Insurance, investment and reinsurance contracts
Insurance contracts
Insurance policies which bear significant insurance risk are presented as insurance contracts. Provisions for liabilities under insurance contracts represent estimates of future payouts that will be required for life and non-life insurance claims, including expenses relating to such claims. For some insurance contracts the measurement reflects current market assumptions.
Provision for life insurance
The Provision for life insurance is calculated on the basis of a prudent prospective actuarial method, taking into account the conditions for current insurance contracts. Specific methodologies may differ between business units as they may reflect local regulatory requirements and local practices for specific product features in the local markets.
Insurance provisions on traditional life policies are calculated using various assumptions, including assumptions on mortality, morbidity, expenses, investment returns and surrenders. Assumptions for insurance provisions on traditional life insurance contracts, including traditional whole life and term life insurance contracts, are based on best estimate assumptions including margins for adverse deviations. The assumptions are set initially at the policy issue date and remain constant throughout the life of the policy, except in the case of loss recognition.
Insurance provisions for universal life, variable life and annuity contracts, unit-linked contracts, etc. are generally set equal to the balance that accrues to the benefit of the policyholders. Certain variable annuity products contain minimum guarantees on the amounts payable upon death and/or maturity. The insurance provisions include the impact of these minimum guarantees, taking into account the difference between the potential minimum benefit payable and the total account balance, expected mortality and surrender rates.
The as yet unamortised interest rate rebates on periodic and single premium contracts are deducted from the Provision for life insurance. Interest rate rebates granted during the year are capitalised and amortised in conformity with the anticipated recovery pattern and are recognised in the profit and loss account.
Provision for unearned premiums and unexpired insurance risks
The provision is calculated in proportion to the unexpired periods of risk. For insurance policies covering a risk increasing during the term of the policy at premium rates independent of age, this risk is taken into account when determining the provision. Further provisions are made to cover claims under unexpired insurance contracts, which may exceed the unearned premiums and the premiums due in respect of these contracts.
Claims provision
The Claims provision is calculated either on a case-by-case basis or by approximation on the basis of experience. Provisions have also been made for claims incurred but not reported (IBNR) and for future claims handling expenses. The adequacy of the Claims provision is evaluated each year using standard actuarial techniques. In addition, ‘IBNR’ reserves are set to recognise the estimated cost of losses that have occurred but which have not yet been notified to the Group.
Deferred profit sharing liability
For insurance contracts with discretionary participation features a deferred profit sharing liability is recognised for the full amount of the unrealised revaluation on allocated investments. Upon realisation, the profit sharing on unrealised revaluation is reversed and a deferred profit sharing liability is recognised for the share of realised results on allocated investments that is expected to be shared with policyholders. The deferred profit sharing liability is reduced by the actual allocation of profit sharing to individual policyholders.
Provisions for life insurance for risk of policyholders
The Provisions for life insurance for risk of policyholder are calculated on the same basis as the Provision for life insurance. For insurance contracts for risk of policyholders the provisions are generally shown at the balance sheet value of the associated investments.
Reinsurance contracts
Reinsurance premiums, commissions and claim settlements, as well as the reinsurance element of technical provisions are accounted for in the same way as the original contracts for which the reinsurance was concluded. To the extent that the assuming reinsurers are unable to meet their obligations, the Group remains liable to its policyholders for the portion reinsured. Consequently, provisions are made for receivables on reinsurance contracts which are deemed uncollectible.
Adequacy test
The adequacy of the Provision for life insurance, net of unamortised interest rate rebates, DAC and VOBA (the net insurance liabilities), is evaluated regularly by each business unit. The test considers current estimates of all contractual and related cash flows, and future developments. It includes investment income on the same basis as it is included in the profit and loss account.
If, for any business unit, it is determined, using a best estimate (50%) confidence level, that a shortfall exists, and there are no offsetting amounts within other business units in the Business Line, the shortfall is recognised immediately in the profit and loss account.
If, for any business unit, the net insurance liabilities are not adequate using a prudent (90%) confidence level, but there are offsetting amounts within other Group business units, then the business unit is allowed to take measures to strengthen the net insurance liabilities over a period no longer than the expected life of the policies. To the extent that there are no offsetting amounts within other Group business units, any shortfall at the 90% confidence level is recognised immediately in the profit and loss account.
If the net insurance liabilities are determined to be adequate at above the 90% confidence level, no reduction in the net insurance liabilities is recognised.
Investment contracts
Insurance policies without discretionary participation features which do not bear significant insurance risk are presented as Investment contracts. Provisions for liabilities under investment contracts are determined either at amortised cost, using the effective interest method (including certain initial acquisition expenses) or at fair value.
