  2. 20% effective
  3. 15% effective.

Relate each value to the results in (a), (b) and (c)

 

[3] A finance company has an opportunity to purchase three promissory notes from a broker for a total of $140,000 cash. The first note would pay $20,000 in one year, the second would pay $70,000 in two years and the third $80,000 in three years. The finance company has set for itself a minimum acceptable rate of return of 10% effective.

[15] The Fast Food Co. can expand into either of two locations. Location A will need an expenditure of $130,000 now and will result in a yearly net cash inflow of $35,000 (at the end of each year) for 10 years and no other benefits.

[21] You are operations manager for Flatugas, a small natural gas producer in the Peace River Region of British Columbia. You are considering investing in a new technology that captures more of the gas from the wellhead. The technology will cost $1,000,000 and operating costs are estimated at $25,000 per year payable at the beginning of each year. The technology should result in $250,000 in extra natural gas revenue per year and have the added benefit of reducing greenhouse gas emissions. The technology is expected to last for 5 years when it could be sold back to the manufacturer for a guaranteed price of $249,908.70.

In addition, the company must spend $30,000 today and $30,000 per year for the next 3 years to clear and groom the new area. The life of the lift is estimated to be 11 years with a salvage value of $80,000. Profits from the lift (excluding the cost of grooming and clearing) are expected to be $40,000 per year for the first five years, and $70,000 per year for the next six years. The company wants to earn a minimum of 14% effective on the investment. All revenue occurs at the end of the year and all expenses are paid at the beginning of the year.

[23] A project is to cost $60,000 immediately and to produce net cash flows of $20,000 at the end of the first year, $30,000 at the end of the second year, and $25,000 at the end of the third year. At the end of the third year the business will be sold for $5,000.

  1. If the company requires 15% effective, will it be able to achieve its goal?
  2. Find the value of the bonus paid at the start which would cause the project to earn exactly 20% effective.

 

[24] Due to a restricted capital budget, a company can undertake only one of the following 3-year projects. Both require an initial investment of $650,000 and will have no significant salvage value at the end. Project X is anticipated to have annual profits of $400,000, $300,000, and $200,000 in successive years, whereas Project Y’s only profit, $1.05 million, comes at the end of year three.

  1. Calculate the IRR of each project. On the basis of their IRRs, which project should be selected?
  2. On the basis of NPV, which project should be selected if the firm wants to earn at least 14% effective on their investment?
  3. On the basis of NPV, which project should be selected if the firm wants to earn at least 11% effective on their investment?

 

 


    1. Final Balance = -$1225, so this investment earns more than 10% effective
    2. Final Balance = $1300, so this investment earns less than 20% effective
    3. Final Balance = $0, so this investment earns exactly 15% effective
    1. NPV = $1,012.40
    2. NPV = -$902.78
    3. NPV = $0
  1. NPV = -$3,861.76.  The deal does not earn 10% effective MARR.
    1. NPV = -$198.90 at 15% effective. The company does not achieve its objective.
    2. The NPV of the cash flows using i = 20% effective is -$5,138.88. To earn 20%, the NPV must = $0. Therefore the size of the bonus must be $5,138.89 to have a net project cost $54,861.11 instead of $60,000.
  2. NPV = $135,994.73
    1. NPV = -$9,985.01 at 12% effective and IRR = 6.8305% for this three year project.
    2. To earn 15% effective, NPV must = $0. Without the subsidy, the NPV at 15% is -$15,101.18. This is the PV of the required subsidy at the end of the third year. Therefore, the subsidy = future value of this amount at 15% in three years or $22,967.01.
  3. NPV = $664,371.70. This is the amount PA can afford to bid.
  4. IRR = 12.7118%
  5. NPV at 15% effective = $6,150.15. TQ will make more than 15% effective. IRR = 19.6004%
  6. NPV = $9,076.27;   IRR = 17.29597% effective.
  7. NPV = $22,476.94 IRR = 10.5635%
  8. NPVs are $100,000, $118,896.51 and $122,241.28 respectively. Offer #3 is the most attractive one at 9% effective.
  9. A 10% bond implies that if the bond is purchased for $1,000, it will generate $100 annual interest, and the bondholder will receive the $1,000 bond investment back at the end of the ninth year. To solve this problem, find the PV of nine annual cash flows of $100 and the $1,000 paid at the end of the ninth year using the target interest rate. a. $761.42 b.         $1,000.00        c.         $1,355.39
  10. NPV = $5,375.37 Yes, the company should purchase the equipment.
  11. NPV for A is $39,162.96 NPV for B is $8,508.47.  Location A has the higher NPV at 16% effective.
    1. 4+136/297 years = 4.46 years
    2. -$17,152.42 ? No, because the NPV is negative.
    3. The NPV is +$1,111.42 which is above zero so you should open a kennel.
    4. $17,152.42
    5. minimum selling price is $255,000 + $33,025.52 = $288,026
    6. 12.12%, No because the IRR is below the minimum acceptable rate of return of 14%.
    1. 4+30/170 = 4.176 years
    2. $16,263.94 Yes buy the business because the NPV is positive (earning more than 16% per year).
    3. Purchase price could increase by up to $16,263.94 to $136,264.
    4. Lowest selling price you could accept is $95,840.
    5. 19.45%/year. This exceeds the required rate of 16%/year so buy business.
    6. Up to a $4,967.16/year decrease in revenue.
    1. NPV = +$6408 .24
    2.  IRR = 16.73%
    3. Yes, undertake the business plan because the NPV is positive and the IRR is 16.73% which exceeds the minimum required return of 15%.
    4. $100,000-$14,822.65=$85,177 is the minimum selling price for the business.
    1. -$18,573.73
    2. 14.77%
    3. No, because the NPV is negative and the IRR = 14.77% < MARR of 20%.
    4. $70,000 + $115,004 = $185,004 is the minimum selling price.
    1. 17.25% > 15% MARR so yes invest.
    2. +$19,413.74. Yes, since the NPV is positive.
    3. $210,952 (rounded to nearest dollar)
    4. $5,791.42/year
    1. 4.25 years so no, it is longer than 4 years.
    2. 9.95% is below 15% so no, do not invest.
    3. -$134,086.89 which is below zero, therefore do not invest
    4. $24,000/year
     
    • NPV =+$7,979.31; yes, undertake the project because the NPV is positive
    • IRR = 14.58% exceeds the MARR of 14%
    • 6.57 years
    • $80,000 -\33,722.42 =$46,277.58 is the minimum salvage value.
     
    • NPV = -$198.90; no, the company does not achieve its objective.
    • The bonus must be $5,138.89 to make the NPV equal zero
     
    1. Project X: 20.8%   Project Y: 17.3% Project X has the higher IRR and should be selected.
    2. NPV: Project X: $66,712           Project Y: $58,720 Project X has the higher NPV and should be selected.
    3. NPV:  Project X: $100,085     Project Y: $117,751 Project Y now has the higher NPV and should be selected.
