Under current Bermuda law, the Company's Bermuda domiciled subsidiaries are not required to pay any taxes in Bermuda on income or capital gains. The Company has received an assurance from the Minister of Finance in Bermuda that, in the event of any taxes being imposed, it will be exempt from taxation in Bermuda until March 2035. The Company's primary Bermuda subsidiary has an operating branch in Singapore, which is subject to the relevant taxes in that jurisdiction. The branch is not under examination in this tax jurisdiction, but remains subject to examination for tax years 2014 through 2017.

The Company's U.S. subsidiaries are subject to federal, state and local corporate income taxes and other taxes applicable to U.S. corporations. The provision for federal income taxes has been determined under the principles of the consolidated tax provisions of the U.S. Internal Revenue Code and Regulations. Should the U.S. subsidiaries pay a dividend outside the U.S. group, withholding taxes will apply. The Company's U.S. subsidiaries are not under examination but remain subject to examination in the U.S. for tax years 2014 through 2017.

In Canada, the Company's U.S. reinsurance company operates through a branch and its U.S. service company has an unlimited liability company subsidiary based in Canada. These Canadian operations are subject to the relevant taxes in that jurisdiction and remain subject to examination for tax years 2013 through 2017.

The Company also has subsidiaries in Ireland, the U.K., Belgium, the Netherlands, Luxembourg, Brazil and Dubai. In 2017, the Company ceased operations in Australia. These subsidiaries and their branches, are not under examination, but remain subject to examination in all applicable jurisdictions for tax years 2013 through 2017.

In the U.K., the Company has Lloyd’s syndicates whose income is subject to tax in the U.K. payable by its corporate members. The income from operations at Lloyd’s is also subject to taxes in other jurisdictions in which Lloyd's operates, including the U.S. Under a Closing Agreement between Lloyd’s and the IRS, Lloyd’s Members pay U.S. income tax on U.S. connected income written by Lloyd’s syndicates. To the extent that the Lloyd’s syndicates suffer taxes outside the U.K. they may claim a credit for foreign taxes suffered, limited to the U.K. equivalent tax on the same income.

On December 22, 2017, H.R.1, An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018 ("U.S. Tax Reform") was signed into law. U.S. Tax Reform, among other things, reduced the U.S. corporate income tax rate from 35% to 21% effective January 1, 2018. Consequently, the Company reduced its net deferred tax assets as of December 31, 2017 by $41.6 million which is reflected in deferred tax expense.

As a result of the Company's acquisitions of Aviabel and Novae in 2017, $103.8 million of net deferred tax liabilities were acquired or established at the acquisition date.

Total operating and capital loss carryforwards and tax credits are summarized in the following table:




At December 31,	2017		2016

Operating and Capital Loss Carryforwards⁽¹⁾
Singapore (branch) operating loss carryforward	$	77,467	$	83,532

U.S. alternative minimum tax credit	12,052		6,840
U.K. tax credit⁽³⁾	14,310		—


(1)	All operating and capital loss carryforwards and tax credits can be carried forward indefinitely with the exception of the U.S. net operating loss which will expire in 2037.


(2)	As a result of ceasing the Company's Australian operations, operating loss and capital loss carryforwards were written off.


(3)	As a result of the Company's acquisition of Novae, these amounts include $23.0 million and $14.8 million of acquired operating loss and tax credit carryforwards, respectively.

An analysis of the movement in the Company's valuation allowance is shown in the following table:




At December 31,	2017			2016

Income tax expense:
Valuation allowance - beginning of year	$	41,100		$	40,331
Operating loss carryforwards	(27,116		)	3,857
Foreign tax credit	267			(2,775		)
Australian CTA and accruals and other foreign rate differentials	1,006			(313		)
Change in investment-related items	900			—
Valuation allowance - end of year	$	16,157		$	41,100

At December 31, 2017 and 2016, the Company established a full valuation allowance on: (1) operating and capital loss carryforwards relating to operations in Australia and Singapore; (2) un-utilized foreign tax credits available in Ireland and (3) certain other deferred tax assets related to branch operations. In 2017 the valuation allowance was released on the Australian operating loss carryforwards, capital loss carryforwards, and other deferred tax assets upon the cessation of operations. The valuation allowance was reduced by a net $1.2 million for items unrelated to the Australian operations.

Although realization is not assured, management believes it is more likely than not that the tax benefit of the recorded net deferred tax assets will be realized. In evaluating the Company's ability to recover these tax assets within the jurisdiction from which they arise, it considered all available positive and negative evidence, including historical results, operating loss carry-back potential and scheduled reversals of deferred tax liabilities. The Company believes its U.S. and U.K. operations will produce significant taxable income in future periods and have deferred tax liabilities that will reverse in future periods, such that the Company believes sufficient ordinary taxable income is available to utilize all remaining ordinary deferred tax assets. In 2017 and 2016, there were sufficient net unrealized gains or capital loss carryback potential to offset remaining impairments, therefore, a valuation allowance on such impairments in the U.S. was not considered necessary.

At December 31, 2017 and 2016, there were no unrecognized tax benefits.

The following table presents the distribution of income before income taxes between domestic and foreign jurisdictions as well as a reconciliation of the actual income tax rate to the amount computed by applying the effective tax rate of 0% under Bermuda law to income before income taxes:
