INTRODUCTION
 Debt markets are used by both firms and
governments to raise funds for long-term
purposes, though most investment by firms is
financed by retained profits. Bonds are long-
term borrowing instruments for the issuer.
Major issuers of bonds are governments
(Treasury bonds in US, gilts in the UK, Bunds in
Germany) and firms, which issue corporate
bonds.

BOND VALUATION

BONDS
 Bonds/ debentures are fixed income securities
containing acknowledgement of indebtedness
by the issuing company and are similar in
nature except for the issuing company.
 The bond/ debentures will contain a promise to
pay interest for a specified period and then to
repay the principal at the end of specified
period, on a given date of maturity.

TYPES OF BONDS
• Callable and putable bonds
• Convertible bonds
• Eurobonds
• Floating rate notes (FRNs)
• Foreign bonds
• Index-linked bonds.
• Junk bonds
• Covered bonds

RETURN FROM BONDS
Bonds returns are expressed in the following five
forms:
 Coupon rate
 Current yield
 Spot interest rate
 Yield to maturity or redemption yield:
 Yield to call

COUPON RATE
 It is the rate of interest fixed for a bond and
printed on the bond certificate. Interest payable
is calculated at the coupon rate on the face
value of the bond. If the face value of the bond
is, say Shs. 1000 and if the coupon rate is fixed
at, say 9% p.a. the annual interest payable by
the company to the bond holder is Shs. 90 per
bond.

CURRENT YIELD
• It is the rate of return available from a bond on its
current price in the secondary market.
• It fluctuates depending on the bond price.
• It only measures the annual rate of return accruing
to an investor who purchase the bond from the
secondary market.
Illustration
• A bond has a face value of KShs. 1,000 and a
coupon rate of 9 per annum. The bond is currently
selling in the secondary market at a price of KShs.
800. Calculate the current yield.

SPOT INTEREST RATE (SIR)
 It is the annual rate of return on a bond that offers
only one cash inflow to the investor. A zero coupon
bond offers only one cash inflow to the investor on
its maturity and hence the rate of return offered by
a zero coupon bond calculated on an annualized
basis is as “SIR”.
 Mathematically, SIR of a zero coupon bond is the
discount rate that equates the present value of the
single cash inflow available to the investor on
maturity of the bond to the price of the bond.

SIR – CONT’D: ILLUSTRATION
• A zero coupon bond of face value KShs. 1,000 is
issued at discounted price KShs. 600. The bond
has a maturity period of 5 years. Find the Spot
Interest Rate of the bond.
Solution:
• Let be the spot interest rate
• The face value of KShs. 1,000 will be received
after a period of 5 years
• Amount receivable after five years hence = KShs.

YIELD TO MATURITY
 It is the internal rate of return earned from a
bond, holding the bond till its maturity.
 It is calculated by equating bond the cost of
bond to the present value of cash inflows from
the bond held till maturity. Hence, the YTM is
the discount rate makes the cost of bond equal
to the present value of cash inflows from the
bond held till maturity.

YIELD TO CALL
 YTC is the discount rate that makes the present
values of cash inflows to call (i.e. the annual
interests till the call date and the specified call
price of the bond at which it is redeemed)
equal to the cost of the bond.
 YTC can be calculated on a similar lines as a
YTM as calculated

BOND DURATION
• It is defined as the time period at which the
price risk and the investment risk of the
bond are equal in magnitude but opposite in
direction (Nagarajan and Jayabal, 2011) .
Illustration
• A 5 years bond with a face value of KShs.
100 has a coupon rate of 10%. What is the
terminal value that will be available to the
investor in this bond, if the market interest
rate is 12%?

EQUITY MARKET

EQUITY MARKET
• Equity markets are markets which organize trading
nationally and internationally in such instruments,
as common equity, preferred shares, as well as
derivatives on equity instruments.
• The purpose of equity is the following:
a. A new issue of equity shares is an important
source of external corporate financing;
b. Equity shares perform a financing role from
internally generated funds (retained earnings);
c. Equity shares perform an institutional role as a
means of ownership.

