As at December 31, 2017 Kendrick Corporation is having its financial statements audited for the first time ever. The auditor has found the following items that might have an effect on previous years.

1.Kendrick purchased equipment on January 2, 2014 , for $130,000. At that time, the equipment had an estimated useful life of10years, with a $10,000residual value. The equipment is depreciated on a straight-line basis. On January 2, 2017, as a result of additional information, the company determined that the equipment had a total useful life of seven years with a $6,000residual value.

2.During 2017, Kendrick changed from the double-declining-balance method for its building to the straight-line method because the company thinks the straight-line method now more closely follows the benefits received from using the assets. The current year depreciation was calculated using the new method following straight-line depreciation. In case the following information was needed, the auditor provided calculations that present depreciation on both bases. The building had originally cost $1.2million when purchased at the beginning of 2015 and has a residual value of $120,000. It is depreciated over20years. The original estimates of useful life and residual value are still accurate.2017 /2016 /2015 Straight-line $54,000 /$54,000 /$54,000 Double-declining-balance 2017 /2016 /2015 $ 97,200 /$ 1,08,000/ $1,20,000 ( Hint : Only Two accounts are required for this journal entry)

3.Kendrick purchased a machine on July 1, 2014, at a cost of $160,000. The machine has a residual value of $16,000and a useful life of eight years. Kendrick's bookkeeper recorded straight-line depreciation during each year but failed to consider the residual value. ( Hint : Only Three accounts are required for this journal entry)

4.Prior to 2017, development costs were expensed immediately because they were immaterial. Due to an increase in development phase projects, development costs have now become material and management has decided to capitalize and depreciate them over three years. The development costs meet all six specific conditions for capitalization of development phase costs. Amounts expensed in 2014, 2015, and 2016 were $300, $500, and $1,000, respectively. During 2017, $4,500was spent and the amount was debited to Deferred Development Costs (an asset account). ( Hint : Only Two accounts are required for this journal entry)

Q-1) Prepare the necessary journal entries to record each of the changes or errors. The books for 2017 have been adjusted but not closed. Ignore income tax effects.

Q-2) Calculate the comparative net income amounts for 2016 and 2017, starting with income before the effects of any of the changes identified above. Income before depreciation expense was $60,000 in 2017 and $42,000 in 2016.

Q-3) Calculate the 2017 depreciation expense on the equipment.
