coupon bond curves are inputted when evaluating convertible bonds issued by com-

panies with di® erent credit ratings. Thus the e® ect of the company s credit on the

price of the convertible bond is easily and accurately included during the computa-

tion. In the model for the interest rate, the parameters in the variance are determined

from the market data by statistics and the market price of risk is determined by a

zero-coupon bond curve through solving an inverse problem. When we price the con-

vertible bond, a free-boundary problem is solved. A Singularity-Separating Method

(SSM) is proposed in order to solve this problem e±ciently. Taking the market data
