Page 17: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Copyright ©1998 Ian H. Giddy Equity instruments 17

The Value of a Right

The value of a right equals the difference in the price of the issuer’s outstanding shares before and after the rights offering, and is determined by three factors:

- the total amount of money to be raised,

- the subscription price of the new shares, and

- the number of existing shares.

The number of new shares to be issued equals

(Funds to be raised)/Subscription price

Page 18: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Copyright ©1998 Ian H. Giddy Equity instruments 18

The Value of a Right (concluded)

The number of rights needed to buy one share equals

(Number of old shares)/(Number of new shares)

After the offering, the new value of the firm is

Pre-offering firm value + funds raised,

and the new share price must be

(New firm value)/(Total number of shares outstanding).

The value of the right must equal

Old share price - new share price.

Page 19: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Rights Offering: Example

Rio Algom Mining Co. is proposing a rights offering. Presently there are 250,000 shares outstanding at $50 each. There will be 50,000 new shares offered at $40 each.

a. What is the new market value of the company?

b. How many rights are associated with one new share?

c. What is the ex-rights price?

d. What is the value of a right?

e. Why might a company have a rights offering rather than a general cash offer?

Page 20: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Copyright ©1998 Ian H. Giddy Equity instruments 20

Rights Offering: Example (cont.)

a. New value = (250,000 $50) + (50,000 $40)$14.5 million

b. There will be (250,000/ _______ ) = ____ rights associated with each new share.

c. The ex-rights price is $14.5 million/300,000 = $48.33.

d. The value of one right equals $____48.33 = $1.67.

What is the Effect of an Equity Offering on Shareholder Value?

Dilution - loss in existing shareholders’ value

Dilution of proportionate ownership Dilution of market value Dilution of book value and earnings

per share (EPS) Under what circumstances does

market value dilution occur?

Equity-Linked Bonds

Bonds with warrants Convertible Bonds Index-linked Bonds

These are all example of hybrid bonds and should be priced by decomposition

Page 25: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Copyright ©1998 Ian H. Giddy Equity instruments 25

Stock-Purchase Warrants

Warrants are usually detachable and trade on the securities exchanges

Warrants are often added to a large debt issue as “sweeteners” to enhance the marketability of the issue

Exercise price Warrants usually have a limited life of about 10

years or less Warrants differ from rights and convertibles

Page 26: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Copyright ©1998 Ian H. Giddy Equity instruments 26

The Implied Price of an Attached Warrant

To determine the implied price of an attached warrant, the implied price of all warrants attached to a bond must be determined

Implied price of all warrants = price of bond with warrants attached - the straight bond value (of similar-risk bonds)

The implied price of a single warrant is the implied price of all warrants divided by the number of warrants attached to each bond

Page 27: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Copyright ©1998 Ian H. Giddy Equity instruments 27

The Value of Warrants

A warrant has a “theoretical value” at any point in time prior to its expiration date

The theoretical value can be calculated as:

TVW = (Po - E) x NWHERE:

TVW = Theoretical value of a warrant

Po = Current market price of one share of common stock

E = Exercise price of the warrant

N = Number of shares of common stock

obtainable with one warrant

Page 28: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Copyright ©1998 Ian H. Giddy Equity instruments 28

Sony Warrants

Sony Electronics has outstanding warrants exercisable at Yen400/share that entitle holders to purchase three shares of common stock per warrant. If Sony’s common stock is currently selling for Y45/share, the TVW =

TVW = (Y45 - Y40) x 3 = Y15The market value of a warrant is generally greater than

its theoretical value; the difference, known as the warrant premium is due to investor expectations and opportunities for further gain before expiration.

Convertible Bonds

Bond may be converted into stock The Conversion Ratio is the number of

shares of common stock that can be received in exchange for each convertible security

The Conversion Price is the per share common stock price at which the exchange effectively takes place

Page 31: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Copyright ©1998 Ian H. Giddy Equity instruments 31

Convertibles

The Conversion Period is a limited time within which a security may be exchanged for common stock

The Conversion Value is the market value of the security based upon the conversion ratio times the current market price of the firm's common stock

Earnings effects: Firms must report Primary EPS, treating all contingent

securities that derive their value from their conversion privileges or common stock characteristics as common stock

Firms must report Fully Diluted EPS treating all contingent securities as common stock

Page 32: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Copyright ©1998 Ian H. Giddy Equity instruments 32

Example: Hyundai Euroconvertible

If Hyundai issues a Eurobond with a $1,000 par value that is convertible at $40 per share of common stock, the conversion ratio =

$1,000 = 25

$40 If Hyundai had stated the conversion ratio at 20, the

conversion price =

$1,000 = $50

Copyright ©1998 Ian H. Giddy Equity instruments 33

Financing With Convertibles

Motives for using convertibles include: It is a deferred sale of common stock that decreases the

dilution of both ownership and earnings They can be used as a “sweetener” for financing They can be sold at a lower interest rate than nonconvertibles They have far fewer restrictive covenants than

nonconvertibles It provides a temporarily cheap source of funds (assuming

bonds) for financing projects Most convertibles have a call feature that enables the issuer to

force conversion when the price of the common stock rises above the conversion price

Page 34: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Copyright ©1998 Ian H. Giddy Equity instruments 34

Determining the Value of a Convertible Bond

There are three values associated with a convertible bond:Straight Bond Value is the price at which the bond

would sell in the market without the conversion featureThe Conversion Value is the product of the current

market price of stock times the conversion ratio of the bond

The Market Value is the straight or conversion value plus a market premium based upon future (expected) stock price movements that will enhance the value of the conversion feature

Page 35: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Siam Cement

Siam Cement sold a $1,000 par value, 20-year convertible bond with a 12% coupon. A straight bond would have been sold with a 14% coupon. The conversion ratio is 20

Straight Bond Value$120 x (PVIFA14%,20) + $1,000 x (PVIF14%,20) =$120 x (6.623) + $1,000 x (.073) = $867.76

Conversion Value at various market prices of stock

70 1,400 80 1,600

The straight bond value is the minimum price at which the convertible bond would be traded

Equity Risk and Return: Summary

Investors diversify, because you get a better return for a given risk.

There is a fully-diversified “market portfolio” that we should all choose

The risk of an individual asset can be measured by how much risk it adds to the “market portfolio.”

Portfolio Return...

To compute the return of a portfolio: use the weighted average of the returns of all assets in the portfolio, with the weight given each asset calculated as

(value of asset)/(value of portfolio).

The portfolio return E(Rp) is:

E(Rp) = (w1k1)+(w2k2)+ ... (wnkn) = wj kj

where wj = weight of asset j, kj = return on asset j

Page 46: Equity Instruments And Portfolio Construction Prof. Ian Giddy New York University New York University/ING Barings.

Copyright ©1998 Ian H. Giddy Equity instruments 46

...and Risk (Standard Deviation)

Portfolio return is the weighted average of all assets’ returns,

But portfolio standard deviation is normally less than the weighted average of all assets’ standard deviations!

The reason: asset returns are imperfectly correlated.

The Equation for the CAPM

Rj = RF + j (Rm - RF)where:Rj = Required return on asset j;

RF = Risk-free rate of return

j = Beta Coefficient for asset j;

Rm = Market return

The term [j(Rm - RF)] is called the risk premium and (Rm-RF) is called the market risk premium
