ASSURANCE AND RELATED SERVICES
PHILIPPINE FRAMEWORK FOR ASSURANCE ENGAGEMENTS
OBJECTIVE AND GENERAL PRINCIPLES GOVERNING AN AUDIT OF FINANCIAL STATEMENTS (PSA
200 [Amended as a result of PSA 700 (Revised)])
The Authority Attaching to Philippine Standards Issued by the AASC
STANDARDS
APPLICATION
1. Philippine Standards on Auditing (PSAs)
 Audit of historical financial information
2. Philippine Standards on Review
 Review of historical financial information
Engagements (PSREs)
3. Philippine Standards on Assurance
 Assurance engagements dealing with
Engagements (PSAEs)
subject matters other than historical
financial information
4. Philippine Standards on Related Services
 Compilation engagements
(PSRSs)
 Engagements to apply agreed-upon
procedures to information
 Other related services engagements as
specified by the AASC
1. PSAs, PSREs, PSAEs and PSRSs are collectively referred to as the AASC’s Engagement Standards.
2. Philippine standards on Quality Control (PSQC) are to be applied for all services falling under the
AASC’s engagement standards.
3. Philippine Standards are applicable to engagements in the Public sector.
The Authority Attaching to Practice Statements Issued by the AASC
1. Philippine Practice Statements are issued to:
 Provide interpretive guidance and practical assistance o professional accountants in
implementing Philippine Standards; and
 Promote good practice
2. Professional accountants should be aware of and consider Practice Statements applicable to the
engagement.
3. A professional accountant who does not consider and apply the guidance included in a relevant
Practice Statements should be prepared to explain how the basic principles and essential
procedures in the AASC’s Engagement Standard(s) addressed by the Practice Statement have
been complied with.
PHILIPPINE FRAMEWORK FOR ASSURANCE ENGAGEMENTS
1. The Framework does not itself establish standards or provide procedural requirements for the
performance of assurance engagements.
2. In addition to the Framework and PSAs, PSREs and PSAEs, practitioners who perform assurance
engagements are governed by:
 The Philippine Code of Ethics for Professional Accountants; and
 Philippine Standards on Quality Control (PSQCs)
ASSURANCE ENGAGEMENTS
1. “Assurance engagement” means an agreement in which a particular expresses a conclusion
designed to enhance the degree of confidence of the intended users other than the responsible
party about the outcome of the evaluation or measurement of a subject matter against criteria.
2. “Subject matter information” refers to the outcome of the evaluation or measurement of a
subject matter.
3. In some assurance engagements, the evaluation or measurement of the subject I performed by
the responsible party, and the subject matter information is in the form of an assertion by the
responsible party that is made available to intended users (assertion-based engagements).
4. In other assurance engagements, the practitioner either directly performs the evaluation or
measurement of the subject matter, or obtains a representation from the responsible party that
2
has performed the evaluation or measurement that is not available to the intended users in the
assurance report (direct reporting engagements)
TWO TYPES OF ASSURANCE ENGAGEMENT
1. Reasonable assurance engagement – the objective is a reduction in assurance engagement risk
to an acceptably low level in the circumstances of the engagement as the basis for a positive
form of expression of the practitioner’s conclusion.
2. Limited assurance engagement – the objective is a reduction in assurance engagement risk to a
level that is acceptable in the circumstances of the engagement, but where the risk is greater
than for a reasonable assurance engagement, as a basis for a negative form of expression of the
practitioner’s conclusion.
SCOPE OF THE FRAMEWORK
The following are non-assurance engagements and therefore are not covered by the Framework:
1. Engagements covered by the PSRSs such as agreed-upon procedures engagements and
compilations of financial or other information.
2. The preparation of tax returns where no conclusion conveying assurance is expressed.
3. Consulting (or advisory) engagements, such as management and tax consulting.
ELEMENTS OF AN ASSUARANCE ENGAGEMENT
1. A three-party relationship involving:
 A practitioner;
 A responsible party; and
 Intended users.
2. An appropriate subject matter;
3. Suitable criteria;
4. Sufficient appropriate evidence; and
5. A written assurance report in the form appropriate to a reasonable assurance engagement or a
limited assurance engagement.
OBJECTIVE AND GENERAL PRINCIPLES GOVERNING AN AUDIT OF FINANCIAL STATEMENTS
1. The OBJECTIVE of an audit of financial statements is to enable the auditor to express an opinion
whether the financial statements are prepared, in all material respects, in accordance with an
applicable financial reporting framework.
2. The auditor should comply with relevant ethical requirements relating to audit engagements.
3. The auditor should conduct the audit in accordance with PSAs.
4. “Scope of an audit” refers to the audit procedures that, in the auditor’s judgment and based on
PSAs, are deemed appropriate in the circumstances to achieve the objective of the audit.
5. The auditor should plan and perform an audit with an attitude of PROFESSIONAL SKEPTICISM
recognizing that circumstances may exist that cause the financial statements to be materially
misstated.
6. In forming the audit opinion, the auditor obtains sufficient appropriate evidence to be able to
draw conclusions on which to base that opinion.
7. The auditor’s opinion enhances the credibility of financial statements by providing a high, but
not absolute, level of assurance.
8. Absolute assurance in auditing is not attainable as a result of such factors as:
 The need for judgment;
 The use of testing;
 The inherent limitations of any accounting and internal control systems; and
 The fact that most of the evidence available to the auditor is persuasive, rather than
conclusive, in nature.
9. While the auditor is responsible for forming and expressing an opinion on the financial
statements, the responsibility for the preparation and presentation of the financial statements
in accordance with the applicable financial reporting framework is that of the entity’s
MANAGEMENT, with oversight from those charged with governance.
3
ENGAGEMENTS TO REVIEW FINANCIAL STATEMENTS
1. The objective of a review of financial statements is to enable a practitioner to state whether, on
the basis of procedures which do not provide all the evidence that would be require in an audit,
anything has come to the practitioner’s attention that causes the practitioner to believe that the
financial statements are not prepared, in all material respects, in accordance with an identified
financial reporting framework (negative assurance)
2. A review comprises INQUIRY and ANALYTICAL PROCEDURES which are designed to review the
reliability of an assertion that is the responsibility of one party for use by another party.
3. A review does not ordinarily involve an assessment of accounting and internal control systems,
tests of records and of responses to inquiries by obtaining corroborating evidence through
inspection, observation, confirmation and computation, which are procedures ordinarily
performed during an audit.
4. The level of assurance provided in a review report is less that that given in an audit report.
ENGAGEMENTS TO PERFORM AGREED-UPON PROCEDURES REGARDING FINANCIAL INFORMATION
1. In an engagement to perform agreed-upon procedures, an auditor is engaged to carry out those
procedures of an audit nature to which the auditor and the entity and any appropriate third
parties have agreed and to report on FACTUAL FINDINGS.
2. The recipients of the report must form their own conclusion from the report of the auditor.
3. The report is restricted to those parties that have agreed to the procedures to be performed
since others, unaware of the reasons for the procedures, may misinterpret the results.
ENGAGEMENTS TO COMPILE FINANCIAL INFORMATION
1. In a compilation engagement, the accountant is engaged to use accounting expertise as
opposed to auditing expertise to collect, classify, and summarized financial information.
2. It ordinarily entails reducing detailed data to manageable and understandable form without a
requirement to test the assertions underlying that information.
3. The procedures performed are not designed and do not enable the accountant to express any
assurance on the financial information.
4. Users of compiled financial information derived some benefit as a result of the accountant’s
involvement because the service has been performed with due professional skill and care.

competence and time to perform the audit engagement in accordance with
professional standards and regulatory and legal requirements, and to enable an
auditor’s report that is appropriate in the circumstances to be issued.
e. Take responsibility for the direction, supervision and performance of the audit
engagement in compliance with professional standards and regulatory and legal
requirements, and for the auditor’s report that is issued to be appropriate n he
circumstances.
f. Be satisfied that sufficient appropriate audit evidence has been obtained to support
the conclusions reached and for the auditor’s report to be issued.
PSA 210 [AMENDED BY THE PSA 700 (REVISED)]
1. The purpose of this standard is to establish standards and provide guidelines on:
a. Agreeing the terms of the engagement with the client; and
b. The auditor’s response to a request by a client to change the terms of an
engagement to one that provides a lower level of assurance.
2. Audit Engagement Letters
 It is in the interest of both client and auditor that the auditor sends an engagement
letter, preferably before the commencement of the engagement, to help in avoiding
misunderstandings with respect to the engagement.
5
 Principal Contents
An engagement letter would generally include reference to:
 The objective of the audit of financial statements.
 Management’s responsibility for the financial statements.
 The financial reporting framework adopted by management in
preparing the financial statements.
 The scope of the audit, including reference to applicable
legislation, regulations or pronouncements of professional
bodies to which the auditor adheres.
 The form of any reports or other communication of results of
the engagement.
 The fact that because of the test nature and other inherent
limitations of an audit, together with the inherent limitations of
any accounting and internal controls system, there is an
unavoidable risk that even some material misstatement may
remain undiscovered.
 Unrestricted access to whatever records, documentation and
other information requested in connection with the audit.
3. Acceptance of a Change in Engagement
1. An auditor who, before the completion of the engagement, is requested to change
the engagement tone which provides a lower level of assurance, should consider the
appropriateness of doing so.
2. A request from the client for the auditor to change the engagement may result
from:
a. A change in circumstances affecting the need for the service;
b. A misunderstanding as to the nature of an audit or related service originally
requested; or
c. A restriction on the scope of the engagement, whether imposed by
management or caused by circumstances.
(NOTE: A or B would ordinarily be a reasonable basis for requesting a
change in the engagement)
3. A change would not be considered reasonable if it appeared that the change relates
to information that is incorrect, incomplete or otherwise unsatisfactory.
4. Before agreeing to change an audit engagement to a related service, an auditor
would also consider any legal or contractual implications of the change.
5. If the auditor concludes that there is reasonable justification to change the
engagement and if the audit work performed complies with the PSAs applicable to
the change engagement, the report issued would be that appropriate for the revised
terms of the engagement.
6. In order to avoid confusing the reader, the report would not include reference to:
a. The original engagement; or
b. Any procedures that may have been performed by the original engagement,
except where the engagement is changed to undertake agreed-upon
procedures.
7. Where the terms of the engagement are changed, the auditor and the client should
agree in the new terms.
8. The auditor should not agree to a change of engagement where there is no
reasonable justification for doing so.
9. If the auditor is unable to agree to a change of engagement and is not permitted to
continue the original engagement, the auditor should withdraw and consider
whether there is any obligation, contractual or otherwise, to report to other parties,
such as the board of directors or shareholders, the circumstances necessitating the
withdrawal.

THE RISKS OF MATERIAL MISTATEMENT
PSA 300 (Rev.)
PLANNING AN AUDIT OF FINANCIAL STATEMENTS
1.
Planning an audit involves:
 establishing the overall audit strategy for the engagement and
 developing an audit plan,
 in order to reduce audit risk to an acceptably low level.
Preliminary Engagement Activities
2.
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.
 Evaluate compliance with ethical requirements, including independence.
 Establish an understanding of the terms of the engagement.
Planning Activities
3.
The auditor should establish the overall audit strategy for the audit. The overall audit strategy sets
the scope, timing and direction of the audit, and guides the development of the more detailed
audit plan
4.
The establishment of the overall audit strategy involves:
a.) Determining the characteristics of the engagement that define its scope;
b.) Ascertaining the reporting objectives of the engagement to plan the timing of the audit and the
nature of the communication required; and
c.) Considering the important factors that will determine the focus of the engagement team’s
efforts.
5.
The auditor should develop an audit plan for the audit in order to reduce audit risk to an
acceptably low level.
The audit plan is more detailed than the overall audit strategy and includes the nature, timing and
extent of audit procedures to be performed by engagement team members in order to obtain
sufficient appropriate audit evidence to reduce audit risk to an acceptably low level.
6.
7.
The audit plan includes:
 A description of the nature, timing and extent of planned risk assessment procedures sufficient
to assess the risks of material misstatement as determined under PSA 315, “Understanding the
Entity and its Environment and Assessing the Risks of Material Misstatement.”;
 A description of the nature, timing and extent of planned further audit procedures at the
assertion level for each material class of transactions, account balance, and disclosure, as
determined under PSA 330, “The Auditor’s Procedures in Response to Assessed Risks,”; and
 Such other procedures required to be carried out for the engagement in order to comply with
PSAs
Changes to Planning Decisions during the Course of the Audit
The overall audit strategy and the audit plan should be updated and changed as necessary during the
course of the audit.
7
Direction, Supervision and Review
1.
The auditor should plan the nature, timing and extent of direction and supervision of engagement
team members and review their work.
2.
The nature, timing and extent of the direction and supervision of engagement team members and
review of their work vary depending on many factors, including:




3.
The size and complexity of the entity;
The area of audit;
The risks of material misstatement; and
The capabilities and competence of personnel performing the audit work.
The auditor plans the nature, timing and extent of direction and supervision of engagement team
members based on the assessed risk of material misstatement.
Documentation
The auditor should document the overall audit strategy and the audit plan, including any significant
changes made during the audit engagement.
Communications with Those Charged with Governance and Management
1.
The auditor may discuss elements of planning with those charged with governance and the entity’s
management.
2.
Discussions with those charged with governance ordinarily include the overall audit strategy and
timing of the audit, including any limitations thereon, or any additional requirements.
3.
When discussion of matters included in the overall audit strategy or audit plan occur, care is
required in order not to compromise the effectiveness of the audit.
Additional Considerations in Initial Audit Engagements
The auditor should perform the following activities prior to starting an initial audit:
1.
Perform procedures regarding the acceptance of the client relationship and the specific audit
engagement.
2.
Communicate with the previous auditor, where there has been a change of auditors, in compliance
with relevant ethical requirements.
PSA 315
UNDERSTANDING THE ENTITY AND ITS ENVIRONMENT AND ASSESSING THE RISKS OF MATERIAL
MISSTATEMENT
1.
The auditor should obtain an understanding of the entity and its environment, including its internal
control, sufficient to identify and assess the risks of material misstatement of the financial
statements whether due to fraud or error, and sufficient to design and perform further audit
procedures.
2.
The auditor should perform the following risk assessment procedures to obtain an understanding
of the entity and its environment, including its internal control:
a.) Industry, regulatory, and other external factors, including the applicable financial reporting
framework.
b.) Nature of the entity, including the entity’s selection and application of accounting policies.
c.) Objectives and strategies and the related business risks that may result in a material
misstatement of the financial statements.
d.) Measurement and review of the entity’s financial performance.
e.) Internal control.
8
INTERNAL CONTROL
1.
Internal control is the process designed and effected by those charged with governance,
management, and other personnel to provide reasonable assurance about the achievement of the
entity’s objectives with regard to:
 Reliability of financial reporting;
 Effectiveness and efficiency of operations; and
 Compliance with applicable laws and regulations.
2.
The auditor uses the understanding of internal control to:
 Identify types of potential misstatements;
 Consider factors that affect the risks of material misstatement; and
 Design the nature, timing and extent of further audit procedures.
3.
Internal control consists of the following components:
1.) The control environment.
2.) The entity’s risk assessment process.
3.) The information system, including the related business processes, relevant to financial
reporting, and communication.
4.) Control activities.
5.) Monitoring of controls.
The control environment includes the governance and management functions and the attitudes,
awareness, and actions of those charged with governance and management concerning the entity’s
internal control and its importance in the entity.
Elements of control environment:
a) Communication of enforcement of integrity and ethical values.
b) Commitment to competence.
c) Participation by those charged with governance.
d) Management’s philosophy and operating style.
e) Organizational structure.
f) Assignments of authority and responsibility.
g) Human resource policies and practices.
The auditor should obtain an understanding of the entity’s risk assessment process, i.e., the entity’
process for identifying business risks relevant to financial reporting objectives and deciding about
actions to address those risks, and the results thereof.
The auditor should obtain an understanding of the information system, including the related
business processes, relevant to financial reporting, including the following areas:

The classes of transactions in the entity’s operations that is significant to the financial
statements.

