We here it on the news along with print media with 'everyone' having an input (not many solutions) but just how does a company run up huge debts
I don't know much about this specific case, but nearly all large companies carry what you would probably consider large amounts of debt. Borrowing to fund growth is perfectly normal and acceptable. Being able to service that debt is obviously pretty key though.
Even Apple, famous for the amount of cash they are sitting on (over $250bn), borrow heavily and now owes over $100bn.
