1. Describe the LIFO double-extension method. Using the following information, compute the index at December 31, 2012, applying the double-extension method to a LIFO pool consisting of 25,500 units of product A and 10,350 units of product B. The base-year cost of product A is $10.20 and of product B is $37.00. The price at December 31, 2012, for product A is $21.00 and for product B is $45.60. (Round to two decimal places.)
2. As compared with the FIFO method of costing inventories, does the LIFO method result in a larger or smaller net income in a period of rising prices? What is the comparative effect on net income in a period of falling prices?
3. What is the dollar-value method of LIFO inventory valuation? What advantage does the dollar-value method have over the specific goods approach of LIFO inventory valuation? Why will the traditional LIFO inventory costing method and the dollar-value LIFO inventory costing method produce different inventory valuations if the composition of the inventory base changes?
