AUDITING AND
ASSURANCE STANDARDS
|
In order to facilitate understanding of the scope and
authority of the pronouncements of the Auditing and Assurance Standards Board (‘AASB’),
the ICAI has issued revised preface viz., Preface to Standards on Quality
Control, Auditing, Review, Other Assurance and Related Services, which has come
into effect from 1st April, 2008. As per the same the Standards of the following
nature issued by the AASB shall collectively known as the Engagement Standards:
-
Standards on Auditing (SAs), to be applied in the
audit of historical financial information.
-
Standards on Review Engagements (SREs), to be applied
in the review of historical financial information.
-
Standards on Assurance Engagements (SAEs), to be
applied in assurance engagements, dealing with subject matters other than
historical financial information.
-
Standards on Related Services (SRSs), to be applied
to engagements involving application of agreed upon procedures to
information, compilation engagements, and other related services
engagements, as may be specified by the ICAI.
In terms of the same, the existing Auditing and Assurance
Standard (‘AAS’) has been re-numbered and classified in the above four
categories as under:

SA 300 : Planning an audit of
Financial Statements
Scope:
Framed in the
context of recurring audits. Additional considerations in initial audit
engagements are separately identified.
-
Preliminary
Engagement Activities:
-
Performing procedures required by SA 220, Quality
Control for Audit Works regarding the continuance of the client
relationship and the specific audit engagement;
-
Evaluating compliance with ethical requirements; and
-
Establishing an understanding of the terms of the
engagement.
-
Risk assessment procedures as determined under SA
315, Identifying and Assessing the Risks of Material Misstatement
through understanding the Entity and its involvement;
-
Audit procedures determined under SA 330, ‘the
Auditor’s responses to assessed risks’;
-
Other planned audit procedures that are required to
be carried out so that the engagement complies with SAs.
-
Nature, timing and extent of direction and
supervision of engagement team members and the review of their work
-
The Standard recognizes the need to modify the
overall audit strategy and audit plan based on the revised consideration
of assessed risks.
-
Where the auditor decides to discuss elements of
planning with the management, ensure that the effectiveness of the audit
is not compromised say, by making the audit procedures too predictable.
-
The Appendix to the Standard lists examples of
considerations in establishing the overall audit strategy.
-
The audit plan is more detailed than the overall
audit strategy in that it includes the nature, timing and extent of audit
procedures to be performed by engagement team members.
-
Establishing the overall audit strategy for the audit
of a small entity need not be a complex or time-consuming exercise; it
varies according to the size and complexity of the audit, and the size of
the engagement team. For example, a brief memorandum prepared at the
completion of the previous audit, based on a review of the working papers
and highlighting issues identified in the audit just completed, updated in
the current period based on discussions with the owner-manager, can serve
as the documented audit strategy for the current audit engagement, if it
covers the matters noted in paragraph 7 of the Standard.
-
The Standard requires the auditor to document overall
audit strategy and audit plan, including the significant changes made
subsequently therein with reasons thereof.
-
Documentation of Audit strategy could be in the form
of a memorandum that contains key decisions regarding the overall scope,
timing and conduct of the audit.
-
For documentation of Audit plan, the Standard permits
use of standard audit programmes or audit completion checklists, tailored
as needed to reflect the particular engagement circumstances.
Additional Considerations in Initial Audit Engagements:
-
Prior to starting an initial audit the auditor should
perform procedures required by SA 220 regarding the acceptance of the
client relationship and the specific audit engagement and communicate with
the predecessor auditor where there has been a change of auditors.
-
The auditor may consider the following:
-
Unless prohibited by law or regulation,
arrangements to be made with the predecessor auditor, to review the
predecessor auditor’s working papers;
-
Communication with those charged with governance
any major issues discussed with management at the time of initial
selection as auditor;
-
The audit procedures necessary to obtain sufficient
appropriate audit evidence regarding opening balances.
-
Audit strategy: It need not be a complex or
time-consuming exercise; it varies according to the size and complexity of
the audit, and the size of the engagement team. A brief memorandum
prepared at the completion of the previous audit, based on a review of the
working papers and highlighting issues identified in the audit just
completed, updated in the current period based on discussions with the
owner-manager, can serve as the documented audit strategy for the current
audit engagement, if it covers the matters noted in paragraph 7 of the
Standard.
