For purposes of comparability, the Company used the notional U.S. federal income tax rate of 21% for the 2018 tax year and 35% for the 2017 and 2016 tax years when presenting the Company's reconciliation of the income tax provision. The Company is a resident taxpayer in Jersey and as such is not generally subject to Jersey tax on remitted foreign earnings. A reconciliation of the provision for income taxes compared with the amounts at the notional federal statutory rate was:

	Year ended December 31,
	2018			2017			2016
U.S statutory income taxes rate		21.0	%		35.0	%		35.0	%
Non-deductible expenses		(2.2	)		(6.8	)		(2.5	)
Foreign taxes rate differential		13.2			15.1			(14.2	)
Change in valuation allowance (1)		(62.3	)		(11.9	)		(30.0	)
State income taxes (1)		(4.5	)		18.7			2.3
Share based compensation		(4.5	)		(4.5	)		1.2
Change in unrecognized taxes expense		0.3			(0.8	)		(0.7	)
Other (1)		0.7			(71.9	)		0.4
Effective taxes rate		(38.3	)%		(27.1	)%		(8.5	)%

The Company's tax rate is affected by the tax rates in the jurisdictions outside the U.S. in which the Company operates. The jurisdictional location of earnings is a significant component of our effective tax rate as the tax rates outside of the U.S. generally differ from the U.S. tax rate of 21% for the 2018 tax year and 35% for the 2017 and 2016 tax years, and the relative amount of losses or income for which no tax benefit or expense was recognized due to a valuation allowance.

In 2017, the Tax Cuts and Jobs Act of 2017 (the “TCJA”) was signed into law in the U.S. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017. In accordance with ASC 740, the Company recorded $34.8 million of deferred tax expense in connection with the remeasurement of certain deferred tax assets and liabilities. This was fully offset by a valuation allowance. Accordingly, there was no net impact on the Company’s income tax expense for the year ended December 31, 2017. The Company’s subsidiary in the United States does not have any foreign subsidiaries and, therefore, the remaining provisions of the TCJA have no material impact on the Company's results of operations. December 22, 2018 marked the end of the measurement period for purposes of SAB 118, and the Company concluded that no change was required to its initial assessment.

	Year ended December 31, 2017

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are as follows:

	December 31,
	2018			2017
Deferred tax assets:
Allowance for doubtful accounts	$	-		$	6,797
Revenue recognition		99,316			60,099

Share based compensation		10,886			7,544
Deferred revenue		1,643			1,340

Total gross deferred taxes assets	$	114,072		$	77,899

Total deferred taxes assets	$	1,712		$	2,095
Deferred tax liabilities:
Fixed assets		1,427			1,486
Total gross deferred taxes liabilities	$	1,427		$	1,486

Net deferred taxes assets	$	285		$	609

As of December 31, 2018, the Company has $3.2 million of net operating loss carry forwards (NOLs) available for utilization in Luxembourg in future years.

A reconciliation of the beginning and ending balances of uncertain tax benefits is as follows:

	December 31,
	2018			2017		2016
Balance at beginning of the year	$	2,827		$	2,400	$	1,565
Additions (reductions) for taxes positions related current year		(141	)		55		1,088
Additions (reductions) for taxes positions related to prior years		(2,583	)		372		58
Additions (reductions) related to lapse of applicable statute of limitations		-			-		(311	)
Balance at the end of the year	$	103		$	2,827	$	2,400

The Company recognizes interest and penalties related to unrecognized tax benefits in tax expense. During the years ended December 31, 2018, 2017 and 2016, the Company accrued $2, $ 95 and $31, respectively, for interest and penalties expenses related to uncertain tax positions.

The Company's Israeli subsidiary concluded a federal income tax audit for the tax year 2013-2016. There are no other ongoing income tax audits.
