Q: A comment on Roland's question:
The Netherlands listing (UN) is subject to a 15% withholding tax on the dividends, whereas the UK listing (UL) has no such withholding tax. For a taxable account, this doesn't make any difference, since the 15% can be deducted from the Canadian tax ultimately payable. However, for an RRSP account, this 15% tax is irretrievably lost, effectively reducing the dividend you receive by 15%.
Hence, I would recommend buying only the UL listing for RRSP accounts.
