The challenge is getting appropriate data. That's the challenge we always face in any cost estimate. The process is bringing ourselves up to speed on the situation. This is a new area for us, so we've been busily reading background materials. Then we would reach out to our network that we built up over the years to understand what data exists, and sometimes the data is not very good. We look at how that compares to our particular situation. There's a bit of judgment and experience involved in making sure the data that we are using to benchmark with is relevant to the study that we're doing. The biggest challenge is finding it and then making sure it's comparable.
