Significant components of the Company's deferred tax assets as of December 31, 2013 and 2012 are summarized below.

In assessing the potential realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the Company attaining future taxable income during the periods in which those temporary differences become deductible. As of December 31, 2013 and 2012, management was unable to determine if it is more likely than not that the Company’s deferred tax assets will be realized, and has therefore recorded an appropriate valuation allowance against deferred tax assets at such dates.
 
No federal tax provision has been provided for the years ended December 31, 2013 and 2012 due to the losses incurred during such periods. Reconciled below is the difference between the income tax rate computed by applying the U.S. federal statutory rate and the effective tax rate for the years ended December 31, 2013 and 2012.
