PSA,SMM,and CPR in Level 2 2018?

I was going through some past mocks, and came across a mortgage related vignette related to PSA, SMM, and CPR, but i didn’t come across this at all in the CFA curriculum for 2018. Did I just miss this or has this been taken out of the 2018 curriculum?

PSA is huge!..in 2015.

Long lived assets have been moved to level zero.

MBS seems to be gone from the 2018 Level II curriculum.

Alas.

Had me scared for a sec there, thanks for the responses everyone. Guess that’s the downside going through past mocks…
