With respect to bankers' acceptances, again this was set up early on when markets were not functioning very well and we agreed to purchase a certain amount per week of bankers acceptances. Right now, we have only $3.7 billion on our balance sheet. Many of our purchases have matured and peaked at around $47 billion.
The reason we don't have many more left is that they've matured and markets aren't interested in providing us with any. When we go out every week to buy a certain amount, they're not being offered, because the market is working extremely well. That's why, as Governor Macklem said earlier, we've been able to scale back some of these programs, including the bankers' acceptance program, as market conditions have improved.
