1. Present Value: Calculations and Interpretation Classes 3 & 4: March 5 and 7 (LA) and March 1 and 6 (OCC)

2. From last classes . . . What should be the goal of financial managers? What do we need to know to pursue goal? How can we assess progress towards that goal? What is a firm?s market value? Market cap? How do we compute them?

3. Overview: Classes 3 to 6 Discounted present value: basic tool given projections of cash flows and discount rate Present value and wealth creation One and multi-period cash flows Patterns in cash flows = formulas Applications to valuation: bonds Application to valuation: stocks To be addressed later: projecting cash flows, choosing a discount rate

4. Determinants of Value Cash, Time, Risk determine value Present value analysis deals with the effect of time or timing on value Cash flow estimation is the subject of the next part of the course (classes 5 to 8) Risk is incorporated in the discount rate that we discuss in Part 3 of the course In discussing present value analysis now, we assume that cash flows and discount rates are given

5. Emphasis on Present Values Chapter 4 raises a number of topics relevant to the calculation of present values: Simple versus compound interest Compounding interval Continuous compounding Future values Calculation of number of periods of cash flows to achieve a given present or future value We will not emphasize these issues, we concentrate on basic present value calculations

6. Present Value of Cash Flows Calculation of present values is key technique to assign values Present value calculations are applications or simplications of two basic formulas: PV of single cash flow = PV of multiple cash flows =

7. Calculation of Present Values

8. Examples / Applications U. S. Treasury strip prices are examples of market determined discount factors for default-risk free cash flows The structure of present value tables like those in the text (A.1 and A.2) are very straightforward Time in discounting in in terms of periods, usually one year, but often shorter intervals Compounding interval will affect present or future values

9. Present Value Calculations Present values can be calculated using present value tables and paper, calculators and paper, routines programmed into calculators, and spreadsheets All correct methods produce the same answers There is often more than one way to calculate the answers using formulas or individual cash flows but, if correct, they are all mathematically equivalent

10. Example of Three Approaches Present value of $1000 received at the end of each year for five years discounted at 10% Three (at least) ways produce same answer:

11. Characteristics of Present Value Present value calculations are non-linear in the discount rate and growth rates, means changes in present values are not proportional to changes in the discount rate Changes in timing or patterns of growth must always be calculated, relying on intuition is dangerous Terminology may be confusing: discount rate, discount factor, interest rate, cost of capital, opportunity cost, and yield all can mean the same thing in a calculation

12. Example of Dangers Change discount rate in previous example to 20% from 10%, PV becomes $2,991, reduced to 78.9% of $3,791 at 10%, not half. Change times to $1,000 for ten years at 10%, PV becomes $6,146, not double. Delay first cash flow by one year, PV reduced by about 10%, or if by three years, PV reduced by about 25%, difference between delay of one or three years is not three times greater.

13. Meaning of Present Value and Equality of Present Values Present Value of $1,000 for five years at 10 percent (Table A.2) $3,790.80 is equivalent to $1,000 at the end of every year for five years at 10 percent Future value of $3,790.80 at end of five years is $3,790.80x(1.10)5=$6,105.12 This is also future value of $1,000 for five years at 10 percent (see Table A.4)

14. Equivalence of Present Value to Annual Cash Flows

15. Example of Future Value

16. Summary of PV/FV Examples Present value is the amount that can replicate cash flows if discount rate is the future interest rate Maximizing present values also maximizes future values if interest rates do not change (in this case, they are equivalent) Present values and future values of different patterns of cash flows will differ from calculations using constant discount rate if interest-rates vary through time

17. Net Present Value Net present value (NPV) is the difference between the present value of the future cash flows and the cost of acquiring the cash flows In most examples, costs are immediate and are not discounted, while cash flows are in the future and must be discounted More generally, costs and benefits may both be discounted if some costs occur in the future Net present value is a measure of how much more something is worth than it costs, or a wealth increase, as we discuss and illustrate later

