STANDARD No. 320 AUDIT MATERIALITY (Promulgated together with the Finance Minister's Decision No. 28/2003/QD-BTC of March 14, 2003) GENERAL PROVISIONS 01. The purpose of this standard is to prescribe the basic principles and procedures and guide the modes of application thereof to the responsibilities of auditors and audit firms when determining materiality in auditing financial statements and the relationship between materiality and audit risk. 02. When conducting audits, auditors must pay attention to materiality and its relationship with audit risk. 03. This standard shall apply to the audit of the financial statements and also to the audit of other financial information of audit firms. Auditors and audit firms must observe the provisions of this standard in the process of auditing the financial statements. The audited units (clients) and the users of audit results must possess necessary knowledge of this standard so as to cooperate in working and handling relationships relating to the determination of materiality of audited information. The terms in this standard shall be construed as follows: 04. Materiality is the concept used to express the importance of a piece of information (an accounting figure) in the financial statements. Information is regarded as material if its omission or inaccuracy could influence the decisions of users of the financial statements. Materiality depends on the magnitude and nature of information or error judged in particular circumstances. Materiality is a threshold or cut-off point rather than a content which information must have. Information materiality must be considered both quantitatively and qualitatively. CONTENTS OF THE STANDARD Materiality 05. The objective of the audit of financial statements is to enable auditors and audit firms to confirm whether or not the financial statements have been made in accordance with the current (or accepted) accounting standards and regimes, with relevant laws and honestly or rationally reflect material aspects. The determination of the level of materiality is a matter of professional judgment of auditors. 06. When planning audits, auditors must determine an acceptable materiality level to serve as a basis for detecting quantitatively material errors. However, to judge errors as material, auditors must consider them both quantitatively and qualitatively. For example, non-compliance with the current accounting regimes may be considered a material error if it leads to the incorrect presentation of indexes in the financial statements, thus making users of financial information misunderstand the nature of the matters; or the financial statements fail to describe matters relating to non-continuous activities of enterprises. 07. Auditors should consider the possibility of relatively small errors that, if added up, could have a material effect on the financial statements, such as an error in a month-end accounting procedure may become a potential material error if it is repeated each month. 08. Auditors should consider materiality in terms of the extent of erroneousness of the financial statements as a whole in relation to detailed errors in individual account balances, transactions and information disclosed in the financial statements. Materiality may be influenced by other factors such as legal requirements or matters related to different financial statement items and the relationships between these items. In the process of consideration, different materiality levels may be discovered, depending on the nature of matters put forward in the audited financial statements. 09. Auditors must determine materiality when: a/ Determining the contents, timing and scope of auditing procedures; b/ Evaluating the effect of errors. The relationship between materiality and audit risk 10. When planning audits, auditors must consider factors which may give rise to material errors in the financial statements. The auditors' assessment of materiality relating to account balances and major transactions shall help the auditors determine which items to be examined and decide to use sampling or analytical procedures. The materiality assessment relating to account balances and major transactions shall help the auditors select suitable audit procedures that, when combined, shall reduce audit risk to an acceptable level. 11. There is an inverse relationship between materiality and audit risk in an audit: The higher the materiality level is, the lower the audit risk would be and vice versa. Auditors should take this relationship into account when determining the contents, timing and scope of audit procedures in an appropriate manner, such as when planning audits, if auditors determine that the acceptable materiality level is low, audit risk is increased. In this case, auditors may: a/ Reduce the assessed level of control risk by carrying out extended or additional tests of control so as to prove the reduced level of control risk; or b/ Reduce detection risk by modifying the contents, timing and scope of detailed examination procedures already planned. Materiality and audit risk in evaluating audit evidences 12. The auditors' materiality and audit risk assessment results at the time of initially planning the audits may be different from the assessment results at different times in the auditing process. Such difference could be attributed to a change in practical circumstances or a change in the auditors' knowledge of the audited units on the basis of the obtained audit results, such as when the audit is planned before the end of a fiscal year, the auditors have assessed materiality and audit risk on the basis of the enterprises' anticipated operation results and financial situation. If the enterprises' actual financial situation and operation results are substantially different therefrom, the assessment of materiality and audit risk will also change. Moreover, when planning audits, auditors usually set the acceptable materiality level lower than that is used to evaluate the audit