The best example of a change in accounting policy is the inventory valuationInventory Valuation Inventory Valuation Methods refers to the methodology (LIFO, FIFO, or a weighted average) used to value the company's inventories, which has an impact on the cost of goods sold as well as ending inventory, and thus has a financial impact on the company's bottom-line numbers and cash flow more. The company is using First in, First Out (FIFO) inventory(FIFO) InventoryUnder the FIFO method of accounting inventory valuation, the goods that are purchased first are the first to be removed from the inventory account.
