I know, the words “material weakness” just seem so extreme. When I ask an engagement team about its evaluation of control deficiencies and whether there could be a material weakness, the team will almost always respond, “No, we really think it’s just a significant deficiency.” The thought process being, how could a little control deficiency that deals with an immaterial variance possibly rise to the level of a material weakness? Of course, I always follow up with “Tell me why.”
I suppose to start, we should define a material weakness. The PCAOB defines the term as follows:
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company's annual or interim financial statements will not be prevented or detected on a timely basis. 1
The key here is the term “reasonable possibility.” It does not mean that there is in fact a material misstatement, but rather that the internal controls over financial reporting would not sufficiently prevent or detect a material misstatement and thus, there could potentially be a material misstatement.
Time and again, through various pre- and post-issuance reviews as well as through my experience with audit consultations, I have seen engagement teams struggle to appropriately evaluate deficiencies in internal control. Often, teams will look at the control deficiency and point to the fact that the deficiency involves an immaterial variance. If only it were so simple to conclude as such. It’s like engineers building the leaning Tower of Pisa saying, “The ground hasn’t fully settled, but it’s only off by a couple degrees. It’s not that material.” No, a couple degrees may not be significant, but if it compromises the structure of the tower, well, then it’s material.
The guidance within the PCAOB is housed within AS 2201, An Audit of Internal Control Over Financial Reporting That is Integrated with An Audit of Financial Statements. Controls deficiencies can arise from testing the operating effectiveness of controls in an integrated audit as well as from the identification of audit misstatements during substantive testing. Thus, while AS 2201 is pertinent to integrated audits, it is equally applicable to non-integrated audits when engagement teams are evaluating the severity of control deficiencies. AS 2201 provides numerous factors to be considered when evaluating control deficiencies including some of the following:
To perform a thorough evaluation of a control deficiency, engagement teams should understand the nature of the deficiency (what went wrong?) and the root cause (why did it go wrong?). From there, the engagement team can make an appropriate determination of the potential account balance at risk and consider what controls would compensate for the known issue.
In addition, teams need to evaluate each deficiency in isolation as well as in aggregate. Aggregation could be grouped by account, location, or client entity; engagement teams should consider multiple levels of aggregation if they exist and/or are merited. AS 2201 specifically states that, “Multiple control deficiencies that affect the same financial statement account balance or disclosure increase the likelihood of misstatement and may, in combination, constitute a material weakness, even though such deficiencies may individually be less severe.” 2
In our work with audit firms, we often instruct teams to first consider each deficiency to be a potential material weakness, and then, after evaluating the various factors, reduce the severity of the deficiency from a material weakness to a significant deficiency or to a control deficiency. Essentially, start first with the presumption that it is a material weakness and then tell me why it’s not.
Regardless of the severity, engagement teams need to document the impact of the control deficiency on the substantive audit. If it’s just a control deficiency and there is a relevant compensating control, there may be no impact on the substantive audit. However, if it evolves into a significant deficiency and/or material weakness, there would likely be some sort of impact on the substantive audit if the engagement team planned on a control reliance approach.
While it’s easy to write all this, performing the evaluation itself is difficult. Teams often feel burdened to “make it go away” because a discussion with management and the audit committee around a material weakness is not easy. But that doesn’t change management or the auditor’s responsibility. Management is responsible for the design and implementation of internal controls over financial reporting. The auditor is simply there to evaluate the design and operating effectiveness and conclude based on the testing.
I encourage teams to take a step back and trust your gut. When I perform reviews, I’m not looking for material weaknesses, but when I find one, it’s generally pretty obvious to me (and to the team, honestly). All it takes is a couple questions and teams agree. So, trust your gut; if it smells like a material weakness, it probably is.
