"Take a typical Bain transaction involving an Indiana-based company called American Pad and Paper. Bain bought Ampad in 1992 for just $5 million, financing the rest of the deal with borrowed cash. Within three years, Ampad was paying $60 million in annual debt payments, plus an additional $7 million in management fees. A year later, Bain led Ampad to go public, cashed out about $50 million in stock for itself and its investors, charged the firm $2 million for arranging the IPO and pocketed another $5 million in "management" fees. Ampad wound up going bankrupt, and hundreds of workers lost their jobs, but Bain and Romney weren’t crying: They’d made more than $100 million on a $5 million investment."
