16.  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 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.  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..
