Quality
investment with less risk preferable to one with more risk. “likelihood of payback” if both have equal rates of return the one with less risk is preferable
33
quantity
assume risks are equal, timing is identical, investment w/higher rate of return is preferable
at what rate is the investment earning or growing?
34
timing
when and/or how often must cash be put in and/or taken out of an investment
35
Drawback: Results of quantitative only as good as information provided
Garbage in garbage out
36
Net Present Value
Compares the outflow required at time zero, with the Present Value of future cash inflows discounted at the appropriate discount rate
37
Firm’s cost of capital
discount rate used to calculate the present value of future inflows
38
Investor’s opportunity rate
DISCOUNT RATE used to calculate the present value of the future cash inflows
39
How to know if NPV is positive?
if the PV of future cash inflows exceeds the outflow at time zero
40
What does it mean when NPV is positive?
the project or investment would increase the investor’s wealth if undertaken
41
What if the NPV is negative?
would reduce the investors wealth “destroy wealth”
42
Is NPV before tax or after tax?
After-tax cash flows
After-tax interest rate
43
Cash flows recorded annually when doing a TVM calc.
even if they occur monthly
44
When do we record cash flows as occurring?
At the end of the period
45
g CFo
Outflow at zero time
46
g CFi
records annual cash flows from year 1,2,3…
47
g Nj
repeat prior cash flow
48
f NPV
calc net present value after all entries are made
49
First step in calculating NPV?
make a number line
50
Internal Rate of Return
specific interest rate that that equates the present value of future cash flows to the out flow at time zero.
Forces NPV of an investment to zero
51
NPV and IRR use the same what
cash flows
52
What interest rate sets NPV to zero?
Internal Rate of Return
53
Discounted Cash Flow Methods
Net Present Value
Internal Rate of Return
54
How to enter repeat prior cash flow
# g Nj
ex. 3 g Nj
55
Other IRR calculations
Yield to Maturity, Yield to Call
56
Another name for IRR
dollar weighted return
57
First flaw in IRR
-possible to obtain MORE THAN ONE RESULT. (less severe flaw)
-happens when a project has a LARGE OUTFLOW during or toward the end of the project
58
IRR Reinvestment assumption
Assumes you can reinvest future cashflows at rate equal to IRR
-major flaw
59
When is IRR greater than Opportunity Rate
when NPV > 0
60
When is IRR less than opportunity rate?
when NPV < 0
61
When does IRR = NPV
when NPV = 0
62
If NPV is positive, you expect IRR to be
greater than the investors opportunity rate
63
When would you reject a project?
If the NPV is negative or the IRR less than opportunity rate
64
When would you accept a project?
If the NPV is positive or the IRR is greater than the opportunity rate
65
Can you solve for NPV and IRR at the same time?
Yes, you can use one session in your calculator since NPV and IRR are related
66
When you have 2 projects and conflicting NPV and IRR, which do you go with?
NPV. IRR requires all future cash flows be REINVESTED AT IRR RATE. NPV assumes you can only reinvest at the DISCOUNT RATE. This is a more reasonable assumption
67
Ordinary annuity has what vs annuity due?
Lapse of time
68
In a practical situation the goal is not to calculate an exact answer but to do what?
Calculate if a goal can be met. For example retirement in 30 yrs using an i of 8% isn't realistic bc you won't get 8% every year

750k saved @ retirement. what is the monthly annuity payment received be assuming a 30 year period and 5.25% interest
G BEG
N = 360 (12 x 30 = 360))
i = .4375
PV = CHS 750000
PMT = 4,123.4875
FV = LEAVE BLANK
82
If you have an I that's monthly how do you enter that?
You just hit G i so it divides it by 12 that enters the i
83
If you have an N that's monthly how do you enter that?
enter the period, say 30 years, then hit G N

N 48
PV 20000
i 1.625 (19.5/12)
PMT = 603.29
THEN you take that and multiply by 48 months and subtract the original payment
603.29*48 = 28,975.92 - 20000 = 8,975.92
85
If a balance transfer question asks if there is a balance transfer fee, how do you do that?
You take the outstanding balance and multiply by whatever the fee is and then do the calculation so if 20k and the transfer fee is 3% the balance is 20,600 with the transfer fee

