    Default Application and Other Explanatory Material An Audit of Financial Statements

    Application and Other Explanatory Material An Audit of Financial Statements

    Scope of the Audit (Ref: Para. 3)

    A1. The auditor’s opinion on the financial statements deals with whether the financial statements are prepared, in all material respects, in accordance with the applicable financial reporting framework. Such an opinion is common to all audits of financial statements. The auditor’s opinion therefore does not assure, for example, the future viability of the entity nor the efficiency or effectiveness with which management has conducted the affairs of the entity. In some
    jurisdictions, however, applicable law or regulation may require auditors to provide opinions on other specific matters, such as the effectiveness of internal control, or the consistency of a separate management report with the financial statements. While the ISAs include requirements and guidance in relation to such matters to the extent that they are relevant to forming an opinion on the financial statements, the auditor would be required to undertake further work if
    the auditor had additional responsibilities to provide such opinions.

    Preparation of the Financial Statements (Ref: Para. 4)

    A2. Law or regulation may establish the responsibilities of management and, where appropriate, those charged with governance in relation to financial reporting. However, the extent of these responsibilities, or the way in which they are described, may differ across jurisdictions. Despite these differences, an audit in accordance with ISAs is conducted on the premise that management and, where appropriate, those charged with governance have acknowledged and
    understand that they have responsibility:

    (a) For the preparation of the financial statements in accordance with the applicable financial reporting framework, including, where relevant, their fair presentation;

    (b) For such internal control as management and, where appropriate, those charged with governance determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error; and

    (c) To provide the auditor with:

    (i) Access to all information of which management and, where appropriate, those charged with governance are aware that is relevant to the preparation of the financial statements such as
    records, documentation and other matters;

    (ii) Additional information that the auditor may request from management and, where appropriate, those charged with governance for the purpose of the audit; and

    (iii) Unrestricted access to persons within the entity from whom the auditor determines it necessary to obtain audit evidence.

    A3. The preparation of the financial statements by management and, where appropriate, those charged with governance requires:

    • The identification of the applicable financial reporting framework, in the context of any relevant laws or regulations.

    • The preparation of the financial statements in accordance with that framework.

    • The inclusion of an adequate description of that framework in the financial statements.

    The preparation of the financial statements requires management to exercise judgment in making accounting estimates that are reasonable in the circumstances, as well as to select and apply appropriate accounting policies. These judgments are made in the context of the applicable financial reporting framework.

    A4. The financial statements may be prepared in accordance with a financial reporting framework designed to meet:

    • The common financial information needs of a wide range of users (that is, “general purpose financial statements”); or

    • The financial information needs of specific users (that is, “special purpose financial statements”).

    A5. The applicable financial reporting framework often encompasses financial reporting standards established by an authorized or recognized standards setting organization, or legislative or regulatory requirements. In some cases, the financial reporting framework may encompass both financial reporting standards established by an authorized or recognized standards setting organization and legislative or regulatory requirements. Other sources may provide direction on the application of the applicable financial reporting framework. In some cases, the applicable
    financial reporting framework may encompass such other sources, or may even consist only of such sources. Such other sources may include:

    • The legal and ethical environment, including statutes, regulations, court decisions, and professional ethical obligations in relation to accounting matters;

    • Published accounting interpretations of varying authority issued by standards setting, professional or regulatory organizations;

    • Published views of varying authority on emerging accounting issues issued by standards setting, professional or regulatory organizations;

    • General and industry practices widely recognized and prevalent; and

    • Accounting literature.

    Where conflicts exist between the financial reporting framework and the sources from which direction on its application may be obtained, or among the sources that encompass the financial reporting framework, the source with the highest authority prevails.

    A6. The requirements of the applicable financial reporting framework determine the form and content of the financial statements. Although the framework may not specify how to account for or disclose all transactions or events, it ordinarily embodies sufficient broad principles that can serve as a basis for developing and applying accounting policies that are consistent with the
    concepts underlying the requirements of the framework.

    A7. Some financial reporting frameworks are fair presentation frameworks, while others are compliance frameworks. Financial reporting frameworks that encompass primarily the financial reporting standards established by an organization that is authorized or recognized to promulgate standards to be used by entities for preparing general purpose financial statements are often designed to achieve fair presentation, for example, International Financial Reporting Standards (IFRSs) issued by the International Accounting Standards Board (IASB).

