  1. Chapter 10 Valuation and Rates of Return

  2. Growing Characteristic of Money • In 1624, the Indians sold Manhattan Island for $24. • If the Indians had invested the $24 at 7.5% compounded annually, they would now have over $15 trillion - sufficient to repurchase most of the New York City. • Due to the growing property of money (i.e., interest may be earned on the current money) a dollar today is worth more than a dollar tomorrow

  3. Winner of $10 million • The $10 million is paid out as $500K the first year, $250K for the next 29 years and a final payment of $2.25 million. • Assuming a discount rate of 10%, the present value of the rewards is less than $3 million • the longer you have to wait to receive the dollar, the less it is worth

  4. Time Value of Money • The value of $1 in different points in the future are not the same • In order to make comparison, we have to convert the money back to the same point in time • Normally we will use the present as the reference point in time

  5. Valuation of Securities • Most of the securities will promise the holders a certain form of cash flow in the future • E.g. a corporate bond guarantees a yearly payment of interest ($100) and a preferred stock provides an biannual interest payment of $200, which one will worth more?

  6. Valuation of Securities cont’ • To answer this question, we need to know the present value of the interest payments. • That is, the equivalent amount of current money for the future income.

  7. PV Formula • FV = PV (1+i )^n • PV = FV/(1+i )^n • In table form, • FV = PV x FVIF • PV = FV x PVIF

  8. Present Value Calculation • Assume an compound interest rate of 10% p.a. • Corporate Bond: • PV of $100 in 1 yr = $90.91= $100/(1+10%) • PV of $100 in 2 yrs = $82.64= $100/(1+10%)^2 • Total = $90.91+ $82.64 = $173.55 • Preferred Stock: • PV of $200 in 2 yrs= $200/(1+10%)^2 = $165.2

  9. PV of an annuity • Assuming the same annual compound int. rate • Further assume that the corporate bond offer the same annual interest (i.e. $100 p.a.) for a term of three years only (each interest payment is made at the end of each year) • The total PVa is: $100/(1+10%) + • $100/(1+10%)^2 + $100/(1+10%)^3 = $90.91+82.64+75.19 = $248.74

  10. PV of an annuity formula • PVa = $100 { 1/(1+10%)+ 1/(1+10%)^2+ 1/(1+10%)^3} • (1+10%)PVa = $100(1+10%) { 1/(1+10%)+ 1/(1+10%)^2+ 1/(1+10%)^3} • = $100{1+1/(1+10%)+1/(1+10%)^2} • (1+10%)PVa-PVa = $100{1-1/(1+10%)^3)} • (10%)PVa = $100{1-1/(1+10%)^3)} • PVa = $100{1-1/(1+10%)^3)}/(10%) • PVa for n years = $100{1-1/(1+10%)^n)}/(10%)

  11. PV of an annuity formula • PV a=A{1- 1/(1+i )^n}/i • compare with FV a=A{(1+i )^n - 1}/i • In table form, • PV a=A x PVIFA • compare with FV a=A x FVIFA • For an annuity in advance (or annuity due), just multiply (1+i ) to either of the formulae

  12. Discount Cash Flow Valuation • Since most of the securities will provide certain form of future cash flow, their values are determined by the present value of their expected cash flows • In order to compute the PV, we need to know the amount and timing of expected cash flows as well as the required rate of return

  13. Required Rate of Return • The required rate of return (discount rate) is determined by the market • It depends on the market’s perceived level of risk associated with the individual security • E.g. If you can get a 4% annual return from Canadian Saving Bonds, will you required the same rate of return for stock investment

  14. Required Rate of Return cont’ • Strictly speaking, we can break it down into three components • Real Risk-Free Rate • Premium for expected Inflation (Inflation Premium) • Premium for Risk associated with individual security (Risk Premium)

  15. Real Risk-Free Rate • Rate of return on a risk-free security assuming that there is no inflation • it is basically the financial rent the investors charge for using their funds for risk-free investment during non-inflationary period • changes over time • depends on rate of return investors expect to earn on non-inflationary risk-free assets (investors’ expectation) • depends on people’s trade off of current with future consumption (investors’ time preference)

  16. Inflation Premium • investors also expect to be compensated for inflation, i.e., for expected loss in purchasing power • reflects the inflation rate expected in the future • inflation premium on a given security reflects the average inflationexpected over the lifetime of that security • real risk-free rate + inflation premium = risk-free rate e.g. yield on government bonds

  17. Risk Premium • Of primary interest to us are two types of risks: • Business risk - inability of a firm to sustain its competitive position and growth in earnings • Financial risk - inability of a firm to meet its payment obligations as they come due • There are many other types of risks such as maturity risk(e.g yield curve of long-term bond), liquidity risk(e.g real estate investment), etc

  18. Simplified Bond Valuation • Bonds are issued by firms and governments to raise debt capital. Typically, bond issuers pay interest semi-annually at a specified coupon rate. They are frequently denominated in $1000 face values (i.e. the issuer will pay back the bearer $1000 at the maturity date of the bond) • For illustration purpose, let’s assume an annual interest paying bond with a 10% coupon rate. It will mature in 3 years and the market discount rate has just changed to 12%.

