Note 18: SEGMENT INFORMATION

SFAS No. 131,"Disclosure about Segments of an Enterprise and Related Information" requires disclosure of certain information about operating segments, geographic areas in which the Company operates, major customers, and products and services. In accordance with SFAS No. 131, the Company has determined it has four operating and three reportable segments: Fiberglass-Composite Pipe,Water Transmission and Infrastructure Products. The Fiberglass-Composite Pipe Group manufactures and markets filament-wound and molded composite fiberglass pipe, tubing, fittings and well screens. The Water Transmission Group manufactures and supplies concrete and steel pressure pipe, concrete nonpressure pipe, protective linings for pipe, and fabricated products including wind towers. The Infrastructure Products Group consists of two operating segments, the Pole Products and Hawaii Divisions, and manufactures and sells ready-mix concrete, sand and aggregates, concrete pipe and culverts, and concrete and steel lighting and traffic poles. In the prior periods, the Company included a fourth reportable segment, Performance Coatings & Finishes, which was sold August 1, 2006. The results from this segment have been reported as discontinued operations for all reporting periods. Each of these segments has a dedicated management team and is managed separately, primarily because of differences in products. TAMCO, the Company's equity method investment, is not included in any of these segments. The Company's Chief Operating Decision Maker is the Chief Executive Officer who primarily reviews sales and income before interest, income taxes and equity in earnings of joint venture for each operating segment in making decisions about allocating resources and assessing performance. The Company allocates certain selling, general and administrative expenses to operating segments utilizing assumptions believed to be appropriate in the circumstances. Costs of shared services (e.g., costs of Company-wide insurance programs or benefit plans) are allocated to the operating segments based on revenue,wages or net assets employed. Other items not related to current operations or of an unusual nature, such as adjustments to reflect inventory balances of certain steel inventories under the last-in, first-out ("LIFO") method, certain unusual legal costs and expenses, interest expense and income taxes, are not allocated to the reportable segments.

The markets served by the Fiberglass-Composite Pipe Group are worldwide in scope. The Water Transmission Group serves primarily the western U.S. The Infrastructure Products Group's quarry and ready-mix business operates exclusively in Hawaii, and poles are sold throughout the U.S. Sales for export or to any individual customer did not exceed 10% of consolidated sales in 2006, 2005 or 2004.

In accordance with SFAS No. 131, the following table presents information related to each operating segment included in, and in a manner consistent with, internal management reports. Inter-segment sales were not significant. Total assets by segment are those assets that are used exclusively by such segment. Unallocated assets are principally cash, corporate property and equipment, and investments. Long-lived assets consist of all long-term assets, excluding investments, goodwill, intangible assets, and deferred tax assets.
