First Principles Thinking: PPE disclosure requirements
C is correct. Under IFRS, for each class of property, plant, and equipment, a company must disclose items such as the measurement basis, depreciation method, useful life or depreciation rate, gross carrying amount, accumulated depreciation, and a reconciliation of carrying amount. Measurement basis and depreciation method are therefore required disclosures.
The first distractor is wrong because IFRS does not require the exact purchase date of every asset as part of the listed disclosure requirements.
The remaining distractor is wrong because individual machine market values are not the required class-level PPE disclosure.
