Arthur J Gallagher’s revenue and earnings rose in the second quarter, lifted by existing businesses and as it completed nine mergers in the period.

Chairman and CEO Patrick Gallagher says the company also expects to close the AssuredPartners transaction in the current quarter.

Last December, Gallagher announced a $US13.45 billion ($20.87 billion) deal to acquire the Florida broking group, which has offices in North America, the UK, Ireland and Belgium.

Mergers completed in the second quarter are estimated to provide annualised revenue of about $US290 million ($450 million).

Mr Gallagher says the company’s core brokerage and risk management segments delivered a 16% revenue increase, including organic growth of 5.4%.

“Overall, the global property and casualty insurance market remains rational, with competition across property lines and continued caution within casualty insurance products,” he said.

“Accordingly, we continue to see differences between property and casualty renewal premium changes, with property declining 7% and casualty increasing 8%.”

Total company net earnings for the quarter rose to $US366.2 million ($568.3 million) from $US285.4 million ($442.9 million) a year earlier.

Mr Gallagher says claims manager Gallagher Bassett’s daily revenue indications and claim counts are not indicating “a meaningful change” in customers’ business activity.
