The uncertainty about believing that I understand the tax implications and dividend payouts is reason enough for me to put my hands in the air and say "if I don't understand it, I shouldn't invest in it".
I listened for 15 minutes to a TD representative read to me the answers. I didn't believe he understood what he was reading either.
Bottom line, I am not paying an accountant to figure it out for me.
