Both the management of Carla Vista Instrument Corporation, a small company that follows IFRS, and its independent auditors recently concluded that the company's results of operations will be reliable and more relevant in future years if Carla Vista changes its method of costing inventory from FIFO to weighted average cost. The following data are a five-year income summary using FIFO and a schedule of what the inventories might have been if they had been stated using the weighted average cost method. Prepare comparative statements for the five years that would be suitable for inclusion in the historical summary portion of Carla Vista's annual report, assuming that Carla Vista had changed its inventory costing method to weighted average cost in 2023. Indicate the effects on net income and earnings per share for the years involved. (Round earnings per share to 2 decimal places, e.g. 52.75. Round answers to 0 decimal places, e.g. 5,275.)
