That's something we need to get to the bottom of. We have undertaken already an effort to look back at apps that would have had access to that level of data prior to locking down our platform in 2014. We're in the process of doing that. We don't have firm answers on exactly what the scale of the problem is at this point, but it's something that we do need to undertake and that we're working to do expeditiously.
In addition to looking backward, we have an obligation to look forward, and that involves really three things. The first thing is making sure we are locking down the information that is available, so going forward, the type of information that was available previously won't be available.
The second thing is, for the limited information that is available, we need to make sure we're exercising effective oversight and that we're understanding who has that information and what they're doing with it.
The third thing, as we've talked about earlier today, is communication. We need to commit, and we have committed, to communicating much more quickly and much more practically with people when these situations arise.
