Hi folks! The net debt/ebitda had a significant increase. We can see also the net income decreasing substantially. Can we attribute this fact, mostly, to the price of oil in 2020? Can anyone explain a little more about that? I see that part of the net debt/ebita was increased because the lower ebitda. Anyway, we can see the increasing debt of the company. Should we be concerned about the net debt/ebitda, and the decreased net income, or this is mainly consequence of the oil prices in 2020?
