Income Tax Disclosure [Abstract]
Income Taxes	10. Income Taxes For the three months ended March 31, 2013 and 2012, the Company recorded income tax expense of $38 and $29, respectively. The income tax expense for the three months ended March 31, 2013 and 2012 relates principally to the Company’s foreign operations. The Company has evaluated the positive and negative evidence bearing upon the realizability of its U.S. net deferred tax assets. As required by the provisions of ASC 740, Income Taxes, management has determined that it is more-likely-than-not that the Company will not utilize the benefits of federal and state U.S. net deferred tax assets for financial reporting purposes. Accordingly, the net deferred tax assets are subject to a valuation allowance at March 31, 2013 and December 31, 2012. The Company has historically provided a valuation allowance against its net deferred tax assets in Japan. Based upon the level of historical income in Japan and future projections, the Company determined in the fourth quarter of 2012 that it was probable it will realize the benefits of its future deductible differences. As such, the Company released the valuation allowance related to the remaining deferred tax assets in Japan. The Company’s income tax return reporting periods since December 31, 2009 are open to income tax audit examination by the federal and state tax authorities. In addition, because the Company has net operating loss carryforwards, the Internal Revenue Service is permitted to audit earlier years and propose adjustments up to the amount of net operating losses generated in those years. There are currently no federal, state or foreign audits in progress.
