Significant Accounting Policies | Note 1. Significant Accounting Policies Basis of Presentation The accompanying unaudited, interim condensed financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and, in management’s opinion, contain all adjustments (consisting of normal recurring items) necessary for a fair presentation, in all material respects, of the financial position and results of operations for the periods presented. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The preparation of condensed financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions. Such estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Our operating results are subject to seasonal trends; therefore, the results of operations for the interim period ended September 30, 2015 are not necessarily indicative of the results that may be expected for subsequent quarterly periods or the year ending December 31, 2015 . The condensed financial statements should be read in conjunction with the financial statements and related notes, which appear in our Annual Report on Form 10-K for the year ended December 31, 2014 . There have been no significant changes in the accounting principles and policies, long-term contracts or estimates inherent in the preparation of the condensed financial statements of Old Dominion Freight Line, Inc. as previously described in our Annual Report on Form 10-K for the year ended December 31, 2014 . Unless the context requires otherwise, references in these Notes to “Old Dominion,” the “Company,” “we,” “us” and “our” refer to Old Dominion Freight Line, Inc. Fair Values of Financial Instruments The carrying values of financial instruments in current assets and current liabilities approximate their fair value due to the short maturities of these instruments. The carrying value of our total long-term debt, including current maturities, and capital lease obligations was $185.4 million and $155.7 million at September 30, 2015 and December 31, 2014 , respectively. The estimated fair value of our total long-term debt and capital lease obligations was $192.4 million and $165.5 million at September 30, 2015 and December 31, 2014 , respectively. The fair value measurement of our senior notes was determined using a discounted cash flow analysis that factors in current market yields for comparable borrowing arrangements under our credit profile. Since this methodology is based upon market yields for comparable arrangements, the measurement is categorized as Level 2 under the three-level fair value hierarchy as established by the Financial Accounting Standards Board (the “FASB”). Earnings Per Share Earnings per share is computed using the weighted average number of common shares outstanding during the period. Stock Repurchase Program On November 10, 2014, we announced that our Board of Directors had approved a stock repurchase program authorizing us to repurchase up to an aggregate of $200.0 million of our outstanding common stock. We may repurchase shares from time-to-time in open market purchases or through privately negotiated transactions. The program expires on November 6, 2016. Shares of our common stock repurchased by us under the repurchase program are canceled at the time of repurchase and are authorized but unissued shares of our common stock. During the three and nine months ended September 30, 2015 , we repurchased 539,396 shares for $36.7 million and 1,126,984 shares for $79.1 million , respectively. As of September 30, 2015 , we had repurchased a total of 1,197,604 shares for $84.6 million , and $115.4 million remained authorized under the program. Supplemental Disclosure of Noncash Investing and Financing Activities Investing and financing activities that are not reported in the Statements of Cash Flows due to their non-cash nature are summarized below: Nine Months Ended September 30, (In thousands) 2015 2014 Acquisition of property and equipment by capital lease $ 3,552 $ — Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606). This ASU supersedes the previous revenue recognition requirements in Accounting Standards Codification ("ASC") Topic 605—Revenue Recognition and most industry-specific guidance throughout the ASC. The core principle within this ASU is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration expected to be received for those goods or services. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606), which deferred the effective date for ASU 2014-09 by one year to fiscal years beginning after December 15, 2017, while providing the option to early adopt for fiscal years beginning after December 15, 2016. Transition methods under ASU 2014-09 must be through either (i) retrospective application to each prior reporting periods presented, or (ii) retrospective application with a cumulative effect of this update at the date of initial application. We continue to assess the method of application and impact, if any, of the adoption of ASU 2014-09 on our financial position, results of operations and cash flows. |
