I guess the saying is that Elephants don't forget. I've said it before that the timing of the release was not good and will never discount that.
However, even though you did not physically receive shares if in fact you still hold shares of HEMP you technically have received them as at least two o the spin-offs have happened and with consideration that HEMP holds the major % of shares in those companies any value whether now realized or potential in the future still would add value to your shares held.
