As of June 30, 2014 we have frozen the pension benefits provided to our hourly pension plan participants. This means that: (i) hourly pension plan participants will not earn any additional years of Benefit Service under the plan after June 30, 2014 for purposes of accruing an additional plan benefit; and (ii) no pay increases/decreases that hourly pension plan participants earn after June 30, 2014 will be taken into account in determining their plan benefit.

We have a defined contribution retirement plan that covers substantially all U.S. employees. The expense for this plan was $0.2 million and $0.5 million for the three months ended June 30, 2014 and 2013, respectively and $0.4 million and $1.3 million for the six months ended June 30, 2014 and 2013, respectively. All contributions were funded from the proceeds obtained from the reversion of our former salaried pension plan; these funds will be exhausted during 2014.
