Net Income Per Common Share

(5) Net Income Per Common Share

Basic income per common share is based on the weighted average number of common shares outstanding during the period. Diluted income per common share includes the dilutive effect of potential common shares outstanding. The following table sets forth the reconciliation of weighted average shares outstanding and diluted weighted average shares outstanding:

	Three Months Ended September 30,
	2017		2016
Weighted average shares outstanding		34,975		29,518
Dilutive effect of stock options and restricted stock awards and units		284		322
Diluted weighted average shares outstanding		35,259		29,840

The weighted average shares outstanding for the three months ended September 30, 2017 includes the effect of 5,122 shares to be issued in connection with the acquisition of certain products and related assets from Citron and Lucid (see Note 2).The Convertible Senior Notes (see Note 6) will only be included in the dilutive net income per share calculations using the treasury stock method during periods in which the average market price of Aceto’s common stock is above the applicable conversion price of the Convertible Senior Notes, or $33.215 per share, and the impact would not be anti-dilutive.

There were 61 common equivalent shares outstanding as of September 30, 2017 that were not included in the calculation of diluted net income per common share for the three months ended September 30, 2017 because their effect would have been anti-dilutive.
