Income Taxes	9 Months Ended
	Sep. 30, 2011
Income Taxes
Income Taxes	6.  Income Taxes The Company’s effective income tax rates for the nine months ended September 30, 2011 and 2010 were 32.2% and 33.4%, respectively. The decrease in the effective income tax rate was primarily due to favorable state law changes to apportionment weights, statute expirations and settlements for uncertain tax positions, and the Continental acquisition, which caused a shift in our state apportionment rates that lowered our state income tax rates as well as increased our foreign income levels that are taxed at lower rates.
