things Schweser missed

This is the first time I find something that Schweser did not cover. Adjusting for free floating shares in reading 36. But then again, no CFAI LOS asks you to do it. So why is CFAI teaching it? What do you guys do with such stuff. Do you study it. Anyone who knows of something Schweser did not cover please post here for those of us not reading the CFAI curriculum (or read it and forgot). Thanks!

^^ Great idea for a thread
