I think it was just a mis match of supply demand that happened in a very short period of time, and we just opted not to turn off some of the pipes as quickly as we could have. We were pretty transparent at that's what happened. And our price discovery process isn't fast enough to get prices where supply meets demandd when we had that disequilibria. So really, it was just sometimes you don't know if something is momentary and it's going to clear itself up in a few days,. or whether there's something deeper going on in the economy of whatever.
