Question 1 On January 1, 2020 ABC Ltd., a publicly-traded oil extraction company, completed construction of a new drilling rig. The total cost to construct the rig was $8,500,000. By Canadian law, the rig must be removed and the land it is on must be cleaned up at the end of 20 years. The rig will be depreciated using the straight-line method and the estimated residual value of the rig at the end of 20 years is $0. The total cost to remove the rig and clean up the land in 20 years is expected to be $880,000. By ABC's estimate, 60% of this cost can be attributed to the removal of the rig itself, while the remaining 40% can be attributed to further damage to the land expected from the production process. ABC has calculated the present value of the increase in the asset retirement obligation related to production to be $6,111 in 2020 and $6,478 in 2021. ABC applies a discount rate of 6%. Instructions: a. Prepare the journal entries to record the acquisition of the oil rig and the asset retirement obligation for the rig on January 1, 2020. b.