The procedures, within both IT and manual systems, by which those transactions are
initiated, recorded, processed and reported in the financial statements.

The related accounting records, whether electronic or manual, supporting information, and
specific accounts in the financial statements, in respect of initiating, recording, processing
and reporting transactions.

How the information system captures events and conditions, other than classes of
transactions that are significant to the financial statements.

The financial reporting process used to prepare the entity’s financial statements, including
significant accounting estimates and disclosures.
9
Control activities are the policies and procedures to help ensure that management directives are
carried out. Examples of control activities include those relating to the following:
 Authorization
 Performance reviews.
 Information processing.
 Physical controls.
 Segregation of duties.
Monitoring of controls involves assessing the design and operation of controls on a timely basis
and taking the necessary corrective actions modified for changes in conditions.
4.
Obtaining an understanding of internal control involves:
a) Evaluating the design of a control; and
b) Determining whether it has been implemented.
ASSESSING THE RISKS OF MAERIAL MISSTATEMENT
1.
The auditor should identify and assess the risks of material misstatement at the financial
statements level, and at the assertion level for classes of transactions, account balances, and
disclosures.
2.
The auditor:
 Identifies risks throughout the process of obtaining an understanding of the entity and its
environment, including relevant controls that relate to the risks, and by considering the
classes of transactions, account balances, and disclosures in the financial statements;
 Relates the identified risks to what can go wrong at the assertion level;
 Considers whether the risks are of a magnitude that could result in a material
misstatement of the financial statements; and
 Considers the likelihood that the risks could result in a material misstatement of the
financial statements.

THE AUDITOR’S PROCEDURES IN REPONSE TO ASSESSED RISKS
Overall responses
1. The auditor should determine overall responses to address the risks of material misstatement at
the financial statement level. Such responses may include:
 Emphasizing to the audit team the need to maintain professional skepticism n
gathering and evaluating audit evidence
 Assigning more experienced staff or those with special skills or using experts
 Providing more supervision
 Incorporating additional elements of unpredictability in the selection of further
audit procedures to be performed
 Making general changes to the nature, timing or extent of audit procedures
Audit Procedures Responsive to Risks of Material Misstatement at the Assertion Level
1. In designing further audit procedures, the auditor considers the following:
 The significance of the risk
 The likelihood that the material misstatement will occur
 The characteristics of the class transactions, account balance, or disclosure
involved.
 The nature of the specific controls used by the entity and in particular whether
they are manual or automated
 Whether the auditor expects to obtain audit evidence to determine if the
entity’s controls are effective n preventing, or detecting and correcting, material
misstatements
2. Considering the nature, timing and extent of further audit procedures
The nature of further audit procedures refers to their:
a. Purpose- tests of controls or substantive procedures
b. Type - inspection, observation, inquiry, confirmation, recalculation,
reperformance, or analytical procedures.
Timing refers to when audit procedures are performed or the period or date to which the audit
evidence applies.
Extent includes the quantity of a specific audit procedure to be performed.
TESTS OF CONTROLS
1. The auditor is required to perform tests of controls when:
a. The auditor’s risk assessment includes an expectation of the operating effectiveness
of controls; or
b. When the substantive procedures alone do not provide sufficient appropriate audit
evidence at the assertion level
2. Tests of the operating effectiveness of controls are performed only on those controls that
the auditor has determined are suitably designed to prevent, or detect and correct, a
material misstatement in an assertion
3. Testing the operating effectiveness of controls includes obtaining evidence about:
a. How controls were applied at relevant times during the period under audit;
b. The consistency with which they were applied; and
c. By whom or by what means they were applied.
SUBSTANTIVE PROCEDURES
1. Substantive test procedures are performed in order to detect material misstatements at the
assertion level, and include:
 Tests of details of classes of transactions, account balances, and disclosures; and
 Substantive analytical procedures
11
2. The auditor’s substantive procedures should include the following audit procedures related to
the financial statement closing process:
 Agreeing or reconciling the financial statements with accounting records; and
 Examining material journal entries and other adjustments made during the
course of preparing the financial statements
3. The auditor should perform audit procedures to evaluate whether the overall presentation of
the financial statements, including the related disclosures, are in accordance with the applicable
financial reporting framework.
Evaluating the sufficiency and appropriateness of audit evidence obtained
1. Based on the audit procedures performed and the audit evidence obtained, the auditor should
evaluate whether the assessments of the risks of material misstatement at the assertion level
remain appropriate.
2. The auditor should conclude whether the assessments of the risks of material misstatement in
the financial statements.
3. If the auditor has not obtained sufficient appropriate audit evidence as to a material financial
statement assertion, the auditor should attempt to obtain further audit evidence. If the auditor
is unable to obtain further audit evidence, the auditor should express a qualified opinion or a
disclaimer of opinion.
Documentation
1. The auditor should document:
 The overall responses to address the assessed risks of material misstatement at
the financial statement level and the nature, timing, and extent of the further
audit procedures;
 The linkage of those procedures with the assessed risks at the assertion level;
and
 The results of the audit procedures
2. If the auditor plans to use audit evidence about the operating effectiveness of controls obtained
in prior audits, the auditor should document the conclusions reached with regard to relying on
vcfsuch controls that were tested in a prior audit.
3. The auditor’s documentation should demonstrate that the financial statements agree or
reconcile with the underlying accounting records.

ANALYTICAL PROCEDURES
RELATED PARTIES
CONSIDERING THE WORK OF INTERNAL AUDIT
USING THE WORK OF AN EXPERT
PSA 320
AUDIT MATERIALITY
1. Materiality should be considered by the auditor when:
 Determining the nature, timing and extent of audit procedures; and
 Evaluating the effect of misstatements
2. There is an inverse relationship between materiality and the level of audit risk
3. In evaluating whether the financial statements are prepared, in all material respects, in
accordance with an applicable financial reporting framework, the auditor should assess whether
the aggregate of uncorrected misstatements that have been identified during the audit is
material.
4. If the auditor concludes that the aggregate of uncorrected misstatements may be material, the
auditor needs to consider:
 Reducing audit risk by extending audit procedures; or
 requesting management to adjust the financial statements for the
misstatements identified
5. If management refuses to adjust the financial statements and the results of extended audit
procedures do not enable the auditor to conclude that the aggregate of uncorrected
misstatements is not material, the auditor should consider the appropriate modification to the
auditor’s report.
6. If the auditor has identified a material misstatement resulting from error, the auditor should
communicate the misstatements to the appropriate level of management on a timely basis, and
consider the need to report it to those charged with governance.
PSA 520
ANALYTICAL PROCEDURES
1. “Analytical procedures” means the analysis of significant ratios and trends including the
resulting investigation of fluctuations and relationships that are inconsistent with other relevant
information or which deviate from predicted amounts.
2. Analytical procedures also include consideration of comparisons of the entity’s financial
statements:
a. Comparable information for prior periods
b. Anticipated results of the entity, such as budgets or forecasts, or expectations of the
auditor, such as an estimation of depreciation
c. Similar industry information
3. Analytical procedures also include consideration of relationships:
a. Among elements of financial information that would be expected to conform to a
predictable patter based on the entity’s experience, such as gross margin
percentages.
b. Between financial information and relevant no-financial information, such as payroll
costs to numbers and employees
4. The auditor should apply analytical procedures at the planning stage to assist in understanding
the business and in identifying areas of potential risk. Analytical procedures in planning the use
both financial and non-financial information.
5. The auditor should apply analytical procedures at or near the end of the audit when performing
an overall conclusion as to whether the financial statements as a whole are consistent with the
auditor’s knowledge of the business.
6. The application of analytical procedures is based on the expectation that relationships among
data exist and continue in the absence of known conditions to the contrary. The presence of
these relationships provides audit evidence as to the completeness, accuracy and validity of the
data produced by the accounting system
7. The extent of reliance that the auditor places on the results of analytical procedures depends on
the following factors:
13
a. Materiality of the items involved
b. Other audit procedures directed toward the same audit objectives
c. Accuracy with which the expected results of analytical procedures can be predicted.
8. When analytical procedures identify significant fluctuations or relationships that are
inconsistent with other relevant information or that deviate from predicted amounts, the
auditor should investigate and obtain adequate explanations and appropriate corroborative
evidence.
9. The investigation of unusual fluctuations and relationships ordinarily begins with inquiries of
management, followed by:
a. Corroboration of management responses; and
b. Consideration of the need to apply other audit procedures based on the results of
such inquiries, if management is unable to provide an explanation or if the
explanation is not considered adequate.
PSA 550
RELATED PARTIES
1. Management is responsible for the identification and disclosure of related parties and
transactions with such parties.
2. The auditor should perform audit procedures designed to obtain sufficient appropriate audit
evidence regarding the identification and disclosure by management of related parties and the
effect of related party transactions that are material to the financial statements. However, an
audit cannot be expected to detect all related party transactions.
3. The auditor needs to have a sufficient understanding of the entity and its environment to enable
identification of the events, transactions and practices that may result in a risk of material
misstatement regarding related parties and transactions with such parties.
4. When obtaining an understanding of the entity’s internal control, the auditor should consider
the adequacy of control activities over the authorization and recording of related party
transactions.
5. In examining the identified related party transactions, the auditor should obtain sufficient
appropriate audit evidence as to whether these transactions have been properly recorded and
disclosed.
6. The auditor should obtain a written representation from management concerning:
a. The completeness of information provided regarding the identification of related
parties; and
b. The adequacy of related party disclosures in the financial statements
7. The auditor is unable to obtain sufficient appropriate audit evidence concerning related parties
and transactions with such parties or concludes that their disclosure in the financial statements
is not adequate; the auditor should modify the audit report appropriately.
PSA 610
CONSIDERING THE WORK OF INTERNAL AUDIT
1. The external auditor should obtain a sufficient understanding of internal audit activities to
identify and assess the risks of material misstatement of the financial statements and to design
and perform further audit procedures.
2. The external auditor should perform an assessment of the internal audit function when internal
auditing is relevant to the external auditor’s risk assessment.
3. When obtaining an understanding and performing a preliminary assessment of the internal
audit function, the important criteria are:
a. Organizational status
b. Scope of the function
c. Technical competence
d. Due professional care
4. When planning to use the work of internal auditing, the external auditor will need to consider
internal auditing’s tentative plan for the period and discuss it as early a stage as possible.
5. Where the work of internal auditing is to be a factor in determining the nature, timing and
extent of the external auditor’s procedures, it is desirable to agree in advance the timing of such
work, the extent of audit coverage, materiality levels and proposed methods of sample
selection, documentation of the work performed and review and reporting procedures.
6. A liaison with internal auditing is more effective when meetings are held at appropriate intervals
during the period.
14
7. When the external auditor intends to use specific work of internal auditing, the external auditor
should evaluate and perform audit procedures on that work to confirm its adequacy for the
external auditor’s purposes.
8. The evaluation of specific work of internal auditing involves consideration of the adequacy of
the scope of the work and related programs and whether the preliminary assessment of the
internal auditing remains appropriate.
9. The nature, timing and extent of audit procedures performed on the specific work of internal
auditing will depend on:
 The external auditor’s judgment as to the risk of material misstatement of the
area concerned;
 The assessment of internal auditing; and
 The evaluation of the specific work by internal auditing.
10. The external auditor would record conclusions regarding the specific internal auditing work that
has been evaluated and the audit procedures performed on the internal auditor’s work.
PSA 620
USING THE WORK OF AN EXPERT
1. “Expert’ means a person or firm possessing special skill, knowledge and experience in a
particular filed other than accounting and auditing.
2. An expert may be:
a. Contracted by the entity;
b. Contracted by the auditor;
c. Employed by the entity; or
d. Employed by the auditor.
3. When determining the need to use the work of an expert, the auditor would consider:
a. The materiality of the financial statement item being considered;
b. The risk of misstatement based on the nature and complexity of the matter being
considered; and
c. The quantity and quality of other audit evidence available
4. When planning t use the work of an expert, the auditor should evaluate the professional
competence and objectivity of the expert.
5. The risk that an expert’s objectivity will be impaired increases when the expert is:
a. Employed by the entity; or
b. Related in some other manner to the entity.
6. The auditor should obtain sufficient appropriate audit evidence that the scope of the expert’s
work is adequate for the purposes of the audit. Audit evidence may be obtained through a
review of the terms of reference which are often set out in written instructions from the entity
to the expert.
Such instructions to the expert may cover matters such as:
a. The objectives and scope of the expert’s work
b. A general outline as to the specific matters the auditor expects the expert’s report
to cover
c. The intended use by the auditor of the expert’s work, including the possible
communication to third parties of the expert’s identity and extent f involvement
d. The extent of the expert’s access to appropriate records and files
e. Clarification of the expert’s relationship with the entity, if any.
f. Confidentiality of the entity’s information
g. Information regarding the assumptions and methods intended to be used by the
expert and their consistency with those used in prior periods.
7. The auditor should evaluate the appropriateness of the expert’s work as audit evidence
regarding the financial statement assertion being considered. This will involve assessment of
whether the substance of the expert’s findings is properly reflected in the financial statements
or supports the financial statement assertions, and consideration of:
a. Source data used.
b. Assumptions and methods used and their consistency with prior periods
c. Results of the expert’s work in the light of the auditor’s overall knowledge of the
business and of the results of other audit procedures.
8. When considering whether the expert has used source data which is appropriate in the
circumstances, the auditor would consider the following procedures:
a. Making inquiries regarding any procedures undertaken by the expert to establish
whether the source data is sufficient, relevant and reliable.
b. Reviewing or testing the data used by the expert
15
9. If the results of the expert’s work do not provide sufficient audit evidence or if the results are
not consistent with other audit evidence, the auditor should resolve the matter. This may
involve:
a. Discussions with the entity and the expert
b. Applying additional audit procedures
c. Including possibly engaging another expert; or
d. Modifying the auditor’s report
10. When issuing an unmodified auditor’s report, the auditor should not refer to the work of an
expert. Such a reference might be misunderstood to be a qualification of the auditor’s opinion
or a division of responsibility, neither of which is intended.
11. If as a result of the work of an expert, the auditor decides to issue a modified auditor’s report, in
some circumstances it may be appropriate, in explaining the nature of the modification, to refer
to or describe the work o the expert (including the identity of the expert and the extent of the
expert’s involvement). In these circumstances, the auditor would obtain the permission of the
expert before making such a reference. If permission is refused and the auditor believes a
reference is necessary, the auditor may need to seek legal advice.

