(a)Includes derivative financial instruments: €121 million as of December 31, 2024, €164 million as of December 31, 2023, €232 million as of December 31, 2022. The figure as of December 31, 2024 includes €2,007 million for the liability in respect of royalties payable to Sobi on net sales of Beyfortus (nirsevimab) in the United States (see Note C.2.). Given the method used to calculate royalties payable, an increase or decrease in sales forecasts would lead to a proportionate change in the amount of the liability. The nominal value of payments estimated to be due within more than one year but less than five years is €1,140 million; the nominal value of payments estimated to be due after more than five years is €2,792 million.
