You have to recognize that even in the list we gave you today, these are, in some cases, broad areas that we want to look at. We haven't gone down into the actual scoping of the audit. At times we decide, when we actually do more detailed work, that it's not an area we should look at; we should perhaps be looking at another area. We will change the focus of the audit. It may be the same department or it could actually be another department. Or the timing may not be right; there may be legislative changes coming, or regulations that are going to change, or changes within the department. Any of these could make the timing of the audit not appropriate.
Quite honestly, at times there can be issues with resourcing. We have the skills to do it at a point in time, when initially we planned it, but those people may have left the office, or we may be rebuilding a team. Or we may decide that we are going to shift resources from one area to another area given that something has happened.
Obviously we try to stay as close to these plans as we can, but at times two committee requests will come up. We'll say, yes, we should be doing more work in this area, and we'll move a team from one area to another. The plans will change. Even the list of audits that we are presenting here today--I'm not guaranteeing that those will all be done within the timeframe we've put forward.
