In S21.02, C0090 (Sum insured) is defined as "The highest amount that the insurer can be obliged to pay out under the policy", which suggests it might be reported net of deductible. C0100 (Original deductible policyholder) is defined as "Part of the sum insured which is retained by the policyholder" which suggests Sum insured might be reported gross of deductible. Similarly, C0150 (Net retention of the insurer) is defined as "The net amount for which the insurer acts as risk carrier, i.e.: part of the sum insured that exceeds the original deductible of the policyholder and is not reinsured" which also suggests C0090 may be gross of deductible. Could you please advise whether the amount included in C0090 should be reported net of the policy deductible or gross of deductible?
