CHAPTER 8—FINANCIAL OPTIONS AND APPLICATIONS IN CORPORATE
FINANCE
TRUE/FALSE
1. An option is a contract that gives its holder the right to buy or sell an asset at a predetermined price
within a specified period of time.
2. The strike price is the price that must be paid for a share of common stock when it is bought by
exercising a warrant.
3. The exercise value is the positive difference between the current price of the stock and the strike price.
The exercise value is zero if the stock's price is below the strike price.
4. The exercise value is also called the strike price, but this term is generally used when discussing
convertibles rather than financial options.
5. As the price of a stock rises above the strike price, the value investors are willing to pay for a call
option increases because both (1) the immediate capital gain that can be realized by exercising the
option and (2) the likely exercise value of the option when it expires have both increased.
6. If the current price of a stock is below the strike price, then an option to buy the stock is worthless and
will have a zero value.
7. If the market is in equilibrium, then an option must sell at a price that is exactly equal to the difference
between the stock's current price and the option's strike price.
8. Since investors tend to dislike risk and like certainty, the more volatile a stock, the less valuable will
be an option to purchase the stock, other things held constant.
9. Because of the time value of money, the longer before an option expires, the less valuable the option
will be, other things held constant.
10. If we define the "premium" on an option to be the difference between the price at which an option sells
and the exercise value (or the difference between the stock's current market price and the strike price),
then we would expect the premium to increase as the stock price increases, other things held constant.
11. Because of the put-call parity relationship, under equilibrium conditions a put option on a stock must
sell at exactly the same price as a call option on the stock, provided the strike prices for the put and
call are the same.
12. If a company announces a change in its dividend policy from a zero target payout ratio to a 100%
payout policy, this action could be expected to increase the value of long-term options (say 5-year
options) on the firm's stock.

e.
The price of the call option will increase by $2.
21. Which of the following statements is CORRECT?
a.
Call options generally sell at a price greater than their exercise value, and the greater the
exercise value, the higher the premium on the option is likely to be.
b.
Call options generally sell at a price below their exercise value, and the greater the
exercise value, the lower the premium on the option is likely to be.
c.
Call options generally sell at a price below their exercise value, and the lower the exercise
value, the lower the premium on the option is likely to be.
d.
Because of the put-call parity relationship, under equilibrium conditions a put option on a
stock must sell at exactly the same price as a call option on the stock.
e.
If the underlying stock does not pay a dividend, it does not make good economic sense to
exercise a call option prior to its expiration date, even if this would yield an immediate
profit.
22. Which of the following statements is CORRECT?
a.
Call options generally sell at a price less than their exercise value.
b.
If a stock becomes riskier (more volatile), call options on the stock are likely to decline in
value.
c.

option, the greater the exercise value in relation to the strike price, the lower the premium
on the option is likely to be.
d.
Because of the put-call parity relationship, under equilibrium conditions a put option on a
stock must sell at exactly the same price as a call option on the stock.
e.
If the underlying stock does not pay a dividend, it makes good economic sense to exercise
a call option as soon as the stock's price exceeds the strike price by about 10%, because
this permits the option holder to lock in an immediate profit.
23. Which of the following statements is CORRECT?
a.
As the stock's price rises, the time value portion of an option on a stock increases because
the difference between the price of the stock and the fixed strike price increases.
b.
Issuing options provides companies with a low cost method of raising capital.
c.
The market value of an option depends in part on the option's time to maturity and also on
the variability of the underlying stock's price.
d.
The potential loss on an option decreases as the option sells at higher and higher prices
because the profit margin gets bigger.
e.
An option's value is determined by its exercise value, which is the market price of the
stock less its striking price. Thus, an option can't sell for more than its exercise value.

28. An analyst wants to use the Black-Scholes model to value call options on the stock of Heath
Corporation based on the following data:
•
The price of the stock is $40.
•
The strike price of the option is $40.
•
The option matures in 3 months (t = 0.25).
•
The standard deviation of the stock's returns is 0.40, and the variance is 0.16.
•
The risk-free rate is 6%.
Given this information, the analyst then calculated the following necessary components of the Black-
Scholes model:
•
d1 = 0.175
•
d2 = −0.025
•
N(d1) = 0.56946
•
N(d2) = 0.49003
N(d1) and N(d2) represent areas under a standard normal distribution function. Using the Black-
Scholes model, what is the value of the call option?
a.
$2.81
b.
$3.12
c.
$3.47
d.
$3.82
e.
$4.20
