Refco

Refco was a New York-based financial services company, primarily known as a broker of commodities and futures contracts. It was founded in 1969 as "Ray E. Friedman and Co." Prior to its collapse in October, 2005, the firm had over $4 billion in approximately 200,000 customer accounts, and it was the largest broker on the Chicago Mercantile Exchange. The firm's balance sheet at the time of the collapse showed about $75 billion in assets and a roughly equal amount in liabilities. Though these filings have since been disowned by the company, they are probably roughly accurate in showing the firm's level of leverage.
