Q3: (45 points) Dima's Company purchased a new machine that costs $300,000 and has a useful life of 7 years. (a) (5 points) Assume that the salvage value of this machine at the end of its useful life is $20,000. Using Straight-Line (SL) method of book depreciation, calculate the depreciation amount and book value of the machine for each year during its useful life. (b) (5 points) Assume that the salvage value of this machine at the end of its useful life is $20,000. Using double-declining balance (DDB) method of book depreciation, calculate the depreciation amount and book value of the machine for each year during its useful life. (c) (5 points) Assume that salvage value of this machine at the end of its useful life is $3,000. Using double-declining balance (DDB) method of book depreciation, calculate the depreciation amount and book value of the machine for each year during its useful life. (d) (5 points) Suppose that this machine is classified as a 7-year MACRS Property (i.e., zero salvage value at the end of its useful life, and half year convention). Derive the 7 -year MACRS Depreciation Rates. Show all your work for full credit. Use the 7-year MACRS Depreciation Rates to answer (e), (f) and (g). If you couldn't do part (d), you can directly use the 7 -years MACRS table from the lecture notes. (e) (10 points) Assume that the company had a gross income of $500,000 at the end of the first year the new machine is purchased. The cost of goods sold was $80,000, labor cost was $90,000 and also additional expenses in the amount of $20,000 occurred in the first year. What will be the taxable income of the company at the end of the first year? (f) (5 points) If the tax rate is 34%, what is the net income of the company at the end of the first year? (g) (10 points) Now, assume that this machine increased in value in years, and the salvage value of the machine in year 3 is estimated to be $320,000. If the machine is to be sold in year 3 , compute the amount of gains (loss) and net proceeds from this sale. (Note that capital gains are taxed at 40% and ordinary gains are taxed at 34%.)