-
When an audit is carried out entirely by a sole
practitioner and a complex or unusual issues are involved, it may be
desirable to consult with other suitably-experienced auditors.
SA 315 : Identifying and Assessing the Risks
of Material Misstatement through understanding the Entity and its Environment
Scope:
It deals with the auditor’s responsibility to identify
and assess the risks of material misstatement in the financial statements,
through understanding the entity and its environment, including the entity’s
internal control. Its objective is in providing a basis for designing and
implementing responses to the assessed risks of material misstatement
thereby assist the auditor to reduce the risk of material misstatement to an
acceptably low level.
Risk Assessment Procedures and Related Activities:
-
Inquiries of management, and of others within the
entity who may have information that is likely to assist in identifying
risks of material misstatement;
-
Analytical procedures;
-
Observation and inspection;
-
Consideration whether information obtained from the
auditor’s client acceptance or continuance process is relevant to
identifying risks of material misstatement;
-
Where the engagement partner has performed other
engagements for the entity, to consider the relevance of the said
information to identifying risks of material misstatement;
-
In addition the auditor may perform other procedures
like reviewing information obtained from external sources such as trade
and economic journals; reports by analysts, banks, or rating agencies; or
regulatory or financial publications or making inquiries of the entity’s
external legal counsel or of valuation experts that the entity has used.
-
When the auditor uses information obtained from his
previous experience with the entity and from audit procedures performed in
previous audits, determine whether changes have occurred since the
previous audit that may affect its relevance to the current audit.
-
The engagement partner and other key engagement team
members to discuss the susceptibility of the material misstatement, and
the application of the applicable financial reporting framework to the
entity’s facts and circumstances.
-
The Standard recognises that it is not always
necessary or practical for the discussion to include all members in a
single discussion nor is it necessary for all of the members of the
engagement team to be informed of all of the decisions reached in the
discussion. The engagement partner may discuss matters with only the key
members of the engagement team while delegating discussion with others.
-
Relevant industry in which the entity operates;
-
The regulatory, and other external factors
including the financial reporting framework, applicable to the entity ;
-
The nature of the entity, including its operations,
ownership and governance structures, investments, investment activities
and financing and financing activities;
-
Selection and application of accounting policies by
the entity, including the reasons for changes, if any thereto. Also to
evaluate if accounting policies are appropriate for its business and
consistent with the applicable financial reporting framework and
accounting policies used in the relevant industry;
-
The entity’s objectives and strategies, and the
related business risks that may result in risks of material
misstatement;
-
The measurement and review of the entity’s
financial performance; i.e., the things the management regards it as
important;
-
The market and competition, including demand,
capacity, and price competition;
-
Cyclical or seasonal activity;
-
Product technology relating to the entity’s
products;
-
Energy supply and cost.
-
Accounting principles and industry specific
practices;
-
Regulatory framework for a regulated industry;
-
Legislation and regulation that significantly
affect the entity’s operations, including direct supervisory activities;
-
Taxation;
-
Government policies currently affecting the conduct
of the entity’s business, such as monetary, including foreign exchange
controls, fiscal, financial incentives (for example, government aid programmes), and tariffs or trade restrictions policies;
-
Environmental requirements affecting the industry
and the entity’s business.
-
The methods the entity uses to account for
significant and unusual transactions;
-
The effect of significant accounting policies in
controversial or emerging areas for which there is a lack of
authoritative guidance or consensus;
-
Changes in the entity’s accounting policies;
-
Financial reporting standards and laws and
regulations that are new to the entity and when and how the entity will
adopt such requirements.
-
Industry developments;
-
New products and services;
-
Expansion of the business;
-
New accounting requirements;
-
Regulatory requirements;
-
Current and prospective financing requirements;
-
Use of IT;
-
The effects of implementing a strategy,
particularly any effects that will lead to new accounting requirements.
Appendix 2 to the Standard provides examples of
conditions and events that may indicate risks of material misstatement.
