42. Management may conclude that a previously reported material weakness no longer exists because it has been reduced to a significant deficiency. If management does not plan to correct the significant deficiency within a reasonable period of time, the auditor should evaluate whether the remaining significant deficiency could be indicative of a material weakness in internal control over financial reporting. Under paragraph 140 of Auditing Standard No. 2, a significant deficiency not corrected after some reasonable period of time is a strong indicator of a material weakness. Because the auditor is not required to provide an opinion under this voluntary engagement, the auditor could reasonably decline to provide an opinion under such circumstances.