    A8. The requirements of the applicable financial reporting framework also determine what constitutes a complete set of financial statements. In the case of many frameworks, financial statements are intended to provide information about the financial position, financial performance and cash flows of an entity.

    For such frameworks, a complete set of financial statements would include a balance sheet; an income statement; a statement of changes in equity; a cash flow statement; and related notes. For some other financial reporting frameworks, a single financial statement and the related notes might constitute a complete set of financial statements:

    • For example, the International Public Sector Accounting Standard (IPSAS), “Financial Reporting Under the Cash Basis of Accounting” issued by the International Public Sector Accounting Standards Board states that the primary financial statement is a statement of cash receipts
    and payments when a public sector entity prepares its financial statements in accordance with that IPSAS.

    • Other examples of a single financial statement, each of which would include related notes, are:
    ○ Balance sheet.
    ○ Statement of income or statement of operations.
    ○ Statement of retained earnings.
    ○ Statement of cash flows.
    ○ Statement of assets and liabilities that does not include owner’s equity.
    ○ Statement of changes in owners’ equity.
    ○ Statement of revenue and expenses.
    ○ Statement of operations by product lines.

    A9. ISA 210 establishes requirements and provides guidance on determining the acceptability of the applicable financial reporting framework.5 ISA 800 deals with special considerations when financial statements are prepared in accordance with a special purpose framework.

    A10. Because of the significance of the premise to the conduct of an audit, the auditor is required to obtain the agreement of management and, where appropriate, those charged with governance that they acknowledge and understand that they have the responsibilities set out in paragraph A2 as a precondition for accepting the audit engagement.

    Considerations Specific to Audits in the Public Sector

    A11. The mandates for audits of the financial statements of public sector entities may be broader than those of other entities. As a result, the premise, relating to management’s responsibilities, on which an audit of the financial statements of a public sector entity is conducted may include additional responsibilities, such as the responsibility for the execution of transactions and events in accordance with law, regulation or other authority.

    Form of the Auditor’s Opinion (Ref: Para. 8)

    A12. The opinion expressed by the auditor is on whether the financial statements are prepared, in all material respects, in accordance with the applicable financial reporting framework. The form of the auditor’s opinion, however, will depend upon the applicable financial reporting framework and any applicable law or regulation. Most financial reporting frameworks include requirements relating
    to the presentation of the financial statements; for such frameworks, preparation of the financial statements in accordance with the applicable financial reporting framework includes presentation.

    A13. Where the financial reporting framework is a fair presentation framework, as is generally the case for general purpose financial statements, the opinion required by the ISAs is on whether the financial statements are presented fairly, in all material respects, or give a true and fair view. Where the financial reporting framework is a compliance framework, the opinion required is on
    whether the financial statements are prepared, in all material respects, in accordance with the framework. Unless specifically stated otherwise, references in the ISAs to the auditor’s opinion cover both forms of opinion.

    Default Professional Skepticism

    Professional Skepticism (Ref: Para. 15)

    A18. Professional skepticism includes being alert to, for example:

    • Audit evidence that contradicts other audit evidence obtained.
    • Information that brings into question the reliability of documents and responses to inquiries to be used as audit evidence.
    • Conditions that may indicate possible fraud.
    • Circumstances that suggest the need for audit procedures in addition to those required by the ISAs.

    A19. Maintaining professional skepticism throughout the audit is necessary if the auditor is, for example, to reduce the risks of:

    • Overlooking unusual circumstances.
    • Over generalizing when drawing conclusions from audit observations.
    • Using inappropriate assumptions in determining the nature, timing and extent of the audit procedures and evaluating the results thereof.

    A20. Professional skepticism is necessary to the critical assessment of audit evidence. This includes questioning contradictory audit evidence and the reliability of documents and responses to inquiries and other information obtained from management and those charged with governance. It also includes consideration of the sufficiency and appropriateness of audit evidence obtained
    in the light of the circumstances, for example, in the case where fraud risk factors exist and a single document, of a nature that is susceptible to fraud, is the sole supporting evidence for a material financial statement amount.

    A21. The auditor may accept records and documents as genuine unless the auditor has reason to believe the contrary. Nevertheless, the auditor is required to consider the reliability of information to be used as audit evidence.13 In cases of doubt about the reliability of information or indications of possible fraud (for example, if conditions identified during the audit cause the auditor to believe that a document may not be authentic or that terms in a document may have been falsified), the ISAs require that the auditor investigate further and determine what modifications or additions to audit procedures are necessary to resolve the matter.

