Generally, there can be only one effective date of coverage for a coverage group.
However, if a retirement system covers the positions of employees of the State and
one or more political subdivisions or the employees of two or more political subdivisions,
the State may if the retirement system is not divided into deemed retirement systems:
Choose a single coverage effective date for all members of the coverage group; or
Choose a different coverage effective date for any one of any combination of the political
Choose a different coverage effective date for the State or for the State and any
one or more of the political subdivisions.
These choices are available for agreements and modifications entered into on or after
September 13, 1960.
When there are different coverage effective dates, an employee will receive retroactive
coverage only for his services with the entity which employs him on the date that
controls retroactivity and then only to the extent retroactive coverage is provided
for the employees of that entity. The State may, however, provide additional retroactive
coverage for employees who work at different times for more than one of the employers
included in the coverage group.
This provision applies only to effective dates. In other respects there is no change
in the retirement system coverage group. One referendum must be held for the entire
system. Coverage is extended to all employees in positions under the system. The optional
exclusions taken and the date designated to control retroactive coverage are applicable
to the entire coverage group. Employees whose positions are brought under the retirement
system after the agreement is made applicable to the retirement system coverage group
are automatically covered.
