There are Research and Experimentation (“R&E”) tax credits available at both the state and local levels designed to encourage and reward companies for efforts in areas of research and experimentation. The Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010, enacted on December 17, 2010, retroactively extended the Research and Experimentation Credits which had lapsed on December 31, 2009.

As a result, the Company claimed tax credits of approximately $409,000 on its federal and state income tax returns for the year ended September 30, 2010. The Company has also filed amended federal and state income tax returns for the year ended September 30, 2009 claiming tax credits of approximately $636,000. Total Research and Experimentation Tax Credits were approximately $1,045,000. The Company uses the asset and liability approach to account for income taxes. Under this approach, deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes and net operating loss and tax credit carryforwards. The amount of deferred taxes on these temporary differences is determined using the tax rates that are expected to apply to the period when the asset is realized or the liability is settled, as applicable, based on tax rates, and tax laws, in the respective tax jurisdiction then in effect. Valuation allowances are provided if it is more likely than not that some or all of the deferred tax assets will not be realized. The provision for income taxes includes taxes currently payable, if any, plus the net change during the year in deferred tax assets and liabilities recorded by the Company. The Company applies the authoritative provisions related to accounting for uncertainty in income taxes. As required by these provisions, the Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company has applied these provisions to all tax positions for which the statute of limitations remained open. There was no impact on the Company’s consolidated financial position, results of operations, or cash flows as of June 30, 2011 and 2010. As of June 30, 2011 and 2010, the Company had no unrecognized tax benefits. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. As of June 30, 2011 and 2010, the Company had no accrued interest or penalties related to income taxes. The Company currently has no federal or state tax examinations in progress. The Company’s tax filings for federal and state jurisdictions for the years 2007 to 2010 are still subject to examination.