    A22. The auditor cannot be expected to disregard past experience of the honesty and integrity of the entity’s management and those charged with governance. Nevertheless, a belief that management and those charged with governance are honest and have integrity does not relieve the auditor of the need to maintain professional skepticism or allow the auditor to be satisfied with less than persuasive audit evidence when obtaining reasonable assurance.

    Default Professional Judgment

    Professional Judgment (Ref: Para. 16)

    A23. Professional judgment is essential to the proper conduct of an audit. This is because interpretation of relevant ethical requirements and the ISAs and the informed decisions required throughout the audit cannot be made without the application of relevant knowledge and experience to the facts and circumstances. Professional judgment is necessary in particular regarding decisions about:

    • Materiality and audit risk.

    • The nature, timing and extent of audit procedures used to meet the requirements of the ISAs and gather audit evidence.

    • Evaluating whether sufficient appropriate audit evidence has been obtained, and whether more needs to be done to achieve the objectives of the ISAs and thereby, the overall objectives of the auditor.

    • The evaluation of management’s judgments in applying the entity’s applicable financial reporting framework.

    • The drawing of conclusions based on the audit evidence obtained, for example, assessing the reasonableness of the estimates made by management in preparing the financial statements.

    A24. The distinguishing feature of the professional judgment expected of an auditor is that it is exercised by an auditor whose training, knowledge and experience have assisted in developing the necessary competencies to achieve reasonable judgments.

    A25. The exercise of professional judgment in any particular case is based on the facts and circumstances that are known by the auditor. Consultation on difficult or contentious matters during the course of the audit, both within the engagement team and between the engagement team and others at the appropriate level within or outside the firm, such as that required by ISA 220,15 assist the auditor in making informed and reasonable judgments.

    A26. Professional judgment can be evaluated based on whether the judgment reached reflects a competent application of auditing and accounting principles and is appropriate in the light of, and consistent with, the facts and circumstances that were known to the auditor up to the date of the auditor’s report.

    A27. Professional judgment needs to be exercised throughout the audit. It also needs to be appropriately documented. In this regard, the auditor is required to prepare audit documentation sufficient to enable an experienced auditor, having no previous connection with the audit, to understand the significant professional judgments made in reaching conclusions on significant matters arising during the audit. Professional judgment is not to be used as the justification for decisions that are not otherwise supported by the facts and circumstances of the engagement or sufficient appropriate audit evidence.

    Default Sufficiency and Appropriateness of Audit Evidence

    Sufficient Appropriate Audit Evidence and Audit Risk (Ref: Para. 5 and 17)

    Sufficiency and Appropriateness of Audit Evidence

    A28. Audit evidence is necessary to support the auditor’s opinion and report. It is cumulative in nature and is primarily obtained from audit procedures performed during the course of the audit. It may, however, also include information obtained from other sources such as previous audits (provided the auditor has determined whether changes have occurred since the previous audit that may affect its relevance to the current audit17) or a firm’s quality control procedures for client acceptance and continuance. In addition to other sources inside and outside the entity, the entity’s accounting records are an important source of audit evidence. Also, information that may be used as audit evidence may have been prepared by an expert employed or engaged by the entity. Audit evidence comprises both information that supports and corroborates management’s assertions, and any information that contradicts such assertions. In addition, in some cases, the absence of information (for example, management’s refusal to provide a requested representation) is used by the auditor, and therefore, also constitutes audit evidence.

    Most of the auditor’s work in forming the auditor’s opinion consists of obtaining and evaluating audit evidence.

    A29. The sufficiency and appropriateness of audit evidence are interrelated. Sufficiency is the measure of the quantity of audit evidence. The quantity of audit evidence needed is affected by the auditor’s assessment of the risks of misstatement (the higher the assessed risks, the more audit evidence is likely to be required) and also by the quality of such audit evidence (the higher the quality, the less may be required). Obtaining more audit evidence, however, may not compensate for its poor quality.

    A30. Appropriateness is the measure of the quality of audit evidence; that is, its relevance and its reliability in providing support for the conclusions on which the auditor’s opinion is based. The reliability of evidence is influenced by its source and by its nature, and is dependent on the individual circumstances under which it is obtained.

