7. Accounting for changes and error corrections Dyke Company's net incomes for the past three years are presented below (ignore taxes): 2019 2018 $480,000 $450,000 $360,000 2017 During the 2019 year-end audit, the following items come to your attention: 1. Dyke bought equipment on January 1, 2016 for $490,000 with a $40,000 estimated salvage value and a six-year life. The company debited an expense account and credited cash on the purchase date for the entire cost of the asset. (Straight-line method) 2. During 2019, Dyke changed from the straight-line method of depreciating its cement plant to the double-declining balance method. The following computations present depreciation on both bases: 2019 2018 2017 36,000 36,000 36,000 46,080 57,600 72,000 Straight-line Double-declining The net income for 2019 was computed using the double-declining balance method, on the January 1, 2019 book value, over the useful life remaining at that time. The depreciation recorded in 2019 was $72,000 3. Dyke, in reviewing its provision for uncollectibles during 2019, has determined that 1% is the appropriate amount of bad debt expense to be charged to operations. The company had used 1 /2 of 1% as its rate in 2017 and 2018 when the expense had been $18,000 and $12,000, respectively. The company recorded bad debt expense under the new rate for 2019. The company would have recorded $6,000 less of bad debt expense on December 31, 2019 under the old rate.
