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:

  1. Standards on Auditing (SAs), to be applied in the audit of historical financial information.

  2. Standards on Review Engagements (SREs), to be applied in the review of historical financial information.

  3. Standards on Assurance Engagements (SAEs), to be applied in assurance engagements, dealing with subject matters other than historical financial information.

  4. 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.

  • Requirements:

  • Involvement of key members of the engagement team in planning and discussion.

  • 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.

  • Planning Activities:

  • Establishment of an overall audit strategy;

  • Develop an audit plan which includes:

  • 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.

  • Documentation:

  • 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.

  • Considerations Specific to Smaller Entities:

  • 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.

  • Requirements:

Risk Assessment Procedures and Related Activities:

  • The auditor shall perform risk assessment procedures which shall include:

  • 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.

  • Understanding of the entity and its environment:

  • The auditor shall obtain an understanding of the followings:

  • 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;

  • Qua the industry factors examples of matters, the auditor may consider include:

  • 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.

  • With reference to regulatory frameworks examples of matters, the auditor may consider include:

  • 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.

  • An understanding of the entity’s selection and application of accounting policies may encompass such matters as:

  • 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.

  • With reference to business risks the auditor does not have a responsibility to identify or assess all business risks because not all business risks give rise to risks of material misstatement. Examples of matters that the auditor may consider include:

  • 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.

  • The auditor shall evaluate the design of internal controls and determine whether they have been implemented, by performing procedures, which may include:

  • 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.

  • Appendix 1 to the Standard provides further explanation of these components of internal control.

  • Control Environment:

  • To understand the control environment the auditor shall evaluate whether:

  • 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.

  • Control environment includes followings:

  • 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:

  • The auditor shall obtain an understanding of whether the entity has a process for:

  • 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:

  • The auditor shall obtain an understanding of the Information System, including the following areas:

  • 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:

  • Monitoring of controls is a process to assess the effectiveness of internal control performance over time. The auditor shall obtain an understanding of:

  • 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:

  • To provide a basis for designing and performing further audit procedures, the auditor shall identify and assess the risks of material misstatement at:

  • 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.

  • Where a significant risk exists, the auditor shall obtain an understanding of the entity’s controls, including control activities.

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:

  • Minutes of the discussion among the engagement team and the significant decisions reached;

  • Key elements of the understanding obtained regarding each of the aspect of:

  • the entity and its environment specified in paragraph 11 of the Standard; and

  • the internal control components specified in paragraphs 14-23 of the Standard.

  • 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.

  • Requirements:

Overall Responses

  • In order to address the assessed risk of material misstatement at the financial statement level, the auditor shall design and implement overall responses which aims to or include:

  • 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.

  • Audit Procedures Responsive to the Assessed Risks of Material Misstatement at the Assertion Level

  • 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.

  • Where an entity conducts its business using IT and the auditor determines that an automated control is functioning as intended, the auditor may consider performing tests to determine that the control continues to function effectively. Such tests might include determining that:

  • 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).

  • While using audit evidence obtained in previous audits the auditor shall consider:

  • 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.

  • The auditor 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.

  • 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:

  • The auditor shall document:

  • 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.

  • Considerations specific to public sector entities:

  • Where the control activities are absent or insufficient, the undertaking of further audit procedures that is primarily substantive procedures in nature is desired.
