英文摘要：

The convertible bonds issue is studied. The value of convertible bonds depends on the stock price, the company value, the default risk, callability and puttability factors. Assuming that the stock price and the company value both follow the jump diffusion processes, this paper deduces the pricing formula of convertible bonds with default risk, callability and puttability by applying the risk neutral pricing principle and the law of total expectation.
