Mock Exam #32: how long is medium term

Does anyone know where in the books it explains what is medium and what is long term? This one we had to pick a benchmark, endowment described itself as medium term term horizon which I though was 7-10 years.

hmm whats the question? medium term is 3-10 AFAIK, everything > 10 long term. I even saw it in CFAI books somewhere

i guess i should have gone by description as “long” oh well.

0-5 st 5-15 intermediate 15+ long term
