The domestic and international components of loss before income taxes are presented as follows:
The income tax provision (benefit) consists of the following:
The actual income tax provision (benefit) differs from the amount computed using the federal statutory rate as follows:
The components of the deferred income tax assets are as follows:
At December 31, 2020, the Company had federal, state and foreign tax net operating loss carryforwards of approximately $281.3 million, $78.7 million and $4.4 million, respectively. The federal and state tax loss carryforwards will begin to expire in 2021 and 2028, respectively, unless previously utilized. The foreign tax loss carryforwards will not expire.
At December 31, 2020, the Company had federal, state and foreign tax credit carryforwards of approximately $49.0 million, $90.1 million and $1.9 million, respectively. The federal and foreign tax credit carryforwards will begin to expire in 2023 and 2026, respectively, unless previously utilized. The state tax credit carryforwards do not expire. The Company also has foreign incentive deductions of approximately $5.8 million that do not expire.
The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the temporary differences reverse. The Company records a valuation allowance to reduce its deferred taxes to the amount it believes is more likely than not to be realized. In making such determination, the Company considers all available positive and negative evidence quarterly, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Forming a conclusion that a valuation allowance is not required is difficult when there is negative evidence such as cumulative losses in recent years. The Company believes it is more likely than not to realize certain federal and foreign deferred assets. The Company continues to maintain a valuation allowance on its state deferred taxes, certain of its federal deferred tax assets, and certain foreign deferred tax assets in jurisdictions where the Company has cumulative losses or otherwise is not expected to utilize certain tax attributes. The Company does not incur expense or benefit in certain tax-free jurisdictions in which it operates.
The income tax benefit for the year ended December 31, 2020 primarily related to the generation of research and development tax credits, mix of pre-tax income among jurisdictions, excess tax benefits related to stock-based compensation, and release of certain reserves for uncertain tax positions under ASC 740-10.
The income tax benefit for the year ended December 31, 2019 and 2018 primarily related to the mix of pre-tax income among jurisdictions, discrete tax benefits related to stock-based compensation, and release of certain reserves for uncertain tax positions under ASC 740-10.
Income tax positions must meet a more-likely-than-not threshold to be recognized. Income tax positions that previously failed to meet the more-likely-than-not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are de-recognized
in the first financial reporting period in which that threshold is no longer met. The Company records potential penalties and interest accrued related to unrecognized tax benefits within the consolidated statements of operations as income tax expense. At December 31, 2020, the Company’s unrecognized tax benefits totaled $63.8 million, $54.3 million of which, if recognized at a time when the valuation allowance no longer exists, would affect the effective tax rate. The Company does not expect its unrecognized tax benefits to change significantly over the next 12 months. At December 31, 2020 and 2019, the Company had accrued interest and penalties of approximately $0.6 million and $0.9 million, respectively. The total amounts of interest and penalties recognized for the years ended December 31, 2020, 2019, and 2018 were not material.
The following table summarizes the changes to the unrecognized tax benefits during 2020, 2019 and 2018:
The Company is subject to federal and state income tax in the United States and is also subject to income tax in certain other foreign tax jurisdictions. At December 31, 2020, the statutes of limitations for the assessment of federal, state, and foreign income taxes are closed for the years before 2017, 2016 and 2015, respectively.
In April 2017, the Company’s subsidiary in Singapore began operating under certain tax incentives in Singapore, which are generally effective through March 2022, and are conditional upon meeting certain employment and investment thresholds in Singapore. Under the incentives, qualifying income derived from certain sales of the Company’s integrated circuits is taxed at a concessionary rate over the incentive period, and there are reduced Singapore withholding taxes on certain intercompany royalties during the incentive period. Primarily because of the Company’s Singapore net operating losses and a full valuation allowance in Singapore, the incentives did not have a material impact on the Company’s income tax expense for the years ended December 31, 2020, 2019 and 2018.
