13-9 At the beginning of 2008, Bellamy Seafood acquired equipment costing $60,000. It was estimated that this equipment would have a useful life of six years and a residual value of $6,000 at that time. The straight-line method of depreciation was considered the most appropriate to use with this type of equipment. Depreciation is to be recorded at the end of each year. During 2010 (the third year of the equipments's life), the company's engineers reconsidered their expectations and estimated that the equipment's useful life would probably be seven years (in total) instead of six years. The estimated residual value was not changed at that time. How ever, during 2013 the estimated residual value was reduced to $3,000.
