(ISA 320) Materiality in Planning and Performing Audit
1. Introduction:
Scope:
This ISA deals with auditor’s responsibility to apply concept of materiality in planning and performing audit.
Concept of Materiality:
Generally, the concept of materiality in financial reporting framework, if not stated otherwise, is as follows:
o Misstatements and omissions in financial statements are considered material, if they are reasonably expected to influence economic decision of
user, taken on basis of financial statements
o In making judgment about materiality following factors are also considered:
→ Surrounding circumstances
→ Size or nature of misstatement
Auditor determines materiality on basis of professional judgment. This judgment is influenced by auditor’s perception about the information needs of user of
financial statements. In making this perception about user needs auditor is entitled to assume following:
o Users have a reasonable knowledge of business and are willing to study the information in the financial statements diligently
o Users understand that financial statements are prepared and audited to levels of materiality
o Users recognize the uncertainties inherent in certain amounts in the financial statements (such as provisions)
o Users make reasonable economic decisions based on the information in the financial statements.
Concept of materiality shall be applied by auditor at following points:
o Planning and performing audit
o Evaluating effect of identified and uncorrected misstatements
o Forming opinion in auditor’s report
At planning stage auditor will make judgment about materiality level. This judgment will provide basis of following:
o Determining nature timing and extent of risk assessment procedures
o Identifying and assessing risk of material misstatement
o Determining nature timing and extent of audit procedures
2. Objective:
The objective of auditor is to apply the concept of materiality in planning and performing audit.
3. Definitions:
Performance Materiality It means amount set by auditor at a level less than the amount which has been considered material at financial
statement level. This will help to ensure that aggregate of all misstatements will not exceed that materiality level set for
financial statements.
4. Requirements:
i. Determine Materiality and Performance Materiality at Planning stage:
While establishing over all audit strategy, auditor shall determine
o materiality level for financial statement as a whole
o materiality level for class of transaction, account balance or disclosure (if in auditor’s judgment a lower amount is expected to influence
economic decision of user)
o performance materiality
ii. Revise materiality as audit progresses:

Page 2
Auditor must revise materiality level for financial statement as a whole, for class of transaction, account balance or disclosure and performance
materiality if he becomes aware of information which would have caused him to set different levels, had that information been known to him
iii. Documentation:
Auditor shall include in documentation following amounts and factors considered in determining these amounts:
o Materiality for financial statements as a whole
o If applicable, Materiality level for classes of transaction, account balances or disclosures
o Performance materiality
o Any revisions made in above materiality levels

The objective of auditor is to design and perform audit procedures in such a way which enable him to obtain sufficient appropriate audit evidence. This
evidence will be used to draw reasonable conclusion on which audit opinion will be based.
3. Definitions:
Appropriateness of Audit Evidence This is the measure of quality of audit evidence.
This means its relevance and reliability in providing support for conclusions on which audit opinion
will be based.
Audit Evidence Information used by auditor in arriving at conclusion on which audit opinion is to be based.
It includes information contained in accounting records and other information.
Management’s Expert An individual or organization possessing expertise in a field other than accounting and auditing and
whose work is used by entity in preparing financial statements.
Sufficiency of Audit Evidence This is the measure of quantity of audit evidence.
The quantity of audit evidence needed will be effected by:
o auditor's assessment of risk of material misstatement &
o quality of audit evidence
4. Requirements:
i. Sufficient Appropriate Audit Evidence:
Auditor shall design audit procedures to obtain sufficient appropriate audit evidence
Audit evidence comprises of information that;
o Supports and corroborates management assertions &
o Contradicts management assertions
Absence of information is also used by auditor as audit evidence e.g., management’s refusal to provide requested representation
will constitute audit evidence
Sufficiency and appropriateness of audit evidence are interrelated. Sufficiency is measure of quantity and quantity of evidence
needed is effected by auditor’s risk assessment (if assessed risk is high more evidence will be required) and its quality (in case of
high quality of evidence, lesser quantity may be required). Obtaining more evidence may not compensate for its poor quality.
Sources of audit evidence:
o Audit procedures
o Consistent audit evidence from different sources or from items of different nature
o Information from sources independent of entity e.g., third party confirmations
Audit procedures to obtain audit evidence:
o Inspection involves examining records or documents and physical examination of an asset e.g., while testing
controls, the inspection of records for authorization
o Observation consists of looking at a process being performed by others e.g., auditor’s observation of inventory
counting by entity’s personnel
o External confirmation represents audit evidence obtained by auditor as direct written response to auditor from

