Mismanaged utility over the years. One I was quite bullish on it and actually owned it but sold once I started to see some signs the dividend was deteriorating.
I just think there are numerous better regulated utilities out there to own, especially considering the company sold off most of its renewable assets to shore up the balance sheet. It is now practically a regulated utility, and in my opinion one that is inferior to Fortis, so I've never considered owning it again.
