"Net operating profit after tax (NOPAT) is a company's potential cash earnings if its capitalization were unleveraged – that is, if it had no debt."

I would go for profit after tax except in the case mentioned above, where NOPAT would be appropriate.

I'd go with this one, I believe...

The term offers a workaround to transphy's objection, since it doesn't necessarily mean "κέρδη". When positive, EAT equal "net profit"; when negative, "net loss".

* In my previous reference it is explained that EAT and net income are more or less interchangeable.

First reference provided should be this one:

not the greek one

Greek term (edited): αποτελέσματα περιόδου μετά από φόρους

Σπύρο, ζητάς 'αποτελέσματα περιόδου....' και όχι 'εισοδήματα' όπως λες πιο πάνω εσύ; it can be 'income after tax', which could be the right term, or even 'profit after tax', again correct. So, which one are you after? you have to adjust your question accordingly.

You suggested 'income after tax' =εισόδημα .....
and 'profit after tax' =κέρδος....
Και τα 2 είναι ορθά, άλλο όμως το 'αποτελέσματα' άλλο το εισόδημα' και άλλο το 'κέρδος'.
