Michigan Millers Mutual Sees Credit Ratings Boost from AM Best

AM Best has recently upgraded the Financial Strength Rating (FSR) of Michigan Millers Mutual Insurance Company, located in Lansing, Michigan. The rating has been elevated from A (Excellent) to A+ (Superior). Additionally, the Long-Term Issuer Credit Rating (Long-Term ICR) has been upgraded from “a” (Excellent) to “aa-” (Superior). This upgrade reflects the company’s robust financial standing and operational performance.
The outlook for these Credit Ratings has been revised from positive to stable. This change underscores AM Best’s assessment of Michigan Millers’ balance sheet strength, which is categorized as the strongest. The ratings also highlight the company’s strong operating performance, neutral business profile, and effective enterprise risk management practices.
These rating assignments come after regulatory approval and indicate Michigan Millers’ participation in the pooling agreement of Western National Insurance Pool (Western National), effective January 1, 2026. Along with this, a “p” reinsurance affiliation code has been assigned.
Michigan Millers will continue to play a vital role within the Western National Insurance Group, leveraging its expertise in commercial and specialty lines of business. The extension of Western National’s ratings to Michigan Millers is attributed to the significant reinsurance support that Michigan Millers receives from Western National. Notably, the current ratings of Western National’s affiliates remain unchanged, with an FSR of A+ (Superior) and Long-Term ICRs of “aa-” (Superior).