    A31. Whether sufficient appropriate audit evidence has been obtained to reduce audit risk to an acceptably low level, and thereby enable the auditor to draw reasonable conclusions on which to base the auditor’s opinion, is a matter of professional judgment. ISA 500 and other relevant ISAs establish additional requirements and provide further guidance applicable throughout the audit regarding the auditor’s considerations in obtaining sufficient appropriate audit evidence.
    Audit Risk

    A32. Audit risk is a function of the risks of material misstatement and detection risk. The assessment of risks is based on audit procedures to obtain information necessary for that purpose and evidence obtained throughout the audit. The assessment of risks is a matter of professional judgment, rather than a matter capable of precise measurement.

    A33. For purposes of the ISAs, audit risk does not include the risk that the auditor might express an opinion that the financial statements are materially misstated when they are not. This risk is ordinarily insignificant. Further, audit risk is a technical term related to the process of auditing; it does not refer to the auditor’s business risks such as loss from litigation, adverse publicity, or other
    events arising in connection with the audit of financial statements. Risks of Material Misstatement

    A34. The risks of material misstatement may exist at two levels:
    • The overall financial statement level; and
    • The assertion level for classes of transactions, account balances, and disclosures.

    A35. Risks of material misstatement at the overall financial statement level refer to risks of material misstatement that relate pervasively to the financial statements as a whole and potentially affect many assertions.

    A36. Risks of material misstatement at the assertion level are assessed in order to determine the nature, timing and extent of further audit procedures necessary to obtain sufficient appropriate audit evidence. This evidence enables the auditor to express an opinion on the financial statements at an acceptably low level of audit risk. Auditors use various approaches to accomplish the objective of assessing the risks of material misstatement. For example, the auditor may make use of a model that expresses the general relationship of the components of audit risk in
    mathematical terms to arrive at an acceptable level of detection risk. Some auditors find such a model to be useful when planning audit procedures.

    A37. The risks of material misstatement at the assertion level consist of two components: inherent risk and control risk. Inherent risk and control risk are the entity’s risks; they exist independently of the audit of the financial statements.

    A38. Inherent risk is higher for some assertions and related classes of transactions, account balances, and disclosures than for others. For example, it may be higher for complex calculations or for accounts consisting of amounts derived from accounting estimates that are subject to significant estimation uncertainty.

    External circumstances giving rise to business risks may also influence inherent risk. For example, technological developments might make a particular product obsolete, thereby causing inventory to be more susceptible to overstatement. Factors in the entity and its environment that relate to several or all of the classes of transactions, account balances, or disclosures may also influence the inherent risk related to a specific assertion. Such factors may include, for example, a lack of sufficient working capital to continue operations or a declining industry characterized by a large number of business failures.

    A39. Control risk is a function of the effectiveness of the design, implementation and maintenance of internal control by management to address identified risks that threaten the achievement of the entity’s objectives relevant to preparation of the entity’s financial statements. However, internal control, no matter how well designed and operated, can only reduce, but not eliminate, risks of material misstatement in the financial statements, because of the inherent limitations of
    internal control. These include, for example, the possibility of human errors or mistakes, or of controls being circumvented by collusion or inappropriate management override. Accordingly, some control risk will always exist. The ISAs provide the conditions under which the auditor is required to, or may choose to, test the operating effectiveness of controls in determining the nature,
    timing and extent of substantive procedures to be performed.18

    A40. The ISAs do not ordinarily refer to inherent risk and control risk separately, but rather to a combined assessment of the “risks of material misstatement.” However, the auditor may make separate or combined assessments of inherent and control risk depending on preferred audit techniques or methodologies and practical considerations. The assessment of the risks of material misstatement may be expressed in quantitative terms, such as in percentages, or in non-quantitative terms. In any case, the need for the auditor to make appropriate risk assessments is more important than the different approaches by which they may be made.

    A41. ISA 315 establishes requirements and provides guidance on identifying and assessing the risks of material misstatement at the financial statement and assertion levels.

    Detection Risk

    A42. For a given level of audit risk, the acceptable level of detection risk bears an inverse relationship to the assessed risks of material misstatement at the assertion level. For example, the greater the risks of material misstatement the auditor believes exists, the less the detection risk that can be accepted and, accordingly, the more persuasive the audit evidence required by the auditor.

