Income Tax Disclosure [Abstract]
Income taxes	7. Income taxes The Company is subject to federal and state income taxes in the United States. The tax provision for interim periods is determined using an estimate of the Company’s annual effective tax rate. The Company updates its estimated annual effective tax rate on a quarterly basis and, if the estimate changes, makes a cumulative adjustment. The Company recorded a full valuation allowance against net deferred tax assets as of June 30, 2018 and December 31, 2017 and intends to continue maintaining a full valuation allowance on these net deferred tax assets until there is sufficient evidence to support the reversal of all or some portion of these allowances. Based on current income (loss) from continuing operations and anticipated future earnings, the Company believes that there is a reasonable possibility that within the next 12 months sufficient positive evidence may become available to allow a conclusion to be reached that a significant portion, if not all, of the valuation allowance will no longer be needed. Release of some or all of the valuation allowance would result in the recognition of certain deferred tax assets and an increase in deferred tax benefit for the period any such release may be recorded, however, the exact timing and amount of any valuation allowance release are subject to change, depending upon the level of profitability that the Company is able to achieve and the net deferred tax assets available. The Company’s effective income tax rate differed from the statutory federal income tax rate of 21% for the three and six months ended June 30, 2018 and 34% for the three and six months ended June 30, 2017. For the three and six months ended June 30, 2018 and 2017, the Company’s effective income tax rate was 0%, with such differences resulting from the full valuation allowance applied against the Company’s deferred tax assets. December 22, 2017, the United States enacted tax reform legislation through the Tax Cuts and Jobs Act, which significantly changed the pre-existing U.S. tax laws. The Tax Act includes a reduction in the U.S. corporate tax rate from 34% to 21%, among other changes. In response to the Tax Act, the SEC staff issued Staff Accounting Bulletin No. 118, which allows registrants to record provisional amounts during a measurement period, not to extend beyond one year. Pursuant to SAB 118, the Company will complete the accounting for the tax effects of all of the provisions of the Tax Act within the required measurement period, not to extend beyond one year from the enactment date. As a result of the full valuation allowance at June 30, 2018 and December 31, 2017, the Tax Act did not have any material impact on the Company’s condensed consolidated financial statements. There have been no changes in estimates or additional guidance issued during the six months ended June 30, 2018 which would change the Company’s assessment of the tax impacts recorded as of the year ended December 31, 2017. The Company is still analyzing both the Federal and state impacts of the Tax Act, as additional future guidance is issued and newly obtained information is made available. Any revisions to the initial estimates will be applied in accordance with the measurement period guidance as outlined in SAB 118. The Company assesses its income tax positions and records tax benefits for all years subject to examination based upon its evaluation of the facts, circumstances and information available at the reporting dates. For those tax positions where it is more-likely-than-not that a tax benefit will be sustained, the Company has recorded the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more-likely-than-not that a tax benefit will be sustained, no tax benefit has been recognized in the Company’s financial statements. The balance of unrecognized tax benefits as of June 30, 2018 and December 31, 2017 was $1,079 and $1,134, respectively. The decrease in the balance since year-end is due to a decrease in the Company’s effective state tax rate for the year as a result of the Spin-off of red violet, which reduced the Company’s state tax footprint. In the Company’s tax return filed for the year ended December 31, 2015, a loss of $4,375, resulting from the disposal of all assets and liabilities related to the Company’s former Chinese and British Virgin Islands based subsidiaries was included for that fiscal year. This uncertain tax position is reflected as a reduction in deferred tax assets. Based on management’s assessment, no tax benefit has been recognized for this loss. This unrecognized tax benefit, if recognized, would favorably affect the Company’s annual effective tax rate before application of any valuation allowance. The Company has not accrued any interest or penalties as of June 30, 2018 with respect to its uncertain tax positions. The Company does not anticipate a significant increase or reduction in unrecognized tax benefits within the next twelve months.

7. Income taxes

The Company is subject to federal and state income taxes in the United States. The tax provision for interim periods is determined using an estimate of the Company’s annual effective tax rate. The Company updates its estimated annual effective tax rate on a quarterly basis and, if the estimate changes, makes a cumulative adjustment.

The Company recorded a full valuation allowance against net deferred tax assets as of June 30, 2018 and December 31, 2017 and intends to continue maintaining a full valuation allowance on these net deferred tax assets until there is sufficient evidence to support the reversal of all or some portion of these allowances. Based on current income (loss) from continuing operations and anticipated future earnings, the Company believes that there is a reasonable possibility that within the next 12 months sufficient positive evidence may become available to allow a conclusion to be reached that a significant portion, if not all, of the valuation allowance will no longer be needed. Release of some or all of the valuation allowance would result in the recognition of certain deferred tax assets and an increase in deferred tax benefit for the period any such release may be recorded, however, the exact timing and amount of any valuation allowance release are subject to change, depending upon the level of profitability that the Company is able to achieve and the net deferred tax assets available.

The Company’s effective income tax rate differed from the statutory federal income tax rate of 21% for the three and six months ended June 30, 2018 and 34% for the three and six months ended June 30, 2017.

The balance of unrecognized tax benefits as of June 30, 2018 and December 31, 2017 was $1,079 and $1,134, respectively.
