Grinnell Mutual Reinsurance Company, SI, submitted a form filing in Illinois on October 8, 2025, to update its Multi Line Personal (MLP) forms and revise the application for Owners, Landlords, and Tenants Personal Liability coverage. The independent filing, effective June 1, 2026, for both new and renewal business, reflects a company name change associated with its mutual holding company structure.

The revised application clarifies that property coverage is written through a separate farm mutual while liability coverage is provided by Grinnell Mutual Reinsurance Company, SI. It also specifies that credit scoring data may be used to determine eligibility or premium, potentially through a third-party provider.
