Wallace Lumber uses LIFO and had the following note in its last financial statement: "Wallace Lumber showed a LIFO reserve of $90,000 in 2003 and $86,000 in 2004." Wallace's marginal tax rate is 31%.
If Wallace's year-end LIFO inventory balance was $400,000, their inventory based on FIFO would be:
INVF = INVL + LIFO reserve
=$400,000 + $86,000
= $486,000
If Wallace's LIFO COGS were $70,000, their FIFO COGS would be:
COGSF = COGSL - (LIFO reserveE - LIFO reserveB)
= $70,000 - ($86,000 - $90,000)
= $74,000
