Assignment On Cost of Capital Math Solution

 Cost of Capital Math solution

By (M. Shajahan Mina)

 

Exercise # 01:

Calculate the explicit costs of debt for each of the following situations, assuming (a) tax rate of 40 percent, (b) coupon rate of interest on debentures is 14 percent, (c) par value of the debenture is Tk 3000 each.

 

(A)   If debentures are sold at par and floatation costs are 2 percent;

(B)    If debentures are sold at premium of 10 percent and floatation costs are 3 percent;

(C)    If debentures are sold at discount of 5 percent and floatation costs are 3 percent.

 

Solution    Given

Tax rate (T) = 0.40

Face value of debenture (FV) = 3000

Net sale value of debenture (NSV) = 3000 – 3000 ´ 0.02 = 2940

Interest on debenture (I) = 3000 ´ 0.14 = 420

Number of year or Maturity period (N) = 1 year

 

Requirement: Cost of debt (Kd) = ?

 

(A) Debenture sold at par:

Kd = =

= 10.51% [Ans.]

 

(B) Debenture sold at 10% premium:

NSV = (3000 ´ 1.10) – (3000 ´ 1.10) ´ 0.03 = 3201

 

Kd = =

= 1.64% [Ans.]

(C) Debenture sold at 5% discount:

NSV = (3000 ´ 0.95) – (3000 ´ 0.95) ´ 0.03 = 2764.5

 

Kd = =

= 16.91% [Ans.]

Exercise # 04

XYZ Company has debentures outstanding with 5 years left before maturity. The debentures are currently selling for Tk 90 (the face value is Tk 100). The debentures are to be redeemed at 5 percent premium. The interest is paid annually at a rate of 12 percent. The firm tax rate is 40 percent. Calculate the cost of debenture.

 

Solution    Given

Tax rate (T) = 0.40

Face value of debenture (FV) = 100

Redeemed value (RV) = 100 + 100 ´ 0.05 = 105

Net sale value of debenture (NSV) = 90

Interest on debenture (I) = 100 ´ 0.12 = 12

Number of year or Maturity period (N) = 5 years

 

Requirement: Cost of debenture (Kd) = ?

 

   Kd = =

Exercise # 05

From the following information, determine the cost of equity capital using the CAPM approach.

 

(A)   Rate of return on risk-free security 10 percent.

(B)    Rate of return on market portfolio of investments is 13 percent.

(C)    The firm’s beta is 1.6, 1.25 and 1.75.

 

 

Solution                  Given   Rate of risk-free return (Rf) = 0.10

Rate of of return on market portfolio (Rm) = 0.13

Beta risk (b) = 1.6

Requirement: Cost of equity capital (Ke) = ?

 

When b = 1.6,

Ke = Rf + (Rm – Rf)b

= 0.10 + (0.13 – 0.10)1.6

= 14.80%  [Ans.]

 

When b = 1.25,

Ke = Rf + (Rm – Rf)b

= 0.10 + (0.13 – 0.10)1.25

= 13.75%  [Ans.]

 

When b = 1.75,

Ke = Rf + (Rm – Rf)b

= 0.10 + (0.13 – 0.10)1.75

= 15.25%  [Ans.]

 

 

 

Exercise # 06

Investors require a 12 percent rate of return on equity shares of company Y. What would be the market price of the shares if the previous dividend (Do) was Tk 2 and investors expect dividends to grow at a constant rate of (i) 4 percent (ii) 5 percent (iii) – 4 percent, (iv) 10 percent?

 

 

Solution         Given   Required rate of return on equity (K) = 0.12

Dividend per share (Do) = 2

(iv) When growth rate (g) = 0.10, then

P = =  = Tk 110  [Ans.]

 

 

 

 

Exercise # 07

A mining company’s iron ore reserves are being depleted, and its cost of recovering a declining quantity of iron ore are rising each year. As a result, the company’s earnings and dividends are declining, at a rate of 8 percent per year. If the previous year’s dividend (Do) was Tk 12 and the required rate of return is 15 percent, what would be the current price of the equity share of the company?

