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

		Three months ended						Six months ended
		February 29,			February 28,			February 29,			February 28,
		2012			2011			2012			2011
Provision for income taxes	$	1,080		$	2,466		$	4,458		$	4,937
Effective income tax rate		39.2	%		36.2	%		38.3	%		29.9	%

     The increase in the Company's effective income tax rate during the second quarter of fiscal year 2012 was primarily due to tax credit programs that expired during the second quarter of fiscal year 2012. The higher effective income tax rate for the first half 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.
