Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | COMMITMENTS AND CONTINGENCIES We have committed to property and equipment purchases of approximately $5.9 million at December 31, 2012. In November 2012, the IRS issued a Notice of Proposed Adjustment for tax years 2009 and 2010 related to an employment tax audit which focused on our driver per diem program. Under the program, eligible drivers may elect to receive a nontaxable reimbursement of certain expenses that are otherwise included in and contemplated as a portion of their compensation while away from home. The notice proposes that the nontaxable per diem payments are wages, resulting in additional FICA and FUTA taxes and federal income tax withholding obligations. If the IRS position is upheld, we estimate the additional expense for the 2009 and 2010 tax years to be approximately $16.5 million after considering the tax deductibility of the payments. We will submit a formal protest prior to the deadline of March 15, 2013. We believe our driver per diem program complies with applicable tax law, and we will vigorously defend against the IRS position. We have not accrued a liability because we believe we will ultimately prevail in this matter. We are involved in certain other claims and pending litigation arising in the ordinary course of business. Management believes the ultimate resolution of these matters will not materially affect our consolidated financial statements.
