First of all, the mandate of the bank is not changing. But to give you the context for this, last August the subprime issue raised its ugly head, and it became apparent fairly quickly that some of the central banks had more room to move than did other central banks. That included a need to expand the options that the Bank of Canada has. That's why we've gone ahead in this bill and seem to have expanded the types of securities that they can take.
You've seen some of the announcements about that by the bank in recent times as well. Mr. Rudin can reply with respect to the specific instruments.
