Cost-method Investments, Description [Text Block]	5. INVESTMENT IN TRANSPLACE From July 2001 through December 2009, we owned approximately 12.4% of Transplace, Inc. ("Transplace"), a global transportation logistics service. In the formation transaction for Transplace, we contributed our logistics customer list, logistics business software and software licenses, certain intellectual property, intangible assets, and $5.0 million in cash, in exchange for our ownership. We accounted for this investment, which totaled approximately $10.7 million, using the cost method of accounting, and it was historically included in other assets in the consolidated balance sheet. Also, during the first quarter of 2005, we loaned Transplace approximately $2.6 million, which along with the related accrued interest was historically included in other assets in the consolidated balance sheet. Based on an offer to purchase our 12.4% equity ownership and related note receivable in Transplace that was accepted by a majority of the stockholders, we determined that the value of our equity investment had become completely impaired in the third quarter of 2009, and the value of the note receivable had become impaired by approximately $0.9 million. As a result, we recorded a non-cash impairment charge of $11.6 million during the third quarter of 2009. The transaction closed in December 2009, whereby the proceeds of $1.9 million provided for a recovery of $0.1 million of the previously impaired amount in the fourth quarter of 2009 and thus an $11.5 million non-cash loss on the sale of our investment and related note receivable. There was no tax benefit recorded in connection with the loss on the sale of the investment, given a full valuation allowance was established for the related capital loss. Under our Credit Facility, the non-cash loss was added back in the computation of our fixed charge coverage ratio. We provided transportation services to Transplace which generated gross revenues of approximately $18.8 million in 2009 and trade accounts receivable of approximately $4.7 million at December 31, 2009.

- Definition

The entire disclosure for investments accounted for under the cost-method. The carrying amount of such investments may be adjusted, for example, distributions in excess of cost (return of capital) or for other-than-temporary impairments. The cost method and lower-of-cost or market, an adaptation of the cost method, is generally followed for most investments in noncontrolled corporations, in some corporate joint ventures, and to a lesser extent in unconsolidated subsidiaries in which the entity does not have the ability to exercise significant influence.