    A43. Detection risk relates to the nature, timing and extent of the auditor’s procedures that are determined by the auditor to reduce audit risk to an acceptably low level. It is therefore a function of the effectiveness of an audit procedure and of its application by the auditor. Matters such as:

    • adequate planning;
    • proper assignment of personnel to the engagement team;
    • the application of professional skepticism; and
    • supervision and review of the audit work performed, assist to enhance the effectiveness of an audit procedure and of its application and reduce the possibility that an auditor might select an inappropriate audit procedure, misapply an appropriate audit procedure, or misinterpret the audit results.

    A44. ISA 300 19 and ISA 330 establish requirements and provide guidance on planning an audit of financial statements and the auditor’s responses to assessed risks. Detection risk, however, can only be reduced, not eliminated, because of the inherent limitations of an audit. Accordingly, some detection risk will always exist.

    Inherent Limitations of an Audit

    A45. The auditor is not expected to, and cannot, reduce audit risk to zero and cannot therefore obtain absolute assurance that the financial statements are free from material misstatement due to fraud or error. This is because there are inherent limitations of an audit, which result in most of the audit evidence on which the auditor draws conclusions and bases the auditor’s opinion being persuasive rather than conclusive. The inherent limitations of an audit arise from:

    • The nature of financial reporting;
    • The nature of audit procedures; and
    • The need for the audit to be conducted within a reasonable period of time and at a reasonable cost.

    The Nature of Financial Reporting

    A46. The preparation of financial statements involves judgment by management in applying the requirements of the entity’s applicable financial reporting framework to the facts and circumstances of the entity. In addition, many financial statement items involve subjective decisions or assessments or a degree of uncertainty, and there may be a range of acceptable interpretations or judgments that may be made. Consequently, some financial statement items are
    subject to an inherent level of variability which cannot be eliminated by the application of additional auditing procedures. For example, this is often the case with respect to certain accounting estimates. Nevertheless, the ISAs require the auditor to give specific consideration to whether accounting estimates are reasonable in the context of the applicable financial reporting framework and related disclosures, and to the qualitative aspects of the entity’s accounting
    practices, including indicators of possible bias in management’s judgments. The Nature of Audit Procedures

    A47. There are practical and legal limitations on the auditor’s ability to obtain audit evidence. For example:

    • There is the possibility that management or others may not provide, intentionally or unintentionally, the complete information that is relevant to the preparation of the financial statements or that has been requested by the auditor. Accordingly, the auditor cannot be certain of the completeness of information, even though the auditor has performed audit procedures to obtain assurance that all relevant information has been obtained.

    • Fraud may involve sophisticated and carefully organized schemes designed to conceal it. Therefore, audit procedures used to gather audit evidence may be ineffective for detecting an intentional misstatement that involves, for example, collusion to falsify documentation which
    may cause the auditor to believe that audit evidence is valid when it is not. The auditor is neither trained as nor expected to be an expert in the authentication of documents.

    • An audit is not an official investigation into alleged wrongdoing.
    Accordingly, the auditor is not given specific legal powers, such as the power of search, which may be necessary for such an investigation. Timeliness of Financial Reporting and the Balance between Benefit and Cost

    A48. The matter of difficulty, time, or cost involved is not in itself a valid basis for the auditor to omit an audit procedure for which there is no alternative or to be satisfied with audit evidence that is less than persuasive. Appropriate planning assists in making sufficient time and resources available for the conduct of the audit. Notwithstanding this, the relevance of information, and thereby its value, tends to diminish over time, and there is a balance to be struck between the
    reliability of information and its cost. This is recognized in certain financial reporting frameworks (see, for example, the IASB’s “Framework for thePreparation and Presentation of Financial Statements”). Therefore, there is an expectation by users of financial statements that the auditor will form an opinion on the financial statements within a reasonable period of time and at a
    reasonable cost, recognizing that it is impracticable to address all information that may exist or to pursue every matter exhaustively on the assumption that information is in error or fraudulent until proved otherwise.

    A49. Consequently, it is necessary for the auditor to:

    • Plan the audit so that it will be performed in an effective manner;
    • Direct audit effort to areas most expected to contain risks of material misstatement, whether due to fraud or error, with correspondingly less effort directed at other areas; and
    • Use testing and other means of examining populations for misstatements.

