Note 5 – Income Taxes

We utilize the asset and liability approach which requires the recognition of deferred tax assets and liabilities for the future tax consequences of events that have been recognized in our financial statements or tax returns. In estimating future tax consequences, we generally consider all expected future events other than enactments of changes in the tax law or rates. Until sufficient taxable income to offset the temporary timing differences attributable to operations and the tax deductions attributable to option, warrant and stock activities are assured, a valuation allowance equaling the total deferred tax asset is being provided.

We utilize a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than fifty percent likely of being realized upon ultimate settlement.

Certain exercises of options and warrants, and restricted stock issued for services that became unrestricted resulted in reductions to taxes currently payable and a corresponding increase to additional-paid-in-capital for prior years. In addition, certain tax benefits for option and warrant exercises totaling $6.4 million are deferred and will be credited to additional-paid-in-capital when our net operating loss carry-forward attributable to these exercises are utilized. Consequently, these net operating loss carryforward will not be available to offset our current income tax expense. As of December 31, 2012, we had net operating loss carry-forwards of approximately $37.7 million for federal purposes that will expire beginning in Fiscal 2020 through 2032. Additionally, there are net operating loss carry-forwards of $21.4 million for state purposes that will expire beginning Fiscal 2018 through 2032. Until sufficient taxable income to offset the temporary timing differences attributable to operations and the tax deductions attributable to option, warrant and stock activities are assured, we have recorded a full valuation allowance equaling the total deferred tax asset at March 31, 2013 and December 31, 2012. As of March 31, 2013 and December 31, 2012, we have no unrecognized tax benefits.

The major jurisdiction for which we file income tax returns is the United States. The Internal Revenue Service (“IRS”) has examined our tax year ended September 30, 2005 and has made no changes to the filed tax returns. The tax years 2006 and forward remain open to examination by the IRS. The tax years 2004 and forward remain open to examination by the various state taxing authorities to which we are subject.
