The claims basis shall be calculated, as follows:
The amounts of claims paid in respect of direct business (without any deduction of claims borne by reinsurers and retrocessionaires) in the periods specified in paragraph 1 shall be aggregated.
To that sum there shall be added the amount of claims paid in respect of reinsurances or retrocessions accepted during the same periods and the amount of provisions for claims outstanding established at the end of the previous financial year both for direct business and for reinsurance acceptances.
From that sum there shall be deducted the amount of recoveries effected during the periods specified in paragraph 1.
From the sum then remaining, there shall be deducted the amount of provisions for claims outstanding established at the commencement of the second financial year preceding the last financial year for which there are accounts, both for direct business and for reinsurance acceptances.
One third of the amount so obtained shall be divided into two portions, the first extending up to EUR 35 000 000 and the second comprising the excess; 26 % of the first portion and 23 % of the second, shall be added together.
The sum so obtained shall be multiplied by the ratio existing in respect of the sum of the previous three financial years between the amount of claims remaining to be borne by the IORP after deduction of amounts recoverable under reinsurance and the gross amount of claims. That ratio shall be no less than 50 %.
