Derivative financial instruments classified as Level 3:

The fair valuation of Level 3 derivative instruments is established at each reporting date and compared to the prior period. ArcelorMittal’s valuation policies for Level 3 derivatives are an integral part of its internal control procedures and have been reviewed and approved according to the Company’s principles for establishing such procedures. In particular, such procedures address the accuracy and reliability of input data, the accuracy of the valuation model and the knowledge of the staff performing the valuations.

Electricity option

ArcelorMittal and an electricity supplier entered into a multibuyer power supply contract on French market. Other clients of this contract are committed to purchase electricity from the supplier with opt-out rights to be exercised in 2029 for 2030-2034 delivery period. The Company is committed to acquire up to 51% of the opt-out volumes.

The fair value of the option is based on the Black-Scholes model using a Monte Carlo numerical calculation approach. Observable input data used in the valuation include euro zero coupon yield curve and electricity forward prices for tenors quoted by the European Energy Exchange (EEX). Unobservable input data is used to measure fair value to the extent relevant observable inputs are not available. For instance, electricity forward prices
