Pension and other postretirement liabilities for continuing operations of $91.4 million and $91.2 million are included in "Other noncurrent liabilities" in the consolidated balance sheets at June 30, 2013 and December 31, 2012, respectively. We contributed $2.3 million to our pension plans for continuing operations in 2012, and our required contributions are expected to be approximately $0.2 million in 2013. We also intend to make an additional discretionary contribution of $5.0 million to our underfunded pension plan in 2013. We fund our other post-retirement benefits (life insurance and health benefits) on a claims-made basis, which were $0.3 million for the year ended December 31, 2012.
