# Black-Scholes, Warrants, Leasing

1) Black-Scholes: What are the prices of a call option and a put option with the following characteristics?

Stock price = $38

Exercise price = $35

Risk -free rate = $6% per yr compounded continuously

Maturity = 3 months

Standard deviation = 54% per year

2) Warrant Value: A warrant gives its owner the right to purchase three shares of common stock at an exercise price of $32 per share. The current market price of the stock is $39. What is the minimum value of the warrant?

3) Use the following information to work problems 1-3. You work for a nuclear research lab. That is contemplating leasing a diagnostic scanner (leasing is a common practice with expensive high-tech equipment). The scanner costs $3,000,000, and it would be depreciated straight-line to zero over four years. Because of radiation contamination, it will actually be completely valueless in four years. You can lease it for $895,000 per year for four years.

1: Assume that the tax rate is 35% you can borrow at 8% before taxes should you lease or buy

2: Leasing cash flows: What are the cash flows from the lease from the lessor's viewpoint? Assume a 35 percent tax bracket.

3: Taxes and Leasing cash flows: Assume that your company does not contemplate paying taxes for the next several years. What are the cash flows from leasing in this case?

4) Setting the lease price: Raymond Rayon corp. wants to expand its manufacturing facilities. Liberty leasing corp. has offered Raymond Rayon the opportunity to lease a machine for $1,500,000 for six years. The machine will be fully depreciated by the straight -line method. The corporate tax rate for Raymond Rayon is 25 percent, whereas Liberty leasing has a corporate tax rate of 40 percent. Both companies can borrow at 8 percent. Assume lease payments occur at year -end. What IS Raymond's reservation price? What is Liberty's reservation price?

1) Black -Scholes : What are the prices of a call option and a put option with the following characteristics

Stock price = $38

Exercise price = $35

Risk -free rate = $6% per yr compounded continuously

Maturity = 3 months

Standard deviation = 54% per year

We will use Black Scholes Pricing Formula

Value of call= S N(d1) - X * e -r(T-t) * N(d2)

Value of put = X * e -r(T-t) * N(-d2) -S N(-d1)

We therefore need to calculate the values of d1 and d2

d1= {ln (S/X) + ( r + ½ s2 ) x (T-t)}/ (s x square root of (T-t))

d2= {ln (S/X) + ( r - ½ s2 ) x (T-t)}/ (s x square root of (T-t)) =d1-s x square root of (T-t)

Inputs

Stock Price= S= $38.00

Exercise price = X= $35.00

Time to expiration = T-t= 3 months = 0.25 year

Risk free rate = r = 6.00%

standard deviation = volatility= s = 54.00%

Calculations

ln S/X= 0.0822 = ln (38/35)

( r + ½ s2 ) (T-t)= 0.0515 =(0.06+0.54^2/2) x 0.25

s x square root of (T-t)= 0.2700 =0.54 x square root of 0.25

Substituting the values

d1= 0.4952 =(0.0822+0.0515) / 0.27

d2= 0.2252 =0.4952-0.27

N is the cumulative normal distribution function

N(d1) 0.6898

N(-d1)=1-N(d1)= 0.3102

N(d2) 0.5891

N(-d2)=1-N(d2)= 0.4109

X * e -r(T-t) = 34.4789 =35x e ^ (-0.06x0.25)

Thus,

Value of call= S N(d1) - X * e -r(T-t) * N(d2)= $5.9009 =38 x 0.6898 - 34.4789 x 0.5891

Value of put = X * e -r(T-t) * N(-d2) -S N(-d1) = $2.3798 =34.4789 x 0.4109 - 38 x 0.3102

We can also calculate the value of Put option using put call parity

Put call parity

c+ Xe^-(rt) = p+S

or p=c + Xe^-(rt)-Se^-(q(T-t))= $2.3798 =5.9009+34.4789-38

which is the same as obtained above

Answer:

Value of call option= $5.9009

Value of put option= $2.3798

2) Warrant Value: A warrant gives its owner the right to purchase three shares of common stock at an exercise price of $32 per share. The current market price of the stock is $39. What is the minimum value of the warrant?

Witheach warrant 3 shares can be purchased for 3 x $32= $96.00

and sold for 3 x $39 in the market= $117.00

Therefore, minimum value = $117-$96= $21.00

This is the minimum value (intrinsic value) as the warrant also has time value before expiration

Answer: $21.00

3)Using the following information to work problems 1-3. You work for a nuclear research lab. That is contemplating leasing a diagnostic scanner (leasing is a common practice with expensive high-tech equipment). The scanner costs $3,000,000, and it would be depreciated straight -line to zero over four years. Because of radiation contamination, it will actually be completely valueless in four years. You can lease it for $895,000 per year for four years.

1 :Assume that the tax rate is 35 % you can borrow at 8% before taxes should you lease or buy

Tax rate= 35%

Cost of borrowing= 8%

After tax cost of borrowing = cost of borrowing x (1-Tax rate)= 5.20% =8.% x (1- 0.35)

This is the ...
