Sure, my first post to Dew I wrote about the need to raise money this year. PDUFA will be 2019. Discount back my guess for 2 years and subtract out another discount for offering and you will be in the high 3's. And it could get into the 4 handle before it happens. All wild guesses for discount rate and end valuation at this point. I assumed $120M valuation post pdufa.
