Key Differences in Commercial Property Insurance
Property Detail and Fit
USI identifies property analysts and risk-control specialists for commercial property clients, while Marsh McLennan Agency describes tailored placement and an adviser contact route. 3 5
USI says its property-and-casualty team uses dedicated property analysts and risk-control specialists with its USI ONE analytics process to target property exposures. Marsh McLennan Agency’s overview describes tailoring commercial property to industry and stated risks but does not detail an equivalent analytics or risk-control service. Ask both what pre-bind property review they will provide and who conducts it. 3 5
Placement and Buyer Process
USI separately identifies property, business income and contingent business income placement for technology clients, serving companies from seed stage through IPO. Marsh McLennan Agency’s overview does not specify these components or a technology segment. A technology company should ask whether off-premises equipment and interruption at a service provider can be included, and request the limits for each coverage part. 3 5
