Because of the Company's lack of earnings history, the net deferred tax assets have been fully offset by a 100% valuation allowance. The valuation allowance for net deferred tax assets was $1,021,000 and $65,108,000 as of December 31, 2017 and 2016, respectively. The net change in the total valuation allowance was $(64,087,000) and $147,000 for the years ended December 31, 2017 and 2016, respectively.
 
In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment.
