Income Taxes	Note 7. 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. As of June 30, 2011, the Company has accumulated a net deferred tax liability in the amount of $4.1 million which is the result of a difference in accounting for the Company’s goodwill which is amortized over 15 years for tax purposes, but not amortized 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 open tax years remain subject to examination by major tax jurisdictions, including the federal government and the Commonwealth of Massachusetts. However, since 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 carry forwards are utilized.
