如果免去票面金额一半的债务依然资不抵债，那该怎么办呢？

If losing half the face value of a bond does not amount to a default, what does?

面值的，非市场价值的属于、关于或是一笔钱或者股票证券的票面价值量的，而并非购买力市场价值。

Of relating to or being the amount or face value of a sum of money or a stock certificate for example and not the purchasing power or market value.
