Effective and Statutory Rate Reconciliation — The following table summarizes a reconciliation of the U.S. statutory federal income tax rate to the Company's effective tax rate, as a percentage of income from continuing operations before taxes for the periods indicated:



December 31,	2015		2014		2013
Statutory Federal tax rate	35	%	35	%	35	%
State taxes, net of Federal tax benefit	(5	)%	(1	)%	(3	)%
Taxes on foreign earnings	3	%	(14	)%	(4	)%
Valuation allowance	(5	)%	(1	)%	—	%
Uncertain tax positions	—	%	—	%	(5	)%
Bad debt deduction	—	%	—	%	(3	)%
Change in tax law	—	%	4	%	(1	)%
Goodwill impairment	10	%	4	%	12	%
Other—net	3	%	—	%	2	%
Effective tax rate	41	%	27	%	33	%

Included in the favorable (14)% 2014 taxes on foreign earnings percentage above is approximately (8)% related to the sale of approximately 45% of the Company's interest in Masin AES Pte Ltd., which owns the Company's interests in the Philippines, and the sale of the Company's interests in four U.K. wind projects. Neither of these transactions gave rise to income tax expense.

Income Tax Receivables and Payables — The current income taxes receivable and payable are included in Other Current Assets and Accrued and Other Liabilities, respectively, on the accompanying Consolidated Balance Sheets. The noncurrent income taxes receivable and payable are included in Other Noncurrent Assets and Other Noncurrent Liabilities, respectively, on the accompanying Consolidated Balance Sheets. The next table summarizes the income taxes receivable and payable in millions as of December 31, 2015 and 2014:



	2015		2014
Income taxes receivable—current	$	167	$	217
Total income taxes receivable	$	167	$	217
Income taxes payable—current	$	264	$	299
Income taxes payable—noncurrent	35		2
Total income taxes payable	$	299	$	301

Deferred Income Taxes — Deferred income taxes reflect the net tax effects of (a) temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and (b) operating loss and tax credit carryforwards. These items are stated at the enacted tax rates that are expected to be in effect when taxes are actually paid or recovered.

As of December 31, 2015, the Company had federal net operating loss carryforwards for tax purposes of approximately $3.5 billion expiring in years 2021 to 2034. Approximately $87 million of the net operating loss carryforward related to stock option deductions will be recognized in additional paid-in capital when realized. The Company also had federal general business tax credit carryforwards of approximately $18 million expiring primarily from 2021 to 2035, and federal alternative minimum tax credits of approximately $5 million that carry forward without expiration. The Company had state net operating loss carryforwards as of December 31, 2015 of approximately $8.4 billion expiring in years 2016 to 2035. As of December 31, 2015, the Company had foreign net operating loss carryforwards of approximately $3.5 billion that expire at various times beginning in 2016 and some of which carry forward without expiration, and tax credits available in foreign jurisdictions of approximately $32 million, $24 million of which expire in 2021 and $8 million of which carryforward without expiration.

Valuation allowances decreased $103 million during 2015 to $894 million at December 31, 2015. This net decrease was primarily the result of foreign exchange losses and valuation allowance releases at certain of our Brazil and Vietnam subsidiaries.

Valuation allowances decreased $93 million during 2014 to $997 million at December 31, 2014. This net decrease was primarily the result of valuation allowance activity at certain of our Brazil subsidiaries and the release of valuation allowance against U.S. capital loss carryforwards.

The Company believes that it is more likely than not that the net deferred tax assets as shown below will be realized when future taxable income is generated through the reversal of existing taxable temporary differences and income that is expected to be generated by businesses that have long-term contracts or a history of generating taxable income. The Company continues to monitor the utilization of its deferred tax asset for its U.S. consolidated net operating loss carryforward. Although management believes it is more likely than not that this deferred tax asset will be realized through generation of sufficient taxable income prior to expiration of the loss carryforwards, such realization is not assured.

The following table summarizes the deferred tax assets and liabilities in millions, as of December 31, 2015 and 2014:



	2015			2014
Differences between book and tax basis of property	$	(2,240	)	$	(2,364	)
Other taxable temporary differences	(299		)	(302		)
Total deferred tax liability	(2,539		)	(2,666		)
Operating loss carryforwards	2,206			2,224
Capital loss carryforwards	66			137
Bad debt and other book provisions	191			221
Retirement costs	149			275
Tax credit carryforwards	55			58
Other deductible temporary differences	219			363
Total gross deferred tax asset	2,886			3,278
Less: valuation allowance	(894		)	(997		)
Total net deferred tax asset	1,992			2,281
Net deferred tax (liability)	$	(547	)	$	(385	)

The Company considers undistributed earnings of certain foreign subsidiaries to be indefinitely reinvested outside of the U.S. and, accordingly, no U.S. deferred taxes have been recorded with respect to such earnings in accordance with the relevant accounting guidance for income taxes. Should the earnings be remitted as dividends, the Company may be subject to additional U.S. taxes, net of allowable foreign tax credits. It is not practicable to estimate the amount of any additional taxes which may be payable on the undistributed earnings.

