As at December $31,2023,$ Sandhill Corporation is having its financial statements audited for the first time ever. The auditer has found

the following items that might have an effect on previous years.

Sandhill purchased equipment on January $2,2020,$ for $$119,600.$ As that time, the equipment had an estimated useful life of

$10$ years, with a $$9,200$ residual value. The equipment is depreciated on a straight$-$line basis. On January $2,2023,$ as a result

of additional information, the company determined that the equipnent had a total useful life of seven years with a $$5,520$

residual value.

Durlng $2023,$ Sandhill changed from the double$-$declining$-$balance method tor 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 degreciation on both bases, The bulding had

or iginally cost $$1\mathrm{.}10$ million when purchased at the beginning of $2021$ and has a residual value of $$110\mathrm{.}000.$ It is depreciated

over $20$ years. The original estimates of useful life and residual value are stil accurate.

Sandhill purchased a machine on July $1,2020,$ at a cost of $$160,000.$ The machine has a residual value of $$16,000$ and a useful

life of eight years. Sandhill's bookeeper recorded straight$-$line depreciation during each year but failed to consider the

reskdual value.

Prior to $2023,$ development costs were expensed immediately because they were immaterial. Due to an increase in

develooment 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 igedic conditions for capitalization of development

phase costs. Amounts expensed in $2020\mathrm{.}2021,$ and $2022$ were $$400,$ $$700,$ and $$800,$ respectively. During $2023,$ $$4\mathrm{.}200$ was

spent and the amount was debited to Deferred Development Costs $\{$an asset account.
