Ann: New Australian Funding Agreement, page-5

It's not a "big'un" at all.

The claim value is $100m, and cases funded by IMF typically settle for 15-20% of claim value, which is $15-20m in this case. The plaintiffs ordinarily end up with about 60% of settlement value, and the other 40% goes to IMF. So IMF might be hoping to get $6m-$8 revenue out of this deal, and given they target 2x multiple on investment, they are therefore probably hoping to spend $3-$4m to earn that $8m. Their current annual target deployment is >$100m, so this case might be 3-4% of their total annual targeted funds deployed.
