Pekin Insurance is seeking approval for a rate and rule update to its Wisconsin commercial property line, effective April 23, 2026, for new and renewal business.

The filing introduces a multiplicative rating factor for buildings and business personal property, powered by Octagram’s FireRQ model. The model uses 1.5 million U.S. fire events to generate address-level risk scores, benchmarking each risk against similar occupancies.

The update impacts 1,390 policyholders and $3.3 million in premium. The last revision was essentially flat, with a -0.010% change effective August 24, 2025.

A similar filing was submitted for its BOP product in Wisconsin, affecting 487 policyholders and $1.9 million in written premium. The last revision was a -0.3% decrease effective May 5, 2026.
