<div id="readability-page-1"><article>OLDWICK, N.J.--(BUSINESS WIRE)--AM Best has affirmed the Financial Strength Rating (FSR) of A+ (Superior) and the Long-Term Issuer Credit Ratings (Long-Term ICR) of “aa-” (Superior) of Great American Insurance Company and its pooling affiliates, collectively referred to as Great American Insurance Companies (Great American). Concurrently, AM Best has affirmed the Long-Term ICR of “a-” (Excellent) and the Long-Term Issue Credit Ratings (Long-Term IRs) of American Financial Group, Inc. (AFG) [NYSE: AFG]. The outlook of these Credit Ratings (ratings) is stable.At the same time, AM Best has affirmed the FSR of A+ (Superior) and the Long-Term ICRs of “aa-” (Superior) of the property/casualty (P/C) members of the Great American Contemporary Pool (collectively, Great American Contemporary). The outlook of these ratings is stable. The Republic companies within Great American Contemporary are headquartered in Calabasas, CA, and most Bridgefield companies are headquartered in Lakeland, FL.AM Best also has affirmed the FSR of A+ (Superior) and the Long-Term ICRs of “aa-” (Superior) of the P/C members of the Mid-Continent Group (Mid-Continent) (headquartered in Tulsa, OK). Additionally, AM Best has affirmed the FSR of A+ (Superior) and the Long-Term ICRs of “aa-” (Superior) of National Interstate Insurance Company (headquartered in Richfield, OH) and its affiliates (collectively referred to as National Interstate). The outlook of these ratings is stable.All companies are subsidiaries of AFG and headquartered in Cincinnati, OH, unless otherwise specified. (Please see below for a detailed listing of the P/C companies and ratings.)The ratings of Great American reflect its balance sheet strength, which AM Best assesses as very strong, as well as its strong operating performance, favorable business profile and appropriate enterprise risk management (ERM). Great American’s ratings are aided by risk-adjusted capitalization assessed at the very strong level, as measured by Best’s Capital Adequacy Ratio (BCAR), with minimal volatility over time. Great American also has shown consistent operating performance on par with peers similarly assessed at the strong level, which is reflective of its profitable underwriting results that are supported by underwriting focus and their vast expertise within a diversified product portfolio and business profile through its multiple distribution platforms, in addition to significant investment income. An offsetting factor is a high dividend payout ratio to the parent company in alignment with the capital management strategies of the parent company.The ratings of Great American Contemporary reflect its balance sheet strength, which AM Best assesses as very strong, as well as its strong operating performance, neutral business profile and appropriate ERM. The ratings of Great American Contemporary also reflect rating lift from the lead rating unit, Great American, based on historical capital support and shared services. The combined pool member entities maintain risk-adjusted capitalization currently at the strongest level, as measured by BCAR, which is supported by consistently strong operating performance over the past five years that has outperformed composite peers. Despite its narrow focus in the workers’ compensation segment, the group is among the market leaders in its focused geographic areas; in particular, the group’s members rank as the second-largest workers’ compensation provider in Florida through an extensive network of independent agents and advisers. The group remains concentrated in Florida and California, which exposes it to potential regulatory and legislative risks. The group members also maintain higher underwriting leverage than peers with a high dividend payout to its parent, which has tempered surplus growth.The ratings of Mid-Continent reflect its balance sheet strength, which AM Best assesses as very strong, as well as its adequate operating performance, neutral business profile and appropriate ERM. The ratings also reflect rating lift from the lead rating unit, Great American, recognizing the historical support and services. Mid-Continent’s ratings are supported by risk-adjusted capitalization assessed at the strongest level, as measured by BCAR, and consistent ability to maintain balance sheet metrics with positive organic operating earnings. These factors are offset by Mid-Continent’s more-concentrated industry segments in construction and energy adjacent segments, as well as its limited geographic profile, which exposes it to increased regulatory, legislative and competitive risks.The ratings of National Interstate reflect its balance sheet strength, which AM Best assesses as very strong, as well as its strong operating performance, neutral business profile and appropriate