[1] Represents VAT that was paid to the Mexican government associated with Coeur Mexicana’s prior royalty agreement with a subsidiary of Franco-Nevada Corporation. The Company continues to pursue recovery from the Mexican government (including through ongoing litigation). See Note 17 -- Commitments and Contingencies for additional detail. The $5.0 million decrease in the six months ended June 30, 2020 is attributable to a weaker Mexican Peso.
