Income Taxes | Income Taxes Our consolidated effective income tax rate for the three-month and six-month periods ended June 30, 2016 was 5.8% and 12.3%, respectively. Excluding the impact of discrete tax items, our consolidated effective income tax rate for the three-month and six-month periods ended June 30, 2016 was 19.9% and 24.3%, respectively. Discrete tax items for the three-month period ended June 30, 2016 resulted primarily from the gain on debt extinguishment, income from the ENSCO DS-9 lump-sum consideration and restructuring transactions involving certain of our subsidiaries. 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. The increase in our consolidated effective tax rate, excluding discrete items, for the three-month and six-month periods ended June 30, 2016 is primarily attributable to an increase in the relative components of our estimated 2016 earnings, excluding discrete items, generated in tax jurisdictions with higher tax rates, partially offset by the impact of restructuring transactions involving certain of our subsidiaries.
