1 The total number of theoretical (or “gross”) voting rights is used as the basis for calculating threshold crossings. In accordance with Article 223-11 of the AMF General Regulations, this number is calculated on the basis of all shares to which voting rights are attached, including those for which voting rights have been suspended.
2 The total number of exercisable at a shareholders’ meeting (or “net”) voting rights is calculated without taking into account shares for which voting rights have been suspended as shares held in treasury by the Company. It is released in order to ensure that the public is properly informed.
