Reading 56: Valuing Bonds with Embedded Options

LOS j: Describe and evaluate a convertible bond and its various component values.

 

 

For a convertible bond, which of the following is least accurate?

A) The conversion ratio times the price per share of common stock is a lower limit on the bond's price.

B) A convertible bond may be putable.

C) The issuer can decide when to convert the bonds to stock.

---

 

All of these are true except the possibility of the issuer to force conversion. The bondholder has the option to convert.

Which of the following is equal to the value of a noncallable / nonputable convertible bond? The value of the corresponding:

A) callable bond plus the value of the call option on the stock.

B) straight bond.

C) straight bond plus the value of the call option on the stock.

---

The value of a noncallable/nonputable convertible bond can be expressed as:

Option-free convertible bond value = straight value + value of the call option on the stock.

土豆妮

For a convertible bond without any other options, the call feature implied by the convertibility feature will do all of the following EXCEPT:

A) increase the value of the bond over that of a comparable option-free bond.

B) place a lower limit on the possible values of the bond.

C) cause negative convexity.

---

Negative convexity is caused by the bond being callable where the issuer has the embedded call option. Negative convexity does not apply to convertible bonds. The convertibility feature gives the bondholder a call option on the shares of common stock of the issuer. This increases the price of the bond and places a lower limit on the possible values of the bond. However, that lower limit will change with the price of the common stock.

Which of the following factors must be included in an option-based valuation approach to price a callable convertible bond?

A) Interest rates, stock prices and their correlation.

B) Stock prices only.

C) Interest rates and stock prices only.

---

The valuation of convertible bonds with embedded call and/or put options requires a model that links the movement of interest rates and stock prices.

A convertible bond has a conversion ratio of 12 and a straight value of $1,010. The market value of the bond is $1,055, and the market value of the stock is $75. What is the market conversion price and premium over straight value of the bond?

Market conversion price

Premium over straight value

A) $75.00 0.1029

B) $84.17 0.1222

C) $87.92 0.0446

---

The market conversion price is:

(market price of the bond) / (conversion ratio) = $1,055 / 12 = $87.92.

The premium over straight price is:

(market price of bond) / (straight value) ? 1 = ($1,055 / $1,010) ? 1 = 0.0446.

For a convertible bond with a call provision, with respect to the bond's convertibility feature and the call feature, the Black-Scholes option model can apply to:

A) both features.

B) neither features.

C) only one feature.

---

The Black-Scholes model applies to the convertibility feature just as it does to the common stock. The Black-Scholes model is not appropriate for the call feature because the volatility of the bond cannot be assumed constant.

土豆妮

What is the market conversion price of a convertible security?

A) The value of the security if it is converted immediately.

B) The price that an investor pays for the common stock in the market.

C) The price that an investor pays for the common stock if the convertible bond is purchased and then converted into the stock.

---

The market conversion price, or conversion parity price, is the price that the convertible bondholder would effectively pay for the stock if she bought the bond and immediately converted it.

market conversion price = market price of convertible bond ÷ conversion ratio.

土豆妮

Suppose the market price of a convertible security is $1,050 and the conversion ratio is 26.64. What is the market conversion price?

A) $1,050.00.

B) $26.64.

C) $39.41.

---

The market conversion price is computed as follows:

Market conversion price = market price of convertible security/conversion ratio = $1,050/26.64 = $39.41

土豆妮

Which of the following statements is most accurate concerning a convertible bond? A convertible bond's value depends:

A) only on interest rate changes.

B) on both interest rate changes and changes in the market price of the stock.

C) only on changes in the market price of the stock.

---

The value of convertible bond includes the value of a straight bond plus an option giving the bondholder the right to buy the common stock of the issuer. Hence, interest rates affect the bond value and the underlying stock price affects the option value.

土豆妮

Which of the following correctly describes one of the basic features of a convertible bond? A convertible bond is a security that can be converted into:

A) common stock at the option of the issuer.

B) another bond at the option of the issuer.

C) common stock at the option of the investor.

---

The owner of a convertible bond can exchange the bond for the common shares of the issuer.
