ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION

     On April 22, 2005, we reported our financial results for our fiscal quarter
ended March 31, 2005. This press release is furnished as Exhibit 99 hereto. In
the press release, we provide net earnings and the related per share amount
excluding the effects of tax-free life insurance proceeds and operating revenue
excluding fuel surcharge revenue. These measures are not in accordance with, or
an alternative for, generally accepted accounting principles and may be
different from operational income, operational revenue and per share measures
used by other companies. We believe that the presentation of these measures
provide useful information to investors regarding business trends relating to
our financial condition and results of ongoing operations.
