Bond Valuation and Interest Rates The Basic Structure of Bonds Bond Valuation Bond Yields Current Yield, Capital Gain (loss) Yield, &Total Yield Yield to Maturity, Yield to Call, Holding Period Yield Realized Rate of Return Relationship between interest rate and bond price Interest Rate Determinants Bond Ratings Other Types of Bonds/Debt Instruments 1 The Basic Structure of Bonds • In the broadest sense, a bond is any debt instrument that promises a fixed income stream to the holder • Bonds usually have the following characteristics: • A fixed face or par value, paid to the holder at maturity • A fixed coupon, which specifies the interest payable over the life of the bond • A fixed maturity date • Fixed income securities are often classified according to maturity: • Bills or paper have maturities less than one year • Notes have maturities between one and seven years • Bonds have maturities greater than seven years • Bonds may be either bearer bonds or registered bonds 2 The Basic Structure of Bonds • The market price of a bond is the present value of the payments promised by the bond 0 1 2 3 t |---------------|------------------|------------------|---|---|---|----| C C C C C C C +F • The bond indenture is the contract between issuer and holder, which specifies: • • • • • Details regarding payment terms Collateral Positive or negative covenants Par value or face value (usually in increments of $1,000) Bond pricing, usually shown as the price per $100 of par value which is equal to a percentage of the bond’s face value 3 The Basic Structure of Bonds • Term to maturity is the time remaining to the maturity date • Coupon rate is the annual percentage interest paid on the bond’s face value • Multiply the coupon rate by the bond’s face value to calculate coupon, and divide by two if the coupon is paid semi-annually • Example: A $1,000 bond with an 8% coupon rate will have an $80 annual coupon or a $40 semi-annual coupon • Security and protective provisions: • Mortgage bonds are secured by real assets • Debentures are either unsecured or secured, with a floating charge over the firm’s assets • Collateral trust bonds are secured by pledged financial assets, such as common stock, other bonds or Treasury bills • Equipment trust certificates are secured by pledged equipment, such as railway rolling stock 4 The Basic Structure of Bonds • Covenants are another type of protective provision • Positive covenants specify actions the firm agrees to do, such as supply periodic financial statements and maintain certain ratios • Negative covenants specify actions the firm agrees to avoid, such as restrictions on the size of its debt or acquiring or disposing of assets • Call features allow the issuer to redeem or pay off the bond prior to maturity, usually at a premium • Retractable bonds allow the holder to extend bonds back to the issuer before maturity • Extendible bonds allow the holder to extend the bond’s maturity • Sinking funds are funds set aside by the issuer to ensure the firm is able to redeem the bond at maturity • Convertible bonds can be converted into common stock at a predetermined conversion price 5 Bond Market Reporting CANADA Canada Coupon 6.375 Mat. Date Dec 31/20 The Government of Canada issued this bond The bond pays an annual coupon rate of 6.375% The bond matures on December 31, 2020 Bid $ 107.05 Yld% 5.00 The bond’s quoted annual yield to maturity is 5% The bond is selling at 107.05% of the face value of $1,000 Level Coupon Bonds • Make periodic coupon payments in addition to the maturity value • The payments are equal each period. Therefore, the bond is just a combination of an annuity and a terminal (maturity) value. • Coupon payments are typically semiannual. 7 Level-Coupon Bonds Information needed to value level-coupon bonds: – Coupon payment dates and time to maturity (t) – Coupon payment (C) per period and Face value (F) – Discount rate 0 1 2 3 t |-------------------------|-------------------------|-------------------------|---|---|---|---|-------| C C C C C C C C+F Value of a Level-coupon bond = PV of coupon payment annuity + PV of face value πΆπΆ 1 πΉπΉ ππππ = 1 − + = πΆπΆ ππ (1 + ππ)π‘π‘ (1 + ππ)π‘π‘ 1− 1 1 + ππ ππ π‘π‘ πΉπΉ + 1 + ππ π‘π‘ 8 LEVEL COUPON BOND QUESTION 1 On January 1, 2014 CC Rated Inc.

Bond prices and market interest rates move in opposite directions. 2. When coupon rate = YTM, price = par value. When coupon rate > YTM, price > par value (premium bond) When coupon rate < YTM, price < par value (discount bond) 19 Bond Concepts 3. A bond with longer maturity has higher relative (%) price change than one with shorter maturity when interest rate (YTM) changes. All other features are identical.

Determine the price if the required rate of return is 6%. PV= C/r = $30/0.06 = $500 44 Other Types of Bonds and Debt Instruments Floating Rate, Real Return, and CSBs Floating rate bonds have coupon rates that float with some reference rate, such as the yield on Treasury bills • Since the coupon rate floats, or is variable, the market price will typically be close to the bond’s face value Real return bonds are issued by the Government of Canada to protect investors against unexpected inflation • Each period, the face value of the real return bond is grossed up by the inflation rate. The coupon is then paid on the grossed up face value. Canada Savings Bonds (CSBs) are issued by the Government of Canada as either regular interest bonds (interest paid annually) or compound interest bonds (interest compounds over the life of the bond) • There is no secondary market for Canada Savings Bonds; instead, they are redeemable at any chartered bank in Canada at their face value 45
