Shaftel Ready Mix is a processor and supplier of concrete, aggregate, and rock products. One division of the company operates in the intermountain western United States. Currently, Shaftel has 14 cement-processing plants and a labour force of more than 375 employees. With the exception of cement powder, all raw materials (for example, aggregates and sand) are produced internally by the company. U.S. demand for concrete and aggregates has been growing steadily, and in the west, the growth rate has been above the national average. Because of this growth, Shaftel has more than tripled its gross revenues over the past 10 years. Of the intermountain states, Arizona has been experiencing the most growth. Processing plants have been added over the past several years, and the company is considering the addition of yet another plan (to be located in Scottsdale). A major advantage of having another plan in Arizona is the ability to operate year-round, a feature not found in such states as Utah and Wyoming. In setting up the new plant, land would have to be purchased and a small building constructed. Equipment and furniture would not need to be purchased these items would be transferred from a plan that had been opened in Wyoming during the oil-boom period and closed a few years after the end of that boom. However, the equipment needs some repair and modification before it can be used. It has a book value of $200,000, and the furniture has a book value of $30,000. Neither has any outside market value. Other costssuch as those related to the installation of a silo, a well, electrical hookups, and so onwill be incurred. No salvage value is expected. The summary of the initial investment costs by category is as follows: Land $20,000 Building 135,000 Equipment: Book value 200,000 Modifications 20,000 Furniture (book value) 30,000 Silo 20,000 Well 80,000 Electrical hookups 27,000 General setup 50,000 Total initial outlay $582,000 Estimates concerning the operation of the Scottsdale plant are given below: Life of plan and equipment 10 years Expected annual sales (in cubic yards) 35,000 Selling price (per cubic yard) $45.00 Variable costs (per cubic yard): Cement $12.94 Sand/ gravel 6.42 Fly ash 1.13 Admixture 1.53 Driver labour 3.24 Mechanics 1.43 Plant operations (batching and cleanup) 1.39 Loader operator 0.50 Truck parts 1.75 Fuel 1.48 Other 3.27 Total variable cost $35.08 Fixed costs (annual): Salaries $135,000 Insurance 75,000 Telephone 5,000 Amortization 58,200* Utilities 25,000 Total fixed cost $298,200 *Straight-line amortization is calculated using all initial investment costs over a 10-year period, assuming no salvage value. After reviewing the above data, Karl Flemming, vice-president of operations, argues against the proposed plant. Karl is concerned because the plant would earn significantly less than the normal 8.3 percent return on sales. All other plants in the company are earning between 7.5 and 8.5 percent on sales. Karl also notes that it would take more than five years to recover the total initial outlay of $582,000. In the past, Shaftel has always insisted that an investments payback period be no more than four years. The companys cost of capital is 10 percent. Ignore tax effects. Required: 1. Prepare a variable-costing income statement for the proposed plant. Compute the ratio of net income to sales. Is Karl correct that the return on sales is significantly lower than the company average? 2. Compute the payback period for the proposed plant. Is Karl right that the payback period is greater than four years? Explain. Suppose that you were told that the equipment being transferred from Wyoming could be sold for its book value. Would this affect your answer? 3. Compute the NPV for the proposed plant. 4. Explain to the CEO if this project is viable.

I tried to solve the question as the following for the REq1 and REQ 2

Could you please help what should I choose the assumption from the following two assumptions in my calculation for Req 1 and Req 2?

Assumption a) The plant had a sunk cost for the BV equipment 200,000 and thus in this plant we can remove the 200 000 from the initial 582 000 initial outlay, consequently no depreciation on this equipment except for the improvement

OR

Assumption b ) The former plant sent equipment to this plant at a BV cost of 200,000 and thus the whole 582 000 is an initial cost outlay, and depreciation is divided by 10 years as presented

Thanks

1. Prepare a variable-costing income statement for the proposed plant. Compute the ratio of net income to sales. Is Karl correct that the return on sales is significantly lower than the company average? Assumption: The former plant sent equipment to this plant at a BV cost of 200,000 and thus the whole 582 000 is an initial cost outlay, and depreciation is divided by 10 years as presented Shaftel Ready Mix Income Statement - Variable method For the Propored Plant For the year Ended 20xx - Assume S S 1,575,000 1,227,800 347,200 $ Sales (35,000 x $45) Less: Variable Cost (35,000 x $35.08) Contribution Margin Less: Fixed Cost Salaries Insurance Telephone Amortization Utilities Net Income $ $ $ S S 135,000 75,000 5,000 56,200 25,000 is 296,200 51,000 * The amortization amount includes erroneously $2,000 for the land amortization, since land is not subject to amortization, we need to remove it from the amortization amount. Amortization Amount Calculation: Total initial outlay $ 582,000 Less: Land (not subjct to Amort.) $ 20,000 Amortizable Assets $ 562,000 Divided by: Life of plan and equipment 10 years Amortization 56,200 2. Compute the payback period for the proposed plant. Is Karl right that the payback period is greater than four years? Explain. Suppose that you were told that the equipment being transferred from Wyoming could be sold for its book value. Would this affect your answer? Net Income Add: Amortization Annual Cash Flow $ $ $ 51,000 56,200 107,200 Payback Period = Original Investment** / Annual Cash Flow $352,000 / $107,200 = 3.28 years **Original Investment=Initial Outlay-Book Value (Equipment+Furniture) = $582,000 - $200,000+$30,000) = $352,000 Is Karl right that the payback period is greater than four years? Explain. Answer: Karl is incorrect. Becuase the book value of equipment and furniture should not be included in the initial investment since they do not incur opportunity costs! Suppose that you were told that the equipment being transferred from Wyoming could be sold for its book value. Would this affect your answer? Answer: When the book value is excluded, the investment falls from 582,000 to 352,000. Karl's payback calculation would be correct if the equipment and furniture can be sold at their book value because there would now be an opportunity cost associated with them and the cost should be included in the initial investment
