Annual Leave Policies in India: How Do Companies Handle Carryover and Encashment?

Is it common to state in the annual leave policy that there is a carryover of days? If so, how many days is most common.

Is it common to state that there is encashment of unused annual leave days? If so, how many days are typically allowed for carryover or accumulation.

Question 1: Is there an option to not carry forward annual leave to the next year? If such a policy exists, kindly inform me.

Question 2: If the carry-forward option for annual leave is available, please let me know the maximum number of leaves that can be carried over to the next year.