Income from operations in certain countries is subject to reduced tax rates as a result of satisfying specific commitments regarding employment and capital investment. The Company's income tax benefits related to the tax status of these operations are estimated to be $21 million, $38 million and $70 million for the years ended December 31, 2015, 2014 and 2013, respectively. The per share effect of these benefits after noncontrolling interests was $0.02, $0.04 and $0.09 for the years ended December 31, 2015, 2014 and 2013, respectively.

The Company's business in Vietnam began commercial operations in 2015. As part of its power purchase contract with the Vietnam government, the business will be subject to the following reduced income tax rates: 0% for four years, followed by 5% for nine years, followed by 10% for the remaining life of the contract term. See Item 1.—Business—Our Organization and Segments for additional information regarding the power purchase contract.

The benefit related to our operations in Vietnam is estimated to be $8 million for the year ended December 31, 2015. The per share effect of these benefits after noncontrolling interest was $0.01 for the year ended December 31, 2015.

The following table summarizes the income (loss) from continuing operations, before income taxes, net equity in earnings of affiliates and noncontrolling interests in millions, for the years ended December 31, 2015, 2014 and 2013:



	2015			2014			2013
U.S.	$	(612	)	$	(560	)	$	(575	)
Non-U.S.	1,734			2,136			1,623
Total	$	1,122		$	1,576		$	1,048

Uncertain Tax Positions — Uncertain tax positions have been classified as noncurrent income tax liabilities unless expected to be paid in one year. The Company's policy for interest and penalties related to income tax exposures is to recognize interest and penalties as a component of the provision for income taxes in the Consolidated Statements of Operations.

As of December 31, 2015 and 2014, the total amount of gross accrued income tax related interest included in the Consolidated Balance Sheets was $8 million and $14 million, respectively. The total amount of gross accrued income tax related penalties included in the Consolidated Balance Sheets as of December 31, 2015 and 2014 was $0 million and $1 million, respectively.

The total expense (benefit) for interest related to unrecognized tax benefits for the years ended December 31, 2015, 2014 and 2013 amounted to $0 million, $3 million and $(4) million, respectively. For the years ended December 31, 2015, 2014 and 2013, the total expense (benefit) for penalties related to unrecognized tax benefits amounted to $0 million, $0 million and $(3) million, respectively.

We are potentially subject to income tax audits in numerous jurisdictions in the U.S. and internationally until the applicable statute of limitations expires. Tax audits by their nature are often complex and can require several years to complete. The following is a summary of tax years potentially subject to examination in the significant tax and business jurisdictions in which we operate:



Jurisdiction		Tax Years Subject to Examination
Argentina		2009-2015
Brazil		2010-2015
Chile		2012-2015
Colombia		2013-2015
Dominican Republic		2012-2015
El Salvador		2012-2015
Netherlands		2013-2015
Philippines		2012-2015
United Kingdom		2010-2015
United States (Federal)		2011-2015

As of December 31, 2015, 2014 and 2013, the total amount of unrecognized tax benefits was $373 million, $395 million and $392 million, respectively. The total amount of unrecognized tax benefits that would benefit the effective tax rate as of December 31, 2015, 2014 and 2013 is $343 million, $366 million and $360 million, respectively, of which $24 million, $24 million and $26 million, respectively, would be in the form of tax attributes that would warrant a full valuation allowance.

The total amount of unrecognized tax benefits anticipated to result in a net decrease to unrecognized tax benefits within 12 months of December 31, 2015 is estimated to be between $15 million and $25 million, primarily relating to statute of limitation lapses and tax exam settlements.

Next is a reconciliation of the beginning and ending amounts of unrecognized tax benefits in millions for the periods indicated:



December 31,	2015			2014			2013
Balance at January 1	$	395		$	392		$	475
Additions for current year tax positions	6			8			7
Additions for tax positions of prior years	12			14			10
Reductions for tax positions of prior years	(7		)	(2		)	(3		)
Effects of foreign currency translation	(7		)	(3		)	—
Settlements	(19		)	(2		)	(65		)
Lapse of statute of limitations	(7		)	(12		)	(32		)
Balance at December 31	$	373		$	395		$	392

The Company and certain of its subsidiaries are currently under examination by the relevant taxing authorities for various tax years. The Company regularly assesses the potential outcome of these examinations in each of the taxing jurisdictions when determining the adequacy of the amount of unrecognized tax benefit recorded. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, we believe we have appropriately accrued for our uncertain tax benefits. However, audit outcomes and the timing of audit settlements and future events that would impact our previously recorded unrecognized tax benefits and the range of anticipated increases or decreases in unrecognized tax benefits are subject to significant uncertainty. It is possible that the ultimate outcome of current or future examinations may exceed our provision for current unrecognized tax benefits in amounts that could be material, but cannot be estimated as of December 31, 2015. Our effective tax rate and net income in any given future period could therefore be materially impacted.
