Income Taxes
The Company’s effective tax rate of 35.0% and 32.7% for the nine-month periods ended September 30, 2013 and 2012, respectively, differs from the statutory federal tax rate of 34% due primarily to state taxes, differences between U.S. and foreign tax rates, foreign losses incurred with no related tax benefit, non-deductible commissions, non-deductible meals and entertainment expenses, and provisions to reconcile our tax return deductions to the estimates in our prior year tax provision.
Fuel Tech had unrecognized tax benefits as of December 31, 2012 in the amount of $42, all of which, if ultimately recognized, will reduce Fuel Tech's annual effective tax rate. During the quarter ended September 30, 2013, the Company increased its accrual for unrecognized tax benefits to $104 as a result of an uncertain tax position related to the R&D tax credit taken on its 2012 tax return.