Equity Instruments
a. Common or ordinary share (stock) is an equity share
that does not have a fixed dividend yield. It represent
partial ownership of the company and provide their
holders claims to future streams of income, paid out of
company profits and commonly referred to as
dividends.
b. Preferred share is an equity security, which carries a
predetermined constant dividend payment. It is a
financial instrument, which represents an equity
interest in a firm and which usually does not allow for
voting rights of its owners.

EQUITY INSTRUMENTS – CONT’D
The decision to issue equity against debt is based on several factors:
• Tax incentives. In many countries interest payments are tax deductible,
however dividends are taxed. Thus the tax shield of debt forms incentives to
finance company by debt.
• Cost of distress. Increase of company leverage, increases the risk of
financial insolvency and may cause distress as well as lead to bankruptcy.
Thus companies tend to minimize their credit risk and increase the portion
of equity in the capital structure.
• Agency conflicts. When a company is financed by debt, an inherent conflict
arises between debt holders and equity holders. Shareholders have
incentives to undertake a riskier operating and investment decisions,
hoping for higher profits in case of optimistic outcomes. Their incentives are
mainly based by limited liability of their investments. In case of worst
outcome debt holders may suffer more, in spite of their priority claims
towards company assets.
• Signaling effect. The companies, which issue equity to finance operations,
provide signals to the market, that current share selling price is high and
company is overvalued.

EQUITY INSTRUMENTS – CONT’D
Types of Preferred shares
• Cumulative preference shares
• Non-cumulative preferred shares
• A redeemable preferred share
• Convertible preferred shares
• Participating preferred shares
• Stepped preferred shares
• Specific adjustable rate preferred shares
• Auction rate preferred shares (ARPS) or Single point
adjustable rate shares (ARPS)
• Preferred equity redemption cumulative stocks
(PERCS)

SHARE VALUATION

SHARE VALUATION MODELS
 Share valuation means arriving at the intrinsic
value of shares. A share possess intrinsic value
because it offers returns to the shareholder in
the form of dividends and capital appreciation.

DISCOUNT RATE
 The discount rate is the rate of return required
by the investor on his investment in the share.
This rate of return is arrived at by taking into
account the risk involved in the investment. The
discount rate consist of two components: risk
free interest rate and risk premium for the
share concerned

DIVIDEND DISCOUNT MODELS
• Based on the holding period and the dividend
expected to be received, share valuation
models can be grouped into two:
a. Holding period model
• One year holding period model
• Multiple year holding period model
b. Dividend growth models
• Constant growth model
• Multiple growth model

ONE YEAR HOLDING PERIOD MODEL
Assumptions
 The investor purchases the share now
 The investor intends to hold the share for a period of one
year
 The investor intends to dispose off the share at the end of
one year

company from the secondary market. The investor
prefers to hold share for one year and dispose off the
share after on year. The investor expects to get a
dividend of KShs.5.00 per share next year and he is
hopeful of selling the share in the secondary market
at a price of KShs.70 after one year. He expects a
return of 20% on his investment, considering the level
of risk associated with it. Calculate the present value
of the share to the investor.

LIMITATIONS OF GORDON DIVIDEND
MODEL
 The use of this model is restricted to firms that have
been growing and are expected to grow at a stable
growth rate forever and are expected to offer
dividends at the stable growth rate forever.
 If the dividend growth rate in more than the required
rate of return, the model cannot be used since the
value of the stock will become negative
 If the dividend growth rate is equal to the required rate
of return, the model cannot be used since the value of
the stock will become infinity.

• M/s. Good tread company ltd, has declared a dividend
of KShs. 4.50 per equity share for the current year. As
a policy, the company has been enhancing its dividend
by 12% every year. The company is expected to follow
its dividend policy in the future also. An investor is
interested to invest in the equity shares of the
company as a long term investment. The investor
expects a return of 18% on his investment considering