Page 2
third party.
o Recalculation consists of checking mathematical accuracy of documents or records.
o Reperformance means auditor’s independent execution of a procedure which was originally performed by entity’s
internal controls
o Analytical Procedures consists of evaluation of financial information through analysis of plausible relationship
among financial and non financial data
o Inquiry is seeking information of knowledgeable persons, inside and outside entity
ii. Information to be used as Audit Evidence:
Auditor shall consider relevance and reliability of information to be used as audit evidence
Quality of audit evidence is effected by relevance and reliability of information on which it is based.
Relevance:
Relevance deals with logical connection with purpose of audit procedure
Reliability:
Reliability of audit evidence is dependent upon its source, nature and circumstances in which it has been obtained. Following
shall be considered in determining reliability of audit evidence:
o Source:
Evidence from independent source, outside entity is more reliable
If internal controls are effective, then internally generated evidence is more reliable
Audit evidence obtained directly by auditor is more reliable then those obtained indirectly
o Nature:
Evidence in document form is more reliable then oral
Evidence from original document is more reliable then from photocopy or facsimiles
If information to be used as audit evidence was prepared by management’s expert, then auditor shall do following:
o Evaluate competence, capabilities and objectivity of expert
o Obtain understanding of work of expert
o Evaluate appropriateness of work of expert for relevant assertion
Nature, timing and extent of audit procedures to evaluate work of management expert shall be effected by following:
o Nature & complexity of matter
o Risk of material misstatement in the matter
o Availability of alternate source of audit evidence
o Nature scope and objective of expert’s work
o Whether management expert is employed or is engaged to provide such services
o Extent of management’s control over expert work
o Internal controls over expert’s work
o Auditor’s knowledge about expert’s field of expertise
o Auditor’s past experience of work of expert
Sources of information about competence and capabilities of expert:
o Personal experience with work of expert
o Discussion with expert
o Discussion with others who are familiar with work of expert
o Knowledge of expert’s qualification, licence to practice, professional membership etc
o Books or papers published by expert
When information produced by entity is to be used by auditor as audit evidence then auditor will do following:
o Evaluate whether information is reliable
o Obtain audit evidence about accuracy and completeness of information

Page 3
o Evaluate whether information is sufficiently precise and detailed for audit purposes
iii. Selecting items for testing to obtain Audit Evidence:
While designing audit procedures auditor shall determine how to select items for testing so that the purpose of audit procedure could be achieved.
Audit can select items for testing in any of following ways:
a. Selecting all items (100% testing)
b. Selecting specific items
c. Audit Sampling
a. Selecting all items (100% testing):
Selecting all items is appropriate in following circumstances:
o Population consists of small number of large value items
o There is a risk that other means will not provide other sufficient appropriate audit evidence
o Repetitive calculation or automatic processing by information system makes 100% examination cost effective
b. Selecting specific items:
Following factors are relevant in selecting specific items:
o Understanding of entity
o Assessed risk of material misstatement
o Characteristics of population being tested
Specific items selected may include following:
o High value or key items
For example items that have a history of errors, risk prone, unusual or suspicious
o All items over a certain amount
Auditor may decide to examine all items over a certain amount so that a large amount of total population could be
tested.
o Items to obtain information
To obtain information such nature of entity or nature of transaction.
c. Audit Sampling:
Will be discussed in ISA 530
iv. Inconsistencies in or doubts over Audit Evidence:
If
o Audit evidence obtained from one source is inconsistent with that from another source OR
o Auditor has doubts over reliability of information used as audit evidence
Then auditor shall
o consider modify the audit procedures to resolve the matter &
o consider effect of matter on other aspects of audit

