Answer:
True
Explanation:
You cannot exactly determine many factors like bankruptcy costs, etc., but you can relativise certain values. For example, you can compare the current costs of taking debt vs. historic costs adjusted to market rates. If two years ago your company was able to take loans and paid market rate + 1% total interest, and now new loans cost market rate + 3.5%, it means that your debt to ratio is probably too high, at least for the market.