AUDIT EVIDENCE – ADDITIONAL CONSIDERATIONS ON SPECIFIC ITEMS
EXTERNAL CONFIRMATIONS
AUDIT DOCUMENTATION
PSA 500(REVISED)
AUDIT EVIDENCE
1. The auditor should obtain sufficient appropriate audit evidence to be able to draw reasonable
conclusions on which to base the audit opinion
2. “Audit Evidence” is all the information used by the auditor in arriving at the conclusions on
which the opinion is based, and includes the information contained in the accounting records
underlying the financial statements and other information
3. Accounting records generally include:
 The records of initial entries and supporting records, such as checks and records
of electronic fund transfers;
 Invoices
 Contracts
 The general and subsidiary ledgers, journal entries and other adjustments to the
financial statements that are not reflected in formal journal entries; and
 Records such as work sheets and spreadsheets supporting cost allocations,
computations, reconciliations and disclosures
4. Other information that the auditor may use as audit evidence includes:
 Minutes of the meetings
 Confirmations from third parties
 Analysts’ reports
 Comparable data about competitors (benchmarking)
 Control manuals
 Information obtained by auditors from such audit procedures as inquiry,
observation, and inspection; and
 Other information developed by, or available to, the auditor that permits the
auditor to reach conclusions through valid reasoning
Sufficient appropriate evidence
1. Sufficiency is the measure of the quantity of audit evidence
2. Appropriateness is the measure of the quality of audit evidence; that is, its relevance and its
reliability in providing support for, or detecting material misstatements in, the classes of
transactions, account balances, and disclosures and related assertions.
3. The following generalizations can be made about the reliability of audit evidence:
a. Audit evidence I more reliable when it is obtained from independent sources
outside the entity
b. Audit evidence that is generated internally is more reliable when the related
controls imposed by the entity are effective
c. Audit evidence obtained directly by the auditor (for example, observation of the
application of a control) is more reliable than audit evidence obtained indirectly or
by inference (for example, the inquiry about the application of control)
d. Audit evidence is more reliable when it exists in a documentary form, whether
paper, electronic, or other medium (for example, contemporaneously written
record of a meeting is more reliable than a subsequent oral representation of the
matters discussed)
e. Audit evidence provided by original documents is more reliable than audit evidence
provided by photocopies or facsimiles
4. An audit rarely involves the authentication of documentation, nor is the auditor trained as or
expected to be an expert in such authentication
17
5. When information produced by the entity is used by the auditor to perform audit procedures,
the auditor should obtain audit evidence about the accuracy and completeness of the
information
6. In forming an audit opinion, the auditor does not examine all the information available because
conclusions ordinarily can be reached by using sampling approaches and other means of
selecting items for testing.
The use of assertions in obtaining audit evidence
1. Management is responsible for the fair presentation of financial statements that reflect the
nature and operations of the entity.
2. In representing that the financial statements are presented fairly, in all material respects, in
accordance with the applicable financial reporting framework, management implicitly or
explicitly makes assertions regarding the recognition, measurement, presentation, and
disclosure of the various elements of financial statements and related disclosures
3. The auditor should use assertions for classes of transactions, account balances, and
presentation and disclosures in sufficient detail to form a basis for the assessment of risks of
material misstatement and the design and performance of further audit procedures
CATEGORIES OF ASSERTIONS
a. Assertions about classes of transactions and events for the period under audit:
1. OCCURRENCE
- transactions and events that have been recorded have
occurred and pertain to the entity
2. COMPLETENESS
- all transactions and events that should have been recorded
have been recorded.
3. ACCURACY
- amounts and other data relating to recorded transactions and
events have been recorded appropriately
4. CUTOFF
- transactions and events have been recorded in the correct
accounting period
5. CLASSIFICATION
- transactions and events have been recorded in the proper
accounts
b. Assertions about account balances at the period end:
1. EXISTENCE
-assets, liabilities, and equity interests exist
2. RIGHTS AND OBLIGATIONS
- the entity holds or controls the right to assets,
and liabilities are obligations of the entity
3. COMPLETENESS
- all assets, liabilities, and equity interests that
should have been recorded have been recorded
4. VALUATION AND ALLOCATION
- assets, liabilities and equity interests are
included in the financial statements at appropriate amounts and any resulting
valuation or allocation adjustments are appropriately recorded
c. Assertions about presentation and disclosure:
1. OCCURRENCE AND RIGHTS AND OBLIGATIONS
 Disclosed events, transactions, and other matters have occurred and
pertain to the entity
2. COMPLETENESS
 All disclosures that should have been included in the financial
statements have been included
3. CLASSIFICATION AND UNDERSTANDABILITY
 Financial information is appropriately presented and described and
disclosures are clearly expressed
4. ACCURACY AND VALUATION
 Financial and other information are disclosed fairly and at appropriate
amounts
Audit procedures for obtaining audit evidence
1. RISK ASSESSMENT PROCEDURES
Obtain an understanding of the entity and its environment, including its internal control,
to assess the risk of material misstatement at the financial statement and assertion
levels
2. TESTS OF CONTROLS
When necessary or when the auditor has determined to do so, test the operating
effectiveness of controls in preventing, or detecting and correcting, material
misstatements at the assertion level
18
3. SUBSTANTIVE PROCEDURES
Detect material misstatements at the assertion level. These include analytical review
procedures and tests of details
Examples of audit procedures
1. INSPECTION
Consists of examining records and documents, whether internal or external in paper
form, electronic form, or other media. Inspection of tangible assets consists of physical
examination of the assets.
2. OBSERVATION
Consists of looking at a process or procedure being performed by others
3. INQUIRY
Consists of seeking information of knowledgeable persons, both financial and
nonfinancial, throughout the entity or outside the entity
4. CONFIRMATION
The process of obtaining a representation of information or of an existing condition
directly from a third party
5. RECALCULATION
Consists of checking the mathematical accuracy of documents or records
6. REPERFORMANCE
The auditor’s independent execution of procedures or controls that were originally
performed as part of the entity’s internal control, either manually or through the use of
CAATs
7. ANALYTICAL PROCEDURES
Consists of evaluations of financial information made by a study of plausible
relationships among both financial and nonfinancial data. It also encompasses the
investigation of identified fluctuations and relationships that are inconsistent with other
relevant information or deviate significantly from predicted amounts.
PSA 501
AUDIT EVIDENCE – ADDITIONAL CONSIDERATIONS ON SPECIFIC ITEMS
Attendance at Physical Inventory Counting
1. When inventory is material to the financial statements, the auditor should obtain sufficient
appropriate audit evidence regarding its existence and condition by attendance at physical
inventory counting unless impracticable.
2. If unable to attend the physical inventory count on the date panned due to unforeseen
circumstances, the auditor should take or observe some physical counts on an alternative date
and, when necessary, perform tests of intervening transactions.
3. Where attendance is impracticable, due to factors such as the nature and location of the
inventory, the auditor should consider whether alternative procedures provide sufficient
appropriate audit evidence of existence and condition to conclude that the auditor need not make
reference to a scope limitation.
4. In planning attendance at the physical inventory count or the alternative procedures, the auditor
would consider:
 The nature of the accounting and internal control systems used regarding inventory.
 Inherent, control, and detection risks, and materiality related to inventory.
 Whether adequate procedures are expected to be established and proper instructions issued
for physical inventory counting.
 The timing of the count.
 The locations at which inventory is held.
 Whether an expert’s assistance is needed.
5. The auditor would review management’s instructions regarding:
 The application of control procedures, for example, the collection of used stocksheets,
accounting for unused stocksheets, and count and recount procedures.
19


Accurate identification of the stage of completion of work in progress, of slow moving,
obsolete or damaged items and inventory by a third party, for example, on consignment.
Whether appropriate arrangements are made regarding the movement of inventory between
areas and the shipping and receipt of inventory before and after the cutoff date.
6. To obtain assurance that management’s procedures are adequately implemented the auditor
would observe employee’s procedures and perform test counts.
7. The auditor would also consider cutoff procedures including details of the movement of inventory
just prior to, during, and after the count so that the accounting for such movements can be
checked at a later date.
8. The auditor would test the final inventory listing to assess whether it accurately reflects actual
inventory counts.
9. When inventory is under the custody and control of a third party, the auditor would ordinarily
obtain direct conformation from the third party as to the quantities and condition of inventory
held on behalf of the entity. Depending on the materiality of this inventory, the auditor would
consider:
 The integrity and independence of the third party.
 Observing, or arranging for another auditor to observe, the physical inventory count.
 Obtaining another auditor’s report on the adequacy of third party’s accounting and internal
control systems for ensuring that inventory is correctly counted and adequately safeguarded.
 Inspecting documentation regarding inventory held by third parties, for example, warehouse
receipts, or obtaining confirmation from other parties when such inventory has been pledged
as collateral.
Procedures regarding litigation and claims
1. The auditor should carry out procedures in order to become aware of any litigation and claims
involving the entity, which may have a material effect on the financial statements.
Such procedures would include:
 Make appropriate inquiries of management including obtaining representations.
 Review board minutes and correspondence with the entity’s lawyers.
 Examine legal expense accounts.
 Use any information obtained regarding the entity’s business including information obtained
from discussions with any in–house legal department.
2. When litigation or claims have been identified or when the auditor believes they may exist, the
auditor should seek direct communication with the entity’s lawyers.
3. The letter, which should be prepared by management and sent by the auditor, should request the
lawyer to communicate directly with the auditor. When it is considered unlikely that the lawyer
will respond to a general inquiry, the letter would ordinarily specify:
 A list of litigation and claims.
 Management’s assessment of the outcome of the litigation or claim and its estimate of the
financial implications, including costs involved.
 A request that the lawyer confirms the reasonableness of management’s assessments and
provides the auditor with further information if the list is considered by the lawyer to be
incomplete or incorrect.
4. The auditor considers the status of legal matters up to date of the audit report.
5. If management refuses to give the auditor permission to communicate with the entity’s lawyers,
this would be a scope limitation and should ordinarily lead to a qualified opinion or a disclaimer of
opinion.
20
Valuation and disclosure of long-term investments
1. When long-term investments are material to the financial statements, the auditor should obtain
sufficient appropriate audit evidence regarding their valuation and disclosure.
2. Audit procedures ordinarily include considering evidence as to whether the entity has the ability
to continue to hold the investments on a long-term basis and discussing with management
whether the entity will continue to hold the investments as long-term investments and obtaining
written representations to that effect.
3. Other procedures would ordinarily include considering related financial statements and other
information, such as market quotations, which provide an indication of value and comparing such
values to the carrying amount of the investments up to the date of the auditor’s report.
Segment information
1. When segment information is material to the financial statements, the auditor should obtain
sufficient appropriate audit evidence regarding its disclosure in accordance with the applicable
financial reporting framework.
2. The auditor considers segment information in relation to the financial statements taken as a
whole, and is not ordinarily required to apply auditing procedures that would be necessary to
express an opinion on the segment information standing alone.
3. Audit procedures regarding segment information ordinarily consist of analytical procedures and
other audit test appropriate in the circumstances.
4. The auditor would discuss with management the methods used in determining segment
information, and consider whether such methods are likely to result in disclosure in accordance
with GAAP and test the application of such methods.
PSA 505
EXTERNAL CONFIRMATIONS
1. External confirmation is the process of obtaining and evaluating audit evidence through a direct
communication from a third party in response to a request for information about a particular item
affecting assertions made by management in the financial statements.
Use of positive and negative external confirmations
2. A positive external confirmation request asks the respondent to reply to the auditor in all cases
either by indicating the respondent’s agreement with the given information, or by asking the
respondent to fill in the information.
3. A negative external confirmation request asks the respondent to reply only in the event of
disagreement with the information provided in the request.
4. Negative confirmation requests may be used to reduce the risk of material misstatement to an
acceptable level when:
 The assessed risk of material misstatement is lower.
 A large number of small balances are involved.
 A substantial number of errors are not expected.
 The auditor has no reason to believe that respondents will disregard these requests.
5. When performing confirmation procedures, the auditor should maintain control over the process
of selecting those to whom a request will be sent, the preparation and sending of confirmation
requests, and the responses to those requests.
6. The auditor should perform alternative procedures where no response is received to a positive
external confirmation request. The alternative audit procedures should be such as to provide the
evidence the evidence about the financial statement assertions that the confirmation request was
intended to provide.
21
7. When the auditor forms a conclusion that the confirmation process and alternative procedures
have not provided sufficient appropriate audit evidence regarding an assertion, the auditor should
undertake additional procedures to obtain sufficient audit evidence.
8. The auditor should evaluate whether the results of the external confirmation process together
with the results from any other procedures performed, provide sufficient appropriate audit
evidence regarding the assertion being audited.
PSA 230 (Revised)
AUDIT DOCUMENTATION
1. The auditor should prepare, on a timely basis, audit documentation that provides:
 a sufficient and appropriate record of the basis for the auditor’s report; and
 evidence that the audit was performed in accordance with PSAs and applicable legal and
regulatory requirements
2. “Audit documentation” means the record of audit procedures performed, relevant audit
evidence obtained, and conclusions the auditor reached (terms such as “working papers” or
“work papers” are also sometimes used).
3. “experience auditor” means an individual (whether internal or external to the firm) who has
reasonable understanding of
 Audit processes;
 PSAs and applicable legal and regulatory requirements
 The business environment in which the entity operates; and
 Auditing and financial reporting issues relevant to the entity’s industry
4. Audit documentation may be recorded on paper or on electronic or other media
5. The auditor should prepare the audit documentation so as to enable an experiences auditor,
having no precious connection with the audit, to understand:
 the nature, timing , and extent of the audit procedures performed to comply with PSAs
and applicable legal and regulatory requirements
 the results of the audit procedures and the audit evidence obtained; and
 significant matters arising during the audit and the conclusions reached thereon
6. in documenting the nature, timing and extent of audit procedures performed, the auditor
should record the identifying characteristics of the specific items or matters beig tested
7. the auditor should document discussions of significant matters with management and others on
a timely basis
8. where, in exceptional circumstances, the auditor judges it necessary to depart from a basic
principle or an essential procedure that is relevant in the circumstances of the audit, the auditor
should document how the alternative audit procedures performed achieved the objective of the
audit, and, unless otherwise clear, the reasons for the departure
9. the auditor should record:
 who performed the audit work and the date such work was completed
 who reviewed the audit work performed and the date and extent of such review
Assembly of the final audit file
10. The auditor should complete the assembly of the final audit file on a timely basis after the date
of the auditor’s report. As PSQC 1 indicates, 60 days after the date of the auditor’s report is
ordinarily an appropriate time limit within which to complete the assembly of the final audit file

