Vice-Chairman Greg Abel, who oversees Berkshire’s non-insurance businesses, will take over as CEO. Vice-Chairman Ajit Jain remains in charge of insurance-related businesses. Berkshire was a struggling textile business when Mr Buffett bought it. He turned it into the world’s biggest reinsurer. Its market value of $1.2 trillion plus makes it the world’s eighth-most valuable company. Insurers can generate large sums in cheap cash in terms of premiums collected, unless there are too many claims. Berkshire has consistently generated high returns by judiciously deploying that cash. Hence, Berkshire is the world’s largest value investor. Mr Buffett’s economic interest in Berkshire is worth about $168 billion, making him the world’s fifth-wealthiest individual. While the insurance business is very profitable, much of Berkshire’s market value is derived from the large portfolio of businesses it is invested in. In 2024, it was estimated that Berkshire held a listed portfolio worth around $265 billion. It also holds significant interests in many unlisted, profitable businesses and currently has a massive cash pile of $348 billion, mostly parked in United States Treasuries. Mr Buffett’s investment philosophy is fairly transparent and his sharpness in stock-picking has been disguised by the ability to couch deep insights in simple aphorisms laced with humour.
