EARNINGS PER SHARE [Abstract]

EARNINGS PER SHARE

17.  EARNINGS PER SHARE

The standards of accounting for earnings per share require companies to provide a reconciliation of the numerator and denominator of the basic and diluted earnings per share computations.  Basic and diluted earnings per share were calculated as follows:

	Year Ended September 30,
	2012		2011		2010
Numerator:
Net income	$	40,826	$	51,662	$	49,458
Denominator:
Weighted-average common shares		22,506,408		22,895,568		23,083,807
(Denominator for basic calculation)
Weighted-average effect of dilutive securities:
Share-based compensation		773,890		539,036		188,772
Diluted weighted-average common shares		23,280,298		23,434,604		23,272,579
(Denominator for diluted calculation)
Earnings per share:
Basic	$	1.81	$	2.26	$	2.14
Diluted	$	1.75	$	2.20	$	2.13

For the twelve months ended September 30, 2012, 2011, and 2010, approximately 1.3 million, 1.3 million and 2.6 million shares, respectively, attributable to outstanding stock options were excluded from the calculation of diluted earnings per share because the exercise price of the options was greater than the average market price of our common stock and, therefore, their inclusion would have been anti-dilutive.
