Given:
April 2, 2017 - paid $3,721,000 for 1,525,000 tons of ore deposit
installed machine costing $213,500. 7 year life. No salvage value. will be abandoned when ore deposit is completely mined.
May 1, 2017 - mining begins. 166,200 tons of ore mined and sold.
At the end of the year, depletion of the ore deposit and depreciation of the machinery must be recorded.
3,721,000 / 1,525,000 = 2.44 depletion rate per ton
2.44 * 166,200 = 405,528
entry on Dec. 31: Debit Credit
Depletion expense - Mineral deposit 405,528
Accumulated depletion - Mineral deposit 405,528
Depreciation of machine is not computed based on straight line method. It is computed based on the ratio of the ore deposit mined and sold to the total ore deposits.
(166,200 / 1,525,000) * 213,500 = 23,268
entry on Dec. 31 Debit Credit
Depreciation expense - Machinery 23,268
Accumulated depreciation - Machinery 23,268
