Final answer:
When consolidating a subsidiary under the equity method, only depreciable net assets that have excess fair value over book value must be amortized over their useful lives.
Step-by-step explanation:
When consolidating a subsidiary under the equity method, the correct statement is D) only depreciable net assets that have excess fair value over book value must be amortized over their useful lives.
Under the equity method of accounting, the parent company recognizes its share of the subsidiary's net income as a single-line item on its own income statement. The subsidiary's assets and liabilities are not revalued to fair value, except in the case of depreciable net assets that have excess fair value over book value. These assets are amortized over their useful lives.
