1The amounts in euro as laid down in Article 16a(3) and (4) and Article 17(2) shall be reviewed annually starting 20 September 2003 in order to take account of changes in the European index of consumer prices comprising all Member States as published by Eurostat.
The amounts shall be adapted automatically by increasing the base amount in euro by the percentage change in that index over the period between the entry into force of this Directive and the review date and rounded up to a multiple of EUR 100 000.
If the percentage change since the last adaptation is less than 5 %, no adaptation shall take place.
2. The Commission shall inform annually the European Parliament and the Council of the review and the adapted amounts referred to in paragraph 1.
