The book McKinsey’s Valuation defines NOPLAT/NOPAT as EBITA - actual taxes. It then uses NOPLAT/NOPAT to calculate FCF & ROIC.
Mauboussin’s book Expectations Investing calculates NOPLAT/NOPAT as EBITA - actual taxes.
Damodaran’s book Investment Valuation however defines it as EBIT - actual taxes.
Why this inconsistency between 3 well respected books?
