State teachers' retirement: disability allowances and benefits.

Existing law, the Teachers' Retirement Law, establishes the State Teachers' Retirement System (STRS) and creates the Defined Benefit Program of the State Teachers' Retirement Plan, which provides a defined benefit to members of the program, based on final compensation, credited service, and age at retirement, subject to certain variations. STRS is administrated by the Teachers' Retirement Board. The Defined Benefit Program is funded by employer and employee contributions, as well as investment returns and state appropriations, which are deposited or credited to the Teachers' Retirement Fund, which is continuously appropriated for the purposes of the system.
