N.J. Stat. Ann. § 17:48C-24

If the commissioner shall determine that the amount disbursed during any 12-month period by a dental service corporation as expenses of operation is excessive in proportion to the amount it received from subscribers during that period, the corporation shall reduce its expenses during the 12-month period next following notification of the commissioner's determination to the proportion directed by the commissioner. In making his determination the commissioner shall give consideration to the number of subscribers enrolled, the aggregate payments by subscribers, the length of time the corporation has been certified as a dental service corporation, the expense rates of hospital, medical and dental service corporations of this and other States under similar conditions and any other relevant facts. In no event shall a dental service corporation disburse an amount during any 12-month period for expenses of operation greater than 30% of the amount it receives from subscribers during that period.
