In March the private equity firm Blackstone Group said it would buy CarrAmerica Realty for $5.6 billion--one of a series of deals in which a private equity player had acquired a public REIT or real estate company for the arbitrage opportunities, as well as greater operational flexibility, such a conversion could provide.
