Income Taxes [Abstract]
Income Taxes	Note 2. Income Taxes We recorded an income tax provision (benefit) of $(36,000) and $57,000 for the three and nine months ended September 30, 2017, respectively. We recorded an income tax provision of $44,000 and $132,000 for the three and nine months ended September 30, 2016, respectively. The provision (benefit) for income taxes is comprised of estimates of current taxes due in domestic and foreign jurisdictions as well as changes in tax reserves. This provision (benefit) reflects tax expense associated with state income tax and foreign taxes as well as a release of a tax reserve. As of September 30, 2017, 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. During Q1 2016, ASC 740-10 reserves and related interest were released in the amount of $284,000 due to the expiration of statutes which resulted in a tax benefit to discontinued operations. The Company anticipates a material change of $134,000 in the total amount of its unrecognized tax benefits within 12 months of September 30, 2017. The change is expected to result from a refund of all withholding taxes and interest paid to the Canadian Revenue Agency (CRA) relating to an intercompany receivable that had existed on our Canadian subsidiary's books but was subsequently repaid. The refund is expected once CRA has processed the Company's previously submitted voluntary disclosure.

Note 2. Income Taxes

We recorded an income tax provision (benefit) of $(36,000) and $57,000 for the three and nine months ended September 30, 2017, respectively. We recorded an income tax provision of $44,000 and $132,000 for the three and nine months ended September 30, 2016, respectively. The provision (benefit) for income taxes is comprised of estimates of current taxes due in domestic and foreign jurisdictions as well as changes in tax reserves. This provision (benefit) reflects tax expense associated with state income tax and foreign taxes as well as a release of a tax reserve.

As of September 30, 2017, 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.

During Q1 2016, ASC 740-10 reserves and related interest were released in the amount of $284,000 due to the expiration of statutes which resulted in a tax benefit to discontinued operations.

The Company anticipates a material change of $134,000 in the total amount of its unrecognized tax benefits within 12 months of September 30, 2017.
