This amendment, Congress believed, would prevent any unintended application of any of the subsections of section 1233 to bona fide hedging transactions. In 1955, the limited concept of hedging, with its strict requirements of balanced market position and relationship of the commodity future to the business operations of the taxpayer, was blurred by the decision in Corn Products Refining Co. v. Commissioner, 350 U.S. 46 (1955), affg. 215 F.2d 513 (2d Cir. 1954), affg. 16 T.C. 395 (1951), as supplemented 20 T.C. 503 (1953). In Corn Products, the taxpayer was engaged in the production of distilled products from corn.
