Disclosure of entity's operating segments [Abstract]

The Company is organized in two operating segments: Steel and Mining.

The Steel segment includes the sales of steel products, which comprises mainly slabs, hot and cold rolled products, coated products, roll-formed and tubular products, billets, bars and other products.

The Mining segment includes the sales of mining products, mainly iron ore and pellets, and comprises the mining activities of Las Encinas, an iron ore mining company in which Ternium holds a 100% equity interest and the 50% of the operations and results performed by Peña Colorada, another iron ore mining company in which Ternium maintains that same percentage over its equity interest.

Ternium’s Chief Executive Officer (“CEO”) functions as the Company’s Chief Operating Decision Maker (“CODM”). The various geographic regions operate as an integrated steel producer. The CEO allocates resources and assesses performance of the Steel Segment as an integrated business and of the Mining Segment. The CEO uses “Operating income – Management view” as per the below table as the performance measure which differs from operating income determined in accordance with IFRS principally as follows:

•The use of direct cost methodology to calculate the inventories, while under IFRS is at full cost, including absorption of production overheads and depreciation.

•The use of costs based on previously internally defined cost estimates, while, under IFRS, costs are calculated at historical cost (with the FIFO method).

•Other non-significant differences.
