(a) Net income for the fourth quarter of 2017 reflects the income tax benefit due to the release of the Company’s valuation allowance of $141.1 million against its deferred tax assets offset by a provision of $45.1 million for remeasuring the Company’s deferred tax assets for the change in tax rates enacted under the Tax Cuts and Jobs Act of 2017.