Page 1
(ISA 520) Analytical Procedures
1. Introduction:
Scope:
This ISA deals with
o auditor’s use of substantive procedures as audit procedures (substantive analytical procedures) &
o auditor’s responsibility to perform analytical procedures near end of audit, to assist auditor in forming overall conclusion on financial statements
2. Objective:
The objectives of auditor are following:
o Obtain relevant and reliable audit evidence when using substantive analytical procedures
o Design and perform analytical procedures near end of audit that will assist auditor in forming overall conclusion as to whether financial
statements are consistent with auditor’s understanding of entity.
3. Definitions:
Analytical Procedures Means evaluation of financial information through analysis of plausible relationship among financial and non financial data.
It also includes investigation of fluctuations that are inconsistent with other information
Analytical procedures include:
Comparison of financial information with;
o Prior periods
o Anticipated results of entity, such as budgets or forecasts or expectations of auditor
o Similar industry information such as comparison of ratio of sales to debtors with industry average
Consideration of relationships;
o Among elements of financial information such as gross profit ratio
o Between financial information and non financial information such as payroll cost to number of employees
4. Requirements:
i. Substantive Analytical Procedures:
While designing and performing substantive analytical procedures, auditor shall do following:
o Determine suitability of substantive analytical procedure for given assertion
o Evaluate reliability of data from which auditor has developed expectation of recorded amounts. Reliability of data shall depend on following
factors
→ Source e.g., information will be more reliable if obtained from independent source outside entity
→ Comparability e.g., broad industry data need to be supplemented to make it comparable to entity
→ Nature and Relevance e.g., where budget has been prepared on basis of expected results rather than targets to be achieved
→ Controls over preparation
o Develop expectation of recorded amounts and evaluate whether expectation is sufficiently precise to identify misstatements
o Determine amount of difference, between expected amounts and actual amounts, which will not require further investigation and hence
will be acceptable
ii. Analytical Procedures that assist when forming an overall conclusion:
Auditor shall design and perform analytical procedures near end of audit that will assist auditor in forming overall conclusion as to whether financial
statements are consistent with auditor’s understanding of entity.
iii. Investigating results of Analytical Procedures:
If inconsistent fluctuations are identified then auditor will investigate differences in following ways:
o Inquiry of management and obtain appropriate audit evidence of management’s response
o Perform other audit procedures that are necessary in circumstances

Page 1
(ISA 530) Audit Sampling
1. Introduction:
Scope:
This ISA applies when auditor has decided to use audit sampling in performing audit procedures.
2. Objective:
While using audit sampling, the objective of auditor is to provide reasonable basis to draw conclusions about population from which sample is selected.
3. Definitions:
Audit Sampling Application of audit procedures to less than 100% of items of population in such a way that all sampling units have a
chance of selection.
Population Entire set of data from which sample is selected and about which auditor wishes to draw conclusions
Sampling Risk It is the risk that auditor’s conclusion based on sample may be different from conclusion if entire population were tested.
Sampling risk can lead to following two types of erroneous conclusions:
o For tests of controls – that controls are more effective than they actually are and for tests of details – that a
material misstatement does not exist when in fact it does.
o For tests of controls – that controls are less effective than they actually are and for tests of details – that a
material misstatement exists when in fact it does not.
Non Sampling Risk The risk that auditor will reach erroneous opinion for any reason not related to sampling risk
Anomaly A misstatement or deviation which is not representative of misstatement or deviation in population.
Sampling Unit The individual item constituting population.
Statistical Sampling A sampling approach that has following characteristics:
o Random selection of sample items
o Use of probability theory to evaluate sample results
Non Statistical Sampling Sampling approach that does not have characteristics of Statistical Sampling
Stratification Dividing population into sub-populations having similar characteristics.
Tolerable Misstatement Monetary amount set by auditor, in respect of which auditor wants to obtain an assurance that actual misstatement in
population does not exceed monetary amount set by auditor.
Tolerable Rate of
Deviation
Rate of deviation from internal controls set by auditor, in respect of which auditor wants to obtain assurance that actual
rate of deviation in population does exceed the rate of deviation set by auditor.
Advantages of statistical sampling:
o It provides an objective, mathematically precise basis for the sampling process.
o Sample size can be calculated precisely (using statistical probability techniques).
o There may be circumstances where statistical sampling is the only means of auditing efficiently (for example,
in the case of very large ‘populations’ of items).
Disadvantages of statistical sampling:
o Training and technical expertise is required to use sampling techniques effectively.
o This may require an investment in the necessary training for audit staff.
o Sample sizes may be larger than under a judgmental approach, thus increasing the time (and the cost)
involved in the audit.
o There may be circumstances where judgmental sampling would be better.

