[1] Includes restricted stock units granted to senior management with performance-based vesting criteria (in addition to service-based vesting criteria for any of such restricted stock units that are deemed to have been earned). As of June 30, 2018, 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 performance-based restricted stock units 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 (0.3 million shares, 84 thousand shares and 0.7 million shares for the fiscal years ended June 30, 2018, 2017 and 2016, respectively, after application of the 1.8x or 2.0x multiplier described above).
[2] The number of restricted stock units reflects the application of the award multiplier as described above (1.8x or 2.0x depending on the grant date of the applicable award).
[3] Represents the portion of restricted stock units granted with performance-based vesting criteria and reported at the actual number of shares issued upon achievement of the performance vesting criteria during the fiscal year ended June 30, 2018.
[4] Includes restricted stock units granted to senior management with performance-based vesting criteria (in addition to service-based vesting criteria for any of such restricted stock units that are deemed to have been earned). As of June 30, 2018, 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 performance-based restricted stock units, reported at the maximum possible number of shares (i.e., 0.2 million shares for the fiscal year ended June 30, 2018, 42 thousand shares for fiscal year ended June 30, 2017 and 0.3 million shares for the fiscal year ended June 30, 2016) that may ultimately be issuable if all applicable performance-based criteria are achieved at their maximum and all applicable service-based criteria are fully satisfied.
[5] Share numbers reflect actual shares subject to awarded restricted stock units. As described above, under the terms of the 2004 Plan, the number of shares subject to each award reflected in this number is multiplied by either 1.8x or 2.0x (depending on the grant date of the award) to calculate the impact of the award on the share reserve under the 2004 Plan.
[6] Represents the portion of restricted stock units granted with performance based vesting criteria and reported at the actual number of shares issued upon achievement of the performance vesting criteria during the fiscal year ended June 30, 2018.
