CA 9.4 (Continued)
Seasonal variations in the rate of markup will nullify the ending inventory “representative mix”
assumption. Since the estimated cost ratio is based on total merchandise handled during the
period, the same rate of markup should prevail throughout the period. Because of seasonal
variations it may be necessary to use data for the last six months, quarter, or month to compute a
cost ratio that is appropriate for ending inventory.
Distortion of the ending inventory approximation under this method is often caused by an inadequate
system of inventory control. Adequate accounting controls are necessary for the accurate accumula-
tion of the data needed to arrive at a valid cost ratio. Physical controls are equally important
because, for interim purposes, this method is usually applied without taking a physical inventory.
(c) The advantages of using the retail method as compared to cost methods include the following:
1. Approximate inventory values can be determined without maintaining perpetual inventory records.
(d) The treatments to be accorded net markups and net markdowns must be considered in light of
their effects on the estimated cost ratio. If both net markups and net markdowns are used in
arriving at the cost ratio, ending inventory will be converted to an estimated average cost figure.
Excluding net markdowns will result in the inventory being stated at an estimate of the LCNRV.
