I have a similar story: as an IBM employee I had a company Amex card. It works like this: you buy something on the card (in your name, against your personal credit), but you also fill out an expense reimbursement form (a horrible Java web-app) and IBM pays the card.
All fine and good, but if you return something or if the vendor gives you a discount later or anything like that, you end up with a negative balance on the card. Now you leave the company, but you have an Amex card with a negative balance.
I received Amex statements for six months before they figured out how to deal with it.