    A50. In light of the approaches described in paragraph A49, the ISAs contain requirements for the planning and performance of the audit and require the auditor, among other things, to:

    • Have a basis for the identification and assessment of risks of material misstatement at the financial statement and assertion levels by performing risk assessment procedures and related activities; and

    • Use testing and other means of examining populations in a manner that provides a reasonable basis for the auditor to draw conclusions about the population.

    Other Matters that Affect the Inherent Limitations of an Audit

    A51. In the case of certain assertions or subject matters, the potential effects of the inherent limitations on the auditor’s ability to detect material misstatements are particularly significant. Such assertions or subject matters include:

    • Fraud, particularly fraud involving senior management or collusion. See ISA 240 for further discussion.

    • The existence and completeness of related party relationships and transactions. See ISA 55023 for further discussion.

    • The occurrence of non-compliance with laws and regulations. See ISA 25024 for further discussion.

    • Future events or conditions that may cause an entity to cease to continue as a going concern. See ISA 57025 for further discussion. Relevant ISAs identify specific audit procedures to assist in mitigating the effect of the inherent limitations.

    A52. Because of the inherent limitations of an audit, there is an unavoidable risk that some material misstatements of the financial statements may not be detected, even though the audit is properly planned and performed in accordance with ISAs. Accordingly, the subsequent discovery of a material misstatement of the financial statements resulting from fraud or error does not by itself indicate a failure to conduct an audit in accordance with ISAs. However, the inherent
    limitations of an audit are not a justification for the auditor to be satisfied with less than persuasive audit evidence. Whether the auditor has performed an audit in accordance with ISAs is determined by the audit procedures performed in the circumstances, the sufficiency and appropriateness of the audit evidence obtained as a result thereof and the suitability of the auditor’s report based on an evaluation of that evidence in light of the overall objectives of the auditor.

    Default Conduct of an Audit in Accordance with ISAs

    Conduct of an Audit in Accordance with ISAs
    Nature of the ISAs (Ref: Para. 18)

    A53. The ISAs, taken together, provide the standards for the auditor’s work in fulfilling the overall objectives of the auditor. The ISAs deal with the general responsibilities of the auditor, as well as the auditor’s further considerations relevant to the application of those responsibilities to specific topics.

    A54. The scope, effective date and any specific limitation of the applicability of a specific ISA is made clear in the ISA. Unless otherwise stated in the ISA, the auditor is permitted to apply an ISA before the effective date specified therein.

    A55. In performing an audit, the auditor may be required to comply with legal or regulatory requirements in addition to the ISAs. The ISAs do not override law or regulation that governs an audit of financial statements. In the event that such law or regulation differs from the ISAs, an audit conducted only in accordance with law or regulation will not automatically comply with ISAs.

    A56. The auditor may also conduct the audit in accordance with both ISAs and auditing standards of a specific jurisdiction or country. In such cases, in addition to complying with each of the ISAs relevant to the audit, it may be necessary for the auditor to perform additional audit procedures in order to comply with the relevant standards of that jurisdiction or country.

    Considerations Specific to Audits in the Public Sector

    A57. The ISAs are relevant to engagements in the public sector. The public sector auditor’s responsibilities, however, may be affected by the audit mandate, or by obligations on public sector entities arising from law, regulation or other authority (such as ministerial directives, government policy requirements, or resolutions of the legislature), which may encompass a broader scope than an audit of financial statements in accordance with the ISAs. These additional
    responsibilities are not dealt with in the ISAs. They may be dealt with in the pronouncements of the International Organization of Supreme Audit Institutions or national standard setters, or in guidance developed by

    government audit agencies.

    Contents of the ISAs (Ref: Para. 19)

    A58. In addition to objectives and requirements (requirements are expressed in the ISAs using “shall”), an ISA contains related guidance in the form of application and other explanatory material. It may also contain introductory material that provides context relevant to a proper understanding of the ISA, and definitions. The entire text of an ISA, therefore, is relevant to an understanding of the objectives stated in an ISA and the proper application of the requirements of an ISA.

    A59. Where necessary, the application and other explanatory material provides further explanation of the requirements of an ISA and guidance for carrying them out. In particular, it may:

    • Explain more precisely what a requirement means or is intended to cover.
    • Include examples of procedures that may be appropriate in the circumstances.

    While such guidance does not in itself impose a requirement, it is relevant to the proper application of the requirements of an ISA. The application and other explanatory material may also provide background information on matters addressed in an ISA.

