Explanation: A contingency factor is anything you can't predict accurately or forecast in the future. In order to cover currency fluctuations when services are done in local currency, contingency cost of 10-20% over basic cost estimate is advisable.
U.S. Generally Accepted Accounting Principles (GAAP) does not allow property, plant, and equipment to be written up or revalued. If the fair value of PP&E falls below the book value and the amount is material then a company must write down the asset to fair value.
Since under US GAAP, once PPE is written, it can not be reversed. as Company B is indicated to have reversed the write down while company A did not. It therefore means that Company A only is reporting under US GAAP.
