二价

This problem arises from the decline in bond prices and the insurance accounting convention that allows companies to carry bonds at amortized cost, regardless of market value.

事情的起因在于债券价格下跌，而会计原则又允许保险业以摊销成本而非市价列示其帐面价值，结果导致许多业者以摊销成本记录的长期债券投资金额达到其净值的二、三倍之多，换言之，只要债券价格下跌超过三分之一，便很有可能把公司的净值全部吃光，这其中甚至包括好几家知名的大公司在内，当然债券价格也有可能会回升，使得其部份，甚至全部的净值得以回复，但也没有人敢保证债券价
