Several plans are sponsored either by the state or another governmental entity within California. The largest of such plans is the California Public Employees’ Retirement System (CalPERS), which provides both retirement and welfare benefits to various categories of employees, including both safety (e.g., police and fire) and miscellaneous employees of the state and those local governmental entities, such as cities, counties, and special districts, that enter into a contract for CalPERS to provide such benefits. Other state or local government sponsored plans include among others: (1) the State Teachers' Retirement System (CalSTRS), which provides retirement and certain other benefits to primary, secondary, community college and adult education school teachers within the state, (2) the University of California Retirement System, (3) various county retirement systems established under the County Employees Retirement Law of 1937, and (4) systems established under the Legislators' Retirement Law and the Judges' Retirement Law.
