That debt is short term. I think it was with USB on a 2 year note that's backed up by a deed on their building which was paid for. All they need to do to pay it off is either refi the property on a 30 year which they can then write off the interest and depreciate it to death, or work out the terms with UBS. I think for sure they'll do the first.
The point is, it's not a true liability to the company operations like most heavy infrastructure stocks like most telecoms have in which the entire company exists on debt.
