Description of income tax rates The Company is located in a special region, which had a 15% corporate income tax rate before the new EIT Law. The new EIT Law abolished the preferential corporate income tax rate in the special region. The Company transitioned to the new 25% tax rate over a five year period which began on January 1, 2008. During 2010, the Company applied for and received a favorable tax rate of 15% for fiscal 2011 through 2013 due to its status in the PRC as a high technology enterprise. In 2013, the Company again applied for and received the same favorable tax rate for 2014 to 2016.

Description of federal corporate income tax rate The U.S. Tax Reform significantly modified the U.S. Internal Revenue Code by, among other things, reducing the statutory U.S. federal corporate income tax rate from 35% to 21% for taxable years beginning after December 31, 2017; limiting and/or eliminating many business deductions; migrating the U.S. to a territorial tax system with a one-time transition tax on a mandatory deemed repatriation of previously deferred foreign earnings of certain foreign subsidiaries; subject to certain limitations, generally eliminating U.S. corporate income tax on dividends from foreign subsidiaries; and providing for new taxes on certain foreign earnings. Taxpayers may elect to pay the one-time transition tax over eight years, or in a single lump-sum payment. The decrease in the United States federal corporate income tax rate from 34% to 21% for 2018 decreased the valuation allowance related to the U.S. net operating losses by approximately $667,000 at December 31, 2017. There was no liability at December 31, 2017 for the mandatory deemed repatriation tax.
