Interest on these non-voting participating securities comprises a fixed portion of 7.5% paid per year applicable to 60% of the nominal amount of the security, and a variable portion applicable to the remaining 40% of the nominal amount of the participating security, which is linked to consolidated net profit (loss) for the previous year and to the reference six-month Libor EUR rate +7/8%. The amount paid per security in 2021 was €61.3, paid in two installments (€27.95 and €33.35). In accordance with the decisions approved by the General Meeting of the holders of those non-voting participating securities on November 19, 2020 and in the context of the end of the publication of the LIBOR rates as of December 31, 2021, the EUR 6-month LIBOR reference rate of +7/8% per annum used for the calculation of the variable portion of the compensation of the security is replaced, as from the date of the opening of the period of compensation i.e. February 11, 2021, by the 6-month EURIBOR rate of +7/8% per annum .

A certain number of those securities have been repurchased over the years. At December 31, 2021, 77,516 securities were outstanding with an aggregate face value of €77.5 million.
