Farleigh O. Tuvit is a new member of the controller's staff in the same company as you. Farleigh has just completed a report that urges the company to adopt the LIFO method for inventory accounting. The controller is con- cerned about the recommendation because the cost records are maintained on a FIFO basis. Indeed, the controller has not even heard of using LIFO for process cost accounting. Can you suggest how the controller might resolve the problem?
