Every such policy of fire insurance may, subject to the provisions of section 1 hereof as to filing with and possible disapproval by the Commissioner of Banking and Insurance, include any other insurances which the insurer is authorized to make. Two or more insurers may issue in combination a policy authorized by this section, under the terms of which policy each of such insurers will provide coverage against one or more of the specified insurances.
Whenever other insurances which the insurer is authorized to make are included in any such policy of fire insurance and there is no separate premium for fire insurance, the insurer, if not organized under the laws of this State, shall allocate that much of the premium which is fairly attributable to fire insurance for the purpose of determining taxes pursuant to R.S. 54:17-4, 54:18-1 and 54:18-2.
