Audit Evidence-What is It?
Evidence gathered in the course of an audit that
supports the auditor’s opinion and
Slide 5- 4
Why Audit Evidence?
A professional requirement by auditing
standard 2310.
 “Auditor should identify, sufficient,
reliable, relevant and useful information
to provide factual basis for audit
Slide 5- 5
Types of Evidence
Physical evidence
 Third-party representations
 Documentary evidence
 Computations
 Data Interrelationships
 Client representations
 Accounting records
Slide 5- 6
Types of Evidence
Physical Evidence
Evidence that can actually be seen by
» This type of evidence is generally effective
for supporting testing existence and
condition of the asset. Example –inspection
of a fixed asset.
Slide 5- 7
Types of Evidence
Third Party Representations
 Lawyers’ Letters
 Reports of Specialists
Slide 5- 8
Types of Evidence
Documentary Evidence
Four basic types (helps determine reliability):
Slide 5- 9
Created by outside parties and transmitted
directly to auditor
Created by outside parties and held by client
Created and held by client
Electronic documents
Types of Evidence
Computations are:
 Performed independently by auditor
 Used to verify mathematical accuracy of
client’s analyses and records
Slide 5- 10
Types of Evidence -Analytical
Data interrelationships (i.e., analytical
procedures) rely on plausible
relationships among financial and nonfinancial data.
Effective for testing “reasonableness” of
certain account balances
» Can be used as primary or corroborating evidence,
depending on the nature of account
Slide 5- 11
Types of Evidence
Oral and Written Client Representations
Responses to questions and inquiries to
clients during an audit constitute audit
» Oral representations are generally not
sufficient as primary evidence, but may
provide corroboration for other evidence.
» Written representations (representation
letter) are required, but should not be used
as a substitute for other audit procedures.
Slide 5- 12
The receipt of a written or oral response from an
independent third party.
Customers – confirm A/C receivable balances
Slide 5- 13
Suppliers – confirm A/C payable balances
Banks – confirm account/loan balances
Lawyers – confirm contingent liabilities
Types of Evidence
Accounting Records
Clients’ accounting records (e.g. ledgers
and journals) may provide worthwhile
evidence in themselves.
» Depends on the effectiveness of internal

Examination of documents that support
a recorded transaction or amount.
 The direction of testing must be from the
recorded item to the supporting
 Tests existence or occurrence.
 Also tests if transaction was properly
Slide 5- 16
Document Tracing
The primary test for unrecorded items
and therefore tests the completeness
 The direction of testing must be from the
supporting document to the recorded
 Also used to test if transactions were
recorded in rightful accounts.
Slide 5- 17
Auditor witnesses the physical activities of
the client.
 Useful in obtaining evidence that controls
which leave no documentary evidence of
application or existence are in operation.
 Differs from physical examination because
physical examination counts assets, while
observation focuses on client activities e.g.
inventory counting.
Slide 5- 18
Slide 5- 19
Reperformance involves rechecking a
sample of the computations to test
mathematical accuracy e.g.
reconciliations, interest computations
Inspection of Documents &
Slide 5- 20
Documents and other records
underlying a transaction or balance or
on which a control is applied are
inspected to obtain substantive evidence
or evidence of control. E.g. evidence of
proper authorisation.
Analytical Procedures
Auditors study relationships among
 Unusual fluctuations occur when
significant difference are not expected
but do exist or when significant
differences are expected but do not
 Required during the planning stage.
Slide 5- 21
Analytical Procedures
Analytical Procedures are useful in identifying
among other things:
 Differences that are not expected.
 The absence of differences when they are
 Potential errors, irregularities or illegal acts.
 Other unusual or non recurring transactions
or events.
Slide 5- 22
Analytical Procedures
If a change in one area would naturally lead
to a change in some other area, the
absence of the expected change should
lead to a further study in search of the
 Ex. If commissions paid to sales
representatives rise in one quarter, it would
be reasonable to expect a correspondence
increase in sales revenue.
Slide 5- 23
Relationship of marketing expenditure to
 Relationship of interest income to interest
earning assets.
 Relationship of interest expense to debt
 Such relationships are assumed to remain
the same unless some unknown condition
causes a change.
Slide 5- 24
Forms of Analytical
» Current period information with similar
information for prior periods.
» Current info with budgets or forecasts.
» Info for the audited unit with info for other
organisational units.
» Information for the audited unit with similar
information for the industry in which the
organisation operates.
Slide 5- 25
Analytical Procedures
» Study of relationships of financial info with
appropriate non financial info e.g. changes
in payroll expense compared to changes in
average number of employees.
» Study relationships among elements of
Slide 5- 26
Analytical Procedures
When analysis uncovers unexpected results,
auditors should undertake further study e.g.
making inquiries to management & applying
other audit procedures. The explanation may
lie in errors, irregularities or illegal acts.
