Final answer:
Accounting principles used in preparing financial statements should also be applied to segment information to ensure consistency and comparability across the financial statements, in line with IFRS and GAAP guidelines.
Step-by-step explanation:
True, the accounting principles used in preparing the financial statements (FS) should indeed be applied consistently in the presentation of segment information. This is to ensure that the information is comparable and consistent across all parts of the financial statements, providing a clear and accurate portrayal of a company's financial performance and condition. In particular, according to the International Financial Reporting Standards (IFRS) 8, Operating Segments, and the Generally Accepted Accounting Principles (GAAP), segment reporting should follow the same accounting policies as those that are applied in the preparation of the rest of the financial statements.