AUDIT OF FINANCIAL STATEMENTS
PSA 250
CONSIDERATIONS OF LAWS AND REGULATIONS IN AN AUDIT OF
FINANCIAL STATEMENTS
PSA 260
COMMUNICATIONS OF AUDIT MATTERS WITH THOSE CHARGED
WITH GOVERNANCE
PSA 240 (REVISED 2006)
THE AUDITOR’S RESPONSIBILITY TO CONSIDER FRAUD IN AN AUDIT OF FINANCIALSTATEMENTS
FRAUD refers to an intentional act by one party or more individuals among management, those charged
with governance, employees or third parties, involving the use of deception to obtain an unjust or illegal
advantage
Fraud involves:
 Incentive or pressure to commit fraud
 A perceived opportunity to act or to do so
 Some rationalization of the act
Management fraud
- fraud involving one or more members of management or those charged with
governance
Employee fraud
- fraud involving only employees of the entity
(In either case, there may be collusion within the entity or with third parties outside of the entity)
TWO TYPES OF FRAUD
1. FRAUDULENT FINANCIAL REPORTING
 Involves intentional misstatements including omissions of amounts or disclosures in
financial statements to deceive financial statement users
 often involves management override of controls that otherwise may appear to be
operating effectively
 can be caused by the efforts of management to manage earnings in order to deceive
financial statements users by influencing their perceptions as to the entity’s
performance and profitability
 may be accomplished by the following
 manipulation, falsification (including forgery), or alteration of
accounting records or supporting documentation from which the
financial statements are prepared
 misrepresentation in, or intentional omission from, the financial
statements of events, transactions or other significant information
 intentional misapplication of accounting principles relating to amounts,
classifications, manner of presentation, or disclosure
2. MISAPPROPRIATION OF ASSETS
 Involves the theft of an entity’s assets and is often perpetrated by employees in
relatively small and immaterial amounts
 Can also involve management who are usually more able to disguise or conceal
misappropriations in ways that are difficult to detect
 Often accompanied by false or misleading records or documents in order to conceal the
fact that the aspects are missing or have been pledged without proper authorization
 Can be accompanied in a variety of ways including:
o Embezzling receipts
o Stealing physical assets or intellectual property
o Causing an entity to pay for the goods and services not received
o Using an entity’s assets for personal use
23
Responsibilities of Those charged with Governance and of Management
1. The primary responsibility for the prevention and detection of fraud rests with both those
charged with governance of the entity and with management
2. It is important management, with the oversight of those charged with governance, place a
strong emphasis on fraud prevention, which may reduce opportunities for fraud to take place,
and fraud deterrence, which could persuade in individuals not to commit fraud because of the
likelihood detection and punishment
3. It is the responsibility of those charged with governance of the entity to ensure , through
oversight of management, that the entity establishes and maintains internal control to provide
reasonable assurance with regard to reliability of financial reporting, effectiveness and efficiency
of operations and compliance with applicable law and regulations
4. It is the responsibility of management, with oversight from those charged with governance, to
establish a control environment and maintain policies and procedures to assist in achieving the
objective ensuring, as far as possible, the orderly and efficient conduct of the entity’s business
Inherent limitations of an Audit in the context of Fraud
1. Owing to inherent limitations of an audit, there is an unavoidable risk that some material
misstatements of the financial statements will not be detected, even though the audit is
properly planned and performed in accordance with PSAs
2. The risk of not detecting a material misstatement resulting from fraud is higher than the risk of
not detecting a material misstatement resulting from error because fraud may involve
sophisticated and carefully organized schemes designed to conceal it, such as:
 Forgery
 Deliberate failure to record transactions
 Intentional misrepresentation being made to the auditor
3. The risk of the auditor not detecting a material misstatement resulting from management fraud
is greater than for employee fraud, because management is frequently in a position to directly
or indirectly manipulate accounting records and present fraudulent financial information
4. The subsequent discovery of a material misstatement of the financial statements resulting from
fraud does not, in and of itself, indicate a failure to comply with PSAs
Responsibilities of the auditor for detecting material misstatements due to fraud
1. An auditor conducting an audit in accordance with PSAs obtains reasonable assurance that the
financial statements taken as a whole are free from material misstatement, whether caused by
fraud or error
2. An auditor cannot obtain absolute assurance that material misstatements in the financial
statement will be detected because of such factors as of the following:
 use of judgment
 use of testing
 inherent limitations of internal control
 the fact that much of the audit evidence available to the auditor is persuasive
rather than conclusive in nature
3. The auditor should maintain an attitude of professional skepticism throughput the audit,
recognizing the possibility that a material misstatement due to fraud could exist,
notwithstanding the auditor’s past experience with the entity about the honesty and integrity of
management and those charged with governance
4. Members of the engagement team should discuss the susceptibility of the entity’s financial
statements to material misstatement due to fraud
5. Risk assessment procedures
The auditor should perform risk assessment procedures to obtain an understanding of
the entity and its environment, including its internal control. As part of this work, the
auditor performs the following procedures to obtain information that is used to identify
the risks of material misstatements due to fraud:
1. Makes inquiries of management, of those charged with governance, and of others
within the entity as appropriate and obtains an understanding of how those charged
with governance exercise oversight of management’s processes for identifying and
responding to the risks of fraud and he internal control that management has
established to mitigate these risks
2. Considers whether one or more fraud risk factors are present
3. Considers any unusual or unexpected relationships that have been identified in
performing analytical procedures
4. Considers other information that may be helpful in identifying the risks of material
misstatement due to fraud.
24
Responses to the risks of material misstatement due to fraud
1. The auditor should determine overall responses to address he assessed risks of material
misstatement due to fraud at the financial statement level and should design and perform
further audit procedures whose nature, timing and extent are responsive to the assessed risks at
the assertion level
2. In determining overall responses to address the risks of material misstatement due to fraud at
the financial statement level the auditor should:
 Consider the assignment and supervision of personnel
 Consider the accounting policies used by the entity; and
 Incorporate an element of unpredictability in the selection of the nature, timing
and extent of audit procedures
3. Audit procedures responsive to risks of material misstatement due to fraud at the assertion
level
The auditor’s responses may include changing the nature, timing, and extent of audit
procedures in the following ways:
a. The nature of audit procedures to be performed may need to be changed to obtain
audit evidence that is more reliable and relevant to obtain additional corroborative
information
b. The timing of substantive procedures may need to be modified. The auditor may
conclude that performing substantive testing at or near the period end better addresses
an assessed risk of material misstatement due to fraud
c. The extent of the procedures applied reflects the assessment of the risks of material
misstatement due to fraud. For example, increasing sample sizes or performing
analytical procedures at a more detailed level may be appropriate
4. To respond to the risk of management override of controls, the auditor should design and
perform audit procedures to:
a. Test the appropriateness of journal entries recorded in the general ledger and other
adjustments made in the preparation of the financial statements
b. Review accounting estimates for biases that could result to material misstatement due
to fraud
c. Obtain an understanding of the business rationale of significant transactions that the
auditor become aware of that are outside the normal course of the business for the
entity, or that otherwise appear to be unusual given the auditor’s understanding of the
entity and its environment
Evaluation of audit evidences
1. The auditor should consider whether analytical procedures that are performed at or near the
end of audit when forming an overall conclusion as to whether the financial statements as a
whole are consistent with auditor’s knowledge of the business indicate a previously
unrecognized risk of material misstatement due to fraud
2. When the auditor identifies the misstatement, the auditor should consider whether such a
misstatement may be indicative of fraud and if there is such an indication the auditor should
consider the implications of the misstatement in relation to other aspects of the audit,
particularly the reliability of management representations
3. When the auditor confirms that, or is unable to conclude whether, the financial statements are
materially misstated as a result of fraud, the auditor should consider the implications for the
audit
Management representations
The auditor should obtain written representations from management that:
a. It acknowledges its responsibility for the design and implementation of internal control to
prevent and detect fraud
b. It has disclosed to the auditor the results of its assessment of the risk that the financial
statements may be materially misstated as a result of fraud
c. It has disclosed to the auditor its knowledge of fraud or suspected fraud affecting the entity
involving:
i. Management
ii. Employees who have significant roles in internal control
iii. Others where the fraud could have a material effect on the financial statements
and
d. It has disclosed to the auditor its knowledge of any allegations of fraud, or suspected
fraud, affecting the entity’s financial statements communicated by the employees,
former employees, analysts, regulators or others
25
Communication with management and those charged with governance
1. If the auditor has identified a fraud or has obtained information that indicates that a fraud may
exist, the auditor should communicate these matters as soon as practicable to the appropriate
level of management
2. If the auditor has identified fraud involving management, employers who have significant roles
in internal control, or others where the fraud results in a material misstatement in the financial
statements, the auditor considers seeking legal advice to assist in the determination of the
appropriate course of action
3. If the integrity or honesty of management or those charged with governance is doubted, the
auditor considers seeking legal advice to assist in the determination of the appropriate course of
action
4. The auditor should make those charged with governance and management aware, as soon as
practicable, and at the appropriate level of responsibility, of material weaknesses in the design
or implementation of internal control to prevent and detect fraud which may have come to the
auditor’s attention
5. The auditor’s professional duty to maintain the confidentiality of client information may
preclude reporting fraud to a party outside the client the entity. However, the duty of
confidentiality may be overridden by regulatory requirements
Auditor unable to continue the engagement
1. If , as a result of a misstatement resulting from fraud or suspected fraud, the auditor encounters
exceptional circumstances that bring into question the auditor’s ability to continue performing
audit, the auditor should:
a. Consider the professional and legal responsibilities applicable in the circumstances,
including whether there is a requirement for the auditor to report to the person or
persons who made the audit appointment or, I some cases, to regulatory authorities
b. Consider the possibility of withdrawing from the engagement; and
c. If the auditor withdraws:
i. Discuss the appropriate level of management and those charged with
governance the auditor’s withdrawal from the engagement and the reasons for
the withdrawal; and
ii. Consider whether there is a professional or legal requirement to report to the
person or persons who made the audit appointment or, in some cases, to
regulatory authorities, the auditor’s withdrawal from the engagement and the
reasons for the withdrawal
Documentation
1. The documentation of the auditor’s understanding of the entity and its environment and the
auditor’s assessment of the risks of material misstatement should include:
a. The significant decisions reached during the discussion among the engagement
team regarding the susceptibility of the entity’s financial statements to material
misstatement due to fraud
b. The identified and assessed risks of material misstatement due to fraud at the
financial statement level and at the assertion level
2. The documentation of the auditor’s responses to the assessed risks of material misstatement
should include:
a. The overall responses to the assessed risks of material misstatement due to fraud at
the financial statement level and the nature, timing and extent of audit procedure,
and the linkage of those procedures with the assessed risks of material
misstatement due to fraud at the assertion level
b. The results of the audit procedures, including those designed to address the risk of
management override of controls
3. The auditor should document the communications about fraud made to management, those
charged with governance, regulators and others
4. When the auditor has concluded that the presumption that there is a risk of material
misstatement due to fraud related to revenue recognition is not applicable in the circumstances
of the engagement, the auditor should document the reasons for that conclusion

