(b) The maximum amount of total compensation, as defined in subdivision (a), payable by any insurer shall not exceed 35 percent of the prima facie credit life insurance rates and 30 percent of the prima facie disability insurance rates. Of the maximum total compensation allowable, the creditor shall be limited to a compensation rate of 27.5 percent of the prima facie credit life insurance rates and 23.75 percent of the prima facie credit disability insurance rates. The general agent's maximum total compensation allowable shall be limited to 7.5 percent of the prima facie credit life insurance rates and 6.25 percent of the prima facie credit disability insurance rates. A creditor may not receive both the creditor's and the general agent's compensation on its own produced insurance. A general agent may also receive additional primary compensation deducted from the maximum primary compensation allowable to the creditor. If the commissioner has reason to believe that compensation is in fact or is contracted to be in excess of the maximum amount specified in this section, the commissioner may conduct a hearing or investigation, including the right to examine any contracts relating to the direct or indirect payment of compensation, to determine whether the insurer, general agent, or any other person is paying or whether an agent, general agent, or broker is receiving any form of compensation in excess of the applicable maximum amount of compensation specified in this section.
