The notes to the financial statements will also described how the manufacturer's inventory is valued. For example, the notes will disclose whether FIFO lower of cost or market, LIFO, weighted average, or other cost flow methods were used. If LIFO is used, then the excess of current cost over LIFO cost is also disclosed.
