The bondholder is then entitled to a payment of 4% of $1,000, or $40 per year, for the stated life of the bond, say, 30 years. The $40 payment typically comes in two semi-annual installments of $20 each. At the end of the 30-year life of the bond, the issuer also pays the $1,000 par value to the bondholder. INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-5 Treasury Bonds and Notes Bonds issued and guaranteed by the federal government are called Government of Canada bonds or Canadas. Maturity – Treasury notes – 1 to 10 years – Treasury bonds – 10 to 30 years Both bonds and notes may be purchased directly from the Treasury Denominations – As small as $100, but $1,000 is more common INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-6 Accrued Interest and Quoted Bond Prices The bond prices that are quoted in the financial pages are not actually the prices that investors pay for the bond. If a bond is purchased between coupon payment dates, the buyer must pay the seller for accrued interest which is the prorated share of the upcoming coupon payment. In a semi-annual coupon bond, accured interest: INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-7 Example Suppose that the coupon rate is 8%. Then the annual coupon is $80 and the semi-annual coupon payment is $40. Because 30 days have passed since the last coupon payment, the accrued interest on the bond is $40 x (30/182.5) = $6.58. Alternatively, using the annual coupon amount, we can calculate $80 x 30/365 = $6.58. If the quoted price of the bond is $990, then the invoice price or dirty price will be $990 + $6.58 = $996.58. INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-8 Accrued Interest and Quoted Bond Prices (continued) The quoted price is also called flat price. The invoice or total price paid is also called the dirty price. Example: A semi-annual coupon bond with 8% coupon rate. – Days passed since last coupon payment is 30 days – Accrued interest = $80/2 * (30/182.5) = $6.58. – If the quoted price is $990, then the invoice price will be $990+$6.58 = $993.58. INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-9 Corporate Bonds Callable bonds Some corporate bonds are issued with call provisions that allow the issuer (borrower) to repurchase the bond at a specified call price before its maturity date. For example, if a company issues a bond with a high coupon rate when market interest rates are high, and interest rates later fall, it might like to retire the high-coupon debt and issue new bonds at a lower coupon rate to reduce its interest payments. This is called refunding. A callable bond typically comes with a period of call protection, an initial time during which the bond is not callable. INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-10 Question Suppose that Telus issues two bonds with identical coupon rates and maturity dates. One bond iscallable, whereas the other is not. Which bond will sell at a higher price? The callable bond will sell at a lower price. Investors will not be willing to pay as much if they know that the firm retains a valuable option to reclaim the bond for the call price if interest rates fall. INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-11 Corporate Bonds Convertible bonds give holders option to exchange each bond for a specified number of shares of the firm’s stock Floating-rate bond has interest rate that is reset periodically according to a specified market rate INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-12 Preferred Stock Considered to be equity, but often included in the fixed-income universe – Like bonds, preferred stock promises to pay a specified cash flow stream – Unlike bonds, failure to pay the promised dividend does not result in corporate bankruptcy ▪ Dividends owed simply cumulate – Preferred stock commonly pays a fixed dividend – Rarely gives holders full voting privileges in firm INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-13 International Bonds Foreign Bonds – Issued by a borrower from a country other than the one in which the bond is sold – Denominated in the currency of the country in which it is marketed – Called Maples in Canada, Yankees in the U.S. , Samurai bonds in Japan, or Bulldog bonds in the U.K. Eurobonds – Denominated in one currency, usually that of the issuer, but sold in other national markets; e.g., Eurodollar bonds, Euroyen bonds, Eurosterling bonds, EuroCanadian bonds – Not regulated by U.S. federal agencies INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-14 Innovation in the Bond Market Inverse floaters are like floating-rate bonds, except coupon rate falls when the general level of interest rates rises Asset-backed bonds use income from a specified group of assets to service the debt Catastrophe bonds’ final payment depends on whether there has been a catastrophe Indexed bonds make payments that are tied to a general price index or the price of a commodity – Treasury Inflation Protected Securities (TIPS) Indexed Bonds – Canada Real Return Bonds (RRBs) INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-15 Principal and interest payments for an inflation-indexed bond or TIPS INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-16 Bond Pricing First term of right-hand side of equation is the present value of an annuity Second term is the present value of a single amount, the final payment of the bond’s par value Note: In general, coupons are paid semi-annually in the U.S. and Canada and annually in the Europe.

Bonds are issued at or near par value, with their prices quoted net of accrued interest. Callable bonds should offer higher promised yields to maturity Extendable and retractable bonds give the bondholder rather than the issuer the option to extend or reduce the life of the bond. Convertible bonds may be exchanged, at the bond- holder’s discretion, for a specified number of shares of stock. INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-45 Summary Floating-rate bonds pay a coupon rate with reference to a short-term interest rate. Bond prices and yields are inversely related. When bonds have default risk, the stated yield to maturity is the maximum possible yield to maturity that can be realized by the bondholder. Bond safety is often measured using financial ratio analysis. Credit default swaps provide insurance against the de- fault of a bond or loan. Collateralized debt obligations are used to reallocate the credit risk of a pool of loans. INVESTMENTS | Bodie et al. 10th CE | © 2022 McGraw-Hill Education Limited 14-46
