For the three and nine months ended September 30, 2015 and 2014, the Company's effective tax rate differed from the U.S. federal statutory rate primarily due to state and local income taxes. Additionally, effective as of this quarter, the Company is no longer asserting that the unremitted earnings of its Canadian business are indefinitely reinvested. As a result of the change in the reinvestment assertion, the income tax expense for the three and nine months ended September 30, 2015 included approximately $3.3 million of withholding tax expense on the unremitted earnings of its Canadian business. The Company is asserting that the unremitted earnings of its UK business are indefinitely reinvested.
