Pension Plans

We sponsored a qualified defined-benefit pension plan and a post-retirement benefit plan (collectively, “the Pension Plans”) consisting of a Core-Mark pension plan, which was frozen on September 30, 1986 and three plans we inherited from Fleming, our former parent company. The Fleming plans were frozen on, or prior to, August 20, 1998. There have been no new entrants to the Pension Plans after those benefit plans were frozen.

Our defined-benefit pension plan is subject to the Employee Retirement Income Security Act of 1974 (“ERISA”). Under ERISA, the Pension Benefit Guaranty Corporation (“PBGC”) has the authority to terminate an underfunded pension plan under limited circumstances. In the event our pension plan is terminated for any reason while it is underfunded, we will incur a liability to the PBGC that may be equal to the entire amount of the underfunding. Our post-retirement benefit plan is not subject to ERISA. As a result, the post-retirement benefit plan is not required to be pre-funded, and, accordingly, has no plan assets.

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, 2012 and 2011 (in millions):

We contributed $1.5 million to the Pension Plans during the three and six months ended June 30, 2012, and $0.4 million during the three and six months ended June 30, 2011. We expect to contribute a total of approximately $3.2 million to the Pension Plans during 2012.
