A) There is no indication that the company has increased the outstanding shares (or float) as a result of increasing the Authorized shares. I assume the Outstanding was getting close to the Authorized - but it may just be to clear up what the authorized is as the Q3 report contradicted the filings and to save money they bumped iot to a number they will never need.
B) Companies need money to expand and grow - especially when you are breaking out - German packaging for instance needed setting up and produced. Studies need funding, marketing campaigns need funding. May be they found an investor to lend them on better terms than IBEX due to the success they are now having. c) It will all be moot once the FDA clearance comes and Walgreen's puts up $50m+ for US licencing rights