 Further study should continue until the
auditor is satisfied that the results have been
sufficiently explained.
Slide 5- 27
Competence of Audit
To be competent evidence must be:
» Relevant
» Reliable
» Sufficient
» Useful
Slide 5- 28
Competence of
Evidential Matter
To be competent evidence must be:
Valid (Reliable)
Slide 5- 29
Must relate to the audit objective. E.g. purchase
order not relevant to prove that goods were actually
Independent sources have greater reliability than
those within the client organization.
Strong internal control increases reliability of
evidence created within the client organization.
Directly obtained evidence is more reliable than
evidence obtained second hand.
Reliability of Certain Types of
Audit Evidence
Slide 5- 30
Inventory Observation
Bank Statement
Purchase Invoice
Sales Invoice
Client Representations
Management Representation
Competence of Evidence
Evidence is sufficient if there is sufficient of it to
support the auditor’s findings. It must be convincing
enough for a prudent person to reach the same
decision/conclusion. E.g. interviewing the auditee is
not enough to provide sufficient evidence.
It must be factual and adequate to the testing
Verifying the physical condition is most persuasive
evidence as to condition of asset.
Slide 5- 31
Selection of Audit Procedures
The criteria for selection of the most
suitable technique can be based on the
» Will the technique meet the objectives of the
audit stage or phase?
» Has the auditor the skills to use the procedure?
» Is the material to be audited available and in a
condition to be used with the audit procedure.
Slide 5- 32
Selection of Audit Procedure
Will the procedure be cost effective?
E.g. will the time and effort to perform
the procedures far exceed the benefit of
using it?
 Will the conclusions reached after using
the procedure be valid?
Slide 5- 33
Compliance Audits
Compliance procedures provide evidence
that internal controls exist and that they are
being applied effectively and consistently.
 Procedures which can be used include:
» Enquiry & representation.
» Observation
» Inspection of supporting documents
» Re-performance of controls.
Slide 5- 34
Substantive Procedures
Substantive procedures provide direct
evidence as to the validity of a
transaction or balance in the records.
 An example is the checking of an entry
from an input voucher to a customer’s
Slide 5- 35
Substantive Procedures
Substantive Procedures include:
» Enquiry and representation.
» Analytical procedures.
» Detailed tests of transactions and balances
by: inspection of documents, physical
examination, external confirmation and
Slide 5- 36
Audit Documentation
Audit Standard: 2330-1
 Working Paper Files
 Typical Working Paper Format
 Storage of Working Papers
 Ownership of Working Papers
Slide 5- 37
Audit Documentation
Standard 2330-1:
» “Internal auditors must document relevant
information to support the conclusions and
engagement results”.
Slide 5- 38
Audit Documentation
Audit documentation is the principal record
of auditing procedures applied, evidence
obtained, and conclusions reached by the
 Audit Evidence is documented in Audit
working papers.
 Internal Audit Management Reviews these
Working papers to ensure quality is
Slide 5- 39
Working Papers -Objectives
Audit working papers achieve following
» Aid in the planning, performance, and
review of audit work.
» Provide the principal support for audit
report and conclusions.
» Facilitate third party/supervisory reviews.
Slide 5- 40
Working Paper-Objectives
Provide a basis for evaluating the internal
audit activity’s quality control program.
Document whether engagement
objectives were achieved.
 Support the accuracy and completeness
of the work performed.
Slide 5- 41
Key X-teristics of Work Papers
 Concise
 Accurate
 Organised
Slide 5- 42
» Each Work Paper should be completely self
standing and self explanatory. All questions
must be answered, all points raised by the
reviewer must be cleared and a logical, well
thought-out conclusion reached for each
audit segment.
Slide 5- 43
» High quality work papers include
statements and computations that are
accurate and technically correct.
Slide 5- 44
» Work papers should have a logical system
of numbering and a reader –friendly layout
so a technically competent person
unfamiliar with the project could understand
the purpose, procedures performed, and
Slide 5- 45
Relevance & Conciseness:
» Audit work papers and items included on
each work paper should be relevant to
meeting the applicable audit objective.
» Work papers must be confined to those that
serve a useful purpose.
Slide 5- 46
Work Paper Elements
Work papers should include the following
key elements:
» Name of audit area
» Source: The name and title of the individual
providing the documentation should be
recorded to facilitate future follow-up questions
or audits.
» Scope: The nature, timing, and extent of
procedures performed should be included on
each work paper for completeness.
Slide 5- 47
Elements of W/Papers
Reference: A logical work paper number
cross referenced to audit program steps
and issues should be included.
 Sign off: The preparer’s signature
provides evidence of completion and
accountability, which is an essential
piece of third party quality review.
