Income Taxes	Note 8. Income Taxes Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to tax benefit carryforwards and to differences between the financial statement amounts of assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates. A valuation reserve is established if it is more likely than not that all or a portion of the deferred tax asset will not be realized. The tax benefit associated with the stock option compensation deductions will be credited to equity when realized. The Company regularly assesses its ability to realize its deferred tax assets. Assessments of the realization of deferred tax assets require that management consider all available evidence, both positive and negative, and make significant judgments about many factors, including the amount and likelihood of future taxable income. Based on the available evidence and uncertainties surrounding the Company’s ability to continue to generate future taxable income, the Company has recorded valuation allowances to reduce its deferred tax assets to the amount that is more likely than not to be realizable as of September 30, 2012 and March 31, 2012. As of September 30, 2012, the Company has accumulated a net deferred tax liability of $5.1 million which is the result of the difference in accounting for the Company’s goodwill, which is amortizable over 15 years for tax purposes but not amortizable for book purposes. The net deferred tax liability cannot be offset against the Company’s deferred tax assets since it relates to an indefinite-lived asset and is not anticipated to reverse in the same period. The Company and its subsidiaries are subject to U.S. federal income tax, as well as income tax of multiple state and foreign jurisdictions. The Company has accumulated significant losses since its inception in 1981. All tax years remain subject to examination by major tax jurisdictions, including the federal government and the Commonwealth of Massachusetts. However, because the Company has net operating loss and tax credit carryforwards which may be utilized in future years to offset taxable income, those years may also be subject to review by relevant taxing authorities if the carryforwards are utilized.
