**Multiple Uneven Cash Flows – Using the Calculator**

Another way to use the financial calculator for uneven cash flows is to use the cash flow keys Texas Instruments BA-II Plus Press CF and enter the cash flows beginning with year 0 You have to press the “Enter” key for each cash flow Use the down arrow key to move to the next cash flow The “F” is the number of times a given cash flow occurs in consecutive years Use the NPV key to compute the present value by entering the interest rate for I, pressing the down arrow and then compute Clear the cash flow keys by pressing CF and then CLR Work The next example will be worked using the cash flow keys. Note that with the BA-II Plus, the students can double check the numbers they have entered by pressing the up and down arrows. It is similar to entering the cash flows into spreadsheet cells. Other calculators also have cash flow keys. You enter the information by putting in the cash flow and then pressing CF. You have to always start with the year 0 cash flow, even if it is zero. Remind the students that the cash flows have to occur at even intervals, so if you skip a year, you still have to enter a 0 cash flow for that year. © 2013 McGraw-Hill Ryerson Limited

Decisions, Decisions LO1 Your broker calls you and tells you that he has this great investment opportunity. If you invest $100 today, you will receive $40 in one year and $75 in two years. If you require a 15% return on investments of this risk, should you take the investment? Use the CF keys to compute the value of the investment CF; CF0 = 0; C01 = 40; F01 = 1; C02 = 75; F02 = 1 NPV; I = 15; CPT NPV = 91.49 No – the broker is charging more than you would be willing to pay. You can also use this as an introduction to NPV by having the students put –100 in for CF0. When they compute the NPV, they will get – You can then discuss the NPV rule and point out that a negative NPV means that you do not earn your required return. You should also remind them that the sign convention on the regular TVM keys is NOT the same as getting a negative NPV. © 2013 McGraw-Hill Ryerson Limited

Quick Quiz – Part I LO1 Suppose you are looking at the following possible cash flows: Year 1 CF = $100; Years 2 and 3 CFs = $200; Years 4 and 5 CFs = $300. The required discount rate is 7% What is the value of the cash flows at year 5? What is the value of the cash flows today? What is the value of the cash flows at year 3? The easiest way to work this problem is to use the uneven cash flow keys and find the present value first and then compute the others based on that. CF0 = 0; C01 = 100; F01 = 1; C02 = 200; F02 = 2; C03 = 300; F03 = 2; I = 7; CPT NPV = Value in year 5: PV = ; N = 5; I/Y = 7; CPT FV = Value in year 3: PV = ; N = 3; I/Y = 7; CPT FV = Using formulas and one CF at a time: Year 1 CF: FV5 = 100(1.07)4 = ; PV0 = 100 / 1.07 = 93.46; FV3 = 100(1.07)2 = Year 2 CF: FV5 = 200(1.07)3 = ; PV0 = 200 / (1.07)2 = ; FV3 = 200(1.07) = 214 Year 3 CF: FV5 = 200(1.07)2 = ; PV0 = 200 / (1.07)3 = ; FV3 = 200 Year 4 CF: FV5 = 300(1.07) = 321; PV0 = 300 / (1.07)4 = ; PV3 = 300 / 1.07 = Year 5 CF: FV5 = 300; PV0 = 300 / (1.07)5 = ; PV3 = 300 / (1.07)2 = Value at year 5 = = Present value today = = (difference due to rounding) Value at year 3 = = © 2013 McGraw-Hill Ryerson Limited

**Annuities and Perpetuities 6.2**

LO1 Annuity – finite series of equal payments that occur at regular intervals If the first payment occurs at the end of the period, it is called an ordinary annuity If the first payment occurs at the beginning of the period, it is called an annuity due Perpetuity – infinite series of equal payments © 2013 McGraw-Hill Ryerson Limited

**Annuities and Perpetuities – Basic Formulas**

LO1 Perpetuity: PV = C / r Annuities: © 2013 McGraw-Hill Ryerson Limited

21
**Annuities and the Calculator**

LO1 You can use the PMT key on the calculator for the equal payment The sign convention still holds Ordinary annuity versus annuity due You can switch your calculator between the two types by using the 2nd BGN 2nd Set on the TI BA-II Plus If you see “BGN” or “Begin” in the display of your calculator, you have it set for an annuity due Most problems are ordinary annuities Other calculators also have a key that allows you to switch between Beg/End. Warn students to be careful with this function. Every term, it seems that there is always one student who, during the midterm exam, switches their calculator to beginning of period payments and forgets to switch it back for the next question. Another way of handling the annuity due calculation is to calculate it as if it were a regular annuity, and then simply multiply the answer given by (1+R). © 2013 McGraw-Hill Ryerson Limited

Quick Quiz – Part II LO1 You know the payment amount for a loan and you want to know how much was borrowed. Do you compute a present value or a future value? You want to receive $5,000 per month in retirement. If you can earn 0.75% per month and you expect to need the income for 25 years, how much do you need to have in your account at retirement? Calculator PMT = 5000; N = 25*12 = 300; I/Y = .75; CPT PV = 595,808 Formula PV = 5000[1 – 1 / ] / = 595,808 © 2013 McGraw-Hill Ryerson Limited

**Annuity Due – Example 1 continued**

LO1 Formula Approach FV = 10,000[(1.083 – 1) / .08](1.08) = 35,061.12 Calculator Approach 2nd BGN 2nd Set (you should see BGN in the display) 3 N -10,000 PMT 8 I/Y CPT FV = 35,061.12 2nd BGN 2nd Set (be sure to change it back to an ordinary annuity) Note that the procedure for changing the calculator to an annuity due is similar on other calculators. What if it were an ordinary annuity? FV = 32,464 (so receive an additional by starting to save today.) Remind students to change their calculator back to the regular annuity setting before proceeding with other questions! © 2013 McGraw-Hill Ryerson Limited

Perpetuity – Example 1 LO1 The Home Bank of Canada want to sell preferred stock at $100 per share. A very similar issue of preferred stock already outstanding has a price of $40 per share and offers a dividend of $1 every quarter. What dividend would the Home Bank have to offer if its preferred stock is going to sell? © 2013 McGraw-Hill Ryerson Limited

32
**Perpetuity – Example 1 continued**

LO1 Perpetuity formula: PV = C / r First, find the required return for the comparable issue: 40 = 1 / r r = .025 or 2.5% per quarter Then, using the required return found above, find the dividend for new preferred issue: 100 = C / .025 C = 2.50 per quarter This is a good preview to the valuation issues discussed in future chapters. The price of an investment such as a stock is just the present value of expected future cash flows. © 2013 McGraw-Hill Ryerson Limited

Quick Quiz – Part IV LO1 You want to have $1 million to use for retirement in 35 years. If you can earn 1% per month, how much do you need to deposit on a monthly basis if the first payment is made in one month? What if the first payment is made today? You are considering preferred stock that pays a quarterly dividend of $1.50. If your desired return is 3% per quarter, how much would you be willing to pay? Q1: 35(12) = 420 N; 1,000,000 FV; 1 I/Y; CPT PMT = 1,000,000 = C ( – 1) / .01 C = Q2: Set calculator to annuity due and use the same inputs as above. CPT PMT = 1,000,000 = C[( – 1) / .01] ( 1.01) C = Q3: PV = 1.50 / .03 = $50 © 2013 McGraw-Hill Ryerson Limited
