Contingencies Brazilian Tax Issue From 2002 to 2007, the Company’s Brazilian subsidiary imported goods through, and paid taxes on such imports to, the State of Espirito Santo in Brazil. Upon the final sale of these goods, the Company’s Brazilian subsidiary collected taxes from customers and remitted them to the State of Rio de Janeiro net of the taxes paid on importation of those goods to the State of Espirito Santo in accordance with the Company’s understanding of Brazilian tax laws. In December 2010 and January 2011, the Company’s Brazilian subsidiary was served with two assessments totaling approximately $13.0 million from the State of Rio de Janeiro to cancel the credits associated with the tax payments to the State of Espirito Santo on the importation of goods from July 2005 to October 2007. The Company's Brazilian subsidiary objected to these assessments and filed appeals with a State of Rio de Janeiro judicial court to annul both of these tax assessments. In the first quarter of 2021, the relevant governmental agencies of the State of Rio de Janeiro authorized an amnesty program with interest discounts and reduced fines. The Company’s Brazilian subsidiary elected to participate in this amnesty program and recorded the settlement amount of approximately $2.1 million as of March 31, 2021. As a result of settling these tax assessments with the relevant governmental agencies pursuant to the amnesty program, the security amounts previously deposited with the court totaling approximately $6 million at current exchange rates were returned to our Brazilian subsidiary during the second and third quarter of 2021.
