A total of 63,137 shares (2004: 70,982 shares; 2003: 110,022 shares) were subscribed and settled through a release of treasury shares, at a market value of approximately CHF 142.20 per share (2004: 117.20 per share; 2003: CHF 75.75 per share). Shares purchased under this plan vest immediately, and are subject to a three year blocking period.
