* The utilization of a portion of these net operating loss carryforwards is limited due to limits on utilizing net operating loss carryforwards under Internal Revenue Service regulations when or if a change of control were to occur (e) Taxation in the United States The Tax Cuts and Jobs Act (the “Act”) was enacted on December 22, 2017. The Act reduces the U.S. federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings. The most significant impact of the legislation for the Company was a reduction of the value of the Company’s net deferred tax assets (which represent future tax benefits) as a result of lowering the U.S. corporate income tax rate from 35% to 21%. The Act also includes a requirement to pay a one-time transition tax (the “Transition Tax”) on the cumulative value of earnings and profits that were previously not repatriated for U.S. income tax purposes. The Company does not believe that it will be required to pay any Transition Tax on its previously unrepatriated earnings and profits of its previously consolidated foreign subsidiaries. As a holding company without other business activity in Delaware, the Company is exempt from Delaware state income tax. Thus, the Company’s statutory income tax rate on domestic earnings is the federal rate of 21%.
