Discount Rate (RHIA)

The discount rate used to measure the total OPEB asset at June 30, 2020 was 7.20 percent. The
projection of cash flows used to determine the discount rate assumed that contributions from

contributing employers are made at the contractually required rates, as actuarially determined. Based

on those assumptions, the RHIA plan’s fiduciary net position was projected to be available to make all
projected future benefit payments of current plan members. Therefore, the long‐term expected rate

of return on OPEB plan investments for the RHIA plan was applied to all periods of projected benefit
payments to determine the total OPEB asset.
Long‐Term Expected Rate of Return (RHIA)

To develop an analytical basis for the selection of the long‐term expected rate of return assumption,
in July 2017 the PERS Board reviewed long‐term assumptions developed by both Milliman’s capital
market assumptions team and the Oregon Investment Council’s (OIC) investment advisors. Each asset

class assumption is based on a consistent set of underlying assumptions and includes an adjustment
for the inflation assumption. These assumptions are not based on historical returns, but instead are
based on a forward‐looking capital market economic model. For more information on the Plan’s
