Employee Benefit Plans

The Company maintains a non-contributory defined benefit pension plan that covers substantially all U.S. employees who were employed at December 31, 2011. After that date, no further benefits are being accrued in this plan. For the frozen pension plan, benefits are based primarily on years of service and, for certain employees, levels of compensation.

The Company also maintains supplemental non-qualified plans for certain officers and other key employees, and an Employee Savings and Stock Option Plan (“ESSOP”).

The Company additionally has a postretirement healthcare benefit plan that provides medical benefits for certain U.S. retirees and eligible dependents hired prior to November 1, 2004. Employees are eligible to receive postretirement healthcare benefits upon meeting certain age and service requirements. No employees hired after October 31, 2004 are eligible to receive these benefits. This plan requires employee contributions to offset benefit costs.

The Company disclosed in its financial statements for the year ended December 31, 2014 that it was not required to make a minimum contribution to the defined benefit pension plan for the 2015 calendar year. The Company continues to believe no additional contributions will be required during 2015. During the third quarter of 2014, the Company began moving assets within its defined pension plan from its equity and fixed income policy towards a strategy more focused on fixed income. The intent was to more closely align assets with the corresponding pension liability and reduce exposure in equities.

The Company also disclosed in its financial statements for the year ended December 31, 2014 that it estimated it would pay $0.4 million in other postretirement benefits in 2015 based on actuarial estimates. As of June 30, 2015, $0.1 million of such benefits have been paid. The Company continues to believe that its estimated payments for the full year are reasonable. However, such estimates contain inherent uncertainties because cash payments can vary significantly depending on the timing of postretirement medical claims and the collection of the retirees’ portion of certain costs. Note that the amount of benefits paid in calendar year 2015 will not impact the expense for postretirement benefits for 2015.
