The Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”), which became law on December 22, 2017, reduced the U.S. Federal corporate tax rate from 35% to 21% for tax years beginning in 2018. The $65 million income tax benefit in 2017 included a tax benefit of approximately $184 million due to the re-measurement of the Company’s net deferred tax liabilities associated with the 2017 Tax Act and a $32 million reduction in the Company's reserve for uncertain tax positions, partially offset by current operating results.

A reconciliation of the Company’s effective income tax rate at the U.S. federal statutory rate of 21% to the actual expense was as follows:



	Year Ended December 31,
	2018		2017		2016
Federal statutory rate	21	%	35	%	35	%
State and local income taxes, net of federal tax benefits	6		4		4

Deferred income taxes result from temporary differences between the amount of assets and liabilities recognized for financial reporting and tax purposes. The components of the deferred income tax assets and liabilities, as of December 31, are as follows:



	2018			2017
Deferred income tax assets:
Net operating loss carryforwards	$	241		$	288
Tax credit carryforwards	24			35
Accrued liabilities and deferred income	92			85
Minimum pension obligations	16			16
Provision for doubtful accounts	7			8
Liability for unrecognized tax benefits	1			1
Interest rate swaps	5			2
Total deferred tax assets	386			435

Total deferred income tax assets after valuation allowance	368			422
Deferred income tax liabilities:
Depreciation and amortization	747			736
Prepaid expenses	8			2
Basis difference in investment in joint ventures	1			10
Total deferred tax liabilities	756			748
Net deferred income tax liabilities	$	(388	)	$	(326	)

Deferred tax assets and deferred tax liabilities are netted by tax jurisdiction. The net deferred income tax liability of $388 million as of December 31, 2018 is included in the accompanying Consolidated Balance Sheets with $389 million in deferred income taxes (non-current liabilities) and $1 million in other non-current assets. The net deferred income tax liability of $326 million as of December 31, 2017 is included in the accompanying Consolidated Balance Sheets with $327 million in deferred income taxes (non-current liabilities) and $1 million in other non-current assets.

As of December 31, 2018, the Company had gross federal and state net operating loss carryforwards of $855 million. The federal net operating loss carryforwards expire between 2029 and 2033 and the state net operating loss carryforwards expire between 2019 and 2033.

Accounting for Uncertainty in Income Taxes

The Company utilizes the FASB guidance for accounting for uncertainty in income taxes, which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. The Company reflects changes in its liability for unrecognized tax benefits as income tax expense in the Consolidated Statements of Operations. As of December 31, 2018, the Company’s gross liability for unrecognized tax benefits was $20 million, of which $17 million would affect the Company’s effective tax rate, if recognized. The Company does not expect that its unrecognized tax benefits will significantly change over the next 12 months.

The Company files U.S., state and foreign income tax returns in jurisdictions with varying statutes of limitations. Tax returns for the 2006 through 2018 tax years remain subject to examination by federal and certain state tax authorities. In significant foreign jurisdictions, tax returns for the 2008 through 2018 tax years generally remain subject to examination by their respective tax authorities. The Company believes that it is reasonably possible that the total amount of its unrecognized tax benefits could decrease by $1 million in certain taxing jurisdictions where the statute of limitations is set to expire within the next 12 months.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits in interest expense and operating expenses, respectively. The Company recognized a reduction of interest expense of $1 million for the year ended December 31, 2018, a reduction of interest expense of $2 million for the year ended December 31, 2017 and a reduction of interest expense of $4 million for the year ended December 31, 2016.

The rollforward of unrecognized tax benefits are summarized in the table below:



Unrecognized tax benefits—January 1, 2016	$	78
Gross increases—tax positions in prior periods	3
Reduction due to lapse of statute of limitations	(3		)
Unrecognized tax benefits—December 31, 2016	78
Gross increases—tax positions in prior periods	1
Gross decreases—tax positions in prior periods	(54		)
Reduction due to lapse of statute of limitations	(3		)
Unrecognized tax benefits—December 31, 2017	22
Reduction due to lapse of statute of limitations	(2		)

The Company is subject to income taxes in the United States and several foreign jurisdictions. Significant judgment is required in determining the worldwide provision for income taxes and recording related assets and liabilities. In the ordinary course of business, there are many transactions and calculations where the ultimate tax determination is uncertain. The Company is regularly under audit by tax authorities whereby the outcome of the audits is uncertain. The Company believes there is appropriate support for positions taken on its tax returns. The liabilities that have been recorded represent the best estimates of the probable loss on certain positions and are adequate for all open years based on an assessment of many factors including past experience and interpretations of tax law applied to the facts of each matter. However, the outcomes of tax audits are inherently uncertain.

Tax Sharing Agreement

Under the Tax Sharing Agreement with Cendant, Wyndham Worldwide and Travelport, the Company is generally responsible for 62.5% of payments made to settle claims with respect to tax periods ending on or prior to December 31, 2006 that relate to income taxes imposed on Cendant and certain of its subsidiaries, the operations (or former operations) of which were determined by Cendant not to relate specifically to the respective businesses of Realogy, Wyndham Worldwide, Avis Budget or Travelport. With respect to any remaining residual legacy Cendant tax liabilities, the Company and its former parent believe there is appropriate support for the positions taken on Cendant’s tax returns. However, tax audits and any related litigation, including disputes or litigation on the allocation of tax liabilities between parties under the Tax Sharing Agreement, could result in outcomes for the Company that are different from those reflected in the Company’s historical financial statements.
