Adjusted Diluted Earnings per Share: We expect 2013 adjusted diluted earnings per share to be in the range of $1.86 to $1.91. This assumes a full year effective tax rate of approximately 38 percent. Adjusted diluted earnings per share excludes loss on extinguishment of debt, if any, negotiation and withdrawal costs - Central States Pension Fund, restructuring charges and (gain) loss on disposition of assets and impairments, net, if any.

•	Revenue: We expect an increase in revenue for 2013 of 2.0 to 2.5 percent comprised of the following:

•

Property and Equipment: In 2013, we anticipate receiving $860 million of property and equipment. Purchases of property and equipment as reflected on our consolidated statement of cash flows for 2013 are expected to be $880 million and represent amounts to be paid during 2013 for such expenditures. The $20 million difference between property and equipment received and purchases of property and equipment represents property and equipment received during 2012, but paid for in 2013.

•	Margins: We expect EBITDA margins for 2013 to be approximately 29 percent.

•	Taxes: We expect our provision for income taxes in 2013 to be 38 percent and to approximate our cash taxes.
