请问该怎么理解negotiable的含义呢，感觉这个性质没有真正的去理解

问题如下：

Which of the following is most correct regarding the Eurocommercial paper?

选项：

Eurocommerical paper is denominated in euro.

Eurocommercial paper is issued on a discount basis.

Eurocommercial paper is negotiable.

解释：

C is correct.

Commercial paper, whether US commercial paper or Eurocommercial paper, is negotiable. It may indicate that investors can buy and sell commercial paper on secondary markets.

考点：Eurocommerical paper

解析：C选项：EUCP是negotiable的，C选项正确。

A选项：EUCP的发行货币可以是任意货币，A选项不正确。

B选项：EUCP的计价方式为 interest-bearing or discount basis，但是两者相比，更常用interest-bearing，即add-on-yield。所以选项B不是最优解。
