AICPA Exam CPA-Auditing Topic 2 Question 56 Discussion

Choice 'a' is correct. An auditor should obtain management's written assertion about the effectiveness of the entity's internal control.

Choice 'b' is incorrect. The accountant should disclaim (not qualify) an opinion on management's assertions that the cost of correcting weaknesses exceeds the benefits.

Choice 'c' is incorrect. The accountant has no responsibility to evaluate the effect of subsequent events. In fact, the report on an entity's internal control specifically states that projections of the internal control evaluation to future periods is inappropriate.

Choice 'd' is incorrect. The accountant does provide an opinion (and not a disclaimer) on the effective operation of internal control.
