Income Taxes [Abstract]

Income Taxes

NOTE 5 INCOME TAXES

We file income tax returns in the U.S., with various states and foreign jurisdictions, and are subject to tax audits in all jurisdictions for which we file tax returns. Tax audits by their very nature are often complex and can require several years to complete. As of June 30, 2012, we recorded a valuation allowance against all of our deferred tax assets.

Significant judgment is required in evaluating our tax positions and determining our provision for income taxes. We establish accruals for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These accruals are established when we believe that certain positions might be challenged despite our belief that our tax return positions are fully supportable. We adjust these accruals in light of changing facts and circumstances, such as the outcome of a tax audit.

Under the tax statute of limitations applicable to the Internal Revenue Code, we are no longer subject to U.S. federal income tax examinations by the Internal Revenue Service for years before 2005. However, because we are carrying forward income tax attributes, such as net operating losses and tax credits from 2002 and earlier tax years, these attributes can still be audited when used on returns filed in the future. Under the statutes of limitation applicable to most state income tax laws, we are no longer subject to state income tax examinations by tax authorities for years before 2005 in states in which we have filed income tax returns. Certain states may take the position that we are subject to income tax in such states even though we have not filed income tax returns in such states and, depending on the varying state income tax statutes and administrative practices, the statute of limitations in such states may extend to years before 2005. We are subject to foreign tax examinations by tax authorities for all years of operation.
