sh.480, 000sh.450, 000sh.360, 000

During the 2019 year-end audit, the following items come to your attention:

1.DK bought a truck on January 1, 2016 for sh.196, 000 with a sh.16, 000 estimated residual 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, DK 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

Straight-line36,00036,00036,000

Double-declining46,08057,60072,000

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 sh.72, 000.

3.DK, in reviewing its provision for uncollectible 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 2018 and 2019 when the expense had been sh.18, 000 and sh.12, 000, respectively. The company recorded bad debt expense under the new rate for 2019. The company would have recorded sh.6, 000 less of bad debt expense on December 31, 2019 under the old rate.
