Income Tax Disclosure [Abstract] |
Income Taxes | Note 10. Income Taxes 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 believe that we have provided adequate reserves for our income tax uncertainties in all open tax years. We file tax returns in the U.S. 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 began to 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. Certain tax years remain open to examination.
