Income Taxes [Abstract]
Income Taxes	14. INCOME TAXES The Company is domiciled in the United States and has subsidiaries domiciled within the United States with significant branches in Canada and Singapore. The Company's non-U.S. branches are subject to income taxation at varying rates in their respective domiciles. The Tax Cuts and Jobs Act ("TCJA") was passed on December 22, 2017. The primary changes from TCJA affecting the Company is a reduction of the corporate income tax rate from 35% to 21% beginning January 1, 2018 as well as the imposition of a new Base Erosion and Anti-abuse Tax ("BEAT") of 5% in 2018 and 10% from 2019 – 2025 and 12.5% thereafter on certain transactions with non-US affiliates of the Company. The Company generally applies the estimated annual effective tax rate approach for calculating its tax provision for interim periods as prescribed by ASC 740-270, Interim Reporting. Under the estimated annual effective tax rate approach, the estimated annual effective tax rate is applied to the interim year-to-date pre-tax income/loss to determine the income tax expense or benefit for the year-to-date period. If the annual effective tax rate approach produces a year-to-date tax benefit which exceeds the amount which is estimated to be recoverable for the full year, then the tax benefit for the interim reporting period will be limited as prescribed under ASC 740-270 to the estimated recoverable based on the year-to-date result. The tax expense or benefit for the quarter represents the difference between the year-to-date tax expense or benefit for the current year-to-date period less such amount for the immediately preceding year-to-date period. Management considers the impact of all known events in its estimation of the Company's annual pre-tax income/loss and effective tax rate.
