NEW YORK (Bloomberg) - New York Insurance Superintendent Eric Dinallo proposed new regulations that would force insurance brokers to disclose fees they receive from carriers, a move welcomed by the industry's largest middlemen.

The proposal has been circulated to industry and consumer groups and companies for comment, said Matt Gaul, special counsel to the insurance department, in an interview on Thursday.

Mr. Dinallo called hearings last year to review fees paid to smaller firms after the largest brokers complained they were at an unfair disadvantage since agreeing in 2005 not to accept such payments. Brokers help corporate clients shop for coverage, earning commissions from insurance buyers.

The three largest insurance brokers, Aon Corp., Marsh & McLennan Cos. and Willis Group Holdings Ltd., said they supported the efforts of the New York regulator to bring greater transparency to broker pay and wanted identical rules for all companies that arrange insurance coverage.

"While the draft rules are a step in the right direction, and we commend the superintendent for issuing them, we do not think they go nearly far enough," Aon spokesman David Prosperi said in an e-mailed statement.

Marsh & McLennan CEO Brian Duperreault said his firm wants to "work closely with the New York authorities to establish an equitable regulatory landscape that serves the interests of all clients".