-
Performance measures, whether external or internal,
create pressures on the entity in turn, may motivate management to take
action to improve the business performance or to misstate the financial
statements. Information used by management for measuring and reviewing
financial performance, and which the auditor may consider, include:
-
Key performance indicators and key ratios, trends
and operating statistics;
-
Period-on-period financial performance analyses;
-
Budgets, forecasts, variance analyses, segment
information and divisional, departmental or other level performance
reports;
-
Employee performance measures and incentive
compensation policies;
-
Comparisons of an entity’s performance with that of
competitors.
Besides, external information such as analysts’ reports
and credit rating agency reports may represent useful information for the
auditor.
-
Examples of other external factors include the
general economic conditions, interest rates and availability of financing,
and inflation or currency revaluation.
-
The understanding establishes a frame of reference
within which the auditor plans the audit and exercises professional
judgment throughout the audit.
Understanding
of Internal control:
-
The auditor shall obtain an understanding of internal
control relevant to the audit. Though it is a matter of the auditor’s
professional judgment whether a control, individually or in combination
with others, is relevant to the audit, the factors to determine relevance
to the audit may include such matters as the following:
-
Materiality;
-
Significance of the related risk;
-
Size of the entity;
-
Nature of the entity’s business, including its
organization and ownership characteristics;
-
Diversity and complexity of the entity’s
operations;
-
Applicable legal and regulatory requirements;
-
Circumstances and the applicable component of
internal control;
-
Nature and complexity of the systems that are part
of the entity’s internal control, including the use of service
organizations;
-
Whether, and how, a specific control, individually
or in combination with others, prevents, or detects and corrects,
material misstatement.
-
Inquiring of entity personnel;
-
Observing the application of specific controls;
-
Inspecting documents and reports;
-
Tracing transactions through the information system
relevant to financial reporting.
It is emphasized that inquiry alone is not sufficient
for such purposes.
-
To provide a useful framework for auditors to
consider how different aspects of an entity’s internal control may affect
the audit, for the purpose of the Standards, internal control has been
divided into the following five components:
-
Control environment;
-
Entity’s risk assessment process;
-
Information system, including the related business
processes, relevant to financial reporting, and communication
(‘Information System’);
-
Control activities; and
-
Monitoring of controls.
It is expected that the auditor addresses its effect on
the audit.
Control Environment:
-
management has created and maintained a culture of
honesty and ethical behaviour; and
-
the strengths in the control environment elements
collectively provide an appropriate foundation for the other components
of internal control and whether those other components are not
undermined by control environment weaknesses.
-
Communication and enforcement of integrity and
ethical values;
-
Commitment to competence;
-
Participation by those charged with governance;
-
Management’s philosophy and operating style;
-
Organizational structure;
-
Assignment of authority and responsibility;
-
Human resource policies and practices.
-
Audit Evidence for elements of the Control
Environment may be obtained through a combination of inquiries and other
risk assessment procedures such as corroborating inquiries through
observation or inspection of documents.
-
The control environment in itself does not prevent,
or detect and correct, a material misstatement. It may, however, influence
the auditor’s evaluation of the effectiveness of other controls and
thereby, the auditor’s assessment of the risks of material misstatement.
Entity’s Risk Assessment Process:
-
Identifying business risks relevant to financial
reporting objectives;
-
Estimating the significance of the risks;
-
Assessing the likelihood of their occurrence; and
-
Deciding about actions to address those risks.
-
The entity’s risk assessment process forms the basis
for how management determines the risks to be managed. If that process is
appropriate to the circumstances, it assists the auditor in identifying
risks of material misstatement. Whether the entity’s risk assessment
process is appropriate to the circumstances is a matter of judgment.
Information System:
-
Significant classes of transactions;
-
Procedures by which those transactions are
initiated, recorded, processed, corrected as necessary, transferred to
the general ledger and reported in the financial statements;
-
Related accounting records, supporting information
and specific accounts in the financial statements that are used to
initiate, record, process and report transactions;
-
Manner in which the significant events and
conditions are captured in the Information System;
-
Process used to prepare the financial statements;
-
Controls surrounding journal entries, including
non-standard journal entries used to record non-recurring, unusual
transactions or adjustments;
-
Manner in which the entity communicates financial
reporting roles and responsibilities and significant matters relating to
financial reporting.
