22. Income Taxes (continued) c) Deferred Tax Assets and Liabilities Not Recognized We have not recognized $299 million (2021 – $293 million) of deferred tax assets associated with unused tax credits and tax pools in entities and jurisdictions that do not have established sources of taxable income. Deferred tax liabilities of approximately $858 million (2021 – $803 million) have not been recognized on the unremitted foreign earnings associated with investments in subsidiaries and interests in joint arrangements where we control the timing of the reversal of the temporary differences and it is probable that such differences will not reverse in the foreseeable future. d) Loss Carryforwards At December 31, 2022, we had $166 million Canadian net operating loss carryforwards (2021 – $1.16 billion) and $1.22 billion (2021 – $972 million) of Chilean net operating losses, which have an indefinite carryforward period. The deferred tax benefit of these pools has been recognized. e) Scope of Antamina’s Peruvian Tax Stability Agreement The Peruvian tax authority, La Superintendencia Nacional de Aduanas y de Administración Tributaria (SUNAT), issued income tax assessments for the 2013 to 2016 taxation years to Antamina (our joint operation in which we own a 22.5% share), denying accelerated depreciation claimed by Antamina in respect of a mill expansion and other assets, on the basis that the expansion was not covered by Antamina’s tax stability agreement. Antamina objected to the assessments, but lost its administrative appeal with SUNAT. In 2022, the Peruvian Tax Court issued its ruling in favour of SUNAT on this matter for the 2013 taxation year and rejected Antamina’s request for a full waiver of the associated penalties and interest for that year. Antamina is continuing to pursue the matter in the Peruvian Judiciary Courts. The denial of accelerated depreciation claimed is a timing issue in our tax provision, which we have already recorded in a prior year. In light of the recent Peruvian Tax Court ruling, we have expensed our share of previously paid interest and penalties for the 2013 to 2016 years as reflected in finance expense and other non-operating expense.
