Employee Benefit Plans

We sponsored a qualified defined-benefit pension plan and a post-retirement benefit plan (collectively, “the Pension Plans”). The plans are frozen and there have been no new entrants to the Pension Plans.

The following tables provide the components of the net periodic pension and other post-retirement benefit costs for the three and six months ended June 30, 2013 and 2012 (in millions):

We contributed $0.8 million and $1.3 million to the Pension Plans during the three and six months ended June 30, 2013, respectively, and $1.5 million during the three and six months ended June 30, 2012, respectively. We expect to contribute $2.1 million to the Pension Plans during the remainder of 2013.
