The principal amount of the Vitality Re IX notes, which are non-recourse to Aetna, and the coverage available under the reinsurance arrangement will be reduced by any payments to Aetna under the reinsurance arrangement. Aetna will be entitled to begin to receive payments from Vitality Re IX under the reinsurance arrangement if the MBR of the covered business for calendar year 2018 reaches an initial attachment point of 94%. The full $200 million of coverage would be paid to Aetna if the MBR of the covered business reaches an initial exhaustion point of 114% for calendar year 2018. The attachment and exhaustion points will be reset annually for 2019, 2020 and 2021 to maintain modeled probabilities of attachment and expected loss on the Vitality Re IX notes equal to the initial modeled probabilities of attachment and expected loss.
