AU Section 325

Communications About Control Deficiencies in an Audit of Financial Statements

• (1 - 9)

AU section 325 is superseded as follows:

• In an integrated audit of financial statements and internal control over financial reporting, by paragraphs 78-84 of PCAOB Auditing Standard No. 5, An Audit of Internal Control Over Financial Reporting That Is Integrated with An Audit of Financial Statements.
• In an audit of financial statements only, by the following paragraphs.

1. In an audit of financial statements, the auditor may identify deficiencies in the company's internal control over financial reporting. A control deficiency exists when the design or operation of a control does not allow management or employees, in the normal course of performing their assigned functions, to prevent or detect misstatements on a timely basis.

• A deficiency in design exists when (a) a control necessary to meet the control objective is missing or (b) an existing control is not properly designed so that, even if the control operates as designed, the control objective would not be met.
• A deficiency in operation exists when a properly designed control does not operate as designed or when the person performing the control does not possess the necessary authority or qualifications to perform the control effectively.

2. A significant deficiency is a deficiency, or a combination of deficiencies, in internal control over financial reporting, that is less severe than a material weakness yet important enough to merit attention by those responsible for oversight of the company's financial reporting.

3. 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.

Note: There is a reasonable possibility of an event when the likelihood of the event is either "reasonably possible" or "probable," as those terms are used in paragraph 3 of Financial Accounting Standards Board Statement No. 5, Accounting for Contingencies.

Note: In evaluating whether a deficiency exists and whether deficiencies, either individually or in combination with other deficiencies, are material weaknesses, the auditor should follow the direction in paragraphs 62-70 of PCAOB Auditing Standard No. 5, An Audit of Internal Control Over Financial Reporting That Is Integrated with An Audit of Financial Statements.

4. The auditor must communicate in writing to management and the audit committee all significant deficiencies and material weaknesses identified during the audit. The written communication should be made prior to the issuance of the auditor's report on the financial statements. The auditor's communication should distinguish clearly between those matters considered significant deficiencies and those considered material weaknesses, as defined in paragraphs 2 and 3.

Note: If no such committee exists with respect to the company, all references to the audit committee in this standard apply to the entire board of directors of the company. ^{fn 1} The auditor should be aware that companies whose securities are not listed on a national securities exchange or an automated inter-dealer quotation system of a national securities association (such as the New York Stock Exchange, American Stock Exchange, or NASDAQ) may not be required to have independent directors for their audit committees. In this case, the auditor should not consider the lack of independent directors or an audit committee at these companies indicative, by themselves, of a control deficiency. Likewise, the independence requirements of Securities Exchange Act Rule 10A-3 ^{fn 2} are not applicable to the listing of non-equity securities of a consolidated or at least 50 percent beneficially owned subsidiary of a listed issuer that is subject to the requirements of Securities Exchange Act Rule 10A-3(c)(2). ^{fn 3} Therefore, the auditor should interpret references to the audit committee in this standard, as applied to a subsidiary registrant, as being consistent with the provisions of Securities Exchange Act Rule 10A-3(c)(2). ^{fn 4} Furthermore, for subsidiary registrants, communications required by this standard to be directed to the audit committee should be made to the same committee or equivalent body that pre-approves the retention of the auditor by or on behalf of the subsidiary registrant pursuant to Rule 2-01(c)(7) of Regulation S-X ^{fn 5} (which might be, for example, the audit committee of the subsidiary registrant, the full board of the subsidiary registrant, or the audit committee of the subsidiary registrant's parent). In all cases, the auditor should interpret the terms "board of directors" and "audit committee" in this standard as being consistent with provisions for the use of those terms as defined in relevant SEC rules.

5. If oversight of the company's external financial reporting and internal control over financial reporting by the company's audit committee is ineffective, that circumstance should be regarded as an indicator that a material weakness in internal control over financial reporting exists. Although there is not an explicit requirement to evaluate the effectiveness of the audit committee's oversight in an audit of only the financial statements, if the auditor becomes aware that the oversight of the company's external financial reporting and internal control over financial reporting by the company's audit committee is ineffective, the auditor must communicate that information in writing to the board of directors.

6. These written communications should include:

a. The definitions of significant deficiencies and material weaknesses and should clearly distinguish to which category the deficiencies being communicated relate.

b. A statement that the objective of the audit was to report on the financial statements and not to provide assurance on internal control.

c. A statement that the communication is intended solely for the information and use of the board of directors, audit committee, management, and others within the organization. When there are requirements established by governmental authorities to furnish such written communications, specific reference to such regulatory authorities may be made.

7. The auditor might identify matters in addition to those required to be communicated by this standard. Such matters include control deficiencies identified by the auditor that are neither significant deficiencies nor material weaknesses and matters the company may request the auditor to be alert to that go beyond those contemplated by this standard. The auditor may report such matters to management, the audit committee, or others, as appropriate.

8. The auditor should not report in writing that no significant deficiencies were discovered during an audit of financial statements because of the potential that the limited degree of assurance associated with such a report will be misunderstood.

9. When timely communication is important, the auditor should communicate the preceding matters during the course of the audit rather than at the end of the engagement. The decision about whether to issue an interim communication should be determined based on the relative significance of the matters noted and the urgency of corrective follow-up action required. In an audit of financial statements only, auditing interpretation 1 to AU sec. 325, "Reporting on the Existence of Material Weaknesses," continues to apply except that the term "reportable condition" means "significant deficiency," as defined in paragraph 2 of this standard.
