Income Tax Disclosure [Abstract] |
Income Taxes | Note 10. Income Taxes Utilization of the net operating loss carryforwards and credits may be subject to substantial annual limitation due to the ownership change limitations provided by Section 382 of the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization. We evaluate tax positions for recognition using a more-likely-than-not recognition threshold, and those tax positions eligible for recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon the effective settlement with a taxing authority that has full knowledge of all relevant information. We file tax returns in the United States for federal, California, and other states. All tax years remain open to examination for both federal and state purposes as a result of our net operating loss and credit carryforwards. We file foreign tax returns in the United Kingdom starting with the year ended January 31, 2013, in France, Germany and Japan starting with the year ended January 31, 2014, in Canada starting with the year ended January 31, 2015, and in Australia, Sweden, and Netherlands starting with the year ended January 31, 2016. These tax years remain open to examination. We believe that we have provided adequate reserves for our income tax uncertainties in all open tax years. We do not expect our gross unrecognized tax benefits to change significantly over the next 12 months.
