Final answer:
Consolidated financial statements on the date of acquisition of a subsidiary report the subsidiary's assets and liabilities at their historical cost.
Step-by-step explanation:
When preparing consolidated financial statements on the date of acquisition of a subsidiary, the correct statement is option b.
Option a is incorrect because only the subsidiary's revenues and expenses from the date of acquisition to the end of the reporting period are included.
Option c is incorrect because if a parent company owns less than 100% of a subsidiary, it must still consolidate 100% of the subsidiary's assets and liabilities.
Option d is incorrect because goodwill is only recorded if the parent company has paid more than the fair value of the subsidiary as a whole, not just the net assets.
Option e is incorrect because the parent company does not report an investment in the subsidiary separately on its balance sheet. Instead, the subsidiary's assets and liabilities are consolidated into the parent company's balance sheet.
