(1)The carrying amount of short-term financial assets and liabilities at amortized cost is considered a reasonable estimate of fair value, in accordance with IFRS 7.29.
(2)The fair value of long-term deposit accounts is determined using a discounted cash flow model based on the contractual reimbursement amount and the estimated market discount rate applicable, therefore classified within level 3 IFRS 13 fair value hierarchy.
(3)The carrying amount of cash and cash equivalents is based on level 1 valuation and corresponds to the fair value of the assets.
(4)The fair value of royalty certificates, the Lenders’ Tranche A and the Lenders’ Tranche B, accounted for at amortized cost, is determined using level 3 valuation based on unobservable inputs, as described in Note 4.9 – Debt, derivatives and royalty certificates liabilities.
(5)The classification of other bank borrowings within the IFRS 13 fair value hierarchy corresponds to a level 3 valuation.
(6)The fair value of derivative instruments, including the conversion option embedded in the Convertible Bonds, the Lenders’ Warrants, is determined using valuation techniques based on significant unobservable inputs and is therefore classified within Level 3 of the IFRS 13 fair value hierarchy. Further information is provided in Note 4.9 – Debt, derivatives and royalty certificates liabilities.
