Income Tax Disclosure [Abstract] |
Income Taxes | Note 8. Income Taxes The Company calculates its interim income tax provision in accordance with ASC 270, “Interim Reporting,” and ASC 740 “Accounting for Income Taxes” (together, “ASC 740”). At the end of each interim period, the Company estimates the annual effective tax rate for foreign operations and applies that rate to its ordinary foreign quarterly earnings. For the Company's U.S. operations, the Company uses the discrete method to calculate the U.S. interim tax expense as the annual effective rate is not considered a reliable estimate of year-to-date income tax expense. Under the discrete method, the Company determines its U.S. tax expense based upon actual results as if the interim period were an annual period. The Company's full U.S. valuation allowance position and the seasonality of the Company's business create results with significant variations in the customary relationship between income tax expense and pre-tax income for the interim periods. As a result, the Company believes that using the discrete method is more appropriate than the annual effective tax rate method to calculate the income tax provision related to its U.S. operations. The realization of deferred tax assets, including loss and credit carry forwards, is subject to the Company generating sufficient taxable income during the periods in which the deferred tax assets become realizable. Due to the Company's cumulative pre-tax operating losses generated in the United States from 2009 to 2014, the Company recorded a valuation allowance against its U.S. deferred tax assets. As of June 30, 2016, the valuation allowance against the U.S. deferred tax assets was $164,616,000. So long as the valuation allowance exists, U.S. income tax expense related to deferred tax assets will be offset by the associated valuation allowance, resulting in an effective U.S. income tax rate on a consolidated basis substantially less than statutory rates. Once the Company demonstrates sufficient positive evidence that it is more likely than not that the Company will be able to realize its deferred tax assets, the valuation allowance would be reversed. Such evidence includes a sustained return to profitability in the U.S. business. The Company’s U.S. business was profitable in 2015 and the first half of 2016. If this trend continues, the Company would be able to reverse all or a significant portion of the valuation allowance. If the Company were to reverse the valuation allowance, the Company would realize a significant one-time, non-cash tax benefit in the period of reversal. Prospectively, the Company would then report an effective U.S. income tax rate on a consolidated basis that is closer to its statutory rates. The provision for income taxes is primarily comprised of taxes related to the Company's foreign operations. The income tax provision for the three months ended June 30, 2016 and 2015 was $1,937,000 and $1,817,000, respectively. The increase in the income tax provision was primarily due to the release of certain unrecognized tax benefits due to the lapse of statutes of limitation in various jurisdictions in the second quarter of 2015. The income tax provision for the six months ended June 30, 2016 and 2015 was $3,338,000 and $3,455,000, respectively. The decrease in the income tax provision was primarily due to the decrease in income taxes in foreign jurisdictions in the first six months of 2016. At June 30, 2016, the gross liability for income taxes associated with uncertain tax positions was $7,322,000. Of this amount, $903,000 would benefit the Company’s consolidated condensed financial statements and effective income tax rate, if favorably settled. The unrecognized tax benefit liabilities are expected to decrease by approximately $184,000 during the next 12 months. The gross liability for uncertain tax positions increased by $261,000 and $232,000 for the three and six months ended June 30, 2016, respectively. The increases were primarily due to increases in tax positions taken in the current year. The Company recognizes interest and penalties related to income tax matters in income tax expense. For the three months ended June 30, 2016 and 2015, the Company's provision for income taxes includes an expense of $54,000 and a benefit of $10,000, related to the recognition and reversal of interest and penalties, respectively. For the six months ended June 30, 2016 and 2015, the Company's provision for income taxes includes an expense of $29,000 and a benefit of $35,000 related to the recognition and reversal of interest and penalties, respectively. As of June 30, 2016 and December 31, 2015, the gross amount of accrued interest and penalties included in income taxes payable in the accompanying consolidated condensed balance sheets was $1,089,000 and $1,060,000, respectively. The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. The Company is generally no longer subject to income tax examinations by tax authorities in the following major jurisdictions:
Tax Jurisdiction |  | Years No Longer Subject to Audit
U.S. federal |  | 2010 and prior
California (United States) |  | 2008 and prior
Canada |  | 2009 and prior
Japan |  | 2009 and prior
South Korea |  | 2011 and prior
United Kingdom |  | 2011 and prior
Pursuant to Section 382 of the Internal Revenue Code, use of the Company's net operating losses and credit carry-forwards may be limited significantly if the Company were to experience a cumulative change in ownership of the Company's stock by “5-percent shareholders” that exceeds 50% over a rolling three-year period. The Company does not believe there has been a cumulative change in ownership in excess of 50% during that period. The Company continues to monitor changes in ownership. If such a cumulative change did occur in any three-year period and the Company were limited in the amount of losses it could use to offset taxable income, the Company's results of operations and cash flows could be adversely impacted.
