BP damage Claim

Bp has set aside 20 billion dollars to settle any claims due to damages caused by the oil leak, with millions of business that are affected, many fisher men, lobster fishing farmers, cruise boats etc, many of these businesses are loosing thousands of money daily when they are not operating, they have equipment rent expenses, they are purchased goods are rendered useless, no income to pay employees, loss of jobs etc. Will the  20 billion compensation funds be enough to cover all damage expenses? last report about the business affected on cnbc news station has reported that many of these businesses that filled claims are not satisfied as Bp was unable to grant them enough funds to cover the debt they have acquired.