  19. Simplified Bond Valuation cont’ • The value of a bond is made up of two different parts: • PV of the interest payments (an annuity cashflow) plus • PV of the principal payment ( a lump sum cashflow)

  20. Relationship between discount rate and coupon rate • Coupon rate is fixed at the time of issuance while the discount rate fluctuates with the market. When the discount rate changes, bond price will also change. • If discount rate is > or < coupon rate, the bond will be sold at a discount (below face value) or at a premium (above face value) • If discount rate is = coupon rate, the bond will be sold at par (at the face value)

  21. Relationship between discount rate and coupon rate cont’ • Annual coupon payment = 1000x10% = 100 • Bond price = 100 x PVIFA (n=3, i=12%) • + 1000 x PVIF (n=3, i=12%) • = 100 x 2.402 + 1000 x 0.712 • = 240.2 + 712 • = 952.2

  22. Actual Bond Valuation: An Application of non-Annual Discounting • A firm issued bonds three years ago with a $1000 face value at a coupon rate of 12 percent. The current yield or yield to maturity on such bonds (i.e. the discount rate to be used, varies with economic conditions) is 10 percent. The bonds have five more years to maturity. What is the current price of such a bond? • The purchaser of the bond gets: • $1000 in 5 years (a lump sum) • coupon payments of 12%/2 x $1000 =$60 every six months

  23. Bond valuation cont’ Discount rate for a (half yearly) period = 10% / 2 = 5% PV0 = $60 PFIVA{5%, 10 periods} + 1000 PVIF{5%, 10 periods} = 60 x 7.722 + 1000 x 0.614 = 463.32 + 614 = $1077.32

  24. Bond valuation cont’ • Six months pass. Interest rates have fallen such that the yield on the bond is now 8 percent. What would the bond be worth? • New price = $60 PVIFA{4%, 9 periods} + 1000PVIF{4%, 9 periods} = $1,149.42 • Note first bond theorem: • Bonds prices vary inversely with interest rates. Increases in rates lead to decreased prices; decreases in rates lead to bond price increases.

  25. Preferred share valuation - application of a perpetual annuity • Preferred shares are issued by firms to raise capital. • These shares pay a fixed expected dividends but not binding as interest on debt. • The principal is not expected to be paid. • In essence, the buyer receives dividends in perpetuity • How to price these securities?

  26. Valuation of Preferred shares • PV of a perpetual cash flow • = A{1- 1/(1+i )^n}/i with n = infinity • = A{1- 0}/i = A/ i • Hence PV of a perpetual preferred shares • = D/Kp • where Kp is the required rate of return for the preferred shares

  27. Valuation of Common Stock • In theory, the value of a share of common stock is equal to the present value of an expected stream of future dividends • Assume a constant growth (g) in dividends • And Ke is the required rate of return for the common shares

  28. Constant Dividend Growth Model • Multiple both sides with (1+Ke)/(1+g) and subtract P again • After munipulation, • Share price (P) = D0(1+g)/(Ke-g) • = D1/(Ke-g) (see proof on p.338)

  29. What have you learnt? • How to calculate the present value of a lump sum investment or saving • How to calculate the present value of a series of equal payments at uniform intervals for a number of periods ( including annuity in advance) • Apply the discount cash flow technique in the valuation of corporate bond (lump sum + annuity), preferred stock (perpetual annuity) and common stock (assuming constant dividend growth)

  30. Effective Annual Rate (EAR) • Often interest is quoted at a nominal rate (an annual rate) but compounded semi-annually or even more frequently • The higher the frequency of compounding, the greater will be the rate of return • That is, the real interest rate is higher than the nominal rate • The real interest rate is named effective annual rate.

  31. Effective Annual Rate cont’ • Suppose an investment account offers a nominal interest rate of 8 percent, compounded quarterly. What is its EAR? • Since 8 percent is an annual rate, interest rate of a quarter will be 8 percent divided by 4 • As it is compounded quarterly, there will be 4 compounding period in a year • EAR = (1+2%)^4 - 1 = 8.24%

  32. General formula for EAR • EAR = (1+i/m)^m - 1 • i = nominal interest rate (an annual rate) • m = the number of compounding periods per year

  33. Real Estate Investment • An illustration of using other people’s money to make money for yourself • Borrow money from the bank - mortgage (lowest interest rate among all types of personal loans) • High gearing return (leverage) • The first thing to buy after you get your first job • A car or a house?

  34. Buy a house at a price of $100,000 • Own money $30,000 • Mortgage loan at a rate of 5% p.a. $70,000 • Total investment $100,000 • Return in a year (rise in house price) 10% • Gross gain $10,000 • Interest expense 70,000 x 5% $3,500 • Net gain $6,500 • Return on your own money $6,500/30,000 = 22%

  35. Mortgage Amortization • Assume the bank lends you $70,000 for 5 years at a fixed rate of 5% (compound annual rate) • Further assume that you are required to pay back the mortgage by annual installments • What will be the annual payment? • How much of each annual payment is interest and how much goes to pay down the mortgage?

  36. How much will be the annual payment? • What type of cash flow is the mortgage from banker’s perspective? • Initial investment = PV = $70,000 • Annual payment = A • PV = A x PVIFA (5 years, 5%) • 70,000 = A x 4.329 • A = 70000/4.329 = 16170

  37. How much of each annual payment is interest?
