AM Best Upgrades Credit Ratings of Illinois Casualty and Lebanon Valley

According to the rating agency’s announcement, the Financial Strength Rating (FSR) for Illinois Casualty Company (ICC) and Lebanon Valley Insurance Company (LV) has been upgraded to A (Excellent) from A- (Excellent). Concurrently, their Long-Term Issuer Credit Ratings (Long-Term ICRs) were elevated to “a” (Excellent) from “a-” (Excellent). Following these positive rating adjustments, AM Best has also revised the outlook for both companies’ credit ratings to stable from positive, signaling a period of anticipated operational stability and sustained financial health.

Both Illinois Casualty Company and Lebanon Valley Insurance Company are domiciled in Rock Island, Illinois. The recent rating upgrades arrive in tandem with AM Best’s affirmation of the financial strength and issuer credit ratings of their affiliate entities within the wider insurance group. Specifically, AM Best affirmed the FSR of A (Excellent) and the Long-Term ICRs of “a” (Excellent) for Tuscarora Wayne Insurance Company (TW) and its affiliate, Keystone National Insurance Company. The outlook for these affirmed ratings remains stable, underscoring the consistent financial performance of the broader enterprise. Tuscarora Wayne Insurance Company and Keystone National Insurance Company are domiciled in Wyalusing, Pennsylvania.

Together, these four entities—Illinois Casualty Company, Lebanon Valley Insurance Company, Tuscarora Wayne Insurance Company, and Keystone National Insurance Company—are collectively recognized within the insurance and financial sectors as the Mutual Capital Insurance Group, or simply the group. This collective identity highlights the shared strategic vision, integrated management principles, and mutualized support systems that bind the operating companies together across their respective domiciliary states in Illinois and Pennsylvania.

AM Best’s evaluation of Mutual Capital Insurance Group encompasses several fundamental pillars of insurance company assessment. The group’s comprehensive credit ratings are anchored by its balance sheet strength, which AM Best evaluates as very strong. This robust balance sheet assessment is supported by prudent capital management, conservative investment strategies, and adequate reserving practices designed to weather potential economic volatility and catastrophic loss events within the property and casualty insurance markets. Furthermore, the group’s credit profile is bolstered by an adequate operating performance that demonstrates consistent underwriting discipline and steady investment yields over time.

In addition to financial capitalization and operating earnings, AM Best categorized Mutual Capital Insurance Group’s business profile as neutral. This reflects the group’s established market presence within its operational footprint, balanced geographic diversification across its operating territories, and a focused approach to regional commercial and personal lines underwriting. The enterprise risk management (ERM) framework maintained by the group was assessed as appropriate, demonstrating that management has established effective mechanisms to identify, measure, monitor, and control the various underwriting, financial, and operational risks inherent in the property and casualty insurance sector.

The strategic catalyst behind the rating upgrades for Illinois Casualty Company and Lebanon Valley Insurance Company involves a significant corporate realignment within the group. The rating enhancements follow the recent regulatory approval of a comprehensive intercompany pooling agreement established between Tuscarora Wayne Insurance Company, Lebanon Valley Insurance Company, and Illinois Casualty Company. This intercompany pooling arrangement is scheduled to become officially effective on July 1, 2026.

The decision by AM Best to elevate the financial strength and issuer credit ratings of ICC and LV is directly rooted in the rating agency’s forward-looking expectations regarding the enhanced integration of the group. As pooled members of Mutual Capital Insurance Group, the business profiles of both Illinois Casualty Company and Lebanon Valley Insurance Company are anticipated to be substantially strengthened. Intercompany pooling agreements typically allow insurance groups to share risks, capital resources, and underwriting capacity more efficiently across all participating member companies, thereby dampening individual volatility and bolstering overall financial security for policyholders and commercial partners alike.

By streamlining operations and sharing liabilities under the newly approved pooling structure, ICC and LV will benefit from the collective financial backing and stability of the entire Mutual Capital Insurance Group enterprise. As the effective date of July 1, 2026, approaches, the stable outlook assigned by AM Best reflects confidence that the transition will be executed smoothly, allowing the group to continue delivering dependable insurance solutions while maintaining its strong capital adequacy and disciplined risk management standards.
