An organizations audit charier PRIMARILY:

The audit charter is the foundational document for the internal audit function. Its primary purpose is to formally define the internal audit activity's purpose, authority, and responsibility. It is approved by the highest level of governance (e.g., the board of directors or audit committee) and senior management. This charter grants the audit function the authority to access all necessary records, personnel, and physical properties; defines the scope of its activities; and establishes its position and independence within the organization's structure. This formal delegation of authority is the charter's most critical function, enabling auditors to perform their duties effectively and without obstruction.

B. defines the auditors' code of conduct. The code of conduct is typically a separate professional standard (e.g., from ISACA or the IIA) that auditors must follow, not a document created primarily for the charter. C. formally records the annual and quarterly audit plans. Audit plans are separate, dynamic operational documents that detail specific audits; the charter is a high-level, more static document that grants the authority to create and execute these plans. D. documents the audit process and reporting standards. Detailed audit processes and standards are documented in an audit manual or procedural guides, not in the high-level, governing audit charter.

1. ISACA

CISA Review Manual

27th Edition. Chapter 1

Section 1.3.1

"Internal Audit Charter." The manual states

"The internal audit charter is a high-level document... It should state management’s responsibility and objectives for

and delegation of authority to

the internal audit function." This directly confirms the charter's primary role is to establish authority.

2. The Institute of Internal Auditors (IIA)

International Standards for the Professional Practice of Internal Auditing (Standards). Standard 1000: "Purpose

Authority

and Responsibility." The standard mandates

"The purpose

authority

and responsibility of the internal audit activity must be formally defined in an internal audit charter... The internal audit charter... authorizes access to records

personnel

and physical properties relevant to the performance of engagements; and defines the scope of internal audit activities."

which are critical for its effectiveness within the corporate governance structure.
