Dyke Company's net incomes for the past three years are presented below:

2016	2015	2014
$480,000	$450,000	$360,000

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

1. Dyke 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, 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:

	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, on the January 1, 2016 book value, over the useful life remaining at that time. The depreciation recorded in 2016 was $72,000.

Dyke, in reviewing its provision for uncollectibles during 2014, 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 2016 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.
