This search is for a Total Fund Enterprise Risk Management System. PERS has three distinct pools of assets: Defined Benefit, Health Care and Defined Contribution. For the Defined Benefit and Health Care plans, OPERS utilizes plan accounting to split the ownership of our underlying portfolio accounts. The split proportions of account ownerships between Defined Benefit and Health Care can, and do, change dynamically over time. Any prospective system will need to be able to accommodate this structure and will need to provide risk measurement on each pool individually, as well as the combined total OPERS plan.
