Residual Income - Trickier than expected

Residual Income looks easy but the questions are pretty tricky. Only after failing one whole set, I understood RI about persistent factors, ROE and RI relations closely

Did RI in corporate finance, but I don’t recall anything on persistent factors, ROE and RI relations!

equity section… not the corp fin part.

RI is present in a small section in Corp Finance as well; under dividends

in corp its the residual dividend method, which is diff than using RI as a valuation model
