Israel has the second-largest number of startup companies in the world after the United States, and the third-largest number of NASDAQ-listed companies after the U.S. and China. Intel and Microsoft built their first overseas research and development facilities in Israel, and other high-tech multi-national corporations, such as IBM, Google, Apple, Hewlett-Packard, Cisco Systems, Facebook and Motorola have opened research and development centres in the country. In 2007, American investor Warren Buffett's holding company Berkshire Hathaway bought an Israeli company, Iscar, its first acquisition outside the United States, for $4 billion.
