  1. Inventory write-down reversals are not allowed under US GAAP

  2. Revaluation of long-lived assets is allowed only under IFRS. US GAAP only permits the historical cost model.

  3. Investment in financial assets under IFRS, impairment losses on available-for-sale equity securities cannot be reversed but can be on debt securities.

  4. Investment is associates, both US GAAP and IFRS prohibit the reversal of impairment losses even if the fair value is later increased.
