Problem A$7-2($Variation$)$

A project manager is evaluating whether it is economical to develop a project requiring expenditures at time zero of $$200,000$ for land, $$300,000$ for inventory working capital, $$800,000$ for a steel building, $$240,000$ for equipment, and $$60,000$ for vehicles. Starting in year one the manager estimates that production will generate annual end$-$of$-$year escalated revenue of $$2,800,000$ with escalated operating costs of $$2,300,000.$ Operating costs and revenue will both escalate at a compound interest rate of $10\%$ per year beginning in year two. Use straight$-$line depreciation over $39$ years for the building cost starting in year one assuming the building went into service in August of the year one calendar tax year and use the mid$-$month convention. Use $7-$Year MACRS depreciation rates for the qualifying equipment cost starting in year one with the half$-$year convention and the $5-$Year MACRS rates for the vehicle cost, again, starting in year one with the half$-$year convention.

Calculate the project cash flows for the first four years of this business and the after$-$tax cash flow that would be realized if the business were to be sold at the end of year four for a sale value of $$1,500,000.$ Write off all remaining tax book values at the end of year four to determine taxable gain $($or loss$)$ and treat the sale as ordinary income. For a minimum after$-$tax rate of return of $15\%,$ calculate the project after$-$tax NPV$,$ DCFROR, and PVR$.$ The effective combined federal and state income tax rate is $25\%.$ Other income exists against which to utilize deductions $($expense scenario$).$
