Last year, the Legislature asked CalSTRS to submit a report detailing at least three options for addressing the unfunded liabilities of the pension system's Defined Benefit (DB) Program, which are now estimated by system actuaries to total about $70 billion. This handout for the Legislature's Public Employment and Retirement Committees (1) describes the risks of waiting to address CalSTRS' unfunded liabilities, (2) compares CalSTRS' unfunded liabilities to California's other long-term liabilities, (3) and examines possible sources for additional funding. We recommend that the Legislature adopt a plan that aims to fully fund CalSTRS' unfunded liabilities in about 30 years. A companion video further explains our findings and recommendations.