ERM. The ratings also reflect lift from the lead rating unit, Great American, recognizing the historical support and services. National Interstate’s ratings are supported by risk-adjusted capitalization assessed at the strongest level, as measured by BCAR, a prudent investment portfolio and high quality of reinsurance partners. The group maintains significant expertise in its niche-focused market of captive risk transfer products for the transportation market. Despite this limited focus, the group has demonstrated consistent favorable operating results on par with peers through continued strong underwriting results. Offsetting factors around this limited focus expose the group to increased regulatory, legislative and competitive risks.Each of the groups discussed above also benefits from the financial flexibility provided by AFG, which has additional liquidity sources given its access to capital markets and lines of credit. AM Best anticipates that earnings and cash flows from AFG’s operating subsidiaries will allow it to support risk-adjusted capitalization at the operating level should the need arise, which has been demonstrated in the past. At the same time, surplus growth at each group has been limited over the past five years by the payment of significant stockholder dividends to AFG. These dividends vary based on capital requirements at the various subsidiaries. AFG’s financial leverage is maintained at between 25-30%, which is within AM Best’s criteria tolerance levels and continues to be supportive of the ratings. AFG also maintains strong coverage ratios that remain more than sufficient to the ratings.The FSR of A+ (Superior) and the Long-Term ICRs of “aa-” (Superior) have been affirmed, each with a stable outlook, for Great American Insurance Company and its following pooled affiliates:<ul><li>Great American Alliance Insurance Company</li><li>Great American Assurance Company</li><li>Great American Casualty Insurance Company</li><li>Great American E &amp; S Insurance Company</li><li>Great American Fidelity Insurance Company</li><li>Great American Insurance Company of New York</li><li>Great American Protection Insurance Company</li><li>Great American Security Insurance Company</li><li>Great American Spirit Insurance Company</li><li>American Empire Insurance Company</li><li>Great American Risk Solutions Surplus Lines Insurance Company</li></ul>The FSR of A+ (Superior) and the Long-Term ICRs of “aa-” (Superior) have been affirmed, each with a stable outlook, for the following P/C insurance members of Mid-Continent Group:<ul><li>Mid-Continent Assurance Company</li><li>Mid-Continent Casualty Company</li><li>Oklahoma Surety Company</li><li>Mid-Continent Excess and Surplus Insurance Company</li></ul>The FSR of A+ (Superior) and the Long-Term ICRs of “aa-” (Superior) have been affirmed, each with a stable outlook, for the following P/C members of National Interstate Group:<ul><li>National Interstate Insurance Company</li><li>National Interstate Insurance Company of Hawaii, Inc.</li><li>Triumphe Casualty Company</li><li>Vanliner Insurance Company</li></ul>The FSR of A+ (Superior) and the Long-Term ICRs of “aa-” (Superior) have been affirmed, each with a stable outlook for the following P/C members of Great American Contemporary Pool:<ul><li>Great American Contemporary Insurance Company</li><li>Republic Indemnity Company of America</li><li>Republic Indemnity Company of California</li><li>Bridgefield Casualty Insurance Company</li><li>Bridgefield Employers Insurance Company</li><li>Bridgefield Indemnity Insurance Company</li></ul>The Long-Term ICR of “a-” (Excellent) has been affirmed with a stable outlook for American Financial Group, Inc.The following Long-Term IRs have been affirmed with stable outlooks:American Financial Group, Inc. — -- “a-” (Excellent) on $350 million 5% senior unsecured notes, due 2035 -- “bbb+” (Good) on $200 million 4.5% subordinated debentures, due 2060 -- “bbb+” (Good) on $150 million 5.625% subordinated debentures, due 2060 -- “bbb+” (Good) on $125 million 5.875% subordinated debentures, due 2059 -- “bbb+” (Good) on $200 million 5.125% subordinated debentures, due 2059 -- “a-” (Excellent) on $590 million 4.5% senior unsecured notes, due 2047 (of which $567 million remains outstanding) -- “a-” (Excellent) on $300 million 5.25% senior unsecured notes, due 2030 (of which $253 million remains outstanding)The following indicative Long-Term IRs have been affirmed with stable outlooks under the shelf registration:American Financial Group, Inc.— -- “a-” (Excellent) on senior unsecured debt -- “bbb+” (Good) on subordinated debt -- “bbb” (Good) on preferred stockAmerican Financial Capital Trust II, III &amp; IV— -- “bbb” (Good) on preferred securitiesThis press release relates to Credit Ratings that have been published on AM Best’s website.
