* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Each RSU represents a contingent right to receive one share of KLA common stock.
(2) On November 11, 2016, the reporting person was granted performance-based RSU for a target number of shares of KLA common stock equal to 33,454 shares with a performance condition based on the relative free cash flow of the Company compared to its peer group over the three years in the period ended September 30, 2019. The maximum number of shares eligible to vest under the PRSUs was 125% of the target number of shares. On November 22, 2019, it was determined that the performance condition had been met at 119% of the target shares. 100% of the shares vested on November 22, 2019.
(3) Does not include performance-based RSUs, if any, held by the Reporting Person for which an assessment has not yet been made regarding the achievement of the applicable performance goals. Any such holdings will be reported on a Form 4 within two business days of the date such assessment is made.
(4) Pursuant to the terms of the grant, shares of KLA common stock were automatically withheld at vesting to cover required tax withholding. The fair market value of KLA common stock used for purposes of calculating the number of shares to be withheld was the closing price of KLA common stock as reported on November 22, 2019.
(5) Shares held under the Wallace Living Trust u/a/d 03/27/01, as amended, a trust of which the Reporting Person is a trustee and beneficiary.
