A virtual mold apparatus for producing dental crowns permits an infinite number of shapes to be custom constructed based upon mold imprints taken by dentists. It costs $28,500 and is purchased at the beginning of the tax year. It is expected to last 9 years with no salvage value at that time. The dental supplier depreciates assets using MACRS but values assets of the company using straight-line depreciation. Determine the depreciation allowance and the unrecovered investment for each year using each of the following:

a. For tax purposes (be sure to identify the MACRS-GDS property class) (9.6.2)

b. For company valuation purposes (9.3)
