|-----------|-------------I
$200 “Y” 2400
r = 4%
FV2 = $3032.32
You can use either
Option a) FV formula and bring all cash flows to t=2 or
Option b) PV formula and bring all cash flows to t=0
Option a) Bring all cash flows to t=2 (use FV or compound)
200(1 + r)2 + Y(1 + r)1 + 2400 = 3032.32
200(1.04)2 + Y (1.04) + 2400 = 3032.32
216.32 + Y(1.04) + 2400 = 3032.32
Y(1.04) = 3032.32 – 2400 – 216.32
Y(1.04) = 416
Y = 416 / (1.04)
Y = $400
Option b) Bring all cash flows to t=0 (use PV and discount)
200 + Y/(1 + r)1 + 2400/(1 + r)2 = 3032.32/ (1 + r )2
Y = $400.00
Example 2: Delayed Annuity
Answer A
Using your calculator:
PMT = $100, I = 9, n= 4, Fv =0, COMP PV
 PV = $323.97 at t=1 !!
Bring PV1 to PV0
PV0 = $323.97 / (1.09)1 = $297.22
Example 3: EAR
Answer D
Using your calculator: PMT = $1883.33, n = 12, PV = $20,000, FV=0, Comp “i”
 i= 1.9322%
EAR = (1+.019322)12 -1 = 25.82%
Example 4: Mortgages
Answer D

1
The monthly interest rate is given by:
(1 + im )12 = 1 + EAR = (1 + 3125%)² = 1.076406, that is im = 0.5142%
The monthly payment for the 20-year loan
320,000 = PMT x PVIFA(0.5142%,300)
PMT = $2,095.22
Mortgage remaining at the end of 5 years  240 months remaining:
Using your calculator:
PMt = $2095.22, n=240, i=.5142, Fv=0, COMP PV
 PV = 288,480.10
Example 5: Bonds
Solution
a) Current Yield = Annual Coupon Payment/ Bond Price
Step 1: Find price of bond today (7 years remaining)
Using your calculator:
PMT = 70/2 = 35.00, n = 7 x 2 = 14, FV = 1000, i = 8/2 = 4%, COMP PV
 PV = -947.18
-> Current Yield = $70/$947.18 = 7.39%
Step 2: Find rate of return over holding period (3 years)
b.
Solution B
4-year Rate of Return = [30 x FVIFA(2%,8) + 1,040 – 1,015] / 1,015 = 27.8314% The annual
rate of return is (1+27.8314%)1/4 – 1 = 6.3309%

Example 7
Solution C
Step 1: Determine the initial cash outflow. The payback is 2.25 years, so the cash
flow will be:
CF0 = -[CF1 + CF2 + 0.25(CF3)]
= -[$500 + $300 + 0.25($400)]
= -$900.
Step 2: Calculate the IRR:
CF0 = -900; CF1 = 500; CF2 = 300; CF3 = 400; CF4 = 600; and then solve
for IRR = 33.49% ≈ 33.5%
Example 7B
Answer B
Step 1: Determine the differential cash flows between Projects A and B
Project A Project B ΔCFs
Year Cash Flow Cash Flow A - B
0 -$2,000 -$1,500 -$500
1 700 300 400
2 700 500 200
3 1,000 800 200
4 1,000 1,100 -100
Step 2: Calculate the IRR of the differential cash flows
CF0 = -500; CF1 = 400; CF2 = 200; CF3 = 200; CF4 = -100; and then solve for
IRR = 26.67%

Example 9
Answer D
From the PV CCA Tax Shield formula:
PVCCATS = [(600,000 x .30 x .35)/(.12 + .30)] x [(1 + 0.5 x 0.12)/(1.12)]
= 141,964
Example 10
Answer A
After-tax CFO (excluding CCA) = 240,000 x (1 - 0.35) = 156,000
NPV = -600,000 + 156,000 x PVIFA(12%,4) + 141,964 = 15,791
3530_Final_Tutorial_-_Solutions Updated.docx

Example 11
Answer A
PVCCATS will decrease by: [(50,000 x .30 x .35)/(.12 + .30)] x (1.12)-4 = 7,944
PV(CFO excluding CCATS) will increase by 50,000 x (1.12)-4 = 31,776
So, NPV will increase by 31,776 – 7,944 = 23,832
Example 12A
Answer C
1) In the best-case scenario:
The before-tax profit is
= 12,000(1+10%)$21(1+5%) - 12,000(1+10%)$11(1-3%) - $44,000(1-1%) - $40,000 = $66,656.
The after-tax profit = $66,656(1-34%) = $43,992.96.
The operating cash flow = $43,992.96 + $40,000 = $83,992.96.
The PV of the operating cash flow using an annuity factor of 12% for 2 years is
= $141,952.39.
The NPV is = $141,952.39 - $80,000 = $61,952.39.
2) In the worst-case scenario:
The before-tax profit is
= 12,000(1-10%)$21(1-5%) - 12,000(1-10%)$11(1+3%) - $44,000(1+1%) - $40,000 = $8,656.
The after-tax profit = $8,656(1-34%) = $5,712.96.
The operating cash flow = $5,712.96 + $40,000 = $45,712.96.
The PV of the operating cash flow using an annuity factor of 12% for 2 years is
= $77,257.23.
The NPV is = $77,257.23 - $80,000 = -$2,742.77.
3) The difference in the NPVs = $61,952.39 – (-$2,742.77) ≈ $64,695.
Example 12B
Answer B
Old price = $60/1.2 = $50.
Therefore, variable costs per product = $50 × 0.7 = $35, which equals 58.33% of
the new price. So the new accounting break-even revenue
= $1 million / (1-0.5833)  $2,400,000.

Example 13A: Risk
Answer C
The equal probability is 1/3.
The portfolio expected return = (1/3)(-4% + 2% + 5%) = 1%.
The portfolio variance = (1/3)[(-4%-1%)2 + (2%-1%)2 + (5%-1%)2]
= 14 percentages squared = 0.0014.
Taking the square root of the portfolio variance, we find that the portfolio standard deviation is
3.74%.

Answer B
Expected Return W = 6% + 2.0 x 9% = 24% < 25% => Buy W.
Expected Return X = 6% + 1.6 x 9% = 20.4% > 19% => Do not buy X.
Expected Return Y = 6% + 1.1 x 9% = 15.9% < 17% => Buy Y.
Expected Return Z = 6% + 0.8 x 9% = 13.2% > 11% => Do not buy Z.
Note: You should sell (short) X and Z because they are overpriced by the market
Example 16B
Answer A
Project I: expected return = 0.06 + 2 × 0.09 = 0. 24 < IRR of 0.25.
 Project I plots above the SML and should be accepted.
Project II: expected return = 0.06 + 1.1 × 0.09 = 0. 159 > IRR of 0.15.
 Project II plots below the SML and should be rejected.
