for this afternoon's conversation









Rob, here is what I want to chat about this afternoon.  What I would
like to do is walk thru these tables to see what your expectations are. 
These tables reflect no final decisions on our part, it only reflects my
understanding of your conversation with Bryan.   Talk to you after 2:00.

The purpose of this table is to understand what cost/benefit comparisons
will be made in the RIA.  Inherently, this table assumes that we are
comparing the “matched” costs and benefits in terms of scope as
appropriate (i.e. only benefits derived from modeled controls would be
compared to the modeled controls).  Based on your conversation with
Bryan, this is what we think you are expecting.

Cost/benefit comparison table

	Engineering Cost	Social Cost

Modeled controls  “A”	RIA body	appendix

Extrapolated Cost “B”	RIA body	appendix

Sum  “A + B” (in cost/benefit chapter)	RIA body	appendix

In Executive Summary	Yes (???Separately or just as a Sum of A+B???)	No



As a logical predecessor to the presentation of the cost/benefit
comparison, there is the question of where the cost estimates themselves
are presented.  It is not clear of your thoughts on this.  Taking the
cue from the table above, we show the same pattern in the table below
for the presentation of the costs
