Intrinsic P/E vs Justified P/E

I bring this question up in response to CFAI 2011 PM Mock #57. In the book, they talked about justified P/E alot and importantly, always specified trailing or leading P/E. In this question they ask for the intrinsic P/E and do not specify. In the explanation they use the same equation as for justified forward P/E. (1-b)/(r-g)

Does anyone know what the distinction is between justified and intrinsic or if we should assume forward P/E when it’s not specified?

Thank you

I think intrinsic and justified are the same thing. Its what the multiple should be based on fundamentals (payout ratio, required return, growth rate).

I don’t know about the forward / leading PE, they ought to specify it I think …

Agreed. I was co confused by that lack of information. They presume we ought to know what they mean, n u have to try in two cases to see what matches their answers.
