Tell me about a time when an unexplained balance flows into the financial statements. What did you do?

I first confirmed the facts and contained the immediate impact. Next, I reviewed the trial balance, account movement, and reconciliation support and coordinated the action to investigate unusual balances, mapping, and period movements before reporting. After verifying the result, I summarized the root cause, preventive control, owner, and follow-up plan so the issue would not recur.
