Income Taxes
Income Taxes	(7) Income Taxes On May 19, 2012, CVR became a member of the consolidated federal tax group of American Entertainment Properties Corporation ("AEPC"), a wholly-owned subsidiary of Icahn Enterprises, and subsequently entered into a tax allocation agreement with AEPC (the "Tax Allocation Agreement"). The Tax Allocation Agreement provides that AEPC will pay all consolidated federal income taxes on behalf of the consolidated tax group. CVR is required to make payments to AEPC in an amount equal to the tax liability, if any, that it would have paid if it were to file as a consolidated group separate and apart from AEPC. As of March 31, 2013, the Company has recorded a liability of $57.2 million for federal income taxes due to AEPC under the Tax Allocation Agreement. The Company recognizes liabilities, interest and penalties for potential tax issues based on its estimate of whether, and the extent to which, additional taxes may be due as determined under ASC Topic 740—Income Taxes. As of March 31, 2013, the Company had unrecognized tax benefits of approximately $41.1 million, of which $13.1 million, if recognized, would impact the Company's effective tax rate. Unrecognized tax benefits that are not expected to be settled within the next twelve months are included in other long-term liabilities in the Condensed Consolidated Balance Sheets; unrecognized tax benefits that are expected to be settled within the next twelve months are included in income taxes payable. The Company has accrued interest of $1.1 million related to uncertain tax positions. The Company's accounting policy with respect to interest and penalties related to tax uncertainties is to classify these amounts as income taxes. CVR and its subsidiaries file U.S. federal and various state income and franchise tax returns. At March 31, 2013, the Company's tax filings are generally open to examination in the United States for the tax years ended December 31, 2009 through December 31, 2012 and in various individual states for the tax years ended December 31, 2008 through December 31, 2012. The Company's effective tax rate for the three months ended March 31, 2013 was 30.6% as compared to the Company's combined federal and state expected statutory tax rate of 39.2%. The Company's effective tax rate for the three months ended March 31, 2013 is lower than the statutory rate primarily due to the reduction of income subject to tax associated with the noncontrolling ownership interests of CVR Refining's and CVR Partners' earnings, as well as benefits for domestic production activities. The Company's effective tax rate for the three months ended March 31, 2012 was 37.8% as compared to the Company's combined federal and state expected statutory tax rate of 39.4%. The Company's effective tax rate for the three months ended March 31, 2012 was lower than the statutory rate primarily due to the reduction of income subject to tax associated with the noncontrolling ownership interest of CVR Partners' earnings, as well as benefits for domestic production activities. Prior to the Refining Partnership IPO, CVR's deferred taxes were recorded based upon each separate component of the book versus tax basis difference of CVR's assets and liabilities, including CVR Refining's assets and liabilities. Subsequent to the Refining Partnership IPO, deferred taxes related to the net book versus tax basis difference associated with the investment in CVR Refining are recorded as a noncurrent deferred tax liability.
