Update on quarterly financial information 6.4.4 Following the publication on February 3, 2015 by the French Financial Markets Authority of a recommendation regarding the removal of the obligation to publish quarterly financial information, the Group has

decided not to publish quarterly information, most notably because the volatility of the Environmental Services business requires a somewhat

longer horizon to evaluate changes in figures.
