Consolidated income before provision for income taxes includes non-U.S. income of approximately $12.1 million, $2.8 million and $6.5 million for the years ended December 31, 2020, 2019 and 2018, respectively. We recorded a current tax provision of $2.0 million, $0.6 million and $0.9 million for the years ended December 31, 2020, 2019 and 2018, respectively.

As of December 31, 2020, we have federal net operating loss (“NOL”) carryforwards of approximately $57.0 million, which will begin to expire in 2024. In addition, we have federal tax credit carryforwards of approximately $0.8 million, which will begin to expire in 2021. We have utilized all state net operating losses, primarily in the state of California, as of December 31, 2020.

The deferred tax assets valuation allowance as of December 31, 2020 is attributed to U.S. federal, and state deferred tax assets, which result primarily from future deductible accruals, reserves, NOL carryforwards, and tax credit carryforwards. We believe that, based on a number of factors, the available objective evidence creates sufficient uncertainty regarding the realizability of the deferred tax assets such that a full valuation allowance has been recorded. These factors include our history of losses related to domestic operations, and the lack of carryback capacity to realize deferred tax assets. The valuation allowance increased by $0.1 million and $0.2 million for the years ended December 31, 2020 and 2019, respectively, whereas the valuation allowance decreased by $2.6 million for the year ended December 31, 2018.

The China Enterprise Income Tax Law (“EIT”) imposes a single uniform income tax rate of 25% on all Chinese enterprises.  Our subsidiaries in China have qualified for a preferential 15% tax rate that is available for High and New Technology Enterprises (“HTE”).  In order to retain the preferential tax rate, we must meet certain operating conditions, satisfy certain product requirements, meet certain headcount requirements and maintain certain levels of research expenditures. We realized benefits from this 10% reduction in tax rate of $973,000, $211,000 and $764,000 for 2020, 2019 and 2018, respectively. As of December 31, 2020, the favorable tax rate is still valid for the Company and it will stay the same for next year if there is no change of the business nature. The preferential tax rate that we enjoy could be modified or discontinued altogether at any time, which could materially and adversely affect our financial condition and results of operations.

Our subsidiaries in China also qualify for reduction in their taxable income in China for research and development (“R&D”) expenditures. Government pre-approval is required to claim R&D tax benefits. Any R&D claim is then submitted with the annual corporate income tax for the taxing authorities’ approval. Historically, we didn’t record such benefit until we received the tax refund from the Chinese government. Beginning in 2019, we record the tax benefit in the year it incurs the cost rather than in the year the tax benefit is received. This will better align the costs with the tax benefit. Our consolidated subsidiaries in China have enjoyed various tax holidays since 2000. Benefits under the tax holidays vary by jurisdiction.

Utilization of the NOL and R&D credit carryforwards may be subject to a substantial annual limitation due to ownership changes that might have occurred previously or that could occur in the future, as provided by Section 382 of the Internal Revenue Code of 1986 (“Section 382”), as well as similar state provisions. Ownership changes may limit the amount of NOL and tax credit carryforwards that can be utilized to offset future taxable income and tax, respectively. In general, an ownership change, as defined by Section 382, results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50 percentage points over a three-year period. If there is a change of control, utilization of our NOL or tax credit carryforwards would be subject to an annual limitation under Section 382. Any limitation may result in expiration of a portion of the NOL or research and development credit carryforwards before utilization. Subsequent ownership changes could further impact the limitation in future years. Until a Section 382 study is completed and any limitation known, no amounts are being presented as an uncertain tax position. A full valuation allowance has been provided against our NOL carryforwards and R&D credit carryforwards and, if an adjustment is required, this adjustment would be offset by an adjustment to the valuation allowance. Thus, there would be no net impact to the consolidated balance sheets or statements of operations if an adjustment were required.

During fiscal year 2020, 2019 and 2018, the amount of gross unrecognized tax benefits remains unchanged. The total amount of unrecognized tax benefits was $14.6 million as of December 31, 2020 and 2019. The Company recognizes interest and penalties related to uncertain tax positions as part of the provision for income taxes. To date, such interest and penalties have not been material. Excluding the effects of recorded valuation allowances for deferred tax assets, $14.6 million of the unrecognized tax benefit would favorably impact the effective tax rate in future periods if recognized.

We comply with the laws, regulations, and filing requirements of all jurisdictions in which we conduct business. We regularly engage in discussions and negotiations with tax authorities regarding tax matters in various jurisdictions.

We file income tax returns in the U.S. federal, various states and foreign jurisdictions. Currently, there is no tax audit in any of the jurisdictions and we do not expect there will be any significant change to this.

On June 29, 2020, Governor Newsom signed the highly anticipated budget package for California’s fiscal year that began on July 1, 2020. As part of the budget package, Assembly Bill 85 (“AB 85”) was enacted into law. The bill contains several tax changes to help with the budget deficit. Notably, AB 85 contains two major tax changes: (1) it suspends the usage of NOLs; and (2) it limits certain business tax credits for tax years 2020, 2021, and 2022. The budget has no impact to the Company since the Company has no NOLs and business credits to utilize.

On Sunday, December 27, 2020, a new $900 billion Coronavirus relief bill was signed into law by the President. The bill includes updates to the Families First Coronavirus Act, CARES Act, the Employee Social Security Deferral and the Paycheck Protection Program. Since the Company has no taxable income, most of the acts have no direct impact or are not applicable to the Company.