    A60. Appendices form part of the application and other explanatory material. The purpose and intended use of an appendix are explained in the body of the related ISA or within the title and introduction of the appendix itself.

    A61. Introductory material may include, as needed, such matters as explanation of:
    • The purpose and scope of the ISA, including how the ISA relates to other ISAs.
    • The subject matter of the ISA.
    • The respective responsibilities of the auditor and others in relation to the subject matter of the ISA.
    • The context in which the ISA is set.

    A62. An ISA may include, in a separate section under the heading “Definitions,” a description of the meanings attributed to certain terms for purposes of the ISAs. These are provided to assist in the consistent application and interpretation of the ISAs, and are not intended to override definitions that may be established for other purposes, whether in law, regulation or otherwise. Unless otherwise indicated, those terms will carry the same meanings throughout the ISAs. The Glossary of Terms relating to International Standards issued by the International Auditing and
    Assurance Standards Board in the Handbook of International Quality Control, Auditing, Review, Other Assurance, and Related Services Pronouncements published by IFAC contains a complete listing of terms defined in the ISAs. It also includes descriptions of other terms found in ISAs to assist in common and consistent interpretation and translation.

    A63. When appropriate, additional considerations specific to audits of smaller entities and public sector entities are included within the application and other explanatory material of an ISA. These additional considerations assist in the application of the requirements of the ISA in the audit of such entities. They do not, however, limit or reduce the responsibility of the auditor to apply and
    comply with the requirements of the ISAs.

    Considerations Specific to Smaller Entities

    A64. For purposes of specifying additional considerations to audits of smaller entities, a “smaller entity” refers to an entity which typically possesses qualitative characteristics such as:
    (a) Concentration of ownership and management in a small number of individuals (often a single individual – either a natural person or another enterprise that owns the entity provided the owner exhibits the relevant qualitative characteristics); and

    (b) One or more of the following:
    (i) Straightforward or uncomplicated transactions;
    (ii) Simple record-keeping;
    (iii) Few lines of business and few products within business lines;
    (iv) Few internal controls;
    (v) Few levels of management with responsibility for a broad range of controls; or
    (vi) Few personnel, many having a wide range of duties.


    These qualitative characteristics are not exhaustive, they are not exclusive to smaller entities, and smaller entities do not necessarily display all of these characteristics.

    A65. The considerations specific to smaller entities included in the ISAs have been developed primarily with unlisted entities in mind. Some of the considerations, however, may be helpful in audits of smaller listed entities.

    A66. The ISAs refer to the proprietor of a smaller entity who is involved in running the entity on a day-to-day basis as the “owner-manager.” Objectives Stated in Individual ISAs (Ref: Para. 21)

    A67. Each ISA contains one or more objectives which provide a link between the requirements and the overall objectives of the auditor. The objectives in individual ISAs serve to focus the auditor on the desired outcome of the ISA, while being specific enough to assist the auditor in:

    • Understanding what needs to be accomplished and, where necessary, the appropriate means of doing so; and
    • Deciding whether more needs to be done to achieve them in the particular circumstances of the audit.


    A68. Objectives are to be understood in the context of the overall objectives of the auditor stated in paragraph 11 of this ISA. As with the overall objectives of the auditor, the ability to achieve an individual objective is equally subject to the inherent limitations of an audit.

    A69. In using the objectives, the auditor is required to have regard to the interrelationships among the ISAs. This is because, as indicated in paragraph A53, the ISAs deal in some cases with general responsibilities and in others with the application of those responsibilities to specific topics. For example, this ISA requires the auditor to adopt an attitude of professional skepticism; this is necessary in all aspects of planning and performing an audit but is not repeated as a
    requirement of each ISA. At a more detailed level, ISA 315 and ISA 330 contain, among other things, objectives and requirements that deal with the auditor’s responsibilities to identify and assess the risks of material misstatement and to design and perform further audit procedures to respond to those assessed risks, respectively; these objectives and requirements apply throughout the audit. An ISA dealing with specific aspects of the audit (for example, ISA 540) may expand on how the objectives and requirements of such ISAs as ISA 315 and ISA 330 are to
    be applied in relation to the subject of the ISA but does not repeat them. Thus, in achieving the objective stated in ISA 540, the auditor has regard to the objectives and requirements of other relevant ISAs.