Page 2
4. Requirements:
i. Sample Design, Size and Selection of Items for Testing:
Sample Design:
While designing the sample, auditor is required to:
o consider the purpose of the audit procedure and the population from which the sample will be drawn
o determine a sample size sufficient to reduce sampling risk to an acceptably low level
o select items for the sample in such a way that each sampling unit in the population has an equal chance of selection
Sample Size:
Auditor shall determine sample size sufficient to reduce sampling risk to acceptable low level. The determination of sample size will depend on
following factors:
o sampling approach to be used (statistical or non-statistical)
o characteristics of the population from which the sample is to be drawn
o sample selection method
o what constitutes a misstatement or deviation
o ‘tolerable’ misstatement or rate of deviation
o ‘expected’ misstatement or rate of deviation.
Selection of Items for Testing:
Selection should be made in such a way that each sampling unit has a chance of selection. Following methods may be used for selection:
o Random Selection: All items in the population have an equal chance of selection. This is typically achieved by the use of random
numbers tables.
o Systematic Selection: The number of sampling units in population is divided by sample size to give a sampling interval. With
systematic sampling, a random starting point is chosen from the population and then items are selected with a standard gap between them
for example, every 50th item
o Haphazard Selection: The auditor selects sample without following structured techniques, for example, choosing any 100 invoices from
a file.
o Block Selection: This involves selection of a block of items from population.
ii. Performing Audit Procedures:
o Auditor shall perform audit procedures on each item selected
o If the audit procedure is not applicable to the selected item, the auditor must perform the procedure on a replacement item.
o If the auditor is unable to apply the procedure (or a suitable alterative), that item must be treated as a misstatement or deviation.
iii. Nature and Cause of Deviations and Misstatements:
o The auditor shall investigate the nature and cause of any misstatements or deviations and evaluate their possible effect
o If the auditor considers the misstatement or deviation to be an anomaly he must obtain a high degree of certainty about this and perform
additional audit procedures to obtain sufficient evidence that the misstatement or deviation does not affect the rest of the population.
iv. Projecting Misstatements:
For tests of details auditor will project the misstatements found in the sample to the entire population
For tests of details, auditor will use the sample results to estimate the likely misstatement that exists in the population by
extrapolating the error found in the sample over the population.
For tests of controls, the sample deviation rate will be the projected deviation rate for the population. An unexpectedly high
sample deviation rate may cause the auditor to review the assessed risk of misstatement and therefore increase the extent of
tests of detail to be performed.
v. Evaluating Results of Audit Sampling:
The auditor shall evaluate:
o the results of the sample
o whether the use of audit sampling has provided a reasonable basis for conclusions about the population. If auditor concludes that it does
not provide reasonable basis for conclusion then the auditor will need to consider carrying out additional audit procedures.