PV = 473,250
n = 360 (30 gN)

To amortize to the 300 payment enter 60 f AMORT RCL PV = 433,015
88
Say you’re contributing to a plan for 10 years and then you stop, but that money continues to grow, how do you do that?
The first calculation is going to have a PMT for 10 years, but then its a separate calculation of just future value without a payment
89
Say a bond has a par value of 1000 and you receive coupon payments of $25? What is your I?
I=5 think 2 $25 semiannual payments is $50 which is 5% of 1000
90
If a bond has a semiannual payment for 5 years what is you N?
N is 10 because you’re getting 2 payments a year
91
If a bond has semiannual payments and the rate is 6% what is your I?
I is 3 because you divide by 2 since its semiannual
92
You have a bond that matures in 5 years paying coupon of $25 and you can reinvest that at 6% how much should you pay for that bond?
N = 10 (2 payments a year for 5 years
I = 3 (6% semiannual)
PV =
FV = 1000
93
MORTGAGES ARE ORDINARY ANNUITY OR ANNUITY DUE?
ORDINARY ANNUITY
YOU USE END
94
After you find payment how do you amortize?
period F AMORT
THIS GIVES YOU THE INTEREST
95
What does AMORT give you?
The interest
96
What does cat eyes give you?
The principal
97
How do you find the interest and principal?
You hit period F AMORT then
Cat Eyes
THEN ADD THOSE TOGETHER
98
After you hit Cat Eyes how do you find the REMAINING Principal?
Hit RCL PV and that will show you how much there is left to pay
99
Bond has a coupon of 4% but is yielding 3.8%
The yield is the I =3.8/2
PMT (coupon) = 20 (4/2 on 1000)
100
What is the coupon payment on a bond?
The rate divided by 2
101
BONDS ARE ALWAYS SEMI ANNUAL
Even if its a zero coupon bond
102

Yes
104
You have a $100 stock that pays $5 year 1, $6 year 2, $7 year 3 and you sell it year 3 for $100 what does the timeline look like
Year 0- ($100)
Year 1 - $5
Year 2 - $6
Year 3 - $117
105
Doing NPV dont forget timeline AND
Year zero
106
When you do NPV you need
-a timeline
-required rate of return is your I
107
Bond has a market price of $910, Pays 11% coupon and matures in 6 years
N= 12
PV = 910
PMT = 1000 * .11 = $110/2 = 55
FV = 1000
FIND FOR I
I = 6.6097 * 2 = 13.22
108
Current price of a bond that pays 10% coupon, matures in 8 years, comparable bonds are yielding 12.6%
N = 16
I = 6.3
FV = 1000
PMT = 50
PV = $871.29
109
What is the IRR of a zero coupon bond w/$1000 face value, current price of $810 and will mature in 4 years?
PV = -810
n = 8 (4 * 2)
FV = 1000
PMT = 0
i = 2.6690 * 2 = 5.34
remember its a zero coupon
110

You want to invest $10k a year into a fund that earns 4% a year. You want to make your first investment at the end of year 1, and the last investment at the end of year 3. What is the value at the end of year 4?
First find first 3 years of payments then grow that 1 more yr
N = 3 (your last investment is at end of yr 3)
I = 4
PV = 0
PMT = 10,000 CHS
FV = whatever it is
then FV * 1.04
112
Find after tax savings, assuming 25% marginal tax rate, on a 250k 30 year mortgage at 4.75%
N = 360
I = .3958
PV = 250,000 CHS
PMT = $1304.12
Take PMT times 360 then subtract the original 250k
$469,482.6 - 250,000 = $219,482.6 * .25 = $54,870
THEN take the total minus the savings $469,482.6-$54,870 = $394,559 after tax cost of debt
113
When your finding after tax cost savings, what do you do
Find the total cost of the mortgage, then subtract the original loan amount. That is the total interest, then multiply that by the tax rate. THEN subtract that from the total cost of the mortgage
114
How would you compare interest and principal on a payment?
Find the payment then hit 1 f AMORT to get the interest on 1 payment then hit cat eyes to get the principal