results in order to increase the possibility to detect errors. Evaluation of the effect of errors 13. When evaluating the financial statements' honesty and rationality, auditors must assess whether the aggregate of uncorrected errors which have been detected in the auditing process constitutes a material error or not. 14. The aggregate of uncorrected errors comprises: a/ Errors detected by auditors in the current year, including those detected in the previous years and not yet corrected in the audit year; b/ The auditors' estimation of other errors which cannot be specifically determined (projected errors) in the financial statements of the audit year. 15. Auditors should consider whether the aggregate of uncorrected errors may be material or not. If they conclude that the aggregate of such errors is material, they should take action to reduce audit risk by adding necessary audit procedures or requesting the directors of the audited units to adjust the financial statements. 16. Where the directors of the audited units refuse to adjust the financial statements and the results of application of additional audit procedures permit the auditors to conclude that the aggregate of uncorrected errors is material, they should consider and modify the auditing reports in accordance with Vietnamese Auditing Standard No. 700 "Auditing reports on financial statements." 17. If the aggregate of uncorrected errors which have been detected approximates the set materiality level, auditors must consider the possibility that whether the undetected errors, when combined with those detected but uncorrected, could constitute material errors or not. In this case, auditors should reduce audit risk by adding necessary audit procedures or requesting the directors to adjust the financial statements to correct the detected errors. STANDARD 501 ADDITIONAL AUDIT EVIDENCES FOR SPECIAL ITEMS AND EVENTS (Promulgated together with the Finance Minister's Decision No. 28/2003/QD-BTC of March 14, 2003) GENERAL PROVISIONS 01. The purpose of this standard is to prescribe the basic principles and procedures and guide modes of application thereof to the gathering of additional audit evidences for special items and events in the process of auditing financial statements. The principles and procedures prescribed in this standard supplement those prescribed in Standard No. 500 "Audit evidences." 02. The application of the principles and procedures described in this standard shall assist auditors and audit firms in obtaining sufficient appropriate audit evidences for special items in the financial statements and several related events. 03. This standard shall apply to the audit of financial statements and also to the audit of other financial information and related services of audit firms. Auditors and audit firms must observe the provisions of this standard in the process of conducting audits. The audited units (clients) and users of the audit results must possess necessary knowledge of this standard so as to cooperate in dealing with relationships relating to the supply and gathering of audit evidences for special items and events. CONTENTS OF THE STANDARD 04. Special items and events in the audit of financial statements normally include: - Inventory; - Receivables; - Long-term investments; - Litigation and dispute cases; - Information on various domains or geographical areas. Whether items and events are determined as special or not depends on each audited unit and the assessment of auditors. When determining that items or events are special, auditors must perform the following: Participation in inventory counts 05. The audited units must establish inventory counting procedures and count inventory physically at least once a year to serve as a basis for checking the reliability of the regular declaration system and for preparing financial statements. 06. When inventory is determined as material to the financial statements, auditors must gather sufficient appropriate audit evidences regarding the existence and conditions of inventory by participating in physical inventory counts unless such participation is impossible. When the units count inventory, auditors may only supervise the counting or directly join in counting inventory samples so as to gather evidences regarding compliance with the counting procedures and check the reliability of these procedures. 07. If unable to participate in the physical inventory counts on the planned date, auditors must re-count a number of commodity items on another date and, when necessary, check inventory fluctuations occurring before the time of recounting and after the time the units take the count. 08. If unable to participate in the count, for example due to the nature and location of the count, auditors must determine whether they can carry out alternative inspection procedures in order to gather sufficient appropriate evidences regarding the existence and conditions of inventory, so that they can avoid to express an exclusion opinion because of the limitation in the auditing scope, for example, checking sale vouchers after the date of physical inventory count may provide appropriate audit evidences. 09. If auditors plan to participate in the physical inventory count or carry out alternative inspection procedures, they must consider the following factors: - The characteristics of the accounting and internal control systems relating to inventory; - Inherent, control and detection risks, and materiality of the item of inventory; - Whether or not the inventory counting procedures have been established and instructed to inventory counters; - The inventory count plan; - The locations of inventory counting; - The necessity to invite experts to participate in the counting. 10. Where auditors have participated in the physical inventory count one or more times during the year, they only need to observe the carrying out of counting procedures and check inventory samples. 