Company-sponsored pension plans in the first two quarters of 2017 or 2016.

The Company contributed $121 and $117 to employee 401(k) retirement savings accounts in the first two quarters of 2017 and 2016, respectively.

The Company also contributes to various multi-employer pension plans based on obligations arising from most of its collective bargaining agreements. These plans provide retirement benefits to participants based on their service to contributing employers. The Company recognizes expense in connection with these plans as contributions are funded.

During the first quarter of 2017, the Company incurred a charge of $199, $126 net of tax, due to withdrawing from two multi-employer pension plans, which represents the Company’s best estimate of the withdrawal liability, absent demand letters from the multi-employer pension plans. Demand letters from the impacted multi-employer pension plans may be received in 2017, or later, and the ultimate withdrawal liability may change from the currently estimated amount. Any future charge will be recorded in the period in which the change is identified. Based on ERISA regulations, the liability will be paid out in installments, which vary by plan, over a period of up to 20 years. The net present value of the liability was determined using a risk free interest rate. The charge was recorded in the ‘Operating, general and administrative’ (“OG&A”) caption in the Consolidated Statements of Operations and the liability was recorded in the ‘Other long-term liabilities’ caption in the Consolidated Balance Sheets.

During the second quarter of 2016, the Company incurred a charge of $111, $71 net of tax, due to commitments arising from the restructuring of certain multi-employer pension plan obligations during the second quarter of 2016.
