The effective income tax rate for the total provision for the three months ended June 30, 2014, is greater than the federal statutory rate primarily due to taxes on foreign operations and the effect of state income taxes, partially offset by the impact of nontaxable noncontrolling interests.
The effective income tax rate for the total provision for the six months ended June 30, 2014, is less than the federal statutory rate primarily due to a tax benefit related to the completion of the Canada Dropdown in the first quarter of 2014 and the impact of nontaxable noncontrolling interests, partially offset by the effect of state income taxes and taxes on foreign operations.
The effective income tax rates for the total provision for the three and six months ended June 30, 2013, are less than the federal statutory rate primarily due to the impact of nontaxable noncontrolling interests and taxes on foreign operations, partially offset by the effect of state income taxes. The 2013 state deferred provision includes $10 million, net of federal benefit, related to the impact of a second-quarter Texas franchise tax law change.
As a result of closing the Canada Dropdown, approximately $80 million of previously deferred tax liability has been reclassified as a current income tax liability through the second quarter of 2014.
During the next 12 months, we do not expect ultimate resolution of any unrecognized tax benefit associated with domestic or international matters to have a material impact on our unrecognized tax benefit position.
