The minimum annual contribution for 2013 will be zero so we will not be required to fund our qualified pension plan during 2013. However, it is possible that we may fund the qualified and nonqualified pension plans in 2013 for a combined total of $60.0 million to $110.0 million. During the three and six months ended June 30, 2013, we contributed $27.0 million and $54.0 million to these plans, respectively.   </div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for pension and other postretirement benefits.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 715 -URI http://asc.fasb.org/topic&trid=2235017 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Implementation Guide (Q and A) -Number FAS88 -Paragraph 63 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
