15.	EARNINGS PER SHARE

Basic earnings per share (EPS) is calculated by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the period, excluding the effects of unvested restricted stock awards that have a right to receive non-forfeitable dividends, which are considered participating securities as prescribed by the two-class method under ASC 260 "Earnings per Share". Diluted EPS is calculated in a similar manner, but the weighted-average number of common shares outstanding during the period is increased to include the weighted-average dilutive effect of "in-the-money" stock options and unvested restricted stock shares using the treasury stock method.

Pursuant to the adoption of ASU 2016-09 in the first quarter of fiscal 2018, the tax benefits associated with share-based compensation plans were recorded as a tax benefit in our Consolidated Statements of Income. The number of shares that would be repurchased with the proceeds from the tax benefits was excluded from the diluted weighted average shares outstanding using treasury stock method under the new guidance.

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:

	Three Months Ended June 30,						Nine Months Ended June 30,
	2018			2017			2018			2017
Numerator:
Net Income	$	35,171		$	19,939		$	61,825			60,450
Less: income attributable to participating securities		(34	)		(52	)		(73	)		(191	)
Earnings available to common shares	$	35,137		$	19,887		$	61,752			60,259

Denominator:
Weighted average common shares		25,611,505			25,228,468			25,479,078			24,941,190
(Denominator for basic calculation)

Weighted average effect of dilutive securities:
Share-based compensation		707,133			492,247			742,786			508,317
Diluted weighted average common shares		26,318,638			25,720,715			26,221,864			25,449,507
(Denominator for diluted calculation)

Earnings per share:

Basic	$	1.37		$	0.79		$	2.42			2.42

Diluted	$	1.34		$	0.77		$	2.35			2.37

For both the three months ended June 30, 2018 and 2017, approximately 0.1 million shares attributable to outstanding stock options were excluded from the calculation of diluted earnings per share.

For the nine months ended June 30, 2018 and 2017, approximately 0.1 million and 0.4 million shares, respectively, attributable to outstanding stock options were excluded from the calculation of diluted earnings per share.
