I can only explain my guess, not the PPS.
As so many others here have pointed out, OS on 3/20 was 3.8 billion shares. GGI had almost 10% of those, which would have to be disposed of before GZ could get more money.
Assuming they did this on the run past 2c, then GZ would be able to issue about 400M more shares to GGI for more funds. That puts OS to about 4.2B. To be on the safe side, I say 4.5B.
But hey, that SB2 was adjusted way back in January. What if it still needed SEC approval? Then forget about that scenerio where GZ could pull more money from GGI. OS stays at 3.8 billion. I can handle that.
But what if GZFX sold shares straight to market themselves on that runnup? I don't even know if they can do this, but what if they did. What if they sold 1 billion shares for 1.5c? New OS is 4.8, but GZ has a cool $15M in the bank. Good job I say.
All in my very humble opinion.
