In this presentation we will discuss the lastin first out inventory system on a periodic basis rather than a perpetual basis. As we go through this process, we want to always be comparing those to one, the LIFO or lastin first out system to other systems such as first in first out and average, as well as comparing the perpetual system to the periodic system. We’re going to go through this by looking at a problem the problem going into a worksheet such as this, I do recommend learning this worksheet. This worksheet should look repetitive if you seen the first in first out presentation as well as presentations for the perpetual system.
