But can I just make a couple of other points, and I make them just so that we can keep these arguments in perspective. I think that the extra costs which restaurants would have to bear during the coming year represent somewhere between 0.1 and 0.2 of their overall costs and I very much doubt whether an increase of that proportion is going to topple a business from profit into insolvency. The costs aren't I think as great as some of the others which the restaurant trade has to bear.
Secondly, of course one of the things that one hopes will follow from the polluter pays principle is the introduction by individuals and by commercial interests of the technology or the practices which will limit the amount of pollution which they themselves produce. It's clearly easier to see that done when you're talking about a large firm or a large manufacturing plant but there are also things which smaller polluters can do to limit the pollution and to limit the charge on them.
Mr Henry Tang (in Chinese): A very short follow-up please. Previously I was at the Labour Advisory Board for nine years and I do know that the Government is very good with figures in trying to sell something. If they want you to accept a point then they will give you statistics to show you that it's cheap, it's acceptable. So Mr Governor, when you talk about 0.1 or 0.2% increase, I hope that Mr Governor, you will be more careful with the way you interpret the statistics.
Now as for the survey that you mentioned, when will that be completed?
Governor: It will be completed later this year and as for the question of statistics, it's not only Governments which understandably lean on the statistics which they regards as being more central to their case, put it that way. But I think the statistics, the figures that we've given on sewage and the costs of dealing with environmental pollution are accurate. I understand that there are concerns about, not necessarily this year's increase, but the increases which people see in future years if we're to fully recover the cost of the strategic plan within a reasonable time. I understand the concerns about that and I'm sure those concerns will be expressed very vigorously to us during the course of the consultations that we'll be having with the Legislative Council. But if one votes for the polluter pays principle, if one votes for the establishment of a sewage services trading fund, the objective of which is by and large to, if it's not an inappropriate expression in the circumstances, wash it's own face financially within a given period of time, then one somehow has to make the figures add up. Those are the statistics which are really awkward in these circumstances but those are the statistics that we're all left with at the end of the day.
