Public Employee Retirement Information System (PERIS)




File Formats and Coding Values

The PERIS file formats are different from the old MPERA file formats. Please read them carefully. Note: The intent is to give vendors and in-house software developers what they need to work with the new file format and codes. Hopefully, this site will help with planning and development. There could be additions of codes or values. The file format (i.e. input file structures) are final. When you have questions, please contact the MPERA Technical Team.
