1.St. Johns River Shipyards is considering the replacement of an 8-year-old riveting machine with a new one that will increase earnings before depreciation from $27,000 to $56,000 per year. The new machine will cost $82,500, and it will have an estimated life of 8 years and no salvage value. The new riveting machine is eligible for 100% bonus depreciation at the time of purchase. The applicable corporate tax rate is 25%, and the firm's WACC is 12%. The old machine has been fully depreciated and has no salvage value.

2.The Dauten Toy Corporation uses an injection molding machine that was purchased prior to the new tax legislation. This machine is being depreciated on a straight-line basis, and it has 6 years of remaining life. Its current book value is $2,100, and it can be sold for $2,400 at this time. Thus, the annual depreciation expense is $2,100/6 = $350 per year. If the old machine is not replaced, it can be sold for $500 at the end of its useful life.

Dauten is offered a replacement machine which has a cost of $10,000, an estimated useful life of 6 years, and an estimated salvage value of $800. The replacement machine is eligible for 100% bonus depreciation at the time of purchase. The replacement machine would permit an output expansion, so sales would rise by $800 per year; even so, the new machine's much greater efficiency would cause operating expenses to decline by $1,500 per year. The new machine would require that inventories be increased by $2,500, but accounts payable would simultaneously increase by $500. Dauten's marginal federal-plus-state tax rate is 25%, and its WACC is 11%.
