Marsh has announced it will not accept controversial contingent commissions in its U.S. core insurance broking segment. The brokerage firm said it would refuse contingent commissions on any placements for any U.S. core broking operation clients, and will continue to provide detailed disclosure information on transactions, including all quotes received and compensation information.

However, Marsh & McLennan Agency LLC and Marsh Consumer's affinity sponsored program and personal lines businesses will accept contingent commissions. For these segments, the firm said it will provide plain language disclosure that meets or exceeds the New York Insurance Department's disclosure Regulation No. 194, as well as all other applicable legal and regulatory requirements.

The New York Department's rule, effective next year, followed a 2005 investigation that revealed large brokers had been taking hidden contingency fees to steer commercial clients to a group of insurers involved in a bid-rigging scheme. Marsh was among the brokers involved, and as as part of 2005 settlement agreements, said they would not accept contingent commissions.
