6 CORPORATE GOVERNANCE

1. Composition and operation of the Board of Directors

Each year, specifically on the occasion of its assessment, the Board of Directors considers the desirable balance of its composition and that of the Committees. Regarding the diversity and internationalization of the Saint-Gobain Group’s activities, it specifically provides for the presence of directors with international experience, and ensures that the profiles and competencies represented on the Board reflect, to the greatest possible extent, the diversity of challenges the Group may face, to guarantee to shareholders and the market that its tasks are executed with the necessary competency, independence and objectivity. It is envisaged that the Board will continue to reduce its size to bring its composition down

to 14 members, at the close of the General Shareholders’ Meeting to be held in 2017 (see chapter 6, sections 1.1.4 and 1.2.4). In addition, the Board decided during its meeting of November 24, 2016 to create the position of Lead Independent Director (Administrateur Référent), which will be taken on by Jean-Dominique Senard, independent Director since 2012, at the close of the General Shareholders’ Meeting of June 8, 2017. The Lead Independent Director will, in particular oversee the efficient running of the Company’s governance bodies (see this chapter 6, section 1.2.1).
