The sale of most of Falconbridge Dominicana to Swiss company Xstrata has so far not been registered with the Tax Department, despite a 19 July request from the department to Falconbridge. Xstrata bought most of Falconbridge Limited’s outstanding stock for US$20 billion on the Toronto Exchange. The purchase includes 85% of Falconbridge Dominicana. The Tax Department is currently seeking half a billion dollars from the sale of Verizon Dominicana’s assets to a Mexican company.
