(See Note 3) Date Lowest price Highest price Nov 18th 2005 99.679 99.679 Notes 3 The definition of stabilisation includes both purchases and offers to purchase. Therefore, it is possible that stabilisation occurs but no stabilisation transactions are carried out. 4 The prices stated should be absolute prices e.g. expressed as a percentage of nominal value. 5 The references in article 9(3)(d) to stabilisation transactions suggests that the announcement need only include information with respect to transactions actually carried out. Additional information may be necessary if the stabilising managers undertook stabilisation transactions in any associated instruments.
