How often the asset is to be revaluated (posting variant)
Which values to revaluate, for example, whether to base the revaluation
on the asset's acquisition and production costs or on some other value
Which inflation index to use, for example, the general inflation index or a specific index
Which date to use the inflation index from
How to handle assets that were posted partway through a given period,
for example, to disregard them completely and only revaluate it in the
first full period (time base and exposure to inflation variant)
