27As is apparent from recital 339 to the contested decision, the undertakings’ cooperation with the Commission was governed, from 14 February 2002, by the Commission Notice on immunity from fines and reduction of fines in cartel cases (OJ 2002 C 45, p. 3; ‘the 2002 Leniency Notice’), which was replaced with effect from 8 December 2006 by a new Commission notice (OJ 2006 C 298, p. 17; ‘the 2006 Leniency Notice’). Akzo Nobel contacted the Commission on the basis of an application for leniency on 20 November 2006, that is before the entry into force of the 2006 Leniency Notice; therefore the 2002 Leniency Notice is applicable in the present case, as are, by way of exception under point 37 of the 2006 Leniency Notice, points 31 to 35 of the 2006 Leniency Notice.
