I don't have any insights. Since everyone seems to be getting different % of what they requested. I was going to guess that it would be 18.74% of their existing holdings because $200,000,000/$1.8 is 111111111 shares which is about 18.74% of 592,903,820 the current number of shares issued.
But I guess it is some other formula that takes into account both existing holding and application requested. Since if you got less than 18.74% of your existing holding then that would suggest others got more than 18.74% of their existing holdings.
