## Sample Third Quiz

*with some numerical answers*

*and a correction*

Do all the problems. Include calculations and/or explanations in your answers wherever appropriate. More credit will be given for correct reasoning than for correct arithmetic.

1. Alpha Co. is investigating project A with cost of capital k = 6%.

. A: -$5,000, $1,646, $1,646, $1,646, $1,646 * NPV = $704 IRR = 12%*

(a) Calculate its NPV and IRR. Is A acceptable?

(b) Sketch the NPV profile.

2. Beta Co. is looking at Project C with cost of capital k = 7%.

C: $3,000, -$945, -$945, -$945, -$945.

*IRR = 10% but this is a borrowing project with NPV = -$201*

Sketch C’s NPV profile. Is it acceptable? Explain in both NPV and IRR terms.

3. Gamma Co. is looking at Project D with k = 7%.

. D: -$3,000, $2,000, $4,000, $6,000, -$10,000

The spread sheet says the NPV = -$368 but IRR = 15%. Is Project D acceptable? It has a negative NPV but IRR > k. Explain.

4. I am planning on investing for retirement. I estimate that I will need $100,000 per year for twenty years. I expect to earn 7% while accumulating and 3% in retirement. I am now 25 expecting to retire at 70 and have nothing in the plan yet, and from this year I will be contributing equal annual amounts.

. (a) How big must those contributions be?

. (b) I started on that plan ten years ago and am now 35 and have $80,000 in the plan. If I still want the $100,000 per year, what contributions should I make?

. (c) The week after making the calculation in part (b), a market crash causes me to lose 30% of my $80,000. If I go on making the contributions from part (b) and retire two years later, can I still expect at least the $100,000 per year?

4. We are thinking abut buying a widget fogger. It would cost $16,000 to purchase and $4,000 to install. It would be subject to a 5% investment tax credit. The fogger is in the SACRS(20%, 30%, 25%, 25%) class. We would use it for 5 years and sell it for $1,600. The fogger would raise our revenues by $6,000 per year and raise our expenses by $800 per year. **Our tax rate is 20%.**

. (a) Write the depreciation table, and calculate the after-tax cash flow from the sale of the fogger.

. (b) Calculate all the cash flows from the purchase, use, and sale of the fogger.
