INCOME TAXES
The Company's effective income tax rates were 26.4% and 20.7% for the three months ended March 31, 2014 and 2013, respectively. The Company's effective tax rate for the three months ended March 31, 2014 was lower than the applicable statutory tax rate of 35% primarily because of the Company's U.S. income tax positions. The Company does not have a history of significant taxable income in the U.S., therefore, the Company has recorded a valuation allowance against its U.S. federal tax net operating loss carryforwards. Accordingly, in instances when the Company's U.S. legal entities generate pre-tax book income, no income tax expense is recognized to the extent there are net operating loss carryforwards to offset pre-tax book income.
