XYZ uses a periodic inventory system for its main operations (i.e., relates to item a above). The company has been using FIFO method. Upper management is contemplating a change in the method used to report the cost of goods sold. Please help the management to choose the method (either FIFO or DVLIFO) that maximizes earnings to shareholders. A physical inventory count indicated 40,000 units on hand at the end of 2019.

For price index of a year, you can take the most recent per unit price of the year divided by the base year per unit purchase price. Please make sure that you show your calculation of COGS and ending inventory under both FIFO and DVLIFO and explain the reason(s) for the method chosen.
