NAP = Net Annualized Premiums.
Example #1: November 2019, you closed a monthly case with a total APE of P100,000. The NAP covered here will only be good for two months - November and December. So NAP for this case is P16,667 (P100,000 / 12 months in a year = P8,333.33 x 2 months left for 2019 = P16,667).
Example #2: November 2019, you closed an annual case with a total APE of P100,000. The NAP covered will be good for one whole year. Total NAP is P100,000.
