Final answer:
Since AAA & Associates did not retest the controls after the remediation of material weaknesses in LinktheEarth Corporation's internal control, they should issue a disclaimer of opinion on the internal control over financial reporting at year-end.
Step-by-step explanation:
When AAA & Associates completed the audit of LinktheEarth Corporation's internal control over financial reporting and found material weaknesses, even though management remediated these weaknesses, the auditors did not retest the controls. In this situation, AAA & Associates should issue a disclaimer of opinion because they have not had sufficient time to perform the necessary retesting to verify the effectiveness of the remediation. A disclaimer of opinion is appropriate when the auditors cannot obtain enough appropriate audit evidence on which to base the opinion, which includes situations where controls have been changed but not retested.