11. If units estimate the inventory quantity, such as estimating a coal pile, auditors must consider the reasonableness of this method of estimation. 12. When the physical inventory count is taken simultaneously at various locations, auditors must select appropriate locations for participation in the count, depending on the materiality of the category of inventory and the assessment of inherent and control risk at these locations. 13. Auditors must check the audited units' regulations on inventory count: a/ The application of control procedures, such as checking of methods of weighing, measuring, counting, receiving and delivering inventory; procedures for recording warehouse books, warehouse cards, recording of count cards and summing of count results; b/ The determination of unfinished products, slow-moving, obsolete or damaged goods, goods sent for processing, to agents or on consignment, goods received for processing, for agency sale...; c/ The determination of appropriate procedures relating to the internally circulated goods, goods received and delivered before and after the counting date. 14. To ensure the inventory count procedures be strictly complied with, auditors must supervise the carrying out of these procedures and may directly participate in the sample count. Auditors must check both the accuracy and completeness of the count cards by selecting and checking a number of commodity items actually kept in the warehouses for comparison with the count cards or selecting and checking a number of count cards for comparison with the goods actually kept in the warehouses. Of the checked count cards, auditors should consider which ones need to be retained for subsequent checking and comparison. 15. Auditors should also consider period-end procedures, mostly details of the value of inventory moved just before, during and after the count so that the accounting of such value can be checked later. 16. In practice, the physical inventory count may be conducted at a time other than period end. This method will normally apply to audits only when control risk is assessed as low or average. In this case, auditors must carry out appropriate procedures to consider whether fluctuations in inventory between the count date and the period-end date are correctly accounted or not. 17. If the audited units apply the periodical count method for accounting inventory, the value of inventory is determined at the period-end, but auditors must carry out several additional procedures to assess whether or not the reasons for any significant differences between the count data and the data in accounting books have been determined by the units and to check whether or not such differences have been adjusted. 18. Auditors must check the year-end lists of counted inventory to determine whether they reflect fully and accurately the actual inventory quantities or not. 19. Where inventory is under the control or custody of a third party, auditors must request the third party to directly confirm the quantities and conditions of inventory held by the third party on behalf of the unit. Depending on materiality of this inventory, auditors should also consider the following factors: - The integrity and independence of the third party; - The necessity to directly participate in the count or to invite other auditors or audit firms to participate in the count; - The necessity to have other auditors' reports on the compatibility of the third party's accounting and internal control systems for ensuring that inventory is correctly counted and carefully preserved. - The necessity to examine inventory-related documents held by the third party, for example, warehouse receipts, confirmations from other parties that they are holding such inventory as collateral. Confirmation of receivables 20. Where receivables are determined as material to the financial statements and when it is likely that debtors will respond, auditors must plan to request these debtors to confirm such receivables or data constituting the account balance of receivables. 21. Direct confirmation shall provide reliable audit evidences regarding the existence of receivables and the accuracy of account balances. However, such confirmation does not normally provide sufficient evidences regarding the recoverability of receivables or regarding the existence of unaccounted receivables. 22. Where auditors assume that debtors will not respond to letters of request for confirmation of receivables, they must plan alternative procedures, for example, examining documents constituting the account balance of receivables. 23. Auditors may sort out receivables which need to be confirmed so as to ensure the existence and accuracy of receivables as a whole, taking into account receivables that may affect identified audit risk and other planned audit procedures. 24. Letters of request for confirmation of receivables shall be sent by auditors, clearly stating the authorization by the audited units and the permission for debtors to supply information directly to auditors. 25. Auditors' letters of request for confirmation of receivables (possibly including confirmation of payables) in Vietnam dong and in foreign currency (if any) may take two forms: - Form A: clearly stating the amount of receivables and requesting debtors to confirm it is correct or how much it is; - Form B: not stating the amount of receivables but requesting debtors to clearly indicate the amount of receivables or express different opinions. 26. Form-A confirmation (see paragraph 25) provide audit evidences more reliable than form-B confirmation (see paragraph 25). The selection of either form depends on each specific circumstance and the auditors' assessment of potential risk and control risk. Form-A confirmation is more appropriate when potential risk and control risk are assessed as high. 27. Auditors may combine both forms of confirmation above. For example, when the total of receivables consists of a small number of large receivables and a large number of small receivables, auditors may request Form-A confirmation for all or some large receivables and accept Form-B confirmation for a large number of small receivables. 