Tibble Corporation uses straight-line depreciation, prepares adjusting entries annually, and has a December 31 year end. It purchased equipment on January 1, 2014, for $200,000. The equipment had an estimated useful life of five years and a residual value of $20,000. On December 31, 2015, the company tests for impairment and determines that the equipment's recoverable amount is $100,000.

(a) Assuming annual depreciation has already been recorded at December 31, calculate the equipment's carrying amount at December 31, 2015.

(b) Calculate the amount of the impairment loss, if any.
