Stock Incentive Plans
Our board of directors has approved and adopted share-based awards under four stock incentive plans, namely, the 2015 Stock Incentive Plan, or the 2015 Plan, the 2016 Stock Incentive Plan, or the 2016 Plan, the 2017 Stock Incentive Plan, or the 2017 Plan, and the 2018 Stock Incentive Plan, or the 2018 Plan. The terms of the 2015 Plan, the 2016 Plan and the 2017 Plan are substantially similar. The purpose of our stock incentive plans is to attract and retain the best available personnel, to provide additional incentives to our employees, directors and consultants and to promote the success of our business. Our board of directors believes that our long-term success is dependent upon our ability to attract and retain superior individuals who, by virtue of their ability and qualifications, make important contributions to our business.
Under the 2015 Plan, the 2016 Plan and the 2017 Plan, the maximum numbers of Class A ordinary shares which may be issued pursuant to all awards are 46,264,378, 18,000,000 and 33,000,000, respectively. Under the 2018 Plan, the maximum number of shares available for issuance pursuant to all awards is initially 23,000,000 Class A ordinary shares, which amount will automatically increase each year by the number of shares representing 1.5% of the then total issued and outstanding share capital of our company as of the end of each preceding year. As of December 31, 2020, awards to purchase an aggregate amount of 79,318,499 Class A ordinary shares under our stock incentive plans have been granted and are outstanding, excluding awards that were forfeited or cancelled after the relevant grant dates.
The following paragraphs describe the principal terms of the 2015 Plan, the 2016 Plan and the 2017 Plan.
Types of Awards. Our stock incentive plans permit the awards of options, restricted shares, restricted share units, share appreciation rights, dividend equivalent right or other right or benefit under each plan.
Plan Administration. Our board of directors or a committee of one or more members of the board of directors or officers will administer our stock incentive plans. The committee or the full board of directors, as applicable, will determine the grantees to receive awards, the type and number of awards to be granted to each grantee, and the terms and conditions of each award grant.
Award Agreement. Awards granted under our stock incentive plans are evidenced by an award agreement that sets forth terms, conditions and limitations for each award, which may include the term of the award, the provisions applicable in the event that the grantee’s employment or service terminates, and our authority to unilaterally or bilaterally amend the award.
Eligibility. We may grant awards to our employees, consultants and directors.
Vesting Schedule. Except as approved by the plan administrator, options to be issued to the grantees under the stock incentive plans shall be subject to a minimum four (4) year vesting schedule calling for vesting no earlier than the following, counting from the applicable grant date or vesting commencement date (as determined by the plan administrator) with respect to the total issued options: the option representing 25% of the Class A ordinary shares under the option shall vest at the end of the first twelve (12) months commencing from the vesting commencement date, with remaining portions vesting in equal monthly installments over the next thirty-six (36) months.
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, In the case of an option granted to an employee who, at the time the option is granted, owns (or, pursuant to Section 424(d) of the U.S. Code, is deemed to own) stock representing more than 10% of the total combined voting power of all classes of shares of us or our subsidiary or affiliate, the term of the option will not be longer than seven to ten years from the date of grant under the 2017 Plan, or five years from the date of grant under the 2015 Plan and the 2016 Plan.