(ISA 550) Related Parties
1. Introduction:
Scope:
This ISA deals with auditor’s responsibility relating to related party relationships and related party transactions in an audit of financial statements.
Nature of Related Party & Related Party Transactions:
Related party transactions can exist in normal course of business. In such situation, there may not be a high risk of material misstatement. However, in
following circumstances, related party transactions can pose high risk of material misstatement:
o Related party operated through complex relationships
o Information system is ineffective in identifying related parties and transactions with related parties
o Related party transactions are not conducted under normal market terms and conditions
Responsibilities of Auditor:
o Obtain understanding of related party relationships and transactions. This understanding must be sufficient for the auditor to:
→ recognize fraud risk factors arising from related party relationships and transactions
→ conclude whether the financial statements achieve fair presentation in respect of related party relationships and transactions.
o Obtain sufficient appropriate audit evidence that whether related party relationships and transactions have been appropriately identified,
accounted for and disclosed.
o Plan and perform audit with professional skepticism
2. Objective:
Objective of auditor is to:
o Obtain understanding of related party relationships and transactions
o Obtain sufficient appropriate audit evidence that whether related party relationships and transactions have been appropriately identified,
accounted for and disclosed
3. Definitions:
Arm’s Length Transactions Transaction between willing buyer and willing seller who are unrelated and are acting independently of each other and
are pursuing their best interest.
Related Party A party which is:
o A related party as defined in financial reporting framework OR
o If financial reporting framework does not establish related party requirements, then
→ Person or entity that has significant influence on reporting entity
→ Entity over which reporting entity has significant control
→ Entity that is under common control with reporting entity and another entity
4. Requirements:
i. Risk Assessment Procedures:
Following procedures shall be performed to identify risk of material misstatement associated with related parties:
a) Understanding entity’s related party relationships and transactions:
During risk assessment process, auditor shall perform following procedures to obtain understanding of related party relationships and
transactions:
o Consider the risk of material misstatement due to fraud or error arising from related party relationships and transactions.
o Make inquiries of management in respect of:
→ the identity of related parties
→ the nature of relationships with those related parties
→ the nature of transactions entered into with related parties
o Obtain an understanding of the internal controls over:
→ the identification of, accounting for and disclosure of related party relationships and transactions
→ the authorisation and approval of significant related party transactions
→ the authorisation and approval of significant transactions outside the normal course of business.

Page 2
Obtain a list of related parties from management and ensure its completeness through following procedures:
o Review working papers for previous years, to look for known related parties.
o Review the company’s procedures for identifying related parties.
o Inquire about relationships between directors and other entities (for example, does any director own another
company, and have there been any transactions between that company and the client?)
o Review shareholder records for the names of major shareholders.
o Review minutes of shareholder meetings (general meetings)
o Ask any other audit firms involved in the audit about related parties (if the audit is the audit of a group of
companies and more than one firm of auditors is involved). Or ask previous auditors of the company about their
knowledge of related parties
b) Alertness towards related party information while reviewing records:
Auditor should remain alert, while inspecting records, for information that may be helpful in identifying related party relationships or
transactions. Auditor is required to inspect following :
o bank and legal confirmations obtained as part of audit work.
o Minutes of shareholder and management meetings
o Any other records or documents the auditor considers necessary
c) Share related party information with engagement team:
Auditor should share with engagement team, relevant related party information
ii. Indentify and Assess Risk of Material Misstatement Associated with Related Party and Related Party Transactions:
Auditor shall comply with requirements of ISA 315 and ISA 240.
iii. Responses to Identified Risks:
a) Identification of previously unidentified related parties and transactions with related parties:
In such circumstance, auditor shall do following:
o Determine whether the underlying circumstances confirm the existence of those relationships or transactions.
o Communicate the relevant information to the audit team.
o Request management to identify all transactions with the newly identified related parties.
o Inquire as to why the entity’s system failed to identify or disclose these related party relationships or transactions.
o Perform appropriate substantive procedures on the newly identified related parties or significant related party transactions.
o Reconsider the risk of there being unidentified or undisclosed related parties or (significant) related party transactions and
perform additional procedures as necessary.
o If the non-disclosure appears intentional, evaluate the implications for the audit.
b) Identified related party transactions outside normal course of business:
In such circumstance, auditor shall do following:
o Inspect the underlying contracts or agreements to evaluate whether:
→ the contracts etc. were entered into in order to engage in fraudulent financial reporting or to hide the misappropriation
of assets (a lack of business rationale might indicate this)
→ the terms of the contracts etc. are consistent with management’s explanations
→ the transactions have been properly accounted for and disclosed.
o Obtain evidence that the transactions were properly authorised.
c) Assertion that related party transactions were conducted at arm’s length:
If management has made a statement in the notes to the financial statements that a related party transaction was made on the same terms as an
arm’s length transaction, the auditor must obtain evidence to support this assertion.
iv. Evaluation of Identified Related Party Relationships and Transactions:
Auditor shall evaluate following:
o Whether identified related party relationships and transactions have been appropriately accounted for and disclosed
o Whether effect of related party relationship and transactions;
→ Prevent financial statements from achieving fair presentation OR
→ Cause financial statements to be misleading

