Note 9. Income Taxes
 
Deferred income taxes reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are as follows at December 31:
 
 
 
 
    2015   2014
                 
Deferred tax assets:                
Net operating loss carryforwards   $ 13,500,000     $ 13,094,000  
Depreciation     90,000       488,000  
Non-cash compensation     370,000       285,000  
Valuation Allowance     (12,339,000 )     (12,246,000 )
Deferred tax asset   $ 1,621,000     $ 1,621,000  
 
Management has reviewed its net deferred asset position, and due to the history of operating losses has determined that the application of a valuation allowance at December 31, 2015 and December 31, 2014 is warranted. If applicable, the Company would recognize interest expense and penalties related to uncertain tax positions in interest expense. As of December 31, 2015, the Company had not accrued any interest or penalties related to uncertain tax provisions.
 
The Company has net operating loss carryforwards for tax purposes of approximately $39.7 million that begin to expire in the
year 2020. Approximately $0.1 million of the total net operating loss is subject to an IRS Section 382 limitation from 1999.
