Income Tax Disclosure [Abstract]
PROVISION FOR INCOME TAXES [Text Block]	PROVISION FOR INCOME TAXES: The Company accounts for income taxes under the provisions of ASC 740. Under the provisions of ASC 740, deferred tax assets and liabilities are recognized based on the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, utilizing the tax rates that are expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities and projected future taxable income. In the event that the Company determines, based on available evidence and management judgment, that all or part of the net deferred tax assets will not be realized in the future, the Company would record a valuation allowance in the period the determination is made. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with the Company's expectations could have a material impact on its results of operations and financial position. As of March 31, 2014, the Company continues to maintain a valuation allowance on capital losses for federal purposes, and on its California deferred tax assets as the Company believes that it is not more likely than not that these deferred tax assets will be fully realized. The Company also maintains a valuation allowance with respect to certain of its deferred tax assets relating to tax credits in Canada. Income tax expense includes a provision for (benefit from) federal, state and foreign taxes based on the annual estimated effective tax rate applicable to the Company and its subsidiaries, adjusted for certain discrete items which are fully recognized in the period they occur. The Company's effective tax rates for the three months ended March 31, 2014 and 2013, were 4.8% and (17.3)%, respectively. The difference between the expected statutory rate of 35% and the Company's effective tax rate for the three months ended March 31, 2014, was primarily due to the beneficial impact of the geographic distribution of the Company's world-wide earnings. The difference between the expected statutory rate of 35% and the Company's effective tax rate for the three months ended March 31, 2013, was primarily due to the beneficial impact of the geographic distribution of the Company's world-wide earnings and passage of the American Tax Relief Act of 2012 signed into law on January 2, 2013. The prior year impact of the 2012 Federal research and development tax credit benefit was recorded in the quarter ended March 31, 2013 due to the signing of the law in 2013. The Federal R&D tax credit has not been extended for 2014 as of the end of the first quarter, therefore no Federal R&D tax benefits have been recognized. If Congress extends the research tax credit there will be a favorable impact on the Company's 2014 effective income tax rate. The royalty arrangement between the Company and its foreign subsidiary concluded on October 31, 2012, resulting in a substantially lower effective tax rate for the Company in future years. As a result of the royalty arrangement ending and to ensure an additional source of U.S. cash, the Company plans to repatriate a portion of its current year offshore earnings to the U.S. for domestic operations and accordingly has provided for estimated federal and state income taxes on such earnings. For earnings accumulated as of December 31, 2013 and for the remaining portion of the current year earnings, the Company continues to permanently reinvest such amounts in its foreign jurisdictions, except to the extent there is any previously taxed income which is expected to be repatriated. If circumstances change and it becomes apparent that some or all of those undistributed earnings of the Company's offshore subsidiary will be remitted in the foreseeable future but income taxes have not been recognized, the Company will accrue income taxes attributable to that remittance. Determining the consolidated provision for (benefit from) income tax expense, income tax liabilities and deferred tax assets and liabilities involves judgment. The Company calculates and provides for income taxes in each of the tax jurisdictions in which it operates, which involves estimating current tax exposures as well as making judgments regarding the recoverability of deferred tax assets in each jurisdiction. The estimates used could differ from actual results, which may have a significant impact on operating results in future periods. In July 2013, the FASB issued a new accounting standard that requires the presentation of certain unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the Company's Condensed Consolidated Balance Sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The Company adopted this new standard on a prospective basis in the first quarter of 2014. The impact of the adoption was a reduction to long-term deferred tax assets and non current income tax payable of approximately $4.3 million.
