1. The amount in euro as laid down in Article 17c(2) shall be reviewed annually starting on 31 October 2012, in order to take account of changes in the Harmonised Indices of Consumer Prices of all Member States as published by Eurostat.
That amount shall be adapted automatically, by increasing the base amount in euro by the percentage change in that index over the period between 31 December 2009 and the review date and rounded up to a multiple of EUR 100000.
If the percentage change since the last adaptation is less than 5 %, no adaptation shall take place.
2. The Commission shall inform the European Parliament and the Council annually of the review and the adapted amount referred to in paragraph 1.
