Income Taxes | 11. Income Taxes For the three months ended April 30, 2017, the Company’s income tax benefit was $133. For the three months ended April 30, 2016, the income tax provision was $120. Each of the benefit and provision primarily consists of the tax effects of foreign operating results and foreign withholding taxes. In determining the realizability of the net United States federal and state deferred tax assets, the Company considers numerous factors including historical profitability, estimated future taxable income, prudent and feasible tax planning strategies and the industry in which it operates. Management reassesses the realization of the deferred tax assets each reporting period, which resulted in a valuation allowance against the full amount of the Company’s United States deferred tax assets in the first quarter of fiscal year 2015. To the extent that the financial results of the United States operations improve in the future and the deferred tax assets become realizable, the Company will reduce the valuation allowance through earnings. The Company and one or more of its subsidiaries file United States federal income tax returns and tax returns in various state and foreign jurisdictions. With limited exceptions, the Company is no longer subject to federal, state, local or foreign examinations for years ending prior to January 31, 2012. However, carryforward attributes that were generated in tax years ending prior to January 31, 2013 may still be adjusted upon examination by state or local tax authorities if they either have been or will be used in a future period. Under Section 382 of the Internal Revenue Code of 1986, as amended, substantial changes in the Company’s ownership may limit the amount of net operating loss carryforwards that could be utilized annually in the future to offset its taxable income. Specifically, this limitation may arise in the event of a cumulative change in ownership of the Company of more than 50% within a three-year period. During the first quarter of fiscal year 2015, management determined that the Company had experienced an ownership change for purposes of Section 382. This ownership change resulted in annual limitations to the amount of net operating loss carryforwards that can be utilized to offset future taxable income, if any, at the federal level. The Company’s management has determined that, as of April 30, 2017, it had not experienced another ownership change for purposes of Section 382. However, future transactions in the Company’s common stock could trigger an ownership change for purposes of Section 382, which could further limit the amount of net operating loss carryforwards that could be utilized annually in the future to offset the Company’s taxable income, if any. Any such limitation, whether as the result of sales of common stock by the Company’s existing stockholders or sales of common stock by the Company, could have a material adverse effect on the Company’s results of operations in future years. During the quarter ended April 30, 2017, the Company adopted ASU 2016-09, which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes. Even though the Company had $1,199 of previously unrecognized excess tax benefits attributable to stock option exercises as of January 31, 2017, the adoption did not result in any adjustment to accumulated deficit in the current period because of the Company’s valuation allowance against the full of amount of the Company’s United States deferred tax assets. |
