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 September 30, 2019 and 2018, the Company's effective tax rate was 72% and 81%, respectively. For the nine months ended September 30, 2019 and 2018, the Company's effective tax rate was 42% and 44%, respectively. The Company's effective tax rate decreased for the three and nine months ended September 30, 2019 from the corresponding three and nine months ended September 30, 2018, primarily due to the geographic mix of income from continuing operations, and foreign losses not benefited. As of September 30, 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 $469,000. The Company maintains liabilities for uncertain tax positions. At September 30, 2019, the Company had approximately $145,000 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 September 30, 2019 and December 31, 2018, the Company had approximately $204,000 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 2015 and is subject to California tax examinations for years after 2013. 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.
