The LIFO reserve, LIFO-to-FIFO conversion and LIFO liquidation

The LIFO reserve is the gap between FIFO and LIFO inventory; adding it back, and its change to cost of sales, lets an analyst put a US GAAP LIFO company on the same footing as a FIFO or IFRS peer.

In short

  • LIFO reserve = FIFO inventory − LIFO inventory. US GAAP LIFO companies disclose it in the notes.
  • FIFO inventory = LIFO inventory + LIFO reserve.
  • FIFO COGS = LIFO COGS − change in LIFO reserve. A rising reserve means FIFO cost of sales is lower.
  • FIFO-adjusted figures give higher inventory, current ratio and (with rising costs) profit and equity, and lower inventory turnover.
  • LIFO liquidation: selling more units than are bought dips into old, cheap layers, cutting cost of sales and inflating margins temporarily. US GAAP requires disclosure of material liquidation income.
