Net Debt
Categories: Accounting, Credit
See: Net Borrower. It's the same thing.
If a company has cash and debt, you'd come up with their net figure, subtracting one from the other. Like...whatever.com might have this enormous $5.3 billion in debt. But if they have $5 billion in cash, then they have "only" $300 million in debt. That 300 is their net debt position.
And it's a Thing because, presumably, in a pinch, they could just use their cash to quickly pay off whatever debt was owed and be left with that smaller net amount to worry about.
