Note 9: Income Taxes

The effective income tax rate for the first nine months of 2013 was 24.4% as compared to 19.9% for the first nine months of 2012.  The increase in the tax rate was mainly due to recognition of various foreign taxes and an increase in certain foreign valuation allowances, largely arising as a result of the formation of OneSubsea.
