losses. Under certain conditions, the Dingxing local government may purchase the land and building at the appraised value. We believe that such cooperation agreements are normal, customary and usual in China and that the future valuation is flexible. We have a similar agreement with the city of Kazuo, China, although on a smaller scale. The total investment targeted by AXT in Kazuo is approximately $15 million in value, assets and capital. In addition, BoYu has a similar agreement with the city of Kazuo. The total investment targeted by BoYu in Kazuo is approximately $8 million in value, assets and capital.
Purchase Obligations with Penalties for Cancellation
In the normal course of business, we issue purchase orders to various suppliers. In certain cases, we may incur a penalty if we cancel the purchase order. As of March 31, 2024, we do not have any outstanding purchase orders that will incur a penalty if cancelled by the Company.
Legal Proceedings
From time to time we may be involved in judicial or administrative proceedings concerning matters arising in the ordinary course of business. We do not expect that any of these matters, individually or in the aggregate, will have a material adverse effect on our business, financial condition, cash flows or results of operations.
Note 13. Other Income (expense), Net
Other income (expense), net for the three months ended March 31, 2024 and 2023, includes a grant of $1.0 million and $0.5 million, respectively, from government agencies as awards for technological innovation.
In addition, we incurred a foreign currency transaction exchange gain of $58,000 and a loss of $213,000 for the three months ended March 31, 2024 and 2023, respectively.
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 months ended March 31, 2024 includes no interest and penalties. As of March 31, 2024, 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 months ended March 31, 2024 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, 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.
