"Consider the situation faced by the CFO of a company with a market capitalization of $$500$ Millions of USD, e$.$g$.$ the firm has $25$ million shares outstanding, so the shares are trading at $$20$ per share. The CFO needs to raise $$200$ Millions of USDs and announces a rights issue. Each existing shareholder is sent $6$ right for every share he or she owns. The CFO has not decided how many rights will be required to purchase a share of new stock. At the current price per share, what is the maximum amount of rights the CFO can require stockholders for purchasing a share of new stock and so be able to raise the $$200$ Millions of USDs?"
