Nature of Operations and Basis of Presentation Description of Business and Organization — Headwaters Incorporated (Headwaters) is a building products company incorporated in Delaware, providing products and services in the light and heavy building materials sectors. Headwaters’ vision is to improve lives through innovative advancements in construction materials. The light building products segment designs, manufactures, and sells a wide variety of building products, including exterior vinyl siding accessories (such as shutters, mounting blocks, and vents), manufactured architectural stone and concrete block. Headwaters believes that many of its branded products have a leading market position. Revenues from Headwaters’ light building products businesses are diversified geographically and also by market, including the new housing and residential repair and remodeling markets, as well as commercial construction markets. The heavy construction materials segment is the nationwide leader in the management and marketing of coal combustion products (CCPs), including fly ash which is primarily used as an admixture for the partial replacement of portland cement in concrete. Headwaters’ heavy construction materials business is comprised of a nationwide supply, storage and distribution network. Headwaters also provides services to electric utilities related to the management of CCPs. The energy technology segment has been focused on reducing waste and increasing the value of energy-related feedstocks, primarily in the areas of low-value coal and oil. In coal, Headwaters owned and operated coal cleaning facilities that separate ash from waste coal to provide a refined coal product that is higher in Btu value and lower in impurities than the feedstock coal. As described in Note 3, Headwaters disposed of its remaining coal cleaning facilities in January 2013 and they are reflected as assets held for sale in the accompanying consolidated balance sheets. The results of Headwaters’ coal cleaning operations have been presented as discontinued operations for all periods presented. In oil, Headwaters believes that its upgrading technology represents a substantial improvement over current heavy oil refining technologies. Headwaters’ heavy oil upgrading process uses a liquid catalyst precursor to generate a highly active molecular catalyst to convert low-value residual oil into higher-value distillates that can be further refined into gasoline, diesel and other products.

All significant intercompany transactions and accounts are eliminated in consolidation. Due to the seasonality of most of Headwaters’ operations and other factors, the consolidated results of operations for any particular period are not indicative of the results to be expected for a full fiscal year.
