Approved February 9, effective July 1. The Hanover raises its Massachusetts small-commercial package book 6.9% on average across 3,014 policyholders and $13.0M, but the class-level moves are what bite: medical facilities +21.6% liability, cultural institutions +17.1%, condominiums +17.0%, lessor's-risk +14.2%.
Adopting updated ISO loss costs and profitability-based class factors, the filing allows individual policy spikes as high as 39.8% — so a clean-loss medical or condo account can still see a number that looks nothing like the 6.9% average.
