Business Combination Disclosure [Text Block] | 12. Equity Investment We own a 45% equity interest in MWL, a third-party provider of logistics services to the transportation industry. A non-related party owns the other 55% equity interest in MWL. Pursuant to the guidance in the Variable Interest Entities (VIE) Subsections of FASB ASC 810, Consolidation , we included the accounts of MWL in our consolidated financial statements from April 1, 2004 to March 27, 2013, as we were deemed to be the entity’s primary beneficiary. On March 28, 2013, the other member of MWL made a capital contribution to MWL which triggered a VIE reconsideration event, and it was no longer required to be consolidated as of that date. Accordingly, we deconsolidated MWL and have accounted for our ownership interest in MWL under the equity method of accounting, effective as of March 28, 2013. Under the deconsolidation accounting guidelines, the investor’s opening investment is recorded at fair value as of the date of deconsolidation. The difference between this initial fair value of the investment and the net carrying value is recognized as a gain or loss in earnings. We completed a valuation analysis and determined that the net carrying value of our equity interest in MWL as of March 28, 2013 of $2.6 million was equal to its fair value and, as such, no gain or loss was recognized upon deconsolidation of MWL. In determining the fair value, we utilized a combination of the income and market approaches, and equally weighed the business enterprise value of MWL provided by each approach. The income approach included the following inputs and assumptions: (a) an expectation regarding the growth of MWL’s revenue at a compounded average growth rate; (b) a perpetual long-term growth rate; and (c) a discount rate that was based on MWL’s estimated weighted average cost of capital. The market approach included a range of multiples of selected comparable companies applied to MWL’s financial metrics for the trailing twelve months in order to obtain an indication of MWL’s business enterprise value on a minority, marketable basis. Due to the significance of inputs used in determining the fair value of our equity interest in MWL that are unobservable, the investment is classified within Level 3 of the fair value hierarchy that prioritizes from Level 1 to Level 3 the inputs to fair value valuation techniques under the provisions of the accounting guidance for fair value measurements. Fair value measurements using Level 1 inputs provide the most reliable measure of fair value, while Level 3 inputs generally require significant management judgment. Following the deconsolidation, as an equity method investment, MWL is considered a related party. We received $5.0 million, $8.5 million and $8.2 million of our revenue for loads transported by our tractors and arranged by MWL in 2015, 2014 and 2013, respectively. Prior to deconsolidation effective March 28, 2013, these inter-segment revenues were eliminated in consolidation. Inter-segment revenue eliminated in consolidation was $2.1 million in 2013 . As of December 31, 2015, we also had a trade receivable in the amount of $204,000 from MWL and an accrued liability of $4.3 million to MWL for the excess of payments by MWL’s customers into our lockbox account over the amounts drawn on the account by MWL.
