In this case, I think it's more appropriate that I respond, because this was a policy decision on what the appropriate rate was, and that policy decision was based more on whether it would be break-even--exactly break-even, or approximately. There were three factors that we took into consideration. One was that we wanted this to be principles-based; second, we wanted it to be administratively simple; and third, we wanted it to be fair for both those who would be signing up for this, i.e., the self-employed, and for other ratepayers. So it was a broader set of considerations.
I'd be happy to elaborate on those principles and administrative ease, if you'd like.
