Retirement > MERS > Retiree > Change of Payment Option or Survivor Benefits
23. I had been retired just a few months when the amount of my retirement benefit changed. Why?
Your retirement benefit is generally based, in part, upon the salary earned and reported to CMERS during your last three years (or 36 months) of employment. Many times, verification of the salary paid for this period of time is not received in CMERS until after your first retirement payment has been issued. Once the CMERS receives your final wages from your municipality, your benefit will be adjusted with your new service credit and earnings.