PSA 250
CONSIDERATION OF LAWS AND REGULATIONS IN AN AUDIT OF FINANCIAL STATEMENTS
1. “Noncompliance” as used in PSA 250 refers to acts of omission or commission by he entity being
audited, either intentional and unintentional, which are contrary to the prevailing laws and
regulations
2. Noncompliance does not include personal misconduct (unrelated to the business activities of
the entity) by the entity’s management or employees
3. When planning and performing audit procedures and in evaluating and reporting the results
thereof, the auditor should recognize that noncompliance by the entity with laws and regulation
may materially affect the financial statements
Responsibility of management for the compliance with laws and regulations
1. It is management’s responsibility to ensure that the entity’s operations conducted in accordance
with laws and regulations
2. The responsibility for the prevention and detection of noncompliance rests with management
3. The following policies and procedures, among others, may assist management in discharging its
responsibilities for the prevention and detection of noncompliance:
 Monitoring legal requirements and ensuring that operating procedures are designed to
meet these requirements
 Instituting and operating appropriate systems of internal control
 Developing, publicizing and following a Code of Conduct
 Ensuring employees are properly trained and understand the Code of Conduct
 Monitoring compliance with the Code of Conduct and acting appropriately to discipline
employees who fail to comply with it
 Engaging legal advisors to assist in monitoring legal requirements
 Maintaining a register of significant laws with which the entity has to comply within its
particular industry and a record of complaints
The auditor’s consideration of compliance with laws and regulations
1. The auditor is not, and cannot be held responsible for preventing noncompliance
2. The auditor should plan and perform the audit with an attitude of professional skepticism
recognizing that the audit may reveal conditions or events that would lead to questioning
whether an entity is complying with laws and regulations
3. In order t plan the audit, the auditor should a general understanding of the legal and regulatory
framework applicable to the entity and the industry and how the entity is complying wih that
framework
4. After obtaining the general understanding, the auditor should perform procedures to help
identify instances of noncompliance with those laws and regulations where non compliance
should be considered when preparing financial statements specifically:
a. Inquiring of management as to whether the entity is in compliance with such laws
and regulations
b. On receipt of an inquiry from the proposed auditor, the existing auditor should
advise whether there are any professional reasons why the proposed auditor should
not accept the appointment. If permission from the client to discuss its affairs with
the proposed auditor of denied by the client, the fact should be disclosed to the
propose auditor

AUDIT SAMPLING
(BASED ON PSA 530: AUDIT SAMPLING AND OTHER SELECTIVE TESTING PROCEDURES)
Selecting items of testing to gather audit evidence
When designing audit procedures, the auditor should determine appropriate means of selecting items
for testing. The means available to the auditor are:
a. Selecting all items (100% examination)
b. Selecting specific items
c. Audit sampling
Selecting all items (100% examination)
 Unlikely in the case of tests of control but more common for substantive procedures
 May be appropriate when:
a. The population constitutes a small number of large value items
b. When both inherent risk and control risk are high and other means do not
provide sufficient appropriate audit evidence
c. When the repetitive nature of a calculation or other process performed by a
computer information system makes a 100% examination cost effective
Selecting specific items
 The auditor may decide to select specific items from a population based on such factors as
knowledge of the client’s business, preliminary assessments of inherent and control risks, and
the characteristics of the population being tested
 The judgmental selection of specific items is subject to nonsampling risk
 Specific selected items may include:
 High value or key items
 All items over a certain amount
 Items to obtain information
 Items to test procedures
 While an efficient means of gathering audit evidence, it does not constitute audit sampling. The
results of audit procedures applied to specific items selected cannot be projected to the entire
population
AUDIT SAMPLING
1. “Audit Sampling” involves the application of audit procedures to less than 100% of items with an
account balance or class of transactions
2. Sampling may be statistical or nonstatistical.
I.
Statistical sampling means any approach t sampling that has the following
characteristics:
a. Random selection of a sample
b. Use of probability theory to evaluate sample results
II.
Nonstatistical sampling is a sampling approach that does not have
characteristics (a) and (b).
Audit sampling plan refers to the procedures an auditor applies t accomplish a sampling application. In
aids an auditor I forming conclusions about one r more characteristics or either a particular class of
transactions or a particular account balances
1. ATTRIBUTE SAMPLING
 Applicable to tests of control
 Used to test an entity’s rate of deviation (also called rate of occurrence) from a
prescribed control procedure
2. VARIABLES SAMPLING
 Applicable to substantive test
 Most commonly used to test whether recorded account balances are fairly stated
28
SAMPLING RISK
1. It arises from the possibility that the auditor’s conclusion, based on a sample may be different
from the conclusion reached if the entire population were subjected to the same audit
procedures
2. The confidence level (also called reliability level) is the mathematical complement of the
applicable sampling risk factor
3. It is to be measured and controlled. The auditor controls it by specifying the acceptable level
when developing the sampling design
4. For tests of control, it has the following aspects:
a. Risk of assessing control risk too low (Risk of Overreliance)
 The risk that the auditor would conclude that the control risk is lower
than it actually is
 It affects audit effectiveness and is more likely to lead to an
inappropriate audit opinion
b. Risk of assessing control risk too high (Risk of under reliance)
 The risk that the auditor would conclude that control risk is higher than
actually is
 It affects audit efficiency as it would lead to additional work to establish
that initial conclusions were incorrect
5. For substantive tests, it has the following aspects:
a. Risk of incorrect acceptance
 The risk that the auditor would conclude that a material error exists
when in fact it does
 It affects audit effectiveness and is more likely to lead to an
inappropriate audit opinion
b. Risk of incorrect rejection
 The risk that the auditor would conclude that a material error exists
when in fact it does not
 It affects audit effectiveness as it would lead to additional work to
establish that initial conclusions were incorrect
NONSAMPLING RISK
It arises from factors that cause the auditor to reach an erroneous conclusion for any reason not related
to the size of the sample. For example, most audit evidence is persuasive rather than conclusive, the
auditor might use inappropriate procedures, or the auditor might misinterpret evidence and fail to
recognize an error.
5 STEPS IN ATTRIBUTE SAMPLING PLAN
1. Define the objectives of the plan
2. Define the population
 For example, if an auditor’s objective is to test controls designed to assure
that all shipped goods are invoiced, the population would be defined as all
sipping documents issued during the period not all sales invoices
3. Define the attribute and deviation conditions
 An attribute s a characteristic of control. For example, the supervisor’s
signature of approval on a document. A deviation is the absence of an
attribute
4. Determine the sample size
The sample size is determined by considering the following factors:
a. Risk of assessing control risk too low
b. Tolerable deviation rate
c. Expected population deviation rate
Risk of assessing control risk too low
 There is an inverse relationship between the risk and the sample size. The higher the
acceptable risk, the smaller the sample size
 Because the risk of assessing control risk too low relates to the effectiveness of the
audit, it is kept at a relatively low level by the auditor
Tolerable deviation rate
 This the maximum deviation rate that the auditor is willing to accept
29

The lower the rate of deviation that the auditor is willing to accept, the larger the
sample size needs to be
Expected population deviation rate (expected error)
 The rate of deviation from the prescribed control procedure the auditor expects to find
in the population
 The higher the rate of deviation the auditor expects, the larger the sample size needs to
e so as to be in a position o make a reasonable estimate of the actual rate of deviation
 Factors relevant to the auditor’s consideration of the expected error rate include:
o The auditor’s understanding of the business (in particular, procedures
undertaken to obtain an understanding of the accounting and internal control
systems)
o Charges in the personnel or in the accounting and internal control systems
o The results of audit procedures applied in prior periods
o The results of other audit procedures
5. Determine the method of sample selections
Some commonly used methods are:
a. Random number sampling
 Each item in the population has an equal chance and nonzero probability of selection
 It is usually accomplished by generating random numbers from a random number table
or computer program and tracing them to associated documents or items in th
population
 It is appropriate for both statistical and nonstatistical sampling
b. Systematic selection
 The number of sampling units in the population is divided by the sample size to give a
sample interval, for example 50, and having determined the starting point within the
first 50, each 50th sampling unit is hereafter selected
 Although the starting point may be determined haphazardly, the sample is more likely
to be truly random if it is determined by use of a computerized random number
generator or random number tables
 When using systematic selection, the auditor would need to determine that sampling
interval corresponds with a particular pattern in the population
c. Block selection or cluster sampling
 It involves selecting a block(s) of contiguous items from within the population
 It cannot be ordinarily used in audit sampling because most populations are structured
such that items in sequence can be expected to have similar characteristics to each
other, but different characteristics from items elsewhere in the population
 Although in some circumstances it may be an appropriate audit procedure to examine a
block of items, it would rarely be an appropriate sample selection technique when the
auditor intends to draw valid inferences about the entire population based on sample
d. Haphazard selection
 The auditor selects a sample without following a structured technique
 It is not appropriate when using statistical sampling
e. Stratification
 This involves subdividing the population into subpopulations or strata, i.e., a group of
sampling units which have similar characteristics (often monetary value)
 The strata must be explicitly defined so that each sampling unit can belong to only one
stratum
 This method enables the auditor to direct his efforts towards the items he considers
would potentially contain the greater monetary error
6. Perform sampling plan
7. Evaluate and document results
These include:
a. Determining the sample deviation rate
Sample deviation rate = number of deviations observed
Sample size
b. Determining the maximum population deviation rate (achieved upper deviation limit) and
the allowance for sampling risk (achieved precision)
30

The maximum deviation rate is based on the sample size and the number of
deviations discovered. There are standard tables that yield maximum population
deviation rates at specified risks of assessing control risk too low
 Allowance for sampling risk = Maximum Deviation Rate – Sample Deviation Rate
c. Considering qualitative information
The auditor considers each of the deviation’s nature, importance, and probable cause
d. Reaching an overall conclusion
In assessing control risk, the auditor considers all available quantitative and qualitative
information
COMMONLY USED ATTRIBUTES SAMPLING TECHNIQUES
1. ATTRIBUTE ESTIMATION SAMPLING
 A statistical sampling plan for tests of controls
 Appropriate when an auditor wishes to estimate a true but unknown population
deviation rate
 Uses a fixed sampling plan, i.e., the auditor tests a single sample
2. SEQUENTIAL SAMPLING (ALSO CALLED STOP-OR-GO SAMPLING)
 The sampling plan is performed in several steps
 Following each step, the auditor decides whether to stop or to go on to the next step
 Appropriate when the auditor expects zero or very few deviations
3. DISCOVERY SAMPLING
 Appropriate when the expected deviation rate is near zero and when the auditor’s
objective is to find at least one deviation in a sample if the actual population deviation
rate exceeds or equals a predetermined critical rate (tolerable deviation rate)
STEPS IN A VARIABLE SAMPLING PLAN
1. Determine the objectives of the test
The auditor’s objective is to test the reasonableness of a record account balance, called
hypothesis testing.
2. Define the population and sampling unit
3. Choose an audit sampling technique
a. Statistical vs. Nonstatistical
b. Classical variables sampling vs. Probability-proportional-to-size sampling
4. Determine the sample size
The auditor considers the following:
a. Variation within the population
 Sample size varies in the same direction as the variation in population amounts. As
population variation increases, so does the sample size
 An estimate of population variation is made by determining a population standard
deviation
b. Acceptable risk of incorrect rejection
c. Acceptable risk of incorrect acceptance
d. Tolerable error – the maximum monetary error that may exist in an account balance
without causing the financial statements to be materially misstated
5. Determine the method of sample selection
6. Perform the sampling plan
7. Evaluate the sample results
The following procedures are performed:
a. Projecting the same error to the population
b. Considering sampling risk
c. Considering qualitative information
d. Reaching an overall conclusion
CLASSICAL VARIABLES SAMPLING TECHNIQUES
A. Mean-per-unit estimation
A classical variables sampling technique that projects the sample average to the
population by multiplying the sample average by the number of items in the population
B. Difference estimation
It is a classical variables sampling technique that uses the average difference between
audited amounts and individual recorded amounts to estimate the total audited amount of a
population and an allowance for sampling risk.
31
C. Ratio estimation
A classical variables sampling technique that uses the ratio of audited amounts to
recorded amount in the sample to estimate the total amount of the population and an
allowance for sampling risk
Conditions for using difference and ration estimation
1. Each population item must have a recorded book value
2. Total population book value must be known
3. Expected differences between audited and recorded book values must not be too rare
Choosing between difference and ratio estimation
Ratio estimation is more appropriate when he differences are nearly proportional to book
values.
Difference estimation is more appropriate when there is little or n relationship between the
absolute amounts of the differences and the book values.
PROBABILITY-PROPROTIONAL-TO-SIZE SAMPLING (PPS)
 PPS uses a peso as the sampling unit
 PPS sampling gives each individual peso in the population an equal chance of selection
 PPS is only useful for TESTS OF OVERSTATEMENTS (e.g., assets) since the sample selection
method dictates that the larger the transaction or amount, the more likely that it will be
selected.
 PPS is inappropriate for testing liabilities because understatement is the primary audit
consideration