28. Past a reasonable period of time after sending letters of request for debt confirmation, if receiving no replies from debtors, auditors may send a reminder letter to them. Letters of confirmation of exceptional cases should be more thoroughly investigated. 29. Auditors must perform alternative procedures or continue investigating and/or interviewing when: - No reply is received; - Replies confirm debt amounts different from the balances of the audited units; - Replies contain different opinions. After performing alternative procedures or continuing investigating and/or interviewing, if finding that there is still not enough reliable evidences or it is impossible to perform alternative procedures, any difference shall be regarded as an error. For example, performing alternative procedures such as examining sales invoice and receipts of receivables for which no reply is received. 30. In practice, when control risk is assessed as low, auditors may request confirmation of the balance of receivables at a time other than the last day of the fiscal year. For example, if auditors must finish the audit work within a very short time limit after the last day of a year, they must examine all transactions occurring between the time when the balance of receivables is confirmed and the last day of the fiscal year. 31. Where the directors of the audited units request auditors not to send letters of request for confirmation to a number of debtors, auditors must consider whether such requests are justified or not. For example, if a receivable is being disputed between the two parties or if requests for confirmation of debts would badly affect on-going negotiations between the units and debtors. Before accepting such requests, auditors must consider evidences supporting the directors' explanations. In this cases, auditors must apply alternative procedures for the balance of receivables for which letters of request for confirmation must not be sent. Valuation and presentation of long-term investments 32. If long-term investments are regarded as material to the financial statements, auditors must gather sufficient appropriate audit evidences regarding the valuation and presentation of long-term investments. 33. The procedures for auditing long-term investments normally aim to determine whether or not the units have the ability and intend to hold these long-term investments and must gather written representation to that effect. 34. The audit procedures normally include the examination of financial statements and other relevant information, such as determination and comparison of the market prices of securities with the book value of long-term investments up to the date of the auditing reports. 35. If the market prices are lower than the book value, auditors must consider the necessity to set up price decrease reserves. If doubting the recoverability of investments, auditors must take into account appropriate adjustments and explanations presented in the financial statements. Litigation and dispute cases 36. Litigation and dispute cases involving the audited units, which may have a material effect on the financial statements, must be presented in the financial statements as provided for. 37. Auditors must carry out procedures to identify litigation and dispute cases involving the units, which may have a material effect on the financial statements. These procedures include: - Inquiring the directors, asking for written representations; - Examining minutes of meetings of the management boards and correspondence with the units' legal advisors; - Examining legal advise expenses; - Using all information relating to litigation and dispute cases. 38. When litigation and/or dispute cases have been identified or when auditors doubt that they may exist, they must request the units' legal advisors to directly supply information. With this method, they can obtain sufficient appropriate audit evidences regarding the cases as well as the degree of damage affecting the units' financial statements. 39. Letters of request for the units' legal advisors to supply information on litigation and/or dispute cases must be signed by the audited units and sent by auditors. Such a letter contains the following contents: - A list of litigation and/or dispute cases; - The assessment by the audited unit's director of the consequences of the litigation and/or dispute cases and estimation of their financial impacts, including related legal expenses. - A request that the unit's legal advisor confirms the reasonableness of the director's assessments and provides the auditors with further information 40. Auditors must consider the happenings of litigation and/or dispute cases up to the date of signing of the auditor' reports. When necessary, auditors may gather updated information from legal advisors. 41. Where the cases are very complicated or there is disagreement between the directors of the audited units and their legal advisors, auditors must meet with the legal advisors to discuss the consequences of the cases. Such meetings must be consented by the directors of the audited units and attended by representatives of the units' directorates. 42. Where the directors of the audited units refuse to permit auditors to meet with the units' legal advisors, this will constitute a limitation in the auditing scope and auditors must give a partial acceptance opinion or an opinion on refusal to express opinion. Where the clients' legal advisors refuse to reply with plausible reasons and auditors are also unable to gather sufficient audit evidences by applying alternative procedures, the auditors must consider whether this constitutes a limitation in the auditing scope and thus may express a partial acceptance opinion or an opinion on refusal to express opinion Information on various domains or geographical areas 43. Where information relating to various domains and geographical areas is regarded as material to the financial statements, auditors must gather sufficient appropriate audit evidences regarding the information which needs to be disclosed in the financial statements in accordance with the current accounting standards. 