The giant toy retailer is just one of several portfolio holdings vulnerable in a recession.
2008 Rank: 4
2007 Rank: 5
Recent buyout fundraising: $21 billion

Founded by a consulting firm, Bain believes that its intensive due diligence merits a 30% take rather than the standard 20% of profit.

In the past, the Boston-based shop has justified the heftier cut for the way it added value to strong retail brands that were stuck with middling business models. Domino's Pizza, for example, went public in 2004 at a price that quintupled Bain's equity investment.

Headwind issue: As consumers cut back in a recession, several companies in Bain's portfolio, including Toys "R" U s, Guitar Center, and Outback Steakhouse, are vulnerable. The debt from all of those deals is trading at distress prices.

Worth noting: Bain's partners are sports nuts. Several of them are co-owners of the Celtics. They are invested in the Tennis Channel and have run a children's charity golf tournament for the past 11 years. Partner Joshua Bekenstein even put up the cash for Yale's basketball and volleyball courts.

Source: Rankings are based on a firm's most recently raised buyout fund(s). Fortune looked at data from Capital IQ, institutional investors, and the companies themselves to determine the size of the most recently raised buyout funds. For some firms that means a fund that was raised in 2007; for others it might be 2006. Whatever the date, the most recent fund was the one we counted. In the case of companies that raise multiple funds simultaneously as opposed to raising a single fund at a time, we chose to count only those private equity funds that were not raised in public markets and that were earmarked for buyouts (as opposed to investments in debt, venture capital, or other ventures).
