Income taxes [Abstract]

Income taxes

Note 13.  Income taxes

We use the liability method, where deferred tax assets and liabilities are determined based on expected future tax consequences of temporary differences between the carrying amounts of assets and liabilities for financial and income tax reporting purposes.  At December 31, 2012, we had approximately $10,531,971 of losses available for carry forward to future years.  The unused net operating losses begin to expire December 31, 2024.  At December 31, 2012, our deferred tax asset resulting from the cumulative net operating losses amounted to $3,686,190 which is covered by a full valuation allowance due to uncertainty of our ability to generate future taxable income necessary to realize the related deferred tax asset.
