From the pdf; relating to a seperate lawsuit:
"The UMB Complaint accused Revlon of improperly amending the 2016 Loan Agreement to avoid paying the Lenders, and alleged that Revlon had defaulted on the loan. More significantly for present purposes, it alleged that Revlon was unable to repay the loan because it was “insolvent and facing a severe liquidity crisis.”
"The non-returning lenders believed, and were justified in believing, that the payments were intentional," Judge Jesse Furman ruled."
"Indeed, to believe otherwise — to believe that Citibank, one of the most sophisticated financial institutions in the world, had made a mistake that had never happened before, to the tune of nearly $1bn — would have been borderline irrational."
I think the lenders would've known it was a mistake on the basis that the debtor wasn't liquid enough to repay the load. Don't think the judge's reasoning here holds up. I'm sure the lenders were sophisticated enough to realise bad loans don't get repaid in full, ahead of time, intentionally.
