I have a few accounting questions I need help with....all true or false...?
1. The cash or cash equivalent price of items classified as property, plant, and equipment best measures the value of the asset on the date of acquisition. 2. When land has been purchased for the purpose of constructing a new building, all costs incurred in connection with preparing the land for excavation are considered building costs. 3. The purpose of imputed interest is to approximate interest rate of deferred purchase contract when one is not expressly stated. 4. The recommended accounting treatment for donated property, plant, and equipment represents a departure from cost principle. 5. By definition, any addition to a building is capitalized because a new asset has been created. 6. If an asset still can be used even though it is fully depreciated, it may be kept on the books at historical cost less depreciation, or the asset may be carried at scrap value. 7. Equipment purchased through deferred payment contracts should be accounted for at present value.
