MF Global Claims Trading

I’ve been trying to understand the recent Barclays offer to buy for 91 cents on the dollar claims on the remaining 28% of missing US customer money. This seems like a very rich offer for, unlike a usual claim in bankruptcy, an asset that needs to be first located and then litigated. You basically need to get this done in a 2 year window at 100 cents to really make anything. What am I missing here? Are they not worried about a showdown with the creditors over control of any located assets?
