A. Before each policy year commences the Directors shall decide the percentage which is to be applied to the premium ratings of all ships entered for that year (other than Fixed Premium Entries) in ascertaining the Mutual Premium payable in respect of that policy year. This decision may be made at the same time as a decision to increase the premium ratings of entered ships pursuant to Rule 17(A).
B. An Owner of a ship (other than a Fixed Premium Entry) which is entered for any policy year shall be bound to pay by way of Mutual Premium in respect of such policy year a sum ascertained by multiplying the percentage ordered by the Directors pursuant to paragraph (A) of this Rule by the premium rating of the ship (as agreed between the Owner and the Managers and/or as increased pursuant to Rule 17(A), as the case may be) by the entered tonnage of the ship in the Association.
C. If at any time before the final instalment of Mutual Premium in respect of a policy year has become payable it shall appear to the Directors unlikely that the whole of such Mutual Premium (together with any transfers from reserves and provisions made for the credit of or in respect of such policy year) is required for the purposes set out in Rule 19;
i. the Directors may resolve to reduce the amount of Mutual Premium payable in respect of that policy year by declaring a Mutual Premium Discount, expressed as a percentage of the Mutual Premium or of any instalment thereof, and
ii. the liability of the Owners under paragraph (B) of this Rule to pay Mutual Premium shall be reduced accordingly.
