At Alibaba, RSUs are subject to a 4-year vesting schedule: 0% vests in the 1st year, 50% at the end of the 2nd year (cliff), then 25% at the end of each of the 3rd and 4th years (cliff). Alternatively, Alibaba also has the following 4-year vesting schedule: 25% vests at the end of each year (cliff).

Depending on the nature and the purpose of the grant, share options and RSUs either vest with a standard 1-year cliff, or with a 2-year cliff before the first grant, which is less common.
