Hi Hong and Hao, 

Nice talks! I went through the slides posted on Friday’s agenda. I took a look mostly at the numbers. A few questions and comments. 

Hao, add title to slide 4. 

Hong, why is sum of the material on slide 31 not the same as the grand total for material in the BOE page 4? It’s $552,321 (slides) vs $591,011 (BOE), so difference of $40k less on the slides. Is the savings reflecting the changes in the BCPs? The BOE claims to be up to date, but is it? Or am I forgetting something? 

Hao, same question. The sum on your slides is $300,279, in the BOE it is $320,231. The BOE in docdb hasn’t been updated since December? The difference is a savings of $20k. Maybe again it’s the BCPs but the BCPs since December don’t add up to a savings of $20k, rather an increase of about $75k. 

Hao, also in the BCP table, I’m a little confused since the table includes the BCPs for entire DOE scope, not just 6.4.4. It might be nice to break out just the 6.4.4 part in a separate slide, as Hong does. 

Hao, is there a reason you don’t need a traceability slide (Hong’s slide 33)? 

Best, Tim
