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 March 31, 2019 are not necessarily indicative of the results that may be expected for the subsequent quarterly periods or the year ending December 31, 2019.

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, 2018. 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, 2018, other than those disclosed in this Form 10-Q.

Certain amounts in prior years have been reclassified to conform prior years’ financial statements to the current presentation.

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.

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 was $45.0 million at each of March 31, 2019 and December 31, 2018. The estimated fair value of our total long-term debt was $46.0 million and $45.6 million at March 31, 2019 and December 31, 2018, 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”).

On May 17, 2018, we announced that our Board of Directors had approved a two-year stock repurchase program authorizing us to repurchase up to an aggregate of $250.0 million of our outstanding common stock (the “Repurchase Program”). Under the Repurchase Program, which became effective upon the expiration of our prior stock repurchase program in June 2018, we may repurchase shares from time to time in open market purchases or through privately negotiated transactions. Shares of our common stock repurchased under the Repurchase Program are canceled at the time of repurchase and are classified as authorized but unissued shares of our common stock.

During the three months ended March 31, 2019, we repurchased 221,809 shares of our common stock for $30.6 million. As of March 31, 2019, we had $101.1 million remaining authorized under the Repurchase Program.

In February 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-02, “Leases” (Topic 842). This ASU requires a lessee to recognize a right-of-use asset and a lease liability on its balance sheet for most operating leases. ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018, including interim periods within those fiscal years. In July 2018, the FASB issued ASU 2018-11, “Leases (Topic 842): Targeted Improvements,” which provided companies with an additional optional transition method to apply the new standard to leases in effect at the adoption date through a cumulative effect adjustment. We adopted the new lease standard on January 1, 2019 using this optional transition method.

We elected the package of practical expedients referenced in ASU 2016-02, which permits companies to retain original lease identification and classification without reassessing initial direct costs for existing leases. We also elected (i) the practical expedient that exempts leases with an initial lease term of twelve months or less, (ii) the practical expedient that allows companies to select, by class of underlying asset, not to separate lease and non-lease components, and (iii) the practical expedient that allows companies to apply hindsight in determining lease terms. Our adoption of this standard resulted in the recognition of right-of-use assets and corresponding lease liabilities of $68.0 million and $69.1 million, respectively, as of January 1, 2019. There were no material impacts to our results of operations or our cash flows. Disclosures related to the amount, timing, and uncertainty of cash flows arising from our leases are included in Note 4.
