Within its insurance segments Fortis manages its Life and Non-life businesses separately. Life business includes insurance contracts covering risks related to the life and death of individuals. Life business also includes investment contracts with and without discretionary participation features (DPF). Non-life business includes four branches: Accident & Health, Motor, Fire and Other damage to property, covering the risk of property losses or claims liabilities. To analyse the insurance results, Fortis uses the concepts technical result, non-technical result and operating margin. Technical result includes premiums, fees and allocated financial income, less claims and benefits and less operating expenses. Realised capital gains and losses on investments backing certain insurance liabilities, amongst others separated funds, are part of the allocated financial income and thus included in technical result. Financial income, net of the related investment costs, is allocated to the various Life and Non-life branches based on the investment portfolios backing the insurance liabilities of these branches.

Non-technical result includes all income and costs, not allocated to the insurance or investment contracts and thus not reported in the technical result.

Realised and unrealised capital gains and losses on investments recognised in the income statement, backing the insurance liabilities of the various branches and not allocated to the technical result, are included in the operating margin.
