The department shall set a capitated rate of payment that is actuarially sound and that is based on the number of beneficiaries who are eligible for Medi-Cal benefits to be enrolled in the pilot project, the mix of provided services and programs being integrated, and past Medi-Cal expenditures for services. The rate shall reflect, and the contract shall delineate, the rate at which the local long-term care services agency shall assume the total risk and the mechanisms that shall be used, which may include, but are not limited to, risk corridors, reinsurance, or

alternative methods of risk assumption.