44. Auditors must consider information relating to various domains and geographical areas in relation to the financial statements taken as a whole. Auditors are not required to apply audit procedures in order to express their own opinions on information relating to various domains and geographical areas. However, the concept of materiality must encompass both quantitative and qualitative factors and the auditors' procedures used for determining material information must reckon this. 45. The audit procedures for information relating to various domains and geographical areas normally consist of analytical procedures and audit tests appropriate in each specific circumstance. 46. Auditors should discuss with the directors of the audited units the methods used to collect information relating to various domains and geographical areas, and consider whether or not these methods are in accordance with the current accounting standards and ensure that they are strictly applied. To realize this, auditors must consider sale turnover, charges of transfers between domains or geographical areas, elimination of amounts arising within a domain or area; comparisons with plans and other budget estimates, for example, the percentage of profits over sale turnover, and the allocation of assets and costs among segments in consistency with previous periods and the adequacy of the presentations in the financial statements when inconsistency exists. STANDARD 560 EVENTS OCCURRING AFTER THE DATE OF CLOSING ACCOUNTING BOOKS AND MAKING FINANCIAL STATEMENTS (Promulgated together with the Finance Minister's Decision No. 28/2003/QD-BTC of March 14, 2003) GENERAL PROVISIONS 01. The purpose of this standard is to prescribe the basic principles and procedures and guide the modes of application thereof to the responsibility of auditors and audit firms when considering events occurring after the date of closing accounting books and making financial statements for auditing in the process of auditing the financial statements. 02. Auditors must consider the effect of events occurring after the date of closing accounting books and making financial statements on the financial statements and the auditing reports. 03. This standard shall apply to the audit of financial statements and also to the audit of other financial information of audit firms. Auditors and audit firms must observe the provisions of this standard in the process of auditing financial statements. The audited units (clients) must possess necessary knowledge of this standard so that they can cooperate with auditors in supplying information and materials relating to the events occurring after the date of closing accounting books and making financial statements. The terms in this standard are construed as follows: 04. Events occurring after the date of closing accounting books and making financial statements mean events affecting the financial statements, which have occurred after the date of closing accounting books and making financial statements till the date of signing the auditing report; and events detected after the date of signing the auditing report. There are two kinds of events occurring after the date of closing accounting books and making financial statements: a/ Events that provide further evidences of the events that existed up to the date of closing accounting books and making financial statements; b/ Events that provide signs of events that arose after the date of closing accounting books and making financial statements. 05. The date of closing accounting books and making financial statements means the date lasting till the end of the last day of the accounting year. For example, if the accounting year spans from January 1 to December 31 of the calendar year, the date of closing accounting books and making financial statements lasts until the 24th hour of December 31 of such year. 06. The financial statement date means the date inscribed on a financial statement above the section reserved for the director's (or authorized person's) signature and the stamp of the audited unit. The financial statement date must be subsequent to the date of closing accounting books and making financial statements. 07. The date of signing the auditing report means the date inscribed on an auditing report above the section reserved for the auditor's signature, the director's (or authorized person's) signature and the stamp of the audit firm. The date of signing the auditing report may be either the date of actually signing the auditing report or the date when the audit work finishes at the audited unit. The audit firms must decide on their own the date of signing the auditing report which, however, must be subsequent to or coincide with the financial statement date. 08. The financial statement publicization date means the date of the postmark or the earliest date of signing for receipt of the financial statements and auditing reports which are submitted to the State bodies or publicized. CONTENTS OF THE STANDARD 09. Events occurring after the date of closing accounting books and making financial statements and relating to the responsibility of auditors and audit firms are classified into three stages: - Events occurring up to the date of signing the auditing report; - Events discovered after the date of signing the auditing report but before the financial statement publicization date; - Events discovered after the financial statement publicization date. Events occurring up to the date of signing the auditing report 10. Auditors must establish and perform audit procedures to gather sufficient appropriate audit evidences in order to determine all events occurring up to the date of signing the auditing report, which may affect the financial statements, and request the units to make adjustment of, or present explanations in, the financial statements. These procedures supplement routine procedures applied to special events occurring after the date of closing accounting books and making financial statements in order to collect further audit evidences regarding account balances at the time of making financial statements. However, auditors are not required to consider all matters on which previously applied procedures have provided satisfactory conclusions. For example, examining the sale of inventory and the settlement of debts after the date of closing accounting books would provide evidences regarding the value of inventory in the financial statements. 