For  the purpose of calculating diluted earnings per share,  AEGON assumed that all dilutive share options have been  exercised at the exercise price, or adjusted exercise price if  necessary. The proceeds are regarded as having been received  from the issue of common shares at the average market price  of the AEGON N.V. share during the year. The difference  between the number of dilutive options issued and the number  of common shares that would have been issued at the average  market price has been treated as an issue of common shares  for no consideration. The number of share options that has not been included in  the weighted average number of common shares used in the  calculation of diluted earnings per share amounted to  21,844,693 (2009: 27,090,867; 2008: 29,178,516). In 2010 and  2009, the average share price did not exceed the exercise price  and in 2008, the share options would have had an anti-dilutive  effect. At December 31, 2010, the exercise prices of these share  options range from EUR 8.93 to EUR 14.98.  The potential conversion of the convertible core capital  securities is not taken into account in the calculation of the  diluted earnings per share for the years 2009 and 2008 as this  would have an anti-dilutive effect.
