The following table provides an analysis of financial instruments measured at fair value, grouped into levels based on the

degree to which the fair value is observable:

•Level 1 is based on a quoted price (unadjusted) in active markets for identical financial instruments. Level 1

includes aluminum, copper and zinc futures that are traded on the LME.

•Level 2 is based on inputs other than quoted prices included within Level 1 that are observable for the assets or

liabilities, either directly (i.e., prices), or indirectly (i.e., derived from prices). Level 2 includes foreign exchange

derivatives, natural gas derivatives, silver derivatives and aluminum premium derivatives. The present value of

future cash flows based on the forward or on the spot exchange rates at the balance sheet date is used to value

foreign exchange derivatives.

•Level 3 is based on inputs for the asset or liability that are not based on observable market data (unobservable

inputs). Trade receivables are classified as a Level 3 measurement under the fair value hierarchy.



	At September 30, 2026				At December 31, 2025
