OPHI's predecessor Stock -- AMSZ -- did a R/S in late-December 2010 / early-January 2011.
As I best recall, it was a 1:50 R/S.
And then, OPHI -- an entirely different (and BETTER!) Company, engaged in an entirely different industry -- took over the reins, in a complex transition and transaction.
I know -- I've been in this since late-2009. Feeling MUCH BETTER ABOUT THINGS, nowadays!$$
