They are (about 35% of the total), but the MDVN balance sheet in general, i.e. far more cash, far less debt, etc. was much healthier and valuable. Ariad's sucks. Contribution by the BoD is they permitted HB to squander one or two hundred $million on the proprietary font.
The BoD overpaid themselves and the CEO, they breached their fiduciary responsibilities, they doctored their records and coerced and bought off their accuser...I want THE TRUTH!!!
