We received a comment from one of the auditors regarding our depreciation of the new industrial soda machine that we purchased for $100,000 on January 1, 2018. Our original estimate was that the machine has a $15,000 residual value and a useful life of 10 years. We use the straight-line method to record depreciation. However, on January 1, 2020 (i.e., after 2 years), we realize that the machine has a remaining useful life of 7 years and a new residual value is $13,000. A depreciation schedule would show depreciation expense for 2020 $8.500 O $10,000 O $11,850 O $14,000
