Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company conducts operations in the United States and certain foreign countries. It is the intent of the Company to permanently reinvest any earnings and profits generated by its foreign affiliates. One of its foreign affiliates is subject to tax in Estonia. Estonia has a dual tax regime: 0% tax rate for earnings and profits as they are generated and 14% to 20% tax rates for earnings and profits that are distributed to shareholders. The Company has taken the position that the 14% to 20% tax rates apply only when dividends have been declared and recognized as a liability. Accordingly, the Company has provided no taxes on the current earnings generated by its Estonian affiliate. Income tax expense for the three months ended March 31, 2018 and March 31, 2017, is recognized based on the Company’s estimated annual effective tax rate, which is based on the tax rate expected for the full calendar year applied to the pre-tax income of the interim period adjusted for discrete items. The Company excludes from the calculation of the annual effective tax rate those jurisdictions that are projected to operate at a loss and in which a tax benefit will not be recognized or which operate in a zero tax rate jurisdiction. The Company has assessed the impacts of the changes resulting from the United States Tax Cuts and Jobs Act (U.S. TCJA) and has recognized an income tax benefit and a corresponding receivable of $0.1 million related to the recoverability of Alternative Minimum Tax Credits. Deferred tax assets, liabilities and valuation allowances have been remeasured at the new rate of 21%. Except for the recognition of the Alternative Minimum Tax Credit, there was no income impact from the remeasurement since all U.S. net deferred tax assets are fully reserved by the Company. At present, we do not estimate any material impacts from the repatriation tax. While we have completed our provisional analysis of the income tax effects of the U.S.TCJA, the related tax effects may need to be adjusted, possibly materially, due to further refinement of our calculations, changes in interpretations and assumptions that we have made, additional guidance that may be issued by regulatory bodies, and actions and related accounting policy decision we may take as a result of the new legislation. We will complete our analysis over the one-year measurement period from the enactment of the law as provided for by SAB 118, and any adjustments during this measurement period will be included in net earnings from continuing operations as an adjustment to income tax expense in the reporting period(s) when such adjustments are determined. The Company evaluates the recoverability of its net deferred tax assets based on its history of operating results, its expectations for the future and expiration dates. Based on the preponderance of the evidence, the Company has concluded that it is more likely than not it will be unable to realize the net deferred tax assets in the immediate future and has established a valuation allowance for all U.S. and foreign net deferred tax assets. At December 31, 2017, the Company’s U.S. federal net operating loss carryforwards totaled $41.7 million. The Company’s ability to use net operating loss carry forwards is subject to limitation in future periods under certain provisions of Section 382 of the Internal Revenue Code of 1986, as amended, which limit the utilization of net operating losses upon a more than 50% change in ownership of the Company’s stock that is held by 5% or greater stockholders. The Company examined the application of Section 382 with respect to an ownership change that took place during 2010, as well as the limitation on the application of net operating loss carry forwards. The Company believes that operating losses subsequent to the change date in 2010 (aggregating $23.1 million) are not subject to Section 382 limitations. The Company has estimated that the annual limitation starting in 2010 aggregates from $1.0 million to $2.3 million per year including the effect of amortization of built in gains. The Company’s loss carryforwards may be further limited in the future if additional ownership changes occur. The Company is subject to the provisions of ASC 740-10-25, “Income Taxes”. ASC 740 prescribes a more likely-than-not threshold for the financial statement recognition of uncertain tax positions. ASC 740 clarifies the accounting for income taxes by prescribing a minimum recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. On a quarterly basis, the Company undergoes a process to evaluate whether income tax accruals are in accordance with ASC 740 guidance on uncertain tax positions. For federal purposes, post 1998 tax years remain open to examination as a result of net operating loss carryforwards. The Company is currently open to audit by the appropriate state income taxing authorities for tax years 2013 to 2017. The Company has not recorded any liability for uncertain tax positions.
