The PERS pension plan is a defined benefit plan. Participants in the PERS plan receive a benefit upon retirement based on either: a) your years of service and compensation; or b) a specified monthly benefit based on your earnings history, years of service, and age. Your employer's contribution varies each year to ensure that the benefit is adequately funded.
The 401(a) Plan is a defined contribution plan. The amount of the employer's contribution is specifically defined, and this is the amount you'll receive in benefits from this plan, adjusted for any earnings or losses from your investments.
