We made contributions of $1.1 million and $5.2 million to the pension plans and other benefits plans, respectively, during the first quarter of 2012. In the first quarter of 2011, we made contributions of $1.3 million and $3.1 million to our pension and other benefits plans, respectively. The $3.1 million of contributions to the other benefits plans during the first quarter of 2011 reflected a $2.2 million reimbursement received relating to the Early Retiree Reinsurance Program, a one-time government program providing reimbursement for a portion of pre-65 health care benefit costs. The contributions in 2012 and 2011 also included benefit payments from our non-qualified pension plans and post-retirement benefit plans.

For 2012, there are no significant minimum funding requirements for our pension plans and planned voluntary funding of our pension plans in 2012 is not material.
