• Certain stock options have been excluded from the calculation of diluted EPS because (a) their exercise prices exceeded Shire plc's average share price during the calculation period or (b) the required performance conditions were not satisfied as at the balance sheet date.
• For the three months period to March 31, 2013 the ordinary shares underlying the convertible bonds have not been included in the calculation of the diluted weighted average number of shares, as the effect of their inclusion would be anti-dilutive.
