Analysis of Inventory
Inventory management is a double-edged sword

costs (e.g., investment, storage, insurance,
obsolescence, and damage).
2. Low Inventory Levels – may lead to stockouts and
lost sales.

that inventory would increase (or occasionally
decrease) if the company had instead been using FIFO.
This amount is referred to as the LIFO reserve.

Inventory errors affect the computation of cost of

An error in ending inventory of the current period
will have a reverse effect on net income of the
next accounting period.
Over the two years, the total net income is correct
because the errors offset each other.
The ending inventory depends entirely on the
