The Globe and Mail reports in its Wednesday edition that billions of dollars in Canadian capital gains taxes from the proposed sale of Teck to Anglo American PLC could be deferred for up to 15 years because of how the deal is structured. The Globe's Jameson Berkow writes London-based Anglo has announced plans to acquire Teck in an entirely stock-based transaction that would create one of the world's largest copper producers, with a market value of roughly $50-billion (U.S.). Instead of receiving shares of the British parent company, however, Canadian shareholders of Teck can opt to receive shares in a new Canadian subsidiary that will trade on the Toronto Stock Exchange. The option has a clear tax benefit. Even though the combined company -- set to be called Anglo Teck -- will be headquartered in Canada, its primary public listing will be on the London Stock Exchange. If Teck's Canadian shareholders were to exchange their TSX-traded shares in Teck directly for LSE-traded shares of the new company, Canadian federal rules would consider that a sale, which is immediately subject to capital-gains tax. If shareholders instead receive shares in a Canadian-based company, capital-gains taxes are not immediately triggered.
