The PERS Board is charged with crediting earnings to the various PERS funds each year.
This process begins shortly after the close of a calendar year and finishes near the end of the first quarter of the new year.
Two of the most common questions I am asked is why the various earnings crediting rates differ from the annual earnings as reported by Oregon State Treasury and why those differences vary from fund to fund.
To explore these questions, it is first important to understand that while the PERS Board is responsible for making sure that earnings are credited, Oregon laws and Oregon Administrative Rules (OARs) define how these earnings are to be credited to most funds. The one exception is the Contingency Reserve, which the board has discretion to replenish if the fund balance goes below $50 million.
In addition to the earnings crediting that happens at the end of the year, other fund activities take place throughout the year.
For example, when members retire and/or withdraw their funds during the year, a calculation is done to determine and credit the amount of earnings attributable to their account up to that point.
At the same time, new money is constantly coming into the plan in the form of employer and member contributions. These new funds are deposited throughout the year as they are received and are subject to earnings for only the portion of the year that remains.
The timing of these two factors — member retirements and new employer or member contributions — accounts for most differences between PERS’ effective earnings crediting rates and the earnings reported by Treasury.
Looking at various funds, this tends to be more pronounced in the “younger” funds where the amount of new money being added to the fund is larger (more of the money in the fund is only there for a portion of the year after it is received).
Also, per OAR, PERS deducts administrative expenses from each fund. In 2021, expenses amounted to about 0.1% of fund balances.
In the end, PERS is a complicated retirement system, and applying earnings within it is equally complex. We take this complex process seriously to ensure that earnings for all of our funds are correctly calculated and credited.
