Impact on share reserve multiplier |  | 2.0 |  |
[1] | 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).
[2] | Includes outstanding 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 September 30, 2016, it had not yet been determined the extent to which (if at all) the performance-based vesting criteria of such restricted stock units had been satisfied. Therefore, this line item includes all such performance-based restricted stock units, reported at the maximum possible number of shares that may ultimately be issuable under such restricted stock units if all applicable performance-based criteria are achieved at their maximum and all applicable service-based criteria are fully satisfied. The restricted stock units granted during the three months ended September 30, 2016 did not contain performance-bested vesting criteria.
[3] | 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.
