N.J. Stat. § 17:50-5
There shall be maintained at all times by the exchange, a reinsurance reserve in cash or securities authorized by the laws of the State in which the principal office of the attorney is located for the investment of similar funds of insurance companies doing the same kind of business, in an amount equal to fifty per centum (50%) of the net annual premium deposits collected and credited to the accounts of subscribers on policies having one year or less to run and pro rata on those for longer periods, or, in lieu thereof, one hundred per centum (100%) of the net unearned premium deposits collected and credited to the accounts of subscribers calculated separately for each policy in force as of any given date. In addition to the reserves provided for in this section, there shall also be maintained at all times at the exchange, as assets, a surplus in cash or such securities as aforesaid of not less than the amount of minimum capital and surplus required of a domestic stock insurance company to do the kind or kinds of insurance which it is authorized to write under section one of this act. There shall also be maintained at all times in the hands of the attorney, as a claim or loss reserve, in cash or such securities as aforesaid, assets sufficient to discharge all liabilities on all outstanding or accrued losses arising under policies issued, which are to be calculated in accordance with the laws of the State relating to similar reserves for companies insuring similar risks. If at any time the amounts on hand are less than the foregoing requirements, the subscribers, or their attorney for them, shall make up the deficiency. Net premium deposits, as used in this act, shall be construed to mean the premium deposits made by subscribers after deducting therefrom the amount paid as return premiums upon canceled contracts and reinsurance in companies or associations licensed to do business in this State. If it appears that the amount of funds required in this section has not been accumulated, then the subscribers, or the attorney for them, shall immediately advance such sums as are needed to comply with the provisions of this section, and the funds so advanced shall not be treated as a liability at the exchange, and shall not be withdrawn except with the approval of the chief insurance officer of the State wherein the exchange is domiciled, and such advances shall be repaid only out of the surplus, over and above the minimum required by this section. If the subscribers, or their attorney for them, shall fail to advance sums necessary for the maintenance of such minimum reserves and surplus, within thirty days after receipt of notice from the Commissioner of Banking and Insurance so to do, then said Commissioner of Banking and Insurance shall take charge of and liquidate such exchange in the manner provided by law in the case of other insurers; and in the case of an exchange of another State said Commissioner of Banking and Insurance may revoke its license to transact business in this State.
