INCOME TAXES

The Company recognizes the impact of an uncertain income tax position on its income tax return at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained.

The following is a summary of the changes in the amount of unrecognized tax benefits (in thousands):



	Fiscal Year
	2013		2012
Unrecognized tax benefits at the beginning of the period	$	307	$	383
Decrease related to prior periods	—		(76		)
Increase related to prior periods	366		—
Unrecognized tax benefits	$	673	$	307

At June 30, 2013, there were no unrecognized tax benefits presented as a component of long-term liabilities in the accompanying consolidated balance sheet. At June 30, 2013, there was $0.7 million presented as a reduction of the related deferred tax asset for which there is full valuation allowance, of which $0.5 million will affect the effective tax rate if recognized. However, the portion that would be recognized as an increase to deferred tax assets may result in a corresponding increase in the valuation allowance at the time of recognition resulting in no net effect to the effective tax rate, depending upon the Company's assessment of the likelihood of realization of the tax benefits at the time they are recognized.

The Company believes it is reasonably possible that, within the next twelve months, the amount of unrecognized tax benefits may remain unchanged. The Company recognizes interest and penalties related to unrecognized tax benefits in its provision for income taxes. The Company had no material accrual for interest and penalties on its consolidated balance sheet at fiscal years ended June 30, 2013 and 2012, and recognized no interest and/or penalties in the consolidated statement of operations for the fiscal years ended June 30, 2013 and 2012.

The Company is subject to federal and state taxation in the United States and also in certain foreign tax jurisdictions. Generally, the Company's tax returns for fiscal 2010 and forward are subject to examination by the U. S. federal tax authorities and fiscal 2009 and forward are subject to examination by state tax authorities.

The Company's ability to use its net operating loss and research and development credit carryforwards may be substantially limited due to ownership change limitations that may have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended, as well as similar state provisions. The Company has not completed a study to assess whether an ownership change has occurred or whether there have been multiple ownership changes since the Company became a “loss corporation” under the definition of Section 382. Due to the existence of the valuation allowance, it is not expected that any possible limitation will have an impact on the results of operations or financial position of the Company.

Deferred income taxes reflect the net effects 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 shown below. A full valuation allowance has been recorded, as realization of such assets is uncertain. Deferred income taxes are comprised as follows (in thousands):
