When I refer to the 18 months, I'm referring really from the point in time that we have decided we're going to do an audit and we start the actual planning of that audit, until the time we report on it. So as opposed to our planning going out where we're saying, okay, next year we're going to do an audit on this and in two years time, we'll do an audit on that. The 18 months is very much about how long it takes us to execute an audit from, okay, we have started, we're starting the planning, we go through the planning phase, we get to the execution phase, and then we get into the reporting phase.
In terms of the audit of senators' expenses that is under way right now, we originally were estimating that we would be operating under that similar timeframe. It has turned out, as I said last week, our plan is to provide that report to the Speaker of the Senate the first week of June. So that will have been about a two-year timeframe, a 24-month timeframe from the point in time we started until we deliver the report.
