Answer:
A negative translation adjustment must be reported.
Step-by-step explanation:
Under the current rate method, the company must report a negative translation adjustment on a reserve account in the consolidated balance. This reserve account is included in the consolidated balance sheet as unrealized gains/losses.
The marketable securities were purchased at 1,000,000 / 20 = $50,000 (US dollars). But now they are worth only 1,000,000 / 25 = $40,000 (US dollars).
The reserve account of the consolidated financial statements should show a negative foreign currency translation adjustment equal to $10,000 (US dollars).
