I read it as meaning IMF are going to take other people's or companies' money and use it to fund new cases. Then they will share the returns with those "investors" when said cases are won.
Effectively this is turning litigation funding into a new type of managed fund and yes, in answer to your question IMF would become an investment company.
There is a huge benefit to IMF by doing this as they can rapidly fund a lot more cases (and thus grow quickly into what seems to be a huge US market) by using other people's capital, instead of raising cash by CR exercises and diluting shares on issue. Also the investors can share the spoils of a new type of investing asset which seems to be a pretty profitable one.
In all it means more growth, which is a good thing!
