Share Incentive Plans
2015 Equity Incentive Plan
In 2015, our shareholders and board of directors approved the 2015 Equity Incentive Plan, as amended and restated, which we refer to as the 2015 Plan in this annual report, to attract and retain the best available personnel, provide additional incentives to employees, directors and consultants, and promote the success of our business. As of March 31, 2023, the maximum aggregate number of ordinary shares that may be issued under the 2015 Plan is 61,605,996 ordinary shares. As of March 31, 2023, 55,484,489 ordinary shares have been issued upon exercise of options and vesting of other share awards, options to purchase a total of 39,462,804 ordinary shares and 16,021,685 restricted share units are outstanding under the 2015 Plan.
The following paragraphs summarize the principal terms of the 2015 Plan.
Type of awards. The 2015 Plan permits the awards of options, share appreciation rights, restricted share awards, restricted share unit awards, and other share awards.
Plan administration. Our board of directors or a committee delegated by the board of directors will administer the 2015 Plan. The plan administrator will determine the participants to receive awards, when and how awards will be granted, the type, fair market value and number of awards to be granted to each participant, and the terms and conditions of each grant.
Award agreement. Awards granted under the 2015 Plan are evidenced by an award agreement that sets forth the terms, conditions and limitations for each award, which may include the provisions applicable in the event that the grantee’s employment or service terminates, and our sole and complete authority to amend, modify, suspend, cancel or rescind the award.
Eligibility. We may grant awards to our employees, directors and consultants.
Vesting schedule. In general, the plan administrator determines the vesting schedule, which is specified in the relevant award agreement.
Exercise of options. The plan administrator determines the exercise price for each award, which is stated in the relevant award agreement. Options that are vested and exercisable will terminate if they are not exercised prior to the time as the plan administrator determines at the time of grant. However, the maximum exercisable term is ten years from the date of grant. In addition, the participants can only exercise vested options upon the occurrence of our initial public offering.
Transfer restrictions. Awards may not be transferred in any manner by the participant other than in accordance with the exceptions provided in the 2015 Plan or the relevant award agreement or otherwise determined by the plan administrator, such as transfers by will or the laws of descent and distribution.
Termination and amendment. Unless terminated earlier, the 2015 Plan has a term of ten years from its date of effectiveness. Our board of directors has the authority to suspend or terminate the 2015 Plan at any time. However, without the written consent of the participant, such suspension and termination of the 2015 Plan will not impair rights and obligations under any award granted while the 2015 Plan is in effect.
