Buffetts förslag till Gates: En ring för 370 miljoner

Warren Edward Buffett (; born August 30, 1930) is an American business magnate, investor, and philanthropist, who is the chairman and CEO of Berkshire Hathaway. He is considered one of the most successful investors in the world and has a net worth of US$86 billion as of December 2019, making him the fourth-wealthiest person in the world.Buffett was born in Omaha, Nebraska. He developed an interest in business and investing in his youth, eventually entering the Wharton School of the University of Pennsylvania in 1947 before transferring and graduating from the University of Nebraska at the age of 19. He went on to graduate from Columbia Business School, where he molded his investment philosophy around the concept of value investing that was pioneered by Benjamin Graham. He attended New York Institute of Finance to focus his economics background and soon after began various business partnerships, including one with Graham. He created Buffett Partnership, Ltd in 1956 and his firm eventually acquired a textile manufacturing firm called Berkshire Hathaway, assuming its name to create a diversified holding company. In 1978, Charlie Munger joined Buffett and became vice chairman of the company.Buffett has been the chairman and largest shareholder of Berkshire Hathaway since 1970. He has been referred to as the "Oracle" or "Sage" of Omaha by global media outlets. He is noted for his adherence to value investing and for his personal frugality despite his immense wealth. Research published at the University of Oxford characterizes Buffett's investment methodology as falling within "founder centrism" – defined by a deference to managers with a founder's mindset, an ethical disposition towards the shareholder collective, and an intense focus on exponential value creation. Essentially, Buffett's concentrated investments shelter managers from the short-term pressures of the market.Buffett is a notable philanthropist, having pledged to give away 99 percent of his fortune to philanthropic causes, primarily via the Bill & Melinda Gates Foundation. He founded The Giving Pledge in 2009 with Bill Gates, whereby billionaires pledge to give away at least half of their fortunes. He endorsed Democratic candidate Hillary Clinton in the 2016 U.S. presidential election and will judge current U.S. President Donald Trump by his results on national safety, economic growth and economic participation when deciding if he will vote for him in the 2020 U.S. presidential election.

William Henry Gates III (born October 28, 1955) is an American business magnate, software developer, investor, and philanthropist. He is best known as the co-founder of Microsoft Corporation. During his career at Microsoft, Gates held the positions of chairman, chief executive officer (CEO), president and chief software architect, while also being the largest individual shareholder until May 2014. He is one of the best-known entrepreneurs and pioneers of the microcomputer revolution of the 1970s and 1980s. Born and raised in Seattle, Washington, Gates launched Microsoft with childhood friend Paul Allen in 1975 in Albuquerque, New Mexico; it went on to become the world's largest personal computer software company. Gates led the company as chairman and CEO until stepping down as CEO in January 2000, but he remained chairman and became chief software architect. In June 2006, Gates announced that he would be transitioning to a part-time role at Microsoft and full-time work at the Bill & Melinda Gates Foundation, the private charitable foundation that he and his wife, Melinda Gates, established in 2000. He gradually transferred his duties to Ray Ozzie and Craig Mundie. He stepped down as chairman of Microsoft in February 2014 and assumed a new post as technology adviser to support the newly appointed CEO Satya Nadella.Through his tenure at Microsoft in the 1990s, Gates had been criticized for his business tactics, which have been considered anti-competitive. This opinion has been upheld by numerous court rulings.Since 1987, he has been included in the Forbes list of the world's wealthiest documented individuals. From 1995 to 2017, he held the Forbes title of the richest person in the world all but four of those years. Since October 2017, he was surpassed by Amazon founder and CEO Jeff Bezos, who had an estimated net worth of US$90.6 billion compared to Gates' net worth of US$89.9 billion at the time. As of November 9, 2019, Gates had an estimated net worth of US$107.1 billion, making him the second wealthiest person in the world, behind Bezos. On November 15, 2019, following a 48% increase in Microsoft shares, he surpassed Bezos to once again become the richest person in the world.Later in his career and since leaving day-to-day operations at Microsoft in 2008, Gates pursued a number of philanthropic endeavors. He donated large amounts of money to various charitable organizations and scientific research programs through the Bill & Melinda Gates Foundation, reported to be the world's largest private charity. In 2009, Gates and Warren Buffett founded The Giving Pledge, whereby they and other billionaires pledge to give at least half of their wealth to philanthropy. The foundation works to save lives and improve global health, and is working with Rotary International to eliminate polio.
