Part III. Inventory Problem (6 points) DFW Company uses the LIFO inventory costing method. DFW has been in business for ten years. At the end of December 2016, DFW's CEO has the option of purchasing 2,000 new units at a price of S30 per unit. She is asking your advice to decide whether DFW should purchase the inventory on 12/31/2016 or delay the purchase until 1/1/2017 (the price of the inventory on 12/31/2016 is assumed to be the same as that on 1/1/2017). DFW's income for 2016 is going to be much higher than market's expectations. As a result, the CEO's objective is to decrease income so that investors will not form extremely high performance expectations for 2017. DFW's current records reveal the following: Beginning Inventory (1/1/2016) Purchases during 2016 Quantity 2,000 13,000 Quantity 15,000 Cost per unit S12 S25 Price per unit S45 Sales during 2016 Required: Given the CEO's objective, when should she purchase the inventory? 12/31/2016 or 1/1/2017 or the timing is irrelevant?
