In the document we bring to your attention today, we're just saying that the Bank of England is doing interesting things and that we could inspire ourselves from their example. By buying commercial paper—ABCP paper as well as mid-term notes—directly in the market, we think the government could help bring liquidity, because the investors are nervous to be stuck with paper that they cannot sell if they need liquidity. If the government were there, it would help; it would bring confidence that those investors could sell the paper when they needed to.
This is one of the problems we have right now. It's a question of confidence, when the market is losing confidence and you are close to market failure, if not in market failure, and you see it with the decreases in those markets that we have experienced recently.
In terms of exit strategy for the government, the government, like any normal player, could sell that paper when the market is better and confidence is back to normal; that's something important for the government. This is what is interesting. It's not a commitment for years. The government would act just by buying it; the stability comes back, then you can let it go later on—slowly, not all at the same time. That would be the exit strategy.
