intercorporate investments, Q please

CFA Level II
#1

I have a q on intercorporate investments, for the acquisition method, schweser says stockholders equity stays the same, but q #3 in CFA says that under the acquisition method that SHE is highest because it includes minority interest, So what is correct?

#2

there is an entire errata on this, acquisition is highest and equity/proport consolidation is roughly equal

#3

is that a correction to schweser or to CFAI materia?

#4

schweser
