Equity: Clean surplus violation: nonrecurring items 618, why, already, through, adjust

mar350

for RI model, does non-recurring items already reflected in the equity or not? why we don’t need to adjust B/S? Thanks.
book 618 as I read through it, I don’t get the idea… Thanks.

for RI model to work, the clean surplus must not be violated.
clean surplus is B(t)=B(t-1)+E(t)-D(t) where E(t)=(ROE-r)*B(t-1)
The idea is that if you have nonrecurring items on the IS that alter B(t) by an amount different that E(t)-D(t) then you CANNOT use the RI model. Said another way, for the RI model to be a valid, book value should only increase by E(t)-D(t).
Hope this helps.