AUDITING IN A CIS (IT) ENVIRONMENT
1. A CIS environment exists when a computer of any type or size is involved in the processing by
the entity of financial information of significance to the audit, whether the computer is operated
by the entity or by a third party
2. The overall objective and scope of an audit does not change in a CIS environment
3. A CIS environment may affect:
a. The procedures followed in obtaining a sufficient understanding of the accounting
and internal control systems
b. The consideration of the inherent and control risk
c. The design and performance of tests of controls and substantive procedures
4. The auditor should have sufficient knowledge of the CIS to plan, direct, and review the work
performed
5. If specialized skills are needed, the auditor would seek the assistance of a professional
possessing such skills, who may be either on the auditor’s staff or an outside professionals
6. In planning the portions of the audit which may be affected by the client’s CIS environment, the
auditor should obtain an understanding of the significance and complexity of the CIS activities
and the availability of data for use in the audit
7. When the CIS are significant, the auditor should also obtain an understanding of the CIS
environment and whether it may influence the assessment of inherent and control risks
8. The auditor should consider the CIS environment in designing audit procedures to reduce audit
risk to an acceptably low level. The auditor can use either manual audit procedures, computerassisted audit techniques, or a combination of both to obtain sufficient evidential matter
RISK ASSESSMENTS AND INTERNAL CONTROL:
CIS CHARACTERISTICS AND CONSIDERATION
Organizational Structure
Characteristics of a CIS organizational structure includes:
a. Concentration of functions and knowledge
Although most systems employing CIS methods will include certain manual operations,
generally the number of persons involved in the processing of financial information is significantly
reduced.
b. Concentration of programs and data
Transaction and master file data are often concentrated, usually in machine-readable
form, either in one computer installation located centrally or in a number of installations distributed
throughout the entity.
Nature of Processing
The use of computers may result in the design of systems that provide less visible evidence than
those using manual procedures. In addition, these systems may be accessible by a larger number of
persons.
System characteristics that may result from the nature of CIS processing include:
a. Absence of input documents
 Data may be entered directly into the computer system without supporting document
 In some on-line transaction systems, written evidence of individual data entry
authorization (e.g., approval for order entry) may be replaced by other procedures, such
as authorization controls contained in computer programs (e.g., credit limit approval)
b. Lack of visible audit trail
The transaction trail may be partly in machine-readable form and may exist only for a
limited period of time (e.g., audit logs may be set to overwrite themselves after a period of time or
when the allocated disk space is consumed)
c. Lack of visible output
Certain transactions or results of processing may not be printed or only summary data
may be printed
d. Ease of access to data and computer programs
34
Data and computer programs may be assessed and altered at the computer or through
the use of computer equipment at remote locations. Therefore, in the absence of appropriate controls,
there is an increased potential for unauthorized access to, and alteration of, data and programs by
persons inside or outside the entity
Design and procedural aspects
The development of CIS will generally result n design and procedural characteristics that are
different from those found in manual systems. These different design and procedural aspects of CIS
include:
a. Consistency of performance
CIS perform functions exactly as programmed and are potentially more reliable than
annual systems, provided that all transactions types and conditions that could occur are anticipated and
incorporated into the system. On the other hand, a computer program that is not correctly programmed
and tested may consistently process transactions or other data erroneously
b. Programmed control procedures
The nature of computer processing allows the design of internal control procedures in
computer programs
c. Single transaction update of multiple or data base computer files
A single input t the accounting system may automatically update all records associated
with the transaction
d. Systems generated transactions
Certain transactions may be initiated by the CIS itself without the need for an input
document
e. Vulnerability of data and program storage media
Large volumes of data and the computer programs used to process such data may be
stored on portable or fixed storage media, such as magnetic disks and tapes. These media are vulnerable
to theft, loss, or intentional or accidental destruction.
INTERNAL CONTROLS IN A CIS ENVIRONMENT
GENERAL CIS CONTROLS – to establish a framework of overall control over the CIS activities and to
provide a reasonable level of assurance that the overall objectives of internal control are achieved
General CIS controls may include:
a. Organization and management controls – designed to define the strategic direction and
establish an organizational framework over CIS activities, including:
 Strategic information technology plan
 CIS policies and procedures
 Segregation of incompatible functions
 Monitoring of CIS activities performed by third party consultants
b. Development and maintenance controls – designed to provide reasonable assurance that
systems are developed or acquired, implemented and maintained in an authorized and efficient
manner. They also typically are designed to establish control over:
 Project initiation, requirements definition, systems design, testing, data conversion, golive decision, migration to production environment, documentation of new or revised
systems, and user training
 Acquisition and implementation of off-the-shelf packages
 Request for changes to the existing systems
 Acquisition, implementation, and maintenance of system software
c. Delivery and support controls – designed to control the delivery of CIS services and include:
 Establishment of service level agreements against which CIS services are measured
 Performance and capacity management controls
 Disaster recovery/contingency planning, training, and file backup
 Computer operations controls
 Systems security
 Physical and environment controls
d. Monitoring controls – designed to ensure that CIS controls are working effectively as planned.
These include:
 Monitoring of key CIS performance indicators
 Internal external CIS audits
CIS APPLICATION CONTROLS – to establish specific control procedures over the application systems in
order to provide reasonable assurance that all transactions are authorized, recorded and are processed
completely, accurately and on a timely basis. CIS application controls include:
35
a. Controls over Input – designed to provide reasonable assurance that:
 Transactions are properly authorized before being processed by the computer
 Transactions are accurately converted into machine readable form and recorded in the
computer data files
 Transactions are not lost, added, duplicated or improperly changed
 Incorrect transactions are rejected, corrected and, if necessary, resubmitted on a timely
basis.
b. Controls over processing and computer data files – designed to provide reasonable assurance
that:
 Transactions, including system generated transactions, re properly processed by the
computer
 Transactions are not lost, added, duplicated or improperly changed
 Processing errors (i.e., rejected data and incorrect transactions) are identified and
corrected on a timely basis
c. Controls over output – designed to provide reasonable assurance that:
 Results of processing are accurate
 Access to output is restricted to authorized personnel on a timely basis
 Output is provided to appropriate authorized personnel on a timely basis
Review of general CIS controls
General CIS controls that relate to some or all applications are typically interdependent controls
in that their operation is often essential to the effectiveness of CIS application controls. Accordingly, it
may be more efficient to review the design of the general controls before reviewing the application
controls.
Review of CIS application controls
CIS application controls which the auditor may wish to test include:
a. Manual controls exercised by the user
b. Controls over system output
c. Programmed control procedures
CIS ENVIRONMENTS – STAND-ALONE PERSONAL COMPUTERS
1. A personal computer (PC) can be used in various configurations. These include:
a. A stand-alone workstation operated by a single user or a number of users at
different times;
b. A workstation which part of a Local Area Network (LAN) of PCs; and
c. A workstation connected to a server
2. In a stand-alone PC environment, it may not be practicable or cost-effective for management to
implement sufficient controls to reduce the risks of undetected error to a minimum level
3. After obtaining the understanding of the accounting system and control environment, the
auditor may find it more cost-effective not to make a further review of general controls or
application controls, but concentrate audit efforts on substantive procedures.




Combines in-line/ real time and on-line/ batch processing

information that has been extracted from the most recent version of
the master file. Inquiries are made from this memo file
These same transactions are added to a transaction file for subsequent
validation and updating of the master file on a batch basis
d. On-line/ inquiry
 Restricts users at terminal devices to making inquiries of master file

1. Auditing around the computer – the auditor ignores or bypasses the computer processing
function of an entity’s EDP system
2. Auditing with the computer – the computer is used as an audit tool
3. Auditing through the computer – the auditor enters the client’s system and examines directly
the computer and its system and application software
COMPUTER ASSISTED AUDIT TECHNIQUES FOR TESTS OF CONTROLS
I.
Program analysis – techniques that allow the auditor to gain an understanding of the client’s
program
1. Code review – involves actual analysis of the logic of the program’s processing
routines
2. Comparison programs – programs that allow the auditor to compare computerized
files
3. Flowcharting software – used to produce a flowchart of a program’s logic and may
be used both in mainframe and microcomputer environments
4. Program tracing and mapping – program tracing is a technique in which instruction
executed is listed along with control information affecting that instruction. Program
mapping identifies sections of code which may be potential source of abuse
5. Snapshot – this technique “takes a picture” of the status of program execution,
intermediate results, or transaction data at specified processing points I the
program processing
II.
Program testing – involves the use of auditor-controlled actual or simulated data
1. Historical audit techniques – test the audit computer controls at a point in time
a. Test data
 A set of dummy transactions specifically designed to test the control
activities that management claims to have incorporated into the
processing programs
 Shifts control over processing to the auditor by using the client’s
software to process auditor-prepared test data that includes both valid
and invalid conditions
 It embedded controls are functioning properly, the client’s software
should detect all the exceptions planted in the auditor’s test data
 Ineffective if the client does not use the software tested
b. Base case system evaluation (BCSE)
 Develops test data that purports to test every possible condition that an
auditor expects a client’s software will confront
 Provides an auditor with much more assurance than test data alone, but
expensive to develop and therefore cost-effective only in large
computer systems
c. Integrated test facility (ITF)
 A variation of test of data whereby simulated data and actual data are run simultaneously
with the client’s program and computer results are compared with auditor’s predetermined
results
 It provides assurance that the software tested is actually used to prepare financial reports
d. Parallel simulation
 It involves of processing client’s live (actual) data utilizing an auditor’s generalized audit
software
 If an entity’s control have been operating efficiently, the client’s software should generate the
same exceptions as the auditor’s software
 It should be performed on a surprise basis, I possible
e. Controlled reprocessing
 A variation of parallel simulation, it involves processing of actual client data through a copy of
the client’s application program
2. Continuous audit techniques – test the audit computer controls throughout a
period.
a. Audit modules – programmed audit routines incorporated into an
application program that are designed to perform an audit function such as
a calculation, or logging activity
b. Systems control audit review files (SCARFs) – log that collect transaction
information for subsequent review and analysis by the auditor
c. Audit hooks – “exists” in an entity’s computer program that allows an
auditor to insert commands for audit processing
39
d. Transaction tagging – a transaction record is tagged and then traced
through critical control points in the information system
e. Extended records – this technique attaches additional audit data which
would not otherwise be saved to regular historic records and thereby helps
to provide a more complete audit trail
III.
Review of operating system and other system software
1. JOB ACCOUNTING DATA/ OPERATING SYSTEM LOGS – these logs that track
particular functions, include reports of the resources use by the computer system.
The auditor may be able to use them to review the work processed, to determined
whether unauthorized applications were processed and to determine that
authorized applications were processed properly
2. LIBRARY MANAGEMENT SOFTWARE – this logs changes in programs, program
modules, job control language, and other processing activities
3. ACCESS CONTROL AND SECURITY SOFTWARE – this restricts access to computers to
authorized personnel through techniques such as only allowing certain users with
“read-only” access or through use of an encryption
COMPUTERIZED AUDIT TOOLS
1. AUDIT SOFTWARE – computer programs used to process data of audit significance from the
client’s accounting system
a. Package programs (generalized audit software)
1. Reading computer files
2. Selecting samples
3. Performing calculations
4. Creating data files
5. Printing reports in an auditor-specified format
b. Purpose written programs (special purpose or custom designed programs)
c. Utility programs – they are generally not designed for audit purposes
2. Electronic spreadsheets – contain a variety of predefined mathematical operations and
functions that can be applied to data entered into the cells of a spreadsheet
3. Automated work paper software – designed to generate a trial balance, lead schedules, and
other reports useful for the audit. The schedules and reports can be created once the auditor
has either manually entered or electronically imported through using the client’s account
balance information into the system
4. Text retrieval software – allow user to view any text that ia available in an electronic format. The
software program allows the user to browse through text files much as a user would browse
through books.
5. Database management systems
6. Public databases
7. Word processing software
Factors to consider in using CAAT
1. Degree of technical competence in CIS
2. Availability of CAAT and appropriate computer facilities
3. Impracticability of manual tests
4. Effectiveness and efficiency
5. Timing of tests
Controlling the CAAT application
Procedures to control the use of AUDIT SOFTWARE may include:
1. Participating in the design and testing of computer programs
2. Checking the coding of the program
3. Requesting the client’s CIS personnel to review the operating system instructions
4. Running the audit software on small test files before running them on main data files
5. Ensuring that the correct files were used
6. Obtaining evidence that the audit software functioned as planned
7. Establishing appropriate security measures to safeguard against manipulations of the entity’s
data files
Procedures to control the use of TEST DATA may include:
1. Controlling the sequence of submission of test data where it spans several processing cycles
2. Performing test runs
3. Predicting the results of test data
4. Confirming that the current version of the program was used
5. Obtaining reasonable assurance that the programs used to process the test data were used by
the entity throughout the applicable audit period

COMPLETING THE AUDIT
The procedures to wrap-up an audit engagement are:
1. Review for related party transactions
2. Review for subsequent events
3. Make inquiries of a client’s legal counsel
4. Search for unrecorded liabilities
5. Perform final review stage analytical procedures
6. Review adequacy of disclosures using a disclosure checklist that list all specific disclosures
required by GAAP and the SEC, if appropriate
7. Review of working papers
8. Form an opinion
RELATED PARTY TRANSACTIONS
Identifying transactions with related parties
The following procedures may identify material transactions with known related parties or indicate the
existence of previously unknown related parties:
1. Provide personnel performing all segments of the audit with the names of known related parties
2. Review the minutes of meetings of the board of directors and committees
3. Review filings with SEC and other regulatory agencies
4. Review conflict-of-interest statements obtained from the client’s management
5. Review business transacted with major customers, suppliers, borrowers, and lenders for
indications of undisclosed relationships
6. Consider whether unrecognized transactions are occurring, such as receiving or providing
accounting, management, or other services at no charge
7. Review accounting records for large, unusual, or nonrecurring transactions or balances,
especially those near the end of the period
8. Review invoices from law firms
9. Review confirmations of loan receivable and payable for guarantees.
Examining identified related party transaction
1. Obtain an understanding of the business purpose of the transaction
2. Examine invoices, executed copies of agreements, contracts, and other documents
3. Determine whether the transaction has been approved by the board of directors or other
officials
4. Test for reasonableness the compilation of amounts to be disclosed or considered for disclosure
5. Arrange for the audits of intercompany balances to be performed as of concurrent dates, even
the fiscal years differ, and for the examination of the specified, important, and representative
related party transactions by the auditor for each of the parties with appropriate exchange of
relevant information
6. Inspect or confirm and obtain satisfaction concerning the transferability and value of the
collateral
EVENTS AFTER THE BALANCE SHEET DATE (subsequent events)
(Based on PSA 560 – subsequent events)
1. Events after the balance sheet date are those events, both favorable and unfavorable, that
occur between the balance sheet date and the date when the financial statements are
authorized for issue
2. The following procedures are typically performed at or near the completion of the fieldwork to
detect subsequent events:
a. Read the latest available interim financial statements and compare them with the
financial statements being reported on
b. Read the available minutes of the meetings of stockholders, directors, and
appropriate committees
c. Assemble pertinent findings resulting from inquiries of legal counsel and other
auditing procedures for litigation, claims, and assessments
d. Obtain a letter of representation from management
41
3. When the auditor becomes aware of events which materially affect the financial statements, the
auditor should consider whether such events are properly accounted for and adequately
disclosed in the financial statements
INQUIRIES OF CLIENT’S LEGAL COUNSEL
1. The auditor is required to communicate directly with a client’s attorney about liabilities arising
from litigations, claims, and assessments
2. A list of legal issues should be prepared by the client’s management, rather than the client’s
attorney. This information is sent by the auditor to the auditor to the attorney, requesting
information about:
a. Pending or threatened litigation, claims, and assessments
b. Unasserted claims and assessments
3. The client should request the attorney to furnish the following information for all pending or
threatened litigation, claims, and assessments, and to comment on differences between the
attorney’s and management’s views:
a. A description of the nature of the matter, progress to date, and action that client
intends to take
b. An evaluation of the likelihood of an unfavorable outcome and an estimate, if one
can be made, of the amount or range of potential loss
c. A statement that management’s list of pending or threatened claims is complete, or
identification of any omissions
4. The attorney’s refusal to reply to the audit inquiry is a SCOPE LIMITATION that may affect the
audit report
5. In the case of unasserted claims which the client has not disclosed, the lawyer is not required to
note them in his or her reply to the auditor. However, the lawyer is generally required to inform
the client of the omission and to consider withdrawing if the client fails to inform the auditor
MANAGEMENT REPRESENTATION LETTER
(BASED ON PSA 560 – MANAGEMENT REPRESENTATIONS)
1. The representation letter
a. Confirms the oral representations given by management to the auditor and reduces
the possibility of misunderstanding between the client and the auditor
b. Reminds management of its primary responsibility for the financial statements
c. Addressed to the auditor
d. Dated as of the audit report date
e. Signed by the CEO and the CFO
f. Not a substitute for the application of other necessary auditing procedures
2. If management refuses to provide a representation that the auditor considers necessary, this
constitutes a scope limitation and the auditor should express a qualified opinion or a disclaimer
of opinion
3. Written representations requested from management may be limited to matters that are
considered either individually or collectively material to the financial statements

