Okay, thank you. I'd be pleased to answer that question.
I think we engage with companies in three ways. We talked about proxy voting. I think the most powerful one has to do with coalitions of other investors. We also do direct engagement with companies. With regard to mining companies, if there is an engagement with a company that is ongoing, while that discussion is ongoing we don't disclose the nature of that conversation. But if it is not going the way we would want it, we reserve the right to do that. There are a number of instances when we have disclosed those letters with some Canadian mining companies. We could share those with the committee.
