These are not facts, they are your forecasts for future events. There are an infinite number of other scenarios that might play out. My forecast is that your numbers are wildly on the high side. You also ignore the time value of money. Even if someone is out of work ten years, no court would award him ten years of salary today, they would discount it to reflect time value of money. You also ignore that BP generates some $30-$40 billion a year in cash from operations. All in all, not a convincing analysis.
