Guy Carpenter


Guy Carpenter & Company, LLC is a 1922-founded company described as "a leading global risk and reinsurance specialist" subsidiary of Marsh & McLennan Companies acquired by MMC in 1923.
One area in which Guy Carpenter has recently added to its array of services is InsurTech.
Another area is "Cyber insurance", working with Symantec to measure "severity and frequency."
In February 2020, Guy Carpenter & Company entered into a multi-year agreement with Karen Clark and Company to license its catalogue of natural catastrophe models, analytics and execution software.

Founder

Guy Carpenter founded his company in 1922 and personally concluded a merger with MMC founders Henry W. Marsh and Donald R. McLennan about a year later.
Concurrently he was the manager of Atlanta-based Cotton Insurance Association, which had been organized in 1905.
His "Carpenter Plan" was based on using a rolling average of losses, over a period of years, rather than simply looking at the prior year.

Result

One result was that insurance contracts were focused more on what was not covered. Carpenter's contracts were more inclusive - the focus was on what was excluded.
Fire insurance paid for the damage resulting from a fire.
An example of how this did not work was the following:
By the time of this injustice, Carpenter's plan, which he had discussed with Lloyd's of London in 1915, was beginning to take root.
