California Code, Insurance Code - INS § 10235.91

In the event a non-medicaid national or state long-term care program is created through public funding that substantially duplicates benefits covered by the policy or certificate, the policyholder or certificate holder will be entitled to select either a reduction in future premiums or an increase in future benefits.  An actuarial method for determining the premium reductions and increases in future benefits will be mutually agreed upon by the department and insurers.  The amount of the premium reductions and future benefit increases to be made by each insurer will be based on the extent of the duplication of covered benefits, the amount of past premium payments, and claims experience.  Each insurer's premium reduction and benefit increase plans shall be filed and approved by the department.
