NOTE 20. - INCOME TAXES
 
The Tax Cuts and Jobs Act of 2017 (the “TCJA”) was signed into law on December 22, 2017. The TCJA includes significant changes to the U.S. corporate income tax system, including a Federal corporate rate reduction from 35% to 21%. The Company’s income tax provision (benefit) reflects the effect of this change in Federal corporate tax rates, primarily from the re-measurement of the Company’s deferred tax assets and liabilities, including prior net operating loss carry-forwards. The effect of the rate change attributable to the TCJA on the Company’s effective tax rate was a decrease of approximately 46% in the net deferred tax assets before the valuation allowance. Since the Company is in a full valuation allowance situation, the change in the Federal corporate rate had no effect on the calculation of the Company’s tax provision, which remained at zero.
 
The following is a summary of the components giving rise to the income tax provision (benefit) for the years ended December 31, 2017, 2016 and 2015:

The Company has incurred a net operating loss (“NOL”) of approximately $47,000,000 through December 31, 2017 and this amount is being carried forward to future years and begins to expire in 2031. Due to the uncertainty of the Company’s ability to generate sufficient taxable income in the future before they expire, the Company has recorded a valuation allowance to reduce the net deferred tax asset to zero. This NOL is included in the net deferred tax asset that has been fully offset by the valuation allowance. Utilization of the NOL carryforwards may be subject to an annual limitation (or the NOL’s may expire unutilized) in the case of equity ownership changes, as defined by tax law.
 
ASC 740 provides guidance on the financial statement recognition and measurement for uncertain income tax positions that are taken or expected to be taken in a company’s income tax return. The Company has no uncertain tax positions as of December 31, 2017.
