Note 6 — Reconciliation of Weighted Average Shares Outstanding and Share Repurchases

A reconciliation of the shares used in the computation of earnings per share follows:

	Three Months Ended October 31,				Six Months Ended October 31,
	2018		2017		2018		2017
Weighted average shares outstanding		57,426		57,013		57,451		57,100
Less: Unvested restricted shares		(47)		(138)		(59)		(152)
Shares used for basic earnings per share		57,379		56,875		57,392		56,948
Dilutive effect of stock options and other stock awards		491		679		563		685
Shares used for diluted earnings per share		57,870		57,554		57,955		57,633

Since their inclusion in the calculation of diluted earnings per share would have been anti-dilutive, options to purchase 157,167 shares of Class A Common Stock have been excluded for the three and six months ended October 31, 2018, respectively and 284,787 shares of Class A Common Stock have been excluded for the three and six months ended October 31, 2017, respectively.

There were no restricted shares excluded for the three and six months ended October 31, 2018. There were 26,740 restricted shares excluded for the three and six months ended October 31, 2017, respectively.