    Use of Objectives to Determine Need for Additional Audit Procedures (Ref: Para. 21(a))

    A70. The requirements of the ISAs are designed to enable the auditor to achieve the objectives specified in the ISAs, and thereby the overall objectives of the auditor. The proper application of the requirements of the ISAs by the auditor is therefore expected to provide a sufficient basis for the auditor’s achievement of the objectives. However, because the circumstances of audit engagements vary widely and all such circumstances cannot be anticipated in the ISAs, the
    auditor is responsible for determining the audit procedures necessary to fulfill the requirements of the ISAs and to achieve the objectives. In the circumstances of an engagement, there may be particular matters that require the auditor to perform audit procedures in addition to those required by the ISAs to meet the objectives specified in the ISAs.

    Use of Objectives to Evaluate Whether Sufficient Appropriate Audit Evidence Has Been Obtained (Ref: Para. 21(b))

    A71. The auditor is required to use the objectives to evaluate whether sufficient appropriate audit evidence has been obtained in the context of the overall objectives of the auditor. If as a result the auditor concludes that the audit evidence is not sufficient and appropriate, then the auditor may follow one or more of the following approaches to meeting the requirement of paragraph 21(b):

    • Evaluate whether further relevant audit evidence has been, or will be, obtained as a result of complying with other ISAs;
    • Extend the work performed in applying one or more requirements; or
    • Perform other procedures judged by the auditor to be necessary in the circumstances.

    Where none of the above is expected to be practical or possible in the circumstances, the auditor will not be able to obtain sufficient appropriate audit evidence and is required by the ISAs to determine the effect on the auditor’s report or on the auditor’s ability to complete the engagement.

    Complying with Relevant Requirements
    Relevant Requirements (Ref: Para. 22)

    A72. In some cases, an ISA (and therefore all of its requirements) may not be relevant in the circumstances. For example, if an entity does not have an internal audit function, nothing in ISA 61026 is relevant.

    A73. Within a relevant ISA, there may be conditional requirements. Such a requirement is relevant when the circumstances envisioned in the requirement apply and the condition exists. In general, the conditionality of a requirement will either be explicit or implicit, for example:
    • The requirement to modify the auditor’s opinion if there is a limitation of scope represents an explicit conditional requirement.
    • The requirement to communicate significant deficiencies in internal control identified during the audit to those charged with governance, which depends on the existence of such identified significant deficiencies; and the requirement to obtain sufficient appropriate audit evidence regarding the presentation and disclosure of segment information in accordance with the
    applicable financial reporting framework, which depends on that framework requiring or permitting
    such disclosure, represent implicit conditional requirements.

    In some cases, a requirement may be expressed as being conditional on applicable law or regulation. For example, the auditor may be required to withdraw from the audit engagement, where withdrawal is possible under applicable law or regulation, or the auditor may be required to do something, unless prohibited by law or regulation. Depending on the jurisdiction, the legal
    or regulatory permission or prohibition may be explicit or implicit.

    Departure from a Requirement (Ref: Para. 23)

    A74. ISA 230 establishes documentation requirements in those exceptional circumstances where the auditor departs from a relevant requirement. The ISAs do not call for compliance with a requirement that is not relevant in the circumstances of the audit.

    Failure to Achieve an Objective (Ref: Para. 24)

    A75. Whether an objective has been achieved is a matter for the auditor’s professional judgment. That judgment takes account of the results of audit procedures performed in complying with the requirements of the ISAs, and the auditor’s evaluation of whether sufficient appropriate audit evidence has been obtained and whether more needs to be done in the particular circumstances of
    the audit to achieve the objectives stated in the ISAs. Accordingly, circumstances that may give rise to a failure to achieve an objective include those that:

    • Prevent the auditor from complying with the relevant requirements of an ISA.

    • Result in its not being practicable or possible for the auditor to carry out the additional audit procedures or obtain further audit evidence as determined necessary from the use of the objectives in accordance with paragraph 21, for example, due to a limitation in the available audit evidence.

    A76. Audit documentation that meets the requirements of ISA 230 and the specific documentation requirements of other relevant ISAs provides evidence of the auditor’s basis for a conclusion about the achievement of the overall objectives of the auditor. While it is unnecessary for the auditor to document separately (as in a checklist, for example) that individual objectives have been achieved, the documentation of a failure to achieve an objective assists the auditor’s
    evaluation of whether such a failure has prevented the auditor from achieving the overall objectives of the auditor.
