The accompanying unaudited condensed consolidated financial statements include the accounts of Lufkin Industries, Inc. and its consolidated subsidiaries (the "Company") and have been prepared pursuant to the rules and regulations for interim financial statements of the Securities and Exchange Commission. Certain information in the notes to the consolidated financial statements normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America has been condensed or omitted pursuant to these rules and regulations for interim financial statements. In the opinion of management, all adjustments, consisting of normal recurring accruals unless specified, necessary for a fair presentation of the Company's financial position, results of operations and cash flows for the interim periods included in this report have been included. For further information, including a summary of major accounting policies, refer to the consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2011. The results of operations for the three months ended March 31, 2012, are not necessarily indicative of the results that may be expected for the full fiscal year.

The Company's financial instruments include cash, accounts receivable, accounts payable, invested funds and debt obligations. The book value of accounts receivable, short-term debt and accounts payable are considered to be representative of their fair market value because of the short maturity of these instruments. The Company's accounts receivable does not have an unusual credit risk or concentration risk.
