Net Income (Loss) per Share

Our calculation of the diluted share count includes the number of shares from our equity awards with market conditions or performance conditions that would be issuable under the terms of such awards at the end of the reporting period. The maximum number of shares issuable under the equity awards with a market condition are included in the diluted share count as of June 29, 2019, as the market condition would have been achieved at the highest level of vesting if measured as of the end of the reporting period. No shares related to the performance conditions are included in the diluted share count as of June 29, 2019, as vesting of these awards is contingent upon evaluation of the performance condition over two consecutive trailing four-quarter periods, which have not yet elapsed. See "Note 9 - Stock-Based Compensation" to our consolidated financial statements for further discussion of our equity awards with market conditions or performance conditions.

A summary of basic and diluted Net income (loss) per share is presented in the following table:

The computation of diluted Net income (loss) per share excludes the effects of stock options, Restricted Stock Units ("RSUs"), Employee Stock Purchase Plan ("ESPP") shares, and equity awards with a market condition or performance condition that are antidilutive, aggregating approximately the following number of shares:



	Three Months Ended		Six Months Ended
(in thousands)	June 29, 2019	June 30, 2018	June 29, 2019	June 30, 2018
Stock options, RSUs, ESPP shares, and equity awards with a market condition or performance condition excluded as they are antidilutive	73	9,169	210	9,376

Stock options, RSUs, and ESPP shares that are antidilutive at June 29, 2019 could become dilutive in the future.
