Note 21.
Income Taxes
 
The Company is incorporated in the Cayman Islands, a tax-free country; accordingly, pretax income generated by the group parent company is not subject to local income tax. Substantially all of the Company’s taxable income is derived from the operations in the ROC and, therefore, substantially all of the Company’s income tax expense attributable to income from continuing operations is incurred in the ROC. Other foreign subsidiary companies calculate income tax in accordance with local tax law and regulations.
 
According to the amendments to the “Income Tax Act” enacted by the office of the President of the Republic of China (Taiwan) on February 7, 2018, an increase in the statutory income tax rate from 17% to 20% and a decrease in the undistributed earning tax from 10% to 5% are effective from January 1, 2018. The 5% surtax is only to the extent such income is not distributed or set aside as legal reserve before the end of the following year. The surtax is recorded in the period the income is earned, and the reduction in the surtax liability is recognized in the period the distribution to shareholders or the setting aside of legal reserve is finalized in the following year.
 
In accordance with the ROC Statute for Upgrading Industries, Himax Taiwan’s capital increase in June 2009 as well as Himax Semiconductor’s capital increase in October 2009 related to the manufacturing of a newly designed TFT-LCD driver were approved by the government authorities for income tax exemptions as a result of investing in a newly emerging, important and strategic industry. Himax Taiwan’s capital increase in November 2009 related to the electronic parts and components manufacturing was also approved by the government authorities for income tax exemptions. The incremental income derived from selling the above new product is tax-exempt for a period of five years.

As of December 31, 2018, the Company has not provided for income taxes on undistributed earnings of approximately $605,687 thousand of its foreign subsidiaries since the Company has specific plans to reinvest these earnings indefinitely. A deferred tax liability will be recognized when the Company can no longer demonstrate that it plans to indefinitely reinvest these undistributed earnings. This amount becomes taxable when the ultimate parent company, Himax Technologies, Inc., executes other investments, share buybacks or shareholder dividends to be funded by cash distribution by its foreign subsidiaries. It is not practicable to estimate the amount of additional taxes that might be payable on such undistributed earnings because of the complexities of the hypothetical calculation.

As of December 31, 2018, the unused investment tax credits with its expiration year from 2020 to 2034 from US operations were $1,560 thousand.
 
Tax loss carryforwards is utilized in accordance with the relevant jurisdictional tax laws and regulations. Net losses from foreign subsidiaries are approved by tax authorities in respective jurisdiction to offset future taxable profits. Under ROC Income Tax Acts, the tax loss carryforward in the preceding ten years is available to be deducted from tax income for Taiwan operations. The statutory losses would be deducted for undistributed earnings tax and were not subject to expiration for Taiwan operations.
 
As of December 31, 2018, the expiration period for abovementioned unrecognized deferred tax assets of unused operating loss carryforwards for statutory tax were as follows:

(g)Assessments by the tax authorities
 
The Company’s major taxing jurisdiction is Taiwan. Except for Himax Taiwan and Imaging Taiwan, which have been examined and assessed by the ROC tax authorities through 2015, all other Taiwan subsidiaries’ income tax returns have been examined and assessed by the ROC tax authorities through 2016. The income tax returns of 2017 for all Taiwan subsidiaries are open to examination by the ROC tax authorities. Taiwanese entities are customarily examined by the tax authorities and it is possible that a future examination will result in a positive or negative adjustment to the Company's unrecognized tax benefits within the next 12 months; however, management is unable to estimate a range of the tax benefits or detriment as of December 31, 2018.