11. The procedures to identify events that may require the audited units to adjust the financial statements or present explanations therein should be performed at a time nearest to the date of signing the auditing report and normally include the following steps: + Reviewing procedures the units have prescribed to ensure that all events occurring after the date of closing accounting books and making financial statements are identified. + Reading minutes of the meetings of shareholders, the management boards, the Control Boards and the directorates held after the date of closing accounting books and making financial statements, and inquiring about matters discussed at these meetings but not recorded in the minutes. + Reading the units' financial statements of the latest period and the financial plans as well as other management reports of the directors. + Requesting the units or their lawyers to supply further information concerning the previously notified litigation and/or dispute cases or other litigation and dispute cases (if any). + Inquiring the units' directors to identify events which occur after the date of closing accounting books and making financial statements and may materially affect the financial statements, such as: - Data temporarily calculated or not yet confirmed; - Commitments, borrowings or guarantees, which have been recently entered into; - Sales of assets, which have been effected or are planned; - Newly issued shares or bonds; - Merger or dissolution agreements, which have been signed or are planned; - Assets which have been appropriated or destroyed due to fire or flood - Risks or contingencies; - Unusual accounting adjustments, which have been made or are planned; - Events which have occurred or are likely to occur and thereby render inappropriate the accounting policies already used for making financial statements. For example, the occurrence of bad debts would render invalid the presumption on the continuity of business activities. 12. Where a subordinate unit (a company's branch or a company under a corporation) is audited by another independent audit firm, auditors who audit the superior unit must consider the procedures applied by such audit firm's auditors to the events occurring after the date of closing accounting books and making financial statements and examine whether or not they need to inform such audit firm of the expected date of signing their auditing reports. 13. When recognizing that the events occurring after the date of closing accounting books and making financial statements materially affect the financial statements, auditors must determine whether these events are correctly calculated and properly presented in the audited financial statements. Events discovered after the date of signing the auditing report and before the financial statement publicization date 14. Auditors are not required to apply procedures or review matters relating to the financial statements after the date of signing the auditing report. The directors of the audited units shall, however, have to notify the auditors or audit firms of the events which have occurred after the date of signing the auditing report and before the financial statement publicization date and may affect the audited financial statements. 15. Where auditors become aware of an event which occurs after the date of signing the auditing report and before the financial statement publicization date and may materially affect the financial statements, they must consider whether or not the financial statements and auditing reports need to be amended and must discuss this matter with the audited units' directors so as to take appropriate measures in each particular circumstance. 16. Where, at the auditors' request, the directors of the audited units accept to amend the financial statements, the auditors shall perform necessary procedures suitable to the practical circumstances and then provide the audited units with a new report based on the amended financial statements. The new auditing report must be signed at the same date of the amended financial statements or at a later date. In this case, auditors must perform the audit procedures specified at paragraphs 10 and 11 till the date of signing the amended auditing report. 17. Where the directors of the audited units do not amend the financial statements as requested by auditors, and the auditing reports have not yet been sent to the audited units, the auditors and audit firms shall make a new auditing report expressing a partial acceptance opinion or non-acceptance opinion. 18. Where events which have a material effect on the financial statements are discovered only after the auditing reports have been sent to the audited units, the auditors shall request the heads of the audited units not to publicize the financial statements and the auditing reports to third parties. If the units still decide to publicize these reports, the auditors must apply appropriate measures to prevent the third parties from using their auditing reports. The preventive measures taken will depend on the auditors' legal powers and obligations as well as the recommendations of the auditors' lawyers. Events discovered after the financial statement publicization date 19. After the financial statements and the auditing reports have been publicized, auditors are not required to consider and examine any data or events relating to the audited financial statements. 