But Im no accountant.
Nor am I. But I'm going to guess that there is a difference here between actual cash flow and accounting for earnings purposes.
I think many people outside the industry, do not understand how greatly cost have risen for an increases in domestic oil production.
In many cases, it is the subscontractors and equipment/material suppliers that are seeing higher profits than the actual oil production companies.
On the debt/tax, I was only guessing. I don’t know, but a tax rate over 100% makes even less sense.
