Computation of Net Loss Per Share

8. Computation of Net Loss Per Share

Basic net loss per common share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per common share is computed by dividing net loss by the weighted-average number of common and dilutive common equivalent shares outstanding during the period. In the loss periods, the shares of common stock issuable upon exercise of stock options and warrants or upon vesting of restricted stock units are excluded from the computation of diluted net loss per share, as their effect is anti-dilutive.

For fiscal 2013, 2012, and 2011, the following options and warrants to purchase shares of common stock and restricted stock units were excluded from the computation of diluted net loss per share, as the inclusion of such shares would be anti-dilutive:

	Fiscal 2013		Fiscal 2012		Fiscal 2011
Stock options		8,823,041		8,142,468		8,083,896
Stock warrants		53,957		1,201,116		6,155,170
Restricted stock units(1)		2,904,423		2,617,188		1,798,213

(1) Includes 1,267,215, 1,600,564, and 1,413,481 shares of restricted stock in fiscal 2013, 2012, and 2011, respectively, awarded to directors that have vested but are still restricted until the directors resign.