20. After the financial statements and the auditing reports have been publicized, if auditors become aware of events which occurred up to the date of signing the auditing report and cause the auditors to modify the auditing reports, the auditors should consider whether the financial statements and the auditing reports need to be revised or not and must discuss this matter with the directors of the audited units and take appropriate measures in each particular circumstance. 21. Where the directors of the audited units accept to revise the financial statements, the auditors must carry out necessary appropriate procedures and review the measures taken by the audited units to ensure that any recipients of the financial statements and the auditing reports are informed of this matter. At the same time, the auditors and audit firms must publicize a new auditing report based on the revised financial statements. 22. The new auditing reports must contain a paragraph explaining the reasons for the revision of the previously publicized financial statements and auditing reports. The new auditing reports shall be signed at the same date of the revised financial statements or at a later date. In this case, auditors must perform the audit procedures specified at paragraphs 10 and 11 till the date of the revised auditing report. 23. Where the directors of the audited units do not notify the matter mentioned at paragraph 21 above to the recipients of the previously publicized financial statements and auditing reports nor revise the financial statements at the auditors' requests, the auditors and audit firms must notify the directors of the audited units of the measures to be taken by the auditors to prevent the third parties from using the auditing reports. The preventive measures taken will depend on the auditors' legal powers and obligations as well as the recommendations of the auditors' lawyers. 24. Where the financial statements for the following fiscal year are being audited by the audit firms and are bound to be publicized, it may not be necessary to revise the financial statements and auditing reports for the preceding fiscal year provided that the matter mentioned at paragraph 21 above is clearly described in the representations on the financial statements for the following year. Cases where the audited units issue securities 25. Where the audited units issue securities on the market, auditors must consider any law provisions relating to the securities issuance. For example, auditors may be required to carry out additional audit procedures till the date when the audited units post up securities issuance information. These procedures normally include measures specified at paragraphs 10 and 11 till the time of posting up information and reviewing documents on the posted information to ascertain that the posted information is consistent with the financial information already confirmed by the auditors. STANDARD No. 600 USE OF OTHER AUDITOR’S MATERIALS (Promulgated together with the Finance Minister's Decision No. 28/2003/QD-BTC of March 14, 2003) GENERAL PROVISIONS 01. The purpose of this standard is to prescribe the basic principles and procedures and guide the mode of application thereof to the use of other auditors' auditing materials regarding the financial information of one or many units when auditing the financial statements of a unit, including financial information of subordinate units and of other economic units. 02. When the principal auditors use the audit materials of other auditors, they must determine the extent of influence of such materials on their audits. 03. This standard shall apply to the audit of the financial statements of a unit, which include financial information of one or many subordinate units, and other economic units. This standard shall not apply to cases involving two or more auditors appointed as joint auditors for a unit, nor does it deal with the relationship between the present auditors and the previous year’s auditors. Where the principal auditors conclude that the financial statements of subordinate units and other economic units have an immaterial effect, this standard shall not apply, except where many units, though each having an immaterial effect, can together produce a material effect, the application of this standard should be considered. The audited units (clients), units and individuals related to the use of other auditors' materials by the principal auditors must possess necessary knowledge of the essential principles and procedures in this standard so that they can cooperate with the audit firms and the principal auditors in the auditing process. The terms in this standard are construed as follows: 04. Principal auditors mean the auditors with responsibility for auditing the financial statements and signing the auditing reports of units, including financial information of one or many subordinate units and other economic units audited by the other auditors. 05. Other auditors mean the auditors with responsibility for auditing the financial statements and signing the auditing reports of subordinate units or other economic units, which are included in the financial statements of the superior unit. Another auditor is the auditor working for another audit firm or for a branch or office of the audit firm. 06. Subordinate units mean units, components, branches, subsidiaries or member companies of the superior units, whose financial information is included in the superior units' financial statements audited by the principal auditors. 