(h) Whenever an insurer has no legally effective rates as a result of the commissioner's disapproval of rates or other act, the commissioner shall specify interim rates for the insurer that protect the interests of all parties and may order that a specified portion of the premiums be placed in an escrow account approved by the commissioner. When new rates become legally effective, the commissioner shall order the escrowed funds or any overcharge in the interim rates to be distributed appropriately, except that refunds of less than ten dollars ($10) per policyholder shall not be required.
However, if the commissioner has disapproved rates pursuant to subdivision (c), the commissioner shall order the insurer in the interim to use, at a minimum, the approved advisory pure premium rates pursuant to subdivision (b) of Section 11750, as modified by the uniform experience rating plan established pursuant to subdivision (c) of Section 11734, without any deviations on account of any supplementary rate information and reflecting the actual expenses of the insurer, until the time that a final determination of rates is adjudicated and ordered through a hearing.
