Lesson Eleven / Twelve
Bonds – The Basics
Bonds are simply a promise to repay an amount borrowed with interest. Bonds are issued by
governments, as well as corporations, and sometimes by municipalities. Each bond issue has its
own maturity date, coupon rate and features. A bond issue refers to all of the individual bonds
issued using a specific bond indenture, meaning that the bond indenture may authorize $100
million of bonds to be issued in total, with individual bonds, each being part of the bond issue,
sold in denominations of $50,000 or $100,000. The term debenture refers to an unsecured
bond, meaning that the issuer has not provided any security or collateral to protect the
purchaser in the case of default (bankruptcy) of the issuer. Remember, the issuer is the
company or government [the borrower] and the buyer is the investor [the lender].
Corporations can issue bonds and debentures, and normally, a debenture will pay a higher rate
of interest (also called the coupon rate) since a debenture is not secured; and therefore, is a
riskier investment. Corporate bonds can be secured by physical assets, such as property,
buildings, equipment and train cars, or by financial assets, such as stocks, bonds or other
securities. Government bonds are different, in that they are not secured by physical assets; they
are secured by the government’s power of taxation, meaning that the government in power can
simply raise taxes to pay interest or principal payments to its bondholders.
Bonds generally have a fixed interest rate, which is paid by the borrower (company or
government) to the lender (investor). The payment of interest compensates the lender for the
missed opportunity cost of not having their principal, as well as the risk of not having their
principal repaid. For example, a 6% bond (i.e. a 6% coupon rate) with a $1,000 face value will
pay $30 of interest every six months. Most bonds in Canada make semi-annual interest
payments. Don’t confuse “yield” with “coupon rate”. The coupon rate paid on a bond does not
change over time, whereas the bond’s yield will change daily, and even throughout the day. The
coupon rate is set by the issuer when the bond is first issued and reflects one thing, the interest
payments made by the issuer. The yield of a bond includes two things, the interest payments
made by the issuer, and the gain or loss on the face value of the bond.
Consider this example: Campwealth Inc. issues a 4%, two year debenture today. Assume that
the coupon rate of 4% reflects the current interest rate required for similar bonds, meaning
bonds with similar risk and a similar maturity date, etc. The price of the bonds will be $1,000 for
each $1,000 of face value, which means that the bonds are trading at “par”, so the yield is 4%
(4% coupon + 0% gain/loss on face value for bonds trading at par).
Over the next year, if Campwealth runs into financial difficulty and become a more risky
investment, investors will want to earn more than 4% on a bond investment; so the price of
Campwealth bonds will drop. Let’s assume the price drops to $909 for every $1,000 of face
value. Recall that yield is calculated by adding your coupon rate + the gain/loss on face value, so
the yield is now calculated by adding the 4% coupon + 10% gain = 14%. The gain on face value is
calculated as [($1,000 – $909) / $909 ] = 10%.
