Citigroup is the only party responsible for paying the bill. They do not themselves owe the money, but any legitimate payment would come from them. So, as the lender, what's the difference?
Revlon had not released the funds for Citigroup to pay the amount due and don't have the funds to repay the loan. Revlon's creditors had sued them the day before. Citigroup were just an intermediary and shouldn't have transferred any funds. I don't think a loan is involved in this.
