Strong operating performance in China facilitated the recognition of certain net operating losses and other deferred tax assets. The effective tax rate of 33.0% and 31.3% for the three and six months ended June 30, 2012, respectively, differed from the federal statutory rate primarily due to the effect of income earned by certain of the Company's foreign entities being taxed at lower rates than the federal statutory rate. As of June 30, 2013, the Company has recorded a $1,418 liability for gross unrecognized tax benefits. This amount includes $569 of unrecognized tax benefits which, if ultimately recognized, will reduce the Company's annual effective tax rate. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. As of June 30, 2013, the Company had accrued approximately $110 for the payment of interest and penalties.
