Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | 1. General Basis of Presentation The accompanying unaudited interim Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. We believe such statements include all adjustments (consisting only of normal recurring adjustments) necessary for the fair presentation of our financial position, results of operations and cash flows at the dates and for the periods indicated. Pursuant to the requirements of the Securities and Exchange Commission (SEC) applicable to quarterly reports on Form 10-Q, the accompanying financial statements do not include all disclosures required by GAAP for annual financial statements. While we believe the disclosures presented are adequate to make the information not misleading, these unaudited interim Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2015. Operating results for the periods presented in this report are not necessarily indicative of the results that may be expected for the calendar year ending December 31, 2016, or any other interim period. Our business is somewhat seasonal with slightly higher freight volumes typically experienced during August through early November in our full-load freight transportation business. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, which supersedes virtually all existing revenue recognition guidance. The new standard requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. This update also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. We have the option of using either a full retrospective or a modified retrospective approach when adopting this new standard. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which deferred the effective date of ASU 2014-09 one year to interim and annual periods beginning after December 15, 2017. Early adoption is permitted after the original effective date of December 15, 2016. We are currently evaluating the alternative transition methods and the potential effects of the adoption of this update on our financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities, which amends certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The amendments are to be applied by means of a cumulative-effect adjustment to the balance sheet and are effective for interim and annual periods beginning after December 15, 2017. With certain exceptions, early adoption is not permitted. The adoption of the new guidance is not expected to have a material impact on our financial statements. In February 2016, the FASB issued ASU 2016-02, Leases, which requires lessees to recognize a right-of-use asset and a lease liability for most leases in the balance sheet as well as other qualitative and quantitative disclosures. ASU 2016-02 is to be applied using a modified retrospective method and is effective for interim and annual periods beginning after December 15, 2018, but early adoption is permitted. We are currently evaluating the potential effects of the adoption of this update on our financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation – Stock Compensation: Improvements to Employee Share-Based Payment Accounting, which amends and simplifies certain aspects of accounting for share-based payment award transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The amendments are effective for interim and annual periods beginning after December 15, 2016, but early adoption is permitted. The application methods to be used in adoption vary with each component of the standard. We are currently evaluating the potential effects of the adoption of this update on our financial statements. Accounting Pronouncement Adopted in 201 6 In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs, which amended the current presentation of debt issuance costs in the financial statements. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts, instead of as an asset. The amendments are to be applied retrospectively and were effective for interim and annual periods beginning after December 15, 2015. We retroactively adopted ASU 2015-03 at March 31, 2016, and have reclassified all prior periods to be consistent with the amendments outlined in the ASU. The impact of the prior period reclassification was a $1.4 million reduction of current assets, a $5.6 million reduction of other assets, and a $7.0 million reduction of long-term debt at December 31, 2015. |
