Instructions: For Computer Lab 2, you should complete the Computer Lab 2 spreadsheet based on the lab instructions. Use your spreadsheet to answer all the questions contained in the lab.

You should type the answers to your questions in the section of the course called “Computer Lab 2 Questions.”

Note: I have included a spreadsheet with the solutions to aid you. Please attempt the lab without using the solutions first.

**Project #1**

Complete the cash flow projections and find the NPV for this project. Initial CAPX are $20,000 and depreciated on a 10-year MACRS schedule. Net working capital required is $5,000 (just a one-time increase) over the life of the project. Incremental sales are $22,000 per year and incremental operating expenses are $18,000 per year. Assume that plant and equipment is disposed of at the end of year 7 (it has no resale value). The tax rate is 30%. Assume a discount rate of 9.3%.

Note that the spreadsheet is set up so that assumptions (things you can change later) go in the yellow cells, and that the other cells contain formulas based on the assumptions.

1.** Assumptions. **Fill in the assumptions section first. Put in the tax rate across the whole row. Put in the MACRS percentages. (The quickest way to do this is to copy them from the MACRS schedule, then go to where you want to paste the values, select Paste Special, click on Values and Transpose, and hit OK.) Enter the discount rate and the resale value.

2. **Balance sheet items.** I find the cash flow projections are easier if we track two balance sheet items, net working capital and net PPE (that is, net fixed assets). In the NWC line, enter the amount that will be required for the project in each year. Note that the NWC must be in place by (the end of) year 0 and would be gone by (the end of) year 7. Keep in mind that this line is the level of NWC in each year, not the change in NWC.

In the net PPE line, we are going to track the book value of the assets we acquire for this project. In the yellow cell (year 0), put the amount of the initial CAPX. In subsequent years, the net PPE will be net PPE from the previous year minus depreciation from that year. (Go ahead and enter this formula even though depreciation isn’t entered yet.)

3. **Getting EBIT(1 − t)**. Enter sales and expense for years 1–7. Enter depreciation expense for each year, which is the initial value of PPE times the MACRS percentage for that year. Enter the formula for EBIT, which is sales less expenses and depreciation. Enter taxes, which is the tax rate times EBIT, and then enter the formula for EBIT(1 − t).

4. **CAPX. **In year 0, CAPX is just equal to the initial value of our PPE, so just enter a formula that references that cell.

The other thing we want to account for here is selling PPE at the end of the project. Put this in the next line below CAPX. In year 7 we get a cash inflow from selling the equipment for resale value (RV), and the we also pay taxes on the gain over book value (BV). Here the RV is given in the assumptions, and the BV is the value of Net PPE in year 7. So enter a formula in year 7 under CAPX that reflects RV−(RV−BV)*t where t is the tax rate.

5. **Change in NWC**. For the change in NWC for year 0, we just make it equal to the initial amount of NWC in year 0 from above. For years 1–7, the change in NWC is just that year’s NWC minus the previous year’s NWC.

6. **Cash Flows.** Now we’re ready to calculate cash flow each year, and all we do is apply our cash flow formula: EBIT(1−t)+Dep.−CAPX−Ch.NWC. Enter this formula and copy it across for all years 0–7. Then the only change necessary is to also add in the sale of PPE in year 7 to the year 7 cash flows.

7. **NPV. **Now enter the formula for NPV on the last line. Remember that the NPV function in Excel discounts the first value by one year, so don’t put the initial cash flow inside the NPV function. Add this in separately.

**Question 1: **What is the NPV of the project under the given assumptions?

**Question 2: **How low would the initial investment have to be in order to make this project acceptable? (Use Goal Seek. Set the NPV to a value of 0 by changing the initial investment in B12. An NPV of 0 makes the project just acceptable.)

**Project #2**

This time we won’t go through the spreadsheet step by step. You are given the assumptions, and you must complete the projections on your own.

**1. Projecting cash flows. **Complete the cash flow projections for project #2. Assume the following:

– The project has a 10-year life.

– Revenues are $70,000 in year 1 and increase $5,000 per year thereafter.

– Operating expenses are 70% of revenues in each year.

– Initial equipment purchases are $100,000 and will depreciated on a seven-year MACRS schedule.

– Equipment purchased will have a resale value of $30,000 at the end of the project.

– The tax rate is expected to be 35% over the life of the project.

– The discount rate for the project is 11.5%.

– Net working capital of $25,000 will need to be maintained over the life of the project.

2. **Finding the NPV.** Use the NPV function to find the NPV of the project.

**Question 3: **Under the above assumptions, what is the NPV of this project?

**3. Finding the IRR (in two ways). **Use the Goal Seek tool to find the internal rate of return on this project. Recall that the IRR is the discount rate that makes the NPV=0. So in Goal Seek set the NPV to 0 by changing the discount rate. After finding the IRR using Goal Seek, verify the IRR using the IRR function (enter on line 31, below the NPV).

**Question 4: **What is the IRR under the above assumptions?

**4. Sensitivity analysis.** Note on the spreadsheet that all yellow cells are assumptions that you can modify. Return the discount rate back to 11.5%. Now find the NPV of this project under the following alternative assumptions (change only one at a time, then change back before going to the next one).

**Question 5: **Initial equipment purchases are $115,000. ________

**Question 6: **Sales in year 1 are only $60,000, but still rise by $5,000 thereafter. ________

**Question 7: **The equipment has no resale value. ________

**Question 8:** The discount rate is 13%. ________

**5. Creating a data table. **Do some additional sensitivity analysis by creating a data table. Create a Data Table showing what the NPV would be with discount rates of 8%, 10%, 12%, 14%, and 16%. Enter the discount rates in a row (for example, in C33:G33). In the cell down and to the left (such as B34) enter the reference for the cell containing the NPV (such as B30). Then to create the Data Table, highlight a block that includes all the cells you just entered (two rows and six columns) and click on Table in the top menu under Data (for Microsoft Office 2007, choose Data>What-if-Analysis>Data Table). The row input cell is the cell where you would input the discount rate (such as B7). Click on OK, and you will have a table showing the NPV under different assumptions.

**Question 9:** According to your table, what would the NPV be if the discount rate were 14% and initial CAPX were $110,000? (Change initial CAPX in B12 before answering.)

**9. Accounting for straight-line depreciation.** Change the depreciation method to straight line. Assume a 10-year life. Recall that straight line would be the same each year: (initial book value-salvage value)/life. Assume a salvage value of 0.

**Question 10: **What is the NPV of the project with straight-line depreciation (under all other initial assumptions in #1)?

**10. Creating a switch (advanced/optional). **You can make it easy to switch back and forth between straight-line and MACRS with a switch. Put the switch in a new row in the assumptions area (e.g., line 9). In the first cell (e.g., A9), put the label “Depreciation method (MACRS=1)”. Then in the next cell (e.g., B9) you will enter a 1 if you want the depreciation method to be MACRS, and you’ll enter something other than 1 if you want the depreciation method to be straight line. Now comes the hard part. On row 17, where you have Depreciation, you must enter an IF function in each cell. IF functions look like this: =IF (condition to check, formula if condition is true, formula if condition is false). So you enter three arguments in each IF function. In this case, it would be something like =IF (B9=1, enter MACRS formula, enter straight-line formula). If you enter this correctly and lock in the right cells, you only have to enter one formula, which you can then copy all the way across the row.
