If amarin needs cash down the road it can pull a few levers :
1) sell worldwide rights of Vascepa ex-US, ex-Japan (probably worth the current market cap)
2) license Vascepa to Pfizer, AZN, Merck, Lily, etc for combo (each company pay just $250MM and you get the current market cap)
3) sell the company @ $15/sh if the Vascepa launch do not live up to expectation, ala HGSI.
