Note 18. - Income Tax

The effective tax rate for the periods presented has been established based on Management’s best estimates, taking into account the tax treatment of permanent differences and tax credits.

For the three-month period ended March 31, 2021, income tax amounted to a $14,487 thousand expense with respect to a profit before income tax of $2,943 thousand. In the three-month period ended March 31, 2020, income tax amounted to a $10,147 thousand income with respect to a loss before income tax of $48,412 thousand. The effective tax rate differs from the nominal tax rate mainly due to permanent differences and treatment of tax credits in some jurisdictions.