 

 

Solution                  Given,  Required rate of return (K) = 0.15

Dividend per share (Do) = 12

Growth rate (g) = – 0.08

Requirement: Current market price per share (P) = ?

 

P =

Exercise # 08

A large-sized chemical company has been expected to grow at 14 percent per year for the next 4 years and then to grow indefinitely at the same rate as the original economy, i.e., 5 percent. The required rate of return on the equity shares is 12 percent. Assume that the company paid a dividend of Tk 12 per share last year. Determine the market price of the shares today.

 

 

Solution                  Given   Required rate of return (K) = 0.12

Dividend per share (Do) = 12

Growth rate (g) = 0.05

Requirement: Current market price per share (P) = ?

 

P = =  = Tk 108  [Ans.]

 

 

 

Exercise # 09

(A) A company’s debentures of the face value Tk 1000 bear 14 percent coupon rate. Debentures of this type currently yield 15 percent. What is the market price of debentures of the company?

 

(B) What would happen to the market price of the debentures if it rises to (i) 16 percent, and (ii) drops to 12 percent.

 

(C) What would happen to the market price of the debentures in situation (A) if it is assumed that debentures were originally having a 15-year maturity period and the maturity period is 4 years away from now.

 

(D)    Would you pay Tk 900 to purchase debentures specified in situation (C)? Explain

 

 

Solution    Given

Face value of debenture (FV) = 1000

Interest on debenture (I) = 1000 ´ 0.14 = 140

Cost of debt/yield (Kd) = 0.15

 

Requirement: Current market price per share (P) = ?

 

(A)     P = =  = Tk 933.33  [Ans.]

(B)(i) When Kd = 0.16, then

P = =  = Tk 875  [Ans.]

Exercise # 12

A public limited company has the following capital structure:

Common share (40000 shares)           Tk 4000000

10% Preference share                               1000000

14% Debentures                                        3000000

Total                                                            8000000

 

The share of the company sells for Tk 200. It is expected that the company will pay next year a dividend of Tk 20 per share which will grow at 7 percent for ever. Assume a 30 percent tax rate.

 

You are required to:

(A)   Compute weighted average cost of capital based on existing capital structures.

(B)    Compute the new weighted average cost of capital if the company raises an additional Tk 2000000 debt by issuing 15 % debenture. This would result in increasing the expected dividend to Tk 30 and leave the growth rate unchanged, but the price of share will fall to Tk 150 per share.

(C)    Compute the cost of capital if in (B) above growth rate increases to 10 percent.

The new debentures can be issued at a coupon interest rate of 13 percent. The company’s debenture is currently selling at Tk 96. The new preference share issue will sell a net price of Tk 20, paying a dividend of Tk 2 per share. The company’s marginal tax rate is 30 percent.

 

(A)   Calculate the after-tax cost (i) of new debt, (ii) of new preference capital and (iii) of common equity, assuming new equity comes from retained earnings.

(B)    Find the marginal cost of capital, again assuming on new common shares are sold.

(C)    How much can be spent for capital investments before new common share must be sold? Assume the retained earnings available for next year’s investment is 50 percent of 1998 earnings.

(D)    What is the marginal cost of capital (cost of funds raised in excess of the amount calculated in part C) if the firm can sell new common share to net Tk 20 a share? The cost of debt and of preference capital is constant.

 

 

Solution

(A)(i) Kd =  = = 9.48%   [Ans.]

(A)(ii) Kp =  = = 10%   [Ans.]

(A)(iii) Ke =  = 14.72%   [Ans.]

(B) MCC = (0.15´0.0948) + (0.05´0.10) + (0.80´0.1472) = 13.698%

(C) Total expenditure = = Tk 147500

(D) Here new Ke =  = 0.159

WACC = (0.15´0.0948) + (0.05´0.10) + (0.80´0.159) = 14.642%
