Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes We determine our income tax provision for interim periods using an estimate of our annual effective tax rate adjusted for discrete items occurring during the periods presented. The primary difference between our effective tax rate and the federal statutory rate is the full valuation allowance we have established on our federal, state and foreign net operating losses and credits. Income taxes from international operations are not material for the three months ended March 31, 2020 and 2019. On June 7, 2019, a three-judge panel from the U.S. Court of Appeals for the Ninth Circuit overturned the U.S. Tax Court's decision in Altera Corp. v. Commissioner and upheld the portion of the Treasury regulations under Section 482 of the Internal Revenue Code that requires related parties in a cost-sharing arrangement to share expenses related to share-based compensation. As a result of this decision, our gross unrecognized tax benefits increased to reflect the impact of including share-based compensation in cost-sharing arrangements. Recognizing our gross unrecognized tax benefits would not affect our effective tax rate as their recognition would be offset by the reversal of the related deferred tax assets, which are subject to a full valuation allowance. On July 22, 2019, the taxpayer filed a petition for a rehearing before the full Ninth Circuit and the request was denied on November 12, 2019. On February 10, 2020, the taxpayer filed a petition to appeal the decision to the Supreme Court. We will continue to monitor future developments and their potential effects on our condensed consolidated financial statements.
