Employee Benefit Plans

We have defined benefit pension plans for our U.K.-based union employees and certain Canadian-based employees (the “U.K. Plan” and the “Canadian Plan,” respectively). Retirement benefits under the U.K. Plan are based on an employee’s average compensation over the two years preceding retirement. Retirement benefits under the Canadian Plan are generally based on the number of years of credited service. Our policy is to fund the minimum contribution permissible by the applicable regulatory authorities.

The following table sets forth the combined amount of net periodic benefit cost recognized for the three and six months ended June 30, 2014 and 2013:

We have a 401(k) plan for U.S.-based employees. We contribute 37.5 cents on the dollar for the first 6% of participant contributions for a match of up to 2.25% of eligible compensation. In connection with the WMS acquisition, we assumed existing 401(k) plans of WMS. These plans cover union and non-union full-time employees of WMS and provide for contributions of up to 4.5% of covered non-union employees’ eligible compensation and a maximum fixed annual amount for covered union employees' eligible compensation as defined in the plans.