Control Activities:
-
Control activities are the policies and procedures
that help ensure that management directives are carried out. The auditor
shall obtain an understanding of control activities relevant to the audit,
being those the auditor judges it necessary to understand in order to
assess the risks of material misstatement at the assertion level and
design further audit procedures responsive to assessed risks. An audit
requires an understanding of only those control activities related to
significant class of transactions, account balance, and disclosure in the
financial statements and the assertions which the auditor finds relevant
in his risk assessment process.
Monitoring of Controls:
-
the major activities that the entity uses to
monitor internal control over financial reporting, including those
related to those control activities relevant to the audit, and how the
entity initiates corrective actions to its controls.
-
the sources of the information used in the entity’s
monitoring activities, and the basis upon which management considers the
information to be sufficiently reliable for the purpose.
Identifying and Assessing the Risks of Material
Misstatement:
-
the financial statement level; and
-
the assertion level for classes of transactions,
account balances, and disclosures.
-
The auditor shall determine whether any of the risks
identified are, in the auditor’s judgment, a significant risk, considering
the followings:
-
Is the risk a risk of fraud;
-
Whether the risk is related to recent significant
economic, accounting or other developments and, therefore, requires
specific attention;
-
Complexity of transactions;
-
Whether the risk involves significant transactions
with related parties;
-
Degree of subjectivity in the measurement of
financial information related to the risk, especially those measurements
involving a wide range of measurement uncertainty; and
-
Whether the risk involves significant transactions
that are outside the normal course of business for the entity, or that
otherwise appear to be unusual.
Material Weakness in Internal Control:
Where the auditor has identified a material weakness in the
design, implementation or maintenance of internal control, he shall communicate
material weaknesses in internal control identified during the audit on a timely
basis to management at an appropriate level of responsibility, and with those
charged with governance.
Documentation:
The auditor shall document:
-
The sources of information from which the understanding
was obtained;
-
The risk assessment procedures performed;
-
The identified and assessed risks of material
misstatement at the financial statement level and at the assertion level;
and
-
The risks identified, and related controls about which
the auditor has obtained an understanding, as a result of the requirements
in paragraphs 26-29.
Considerations Specific to Smaller Entities:
-
Where audits are carried out entirely by the engagement
partner - sole practitioner, he having personally conducted the planning of
the audit, would be responsible for considering the susceptibility of the
entity’s financial statements to material misstatement due to fraud or
error.
-
The owner-manager may be able to exercise more
effective oversight than in a larger entity, which may compensate for the
generally more limited opportunities for segregation of duties. However, in
the circumstances, the owner-manager may be more able to override controls
because the system of internal control is less structured. This is taken
into account by the auditor when identifying the risks of material
misstatement due to fraud.
-
Audit evidence for elements of the control environment
in smaller entities may not be available in documentary form. Consequently,
the attitudes, awareness and actions of the owner-manager is of particular
importance to the
auditor’s understanding of a smaller entity’s control environment.
-
Information systems and related business processes
relevant to financial reporting in small entities are likely to be less
sophisticated than in larger entities. Understanding the entity’s systems
and processes may therefore be easier in an audit of smaller entities, and
may be more dependent on inquiry than on review of documentation. The need
to obtain an understanding, however, remains important.
Note: The date this standard (along with SA 330)
becomes effective, the existing AAS 6, ‘Risk Assessment and Internal
Control’, AAS 20, ‘Knowledge of the Business’ and AAS 29, ‘Auditing in a
Computer Information Systems Environment’ would stand withdrawn.
SA 330: The Auditor’s Responses to
Assessed Risks
Scope:
It deals with the auditor’s responsibility to design
and implement responses to the risks of material misstatement identified and
assessed by him in accordance with SA 315 in a financial statement audit.
Overall
Responses
-
The need for maintenance of professional
skepticism;
-
Assigning more experienced staff or those with
special skills or using experts;
-
More supervision;
-
Incorporating additional elements of
unpredictability in the selection of audit procedures to be performed;
-
Making general changes to the nature, timing, or
extent of audit procedures, for example: performing substantive
procedures at the period end instead of at an interim date;
-
An effective control environment may allow the
auditor to have more confidence in internal control and the reliability of
audit evidence generated internally within the entity and thus, for
example, allow the auditor to conduct some audit procedures at an interim
date rather than at the period end. Weaknesses in the control environment,
however, have the opposite effect. Accordingly, approach of the auditor
shall differ.