18. Positive Net Present Values A positive net present value means that future cash flows represent earnings higher than the discount rate Net present value represents the excess returns (returns above the discount or opportunity rate) represented by the future cash flows Net present values represent value added relative to the opportunity rate

19. Seek Simplifying Patterns in Cash Flows for Short-cuts Can always evaluate individual annual cash flows but this is cumbersome Simplest pattern is constant cash flow each year -- First formula to memorize is

20. Useful Present Value Formulas Perpetuity: Growing Perpetuity: Annuity: Growing Annuity:

21. Simple Patterns in Cash Flows Perpetuity = Preferred dividend Growing perpetuity = Approximate cash flows from new products or stock earnings Annuity = Retirement fund or car or mortgage loan payments Growing annuity = Approximate cash flows from investment with limited life or lifetime earnings

22. Graphical Representations Perpetuity: Growing Perpetuity:

23. Graphical Representations Annuity: Growing Annuity:

24. Sources of Present Values Present value of $1 perpetuity at 20% is $5 Present value of $1 annuity for five years at 20% is $2.99 Therefore, present values of $1 from years six to infinity at 20% is $5 minus $2.99 = $2.01 (less than half of $5) Present value of perpetuity growing at 10% starting at $1 and at 20% is $10 Growing over infinite life is valued at $10 minus $5 or $5

25. Graphical Presentation of Four Present Value Formulas

26. Graphical representation of the four important formulas Areas in graph represent parts of future cash flows - Perpetuity = A+B Growing Perpetuity = A+B+C+D+E Annuity = A Growing Annuity = A+C You can solve for value added by a piece of cash flows, for example cash flows after T, by subtracting A from A+B

27. Example: $1 growing at 10% Discounted at 20%

28. Present Value and Net PV (NPV) Present values are calculations assuming expected cash flows and required discount rates Each may differ for different analysts Knowledge and skill about future cash flows Assessment of risk and alternative investments Net present value = Present value - cost Contrast present value with intrinsic value, market value, under-valued and over-valued

29. Use of Present Value Formulas Familiarity with PV formulas important For example, what is future value of constant annual cash flow? Using annuity obtaining (see. p. 840) Relations between present value formulas are really simple

30. Using PV Formulas to Find Rates You can solve for r given PV, in simplest case of perpetuity r = C / PV With a value for g and PV in growth formula, find r also easy and common in stock analysis (we will use later) With annuities and other formulas you can also solve for r although the equations are non-linear requiring searches

31. Present Value and Wealth Wealth = Present value of consumption Wealth = Present value of cash income DWealth = Change in value of consumption = Change in present value of cash income DWealth => Increase in utility from consumption DWealth = Net present value Net present value > 0 => Wealth increased

32. Present Value and MVA/EVA (I) Market value added is how much more assets are worth than they cost MVA is in part the present value of returns above the opportunity rate on investments thus represents management?s ability to find investments better than alternatives EVA represents the returns above the opportunity rate and is a measure of management?s superior investment strategy

33. Present Value and MVA/EVA (II) Market values represent present value of expected future cash flows If market value is above acquisition cost (MVA), management is expect to produce cash flows are above opportunity rate levels Excess returns (EVA) can be from existing investments and future growth opportunities or growth options

34. Present Value Summary Present values represent cash amounts that can reproduce a pattern of cash flows in the future given the discount rate Two equal present values can represent different patterns of future cash flows Future values and present values are equivalent measures of value given the discount rate Net present values are measures of the increase in wealth representing increased utility from increases in present and future consumption

35. Present Value Analysis: Review Objectives Vocabulary Problem Assignments Relation to syllabus and requirements

36. Basic Steps to Valuation in Finance Estimate cash flows (CASH, TIME) Easy or hard depending on asset Look for patterns in cash flows Choose a discount rate (TIME, RISK) Risk adjusted Opportunity cost Calculate present value and net present value

37. Valuation in Finance Applies to all investment opportunities, including investments in fixed plant and equipment starting a new business selling a line of business (spin-off) buying an existing business values of bonds and stocks real estate investments Used by financial managers, stock and bond analysts, real estate investors
