Public retirement benefits: excess salaries.

The Public Employees' Retirement Law (PERL) creates the Public Employees' Retirement System (PERS) , which provides a defined benefit to its employees based on age at retirement, service credit, and final or highest compensation paid to the employee. In the case of an employee who has been employed by one or more contracting public agencies, retirement benefits distributed to that employee is the obligation of all of contracting public agency employers and is prorated to each of the contracting public agencies based upon the number of years that the employee worked for each of those agencies.
