Answer:
a. Determine the cost of the copper mine.
b. Prepare the journal entries to record the acquisition costs.
Date X, 2021, acquisition of copper mine
Dr Copper mine 2,104,430
Cr Cash 1,780,000
Cr Asset retirement liability 324,430
July 1, 2021, acquisition of mining equipment
Dr Equipment 150,000
Cr Cash 150,000
Explanation:
estimated restoration costs = ($330,000 x .25) + ($430,000 x .4) + ($630,000 x .35) = $475,000
now we must adjust the restoration cost and determine its present value = $475,000 x 0.68301 (present value factor, 10%, 4 periods) = $324,430
total cost of copper mine = purchase cost + preparation costs + restoration costs = $1,150,000 + $630,000 + $324,430 = $2,104,430
