To set up leave types, there are many options available. Here are some important ones:

1. Leave Type Name: Public name to identify the PTO/Leave policy
2. Description: Optional field to explain the details of the leave type. You can also include references and examples here.
3. Track Leave Policy: How do you want to track the leave policy in days or hours.
4. Definition of days count: Defines the days to be count while applying for leave -
   1. In the case of working days: Only the working days configured in the system will be counted while requesting a leave.
   ‍2. In the case of calendar days: Weekends, holidays, or non-working days will also be count while requesting a leave.
5. Leave year starts at: When do you want the leave year to start, either it can be the beginning of the calendar year, Work Anniversary, or a specific date.
6. Leave request beyond balance: Allows the employees to request a Leave if the available balance is 0 or less.
7. Accrual Details: Annual Accrual Rate (Hours): Maximum number of hours that an employee will earn in the course of a year under this particular leave type.  

‍Accrual Type:

1. Continuous Accrual: Employees will earn time progressively and proportionately as the year goes by.
2. Accrual at the beginning of the period: Employees are entitled to the full/maximum number of hours defined under the “annual accrual rate” at the beginning of the period.
3. Accrual Threshold (Weeks): Minimum number of weeks an employee should be in the company, for this policy to take effect. An employee can be assigned to this policy as part of their onboarding, but the policy will not be available to the employee until the “accrual threshold” time has passed from the joining date.

Carryover Details:

1. Carryover (Percentage): Percentage of the remaining balance at the end of the period that can be carried over to the next period. This is also called “Rollover Percentage”. For example, if you set carryover percentage as 50%, and a team member has 80 hours at the end of their leave year, only 40 hours will be carried over after that leave year ends. If you set carryover percentage to 0, that translates as "No Carryover". If you have maximum carryover or expiration date specified, it is quite common to have this field set to 100%.
2. Maximum Carryover (Hours): Maximum number of hours that can be carried over to the next period.  This is also called “Maximum Rollover”.
3. Carryover expires after: Select the time span after which the carryover will expire.
