Suppose that EBV makes a $$6$M Series A investment in Newco for $1$M shares at $$6$ per share.One year later, Newco has fallen on hard times and receives a $$10$M Series B financing from Talltree for $2$M shares at $$5$ per share. The founders and the stock pool have claims on $3$M shares of common stock.Consider the following cases:Case I: Series A has no antidilution protection.Case II: Series A has full ratchet antidilution protection.For each of these cases, what percentage of Newco $($fully diluted$)$ would be controlled by EBV following the Series B investment? What would be the post$-$money and pre$-$money valuations?
