The Company is not required and does not expect to make any contributions to the Company-sponsored defined benefit pension plans in 2014.

The Company contributed $98 and $80 to employee 401(k) retirement savings accounts in the first two quarters of 2014 and 2013, 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 2014, the Company incurred a charge of $56 (after-tax) due to commitments and withdrawal liabilities arising from the restructuring of certain multi-employer pension plan obligations.
