Net operating loss carryovers under Internal Revenue Code, description	The net operating loss carryovers may be subject to annual limitations under Internal Revenue Code Section 382, and similar state provisions, should there be a greater than 50% ownership change as determined under the applicable income tax regulations. The amount of the limitation would be determined based on the value of the Company immediately prior to the ownership change and subsequent ownership changes could further impact the amount of the annual limitation. An ownership change pursuant to Section 382 may have occurred in the past or could happen in the future, such that the NOLs available for utilization could be significantly limited. The Company plans to perform a Section 382 analysis in the future.

Effective for tax years, description	The Tax Act includes a participation exemption system of taxation, which generally provides for 100% dividends received deduction on certain qualifying dividend distributions received by U.S. C-corporation shareholders from their 10% or more owned foreign subsidiaries. As a result of this new participation exemption system, it is generally anticipated that the Company should not be subject to additional U.S. federal income taxation on its future receipt of actual dividend income (as opposed to a deemed inclusion amounts under certain anti-deferral rules) from its foreign subsidiary. For tax years beginning after December 31, 2017, the Tax Act introduced a new limitation on the deduction of interest expense whereby current year interest deductions are limited (among other limitations) to 30% of adjusted taxable income, with various modifications and exceptions. The Company does incur interest expense, and evaluates each year the impact, if any, of the new limitation.
