Overview of PCAOB's requirements for auditor attestation of control disclosures
(Source: KPMG report)
Auditing Standard No. 2' of the Public Company Accounting Oversight Board (PCAOB) has the following key requirements:

• The design of controls-relevant assertions related to all significant accounts and disclosures in the financial statements
• Information about how significant transactions are initiated, authorized, supported, processed, and reported
• Enough information about the flow of transactions to identify where material misstatements due to error or fraud could occur
• Controls designed to prevent or detect fraud, including who performs the controls and the regulated segregation of duties
• Controls over the period-end financial reporting process
• Controls over safeguarding of assets
• The results of management's testing and evaluation

Internal controls
Under Sarbanes-Oxley, two separate certification sections came into effect - one civil and the other criminal. See 15 U.S.C. § 7241 (Section 302) (civil provision); 18 U.S.C. § 1350 (Section 906) (criminal provision).

Section 302 of the Act mandates a set of internal procedures designed to ensure accurate financial disclosure. The signing officers must certify that they are "responsible for establishing and maintaining internal controls" and "have designed such internal controls to ensure that material information relating to the company and its consolidated subsidiaries is made known to such officers by others within those entities, particularly during the period in which the periodic reports are being prepared." 15 U.S.C. § 7241(a)(4). The officers must "have evaluated the effectiveness of the company's internal controls as of a date within 90 days prior to the report" and "have presented in the report their conclusions about the effectiveness of their internal controls based on their evaluation as of that date." Id..

Moreover, under Section 404 of the Act, management is required to produce an "internal control report" as part of each annual Exchange Act report. See 15 U.S.C. § 7262. The report must affirm "the responsibility of management for establishing and maintaining an adequate internal control structure and procedures for financial reporting." 15 U.S.C. § 7262)a). The report must also "contain an assessment, as of the end of the most recent fiscal year of the Company, of the effectiveness of the internal control structure and procedures of the issuer for financial reporting." Id. To do this, managers are generally adopting an internal control framework such as that described in COSO.

Under both Section 302 and Section 404, Congress directed the SEC to promulgate regulations enforcing these provisions. (See Final Rule: Management's Report on Internal Control Over Financial Reporting and Certification of Disclosure in Exchange Act Periodic Reports, Release No. 33-8238 (June 5,2003), available at http://www.sec.gov/rules/final/33-8238.htm.)

In addition, outside auditors for companies must, for the first time, attest to managers' internal control assessment, pursuant to SEC rules, which currently require only large public companies comply with this part of SOX. This presents new challenges to businesses, specifically, documentation of control procedures related to information technology ("IT"). Public Company Accounting Oversight Board (PCAOB) has issued guidelines on how auditors should provide their attestations.

Information technology and SOX 404
The PCAOB suggests considering the Committee of Sponsoring Organizations of the Treadway Commission (COSO) framework in management/auditor assessment of controls. Auditors have also looked to the IT Governance Institute's "COBIT: Control Objectives of Information and Related Technology" for more appropriate standards of measure. This framework focuses on information technology (IT) processes while keeping in mind the big picture of COSO's "control activities" and "information and communication". However, these certain aspects of COBIT are outside the boundaries of Sarbanes-Oxley regulation.
