We project unit sales for a new householduse laserguided cockroach search and destroy system as follows: 
Year  Unit Sales 
1  97,000 
2  109,000 
3  132,000 
4  138,000 
5  91,000 
The new system will be priced to sell at $435 each. 
The cockroach eradicator project will require $2,200,000 in net working capital to start, and total net working capital will rise to 15 percent of the change in sales. The variable cost per unit is $305, and total fixed costs are $1,700,000 per year. The equipment necessary to begin production will cost a total of $18 million. This equipment is mostly industrial machinery and thus qualifies for CCA at a rate of 20 percent. In five years, this equipment will actually be worth about 20 percent of its cost. 
The relevant tax rate is 35 percent, and the required return is 15 percent. Based on these preliminary estimates, what is the NPV of the project? (Round your intermediate calculations and final answer to 2 decimal places. (e.g., 32.16))

A proposed costsaving device has an installed cost of $600,000. It is in Class 8 (CCA rate = 20%) for CCA purposes. It will actually function for five years, at which time it will have no value. There are no working capital consequences from the investment, and the tax rate is 35 percent. 
a.  What must the pretax cost savings be for us to favour the investment? We require a 11 percent return. (Hint: This one is a variation on the problem of setting a bid price.) (Do not round your intermediate calculations and round your final answer to 2 decimal places. (e.g., 32.16))

b.  Suppose the device will be worth $84,000 in salvage (before taxes). How does this change your answer? (Do not round your intermediate calculations and round your final answer to 2 decimal places. (e.g., 32.16))

A fiveyear project has an initial fixed asset investment of $355,000, an initial NWC investment of $39,000, and an annual OCF of −$38,000. The fixed asset is fully depreciated over the life of the project and has no salvage value. If the required return is 11 percent, what is this project’s equivalent annual cost, or EAC? (Negative amount should be indicated by a minus sign. Do not round intermediate calculations and round your final answer to 2 decimal places. (e.g., 32.16))

You are considering a new product launch. The project will cost $2,300,000, have a fouryear life, and have no salvage value; depreciation is straightline to zero. Sales are projected at 160 units per year; price per unit will be $30,000, variable cost per unit will be $18,500, and fixed costs will be $610,000 per year. The required return on the project is 15 percent, and the relevant tax rate is 36 percent. 
a.  Based on your experience, you think the unit sales, variable cost, and fixed cost projections given here are probably accurate to within ±10 percent. What are the upper and lower bounds for these projections? What is the basecase NPV? What are the bestcase and worstcase scenarios? (Negative amount should be indicated by a minus sign. Round your NPV answers to 2 decimal places. (e.g., 32.16))

b.  Evaluate the sensitivity of your basecase NPV to changes in fixed costs. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places. (e.g., 32.161))

5. Hybrid cars are touted as a “green” alternative; however, the financial aspects of hybrid ownership are not as clear. Consider a 2010 Lexus RX 450h,which had a list price of $5,535 (including tax consequences) more than a Lexus RX 350. Additionally, the annual ownership costs (other than fuel) for the hybrid were expected to be $240 more than the traditional sedan. The mileage estimate was 5.4 litre/100 km for the hybrid and 7.1 for the traditional sedan. 
a.  Assume that gasoline costs $1.75 per litre and you plan to keep either car for six years. How many kilometres per year would you need to drive to make the decision to buy the hybrid worthwhile, ignoring the time value of money? (Do not round intermediate calculations and round your final answer to 2 decimal palces. (e.g., 32.16))

b.  If you drive 14,400 km per year and keep either car for six years, what litre per litre would make the decision to buy the hybrid worthwhile, ignoring the time value of money? (Do not round intermediate calculations and round your final answer to 2 decimal places. (e.g., 32.16))

c1.  Gasoline costs $1.75 per litre and you plan to keep either car for six years. How many kilometres per year would you need to drive to make the decision to buy the hybrid worthwhile?

c2.  If you drive 14,400 kilometres per year and keep either car for six years, what price per litre would make the decision to buy the hybrid worthwhile?
