问题如下:
A fixed-income portfolio analyst is applying the Merton model to derive the market value of debt for a non-dividend paying chemical manufacturing company whose assets have a current market value of CAD 85 million. The face value of the company’s only debt, a zero-coupon bond maturing in 2 years, is CAD 55 million. The analyst uses the following additional information to complete the calculation:
•N(d1): 0.9495
•N(d2): 0.8983
•Annual risk-free interest rate: 5%
•Annual volatility of the company’s assets: 26%
What is the correct estimate of the market value of the company’s debt using the Merton model?
选项:
A.CAD 48.996 million
CAD 49.764 million
CAD 53.699 million
CAD 54.056 million
解释:
A is correct. Applying the Merton model, first calculate the value of equity (S), expressed as follows:
where:
V = CAD 85 million = market value of assets
N(d1) = 0.9495
N(d2) = 0.8983
D = CAD 55 million = face value of the zero-coupon bond
e^(-RT) = e^(-0.05*2) = 0.9048
Thus,
E = (85,000,000)*(0.9495) – (0.9048)*(55,000,000)*(0.8983)
= 80,707,500 – 44,703,001
= CAD 36,004,499.
Therefore, Market value of debt = V – E = 85,000,000 – 36,004,499 = CAD 48,995,501
B is incorrect. CAD 49,764,000 is the face value of debt discounted over 2 years.
C is incorrect. CAD 53,699,000 is the result obtained if the discount factor (e-RT) in the formula for equity value is not applied.
D is incorrect. CAD 54,056,000 is the result obtained if N(d2) in the formula for equity value is not applied.
解析中这个公式是怎么来的呢,为啥这个等式成立
