Same for Accounting and Tax Risk.
I have no clear answer in my head but I can try to make it up in a reasonable way here :
The financial risks that are defined as a such by CFAI imply a very explicit and current financial impact and are the main ones involved along the Investment management process (Market Risk, Liquidity Risk, Credit Risk) on the investments while the non financial risks are all the left
In the end it’s just a model to draw up a non-exhaustive list of identified risks along the Risk management process.
Sorry whether I haven’t been that clear, good question though.
