During the second quarter of 2020, the Company's stockholders approved the reservation of an additional 1.6 million shares of common stock for future issuance under the Company's 2019 Incentive Plan. As of March 28, 2020, an aggregate of 8.5 million shares were authorized for future issuance under the Company's stock plans, of which 4.3 million of such shares were issuable upon exercise of outstanding options and delivery of shares upon vesting of restricted stock units and 4.2 million shares of common stock were available for future grant.

Restricted and Performance Stock Units

The Company grants restricted stock units and restricted stock units with performance conditions ("PSUs") to executive officers, directors and certain other employees. These units vest over periods ranging from 1 year to 4 years and/or upon achievement of specified performance criteria and are automatically exchanged for shares of common stock at the vesting date. If performance metrics are not met within specified time limits, the award will be canceled. Compensation expense associated with restricted stock units and PSUs is recognized ratably over the vesting period, subject to probability of achievement for PSUs.

During the first two quarters of 2020, the Company granted PSUs for 304,500 shares for which vesting are contingent on cumulative non-GAAP earnings per share measured over three fiscal years. If a minimum threshold is not achieved, no shares will vest. If the minimum threshold is achieved or exceeded, the number of shares of common stock that will be issued will range from 80% to 120% of the number of PSUs granted, depending on the extent of performance. Additionally, the number of shares that vest may be adjusted up or down by up to 15% based on the Company's total shareholder return relative to that of its peer group over this same period. These PSUs will expire on December 31, 2022 if such performance conditions have not been met.
