Marsh & McLennan Cos Inc said on Monday that it plans to sell Kroll, a risk consulting firm, to Altegrity in a $1.13 billion deal.

Kroll, put up for sale by the No. 2 global insurance broker MMC, attracted interest from a number of private equity firms, with Altegrity emerging as the winner.

Altegrity, which is owned by Providence Equity Partners, plans to acquire Kroll in an all-cash transaction. The deal is expected to close by late September.

The Financial Times reported in March that MMC was seeking $1.3 billion for Kroll.

Altegrity Chief Executive Mike Cherkasky served as president and CEO of Kroll from 2001 to 2004.

Kroll, headquartered in New York, provides investigative, intelligence, financial, security, and technological services to clients. It has more than 3,000 employees.

MMC said Goldman Sachs Group Inc and Apollo Investment Corp are providing debt financing for the transaction.
