Income Taxes

We calculate our interim period provision for, or benefit from income taxes based on our projected annual effective tax rate as adjusted for certain discrete items.

The table below shows our effective tax rates attributable to continuing operations:



	Three Months Ended June 30				Six Months Ended June 30
	2015		2014		2015		2014
Effective tax rate	46.6	%	36.0	%	36.9	%	36.9	%

Our effective tax rate normally differs from the federal statutory tax rate of 35% due to additional provision for multistate income tax obligations. Other significant items that had an impact on our effective tax rates are noted below.

Our effective tax rate for the three months ended June 30, 2015 was higher than the 35% federal statutory rate primarily due to the accelerated recognition of unamortized investment tax credits driven by the sale of solar assets at PDL. This increased our benefit from income taxes due to a pre-tax loss for the quarter. No other items had a significant impact on our effective tax rates for the three and six months ended June 30, 2015 and 2014.

During the three and six months ended June 30, 2015, there was not a significant change in our liability for unrecognized tax benefits.
