In each of our investments, when it reaches the stage of an investment commitment, as this project did, we undertake due diligence. In this case, the due diligence really had two forms.
First, you can imagine in a loan of this size that there's a decent amount of legal work to structure the investment. This is particularly true in a transmission line that goes across international borders. Therefore, we had legal counsel in Canada who were our main counterparts helping us to structure the deal, write the loan agreements, etc., as well as in the U.S. to help us understand how interjurisdictional rules work, tax treatment and that sort of thing. That's the legal support we had, and that's the majority of the due diligence.
The other kind, which is very relevant to Dr. Winfield's comments, was technical due diligence: understanding the impact of the line and the projected flow of electricity in both directions on the line. Now, I will say that the independent system operator did the first and most important part of this work; that is its role. However, we wanted to have an independent view, so we hired consultants, technical advisers who understand electricity markets and have detailed models. They helped model for us how electricity would flow over the line, both trade from Ontario to the U.S. and trade at times when Ontario would need to import, because over the course of the year, electricity would flow both ways on this line. We were modelling those flows.
That's where we spent the due-diligence money. As in any large transaction, I think that's money well spent and taxpayer money well used.
