Fortune’s “Most Admired Companies” list is compiled from a database of roughly 1,400 of the nation’s largest companies (by revenue). Fortune then uses The Hay Group to survey approximately 15,000 senior executives, outside directors and other major non-U.S. companies and financial analysts. Companies are rated on innovation, people management, use of corporate assets, social responsibility, quality of management, financial soundness, long-term investment and quality of products/services.
