The Company believes its net deferred tax asset is recoverable as of December 31, 2019 based on the expectation of future taxable income and other relevant considerations.

Pursuant to ASC 740-10-30-2 Income Taxes, deferred tax assets and liabilities are measured using enacted tax rates applicable to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.  On December 22, 2017, the President of the United States signed the “Act to provide for reconciliation pursuant to titles II and V of the concurrent resolution on the budget for fiscal year 2018” (referred to as the “Tax Cuts and Jobs Act” or the Act).  The Act provided for a reduction in the corporate tax rate from a maximum tax rate of 35% to a flat tax rate of 21% effective for tax years beginning after December 31, 2017.  As a result, the Company revalued its deferred tax assets and liabilities as of December 31, 2017, and recorded the effect of this change as a component of tax expense.  Tax expense recorded related to the change in the enacted federal tax rate was $3,108,000 in 2017.
