Webmasters.com has developed a powerful new server that would be used for corporations’ Internet activities. It would cost $10 million at Year 0 to buy the equipment necessary to manufacture the server. The project would require net working capital at the beginning of each year in an amount equal to 10% of the year's projected sales; for example, NWC0 = 10%(Sales1). The servers would sell for $24,000 per unit, and Webmasters believes that variable costs would amount to $17,500 per unit. After Year 1, the sales price and variable costs will increase at the inflation rate of 3%. The company’s nonvariable costs would be $1 million at Year 1 and would increase with inflation. The server project would have a life of 4 years. If the project is undertaken, it must be continued for the entire 4 years. Also, the project's returns are expected to be highly correlated with returns on the firm's other assets. The firm believes it could sell 1,000 units per year. The equipment would be depreciated over a 5-year period, using MACRS rates. The estimated market value of the equipment at the end of the project’s 4-year life is $500,000. Webmasters’ federal-plus-state tax rate is 40%. Its cost of capital is 10% for average-risk projects, defined as projects with a coefficient of variation of NPV between 0.8 and 1.2. Low-risk projects are evaluated with a WACC of 8%, and high-risk projects at 13%.

a. Develop a spreadsheet model Key Results: Net operating working capital/Sales 10% NPV = First year sales (in units) 1,000 IRR = Sales price per unit $24, and use it to find the project’s NPV, IRR, and payback. Input Data (in thousands of dollars) Equipment cost $10,000.00 Payback = Variable cost per unit (excl. depr.) $17.50 Nonvariable costs (excl. depr.) $1,000 Market value of equipment at Year 4 $500 Tax rate 40% WACC 10% Inflation in prices and costs 3.0% Estimated salvage value at year 4 $500 Intermediate Calculations 0 1 2 3 4 Units sold Sales price per unit (excl. depr.)

b. Now conduct a sensitivity analysis to determine the sensitivity of NPV to changes in the sales price, variable costs per unit, and number of units sold. Set these variables’ values at 10% and 20% above and below their base-case values. Include a graph in your analysis. % Deviation SALES PRICE Note about data tables. The data in the column input should NOT be input using a cell reference to the column input cell. For example, the base case Sales Price in Cell B86 should be the number $24.00 you should NOT have the formula =D28 in that cell. This is because you'll use D28 as the column input cell in the data table and if Excel tries to iteratively replace Cell D28 with the formula =D28 rather than a series of numbers, Excel will calculate the wrong answer. Unfortunately, Excel won't tell you that there is a problem, so you'll just get the wrong values for the data table! from Base NPV Base Case $24.00 -20% -10% 0% 10% 20% % Deviation VARIABLE COST % Deviation 1st YEAR UNIT SALES from Base NPV from Base NPV Base Case $17.50 Base Case 1,000 -20% -20% -10% -10% 0% 0% 10% 10% 20% 20% Deviation NPV at Different Deviations from Base from Sales Variable Base Case Price Cost/Unit Units Sold -20% $0 $0 $0 -10% $0 $0 $0 0% $0 $0 $0 10% $0 $0 $0 20% $0 $0 $0 Range.
