N.J. Stat. § 17B:18-8
A mutual insurer organized under this Code may borrow or assume a liability for the repayment of a sum of money sufficient to defray the reasonable expenses of its organization, or to enable it to comply with any requirement of law or as a guaranty fund, upon agreement, which shall first be submitted to and approved by the commissioner, that the loan or advance, with interest, shall be repaid only out of the surplus, earnings or profits of the corporation with the approval of the commissioner whenever, in his judgment, its financial condition shall warrant. Any such loan or advance shall not form a part of the legal liabilities of the insurer, but until repaid all statements published or filed with the commissioner by the insurer shall show the amount thereof then unpaid.
