Income Taxes	Income Taxes Our consolidated effective income tax rate for the three-month and six-month periods ended June 30, 2015 was 17.5% and 18.4%, respectively. There were no material discrete tax items for the three-month period ended June 30, 2015. Excluding the impact of discrete income tax items for the six-month period ended June 30, 2015, our consolidated effective income tax rate was 17.5%. These discrete tax items were primarily attributable to the recognition of liabilities for unrecognized tax benefits associated with tax positions taken in prior years. Excluding the impact of the $703.5 million loss on impairment and discrete income tax expense, our consolidated effective income tax rate for the three-month and six-month periods ended June 30, 2014 was 10.4% and 10.5%, respectively. The increase in our effective tax rate, excluding discrete items, during 2015 is primarily attributable to an increase in the relative components of our estimated 2015 earnings, excluding discrete items, generated in tax jurisdictions with higher tax rates and tax legislation enacted by the U.K. government that became effective on April 1, 2014.
