New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	(13) Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update No. 2014 - 09, “Revenue from Contracts with Customers” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard, which is effective for the first quarter of 2018, will replace most existing revenue recognition guidance required by U.S. generally accepted accounting principles and will require additional disclosures. We have completed our evaluation of the requirements of the new guidance and have determined that our current policy in which we record revenue and related expenses on the date shipment of freight is completed, and in which we account for revenue of our Intermodal and Brokerage segments and revenue on freight transported by independent contractors within our Truckload and Dedicated segments on a gross basis, is also appropriate under the new guidance. As a result, our adoption of this standard effective January 1, 2018 is not expected to have a significant impact on our consolidated condensed balance sheets, statements of operations or statements of cash flows. We expect to complete our evaluation of the additional required disclosures in the second half of 2017. In February 2016, the FASB issued Accounting Standards Update No. 2016 - 02, “Leases” which requires organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The new guidance also requires additional disclosures related to leasing transactions. The standard is effective for the first quarter of 2019. The adoption of this standard is not expected to have a significant impact on our consolidated condensed balance sheets, statements of operations or statements of cash flows.
