1. | Basis of Presentation
The Condensed Consolidated Financial Statements include the accounts of Northwest Pipe Company (the “Company”) and its subsidiaries over which the Company exercises control as of the financial statement date. Intercompany accounts and transactions have been eliminated. The Company operates in one business segment, Water Transmission, which manufactures large-diameter, high-pressure, engineered welded steel pipeline systems, as well as reinforced concrete pipe and protective linings, for use in water infrastructure applications, which are primarily related to drinking water systems. These products are also used for hydroelectric power systems, wastewater systems and other applications. In addition, the Company makes products for industrial plant piping systems and certain structural applications. The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The financial information as of December 31, 2017 is derived from the audited Consolidated Financial Statements presented in the Company’s Annual Report on Form 10 -K for the year ended December 31, 2017 (the “2017 Form 10 -K”). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission. In the opinion of management, the accompanying Condensed Consolidated Financial Statements include all adjustments necessary (which are of a normal and recurring nature) for the fair statement of the results of the interim periods presented. The Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Notes thereto together with management’s discussion and analysis of financial condition and results of operations contained in the Company’s 2017 Form 10 -K. Certain amounts from the prior year financial statements have been reclassified in order to conform to the current year presentation. Operating results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the entire fiscal year ending December 31, 2018.
