Income Tax Disclosure [Abstract]

Income Taxes

The provision for income taxes for the periods presented in the consolidated statements of operations represents minimum California franchise taxes. Income tax expense differed from the amounts computed by applying the U.S. federal income tax rate of 34% to pretax losses as a result of the following:

	Fiscal Years Ended March 31,
	2013			2012
Computed expected tax benefit		(34.0	%)		(34.0	%)
Losses not benefitted		34.0	%		34.0	%
Other		0.1	%		0.1	%
Income tax expense		0.1	%		0.1	%

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 are as follows (in thousands):

	March 31,
	2013			2012
Deferred tax assets:
Net operating loss carryovers	$	19,010		$	16,191
Basis differences in fixed assets		9			13
Accruals and reserves		8			9
Total deferred tax assets		19,027			16,213
Valuation allowance		(19,027	)		(16,213	)
Net deferred tax assets	$	-		$	-

Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Accordingly, the deferred tax assets have been fully offset by a valuation allowance. The valuation allowance increased by $2,814,000 and $2,991,000 during the fiscal years ended March 31, 2013 and 2012, respectively. When realized, deferred tax assets related to employee stock options will be credited to additional paid-in capital.

As of March 31, 2013, the Company had U.S. federal net operating loss carryforwards of $47.9 million, which will expire in fiscal years 2019 through 2033.  As of March 31, 2013, the Company had state net operating loss carryforwards of $34.8 million, which will expire in fiscal years 2013 through 2033.

U.S. federal and state tax laws include substantial restrictions on the utilization of net operating loss carryforwards in the event of an ownership change of a corporation. The Company has not performed a change in ownership analysis since its inception in 1998 and accordingly some or all of its net operating loss carryforwards may not be available to offset future taxable income, if any. Even if the loss carryforwards are available they may be subject to substantial annual limitations resulting from past ownership changes, and ownership changes occurring after March 31, 2013, that could result in the expiration of the loss carryforwards before they are utilized.

The Company files income tax returns in the U.S. federal and Canadian jurisdictions and California and Maryland state jurisdictions. The Company is subject to U.S. federal and state income tax examinations by tax authorities for tax years 1999 through 2013 due to net operating losses that are being carried forward for tax purposes.

The Company does not have any uncertain tax positions or unrecognized tax benefits at March 31, 2013 and 2012. The Company’s policy is to recognize interest and penalties related to income taxes as components of interest expense and other expense, respectively.
