Income Taxes [Abstract]
Income Taxes	Note 3. Income Taxes We recorded an income tax provision of $149,000 and $118,000 for the three months ended March 31, 2013 and 2012, respectively. The provision for income taxes is comprised of 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 for income tax purposes of acquisition-related goodwill. When goodwill is amortizable for tax purposes, 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 part of the annual effective tax rate each quarter unless and until such disposition or impairment occurs. As of March 31, 2013, 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 partial valuation allowance against our foreign deferred tax assets. We reassess the need for our valuation allowance on a quarterly basis. If it is later determined that a portion or all of the valuation allowance is not required it generally will be a benefit to the income tax provision in the period such determination is made.

Note 3. Income Taxes

We recorded an income tax provision of $149,000 and $118,000 for the three months ended March 31, 2013 and 2012, respectively. The provision for income taxes is comprised of 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 for income tax purposes of acquisition-related goodwill.

When goodwill is amortizable for tax purposes, 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 part of the annual effective tax rate each quarter unless and until such disposition or impairment occurs.

As of March 31, 2013, 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 partial valuation allowance against our foreign deferred tax assets. We reassess the need for our valuation allowance on a quarterly basis. If it is later determined that a portion or all of the valuation allowance is not required it generally will be a benefit to the income tax provision in the period such determination is made.
