Answer:
Under the retrospective approach to accounting for changes in accounting principles,
a journal is made to adjust the firm's Retained earnings balance to reflect the cumulative effect of the accounting principle change.
Step-by-step explanation:
A change in an accounting principle refers to a change in the accounting method. An example is using a different depreciation method (straight-line instead of double-declining method) or switching between Weighted-Average to LIFO inventory valuation method. Where there is a change in accounting principle, the change is applied retrospectively to the earliest period when financial statements are presented. The purpose is to ensure that the comparative financial statements reflect the new application of the accounting principle just as the current financial statements do. However, this cannot be done if it were impractical.
