Ann: 2014 Annual Report to Shareholders, page-30

Big mak,
sorry, facts are often difficult to understand and retain, particularly if they are unpleasant.
look at performance, look at cost overruns, look at lack of pressure data, look at well performance.
compare this to normal performance data. Don't forget schedules and milestones missed. Look at cr timings, look at your investment values.
if you need it spelt out, move your investment portfolio to something less technical, like coca cola or Kellogg's corn flakes.
