Note 3. Net Income per Share

The Company’s non-vested restricted share awards contain non-forfeitable rights to dividends and meet the criteria of a participating security as defined by Accounting Standards Codification (“ASC”) Topic 260, “Earnings Per Share”. Under the two-class method, net income per share is computed by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, net income is allocated to both common shares and participating securities based on their respective weighted average shares outstanding for the period. The following table sets forth the computation of basic and diluted net income per common share under the two-class method for the thirteen and twenty-six weeks ended March 2, 2019 and March 3, 2018, respectively:


	Thirteen Weeks Ended				Twenty-Six Weeks Ended
	March 2,		March 3,		March 2,		March 3,
	2019		2018		2019		2018
Net income attributable to MSC Industrial as reported	$	68,424	$	117,552	$	142,656	$	177,137
Less: Distributed net income available to participating securities		(5)		(22)		(24)		(59)
Less: Undistributed net income available to participating securities		(15)		(105)		(46)		(197)
Numerator for basic net income per share:
Undistributed and distributed net income available to common shareholders	$	68,404	$	117,425	$	142,586	$	176,881
Add: Undistributed net income allocated to participating securities		15		105		46		197
Less: Undistributed net income reallocated to participating securities		(15)		(104)		(46)		(196)

Undistributed and distributed net income available to common shareholders	$	68,404	$	117,426	$	142,586	$	176,882
Denominator:
Weighted average shares outstanding for basic net income per share		55,139		56,439		55,320		56,363
Effect of dilutive securities		223		453		299		335
Weighted average shares outstanding for diluted net income per share		55,362		56,892		55,619		56,698
Net income per share two-class method:
Basic	$	1.24	$	2.08	$	2.58	$	3.14
Diluted	$	1.24	$	2.06	$	2.56	$	3.12

Potentially dilutive securities		1,123		-		718		-

Potentially dilutive securities attributable to outstanding stock options and restricted stock units are excluded from the calculation of diluted earnings per share where the combined exercise price and average unamortized fair value are greater than the average market price of MSC common stock, and therefore their inclusion would be anti-dilutive.
