Unearned premiums are accrued premiums already written for future<br />

risk periods. For primary insurance, these premiums are calculated<br />

separately for each insurance policy pro rata temporis; for reinsurance,<br />

nominal percentages are used in some cases where the data<br />

for a calculation pro rata temporis is not available. The posting of<br />

unearned premiums is restricted to short-term underwriting business,<br />

i.e. property-casualty and health business in both primary<br />

insurance and reinsurance.<br />

The provision for future policy benefits in long-term insurance<br />

business is posted for the actuarially calculated value of obligations<br />

arising from policyholders’ guaranteed entitlements. As well as life<br />

insurance, this concerns portions of health and personal accident<br />

insurance, insofar as the business is conducted like life insurance.<br />

Measurement is usually based on the prospective method, by determining<br />

the difference between the present values of future benefits<br />

and future premiums. The actuarial assumptions used for their calculation<br />

include, in particular, assumptions relating to mortality, disablement<br />

and morbidity, as well as assumptions regarding interestrate<br />

development, lapses and costs. These are estimated on a realistic<br />

basis at the time the insurance contracts are concluded and they<br />

include adequate provision for adverse deviation to make allowance<br />

for the risks of change, error and random fluctuations. The actuarial<br />

assumptions are adjusted if this is shown to be necessary by a liability<br />

adequacy test in accordance with IFRS 4.<br />

The measurement of the provisions for future policy benefits<br />

depends on the type of contract, being based either on FAS 60 (life<br />

primary insurance without performance-related participation in<br />

surplus, health primary insurance and the bulk of reinsurance), on<br />

FAS 97 (life primary insurance with limited premium payment, life<br />

primary insurance on the universal life model, unit-linked life insurance<br />

and life reinsurance for assumed policies based on FAS 97) or<br />

on FAS 120 (life primary insurance with performance-related participation<br />

in surplus).<br />

For contracts in accordance with FAS 60, the provision for future<br />

policy benefits is calculated from the present value of estimated<br />

future policy benefits (including claims adjustment expenses) less<br />

the present value of future net level premiums. Net level premium is<br />

that part of the gross premium that is needed to finance future policy<br />

benefits. Life primary insurance contracts with limited premium<br />

payment as per FAS 97 are generally valued in the same way as<br />

contracts falling under FAS 60. For all other contracts as per FAS 97,<br />

an account is kept to which net level premiums and interest earnings<br />

are credited and from which risk premiums and administration<br />

expenses are debited, not all credits and debits being contractually<br />

fixed at the time the contracts are concluded. The provision for future<br />

policy benefits for life primary insurance where policyholders bear<br />

the investment risk themselves (unit-linked life insurance) is shown<br />

separately under equity and liabilities item D. In the case of contracts<br />

162<br />

as per FAS 120, the provision for future policy benefits comprises the<br />

net level premium reserve and liabilities for terminal dividends. The<br />

net level premium reserve is calculated from the present value of<br />

guaranteed policy benefits (including acquired bonuses but excluding<br />

claims adjustment expenses) less the present value of future net<br />

level premiums. The net level premium is the net premium less the<br />

portion of the premium envisaged for covering claims adjustment<br />

expenses. The actuarial assumptions are generally the same as<br />

those used for premium calculation. The provisions for terminal dividends<br />

is built up proportionally with a fixed share of the expected<br />

gross profit margins. The same method is used for this as for determining<br />

the amortisation of the deferred acquisition costs.<br />

The provision for outstanding claims is for payment obligations<br />

arising from insurance contracts in primary insurance and reinsurance<br />

at the balance sheet date. Part of the provision is for known<br />

claims for which individually calculated provisions are posted.<br />

Another part is for expenses for claims whose occurrence are not yet<br />

known (e.g. because they have not been reported yet or have not yet<br />

manifested themselves). A third class of provisions covers claims<br />

which are known but whose extent has turned out to be greater than<br />

originally foreseen. All these provisions include expenses for internal<br />

and external loss adjustment expenses. The provision for outstanding<br />

claims is based on estimates: the actual payments may be higher<br />

or lower. The amounts posted are the realistically estimated future<br />

amounts to be paid; they are calculated on the basis of past experience<br />

and assumptions about future developments (e.g. social, economic<br />

or technological parameters). Future payment obligations are<br />

generally not discounted; exceptions are some provisions for occupational<br />

disability pensions and annuities in workers’ compensation<br />

and other lines of property-casualty business, which we discount.<br />

For determining the provision for outstanding claims, the <strong>Munich</strong> <strong>Re</strong><br />

<strong>Group</strong> uses a range of actuarial projection methods. They include<br />

the chain ladder method and the Bornhuetter-Ferguson method. In<br />

applying the statistical methods, we regard large exposures separately.<br />

The standard actuarial methods we use are applied both to the<br />

run-off triangles for the payments and to the run-off triangles for the<br />

reported claims, so that we obtain a range of estimates for the<br />

ultimate loss. Within this range, a realistic estimated value for the<br />

ultimate loss is determined for the balance sheet date. By deducting<br />

the payments already made, we arrive at the provision for outstanding<br />

claims recognised in balance sheet.<br />

Other technical provisions mainly include the provision for premium<br />

refunds in primary insurance and the provision for profit commission<br />

in reinsurance. Provisions for premium refunds are posted<br />

in life and health primary insurance for obligations involving policyholder<br />

bonuses and rebates that have not yet been irrevocably<br />

allocated to individual contracts at the balance sheet date. Where
