"The ACA's risk adjustment, reinsurance, and risk corridors programs are intended to protect against the negative effects of adverse selection and risk selection, and also work to stabilize premiums, particularly during the initial years of ACA implementation. Each program varies by the types of plans that participate, the level of government responsible for oversight, the criteria for charges and payments, the sources of funds, and the duration of the program."
