Final answer:
The controller spends time and makes changes to the amounts reported by individual companies when preparing consolidated financial statements to ensure accurate representation of the entire entity. FASB and IASB have different approaches to consolidation, with IFRS allowing for more flexibility in accounting treatment.
Step-by-step explanation:
The reason why the controller spends a lot of time and makes changes to the amounts reported by individual companies when preparing consolidated financial statements is because the parent company and its subsidiaries may have different accounting policies and practices.
These differences need to be reconciled and adjusted to ensure that the financial statements accurately reflect the consolidated financial position and performance of the entire entity.
According to the Financial Accounting Standards Board (FASB), the consolidation process involves eliminating intercompany transactions and balances to avoid double-counting and ensuring that the financial statements are presented as if the parent and its subsidiaries are a single entity.
This requires careful analysis and adjustments to align the accounting practices of the different entities.
In contrast, the International Accounting Standards Board (IASB) approach, under International Financial Reporting Standards (IFRS), also focuses on producing consolidated financial statements of the parent and its subsidiaries.
However, IFRS allows more flexibility in the accounting treatment of certain transactions, which may result in differences in the consolidation process compared to FASB (GAAP).
