The Carowinds Metals Corporation is trying to become more profitable (and maybe improve quality) by adding more efficient welding equipment. Despite the cost, they feel profit can be made if using MACRS depreciation. The current welding machine is 15 years old, fully depreciated, obsolete, and has no salvage value.
