Berkshire Hathaway, the $300 billion conglomerate that Warren Buffett built, is among the world's largest and most famous corporations. Yet, for all its power and celebrity, few people understand Berkshire, and many assume it cannot survive without Buffett. This book proves that assumption wrong. In a comprehensive portrait of the distinct corporate culture that unites and sustains Berkshire's fifty direct subsidiaries, Lawrence A. Cunningham unearths the traits that assure the conglomerate's perpetual prosperity. Riveting stories recount each subsidiary's origins, triumphs, and journey to Berkshire and reveal the strategies managers use to generate economic value from intangible values, such as thrift, integrity, entrepreneurship, autonomy, and a sense of permanence. Rich with lessons for those wishing to profit from the Berkshire model, this engaging book is a valuable read for entrepreneurs, business owners, managers, and investors, and it makes an important resource for scholars of corporate stewardship. General readers will enjoy learning how an iconoclastic businessman transformed a struggling shirt company into a corporate fortress destined to be his lasting legacy.
