Income Taxes | Income Taxes Income before provision for income taxes was as follows:
The components of provision for income taxes for all periods presented were as follows:
A reconciliation of the provision for income taxes, with the amount computed by applying the statutory Federal income tax rate to income before income taxes is as follows:
The components of deferred tax assets and liabilities were as follows:
All deferred tax assets are classified as “Other non-current assets” on the Consolidated Balance Sheets as of December 31, 2021 and December 31, 2020. In evaluating its ability to realize the net deferred tax assets, the Company considered all available positive and negative evidence, including its past operating results and the forecast of future market growth, forecasted earnings, future taxable income, and prudent and feasible tax planning strategies. As of December 31, 2021, the valuation allowance of $318 million was related to the California R&D credits and certain foreign tax attributes that the Company does not expect to realize. As of December 31, 2021, the Company's Federal R&D tax credit and state tax credit carryforwards for tax return purposes were $274 million, and $456 million, respectively. The Federal R&D tax credit carryforwards expire through 2041. State tax credit carryforwards can be carried forward indefinitely. The unrecognized tax benefits that are not expected to result in payment or receipt of cash within one year are classified as “Other non-current liabilities” and a reduction of deferred tax assets which is classified as "Other non-current assets" in the Consolidated Balance Sheets. As of December 31, 2021, the total amount of gross unrecognized tax benefits was $203 million, of which $136 million, if recognized, would favorably impact the Company’s effective tax rate. As of December 31, 2020, the total amount of gross unrecognized tax benefits was $140 million, of which $86 million, if recognized, would favorably impact the Company’s effective tax rate. The aggregate changes in the Company’s total gross amount of unrecognized tax benefits are summarized as follows (in thousands):
The Company includes interest and penalties related to unrecognized tax benefits within the provision for income taxes and in “Other non-current liabilities” in the Consolidated Balance Sheets. Interest and penalties included in the Company's provision for income taxes were not material in all the periods presented. The Company files U.S. Federal, state and foreign tax returns. The Company is currently under examination by the IRS for years 2016 through 2018 and is subject to examination for 2019 and 2020. The foreign and state tax returns for years 2015 through 2020 are subject to examination by various states and foreign jurisdictions. While the Company is in various stages of inquiries and examinations for some state and federal taxing authorities, we believe that our tax positions will more likely than not be sustained. Nonetheless, it is possible that future obligations related to these matters could arise. Given the potential outcome of the current examinations as well as the impact of the current examinations on the potential expiration of the statute of limitations, it is reasonably possible that the balance of unrecognized tax benefits could significantly change within the next twelve months. However, an estimate of the range of reasonably possible adjustments cannot be made at this time.
