Among other changes, the Act reduces the US corporate income tax rate to 21% effective January 1, 2018. Because the Act became effective mid-way through the Company&#226;&#8364;&#8482;s tax year, the Company will have a US statutory income tax rate of 27.7% for the fiscal 2018 and will have a 21% statutory income tax rate for fiscal years thereafter. Under ASC740, Accounting for Income Taxes, the enactment of the Tax Act also requires companies, to recognize the effects of changes in tax laws and rates on deferred tax assets and liabilities and the retroactive effects of changes in tax laws in the period in which the new legislation is enacted. The Company&#226;&#8364;&#8482;s gross deferred tax assets and liabilities we revalued from 35% to 21%. Deferred tax assets of $46.2 million (as of the enactment effective date) were revalued to approximately $30.2 million with a corresponding decrease to the Company&#226;&#8364;&#8482;s valuation allowance.</link:label>