07. Other economic units mean units, joint-venture companies, associated companies with economic relations, whose financial information is included in the units' financial statements audited by the principal auditors. CONTENTS OF THE STANDARD Acceptance as principal auditors 08. To accept auditor contracts with the principal auditor's responsibility, auditors and audit firms must consider the following matters: + The materiality of the portion of the financial statements which the principal auditors audit; + The principal auditors' knowledge about the situation of business activities of the subordinate units and other economic units audited by the other auditors; + The risk of material errors in the financial statements of the subordinate units and other economic units audited by other auditors; + The possibility to perform additional procedures as prescribed in this standard, which relate to financial information of subordinate units and other economic units audited by other auditors with the participation of the principal auditors. Audit procedures performed by the principal auditors 09. When planning the audits involving the use of other auditor's materials, the principal auditors must consider the professional capability of the audit firms and other auditors in the context of their actual work. In order to consider professional capability of the audit firms and other auditors, the principal auditors must base themselves on the following sources of information: the audit organizations where the other auditors have made practice registration; colleagues of the other auditors; clients or people having working relations with the other auditors, or through face-to-face meetings with the other auditors. 10. The principal auditors should perform necessary procedures to obtain sufficient appropriate audit evidences that the other auditors' work is relevant to the principal auditors' audit work and purposes in each specific audit. 11. The principal auditors should advise the other auditors of: + The independence requirements related to the superior unit, subordinate units and other economic units and obtain written representations on compliance therewith + The use of the other auditors' materials and reports and the coordination between the two parties right at the audit planning stage; + Matters requiring special consideration; procedures for identification of internal transactions that need to be stated in written explanations, and the timetable for the audit; + The accounting, auditing and reporting requirements and obtain written representations on compliance therewith. 12. The principal auditors may discuss with the other auditors the audit procedures already applied by the latter or review the other auditors' audit dossiers. The performance of these audit procedures will depend on the specific context of the audit and on the principal auditors' assessment of the professional capability of the other auditors. 13. The principal auditors are not required to apply the procedures stated in paragraph 12 if they have sufficient appropriate audit evidences that the audit procedures performed by the other auditors are satisfactory and ensure the audit quality. 14. The principal auditors must consider the significant findings of the other auditors. 15. The principal auditors may discuss with the other auditors and the directors of the subordinate units and other economic units the significant findings or other matters affecting the financial statements of such units. When necessary, the principal auditors may perform additional procedures to check the records or financial statements of the subordinate units. Depending on the particular circumstances, these checking procedures may be performed by the principal auditors or the other auditors. 16. The principal auditors should archive in their audit dossiers documents relating to the financial statements of the subordinate units and other economic units audited by the other auditors; documents on the performance of audit procedures and conclusions reached therefrom; the names of the other auditors and any conclusions, though being immaterial, reached by the other auditors. Cooperation between auditors 17. The other auditors must cooperate with the principal auditors in cases the principal auditors use their auditing materials. For example, the other auditors must inform the principal auditors of any portions of their work that cannot be carried out as requested or of any matters significantly affecting the other auditors' work, which are of the principal auditors' concern. Similarly, the principal auditors should notify the other auditors of any matters which are discovered by the principal auditors and may considerably affect the financial statements of the subordinate units or other economic units audited by the other auditors. The cooperation between auditors should be agreed upon by the authorities managing the audits. Conclusions and elaboration of auditing reports 18. When the principal auditors conclude that the other auditors' materials cannot be used and they has not been able to perform additional audit procedures for the financial statements of the subordinate units and other economic units audited by the other auditors, if deeming that such would materially affect the audited financial statements, the principal auditors should express a partial acceptance opinion or an opinion to refuse to express an opinion because there is a limitation in the scope of the audit. 19. When the principal auditors have relied on the other auditors' opinions, their reports must clearly state this and specify the limitation of the financial statements audited by the other auditors. 20. Where the other auditors issue or plan to issue a modified auditing report, the principal auditors should consider the nature and significance of the modifications in relation to the financial statements audited by the principal auditors and determine whether their auditing reports need to be modified. Responsibility of the principal auditors 21. The principal auditors must observe the principles and procedures prescribed in this standard when auditing the financial statements of the superior units, which include financial information of the subordinate units and other economic units, and must be responsible for the financial statement audit risks.-
