SS15 - Using Swaps to Create & Manage the Risk of Structure Notes

Just curious how much weight people are putting on Section 2.3 (page 450). It isn’t addressed specifically in the LOS however it isn’t marked with an optional section either. I think the laziness factor is kicking in here, I know its only 5 pages… Anyone come across any reference to structured notes (leveraged/inverse floaters, etc.) in any of the past exams?
