Let me focus on the sustainability question. I think it all turns on the point that we weren't interested in seeing a business that we couldn't get adequate returns on—i.e., not a bailout. So if we looked at the plan and looked down the track and asked if this is a business we can sustain if we do invest, I think there was significant concern given the industry structure, given the scale, the migration, and some new technologies. It really turned on sustainability.
