Swiss bank UBS Chairman of the Board of Directors Marcel Ospel is seen on a giant screen as he addresses shareholders during the extraordinary general meeting of the bank in Basel February 27, 2008. Shareholders in UBS are set to approve a 13 billion Swiss franc ($11.94 billion) capital injection from Singapore and an unidentified Middle East investor on Wednesday but are also likely to vent their wrath at chairman Marcel Ospel over huge subprime losses. Ospel has survived at the helm of the giant Swiss bank after culling top managers over the past year as UBS chalked up $18 billion in charges after making disastrous investments in U.S. subprime mortgages.REUTERS/Christian Hartmann (SWITZERLAND)
