The change from 2009 to 2010 is primarily due  to a change in the profitability of the countries and, to a limited  extent, due to a change in applicable statutory tax rates. The  decrease of the weighted average applicable tax rate compared  to 2009 and 2008 is mainly caused by a positive result by the  higher taxed countries compared to a negative result in 2009  and 2008 in combination with an increased share in the overall  profit of the lower taxed countries. In Canada, the federal corporate income tax rate decreased  from 19% in 2009 to 18% in 2010. The rate will further decrease  to 15% in 2012. In the United Kingdom, the corporate income  tax rate will decrease from 28% to 27% as per April 1, 2011.  In the Netherlands, the corporate income tax rate will  decrease from 25.5% to 25% as per January 1, 2011. In the  Czech Republic, the corporate income tax rate decreased from  20% in 2009 to 19% in 2010. The Hungarian corporate income  tax rate increased from 16% in 2009 to 19% in 2010. The  solidarity tax (4%) ceased to exist in 2010.  Basic earnings per share is calculated by dividing the net  income attributable to equity holders, after deduction of  preferred dividends declared, accrued coupons on perpetual  securities, coupons and premium on convertible core capital  securities and potential coupon on convertible core capital  securities by the weighted average number of common shares,  excluding common shares purchased by the Company and held  as treasury shares (refer to note 15.3). Different tax rates on overseas earnings in the reconciliation  between standard and effective income tax primarily consists of  results on intercompany reinsurance treaties between Ireland  and the United States. These reinsurance treaties are accounted  for at fair value in both tax jurisdictions and eliminated in  AEGON’s consolidated result, while losses in the United States  are deductible at 35% and gains in Ireland are taxed at 12.5%.