-
Based on the assessed risks of material misstatement
at the assertion level, the auditor shall design further audit procedures
to be performed whose nature, timing and extent are determined taking into
account:
-
the reasons for the assessment given to the risk of
material misstatement, like inherent risk due to the particular
characteristic of the class of transactions, account balance or
disclosure; and the control risk; and
-
Level of assessed risk – i.e., obtain more
persuasive audit evidence where the risk assessed is high. The auditor
may increase the quantity of the evidence, or obtain evidence that is
more relevant or reliable, e.g. by placing more emphasis on obtaining
third party evidence or by obtaining corroborating evidence from a
number of independent sources.
-
The tests of controls or substantive procedures or
both, as may be determined by the auditors, may be performed at an interim
date or at the period end. However, the Standard recognises that certain
audit procedures can be performed only at or after the period end, for
example:
-
Agreeing the financial statements to the accounting
records;
-
Examining adjustments made during the course of
preparing the financial statements; and
-
Procedures to respond to a risk that, at the period
end, the entity may have entered into improper sales contracts, or
transactions may not have been finalised.
-
The extent of an audit procedure judged necessary is
determined after considering the materiality, the assessed risk, and the
degree of assurance the auditor plans to obtain. In general, the extent of
audit procedures increases as the risk of material misstatement increases.
However, increasing the extent of an audit procedure is effective only if
the audit procedure itself is relevant to the specific risk.
-
The Standard also recognises that in certain
circumstances, the audit mandate or other special auditing requirements
may affect the auditor’s consideration of the nature, timing and extent of
further audit procedures.
Tests of Controls
-
Tests of controls shall be designed and performed
when the auditor’s assessment includes expectation that the controls are
operating effectively; or substantive procedures alone cannot provide
sufficient appropriate audit evidence at the assertion level. This may
occur, for example, when an entity conducts its business using IT and no
documentation of transactions is produced or maintained, other than
through the IT system.
-
The testing the operating effectiveness of controls
and obtaining an understanding of and evaluating the design and
implementation of controls require the use of the same type of audit
procedures. Therefore, the auditor may decide to test the operating
effectiveness of controls at the same time as evaluating their design and
determining that they have been implemented.
-
The auditor shall perform other audit procedures in
combination with inquiry to obtain audit evidence about the operating
effectiveness of the controls, including:
-
How the controls were applied at relevant times
during the period under audit;
-
The consistency with which they were applied;
-
By whom or by what means they were applied.
-
Changes to the programme are not made without being
subject to the appropriate programme change controls;
-
The authorized version of the programme is used for
processing transactions; and
-
Other relevant general controls are effective.
-
Where the controls to be tested depend upon other
controls (indirect controls) the auditor shall determine, whether it is
necessary to obtain audit evidence supporting the effective operation of
those indirect controls.
-
Timing of tests of controls would depend on the
auditor’s intended reliance. For example, audit evidence pertaining only
to a point in time may be sufficient for the auditor’s purpose when
testing controls over the entity’s physical inventory counting at the
period end. On the other hand, where the auditor intends to rely on a
control over a period, then a test which may include tests of the
entity’s monitoring of controls would be more appropriate.
-
While using audit evidence obtained during an interim
period, the auditor shall:
-
Obtain audit evidence about significant changes to
those controls subsequent to the interim period; and
-
Determine the additional audit evidence to be
obtained for the remaining period. (Ref: Paras. A33-A34 of the Standard
for the additional factors to be considered).
-
The effectiveness of the internal control,
including the control environment, the entity’s monitoring of controls,
and the entity’s risk assessment process;
-
Whether the lack of a change in a particular
control poses a risk due to changing circumstances;
-
The auditor shall establish the continuing
relevance of that evidence by obtaining further audit evidence, by
performing inquiry combined with observation or inspection, about
whether significant changes in those controls have occurred subsequent
to the previous audit.
