Ann: Successful Efforts Accounting and write down of Inventories, page-4

Thanks buddy. This is what I try to confirm "Its unclear as to the extent any losses could be offset against future profits to reduce future tax payable because that depends on the rules and the country in which the losses happened". I am very amateur in accounting and taxation and believe you are someone that I can look up to. I learn all the way. So very much appreciate kind person like you.

Yes, fossil fuel industry is not easy to play nowadays. But these beaten up business look like have been over beaten. Cheers
