California Insurance Commissioner Steve Poizner proposed emergency changes Monday to regulations that help determine rates for auto and homeowner policies, saying the changes would “help speed lower insurance rates to consumers,” the Los Angeles Times rerpots.

The proposal would make changes to the formulas used to set rates.
