is NOPAT = EBIT(1- TAX RATE) ?

CFA Level I FRA
#1

Is EBIT equal to operating income??

And am I correct if I assume that EBIT is non - GAAP measure?

#2

As far as I know, operating income is commonly equal to EBIT.

So Net Operating Income is also EBIT. Hence, NOPAT would be EBIT after tax.

Not much problem.
