Actuarial valuation reports are prepared for every PERS-participating employer by the PERS actuary. In even years, the reports list all data that the actuary used to calculate the employer’s contribution rate for the next biennium that will begin in July of the next odd year. In odd years, valuations are only advisory.  

For more information about actuarial valuations, go to the Actuarial Valuations webpage. 

Also, review current and past employer contribution rates on the Contribution Rates webpage.
