Income Taxes [Abstract]
Income Taxes	Note 7. Income Taxes The income tax provision for interim periods is determined using an estimated annual effective tax rate adjusted for discrete items, if any, which are taken into account in the quarterly period in which they occur. We review and update our estimated annual effective tax rate each quarter. The 2018 tax rate reflects the enactment of the Tax Cuts and Jobs Act of 2017 ("Tax Act"), which permanently reduced the U.S. corporate statutory rate from 35% to 21% effective January 1, 2018. For the three and six months ended June 30, 2018 and 2017, our estimated annual effective tax rate was primarily impacted by the overall valuation allowance position which reduced the net tax impact from taxable income (loss) for all periods. Accordingly, we recorded an approximately $6,000 and $65,000 income tax provision for the three and six months ended June 30, 2018, respectively, and $139,000 and $318,000 income tax provision for the three and six months ended June 30, 2017, respectively. In 2017, in accordance with Staff Accounting Bulletin No. 118, "Income Tax Accounting Implications of the Tax Cuts and Jobs Act", we recorded provisional amounts related to the Tax Act, including the remeasurement of our deferred tax assets and liabilities and the valuation allowance related to the hanging credit deferred tax liability. We continue to evaluate the impact of the Tax Act, which may result in changes to our tax estimates. We are required to establish a valuation allowance for deferred tax assets if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Based on available evidence, realization of deferred tax assets is dependent upon the generation of future taxable income. We considered projected future taxable income, tax planning strategies, and reversal of taxable temporary differences in making this assessment. As such, we have determined that a full valuation allowance is required as of June 30, 2018 and December 31, 2017. Under the Tax Act, we will be able to use our hanging credit deferred tax liabilities as a source of taxable income to support the indefinite-lived net operating losses created by the future reversal of our temporary differences. Accordingly, we have re-measured our existing deferred tax assets and liabilities using the enacted tax rate, and adjusted the valuation allowance on our deferred taxes and, as a result, a deferred tax liability related to goodwill of $766,000 and $741,000 remains on our condensed consolidated balance sheets at June 30, 2018 and December 31, 2017, respectively. Under the provisions of ASC 740-10, we determined that there were approximately $692,000 and $677,000 of unrecognized tax benefits, including $281,000 and $266,000 of related interest and penalties, required to be recorded in other liabilities in the condensed consolidated balance sheets as of June 30, 2018 and December 31, 2017, respectively. We believe that the total amounts of unrecognized tax benefits will not significantly increase or decrease within the next 12 months.

Note 7. Income Taxes

The income tax provision for interim periods is determined using an estimated annual effective tax rate adjusted for discrete items, if any, which are taken into account in the quarterly period in which they occur. We review and update our estimated annual effective tax rate each quarter. The 2018 tax rate reflects the enactment of the Tax Cuts and Jobs Act of 2017 ("Tax Act"), which permanently reduced the U.S. corporate statutory rate from 35% to 21% effective January 1, 2018. For the three and six months ended June 30, 2018 and 2017, our estimated annual effective tax rate was primarily impacted by the overall valuation allowance position which reduced the net tax impact from taxable income (loss) for all periods. Accordingly, we recorded an approximately $6,000 and $65,000 income tax provision for the three and six months ended June 30, 2018, respectively, and $139,000 and $318,000 income tax provision for the three and six months ended June 30, 2017, respectively.

In 2017, in accordance with Staff Accounting Bulletin No. 118, "Income Tax Accounting Implications of the Tax Cuts and Jobs Act", we recorded provisional amounts related to the Tax Act, including the remeasurement of our deferred tax assets and liabilities and the valuation allowance related to the hanging credit deferred tax liability. We continue to evaluate the impact of the Tax Act, which may result in changes to our tax estimates.

We are required to establish a valuation allowance for deferred tax assets if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Based on available evidence, realization of deferred tax assets is dependent upon the generation of future taxable income. We considered projected future taxable income, tax planning strategies, and reversal of taxable temporary differences in making this assessment.
