Under Swiss company law, shareholders have to approve in
a shareholders’ meeting any increase in the total number of
issued shares, which may be an ordinary share capital increase
or the creation of conditional or authorized capital.
At the annual general meeting (AGM) on 18 April 2007,
shareholders gave the Board of Directors (BoD) a mandate to
continue a repurchase program during 2007-2010 for a
maximum of 10% of the share capital (210,527,328 shares)
over the next three-year period. As part of the measures announced
in December 2007 to strengthen UBS’s capital base,
the BoD decided to rededicate the 36.4 million treasury
shares held for cancellation.
