SCOPE
AU-C 300 provides guidance on planning a recurring audit of financial statements. Initial audit engagement planning is also addressed. Guidance for planning audits of group financial statements can be found in AU-C 600. (AU-C 300.01)
OBJECTIVE OF AU-C SECTION 300
The objective of the auditor is to plan the audit so that it will be performed in an effective manner.
(AU-C Section 300.04)
REQUIREMENTS
Preliminary Engagement Activities
It’s important for the engagement partner and other key members of the engagement team to be involved in planning the audit. (AU-C 300.05) The auditor should perform the following activities at the beginning of the current audit engagement:
Perform procedures regarding the continuance of the client relationship and the specific audit engagement. (AU-C 220)
Evaluate the auditor’s compliance with ethical requirements, including independence. (AU-C 220)
Establish the terms of the engagement. (AU-C 210)
(AU-C 300.06)
The purpose of performing these preliminary engagement activities is to consider any events or circumstances that either may adversely affect the auditor’s ability to plan and perform the audit or may pose an unacceptable level of risk to the auditor.
The Overall Audit Strategy
The auditor should establish and document the overall audit strategy for the audit. (AU-C 300.07)
The overall audit strategy involves the determination of:
The characteristics of the audit that define its scope
The reporting objectives of the engagement related to the timing of the audit and the required communications
Important factors that determine the focus of the audit team’s efforts
Factors to be considered from preliminary work or previous engagements
Nature, timing, and resources needed
(AU-C 300.08)
The audit strategy helps the auditor determine the resources necessary to perform the engagement.
Communications with Those Charged with Governance and Management
As required by AU-C 260, the auditor must discuss elements of planning and the scope with those charged with governance and the entity’s management. (AU-C 300.A13)
The Audit Plan
The audit plan is a more detailed, tactical plan that addresses the various audit matters identified in the audit strategy. The auditor must develop and document an audit plan for every audit.
The audit plan should include a description of:
The nature, timing, and extent of planned risk assessment procedures (AU-C 315)
The nature, timing, and extent of planned further audit procedures at the relevant assertion level for each material class of transactions, account balance, and disclosure (AU-C 330)
Other audit procedures to be carried out to comply with GAAS
(AU-C 300.09)
Developing an audit strategy and an audit plan is intended to be an iterative process. As information becomes available over the course of the audit, the auditor should reconsider the audit strategy and audit plan to determine whether they remain relevant. (AU-C 300.10) All changes to audit strategy and plan should be documented.
Establishing an audit strategy varies according to the size of the entity and the complexity of the audit. In audits of small entities, a very small audit team may conduct the entire audit. With a smaller team, coordination and communication between team members are easier. Consequently, establishing the overall audit strategy need not be a complex or time-consuming exercise.
As part of audit planning, the auditor plans the direction and supervision of engagement team members and plans for the review of their work. (AU-C 300.11)
NOTE: It is critical that the auditors do not simply use the prior-year audit plan. The auditors must perform inquiry and other procedures to determine what has changed and how those changes affect the audit plan. So, too, auditors should look with a skeptical eye at procedures performed in the past and determine whether they are necessary or could be eliminated or replaced with more effective procedures.
Determining the Extent of Involvement of Professionals Possessing Specialized Skills
The auditor should consider whether specialized skills are needed in performing the audit. (AU-C 300.12) For example, the auditor may need to involve the use of an information technology (IT) specialist to:
Determine the effect of IT on the audit
Understand the IT controls
Design and perform tests of IT controls or substantive procedures
In determining whether an IT professional is needed, the auditor should consider factors such as the following:
The complexity of the entity’s systems and IT controls and the manner in which they are used in conducting the entity’s business
The significance of changes made to existing systems, or the implementation of new systems
The extent to which data are shared among systems
The extent of the entity’s participation in electronic commerce
The entity’s use of emerging technologies
The significance of audit evidence that is available only in electronic form
(AU-C 300.A18)
Additional Considerations in Initial Audit Engagements
Before starting an initial audit, the auditor should:
Perform procedures regarding the acceptance of the client relationship and the specific audit engagement (see AU-C 220).
Communicate with the previous auditor, where there has been a change of auditors (see Section 210).
(AU-C 300.13)
When developing the overall audit strategy and audit plan, the auditor should consider:
Arrangements to be made with the previous auditor—for example, to review the previous auditor’s audit documentation.
Any major issues (including the application of accounting principles or of auditing and reporting standards) discussed with management in connection with the initial selection as auditors, the communication of these matters to those charged with governance, and how these matters affect the overall audit strategy and audit plan.
The planned audit procedures to obtain sufficient appropriate audit evidence regarding opening balances.
Other procedures required by the firm’s system of quality control for initial audit engagements (for example, the firm’s system of quality control may require the involvement of another partner or senior individual to review the overall audit strategy prior to commencing significant audit procedures or to review reports