(ISA 560) Subsequent Events
1. Introduction:
Scope:
This ISA deals with auditor’s responsibility relating to subsequent events in an audit of financial statements.
Subsequent Events:
While referring to subsequent events, financial reporting framework usually refers to two types of events:
o Those that provide evidence of condition that existed at date of financial statements
o Those that provide evidence of condition that arose after date of financial statements
2. Objective:
Objective of auditor is to:
o obtain sufficient, appropriate evidence about whether events occurring between the date of the financial statements and the date of the audit
report are appropriately reflected in financial statements.
o respond appropriately to facts that become known to him after the date of the audit report which if were known to him at date of audit report,
may have caused him to amend his report.
3. Definitions:
Date of Financial Statements Date of end of latest period covered by Financial Statements.
Date of approval of Financial Statements Date when Financial Statements have been prepared and approved by recognized authority.
The date mentioned on Auditor’s Report in accordance with ISA 700.
Date of issue of Financial Statements The date on which auditor’s report and financial statements are made available to third parties.
Subsequent Events Subsequent Events are:
o Events occurring between date of financial statements and date of auditor’s reports and
o Facts that become known to auditor after auditor’s report
4. Requirements:
i. Events between Date of Financial Statements & Date of Auditor’s Report:
Auditor shall obtain sufficient appropriate audit evidence that subsequent events requiring adjustment or disclosure in financial statements have been
identified and reported in financial statements. During normal audit procedures auditor can find evidence of subsequent events and in this situation
additional procedures are not required. Such normal audit procedures may include following:
Normal Audit Verification Procedures:
Receivables: consider whether receivables at the end of the reporting period are collectable. Cash receipts after the year-end may
indicate a significant non-payment, suggesting the need to write off a debt as irrecoverable
Inventories: Review the net realisable value of inventory. Sales of inventory after the year-end may indicate that some inventory in the
balance sheet is over-valued because NRV was less than its cost.
Unrecorded Liabilities: Review invoices received after the reporting period but relating to the period covered by the financial statements
Dishonoured Cheques: A review of the entity’s cash position at the end of the reporting period may find that a cheque from a customer, recorded
as part of the bank balances, was dishonoured after the reporting period
Audit Procedures for Identifying Subsequent Events:
o obtain an understanding of management’s procedures for identifying subsequent events
o inquire of management as to whether any subsequent events have occurred which might affect the financial statements
o read the entity’s latest subsequent financial statements

Page 2
o read minutes of shareholders’ meetings, meetings of the board of directors and senior management meetings held after the date of the financial
statements and inquire about matters discussed at any such meetings where minutes are not yet available
o obtain written representations in respect of subsequent events.
Written Representations:
Obtain written representation from management and TCWG, that subsequent events have been accounted for and disclosed in financial statements in
accordance with requirements of financial reporting framework.
ii. Facts Discovered after date of Auditor’s Report but before Date of Issue of Financial Statements:
Auditor has no obligation to perform audit procedures after date of audit report. His liability is limited only to the facts he becomes aware of after
issuing audit report.
if he becomes aware of a fact which if were known to him at the date of his report, may have caused him to amend his report then following should be
done:
o discuss the matter with management
o determine whether the financial statements need amending
o inquire how management intend to address the matter in the financial statements
If the financial statements are amended, the auditor shall do following:
o carry out the necessary audit procedures on the amendment
o extend his review of subsequent events up to the date of the new audit report
If financial statements are not amended by management and auditor feels that an amendment is necessary then following should be done:
o If the audit report has not yet been provided to the entity, modify his opinion as appropriate
o If the audit report has been provided to the entity:
→ instruct management not to issue the financial statements before the necessary amendments have been made
→ if even then management issues financial statements, then take appropriate action to prevent reliance on the audit report, after
taking legal advice.
iii. Facts Discovered after Financial Statements have been Issued:
Auditor has no obligation to perform any audit procedures after financial statements have been issued. However, if he becomes aware of a fact, which if
were known to him at date of audit report, may have caused him to amend his report, then following steps must be taken by auditor:
o determine whether the financial statements need amendment
o inquire how management intend to address the matter in the financial statements
If the financial statements are amended, then:
o carry out the necessary audit procedures on the amendment
o review the steps taken by management to inform anyone who received the original financial statements and audit report
o extend his review of subsequent events up to the date of the new audit report
o issue a new audit report, containing an emphasis of matter paragraph. This should refer to a note in the revised financial statements that
explains in more detail the reason for the re-issue of the financial statements
If financial statements are not amended and auditor feels that an amendment is necessary then following should be done:
o take appropriate action to prevent reliance on the audit report, after taking legal advice

