In what way does IAS 16 (Property, Plant, and Equipment) differ from U.S. GAAP concerning fixed asset measurement subsequent to initial recognition?

IAS 16 allows for upward revaluation of the asset based on fair value.

IAS 16 does not allow accumulated depreciation to be shown on the balance sheet.

IAS 16 requires that fixed assets be carried at fair value less accumulated impairment losses.

IAS 16 allows both upward and downward revaluation of fixed assets, whereas U.S. GAAP only allows upward revaluation.
