Net Loss per Share

We compute basic net loss per share by dividing net loss by the weighted average number of common shares outstanding during the period. To determine diluted share count, we apply the treasury stock method to determine the dilutive effect of outstanding stock option shares, restricted stock units ("RSUs"), and Employee Stock Purchase Plan ("ESPP") shares. Our application of the treasury stock method includes, as assumed proceeds, the average unamortized stock-based compensation expense for the period. When we are in a net loss position, we do not include dilutive securities as their inclusion would reduce the net loss per share.

A summary of basic and diluted net loss per share is presented in the following table:



	Three Months Ended						Six Months Ended
(in thousands, except per share data)	June 30, 2018			July 1, 2017			June 30, 2018			July 1, 2017
Net loss	$	(20,223	)	$	(13,022	)	$	(26,175	)	$	(20,297	)
Shares used in basic and diluted net loss per share	124,843			122,390			124,460			122,095
Basic and diluted net loss per share	$	(0.16	)	$	(0.11	)	$	(0.21	)	$	(0.17	)

The computation of diluted net loss per share excludes the effects of stock options, RSUs, and ESPP shares that are antidilutive, aggregating approximately the following number of shares:



	Three Months Ended		Six Months Ended
(in thousands)	June 30, 2018	July 1, 2017	June 30, 2018	July 1, 2017
Stock options, RSUs, and ESPP shares excluded as they are antidilutive	9,169	6,000	9,376	5,946

Stock options, RSUs, and ESPP shares are considered antidilutive when the aggregate of exercise price and unrecognized stock-based compensation expense are greater than the average market price for our common stock during the period or when the Company is in a net loss position, as the effects would reduce the loss per share. Stock options, RSUs, and ESPP shares that are antidilutive at June 30, 2018 could become dilutive in the future.