-
If it is found that there have been changes
affecting its continuing relevance, then the auditor shall test the
controls in the current audit. In other cases, the auditor shall test
the controls at least once in every third audit, it being recognised
that the length of time between retesting such controls is also a matter
of professional judgment. Factors that may determine the period for
retesting a control, are given in Para A38 of the Standard. However, the
Standard also requires that the auditor shall test some controls during
each audit.
-
Other factors given in Para 13 of the Standard.
Evaluating the Operating Effectiveness of
Controls:
-
The auditor shall evaluate whether misstatements
detected by substantive procedures indicate that controls are not
operating effectively. The Standard also provides that the absence of
misstatements does not provide audit evidence that controls related to the
assertion being tested are effective.
-
When deviation from controls are detected, the
auditor shall make specific inquiries to understand these matters and
their potential consequences, and shall determine whether:
-
The tests of controls that have been performed
provide an appropriate basis for reliance on the controls;
-
Additional tests of controls are necessary; or
-
The potential risks of misstatement need to be
addressed using substantive procedures.
Substantive Procedures:
-
Irrespective of the assessed risks of material
misstatement, the auditor shall design and perform substantive procedures
for each material class of transactions, account balance, and disclosure.
-
Depending on the circumstances, the auditor may
determine the nature and extent of Substantive Procedures. For example the
auditor may decide to apply only analytical procedures (to a large volume
of transactions that tend to be predictable over time) or only tests of
details or combination of both.
-
The Standard requires that the substantive procedures
shall include the following audit procedures related to the financial
statement closing process:
-
Agreeing or reconciling the financial statements
with the underlying accounting records; and
-
Examining material journal entries and other
adjustments made during the course of preparing the financial
statements.
-
Where it is determined that an assessed risk of
material misstatement at the assertion level is a significant risk, the
Standard requires that the auditor shall perform substantive procedures
that are specifically responsive to that risk.
-
When substantive procedures are performed at an
interim date, the auditor shall cover the remaining period by performing
substantive procedures, combined with tests of controls for the
intervening period or further substantive procedures only, which provide a
reasonable basis for extending the audit conclusions from the interim date
to the period end.
-
If the misstatements not expected, when assessing the
risks of material misstatement, are detected at an interim date, the
auditor shall evaluate whether the related assessment of risk and the
planned nature, timing, or extent of substantive procedures covering the
remaining period need to be modified. In case the auditor concludes that
such modification is required, the modification may include extending or
repeating the procedures performed at the interim date at the period end.
-
As per the Standard, performing substantive
procedures at an interim date without undertaking additional procedures at
a later date increases the risk that the auditor will not detect
misstatements that may exist at the period end. Para A52 lists out the
factors which may influence whether to perform substantive procedures at
an interim date or not. Similarly, Para A53 lists out the factors which
may influence whether to perform substantive analytical procedures with
respect to the period between the interim date and the period end.
Adequacy of Presentation and Disclosure:
-
The auditor shall perform audit procedures to
evaluate whether the overall presentation of the financial statements,
including the related disclosures, is in accordance with the applicable
financial reporting framework.
Evaluating the Sufficiency and Appropriateness
of Audit Evidence:
-
Based on the audit procedures performed and the audit
evidence obtained, the auditor shall evaluate before the conclusion of the
audit whether the assessments of the risks of material misstatement at the
assertion level remain appropriate. If the same differs significantly from
the information on which the risk assessment was based, he may need to
reevaluate the planned audit procedures. SA 315 contains further guidance
on revising the auditor’s risk assessment.
-
The auditor is required to conclude if the sufficient
appropriate audit evidence, which may also include evidences that
contradict the assertions in the financial statements, has been obtained.
Where he is unable to do so, he shall express a qualified opinion or a
disclaimer of opinion.
Documentation:
-
overall responses to address the assessed risks of
material misstatement at the financial statement level;
-
the nature, timing, and extent of the further audit
procedures performed and its linkage with the assessed risks at the
assertion level;
-
the results of the audit procedures, including the
conclusions.
-
where the audit evidence obtained in previous
audits is used, he shall document the conclusions reached about relying
on such controls that were tested in a previous audit.
-
to demonstrate that the financial statements agree
or reconcile with the underlying accounting records.
