Thanks for the reply;
The point is I am trying to get a handle on the immediate supply of stock that actually is available to the public, I think it is about 40M, I see that the Class B is convertible either by writing the Corp or automatically by 2027. These numbers are messing with my brain.
It is confusing, the Class B stock is convertible to what I'll call trading stock, but until it is converted, the trading stock for any day is the Class A stock.
A 16M trading day would be more important if the stock available is 40M than if it was 228M.
Anyhow, thanks for the links, very helpful.
