Yes, that was a decision that was entirely related to how best to manage our balance sheet in a way that doesn't impede the performance of a major core funding market, which is the Government of Canada market.
Because of the size of the debt outstanding—that's either treasury bills or government bonds that are issued—and the needs of our balance sheet, we were taking up more and more of the bonds in the primary market. Because of that, we were not leaving enough for the private sector, which actually needs those bonds, so in our balance sheet management, we look at what other obligations that don't put the Bank of Canada's balance sheet at risk are suitable for balance sheet purposes. That was one asset that we considered a while ago and decided to start purchasing. It has nothing to do with anything other than that, including the state of the housing market.
