This has been discussed from time to time. What I like about it is the possibility of extra-clinical applications (firefighters, smoke jumpers, infantry) where a lot of product would be deployed but for the most part eventually discarded on expiration date. The dates might have to be set conservatively due to necessarily suboptimal conditions of storage for at least part of the period deployed, so that replenishment might generate considerable annual demand. It would be interesting to know how the shelf life depends on the shelf environment.
It is unfortunate that any potential for GTC must be weighed against how many shares they will sell to get there. The company, again - unfortunately, turned into a printing press since 2005 and I see no evidence of that changing.
Such a shame. They get nervous by a single downtick and ruin their share structure as if it meant nothing.
