Dell Computer Company produces computers. The following data and descriptions are from the company's annual report (S in millions): February 3 January 28 2012 2011 Inventories $1,404 S1,301 Assume that Dell uses the periodic inventory system. Suppose a division of Dell had the data conceming the purchase and resale of computers (S are not in millions): Units Total Inventory (January 28, 2011) 100 S40,000 Purchase (February 20, 2011) 200 100,000 Sales, March 17, 2011 (at S900 per unit) 150 Purchase (June 25, 2011) 160 96,000 Sales, November 7, 2011 (at S1,000 per unit) 160 1. For these computers only, prepare a tabulation of the cost of goods sold section of the income statement for the yearended February 3, 2012. Support your computations. Show your tabulation for four different inventory methods: (a) FIFO, (b) LIFO, (c) average cost known as weighted-average for periodic inventory systems, and (d) specific identification. For requirement (d), assume that the purchase of February 20 was identified with the sale of March 17. Also assume that the sale of November 7 included the sale of half of the units in beginning inventory and the remainder from the purchase of June 25. 2. By how much would income taxes differ if Dell used (a) LIFO instead of FIFO for this inventory item, and (b) LIFO instead of weighted average? Assume a 40% tax rate
