Analysis Case 20-4
For changes not involving LIFO or changes from the LIFO method to another, the
event is accounted for as a normal change in accounting principle. In general, we
report voluntary changes in accounting principles retrospectively. This means
The advantage of retrospective application is to enhance comparability of the
statements from year to year. The recast statements appear as if the newly adopted
accounting method had been applied in all previous years.
Consistency and comparability suggest that accounting choices once made should
be consistently followed from year to year. So, any change requires that the new
report the change retrospectively. Because of this difficulty, a company changing to
LIFO usually does not report the change retrospectively. Instead, the base year
inventory for all future LIFO calculations is the beginning inventory in the year the
LIFO method is adopted. Then, the LIFO method is applied prospectively from that
point on. The disclosure note must include an explanation as to why retrospective
application was impracticable.
