Strengths: The diversified financial firm invests in companies, real estate, mortgages, and debt. Blackstone made $410 million last year advising companies on mergers, acquisitions, and restructurings.

Founders: David Rubenstein, Daniel D'Aniello, William Conway Jr.; Assets: $85.5 billion
Strengths: Carlyle uses its political clout to land deals. Former President George H.W. Bush and former Secretary of State James Baker III are among those who have worked for the firm.
Weaknesses: New York Attorney General Andrew Cuomo is investigating whether Carlyle influenced pension fund managers to snag more business.
Founders: Mitt Romney and seven partners; Assets: $60 billion
Strengths: Turnaround artists known for their strong management skills, the firm bought a 93% stake in Domino's Pizza in 1998 and sold it to the public six years later, returning 400% to investors.
Weaknesses: Bain's portfolio is filled with troubled retailers, including craft chain Michaels and Guitar Center.
Kohlberg, Kravis, & Roberts
Founders: Henry Kravis & George Roberts; Assets: $55 billion
Strengths: The firm—whose 1989 takeover of RJR Nabisco inspired the book Barbarians at the Gate—is poised to capitalize on infrastructure spending. It also is eyeing a South Korean brewer.

Chairman: David Bonderman; Assets: $50 billion
Strengths: A specialist in reviving floundering businesses, TPG could scoop up assets in Chapter 11. The firm is skilled at collecting fees from its portfolio companies up front.
Weaknesses: TPG lost $1.7 billion on its investment in Washington Mutual, which was seized by regulators and sold to JPMorgan Chase.
Chairman: Leon Black; Assets: $45.1 billion
Strengths: With hundreds of names in its portfolio, Apollo can weather the downturn. One holding, big-box grocery store Smart & Final, is surging as consumers look for discounts.
Weaknesses: Apollo has plenty of clunkers among its companies, including Harrah's and Realogy.
