Subject: RE: Questions on RCW Manufacturing Cost and Efficiency Submittals

Judy,

I have had a chance to go through your questions and will try to answer:

1. The original aggregated incremental cost data I sent you had the numbers truncated,

which suggested that the min and max were outside of the average for the additional

calculations (Table B

‐ 2). I have taken all costs, for all tables, out to 2 decimal places.

Modified tables are attached.

2. As far as I know, the incremental costs are all relative to the baseline. These are the

instructions provided to us and what we provide to our members.

3. On the market share efficiency data, the levels correspond to those in the data

collection request. I have modified our submission to include the levels, to reduce

confusion. I have also split out the top and front load tables for clarity. I provided data

for the six levels listed in Table A

‐ 3 of the data collection request, with maximum values

at 2.25/4.45 for Top load and 2.89/3.36 for Front load. Updated tables are attached;

however, values have not changed.

If you have any additional questions, please let me know.

Best regards,

Debra
