[1] | Includes RSUs granted to executive management during the fiscal year ended June 30, 2019 with both a market condition and a service condition (“market-based RSUs”). Under the award agreements, the vesting of the market-based RSUs is contingent on achieving total stockholder return (including stock price appreciation and cash dividends) objectives on a per share basis of equal to or greater than 150%, 175% and 200% multiplied by the measurement price of $116.39 during the five-year period ending March 20, 2024. The awards are split into three tranches and, to the extent that total stockholder return targets have been met, one-third of the maximum number of shares available under these awards will vest on each of the third, fourth, and fifth anniversaries of the grant date. This line item includes all such market-based RSUs granted during the third quarter of the fiscal year ended June 30, 2019 reported at the maximum possible number of shares that may ultimately be issuable if all applicable market-based criteria are met at their maximum levels and all applicable service-based criteria are fully satisfied (0.8 million shares for the year ended June 30, 2019 reflects the application of the multiplier described above).
[2] | Includes RSUs granted to senior management with performance-based vesting criteria (in addition to service-based vesting criteria for any of such RSUs that are deemed to have been earned) (“performance-based RSUs”). As of June 30, 2019, it had not yet been determined the extent to which (if at all) the performance-based vesting criteria had been satisfied. Therefore, this line item includes all such performance-based RSUs granted during the fiscal year, reported at the maximum possible number of shares that may ultimately be issuable if all applicable performance-based criteria are achieved at their maximum levels and all applicable service-based criteria are fully satisfied (0.7 million shares, 0.3 million shares and 84 thousand shares for the fiscal years ended June 30, 2019, 2018 and 2017, respectively, reflects the application of the 1.8x or 2.0x multiplier described above).
[3] | Represents the portion of RSUs granted with performance-based vesting criteria and reported at the actual number of shares issued upon achievement of the performance vesting criteria during the year ended June 30, 2019 and 2018.
