Same explanation that you guys didn’t want to hear about before. There are earnings reporting difference between US and the rest of the world. Most of the trading companies you reference are able to report their earnings using the non-US method.
House analogy again….
US: Asks you to report the debt from the mortgage but they don’t care about the value of the house until you sell it. You look like you are in debt until the house is sold.
Rest of world: Doesn’t require that you report the value of the mortgage until the house is sold. Only then do you report the two, as a netted value.
House = oil. Mortgage = derivatives.
