Summary and Conclusions

This chapter has introduced you to the basic principles of present value and discounted cash flow valuation.In it, we explained a number of things about the time value of money, including these:

For a given rate of return, we can determine the value at some point in the future of an investmentmade today by calculating the future value of that investment.

1.

We can determine the current worth of a future cash flow or series of cash flows for a given rate ofreturn by calculating the present value of the cash flow(s) involved.

2.

The relationship between present value (PV) and future value (FV) for a given rate r and time t is givenby the basic present value equation:

PV = FVt

/(1 + r)

t

As we have shown, it is possible to find any one of the four components (PV, FVt

, r, or t) given theother three.

3.

The principles developed in this chapter will figure prominently in the chapters to come. The reason for thisis that most investments, whether they involve real assets or financial assets, can be analyzed using thediscounted cash flow (DCF) approach. As a result, the DCF approach is broadly applicable and widely usedin practice. Before going on, therefore, you might want to do some of the problems that follow.

Calculating Future Values Assume you deposit $10,000 today in an account that pays 6 percentinterest. How much will you have in five years?

5.2

Calculating Present Values Suppose you have just celebrated your 19th birthday. A rich uncle has setup a trust fund for you that will pay you $150,000 when you turn 30. If the relevant discount rate is 9percent, how much is this fund worth today?

Calculating Rates of Return Youve been offered an investment that will double your money in 10years. What rate of return are you being offered? Check your answer using the Rule of 72.

5.4

Calculating the Number of Periods Youve been offered an investment that will pay you 9 percentper year. If you invest $15,000, how long until you have $30,000? How long until you have $45,000?ANSWERS TO CHAPTER REVIEW AND SELF-TEST PROBLEMS

5.1

We need to calculate the future value of $10,000 at 6 percent for five years. The future value factor is:1.065

= 1.3382

The future value is thus $10,000 1.3382 = $13,382.26. 5.2

We need the present value of $150,000 to be paid in 11 years at 9 percent. The discount factor is:1/1.0911 = 1/2.5804 = .3875

The present value is thus about $58,130. 5.3

Suppose you invest $1,000. You will have $2,000 in 10 years with this investment. So, $1,000 is theamount you have today, or the present value, and $2,000 is the amount you will have in 10 years, or thefuture value. From the basic present value equation, we have:

From here, we need to solve for r, the unknown rate. As shown in the chapter, there are severaldifferent ways to do this. We will take the 10th root of 2 (by raising 2 to the power of 1/10):

IEB Wireframe http://textflow.mheducation.com/parser.php?secload=P3.5.f&fake&print2 of 6 7/23/2016 12:24 PM

Using the Rule of 72, we have 72/t = r%, or 72/10 = 7.2%; so, our answer looks good (remember thatthe Rule of 72 is only an approximation).

5.4

The basic equation is this:

If we solve for t, we find that t = 8.04 years. Using the Rule of 72, we get 72/9 = 8 years, so once againour answer looks good. To get $45,000, verify for yourself that you will have to wait 12.75 years.Page 146

CONCEPTS REVIEW AND CRITICAL THINKING QUESTIONS

1. Present Value [LO2] The basic present value equation has four parts. What are they?2. Compounding [LO1, 2 What is compounding? What is discounting?

Compounding and Period [LO1, 2] As you increase the length of time involved, what happens tofuture values? What happens to present values?

3.

Compounding and Interest Rates [LO1, 2] What happens to a future value if you increase the rate r?What happens to a present value?

4.

Ethical Considerations [LO2] Take a look back at Example 5.7. Is it deceptive advertising? Is itunethical to advertise a future value like this without a disclaimer?

Use the following information for the next five questions:

On March 28, 2008, Toyota Motor Credit Corporation (TMCC), a subsidiary of Toyota Motor, offeredsome securities for sale to the public. Under the terms of the deal, TMCC promised to repay the ownerof one of these securities $100,000 on March 28, 2038, but investors would receive nothing until then.Investors paid TMCC $24,099 for each of these securities; so they gave up $24,099 on March 28,2008, for the promise of a $100,000 payment 30 years later.

5.

Time Value of Money [LO2] Why would TMCC be willing to accept such a small amount today($24,099) in exchange for a promise to repay about four times that amount ($100,000) in the future?6.

Call Provisions [LO2] TMCC has the right to buy back the securities on the anniversary date at a priceestablished when the securities were issued (this feature is a term of this particular deal). What impactdoes this feature have on the desirability of this security as an investment?

7.

Time Value of Money [LO2] Would you be willing to pay $24,099 today in exchange for $100,000 in30 years? What would be the key considerations in answering yes or no? Would your answer depend8.

on who is making the promise to repay?

Investment Comparison [LO2] Suppose that when TMCC offered the security for $24,099, the U.S.Treasury had offered an essentially identical security. Do you think it would have had a higher or lowerprice? Why?

9.

Length of Investment [LO2] The TMCC security is bought and sold on the New York StockExchange. If you looked at the price today, do you think the price would exceed the $24,099 originalprice? Why? If you looked in the year 2019, do you think the price would be higher or lower thantodays price? Why?
