Reclassification of currency translation adjustment reserve: During 2022, as result of NKKTubes’ definitive cease of operations, the currency translation adjustment reserve belonging to the shareholders was reclassified to the income statement. For more information see note 36.

Tax recovery in Brazilian subsidiaries: On May 13, 2021, the Brazilian Supreme Court issued a final judgment confirming that in calculating PIS and COFINS (Federal Social Contributions on Gross Revenues), tax payers should exclude from its base the total output of ICMS, calculated on a gross basis. This decision led to a recognition of approximately $53 million tax credit in Brazilian subsidiaries, out of which $36 million were recognized in other operating income and $17 million in financial results (impacting in Finance Income and Finance Cost). In addition the tax charge related to this gain amounted to $12 million.
