Pina Colada Corp., which began operations in January 2017, follows IFRS and is subject to a 30% income tax rate. In 2020, the following events took place: 1. 2. 3. The company switched from the zero-proht method to the percentage-of-completion method of accounting for its long- term construction projects. This change was a result of experience with the project and improved ability to estimate the costs to completion and therefore the percentage complete. Due to a change in maintenance policy, the estimated useful life of Pina Colada's fleet of trucks was lengthened. It was discovered that a machine with an original cost of $224.000, residual value of $30,400, and useful life of 4 years was expensed in error on January 23, 2019, when it was acquired. This situation was discovered after preparing the 2020 adjusting entries but before calculating income tax expense and closing the accounts. Pina Colada uses straight-line depreciation and takes a full year of depreciation in the year of acquisition. The asset's cost had been appropriately added to the capital cost allowance (CCA) class in 2019 before the CCA was calculated and claimed. As a result of an inventory study early in 2020 after the accounts for 2019 had been closed, management decided that the weighted average cost formula would provide a more relevant presentation in the financial statements than does the FIFO cost formula. In making the change to weighted average cost, Pina Colada determined the following: 4. 4. As a result of an inventory study early in 2020 after the accounts for 2019 had been closed, management decided that the weighted average cost formula would provide a more relevant presentation in the financial statements than does the FIFO cost formula. In making the change to weighted average cost, Pina Colada determined the following: Date Inventory-FIFO Cost $87.000 Inventory-Weighted Average Cost $72,200 Dec 31, 2019 Dec 31, 2018 135,000 107,200 Dec. 31. 2017 187,000 142.200 Analyze each of the four 2020 events described above.
