(Reuters) - Insurance brokerage Brown & Brown ( BRO ) reported a 13% rise in first-quarter profit on Monday, benefiting from higher income from commissions and fees.

Insurance brokerages, such as Brown & Brown ( BRO ), serve as a bridge between an insurer and customers, helping clients find a policy that best suits their needs. Unlike insurers, they do not directly sell policies.

Brokers like Brown & Brown ( BRO ) benefit as consumers buy more insurance product, earning revenue on the sale of such products.

The company's commissions and fees jumped 12% to $1.39 billion in the three months ended March 31.

The company's investment and other income, however, dropped to $19 million in the reported quarter from $21 million in the year-ago period.

Earlier this month, peer Marsh McLennan's beat Wall Street estimates for first-quarter profit.

Brown & Brown ( BRO ) is one of the largest independent insurance brokerages in the U.S. specializing in risk management. It operates through four business segments - retail, national programs, wholesale brokerage and services.

Net profit attributable to Brown & Brown ( BRO ) rose to $331 million, or $1.15 per share, in the January-to-March quarter, compared with $293 million, or $1.02 per share, last year.

Brown & Brown ( BRO ), which specializes in risk management, reported an 11.6% jump in total revenue to $1.40 billion.

In February, the company named former Willis Re and Inver Re CEO Steve Hearn as chief operating officer.
