Question：What is the potential risk for a company arising from the maturity mix of its long-term debts?

　　A. The risk arising from an imbalance between fixed and floating rate debts.

　　B. The risk that too many debts will become redeemable at the same time, putting a strain on the company's cash flows.

　　C. The risk arising from having too many long-established debts.

　　D. The risk that debts cannot be refinanced by new borrowing when they mature.

　　The correct answer is: The risk that too many debts will become redeemable at the same time, putting a strain on the company's cash flows.

　　解析：If a company has a large amount of debt maturing at about the same time, it must find the cash to make the redemption payments. To raise the cash, it must either have sufficient cash of its own, or must be able to raise new loans or issue new bonds to pay off the maturing debt.
