Performance Standards 2330 - Documenting Information
Internal auditors must document relevant information to support the conclusions and engagement results
Functions of working papers

1. Aid in the planning, performance, and review of engagements


2. Provide the principal support for engagement results


3. Document whether engagement objectives were achieved


4. Support the accuracy and completeness of the work performed


5. Provide a basis of the internal audit activity's quality assurance and improvement program


6. Facilitate third part reviews

What must working papers include, at a minimum
Identify the engagement and describe the contents or purpose of the working paper. Should be signed and dated by the internal auditor and contain an index or reference number
Primary objective of maintaining security over working papers
Prevent unauthorized changes or removal of information
Implementation Standards 2330.A1 - Control of Working Papers
The CAE must control access to engagement records. The CAE must obtain the approval of senior management and/or legal counsel prior to releasing such records to external parties, as appropriate
May working papers be shown to the client?
Yes, when engagement objectives will not be compromised, to encourage corrective action
Implementation Standard 2330.A2 - Working Paper Retention
The CAE must develop retention requirements for engagement records, regardless of the medium in which each record is stored. These retention requirements must be consistent with the organization's guidelines and any pertinent regulatory or other requirements
Common flowchart symbols
What are flowcharts
Graphical representations of the step-by-step progression of information through preparation, authorization, flow, storage, etc
What is process mapping
A simple form of flowcharting used to depict a client process
What are horizontal flowcharts (system flowcharts)
Depict areas of responsibility (departments of functions) arranged horizontally across the page in vertical columns. Accordingly, activities, controls, and document flows that are the responsibility of a given department or function are shown in the same column.
What are vertical flowcharts (program flowcharts)
Present successive steps in a top-to-bottom format. Principal use is in the depiction of the specific actions carried out by a computer program
Data flow diagrams
Show how data flow to, from, and within an information system and the processes that manipulate the data. Can be used to depict lower-level details as well as higher-level processes.
Performance Standard 2310 - Identifying Information
Internal auditors must identify sufficient, reliable, relevant, and useful information to achieve the engagement's objectives
Sufficient information
Factual, adequate, and convincing so that a prudent, informed person would reach the same conclusions as the auditor. The difference in risk determines the quality and quantity of information
Reliable information
The best attainable information through the use of appropriate engagement techniques
When is information more reliable

1. Obtained from sources other than the engagement client


2. Corroborated by other information


3. Direct rather than indirect


4. An original document, not a copy

Relevant information
Supports engagement observations and recommendations and is consistent with the objectives for the engagement
Useful information
Helps the organization meet its goals
Pneumonic for four qualities of information

SRRU - Should Rick Record Uniformly


Forms of legal evidence

Direct Evidence



Circumstantial Evidence



Conclusive Evidence



Corroborative Evidence

Direct Evidence
Establishes a particular fact of conclusions without having to make any assumptions - i.e., testimony by a witness
Circumstantial Evidence
Establishes a fact or conclusion that can then lead by inference to another fact
Conclusive Evidence
Absolute proof, by itself
Corroborative Evidence
Serves to confirm a fact or conclusions that can be inferred from other evidence
Forms of audit evidence

Physical


Testimonial


Documentary

Physical Information
The auditor's direct observation and inspection of people, property, or activities, e.g., of the counting of inventory
Testimonial Information
Consists of written or spoken statements of client personnel and others in response to inquiries or interview questions
Documentary Information
Exists in some permanent form, such as checks, invoices, shipping records, receiving reports, and purchase orders
Analytical Information
Drawn from the consideration of the interrelationships among data or, in the case of internal control, the particular policies and procedures of which it is comprised
Internal Information
Originates and remains with the engagement client - i.e., payroll records
Reliability of internal information
Lack of involvement of external parties reduces the persuasiveness of information. Reliability is greater when it comes from sources that are independent of the client
Internal-External Information
Originates with the client but also is processed by an external process - i.e., cancelled checks are created by the client but circulate through the banking system. Bank acceptance of a check is some confirmation of its validity
Reliability of internal-external information
More reliable than purely internal information
External-Internal Information
Created by an external party but subsequently processed by the client - i.e., supplier invoices
Reliability of external-internal information
Greater validity than information initiated by the client, but its value is impaired because of the client's opportunity to alter or destroy it
External Information
Created by an independent party and transmitted directly to the internal auditor - i.e., receivables sent in response to the auditor's request
Reliability of external information
Ordinarily regarded as the most reliable because it has not been exposed to possible alteration or destruction by the client
Levels of Persuasiveness of Evidence

1. Auditor physical examination


2., Direct examination


3. Information from a third-party


4. Information from the client
