4. Basic and Diluted Net Income Per Share

Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of common and dilutive common equivalent shares outstanding during the period. The number of dilutive common equivalent shares outstanding during the period has been determined in accordance with the treasury-stock method. Common equivalent shares consist of common stock issuable upon the exercise of outstanding options and common stock issuable upon the vesting of outstanding, unvested SUAs.

Basic and diluted weighted average common shares outstanding are as follows:

	Three Months Ended				Nine Months Ended
	September 30,		September 30,		September 30,		September 30,
	2012		2011		2012		2011
	(in thousands)
Weighted average common shares		5,272		5,238		5,256		5,228
Common equivalent shares		18		3		10		7
Weighted average common shares outstanding, assuming dilution		5,290		5,241		5,266		5,235

For the three months ended September 30, 2012 and 2011, options to purchase 231 thousand and 269 thousand common shares, respectively, were outstanding but not included in the diluted weighted average common share calculation as the effect would have been antidilutive. The amounts for the nine month period ended September 30, 2012 and 2011 were 264 thousand and 265 thousand common shares, respectively.
