July 30 (Reuters) - Arthur J. Gallagher ( AJG ) posted a

rise in second-quarter profit on Thursday, driven by higher fees

and commissions as strong demand for insurance supported client

spending.

Insurance demand stayed strong as companies and individuals

sought coverage against losses from natural catastrophes, cyber

threats, conflicts and other unexpected events.

Here are some details:

* Insurance brokerages act as intermediaries between

insurers and customers, helping clients choose policies that

best suit their coverage needs.

* Commissions in brokerage segment surged 35% over the year

earlier to $2.44 billion during the quarter, while fees jumped

27.5%.

* "In an increasingly complex risk environment, client

demand for our advice, analytics, market access, specialty

expertise and claims advocacy remains robust," CEO J Patrick

Gallagher Jr. said in a statement.

* Adjusted net income rose to $734 million, or $2.84 per

share, in three months ended June 30, from $604 million, or

$2.30 per share, a year earlier.