Page 1
(ISA 580) Written Representations
1. Introduction:
Scope:
This ISA deals with auditor’s responsibility to obtain written representation from management or from TCWG in an audit of financial statements.
Written Representation as Audit Evidence:
Written representation is used as audit evidence in response to auditor’s inquiries.
Written representations provide necessary audit evidence in various cases; however, it is quite possible that they do not provide sufficient appropriate audit
evidence on their own about the matter.
If management does not provide the requested written representations, it may alert the auditor to the possibility that any significant issues may exist.
Representation could be oral or written. A request for written representation, rather than oral representation, may prompt management to consider such
matters more rigorously. This will ultimately enhance the quality of the representation.
2. Objective:
Objective of auditor is:
o to obtain written representations from management and TCWG that
→ they have fulfilled their responsibility for the preparation of the financial statements
→ the information provided to the auditor is complete
o to support other audit evidence or specific assertions in the financial statements by means of written representations
o to respond appropriately when
→ written representations is provided, or
→ if requested representation is not provided to the auditor
3. Definitions:
Written Representation A written statement by management provided to the auditor to confirm certain matters or to support other audit evidence.
Written representations do not include:
o financial statements
o assertions in financial statements
o supporting books and records
4. Requirements:
i. Management from whom Written Representations Requested:
Auditor must always request for representation from management with appropriate responsibility for financial statements and having knowledge of
the matters concerned.
In some cases management may make inquiries of others who have specialized knowledge relating to a matter.
Such individuals may include:
o An actuary responsible for actuarially determined accounting measurements.
o Staff engineers who may have responsibility for and specialized knowledge about environmental
liability measurements.
o Legal Advisor, who may provide information essential to provisions for legal claims.
ii. Written Representations about Management’s Responsibilities:
In these representations management acknowledges that:
o it has fulfilled its responsibility for the preparation and fair presentation of financial statements in accordance with the applicable financial
reporting framework
o it has provided the auditor with all relevant information
o all transactions have been recorded and are reflected in the financial statements.

Page 2
iii. Other Written Representations:
Other ISAs may also require the auditor to request written representations. In such situation, the auditor shall request such other written
representations.
iv. Date of and Period Covered by Written Representation:
The date of the written representations shall be as near as practicable to, but not after, the date of the auditor’s report on the financial statements.
The written representations shall be for all financial statements and period(s) referred to in the auditor’s report.
v. Form of Written Representations:
The written representations shall be in the form of a representation letter addressed to the auditor. [Pg 255-256 of Study Text]
vi. Written Representation provided by Management is Doubtful OR is not provided by Management:
Doubtful Representations:
If the auditor has doubts about the competence, integrity, ethical values or diligence of management, the auditor shall determine the effect on
reliability of representations and audit evidence in general.
If written representations are inconsistent with other audit evidence, the auditor shall:
o perform audit procedures to resolve the matter
→ If the matter remains unresolved, the auditor shall reconsider the assessment of the competence, integrity, ethical values or
diligence of management
o determine the effect that this may have on the reliability of representations (oral or written) and audit evidence in general
If the auditor concludes that the written representations are not reliable, the auditor shall determining the possible effect on the opinion in the
auditor’s report in accordance with ISA 705
Written Representation Refused:
If management refuses to provide requested written representations the auditor is required to:
o re-evaluate the integrity of management and reconsider the impact on other representations and audit evidence
o take appropriate action, including considering the effect on the audit report

