Bolt Company purchased equipment on January 1 of Year 1 for $102,000. This equipment has an estimated useful life of five years, a residual value of $12,000, and is depreciated using the sum-of-the-years'-digits method. At the beginning of Year 3, Bolt suspects that the original investment in the asset will not be realized; the total remaining future cash inflow expected to be produced through use of the equipment, including the original residual value, is $30,000. The equipment's fair value at January 1 of Year 3 is $21,000. a. Determine whether the asset is impaired and, if so, the amount of the impairment loss on January 1 of Year 3.
