INCOME TAXES	NOTE 9. INCOME TAXES We are subject to U.S. federal income tax as well as income taxes in multiple state and foreign jurisdictions. Our effective tax rates for the three months ended June 30, 2011 and 2010 were 36.4% and 34.8%, respectively, and 39.7% and 38.3% for the six months ended June 30, 2011 and 2010, respectively. Our effective tax rate varies due to the mix of pre-tax profit between the U.S. and international taxing jurisdictions with varying statutory rates, permanent differences impacting mainly the U.S. effective rate, and discrete tax adjustments, such as tax expense or benefit recognized for uncertain tax positions. The variance between our effective rate and the U.S. statutory rate reflects the impact of permanent items, mainly non-deductible expenses such as fines and penalties, and expenses subject to statutorily imposed limitations such as meals and entertainment expenses, plus the impact of state income taxes. As of June 30, 2011 and December 31, 2010, we had $2.3 million and $2.2 million, respectively, of unrecognized tax benefits, net of federal tax benefit, which, if recognized, would impact our effective tax rate. We recognized tax expense of less than $0.1 million and $0.1 million in each of the quarters ended June 30, 2011 and 2010 related to these items. We have substantially concluded all U.S. federal and state tax matters through the year ended December 31, 2006. We record interest and penalties related to unrecognized tax benefits as income tax expense. We have accrued a liability of $0.9 million and $0.8 million for the payment of interest and penalties as of June 30, 2011 and December 31, 2010, respectively. We believe that it is reasonably possible that $0.9 million of our currently remaining unrecognized tax positions, each of which are individually insignificant, may be recognized in the next twelve months as a result of a lapse of statute of limitations and settlement of ongoing audits. No release of our deferred tax asset valuation allowance was made during the quarter ended June 30, 2011.
