Statement of Auditing Standard No. 94 The Effect of Information Technology on the Auditor’s Consideration of Internal Control in a Financial Statement Audit

SAS 94 The Effect of Information Technology on the Auditor’s Consideration of Internal Control in a Financial Statement Audit

This amendment to SAS 55 provides guidance to auditors relative to information technology. Prior to this amendment, the SAS did not contain any IT guidance. Although the SAS makes no reference to continuous auditing, several of the requirements of SAS 94 appear to be best satisfied by use of continuous auditing techniques.

SAS 94 says an organization’s IT use may effect and of the five internal control components as well as how businesses initiate, record, process and report transactions. The SAS offers auditors some direction by pointing out these key aspects of the systems and controls on which organizations rely.

The purpose of this paper is to suggest specific points of SAS 94 where continuous auditing techniques can be applied. The CPA would then be able to perform a more efficient audit and satisfy the requirements of SAS 94. Generally, the “specific risks” identified by SAS 94 are areas that many CPAs have little familiarity. Continuous auditing techniques could be linked to these specific risks thereby creating a benefit to the CPA for employing continuous auditing.

SAS 94 Guidance

Obtaining an understanding of internal control

A sufficient understanding is obtained by performing procedures to understand the design of controls relevant to an audit of financial statement and determining whether they have been placed in operation. In planning the audit, such knowledge should be used to:

← Identify types of potential misstatement.

← Consider factors that affect the risk of material misstatement.

← Design tests of controls, when applicable.

← Design substantive tests.

Definition of “Information Technology”

Information technology (IT) encompasses automated means of originating, processing, storing, and communicating information, and includes recording devices, communication systems, computer systems (including hardware and software components and data), and other electronic devices.

Five interrelated components

➢ Control environment

➢ Risk assessment

➢ Control activities

➢ Information and communication systems support

➢ Monitoring

Potential benefits

□ Consistently apply predefined business rules and perform complex calculations in processing large volumes of transactions and data.

□ Enhance the timeliness, availability, and accuracy of information.

□ Facilitate the additional analysis of information

□ Enhance the ability to monitor the performance of the entity’s activities and its policies and procedures.

□ Reduce the risk that controls will be circumvented.

Specific risks

o Reliance on systems or programs that are inaccurately processing data, processing inaccurate data, or both.

o Unauthorized access to data that may result in destruction of data or improper changes to data, including the recording of unauthorized or nonexistent transactions or inaccurate recording of transactions.

o Unauthorized changes to data in master files.

o Unauthorized changes to systems or programs.

o Failure to make necessary changes to systems or programs.

o Inappropriate manual intervention.

o Potential loss of data.