THE AUDITOR’S REPORT ON FINANCIAL STATEMENTS
(Based on PSA 700 revised – The Independent Auditor’s Report
On a Complete Set of General Purpose Financial Statements)
INDEPENDENT AUDITOR’S REPORT
[Appropriate addressee]
Report on the financial statements
[This subheading is unnecessary in circumstances when the second subheading “Report on Other Legal
and Regulatory Requirements” is not applicable.
We have audited the accompanying financial statements of ABC Company which comprise a balance
sheet as at date December 31, 20X1, and the income statement, statement of changes in equity and
cash flow statement for the year ended, and a summary of significant accounting policies and other
explanatory notes.
Management’s responsibility for the financial statements
Management is responsible for the preparation and fair presentation of these financial statements in
accordance with the Philippine Financial Reporting Standards. This responsibility includes: designing,
maintaining and implementing internal control relevant to the preparation and fair presentation of
financial statements that are free from material misstatements, whether due to fraud or error; selecting
and applying appropriate accounting policies; and making accounting estimates that are reasonable in
circumstances.
Auditor’s responsibility
Our responsibility is to express an opinion on these financial statements based on our audit. We
conducted our audit in accordance with Philippine Standards on Auditing. Those standards require that
we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance
whether the financial statements are free from material misstatement. An audit involves performing
procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The
procedures selected depend upon the auditor’s judgment, including the assessment of the risks of
material misstatements on the financial statements whether due to fraud or error. In making those risk
assessments; the auditor considers internal control relevant to the entity’s preparation and fair
presentation of the financial statements in order to design audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the effectiveness of the internal
control of the entity. An audit also includes evaluating the appropriateness of the accounting policies
used and the reasonableness of accounting estimates made by the management, as well as evaluating
the overall presentation of the financial statements.
We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for
our audit opinion.
Opinion
In our opinion, the financial statements fairly, in all material respects, the financial position of ABC
Company as of December 31, 20X1, and of its financial performance and its cash flows for the year then
ended in accordance with the Philippine Financial Reporting Standards.

MODIFICATIONS TO THE INDEPENDENT AUDITOR’S REPORT (BASED ON PSA 701)
Matters that do not affect the auditor’s opinion
 You may add an emphasis of matter paragraph to the report to highlight a matter
affecting the financial statements which is included in the note of the financial
statements that more extensively discuss the matter
 The paragraph would preferably be included after the opinion paragraph but before the
section on any other reporting responsibilities, if any.
 Emphasis of matter paragraph is used to highlight the existence of:
 Material uncertainty relating to the event or condition that may cast significant
doubt on the entity’s ability to continue as a going concern; or
 Significant uncertainty (other than a going concern problem), the resolution of
which is dependent upon future events and which may affect the financial
statements
 Emphasis of matter paragraph to report on matters other than those affecting the
financial statements. For example, if an amendment to other information in a document
containing audited financial statements is necessary and the entity refuses to make an
amendment
Example of an emphasis of matter paragraph relating to a going concern problem:
Without qualifying our opinion, we draw attention to Note X in the financial statements which
indicates that the Company incurred a net loss of P_____ during the year ended December 31,20X1 and,
as of date, the company’s current liabilities exceeded its total assets by P_____. These conditions, along
with other matters, as set forth in Note X, indicate the existence of a material uncertainty which may
cast significant doubt about the Company’s ability to continue as a going concern.
Matters that affect the auditor’s opinion
 If the following circumstances exists that the auditor may not be able to conclude an
unqualified judgment and the effect of the matter is or may be material to the financial
statements:
 There is a limitation on the scope of the auditor’s work. – could lead to a
qualified opinion or a disclaimer of opinion
 A disagreement with the management regarding the acceptability of the
accounting policies selected the method of their application on the
adequacy of financial statement disclosures. Could lead to a qualified
opinion or an adverse of opinion.
Qualified opinion
 Should be expressed when the auditor concludes that the unqualified opinion cannot be
expressed but that the effect of any disagreement with management, or limitation on
scope is not so material and pervasive as to require an adverse opinion or a disclaimer
of opinion.
 A qualified opinion should be expressed as being “except for” the effects of the matter
to which the qualification relates.
Adverse opinion
 Should be expressed when the effect of the disagreement is so material and pervasive
to the financial statements that the auditor concludes that a qualification of the report
is not adequate to disclose the misleading or incomplete nature of the financial
statements.
Disclaimer of Opinion
 Should be expressed when the possible effect of a limitation on the scope is so material
and pervasive that the auditor has not been able to obtain sufficient appropriate audit
evidence and accordingly is unable to express an opinion on the financial statements.

SUBSEQUENT EVENTS (BASED ON PSA 560)
1. The auditor should consider the effect of subsequent events on the financial statements
and on auditor’s report.
Events occurring up to the date of the auditor’s report
2. The auditor should perform procedures designed to obtain sufficient appropriate audit
evidence that all events up to date of the auditor’s report that may require adjustment
of, or disclosure in, the financial statements have been identified.
3. When the auditor becomes aware of events which materially affect the financial
statements, the auditor should consider whether such events are properly accounted
for and adequately disclosed in the financial statements.
Facts discovered after the date of the auditor’s report but before the financial statements are
issued
4. During the period from the date of the auditor’s report to the date the financial
statements are issued:
o The responsibility to inform the auditor of facts which may affect the financial
statements rests with management
o When the auditor becomes aware of the facts that will materially affect the
financial statements, the auditor should:
 Consider whether the financial statements needed amendment
 Discuss the matter with the management
 Take the action appropriate in the circumstances
47
5. When the management amends the financial statements, the auditor would carry out
the procedures necessary in the circumstances and would provide management with a
new report on the amended financial statements
6. The new auditor’s report would be dated not earlier than the date the amended
financial statements are signed or approved and, accordingly, the procedures to identify
subsequent events would be extended to the date of the new auditor’s report
7. When management does not amend the financial statements but the auditor believes
they need to be amended and the auditor’s report has not been released to the entity,
the auditor should express a qualified opinion or an adverse opinion.
Facts discovered after the financial statements have been issued
8. After the financial statements have been issued, the auditor has no obligation to make
any inquiry regarding such financial statements.
9. When, after the financial statements have been issued, the auditor becomes aware of a
fact which existed at the date of the auditor’s report and which, if known at date, may
have caused the auditor to modify the auditor’s report, the auditor should:
o Consider whether the financial statements need revision
o Discuss the matter with management
o Take the appropriate action in the circumstances
10. When management revises the financial statements, the auditor would:
o Carry out the audit procedures necessary in the circumstances
o Review the steps taken by management to ensure that anyone in receipt of the
previously issued financial statements together with the auditor’s report thereon
is informed of the situation.
o Issue a new report on the revised financial statements:
 Include an emphasis of a matter paragraph.
 Would be dated earlier than the date the revised financial statements are
approved
 The auditor is permitted to restrict the audit procedures regarding the
revised financial statements to effects of the subsequent event that
necessitated the revision.
11. It may not be necessary to revise the financial statements and issue a new auditor’s
report when issue of the financial statements for the following period is imminent,
provided appropriate disclosures are to be made in such statements
USING THE WORK OF ANOTHER AUDITOR (BASED ON PSA 600)
1. The principal auditor is the auditor with responsibility for reporting on the financial
statements of an entity when those financial statements include financial information of
one or more components audited by another auditor
2. The auditor should consider whether the auditor’s own participation is sufficient to be
able to act as principal auditor. The following would be considered:
o The materiality of the portion of the financial statements which the principal
auditor audits
o The principal auditor’s degree of knowledge regarding the business of the
components
o The risk of material misstatements in the financial statements of the
components audited by the other auditor
o The performance of additional procedures as set out in PSA 600 regarding the
components audited by other auditor resulting in the principal auditor having
significant participation in such audit
3. When planning to use the work of another auditor, the principal auditor should:
o Consider the professional competence of the other auditor in the context of
specific assignment
o Perform procedures to obtain sufficient appropriate audit evidence that the
work of the other auditor is adequate for the principal auditor’s purposes in the
context of the specific assignment
o Consider the significant findings of the other auditor
4. Reporting conclusions
48
o When the principal auditor concludes that the work of the other cannot be used
and the principal auditor has not been able to perform sufficient additional
procedures regarding financial information of the component audited by the
other auditor, the principal auditor should express a qualified or a disclaimer of
opinion because of a scope of limitation.
o If the auditor issues or intend to issue, a modified auditor’s report, the principal
auditor would consider whether the subject of modification is of such a nature
and significance, in relation to the financial statements of the entity on which the
principal auditor is reporting that a modification on the principal auditor’s report
is required.
5. Division of responsibility
o When the principal auditor bases the audit opinion on the financial statements
taken as a whole solely upon the report of another auditor regarding the audit of
one or more components, the principal auditor’s report should state this fact
clearly and should indicate the magnitude of the portion of the financial
statements audited by the other auditor.
COMPARATIVES (BASED ON PSA 710)
1. Two broad financial reporting frameworks for comparatives:
CORRESPONDING FIGURES
o For the prior periods, these are an integral part of the current period financial
statements and have to be read in conjunction with the amounts and other
disclosures relating to the current period.
o These are not presented as complete financial statements capable of standing
alone
o The auditor should obtain sufficient appropriate audit evidence that the
corresponding figures meet the requirements of GAAP in the Philippine
o The auditor should assess whether:
 Accounting policies used for the corresponding figures are consistent
with those of the current period or whether appropriate adjustments
and/or disclosures have been made
 Corresponding figures agree with the amounts and other disclosures
presented in prior period or whether appropriate adjustments and/or
disclosures have been made
COMPARATIVE FINANCIAL STATEMENTS
 These comparative financial statements for the prior period(s) are considered separate
financial statements.
 These are presented for comparison with the financial statements of the current period,
but do not form part of the current period financial statements
 The auditor should obtain sufficient appropriate evidence that the comparative financial
statements meet the requirements of GAAP in the Philippines
 The auditor should assess whether:
o Accounting policies of the prior period are consistent with those of the current
period or whether appropriate adjustments and/or disclosures have been made
o Prior period figures presented agree with the amounts and other disclosures
presented in the prior period or whether appropriate judgments and disclosures
have been made
REPORTING – CORRESPONDING FIGURES
1. The comparatives are not specifically identified in the audit report because the auditor’s
opinion is on the current period financial statements as a whole, including the
corresponding figures
2. When the auditor’s report on the prior period, as previously issued, included an opinion
other than unqualified and the matter which gave rise to the modification is:

AUDITING THEORY
CPA REVIEW
REPORTS – OTHER ASSURANCE AND RELATED SERVICES
ENGAGEMENTS TO REVIEW FINANCIAL STATEMENTS
(Based on PSRE 2400)
1.
The objective of a review of financial statements is to enable an auditor to state whether,
on the basis of procedures which do not provide all the evidence that would be required in
an audit, anything has come to the auditor’s attention that causes the auditor to believe
that the financial statements are not prepared, in all material respects, in accordance with
Philippine Financial Reporting Standards (negative assurance).
2.
For the purpose of expressing negative assurance in the review report, the auditor should
obtain sufficient appropriate audit evidence primarily through inquiry and analytical
procedures to be able to draw conclusions.
3.
A review engagement provides a moderate level of assurance that the information subject
to review is free of material misstatement. This is expressed in the form of negative
assurance.
4.
In planning a review of financial statements, the auditor should obtain or update the
knowledge of the business including consideration of the entity’s organization, accounting
systems, operating characteristics and the nature of its assets, liabilities, revenues, and
expenses.
5.
Procedures for the review of financial statements will ordinarily include:
 Obtaining an understanding of the entity’s business and the industry in which I
operates.
 Inquiries concerning the entity’s




Analytical procedures designed to identify relationships and individual items that
appear unusual. Examples:






Accounting principles and practices.
Procedures for recording, classifying, and summarizing transactions, and accumulating
information for disclosures.
Actions taken at meeting of stockholders, the board of directors, and committees.
Comparison of the financial statements with those from prior periods.
Comparison of the statements with anticipated results, such as previously prepared budgets
or forecasts.
Study of the relationships of elements of the financial statements that are expected to form a
predictable pattern.
Reading the financial statements to consider, on the basis of information coming to
the auditor’s attention, whether the financial statements appear to conform to basis
of accounting indicated.
Obtaining reports from other auditor’s, if any if considered necessary, who have been
engaged to audit or review the financial statements of components of the entity.
Inquiries of persons having responsibility for financial and accounting matters
concerning, for example:





Whether all transactions have been recorded.
Whether the financial statements have been prepared in accordance with the basis of
accounting indicated.
Changes in the entity’s business activities and accounting principles and practices.
Matters as to which questions have arisen in the course of applying the foregoing procedures.
Obtaining written representations from managements when considered appropriate.
53
6.
If the auditor has reason to believe that the information subject to review may be
materially misstated, the auditor should carry out additional or more extensive procedures
as are necessary to be able to express negative assurance or to confirm that a modified
report is required.
EXAMPLE OF AN UNQUALIFIED REVIEW REPORT
We have reviewed the accompanying balance sheet of AAA Company at December 31, 19XX, and the related
statements of income, changes in equity and cash flows for the year then ended. These financial statements are the
responsibility of the Company’s management. Our responsibility is to issue a report on these financial statements
based on our review.
We conducted our review in accordance with the Philippines Standards on Review Engagements 2400. This
Standard requires that we plan and perform the review to obtain moderate assurance as to whether the financial
statements are free of material misstatement. A review is limited primarily to inquiries of company personnel and
analytical procedures applied to financial data and thus provide less assurance than an audit. We have not performed
an audit an accordingly, we do not express an audit opinion.
Based on our review, nothing has come to our attention that causes us to believe that the accompanying financial
statements are not presented fairly, in all material respects in accordance with Philippine Financial Reporting
Standards.
ENGAGEMENTS TO PERFORM AGRRED-UPON PROCEDURES
REGARDING FINANCIAL INFORMATION (Based on PSRS 4400)
1.
An engagement to perform agreed-upon procedures may involve the auditor in performing
certain procedures concerning:



