BERKSHIRE HATHAWAY INC Annual Report, Year Ended Dec 31, 2005

Filed March 13, 2006For Securities:BRK-BBRK-A

Summary

Berkshire Hathaway Inc.'s 2005 10-K filing reveals a diversified conglomerate with a strong emphasis on its insurance and reinsurance operations, which form the core of its "float" for investment purposes. The company, led by Warren Buffett, demonstrated robust financial performance in 2005, with total revenues exceeding $81 billion. Key to its success is the decentralized management style, allowing subsidiaries significant operational autonomy while corporate headquarters focuses on capital allocation. The insurance segment, comprising GEICO, General Re, Berkshire Hathaway Reinsurance Group, and Berkshire Hathaway Primary Group, generated substantial investment income and underwriting gains, despite significant catastrophe losses from Hurricanes Katrina, Rita, and Wilma. The company's commitment to maintaining "exceptionally high" capital strength in its insurance subsidiaries, reflected in AAA and A++ ratings, underpins its competitive advantage. Beyond insurance, Berkshire Hathaway operates a wide array of non-insurance businesses, including apparel, building products, finance and financial products, flight services, McLane Company, retail operations, Shaw Industries, and utilities and energy. The company's strategic acquisitions, such as Clayton Homes and Medical Protective Company in recent years, continue to broaden its business portfolio. The filing also highlights the company's significant investments in publicly traded companies and its ongoing management of market risks, particularly those related to interest rates, equity prices, and foreign currency exchange rates.
