On 10-JAN-2013 Herbalife made a formal press conference issuing rebuttals to Ackman's points. I am working off summary as published on Seeking Alpha so any misinterpretation would be mine, as I'm not working from the source material itself.
Ackman Assertion: There is no R&D spend and Herbalife's products are commodities that sell at high prices.
Herbalife Reply: Dietary supplements are classified as food, not drugs, and thus cannot be expensed as R&D. R&D expense is thus consistent with the peer group of GNC and NBTY.
MY COMMENTARY: Why can't R&D be applied to dietary supplements? This sounds like rather specious reasoning. I need to get to the source material on this. GNC and NBTY manufacture stuff with existing ingredients. Does Herbalife claim any custom formulations with higher effectiveness? If so, then it cannot really be compared with GNC or NBTY, can it?
Herbalife Reply (continued): Further, Herbalife spent $44 million in 2012 on product development, scientific affairs, quality sourcing ("seed to feed" program), product safety, etc. which was not classified as R&D so Ackman missed it.
MY COMMENTARY: Product development is NOT R&D? Quality sourcing and product safety is just QC, isn't it? Can those really be counted as R&D in the first place?
Herbalife Reply (continued): Further, Ackman compared pricing per 200 calorie serving and found the price was almost double the nearest competitors, however pricing should be compared per serving at SRP, and Herbalife is priced right in the median.
MY COMMENTARY: How often is the product actually SOLD at suggested retail price?
