Section 2 – Financial Information

Item 2.02.  Results of Operations and Financial Condition.

On October 16, 2012, the company issued a press release announcing financial results for the quarter ended September 30, 2012.  Attached hereto as Exhibit 99.1 is a copy of the company’s press release dated October 16, 2012 announcing the company’s financial results for this period.

The press release also includes a discussion of operating revenue, net of fuel surcharge revenue; operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharge revenue; and logistics revenue, net of intermodal fuel surcharge revenue.  The company provided these additional disclosures because management believes removing these sources of revenue provides a more consistent basis for comparing results of operations from period to period.  These financial measures in the press release have not been determined in accordance with generally accepted accounting principles (“GAAP”).  Pursuant to Regulation G, the company has included a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures.  For the discussion of operating revenue, net of fuel surcharge revenue; operating expenses as a percentage of operating revenue, with both amounts net of fuel surcharge revenue; and logistics revenue, net of intermodal fuel surcharge revenue, the most directly comparable GAAP financial measures are operating revenue, operating expenses divided by operating revenue, and logistics revenue, respectively, which are reconciled in the attached Exhibit 99.1.

The information contained in this report and the exhibit hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.
