Which statement is false?

The GPLA model does not consider the specific price changes in the fixed assets, inventories and other physical assets.

Under the CCA Model, realized gains and losses are not reported in CCA income statements.

A weakness of the CCA method is that for certain types of fixed assets, determining current costs can be highly subjective.

The CCA Model tends to understate reported earnings relative to the historical$-$cost model in equity oriented companies.

All of the above statements are true.
