Note 3. Income Taxes

We recorded an income tax provision of $118,000 and $353,000 for the three and nine months ended September 30, 2012 and $264,000 and $295,000 for the three and nine months ended September 30, 2011, respectively. The provision for income taxes includes estimates of current taxes due in domestic and foreign jurisdictions. This provision reflects tax expense associated with state income tax, foreign taxes, and tax expense related to the recording of a deferred tax liability that results from the amortization of acquisition-related goodwill for income tax purposes.

Goodwill recorded as part of an asset purchase agreement is deductible for tax purposes and only recorded as a book charge if it is impaired. A deferred tax liability is recorded as the tax deduction is realized, which will not be reversed unless and until the goodwill is disposed of or impaired. We will continue to record an income tax expense related to the amortization of goodwill as a discrete item each quarter unless and until such impairment occurs.

As of September 30, 2012, our deferred tax assets are fully offset by a valuation allowance except in those jurisdictions where it is determined that a valuation allowance is not required. ASC 740, Income Taxes, provides for the recognition of deferred tax assets if realization of such assets is more likely than not. Based upon the weight of available evidence, which includes historical operating performance, reported cumulative net losses since inception and difficulty in accurately forecasting our future results, we provided a full valuation allowance against our net U.S. deferred tax assets and a full valuation allowance against certain foreign deferred tax assets. We reassess the need for our valuation allowance on a quarterly basis. If it is later determined that a portion of the valuation allowance should be reversed it generally will be a benefit to the income tax provision.
