FutureFuel Chemical Company’s historical revenues have been generated through the sale of specialty chemicals. FutureFuel Chemical Company breaks its chemicals business into two main product groups: custom manufacturing and performance chemicals. Major products in the custom manufacturing group include: (i) nonanoyloxybenzenesulfonate, a bleach activator manufactured exclusively for The Procter & Gamble Company for use in a household detergent; (ii) a proprietary herbicide (and intermediates) manufactured exclusively for Arysta LifeScience North America Corporation, a major life sciences company; and (iii) two other product lines (CPOs and DIPBs) produced under conversion contracts for Eastman Chemical Company. The major product line in the performance chemicals group is SSIPA/LiSIPA, polymer modifiers that aid the properties of nylon manufactured for a broad customer base. There are a number of additional small volume custom and performance chemical products that FutureFuel Chemical Company groups into “other products”. In late 2005, FutureFuel Chemical Company began producing biodiesel as a product. Beginning in 2006, revenues and cost of goods sold for biofuels were treated as a separate business segment.
