IT plays an ever increasing role in financial reporting. In particular the amount of automation. Internal controls over IT are essential. Consequently they are central to any evaluation of compliance with Sarbanes-Oxley and section 404.
Section 404 requires public companies to not only confirm that they have internal controls in relation to financial reporting. They have to be demonstrably effective.
IT has its own rules and good practice that act as guidance in setting internal controls. Financial reporting also has internal control guidance.
An important aspect of considering IT in relation to section 404, is that we only need to look at internal controls that touch upon financial reporting. Not all controls have an IT element nor, do all IT controls impact on reporting.
Reviewing IT controls is such huge subset of internal controls, received wisdom is that a sub-committee of the main Sarbanes-Oxley steering/evaluation committee should be set up.
We shall discuss in-depth, how to review IT related in upcoming articles. Three sources will be prominent in virtually all of them.
Internal controls and their evaluation for financial reporting, are extensively covered in the Internal Control - Integrated Framework published by the Committee of Sponsoring organisations of the Treadway Commission. (Referred to as the COSO framework.) This document is referred to in Sarbanes-Oxley as a source of guidance. Consequently it is the widely cited in evaluation.
The COSO framework identifies 5 elements that go to make up a company's internal controls.
The IT Governance Institute produce the industry standard on guidance for IT controls, Control Objectives for Information and related Technology. The scope of this framework covers the entire range of IT controls, far wider in fact than just those with financial implications.
A bridge between the two was needed to focus attention on the cross-over between the two frameworks. This has been provided by the Information Systems Audit and Control Association (ISACA). Their document, IT Control Objectives for Sarbanes-Oxley is required reading for any one evaluating this area of controls.
