However, in 2003, a team of American accountants—hired by Arafat's own finance ministry—began examining Arafat's finances. In its conclusions, the team claimed that part of the Palestinian leader's wealth was in a secret portfolio worth close to $1 billion, with investments in companies like a Coca-Cola bottling plant in Ramallah, a Tunisian cell phone company and venture capital funds in the U.S. and the Cayman Islands. The head of the investigation stated that "although the money for the portfolio came from public funds like Palestinian taxes, virtually none of it was used for the Palestinian people; it was all controlled by Arafat. And none of these dealings were made public." An investigation conducted by the General Accounting Office reported that Arafat and the PLO held over $10 billion in assets even at the time when he was publicly claiming bankruptcy.
