(often a multiple of $1,000)

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 4

Coupon rate:

The periodic interest payments promisedto bondholders are a fixed percentage ofa bond’s face value; this percentage isknown as the coupon rate

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 5

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 7

Call Provisions

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 8

A bond containing such aprovision is said to be callable

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 9

This call option is known asan embedded option, sinceit can’t be bought or soldseparately from the bond

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 10

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 11

A bond containing such aprovision is said to be putable

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 12

Sinking Fund Provisions

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 13

BOND ISSUERS

Bonds can be categorizedaccording to their issuers:

Treasury Bonds

Corporate Bonds

Municipal Bonds

Foreign Bonds

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 15

TREASURY BONDS

Treasury bonds are issued by the U.S.government to finance its deficits

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 16

These are free of default risk, whichis the risk that the investor will notreceive all promised payments

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 17

They are also not taxed bystate and local governments

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 18

CORPORATE BONDS

Corporations can raise funds by issuingdebt in the form of corporate bonds

These bonds offer a higher promisedcoupon rate than Treasuries, but exposeinvestors to default risk

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 19

Ratings agencies, such as Standard andPoor’s and Moody’s, rank corporate issuersaccording to their likelihood of default

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 20

The riskiest corporations offer thehighest coupon rates to investorsas compensation for default risk

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 21

MUNICIPAL BONDS

A municipal bond is issued by a state orlocal government; as a result, they carrylittle or no default risk

They also offer an extremely favorabletax treatment to investors

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 22

A municipal bond is nottaxed at the Federal level

It is also not taxed by theissuing municipality

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 23

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 24

FOREIGN BONDS

These may be denominated in dollarsor in a foreign currency

ILLUSTRATING A

BOND’S CASH FLOWS

A bond’s cash flows maybe shown with a time line

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 26

EXAMPLE

Suppose that a bond is issued with:

a face value of $1,000

a coupon rate of 4%

a maturity of four years

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 27

With a face value of $1,000, thebond will make an annual couponpayment of:

4%* $1,000 = $40

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 28

On the bond’s maturity date, the bond pays:

one final $40 coupon

the face value of $1,000

Therefore, the final cash flow totals $1,040

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 29

This is shown as follows:

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 30

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 31

where:

VB = the bond’s price or value

rd = the interest rate used to computethe present value of the bond’s cashflows; this is known as the discount

rate

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 32

NOTE

The appropriate discount rate to use forpricing a bond depends on several factors,including the bond’s default risk and maturity

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 33

PRICING BONDS

A bond’s price equals the present value

of its expected future cash flows

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 34

EXAMPLE

Referring to the previous example,suppose that the appropriatediscount rate for this bond is 4%.

What is the price of this bond?

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 35

PRICING BONDS

WITH FORMULAS

A bond may be priced with thefollowing formula:

VB =INT

(1+ rd )t+

M

(1+ rd )N

t=1

N

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 36

where:

INT = the periodic coupon or interest payment

rd = the discount rate

M = the bond’s par or face value

N = the number of periods until thebond’s maturity date

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 37

In this example, the price is computed as:

40

(1.04)1+

40

(1.04)2+

40

(1.04)3+1,040

(1.04)4

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 38

This equals:

38.4615 + 36.9822 + 35.5599+ 888.9964 = $1,000.00

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 39

At a discount rate of 5%, the price is:

40

(1.05)1+

40

(1.05)2+

40

(1.05)3+1,040

(1.05)4

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 40

This equals:

38.0952 + 36.2812 + 34.5535+ 855.6106 = $964.54

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 41

At a discount rate of 3%, the price is:

40

(1.03)1+

40

(1.03)2+

40

(1.03)3+1,040

(1.03)4

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 42

This equals:

38.8350 + 37.7038 + 36.6057+ 924.0265 = $1,037.17

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 43

These results show the followingimportant relationship:

If rd > coupon rate, VB < face value

If rd = coupon rate, VB = face value

If rd < coupon rate, VB > face value

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 44

These results also demonstrate that thereis an inverse relationship between interestrates and bond prices:

when rates rise, bond prices fall

when rates fall, bond prices rise

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 45

NOTE

A bond that sells for less than its facevalue is known as a discount bond

A bond that sells for more than its facevalue is known as a premium bond

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 46

ZERO COUPON BONDS

A zero-coupon bond does not make anycoupon payments; instead, it is sold toinvestors at a discount from face value

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 47

The difference between theprice paid for the bond and theface value represents the returnto the investor

This is known as a capital gain

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 48

The pricing formula fora zero coupon bond is:

VB =M

(1+ rd )N

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 49

EXAMPLE

A one-year zero-coupon bondis issued with a face value of$1,000. The discount rate forthis bond is 8%. What is themarket price of this bond?

(c) ECI RISK TRAINING 2009www.ecirisktraining.com 50

VB =M

(1+ rd )N=

1,000

(1+ .08)1= $925.93
