1. For the purposes of this Directive, the ECU shall be that defined by Regulation (EEC) No 3180/78, as amended by Regulation (EEC) No 2626/84. The equivalent in national currency shall initially be calculated at the rate obtaining on the date of adoption of this Directive.
Member States may round off the amounts in national currency resulting from the conversion of the amounts in ECU provided such rounding off does not exceed 10 ECU.
2. Every five years, and for the first time in 1995, the Council, acting on a proposal from the Commission, shall examine and, if need be, revise the amounts in this Directive, in the light of economic and monetary trends in the Community.
