Fvpl fvoci

Early in Volume 2 we are told that as of 2018 designations of FVPL and FVOCI will replace things like available for sale, but later on the book repeatedly mentions held to maturity, available for sale etc. as important distinctions? FVPL and FVOCI are not mentioned again (at least not to page 300 of volume 2, where I am right now).

I must be missing something. Can someone please explain?

FVPL and FVOCI are IFRS related. The other designations are GAAP related.
