faux logic. we need the cash NOW, not in 2018.
if we have cash left over in 2018, we can buy biogen stock or exxon stock if you want to collect dividends...except that Biogen doesn't pay a dividend....
and the cash flow from royalties comes whether or not we take stock or cash up front.
Any acquirer could sell the Biogen stock, so there is no deterrence value.
And it is not a stock swap, if biogen isnt getting AVXL stock, it is a payment in stock.
Makes zero difference whether we get paid in $$, Euros, Bitcoins, Exxon, GM or Biogen stock.
