For California life insurance reserves and nonforfeiture computations, which mortality table is the current statutory basis?

Why this is the answer

California's Standard Valuation Law (§§ 10489.2-10489.99) and the Standard Nonforfeiture Law (§§ 10159.1+) anchor reserve and value calculations to the prevailing Commissioners Standard Ordinary (CSO) mortality table. The 2017 CSO Table became the required basis for policies issued on or after January 1, 2020. Older tables (1958, 1980, 2001) remain valid for in-force business issued during their respective periods but are no longer the basis for new issues.
