Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In determining the quarterly provisions for income taxes, the Company uses an estimated annual effective tax rate, which is generally based on our expected annual income and statutory tax rates in the U.S., Canada, Japan, Hong Kong, and the U.K. For the three months ended March 31, 2019 and 2018, the Company's effective tax rate was 36% and 34%, respectively. The Company's effective tax rate increased for the three months ended March 31, 2019 from the corresponding three months ended March 31, 2018, due primarily to the geographic mix of income from continuing operations, including a relative increase in foreign losses not benefited. The Tax Act created a new requirement that certain income such as Global Intangible Low-Taxed Income (“GILTI”) earned by a controlled foreign corporation (“CFC”) must be included in the gross income of the CFC U.S. shareholder. During the three months ended March 31, 2019, the Company provided for the impact in the calculation of the annual effective tax rate. The FASB Staff Q&A, Topic 740 No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election to either recognize deferred taxes for temporary differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI resulting from those items in the year the tax is incurred. We have elected to recognize the resulting tax on GILTI as a period expense in the period the tax is incurred. As of March 31, 2019, the Company is permanently reinvested in certain of its non-U.S. subsidiaries and does not have a deferred tax liability related to its undistributed foreign earnings. The estimated amount of the unrecognized deferred tax liability attributed to future withholding taxes on dividend distributions of undistributed earnings for certain non-U.S. subsidiaries, which the Company intends to reinvest the related earnings indefinitely in its operations outside the U.S., is approximately $440,000. The Company maintains liabilities for uncertain tax positions. At March 31, 2019, the Company had approximately $213,000 in total unrecognized tax benefits, which if recognized, would favorably affect the Company’s effective income tax rate. The Company’s policy is to include interest and penalties related to unrecognized tax positions in income tax expense. To the extent accrued interest and penalties do not ultimately become payable, amounts accrued will be reduced and reflected as a reduction in the overall income tax provision in the period that such determination is made. At March 31, 2019 and December 31, 2018, the Company had approximately $218,000 and $212,000 in accrued interest, respectively. The Company files income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. The Company is subject to U.S. federal and certain state tax examinations for certain years after 2013 and is subject to California tax examinations for years after 2007. The material foreign jurisdictions where the Company is subject to potential examinations by tax authorities are the France, Germany, Spain and United Kingdom for tax years after 2011. We do not know what our income taxes will be in future periods. There may be fluctuations that have a material impact on our results of operations. Our income taxes are dependent on numerous factors such as the geographic mix of our taxable income, federal and state and foreign country tax law and regulations and changes thereto, the determination of whether valuation allowances for certain tax assets are required or not, audits of prior years' tax returns resulting in adjustments, resolution of uncertain tax positions and different treatment for certain items for tax versus books. We expect fluctuations in our income taxes from year to year and from quarter to quarter. Some of the fluctuations may be significant and have a material impact on our results of operations.
