Income Tax Disclosure [Abstract]
Income Taxes	Note 15—Income Taxes 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 during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future results of operations and tax planning strategies in making this assessment. Based upon the level of historical taxable income, significant book losses during the current and prior periods and projections for future results of operations over the periods in which the deferred tax assets are deductible, among other factors, management continues to conclude that we did not meet the “more likely than not” requirement in order to recognize deferred tax assets and a valuation allowance has been recorded for the full amount of our net deferred tax assets at September 30, 2016. During the three and nine months ended September 30, 2016 and 2015, no adjustments were recognized for uncertain tax positions. Our net taxable income must be apportioned to various states based upon the income tax laws of the states in which we derive our revenue. Our net operating loss ("NOL") carryforwards will not always be available to offset taxable income apportioned to the various states. The states from which some of our revenues are derived are not the same states in which our NOLs were incurred; therefore we expect to incur state tax liabilities on the net income of our refining, logistics, retail and Texadian segments. Pursuant to ASC 740-20-45-7, we recognize the interim effects of intraperiod tax allocation discretely. As a result, during the second quarter of 2016, we recorded a benefit for the release of $8.6 million of our valuation allowance to offset future temporary differences associated with the 5.00% Convertible Senior Notes. During the nine months ended September 30, 2015, we recorded a benefit for the release of $18.3 million of our valuation allowance as we expect to be able to utilize a portion of our NOL carryforwards to offset future taxable income of PHI. Excluding the impact of releasing the tax valuation allowance in 2016 with respect to the issuance of the 5.00% Convertible Senior Notes, we recognized a state tax expense of $1 thousand and state tax benefit of $17 thousand for the three and nine months ended September 30, 2016, respectively. Excluding the impact of releasing the valuation allowance in 2015, we recognized a state tax expense of $174 thousand and $217 thousand during the three and nine months ended September 30, 2015, respectively. We will continue to assess the realizability of our deferred tax assets based on consideration of actual and projected operating results and tax planning strategies. Should actual operating results continue to improve, the amount of the deferred tax asset considered more likely than not to be realizable could be increased.

Note 15—Income Taxes

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 during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future results of operations and tax planning strategies in making this assessment. Based upon the level of historical taxable income, significant book losses during the current and prior periods and projections for future results of operations over the periods in which the deferred tax assets are deductible, among other factors, management continues to conclude that we did not meet the “more likely than not” requirement in order to recognize deferred tax assets and a valuation allowance has been recorded for the full amount of our net deferred tax assets at September 30, 2016.

During the three and nine months ended September 30, 2016 and 2015, no adjustments were recognized for uncertain tax positions.

Our net taxable income must be apportioned to various states based upon the income tax laws of the states in which we derive our revenue. Our net operating loss ("NOL") carryforwards will not always be available to offset taxable income apportioned to the various states. The states from which some of our revenues are derived are not the same states in which our NOLs were incurred; therefore we expect to incur state tax liabilities on the net income of our refining, logistics, retail and Texadian segments.

Pursuant to ASC 740-20-45-7, we recognize the interim effects of intraperiod tax allocation discretely. As a result, during the second quarter of 2016, we recorded a benefit for the release of $8.6 million of our valuation allowance to offset future temporary differences associated with the 5.00% Convertible Senior Notes.

We will continue to assess the realizability of our deferred tax assets based on consideration of actual and projected operating results and tax planning strategies. Should actual operating results continue to improve, the amount of the deferred tax asset considered more likely than not to be realizable could be increased.
