the balance for employees retiring in 2015 and after, to additional creditable service based on a conversion table, where 2,087 hours equals one full year of additional creditable service. The leave can only increase the amount of creditable service for annuity purposes; it cannot be used to create an eligibility which did not exist (e.g. to either make an otherwise ineligible person eligible for retirement). For example, a person born in 1965, age 56 years and two months, with 29 years and 10 months' actual creditable service, plus sick leave hours which equate to four months of creditable time, would not be eligible for retirement (even though, for annuity calculation purposes, s/he would be credited with 30 years and two months of creditable service), because although s/he has reached the MRA s/he lacks the actual creditable service required to retire. The actual calculation of creditable service adds years, months, and days separately for civilian employment, military employment repurchased, and unused sick leave. For example, an employee with 33 years, 11 months, and 17 days of actual service time, plus four months and 20 days of unused sick leave, will be calculated as having 33 years, 15 months, and 37 days of time. The days are then converted to months at a rate of 30 days = one month, with any excess days lost (in this case, the 37 days will convert 30 days to one month, with the remaining seven days lost, leaving the employee with 33 years and 16 months). The months are then converted to years at a rate of 12 months = one year, with the remaining months shown as a fraction (in this case, the 16 months will convert 12 months to one year, leaving the employee with 34 years and four months, or 34 4/12 years for annuity calculation purposes). No other types of earned leave are factored into the annuity calculation. Unused annual leave hours are "cashed out" (paid to the employee, at his/her rate of pay as if the employee remained on the payroll until the leave was fully used; in the event of an intervening COLA leave remaining after its effective date will be paid at the new rate). Where applicable, earned but unused credit hours are also cashed out upon retirement at the same rate as annual leave. Other types of unused leave (such as compensatory time off for travel outside
