N.J. Stat. § 17:28-3
The maximum premium shall be expressed in the policy of a mutual company organized under any law of this State, and, in a company other than a life insurance company, it may be solely a cash premium or a cash premium and an additional contingent premium, which contingent premium shall not be less than the cash premium, but no such company shall issue an insurance policy for a cash premium and without an additional contingent premium until and unless it possesses a surplus above all liabilities of at least $300,000.00.
Wherever any company shall issue policies for cash premiums only, in pursuance of the authority of this section, it may waive all contingent premiums set forth in policies then outstanding. The issuance of policies for cash premiums only in pursuance of this section may not be exercised by any such company until written notice of intention to do so, accompanied with a certified copy of the resolution of the board of directors providing for the issuance of such policies, shall have been furnished the Commissioner of Banking and Insurance.
