  1. Overview of PCAOB Auditing Standard No. 5 An Audit of Internal Control Over Financial Reporting that is Integrated with an Audit of Financial Statements

  2. PCAOB’s New Guidance for Audits of Internal Control • Issued May 24, 2007 to supersede PCAOB Auditing Standard No. 2 • Responds to concerns about perceived inefficiencies in initial years of AS2 implementation, without reducing audit effectiveness • Retains most of the core concepts of AS2 described in Chapter 10 of Auditing & Assurance Services: An Integrated Approach • Effective for audits of fiscal years ending on or after November 15, 2007

  3. Key Changes in AS5 • The new standard • Emphasizes a top-down risk based approach • Places greater reliance on entity-level controls • Focuses on understanding and testing controls related to risks for significant accounts and disclosures • Allows for greater ability to rely on work of others • Changes definition of material weakness and significant deficiency • Simplifies the auditor’s opinion by eliminating opinion on management’s assessment of internal control

  4. Top Down Risk Based Approach • Emphasizes auditor focus on controls related to risks that might lead to material misstatements: • Begins at the financial statement level with consideration of risks affecting overall financial statements • Leads to identifying and understanding entity-level controls management has implemented to address overall financial statement risks • Encourages auditor to consider entity-level controls before assessing controls related to specific objectives • Notes that fraud risk is an area of higher overall risk requiring auditor to focus on antifraud programs and controls • Recognizes that size and complexity of entity and its processes affect the nature of risks and need for related controls

  5. Entity-Level Controls • Focus on entity-level controls helps direct auditor to controls related to high risk areas • Entity-level controls often include those related to control environment, risk assessment, and monitoring components of internal control • Leads to audit efficiencies by reducing tests at transaction, account, or disclosure levels because • Some entity-level controls indirectly affect performance of other controls • Other entity-level controls directly monitor operating effectiveness of other controls

  6. Significant Accounts and Disclosures • AS5 requires auditor to identify controls relevant to significant accounts and disclosures • An account or disclosure is significant if there is • “a reasonable possibility that the account or disclosure could contain a material misstatement that, individually or when aggregated with others, has a material effect on the financial statements.” • Represents a change from AS2, which required the auditor to understand controls for each “material class of transactions” within a single process • Likely will reduce the extent of walkthroughs the auditor must perform • Emphasizes controls where risks of material misstatements are highest

  7. Using Work of Others • Allows auditor to use the work of others to obtain evidence about operating effectiveness of internal controls • Includes work performed by company personnel or others working under the direction of management or audit committee • Tests performed by management to provide Section 404 assertion • Requires assessment of • Competence and Objectivity of individuals performing work • Relative risks associated with controls tested

  8. Evaluating Deficiencies • AS5 revises definitions of material weakness and significant deficiency • Material weakness is • “a deficiency, or 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.” • Significant deficiency is • “a deficiency, or combination of deficiencies, in internal control over financial reporting that is less severe than a material weakness, yet important to merit the attention by those responsible for oversight of the company’s financial reporting.”

  9. Auditor’s Opinion • AS2 required two auditor opinions on: • Whether management’s assessment of internal controls was fairly stated • Whether internal controls over financial reporting operated effectively • AS5 eliminates the first opinion • Auditor’s opinion must only address whether the company maintained, in all material respects, effective internal control over financial reporting as of the end of the fiscal year • Change affects auditor’s report wording in the introductory and opinion paragraphs of the combined report shown in Figure 3-3
