Usually, the auditor is able to satisfy himself or herself regarding the reasonableness of management's estimate of the effects of future events by considering various types of evidential matter, including the historical experience of the entity. If the auditor concludes that management's estimate is unreasonable (see section 312, Audit Risk and Materiality, and section 342, Auditing Accounting Estimates) and that its effect is to cause the financial statements to be materially misstated, he or she should express a qualified or an adverse opinion.
