[1] | During the fiscal year ended June 30, 2015, the Company adjusted the number of shares subject to outstanding options under the 2004 Plan by an aggregate of 4,245 shares pursuant to a proportionate and equitable adjustment for the effect of the special cash dividend, as required by the 2004 Plan. The total number of outstanding options under the 2004 Plan as well as the associated exercise prices were adjusted to ensure the aggregate intrinsic value remained the same after considering the effect of the special cash dividend. As the adjustment was required by the 2004 Plan, under the authoritative guidance, the adjustment to the outstanding awards did not result in any incremental compensation expense. Additionally, the adjustment did not have an impact on the shares available for future issuance under the 2004 Plan.
[2] | Represents the portion of shares listed as “Options canceled/expired/forfeited” above that were issued under the Company’s equity incentive plans other than the 2004 Plan and the Outside Director Plan. Because the Company is only currently authorized to issue equity awards under the 2004 Plan and the Outside Director Plan, any equity awards that are canceled, expired or forfeited under any other Company equity incentive plan do not result in additional shares being available to the Company for future grant.
[3] | 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, 2017, 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 (84 thousand shares, 0.7 million shares and 0.6 million shares for the fiscal years ended June 30, 2017, 2016 and 2015, respectively, after application of the 1.8x or 2.0x multiplier described above).
[4] | 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).
[5] | 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, 2017, 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., 42 thousand shares the fiscal years ended June 30, 2017 and 0.3 million shares for each of the fiscal years ended June 30, 2016 and 2015) 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.
[6] | 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.