Individual items of financial data (for example, accounts payable, accounts receivable, purchases from
related parties and sales and profits of a segment of an entity).
A financial statement (for example, a balance sheet).
A complete set of financial statements.
2.
The objective of an agreed-upon procedures engagement is for the auditor to carry out
procedures of an audit nature to which the auditor and the entity and any appropriate
third parties have agreed and to report on factual findings.
3.
As the auditor simply provides a report of the factual findings of agreed-upon procedures,
no assurance is expressed. Users of the report assess for themselves the procedures and
findings reported by the auditor and draw their own conclusions from the auditor’s work.
4.
The report is restricted to those parties that have agreed to procedures to be performed
since others, unaware of the reasons for the procedures, may misinterpret the results.
5.
Independence is not a requirement for an agreed-upon procedures engagement.
REPORTING
6.
The report on an agreed-upon procedures engagement needs to describe the purpose and
the agreed-upon procedures of the engagement in sufficient detail to enable the reader to
understand the nature and the extent of the work performed.
7.
The report of factual findings should contain:








Title;
Addressee (ordinarily the client who engaged the auditor to perform the agreed-upon procedures);
Identification of specific financial or non-financial information to which the agreed-upon procedures
have been applied;
A statement that the procedures performed was those agreed upon with the recipient;
A statement that the engagement was performed in accordance with the Philippine Standard on Related
Services applicable to agreed upon procedures engagements;
A statement that the auditor is not independent of the entity if such is the case;
Identification of the purpose for which the agreed-upon procedures were performed;
A listing of the specific procedures performed;
54








A description of the auditor’s factual findings including sufficient details of errors and exceptions found;
A statement that the procedures performed does not constitute either an audit or a review and, as such,
no assurance is expressed;
A statement that had the auditor performed additional procedures, an audit or a review, other matters
might have come to light that would have been reported;
A statement that the report is restricted to those parties that have agreed to the procedures to be
performed;
A statement (when applicable) that report relates only to the elements, accounts, items, or financial and
non-financial information specified and that it does not extend to the entity’s financial statements taken
as a whole;
Date of the report;
Auditor’s address; and
Auditor’s signature.
ENGAGEMENTS TO COMPLETE FINANCIAL INFORMATION (Based on PSRS 4410)
1.
A compilation engagement would ordinarily include the preparation of financial
statements (which may or may not be a complete set of financial statements) but may also
include the collection, classification, and summarization o other financial information.
2.
The objective of a compilation engagement is for the accountant to use accounting
expertise, as opposed to auditing expertise, to collect, classify and summarize financial
information.
3.
The procedures employed are not designed and do not enable the accountant to express
any assurance on the financial information.
4.
Independence is not a requirement for a compilation engagement. However, where the
accountant is not independent, a statement to that effect would be made in the
accountant’s report.
5.
The accountant should obtain a general knowledge of the business and operations of the
entity and should be familiar with the accounting principles and practices of the industry in
which the entity operates and with the form and content of the financial information that
is appropriate in the circumstances.
6.
The accountant is not ordinarily required to:
 Make any inquiries of management to assess the reliability and completeness of the
information provided;
 Assess internal controls;
 Verify any matters;
 Verify any explanations.
If the accountant becomes aware that information supplied by management is incorrect,
incomplete, or otherwise unsatisfactory, the accountant should consider performing the
above procedures and request management to provide additional information.
If management refuses to provide additional information, the accountant should
withdraw from the engagement, informing the entity of the reasons for the withdrawal.
7.
The accountant should read the compiled information and consider whether it appears to
be appropriate in form and free from obvious material misstatements.
8.
The accountant should obtain an acknowledgement from management of its
responsibility for the appropriate presentation of the financial information and of its
approval of the financial information.
9.
The financial information compiled by the accountant should contain a reference such as
“Unaudited’, “Compiled without Audit or Review,’ or “Refer to the Compilation report’ on
55
each page of the financial information or on the front of the complete set of financial
statements.
Example of a report on an engagement to compile financial statements
On the basis of information provided by the management we have compiled, in accordance with the Philippine
Standard on Related Services applicable to compilation engagements, the balance sheet of XXX Company as of
December 31, 19XX and statements of income, changes in equity and cash flows for the year then ended.
Management is responsible for these financial statements. We have not audited or reviewed these financial
statements and accordingly express no assurance thereon.
THE EXAMINATION OF PROSPECTIVE FINANCIAL INFORMATION
(Based on PSAE 3400)
1.
“PROSPECTIVE FINANCIAL INFORMATION” means financial information based on
assumptions about events that may occur in the future and possible actions by an entity. It
can be in the form of a forecast, a projection, or a combination of both, for example, a one
year forecast plus a five year projection.
2.
A “FORECAST” means prospective financial information prepared on the basis of
assumptions as to future events which management expects to take place and the actions
management expects to take as of the date the information is prepared (best-estimate
assumptions).
3.
A “PROJECTION” means prospective financial information prepared on the basis of:


4.
Hypothetical assumptions about future events and management actions which are not
necessarily expected to take place, such as when some entities are in a start-up phase or are
considering a major change in the nature of operations; or
A mixture of best-estimate and hypothetical assumptions.
Prospective financial information can include financial statement or one or more elements
of financial statements and may be prepared:


As an internal management tool, for example, to assist in evaluating a possible capital
investment; or
For distribution to third parties.
5.
Management is responsible for the preparation and presentation of the prospective
financial information, including the identification and disclosure of the assumptions on
which it is based.
6.
In an engagement to examine prospective financial information, the auditor should obtain
sufficient appropriate evidence as to whether:



Management’s best-estimate assumptions on which the prospective financial
information is based are not unreasonable and, in the case of hypothetical
assumptions, such assumptions are consistent with the purpose of the information.
The prospective financial information is properly presented and all material
assumptions are adequately disclosed, including a clear indication as to whether they
are best-estimate assumptions or hypothetical assumptions; and
The prospective financial information is prepared on a consistent basis with historical
financial statements, using appropriate accounting principles.
7.
The auditor should not express any opinion as to whether the results shown in the
prospective financial information will be achieved.
8.
When reporting on the reasonableness of management’s assumptions, the auditor
provides only a moderate level of assurance.
56
9.
The auditor should not accept, or should withdraw from, an engagement when the
assumptions are clearly unrealistic or when the auditor believes that the prospective
financial information will be inappropriate for its intended use.
10. The auditor should obtain written representations from management regarding the
intended use of the prospective financial information, the completeness of significant
management assumptions and management’s acceptance of its responsibility for the
prospective financial information.
Example of an unmodified report on a forecast
We have examined the forecast (include name of the entity, the period covered by the forecast and provide suitable
identification, such as by reference to page numbers or by identifying the individual statements) in accordance with
Philippine Standard on Assurance Engagements applicable to the examination of prospective financial information.
Management is responsible for the forecast including the assumptions set out in Note X on which it is based.
Based on our examination of the evidence supporting the assumptions the assumptions, nothing has come to our
attention which causes us to believe that these assumptions do not provide a reasonable basis for the forecast.
Further, in our opinion the forecast is properly prepared on the basis of the assumptions and is presented in
accordance with Philippine Financial Reporting Standards.
Actual results are likely to be different from the forecast since anticipated events frequently do not occur as expected
and the variation may be material.
Example of an unmodified report on a projection
We have learned the projection (include name of the entity, the period covered by the forecast and provide suitable
identification, such as by reference to page numbers or by identifying the individual statements) in accordance with
Philippine Standard on Assurance Engagements applicable to the examination of prospective financial information.
Management is responsible for the projection including the assumptions set out in Note X on which it is based.
This projection has been prepared for (describe purpose). As the entity is in a start-up phase the projection has been
prepared using a set of assumptions that include hypothetical assumptions about future events and management’s
actions that are not necessarily expected to occur. Consequently, readers are cautioned that this projection may not
be appropriate for purposes other than that described above.
Based on our examination of the evidence supporting the assumptions, nothing has come to our attention which
causes us t believe that these assumptions do not provide a reasonable basis for the projection, assuming that (state
or refer to the hypothetical assumptions). Further, in our opinion the projection is properly prepared on the basis of
the assumptions and is presented in accordance with Philippine Financial Reporting Standards.
Even if the events anticipated under the hypothetical assumptions described above occur, actual results are still
likely to be different from the projection since other anticipated events frequently do not occur as expected and the
variation may be material.

When the auditor believes that the presentation and disclosure of the prospective information is
not adequate, the auditor should express a qualified or adverse opinion or withdraw from the
engagement as appropriate.

When the auditor believes that one or more significant assumptions do not provide a reasonable
basis for the prospective financial information, the auditor should either express an adverse
opinion or withdraw from the engagement as appropriate.

When the examination is affected by conditions that preclude application of one or more
procedures considered necessary in the circumstances, the auditor should either withdraw from
the engagement or disclaim the opinion describe the scope limitation in the report on the
prospective financial information.

CODE OF PROFESSIONAL ETHICS FOR CPAs
Code of Ethics for Professional Accountants in the Philippines



is based on the International Code of Ethics for professional accountants developed by the
International Federation of Accountants.
Is mandatory for all CPAs and is applicable to professional services performed in the
Philippines on or after January 1, 2004.
Is divided into three parts:
Part A - applies to all professional accountants unless otherwise specified
Part B applies only to those professional accountants in public practice
Part C applies to employed professional accountants, and may also apply, in
appropriate circumstances, to accountants employed in public practice
CPAs should observe the following FUNDAMENTAL PRINCIPLES:
1. Integrity
2. Objectivity
3. Professional competence and due care
4. Confidentiality
5. Professional behavior
6. Technical standards
RULES APPLICABLE TO ALL PROFESSIONAL ACCOUNTANTS
1. INTEGRITY AND OBJECTIVITY
a.
Integrity implies not merely honesty but fair dealing and truthfulness. The principle
of objectivity imposes the obligation on all professional accountants to be fair,
intellectually honest, and free of conflicts of interest.
b.
Professional accountants should neither accept nor offer gifts or entertainment
which might reasonably be believed to have a significant and improper influence on
their professional judgment or those with whom they deal.
2. PROFESSIONAL COMPETENCE may be divided into two separate phases
a. Attainment of professional competence- requires initially a high standard of general
education followed by specific education, training, and examination in professionally
relevant subjects and a period of work experience.
b. Maintenance of professional competence– requires a continuing awareness of
development in the accountancy profession including relevant national and
international pronouncements on accounting, auditing, and other relevant regulations
and statutory requirements
3. CONFIDENTIALITY
a. Professional accountants have an obligation to respect the confidentiality of information
about a client’s or employer’s affairs acquired in the course of professional services.
b. The duty of confidentiality continues even after the end of the relationship between the
professional accountant and the client or employer.
4. TAX PRACTICE
a. The professional accountant should ensure that the client or the employer are aware of
the limitations attaching to tax advice and services so that they do not misinterpret an
expression of opinion as an assertion of fact.
b. A professional accountant should not be associated with any return or communication
in which there is reason to believe that it:
1. Contains a false or misleading statement;
58
2. Contains statements or information furnished recklessly or without any real
knowledge of whether they are true or false; or
3. Omits or obscure information required to be submitted and such omission or
obscurity would mislead the revenue authorities.
c. When a professional accountant learns of a material error or omission in a tax return of
a prior year, or the failure to file a required tax return, he/she has a responsibility to:
1. Promptly advise the client or employer of the error or omission and recommend
that disclosure be made to the revenue authorities.
2. If the client or employer does not correct the error, he/she:
a. Should inform the client or the employer that it is possible to act for them in
connection with that return or other related information submitted to the
authorities; and
b. Should consider whether continued association with the client or employer in
any capacity is consistent with professional responsibilities.
5. CROSS BORDER ACTIVITIES
When a professional accountant performs services in a country other than the home
country and differences on specific matters exist between ethical requirements of the two
countries, the following provisions should be applied:
1. When the ethical requirements of the country in which the services are being
performed are LESS STRICT than the Philippine Code of Ethics, then our code should be
applied.
2. When the ethical requirements of the country in which the services are being
performed are STRICTER than our code, then the ethical requirements in the country
where services are being performed should be applied.
3. When the ethical requirements of the Philippines are mandatory for services performed
outside the Philippines and are stricter than that set out in (1) and (2) above, then the
ethical requirements of the Philippines should be applied.
6. PUBLICITY
In the marketing and promotion of themselves and their work, professional accountants
should:
a. Not use means which brings the profession into disrepute.
b. Not make exaggerated claims for the services they are able to offer, the qualifications
they possess, or experience they have gained; and
c. Not denigrate the work of other accountants.
RULES APPLICABLE TO PROFESSIONAL ACCOUNTANTS IN PUBLIC PRACTICE

significant that a reasonable and informed third party, having knowledge of all
relevant information, including safeguards applied, would reasonably conclude a
firms, or a member of the assurance team’s integrity, objectivity or professional
skepticism had been compromised.
b. Members of assurance teams, firms, and network firms should identify THREATS to
independence, evaluate the significance of those threats, and, if the threats are other
than clearly insignificant, identify and apply SAFEGUARDS to eliminate the threats or
reduce them to acceptable level, such that independence of mind and independence in
59
appearance are not compromised. In situations when no safeguards are available to
reduce the threat to an acceptable level. The only possible actions are to:
1. Eliminate the activities or interest creating the threat; or

exercising professional skepticism by threats, actual or perceived, from the directors, officers or
employees of an assurance client
SAFEGUARDS
1. When the threats are identified, other than those that are clearly insignificant, appropriate
safeguards should be identified and applied to eliminate the threats or reduce them to an
acceptable level. This decision should be documented
2. When the safeguards are available are insufficient to eliminate the threats to independence or
to reduce them to an acceptable level, or when a firm chooses not to eliminate the activities or
interest creating the threat, the only course of action available will be the refusal to perform, or
withdrawal from, the assurance engagement
