D. The company may deduct from such loan value any existing indebtedness on or secured by the policy not already deducted in determining such cash value including interest due or accrued, and any unpaid balance of the premium for the current policy year, and any interest which may be allowable on the loan to the end of the current policy year; provided, that the policy shall reserve to the insurer the right to defer the granting of a loan, other than for the payment of any premium to the insurer, for six (6) months after the application therefor is made. The policy may also provide that if interest on any indebtedness is not paid when due it shall then be added to the existing indebtedness and shall bear interest at the same rate, and that if and when the total indebtedness on the policy, including interest due or accrued, equals or exceeds the amount of the loan value thereof, then the policy shall terminate and become void, but not until at least thirty (30) days' notice shall have been mailed by the insurer to the last-known address of the insured or policy owner and of any assignee of record at the home office of the insurer. The policy, at the insurer's option, may provide for an automatic premium loan, subject to an election of the party entitled to elect. No condition other than as herein provided shall be exacted as a prerequisite to any such loan. This provision shall not be required in term insurance, nor shall it apply to temporary insurance or pure endowment insurance, issued or granted in exchange for lapsed or surrendered policies.
