2. Net Income per Common Share

Basic net income per common share is computed by dividing net income by the weighted average number of common shares outstanding during the period. With regard to common stock subject to vesting requirements and restricted stock units issued to the Company’s employees and non-employee members of its Board of Directors, the calculation includes only the vested portion of such stock and units.

Dilutive net income per common share is computed by dividing net income by the weighted average number of common shares outstanding, increased by the assumed conversion of other potentially dilutive securities during the period.

The following table reconciles basic and dilutive weighted average common shares:

	Quarter Ended
	March 30,		March 31,
	2018		2017
Basic weighted average common shares outstanding		29,089,356		28,867,950

Effect of dilutive securities:
Unvested restricted stock units and common stock subject to vesting requirements issued to employees and non-employees		370,339		990,499
Common stock issuable upon the exercise of stock options and SARs		2,355,118		2,433,965
Dilutive weighted average common shares outstanding		31,814,813		32,292,414

Approximately 0.7 million shares of common stock equivalents were excluded from the computations of diluted net income per common share for both the quarter ended March 30, 2018, and March 31, 2017, as their inclusion would have had an anti-dilutive effect on diluted net income per common share.
