Hi everybody, I am reading SS9 book 3 about inventory analysis. LOS 35c explained that the analyst select conversion of inventory from LIFO to FIFO using LIFO reserve, COGS from FIFO to LIFO and COGS from average cost to LIFO to adjust financial data more comparable. I just wonder if analysts meet companies using inventory costing method of average and FIFO. How can they make adjustment for more comparable number? The book doesn’t mention that. I know FIFO inventory and LIFO COGS reflect the best current value but some time we still meet firms using FIFO and average method of inventory and we have to make adjustment before computing financial ratios. Could anybody kindly make it clear for me? Thank you very much.
