Note 4. Loss Per Share

The following table sets forth the computation of the numerator and denominator used in the computation of basic and diluted net loss per share:

(in thousands, except per share amounts)	Three Months Ended						Six Months Ended
	September 30, 2011			September 24, 2010			September 30, 2011			September 24, 2010
Numerator:
Net loss	$	(7,394	)	$	(3,394	)	$	(15,814	)	$	(11,604	)
Denominator-weighted average shares of common stock outstanding:
Shares used to compute basic and diluted net loss per share		30,390			29,737			30,316			29,731
Basic and diluted net loss per share	$	(0.24	)	$	(0.11	)	$	(0.52	)	$	(0.39	)

The denominator for basic and diluted net loss per share is the weighted average number of unrestricted common shares outstanding for the periods presented. In periods of net income, the denominator for diluted net income per share also includes potentially dilutive shares, which consist of shares issuable upon the exercise of dilutive stock options and contingently issuable shares. These shares are excluded from the computations of diluted net loss per share for the three and six months ended September 30, 2011 and September 24, 2010 as they are anti-dilutive and would therefore reduce the loss per share. The total amount of such anti-dilutive shares was 60,000 and 121,000, respectively, for the three and six months ended September 30, 2011 and 231,000 and 312,000, respectively, for the comparable periods ended September 24, 2010.

At September 30, 2011, there are 770,000 shares of common stock issuable upon conversion of the 3¾% convertible senior notes and 753,000 shares of common stock issuable upon conversion of the 7¼% redeemable convertible subordinated debentures. For all periods presented, these shares and the related effect of the accrued interest are excluded from the calculation of diluted net loss per share, as their inclusion would be anti-dilutive.
