4. VanDyke Company's net incomes for the past three years are presented below:

2016 = $480,000 2015 = $450,000 2016 = $360,000

During the 2016 year-end audit, the following items come to your attention:

1. VanDyke bought equipment on January 1, 2013 for $392,000 with a $32,000 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 2016, VanDyke 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: 2016 2015 2014 Straight-line 36,000 36,000 36,000 Double-declining 46,080 57,600 72,000 The net income for 2016 was computed using the double-declining balance method. The depreciation recorded in 2016 was $46,080.

3. VanDyke, in reviewing its provision for allowance for doubtful accounts during 2016, 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 2015 and 2014 when the expense had been $18,000 and $12,000, respectively. The company recorded bad debt expense under the new rate for 2016. The company would have recorded $6,000 less of bad debt expense on December 31, 2016 under the old rate.
