A.M. Best

A.M. Best is an American credit rating agency and information provider that specializes in the insurance industry. Founded in 1899, it produces financial strength ratings, credit opinions, research, and data covering insurance companies, brokers, reinsurers, and risk-bearing entities. The firm is regarded as one of the major specialist ratings organizations in global insurance markets alongside generalist agencies and rating services.

History

The firm traces origins to Alfred M. Best, an entrepreneur active during the Progressive Era who established a periodical focused on casualty, life, and marine underwriting akin to how John D. Rockefeller transformed Standard Oil and how industrialists like Andrew Carnegie influenced Carnegie Steel Company—but concentrated on actuarial and solvency information for insurers. Over the 20th century the organization expanded during regulatory and market shifts influenced by events such as the Great Depression, the passage of the McCarran-Ferguson Act, and the rise of modern reinsurance markets epitomized by exchanges in Bermuda and London. During the postwar era, developments like the creation of AIG and the international growth of firms such as Allianz, AXA, Zurich Insurance Group, and Munich Re broadened demand for insurer-specific analysis, prompting geographic expansion into Europe, Asia, and Latin America. High-profile insurance crises and catastrophes—examples including losses from Hurricane Katrina, the September 11 attacks, and large corporate insolvencies such as Lehman Brothers related disruptions—shaped methodological evolution and regulatory dialogue with bodies like the National Association of Insurance Commissioners and supranational entities including the International Association of Insurance Supervisors.

Ratings and Methodology

The organization issues a range of ratings and opinions focused on insurer creditworthiness and financial strength, comparable in market role to the work of Moody's Investors Service, Standard & Poor's, and Fitch Ratings but specialized for underwriting risk. Methodologies incorporate quantitative metrics—balance sheet capital, statutory surplus, investment portfolio exposures—and qualitative assessments—management quality, enterprise risk management, reinsurance program robustness—paralleling analytical approaches used by institutions such as Goldman Sachs, JPMorgan Chase, and BlackRock when evaluating corporate counterparties. Stress scenarios often reference market shocks observed during events like the 2008 financial crisis and natural catastrophe models used by vendors like RMS and AIR Worldwide. The agency publishes criteria and surveillance procedures akin to reporting practices at Federal Reserve Board-monitored banks and engages peer review similar to processes at International Accounting Standards Board for transparency. Rating actions affect reinsurance counterparties, bank collateral arrangements with entities such as Deutsche Bank and Citigroup, and regulatory capital calculations that interact with solvency frameworks like Solvency II and local statutory regimes.

Corporate Structure and Governance

The firm operates as a privately held company with executive leadership, a board of directors, and governance practices emphasizing independence of analytical staff from commercial functions, mirroring governance themes relevant to firms such as Berkshire Hathaway and Munich Re. Oversight mechanisms include internal committees for ratings policy, ethics, and conflicts of interest, drawing comparison to compliance structures at Ernst & Young and Deloitte. The company maintains regional offices and affiliates to serve markets in Tokyo, Singapore, London, and São Paulo, coordinating with global regulatory agencies including the European Insurance and Occupational Pensions Authority and national supervisors like the Financial Conduct Authority. Corporate governance has been scrutinized in contexts similar to debates around the independence of rating organizations exemplified by historical scrutiny of Moody's and Standard & Poor's.

Products and Services

Core offerings include financial strength ratings, issuer credit ratings, ratings of insurance-linked securities, and performance analytics used by insurers such as MetLife, Prudential Financial, State Farm, and Chubb. The firm also publishes news, commentary, statistical databases, and subscription-based data feeds utilized by asset managers, reinsurers, brokers like Marsh McLennan and Aon, and institutional investors including Vanguard and BlackRock. Additional services encompass bespoke benchmarking, warranty of actuarial reporting comparable to actuarial service lines at firms such as Willis Towers Watson, and events and conferences that convene practitioners from entities like Swiss Re and Hiscox. Research outputs inform rating triggers in insurance-linked securities sold to capital market participants including hedge funds and pension funds such as CalPERS.

Market Influence and Criticism

The agency exerts influence on capital allocation, underwriting behavior, and regulatory capital through ratings that affect insurer cost of capital, reinsurance pricing, and market access—roles analogous to those historically ascribed to Moody's and Standard & Poor's in debt markets. Criticisms mirror broader debates about rating agencies: potential conflicts of interest in issuer-paid models, procyclicality during market stress as observed in the 2008 financial crisis, and the limits of ratings in forecasting insolvency during systemic shocks like Hurricane Maria. Academic and industry critiques have invoked comparative studies involving Harvard, Stanford, and London School of Economics researchers, while regulatory scrutiny has referenced reforms similar to post-crisis oversight applied to other credit rating providers. Ongoing dialogue involves market participants such as Insurance Europe, reinsurers, and sovereign regulators about transparency, methodological enhancements, and incorporation of emerging risks such as cyber exposures highlighted by incidents involving Equifax and complex catastrophe scenarios modeled by NASA-funded research.
