Answer:
The correct answer is letter "C": The change should be reported retroactively.
Explanation:
Changes in Accounting Principles happen when a company switches between various generally accepted accounting principles or adjusts the process by which a rule is applied. Those changes can take place in accounting mechanisms for Generally Accepted Accounting Principles (GAAP) or International Financial Reporting Standards (IFRS). Â
When the changes happen, companies must apply it retrospectively to all previous accounting periods, as if the norm would have been always there.