(ISA 610-Revised) Using Work of Internal Auditors
1. Introduction:
Scope:
This ISA deals with external auditor’s responsibility in following situations:
o Using work of internal audit in obtaining audit evidence
o Obtaining direct assistance from internal audit
This ISA does not apply if entity does not have an internal audit function.
If entity has internal audit function, then this ISA will not apply if:
o Work of internal audit is not relevant to audit
o External auditor, based on initial understanding of entity, does not intend to use work of internal audit
Nothing in this standard require auditor to reduce nature, timing and extent of audit procedures
Relationship between ISA 315 (Revised) and ISA 610 (Revised):
The objectives of the internal audit function are determined by management and TCWG. While the objectives of the internal audit function and the external
auditor are different. Some of the ways in which the internal audit function and the external auditor achieve their objectives may be similar.
While obtaining understanding of entity, auditor shall determine that whether:
o Work of internal audit is to be used for obtaining audit evidence
o Auditor can obtain direct assistance from internal audit
o Work of internal audit is relevant for external auditor
o External auditor intend to use the work of internal audit
This understanding will affect the nature, timing and extent of audit procedures to be applied by external auditor
External Auditor’s Responsibility for Audit:
The external auditor has sole responsibility for the audit opinion, and that responsibility is not reduced by the external auditor’s use of the work of the
internal auditor.
This ISA provides guidance on following:
o conditions that are necessary for the external auditor, to be able to use the work of internal auditors
o necessary effort to obtain sufficient appropriate evidence that the work of the internal auditor is adequate for external audit
o provide a framework to prevent over or undue use of work of internal audit
2. Objective:
Objectives of auditor are:
o To determine whether to use the work of internal auditor or to use direct assistance from internal auditor
o If using the work of internal auditor, then, to determine whether that work is adequate for the external auditor’s purposes
o If using direct assistance from internal auditor, then, to appropriately direct, supervise and review his work
3. Definitions:
Internal Audit Function A function of an entity that performs assurance and consulting activity to evaluate and improve effectiveness
o Governance
o Risk management
o Internal controls
Direct Assistance Use of internal auditor to perform audit procedures under direction, supervision and review of external auditor.
4. Requirements:
i. Determine whether work of internal audit can be used, in which areas work can be used and to what extent work of internal
audit can be used:
Whether work of internal audit can be used?

Page 2
The external auditor shall determine whether the work of the internal audit function can be used for purposes of the audit by
evaluating the following:
o The extent to which organizational status of internal audit and relevant policies and procedures support the objectivity of
the internal audit
o The level of competence of the internal audit function
o Whether the internal audit function applies a systematic and disciplined approach, including quality control
The external auditor shall not use the work of the internal audit function if the external auditor determines that
o The function’s organizational status and relevant policies and procedures do not adequately support the objectivity of
internal auditors
o The function lacks sufficient competence
o The function does not apply a systematic and disciplined approach, including quality control
Areas where work of internal audit can be used and the extent to which such work can be used:
As a basis for determining the areas and the extent to which the work of the internal audit function can be used, the external auditor
shall consider
o nature and scope of the work that has been performed by the internal audit function
o its relevance to the external auditor’s overall audit strategy and audit plan
The external auditor shall prevent undue use of the work of the internal audit function and shall plan to use less of the work of the
function and perform more of the work directly in following situations:
o The more judgment is involved in
→ Planning and performing relevant audit procedures
→ Evaluating the audit evidence gathered
o The higher the assessed risk of material misstatement at the assertion level
o The less the internal audit function’s organizational status and relevant policies and procedures adequately support the
objectivity of the internal auditor
