We will set the rate of interest at not less than the Minimum Interest Paid on Death Claims percentage shown in the Data Section. COST OF ADDITIONAL PROTECTION BENEFIT.

On any Monthly Policy Date, the Cost of Additional Protection Benefit shall be the product of: 1. the Cost of Additional Protection Benefit rate on such date divided by $1,000; multiplied by 2. the Additional Protection Benefit on such date, divided by the sum 1 plus the monthly Accumulated Value Interest Rate shown in the Data Section. We may change the Cost of Additional Protection Benefit rates from time to time based on our expectations of future experience.
