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 June 30, 2012 are not necessarily indicative of the results that may be expected for subsequent quarterly periods or the year ending December 31, 2012.

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, 2011.

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, 2011.

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.

Earnings Per Share

Earnings per common share is computed using the weighted average number of common shares outstanding during the period.

Fair Values of Financial Instruments

The carrying values of financial instruments, such as cash and cash equivalents, customer and other receivables and trade payables, approximate their fair value due to the short maturities of these instruments. The carrying value of our long-term debt was $267.9 million and $269.2 million at June 30, 2012 and December 31, 2011, respectively. The estimated fair value of our long-term debt was $280.5 million and $276.6 million at June 30, 2012 and December 31, 2011, respectively. The fair value measurement of our senior notes is based upon undiscounted cash flows at market interest rates for similar issuances of private debt. Since this methodology is based upon indicative market interest rates, the measurement is categorized as Level 2 under the three-level fair value hierarchy as established by the Financial Accounting Standards Board (the “FASB”). The fair value of our other long-term debt approximates carrying value.

Comprehensive Income

The Company has no components of other comprehensive income. Accordingly, net income equals comprehensive income for all periods presented in this report.
