Marsh & McLennan companies reported revenues from risk and insurance services up by 17% to $1.4bn (£904m) in the third quarter from $1.2bn (£775m) in the same period last year.
The results underlined the extent to which a hardening insurance market can be profitable for brokers.
Earnings from insurance services were the main driver behind an increase in net income to $299m (£193m) for the quarter from $168m (£109m) for the same time last year.
The worldwide broking group's risk and insurance operations pulled in revenues of $4.3bn (£2.78bn) in the first nine months of 2002 compared to $3.8bn (£2.5bn) in the same period last year.
Revenues from investment management declined and there was a small increase in those from consulting.
Operating income rose to $512m (£331m) in the third quarter from $312m (£201m) the time before and over nine months to $1.8bn (£1.2bn) from $1.5bn (£969m) the time before.
Basic net income per share increased in the third quarter to 56 cents from 31 cents the time before and over nine months to $1.94 from $1.51.
Chairman Jeffrey W Greenberg said: "Risk and insurance services performed well for clients in a difficult insurance market and generated excellent results for shareholders ."
