	For the Years Ended December 31,
	2014		2013		2012

Income tax expense/(benefit) at U.S. federal statutory rate	35.0	%	(35.0)	%	(35.0)	%

As of December 31, 2014 and 2013, the Company had income taxes receivable of $15.0 million and $5.7 million, respectively, included in other current assets. The $15.0 million receivable at December 31, 2014, primarily includes a U.S. federal tax receivable of $14.3 million from the carry back of U.S. federal net operating losses to December 31, 2011 and 2012.

As of December 31, 2014, we have U.S. net operating loss (“NOL”) carry forwards of $139.0 million that are available to reduce future taxable income. In addition, we have $1.0 million of various U.S. tax credits available to reduce future taxable income. The U.S. NOL and tax credit carry forwards begin to expire in 2034.

As of December 31, 2014, we have state NOL carry forwards of $299.0 million that are available to reduce future taxable income. In addition, we have $2.9 million of various state tax credits available to reduce future taxable income. The state NOL and tax credit carry forwards begin to expire at various times.

As of December 31, 2014, we have Puerto Pico NOL carry forwards of $0.7 million that are available to reduce future taxable income. The Puerto Rico NOL carry forwards begin to expire in 2018.

Management has decided that a valuation allowance related to state NOL carry forwards and state tax credit carry forwards is necessary. As of December 31, 2014, the valuation allowance includes $0.1 million related to state NOL carry forwards and $0.4 million related to state tax credit carry forwards. The valuation allowance included $0.2 million related to state NOL carry forwards as of December 31, 2013. The net change in the total valuation allowance for the year ended December 31, 2014 was an increase of $0.3 million; there was no change in the total valuation allowance for the year ended December 31, 2013.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income in those jurisdictions during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carry back and carry forward periods), projected future taxable income, and tax-planning strategies in making this assessment. In order to fully realize the deferred tax assets, the Company will need to generate future taxable income before the expiration of the carry forwards governed by the tax code. Based on the current level of pretax earnings, the Company will generate the minimum amount of future taxable income to support the realization of the deferred tax assets. As a result, management believes that it is more likely than not that we will realize the benefits of these deferred tax assets, net of the existing valuation allowances at December 31, 2014. The amount of the deferred tax asset considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carry forward period are reduced.


Uncertain Tax Positions

We account for uncertain tax positions in accordance with the authoritative guidance for uncertain tax positions. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (amounts in millions):

			For the Years Ended December 31,
			2014		2013
	Balance at beginning of period		$	3.9	$	0.4
		Additions for tax positions related to current year		0.3		0
		Additions for tax positions related to prior year		0		3.5
		Reductions for tax positions related to prior years		0		0
		Lapse of statute of limitations		(0.2)		0
		Settlements		0		0
	Balance at end of period		$	4.0	$	3.9

As of December 31, 2014, there are $0.5 million and $3.5 million of unrecognized tax benefits recorded in other long-term obligations and deferred income taxes, respectively, within the consolidated balance sheet.

Included in the balance of unrecognized tax benefits at December 31, 2014 is $4.0 million of tax benefits that, if recognized in future periods, would impact our effective tax rate.

During the years ended December 31, 2014 and 2013, we recognized interest and penalties of $0.1 million and less than $0.1 million, respectively, as components of penalties or interest expense in connection with our reserve for uncertain tax positions. Interest and penalties, related to uncertain tax positions, included in the consolidated balance sheet at December 31, 2014 and 2013 were less than $0.1 million for each year.

We are subject to income taxes in the U.S. and in many of the 50 individual states, with significant operations in Louisiana, Alabama, Georgia, and Tennessee. In addition, we are subject to income taxes in Puerto Rico. We are open to examination in the U.S. and in various individual states for tax years ended December 31, 2011 through December 31, 2014. We are also open to examination in various states for the years ended 2001 – 2014 resulting from net operating losses generated and available for carry forward from those years.
