Other	(13		)	(6		)
Total deferred tax liabilities	(2,213		)	(2,078		)
	$	(902	)	$	(866	)

We recorded deferred tax assets and deferred tax liabilities of $295 million and $1,197 million, respectively, as of December 31, 2015 and $389 million and $1,255 million, respectively, as of December 31, 2014. Deferred tax assets are included in other assets in our consolidated balance sheets.

We analyze all positive and negative evidence to consider whether it is more likely than not that all of the deferred tax assets will be realized. Projected future income, tax planning strategies and the expected reversal of deferred tax liabilities are considered in making this assessment. As of December 31, 2015 we had a valuation allowance of approximately $1.4 billion primarily related to tax loss and credit carryforwards, post-retirement benefits and other deferred tax assets. The current and future provisions for income taxes may be significantly impacted by changes to valuation allowances. These allowances will be maintained until it is more likely than not that the deferred tax assets will be realized. For the year ended December 31, 2015, the valuation allowance on deferred tax assets increased by $385 million. The increase was attributable to $394 million increase from the acquisition of Ferrous Resources, representing our Mining segment, and a $7 million increase recorded by American Entertainment Properties (“AEPC”), an indirect wholly owned subsidiary of ours, offset by a decrease of $16 million recorded by our Automotive segment. For the year ended December 31, 2014, the valuation allowance on deferred tax assets decreased by $157 million. The decrease was attributable to $193 million decrease recorded by our Gaming segment offset by an increase of $33 million and $3 million recorded by our Automotive segment and AEPC, respectively.

A reconciliation of the effective tax rate on continuing operations as shown in the consolidated statements of operations to the federal statutory rate is as follows:



	Year Ended December 31,
	2015		2014		2013
Federal statutory rate	35.0	%	35.0	%	35.0	%
Foreign operations	1.4		6.7		1.3
Valuation allowance	(5.5	)	21.5		(15.4	)

Automotive

Federal-Mogul did not record taxes on its undistributed earnings from foreign subsidiaries of $879 million at December 31, 2015 since these earnings are considered to be permanently reinvested. If at some future date, these earnings cease to be permanently reinvested, Federal-Mogul may be subject to U.S. income taxes and foreign withholding taxes on such amounts. Determining the unrecognized deferred tax liability on the potential distribution of these earnings is not practicable as such liability, if any, is dependent on circumstances existing when remittance occurs.

As of December 31, 2015, Federal-Mogul had $194 million of cash and cash equivalents, of which $95 million was held by foreign subsidiaries. In accordance with FASB ASC 740-30-25-17 through 19, Federal-Mogul asserts that these funds are indefinitely reinvested due to operational and investing needs of the foreign locations. Furthermore, Federal-Mogul will accrue any applicable taxes in the period when it no longer intends to indefinitely reinvest these funds. Federal-Mogul expects that the impact on cash taxes would be immaterial due to: the availability of net operation loss carryforwards and related valuation allowances; earnings considered previously taxed; and applicable tax treaties.

Federal-Mogul continues to maintain a valuation allowance related to its net deferred tax assets in multiple jurisdictions. As of December 31, 2015, our Automotive segment had valuation allowances of $801 million related to tax loss and credit carryforwards. The current and future provisions for income taxes may be significantly impacted by changes to valuation allowances in certain countries. These allowances will be maintained until it is more likely than not that the deferred tax assets will be realized. The future provision for income taxes will include no tax benefit with respect to losses incurred and no tax expense with respect to income generated in these countries until the respective valuation allowance is eliminated.

At December 31, 2015, our Automotive segment had a deferred tax asset before valuation allowance of $894 million for tax loss carryforwards and tax credits, including approximately $495 million in the United States with expiration dates from fiscal 2016 through fiscal 2035; $132 million in the United Kingdom with no expiration date; and $267 million in other jurisdictions with various expiration dates.

During 2013, IEH FM Holdings LLC, the parent company of Federal-Mogul, was contributed to American Entertainment Properties Corp. ("AEPC") in a tax-free transaction. Pursuant to the contribution and additional shares purchased, AEPC owns more than 80% of Federal-Mogul and Federal-Mogul is now included in the federal income tax consolidated group of AEPC. Positive and negative evidence was evaluated and AEPC was able to conclude that it was more likely than not to realize a portion of the Federal-Mogul deferred tax assets as part of the consolidated U.S. tax filing and released $18 million and $287 million of valuation allowance during the years ended December 31, 2014 and 2013, respectively.

Our Automotive segment has also concluded that there is a more than remote possibility that existing valuation allowances of up to $157 million as of December 31, 2015 could be released within the next 12 months. If releases of such valuation allowances occur, they may have a significant impact on our consolidated statements of operations in the quarter in which it is deemed appropriate to release the reserve.

Energy

On May 19, 2012, CVR became a member of the consolidated federal tax group of AEPC. At December 31, 2015, CVR has Oklahoma state income tax credits of approximately $26 million which are available to reduce future Oklahoma state regular income taxes. These credits have an indefinite life.

Gaming, Home Fashion, Food Packaging and Other

At December 31, 2015, AEPC, which includes all or parts of our Automotive, Energy, Railcar, Metals, Home Fashion and Real Estate segments had $1.5 billion of net operating loss carryforwards with expiration dates from years 2026 through 2035. During 2012, WPH merged into a newly formed single member limited liability company owned by AEPC. The merger constituted a tax free reorganization. Due to separate company net operating loss limitations, AEPC could not determine that it was more likely than not to realize some of the state net operating loss carryforwards and the federal net operating loss carryforward from other segments. The valuation allowance on these deferred tax assets is approximately $61 million as of December 31, 2015.

