The Coalition for Derivatives End-Users, organized by groups such as the U.S. Chamber of Commerce, the Business Roundtable and the National Association of Manufacturers, sent a letter to lawmakers last week saying that "some reform proposals would place an extraordinary burden on end-users of derivatives in every sector of the economy -- including manufacturers, energy companies, utilities, healthcare companies and commercial real estate owners and developers." The letter was signed by more than 170 companies and trade associations. "We definitely think the administration's proposal went too far," said Ryan McKee, senior director of the Chamber's Center for Capital Markets Competitiveness. "End users were not part of the problem. They don't pose systemic risk. They are not profiting from these transactions. They are not speculating."
