     The following table presents the Company's provision for income taxes and effective income tax rate for the periods below:

	Three months ended May 31,						Nine months ended May 31,
	2012			2011			2012			2011
Provision (benefit) for income taxes	$	8,667		$	(2,742	)	$	13,125		$	2,195
Effective income tax rate		37.6	%		37.1	%		37.8	%		24.0	%

     The increase in the Company's effective income tax rate during the first nine months of fiscal year 2012 was primarily attributable to a $1.1 million decrease in the Company's liability for unrecognized tax benefits resulting from the settlement of state tax audits during the first quarter of fiscal year 2011 and the expiration of tax credit programs during the second quarter of fiscal year 2012.