AEPC did not record taxes on its undistributed earnings from our Metals and Home Fashion segments' foreign subsidiaries of $17 million as of December 31, 2015 since these earnings are considered to be permanently reinvested. AEPC may be subject to U.S. income taxes and foreign withholding taxes on such amounts. Determining the unrecognized deferred tax liability on the potential distribution of these earnings is not practicable as such liability, if any, is dependent on circumstances existing when remittance occurs.

At December 31, 2015, Viskase had U.S. federal and state net operating loss carryforwards of $93 million which will begin expiring in the year 2024 and forward, and foreign net operating loss carryforwards of $16 million with an unlimited carryforward period. During the fourth quarter of 2013, Viskase's management determined that it was more likely than not that all of the deferred tax assets would be fully realized based on the expectation of positive evidence and projected income in future years. Accordingly, Viskase released all $55 million of its valuation allowance on deferred tax assets in 2013.

Viskase did not record taxes on its undistributed earnings from foreign subsidiaries of $66 million at December 31, 2015 since these earnings are considered to be permanently reinvested. Viskase may be subject to U.S. income taxes and foreign withholding taxes on such amounts. Determining the unrecognized deferred tax liability on the potential distribution of these earnings is not practicable as such liability, if any, is dependent on circumstances existing when remittance occurs.

ARI considers its Canadian earnings to be permanently reinvested, and therefore has not recorded a provision for U.S. income tax or foreign withholding taxes on the cumulative earnings of its Canadian subsidiary. Such undistributed earnings of $3 million from ARI's Canadian subsidiary have been included in consolidated equity as of both December 31, 2015 and 2014. If ARI were to change its intentions and such earnings were remitted to the U.S., these earnings would be subject to U.S. income taxes. However, as of December 31, 2015 and 2014 foreign tax credits would be available to offset these taxes such that the U.S. tax impact would be insignificant.

Our Gaming segment has federal NOL carryforwards pursuant to the purchase of Adamar of New Jersey, Inc. (“Adamar”). Internal Revenue Code Section 382 (“Code 382”) places certain limitations on the annual amount of NOL carryforwards that can be utilized when a change of ownership occurs. Our Gaming segment believes its purchase of Adamar was a change in ownership pursuant to Code 382. As a result of the annual limitation, the NOL carryforward amount available to be used in future periods is $156 million and will begin to expire in the year 2028 and forward. As of March 8, 2010, Tropicana had various net deferred tax assets made up primarily of the expected future tax benefit of net operating loss carryforwards and excess tax basis not yet deductible for tax purposes. A valuation allowance was provided in full against these net deferred tax assets upon emergence from bankruptcy. During the year ended December 31, 2014, our Gaming segment reversed the valuation allowance related to the net deferred tax assets by $196 million. The reduction in the valuation allowance is a result of our Gaming segment analyzing all positive and negative evidence and concluding that it is more likely than not to realize the benefit of this portion of its net deferred tax assets. The reduction in the valuation allowance was recorded as an income tax benefit during the year ended December 31, 2014.

Accounting for Uncertainty in Income Taxes

A summary of the changes in the gross amounts of unrecognized tax benefits for the fiscal years ended December 31, 2015, 2014 and 2013 are as follows:



	Years Ended December 31,
	2015			2014			2013
	(in millions)
Balance at January 1	$	113		$	132		$	113
Addition based on tax positions related to the current year	19			18			23
Increase for tax positions of prior years	6			10			6
Decrease for tax positions of prior years	(10		)	(14		)	(9		)
Decrease for statute of limitation expiration	(21		)	(3		)	(1		)
Settlements	(8		)	(25		)	1
Impact of currency translation and other	(5		)	(5		)	(1		)
Balance at December 31	$	94		$	113		$	132

At December 31, 2015, 2014 and 2013, we had unrecognized tax benefits of $94 million, $113 million and $132 million, respectively. Of these totals, $68 million, $76 million and $54 million represents the amount of unrecognized tax benefits that if recognized, would affect the annual effective tax rate in the respective periods. The total unrecognized tax benefits differ from the amount which would affect the effective tax rate primarily due to the impact of valuation allowances.

During the next 12 months, Federal-Mogul believes that it is reasonably possible that unrecognized tax benefits of Federal-Mogul may decrease by approximately $2 million due to audit settlements or statute expirations, of which approximately $1 million, if recognized, could impact the effective tax rate. We do not anticipate any significant changes to the amount of our unrecognized tax benefits in our other business segments during the next 12 months.

We recognize interest and penalties accrued related to unrecognized tax benefits as a component of income tax expense. We recorded $15 million, $19 million and $27 million as of December 31, 2015, 2014 and 2013, respectively, in liabilities for tax related net interest and penalties in our consolidated balance sheets. Income tax (benefit) expense related to interest and penalties were $(4) million, $(11) million and $8 million for the years December 31, 2015, 2014 and 2013, respectively. We or certain of our subsidiaries file income tax returns in the U.S. federal jurisdiction, various state jurisdictions and various non-U.S. jurisdictions. We and our subsidiaries are no longer subject to U.S. federal tax examinations for years before 2011 or state and local examinations for years before 2008, with limited exceptions. We, or our subsidiaries, are currently under various income tax examinations in several states and foreign jurisdictions, but are no longer subject to income tax examinations in major foreign jurisdictions for years prior to 2005.
