Article 57
Provision for unearned premiums 1. The provision for unearned premiums shall in principle be computed separately for each insurance contract. Member States may, however, permit the use of statistical methods, and in particular proportional and flat-rate methods, where they may be expected to give approximately the same results as individual calculations. 2. In classes of insurance where the assumption of a temporal correlation between risk experience and premium is not appropriate, calculation methods shall be applied that take account of the differing pattern of risk over time.
