It's a difficult question, and I'll try to not give you a lecture and not answer the question.
Our problem is that we have a very large system that involves many people. It will never be perfect, so we set standards. We have a set of values. We will have cases where things are not perfect. Our job is to identify the things that are perfect and try to get correction and take corrective action.
You'll see in the reports that on the one hand we flag those things that were not done correctly that we want done better--specific transactions. We'll also go after systems issues. But overall my conclusion is that the system is really quite robust--perfect, no; there are issues we have to work on, absolutely, and there are some warning signs, yes. But do I have fundamental worries about the system? I would say no at this point.
