The other thing to remember is that the market currently is oversupplied; so there is actually a stockpile, an excess of units in the market in totality. We actually made a decision quite early on—because there was an argument to say, "Well, why would you auction any units into an oversupplied market at all? Why not just allow the stockpile to run down and then start auctioning into the system once the stockpile has run down?" We decided that what we would do is to auction, frankly, a fairly small amount of units on an ongoing basis to get that system up and running and run the stockpile down over a period of time at the same time, so that, by the time the stockpile does expire, there's a long experience of auctioning units into the system.
