These provisions include income taxes for Peru, Mexico and the United States. The Mexican royalty, the Peruvian royalty and the Peruvian special mining tax are included in the income tax provision. The decrease in the effective income tax rate in 2021, compared to the same period in 2020 was primarily attributable to a movement in exchange gains and losses from the strong depreciation of the Mexican peso against the U.S. dollar in 2020.

Peruvian royalty and special mining tax: The Company has accrued $21.3 million and $9.3 million of royalty charge in the first quarter of 2021 and 2020, respectively, of which $11.6 million and $2.0 million were included in income taxes in 2021 and 2020, respectively.

The Company has accrued $21.2 million and $4.2 million of special mining tax as part of the income tax provision for the first quarter of 2021 and 2020, respectively.

Mexican mining royalty: The Company has accrued $47.4 million and $8.1 million of royalty taxes as part of the income tax provision for the first quarter of 2021 and 2020, respectively.

Accounting for uncertainty in income taxes: In the first quarter of 2021, there were no changes in the Company’s uncertain tax positions.
