     Income tax expense from continuing operations was as follows (in thousands):

	Three Months Ended						Six Month Ended
	June 30,						June 30,
	2011			2010			2011			2010
Income tax expense	$	32,703		$	11,763		$	12,806		$	60,775
Effective tax rate		41.7	%		40.0	%		50.9	%		38.9	%

     We compute our quarterly taxes under the effective tax rate method based on applying an anticipated annual effective rate to our year-to-date income, except for discrete items. Income taxes for discrete items are computed and recorded in the period that the specific transaction occurs. For the three months ended June 30, 2011 and 2010, our overall effective tax rate on pre-tax income from continuing operations was different than the statutory rate of 35% due primarily to state income taxes, valuation allowances and other permanent differences. For the six months ended June 30, 2011 and 2010, our overall effective rate on pre-tax income from continuing operations was different than the statutory rate of 35% due primarily to state income taxes, valuation allowances and other permanent differences.
