<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:120%;padding-top:12px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Accounting Standards Updates Not Yet Effective:</font><font style="font-family:inherit;font-size:10pt;"> On May 28, 2014, the FASB issued ASU 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 ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The FASB has also issued additional guidance related to revenue recognition matters in subsequent ASUs, including a one-year deferral of the effective date of the new revenue standard. As a result of the deferral, the new standard is effective for us beginning January 1, 2018. Prior to adopting, we recognize revenue and related direct costs when the shipment is delivered. Effective January 1, 2018, the new standard requires us to recognize revenue and related direct costs over time as the shipment is being delivered. The standard permits the use of either the full retrospective or modified retrospective (cumulative effect) transition method. We will adopt the standard using the modified retrospective transition method. Based on our evaluation, the adoption of this standard will not have a material effect on our consolidated financial statements, although additional disclosures will be required.</font></div><div style="line-height:120%;padding-top:12px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In February 2016, the FASB issued ASU No. 2016-02, “Leases,” to increase transparency and comparability by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The provisions of this update are effective for fiscal years beginning after December 15, 2018. We are evaluating the effect that ASU No. 2016-02 will have on our consolidated financial position, results of operations and cash flows.</font></div><div style="line-height:120%;padding-top:12px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The provisions of this update are effective for fiscal years beginning after December 15, 2017. Based on our evaluation, the adoption of this standard will not have a material effect on our consolidated statement of cash flows.</font></div><div style="line-height:120%;padding-top:12px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” which requires an entity to include in its cash and cash-equivalent balances in the statement of cash flows those amounts that are deemed to be restricted cash and restricted cash equivalents. The provisions of this update are effective for fiscal years beginning after December 15, 2017, and retrospective adoption is required. The adoption of this standard will impact the consolidated statements of cash flows by increasing beginning and ending cash to include the restricted balance of our like-kind exchange account and remove from operating activities the change in such balance.</font></div><div style="line-height:120%;padding-top:12px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In May 2017, the FASB issued ASU No. 2017-09, “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting,” which provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The provisions of this update are effective for fiscal years beginning after December 15, 2017, and would be applied prospectively to an award modified on or after the adoption date, if any such modification were to occur.</font></div><div style="line-height:120%;padding-top:8px;text-align:justify;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities,” with the objective of improving the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. The provisions of this update are effective for fiscal years beginning after December 15, 2018. We are evaluating the effect that ASU No. 2017-12 will have on our financial position, results of operations and cash flows.</font></div></div> | |

(the “Company”) is a truckload transportation and logistics company operating under the jurisdiction of the U.S. Department of Transportation, similar governmental transportation agencies in the foreign countries in which we operate and various U.S. state regulatory authorities. For the years ended December 31, 2017, 2016 and 2015, our ten largest customers comprised </font><font style="font-family:inherit;font-size:10pt;">43%</font><font style="font-family:inherit;font-size:10pt;">, </font><font style="font-family:inherit;font-size:10pt;">43%</font><font style="font-family:inherit;font-size:10pt;"> and </font><font style="font-family:inherit;font-size:10pt;">45%</font><font style="font-family:inherit;font-size:10pt;">, respectively, of our revenues. No single customer generated more than 8% of the Company’s total revenues in 2017, 2016, and 2015.</font></div></div> | |

An impairment loss would be recognized if the carrying amount of the long-lived asset is not recoverable and the carrying amount exceeds its fair value. For long-lived assets classified as held and used, the carrying amount is not recoverable when the carrying value of the long-lived asset exceeds the sum of the future net cash flows. We do not separately identify assets by operating segment because tractors and trailers are routinely transferred from one operating fleet to another. As a result, none of our long-lived assets have identifiable cash flows from use that are largely independent of the cash flows of other assets and liabilities. Thus, the asset group used to assess impairment would include all of our assets.</font></div></div> | |

The most significant estimates that affect our financial statements include the useful lives and salvage values of property and equipment, accrued liabilities for insurance and claims, estimates for income taxes and the allowance for doubtful accounts. Actual results could differ from those estimates.</font></div></div> |
