Wind or Hail Percentage Deductible Calculations

May 14, 2012

Our insured has commercial property coverage for three buildings at one location in Florida with wind deductible of 5 percent per an ISO Wind or Hail Percentage Deductible endorsement, CP 03 21 06 95. If a wind or hail event damages only one of the buildings at this location, is the 5 percent deductible calculated on the insured value of that damaged building or 5 percent of the insured value of all three buildings? For example, building #1 insured for $100,000, building #2 insured for $200,000, and building #3 insured for $300,000. If only building #1 suffers wind or hail damage, is the deductible $5,000 (5% of 100k) or $30,000 (5% of 600k) ?
