But if they have high confidence of being sole generic...
This is the most common sentiment on every message board when a company decides to raise money. The logic is the same in all circumstances: if the company were confident about trial result, they wouldn't have raised money; if the company were confident about FDA approval, they wouldn't have raised money; if the company were confident about xxxx..... The fact is no matter how confident the company is about anything, they can't be 100% sure about these things. It's about managing risk. Even if you are sure about something 90% - not many things in biotech come close to 90% sure thing IMO - you still have to manage the 10% risk. It's called prudence, for a company or for individual.
