Credit Opportunities Fund - Case Study

Hello everyone.

I am looking for help on preparation to the case study in a credit opportunities fund.

The fund invests in granular portfolio of loans (performing and NPLs).

The description of the case study is vague and just says that it will involve cash flow modelling and analyzing the loan portfolio.

I have tried to search through the academic literature and common case study sources but did not find anything of this nature.

Any advice?
