Income Taxes | Note 14. Income Taxes ​ We account for income taxes in accordance with ASC Topic 740, Income Taxes (“ASC 740”), which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. ASC 740 also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that a portion of the deferred tax asset will not be realized. ​ We provide for income taxes based upon the geographic composition of worldwide earnings and tax regulations governing each region, particularly China. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws, particularly in foreign countries such as China. ​ We recognize interest and penalties related to uncertain tax positions in income tax expense. Income tax expense for the three and six months ended June 30, 2023 includes no interest and penalties. As of June 30, 2023, we have no accrued interest and penalties related to uncertain tax positions. 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. Provision for income taxes for the three and six months ended June 30, 2023 was mostly related to our wholly owned China subsidiaries and our partially owned subsidiaries in China. Income taxes and certain state taxes, have been provided for our U.S. operations as most of the income in the U.S. had been fully offset by utilization of federal and state net operating loss carryforwards. ​ Under the 2017 Tax Cuts and Jobs Act (TCJA), research and experimental (“R&E”), expenditures incurred or paid for tax years beginning after December 31, 2021 will no longer be immediately deductible for tax purposes. Instead, businesses are now required to capitalize and amortize R&E expenditures over a period of five years for research conducted within the U.S. or 15 years for research conducted in a foreign jurisdiction. We capitalize the R&E expense incurred by our China subsidiaries and amortize it over 15 years. ​ On June 29, 2020, California Governor Gavin Newsom signed Assembly Bill 85 (“AB 85”) into law as part of the California 2020 Budget Act, which temporarily suspends the use of California net operating losses and imposes a cap on the amount of business incentive tax credits that companies can utilize against their net income for tax years 2020, 2021, and 2022. We analyzed the provisions of AB 85 and determined there was no impact on our provision for income taxes for the current period and will continue to evaluate the impact, if any, AB 85 may have on the Company’s condensed consolidated financial statements and disclosures. ​
