Savings achieved through drug discounts received by departments and governmental entities shall be calculated on a quarterly basis by the board. A prorated share of the savings of each department or governmental entity, based on the percentage of the department or entity patronage as it bears to the total quarterly patronage, shall first be distributed to the board to reimburse the board for the administrative costs of the program. After administrative costs are fully reimbursed, any remaining savings shall be returned to the respective departments and governmental entities based on the prorated basis.
