There are a number of accounting methods that can be used for asset and liability valuation. In some cases, fair value is appropriate; with others, historical cost is required. Please discuss the different methods as they apply to investments, current liabilities and contingencies. Conclude your discussion with which valuation method you find the most appropriate for the accounts listed above. You may use either GAAP and/or IFRS standards for your discussion. Use at least two outside references for your initial posting. Accounting articles are preferred.
