Exxon Mobil Corp. was ordered Monday, June 15, 2009 to pay about $500 million in interest on punitive damages for the Exxon Valdez oil spill off Alaska, nearly doubling the payout to Alaska Natives, fishermen, business owners and others harmed by the 1989 disaster. The ruling was issued by the 9th U.S. Circuit Court of Appeals in San Francisco. Nearly 25 years after the Exxon Valdez oil spill off the coast of Alaska, some damage heals, some effects linger in Prince William Sound. (AP Photo/Jack Smith, File)
