Introduction
这也是一个人1. The purpo of this International Standard on Assurance Engagements (ISAE)
is to establish basic principles and esntial procedures for, and to provide guidance to, professional accountants in public practice (for purpos of this ISAE referred to as “practitioners”) for the performance of assurance engagements other than audits or reviews of historical financial information covered by International Standards on Auditing (ISAs) or International Standards on Review Engagements (ISREs).
2.
This ISAE us the terms “reasonable assurance engagement” and “limited assurance engagement” to distinguish between the two types of assurance engagement a practitioner is permitted to perform. The objective of a reasonable assurance engagement is a reduction in assurance engagement risk to an acceptably low level in the circumstances of the engagement 1 as the basis for a positive form of expression of the practitioner’s conclusion. The objective of a limited assurance engagement is a reduction in assurance engagement risk to a level that is acceptable in the circumstances of the engagement, but where that risk is greater than for a reasonable assurance engagement, as the basis for a negative form of expression of the practitioner’s conclusion. Relationship with the Framework, Other ISAEs, ISAs and ISREs
3. The practitioner should comply with this ISAE and other relevant ISAEs
when performing an assurance engagement other than an audit or review of historical financial information covered by ISAs or ISREs. This ISAE is to be read in the context of the “International Framework for Assurance Engagements” (the Framework), which defines and describes the elements and objectives of an assurance engagement, and identifies tho engagements to which ISAEs apply. This ISAE has been written for general application to assurance engagements other than audits or reviews of historical financial information covered by ISAs or ISREs. Other ISAEs may relate to topics that apply to all subject matters or be subject matter specific. Although ISAs and ISREs do not apply to engagements covered by ISAEs, they may nevertheless provide guidance to practitioners.
1 Engagement circumstances include the terms of the engagement, including whether it is a reasonable
assurance engagement or a limited assurance engagement, the characteristics of the subject matter, the criteria to be ud, the needs of the intended urs, relevant characteristics of the responsible party and its environment, and other matters, for example events, transactions, conditions and practices, that may have a significant effect on the engagement.
ASSURANCE ENGAGEMENTS
Ethical Requirements
4.The practitioner should comply with the requirements of Parts A and B of
the IFAC Code of Ethics for Professional Accountants (the Code).
5.The Code provides a framework of principles that members of assurance
teams, firms and network firms u to identify threats to independence,2
evaluate the significance of tho threats and, if the threats are other than牢骚
clearly insignificant, identify and apply safeguards to eliminate the threats or
reduce them to an acceptable level, such that independence of mind and
independence in appearance are not compromid.
Quality Control
6.The practitioner should implement quality control procedures that are
applicable to the individual engagement. Under International Standard on
Quality Control (ISQC) 1, “Quality Control for Firms that Perform Audits and
Reviews of Historical Financial Information, and Other Assurance and Related
Services Engagements,”3 a firm of professional accountants has an obligation
to establish a system of quality control designed to provide it with reasonable
assurance that the firm and its personnel comply with professional standards
and regulatory and legal requirements, and that the assurance reports issued by
the firm or engagement partners are appropriate in the circumstances. In
addition, elements of quality control that are relevant to an individual
engagement include leadership responsibilities for quality on the engagement,
ethical requirements, acceptance and continuance of client relationships and
specific engagements, assignment of engagement teams, engagement
performance, and monitoring.
Engagement Acceptance and Continuance
7.The practitioner should accept (or continue where applicable) an
assurance engagement only if the subject matter is the responsibility of a
party other than the intended urs or the practitioner. As indicated in
paragraph 27 of the Framework, the responsible party can be one of the
intended urs, but not the only one. Acknowledgement by the responsible
2If a professional accountant not in public practice, for example an internal auditor, applies ISAEs, and
(a) the Framework or ISAEs are referred to in the professional accountant’s report; and (b) the
professional accountant or other members of the assurance team and, when applicable, the professional accountant’s employer, are not independent of the entity in respect of which the assurance engagement is being performed, the lack of independence and the nature of the relationship(s) with the assurance client are prominently disclod in the professional accountant’s report. Also, that report does not include the word “independent” in its title, and the purpo and urs of the report are restricted.
3ISQC 1, “Quality Control for Firms that Perform Audits and Reviews of Historical Financial Information, and Other Assurance and Related Services Engagements” was issued in February 2004.
Systems of quality control in compliance with ISQC 1 are required to be established by June 15, 2005. ISAE 3000 1046

party provides evidence that the appropriate relationship exists, and also establishes a basis for a co
mmon understanding of the responsibility of each party. A written acknowledgement is the most appropriate form of documenting the responsible party’s understanding. In the abnce of an acknowledgement of responsibility, the practitioner considers:
(a) Whether it is appropriate to accept the engagement. Accepting it may
be appropriate when, for example, other sources, such as legislation or
a contract, indicate responsibility; and
(b)
If the engagement is accepted, whether to disclo the circumstances
in the assurance report. 8. The practitioner should accept (or continue where applicable) an
assurance engagement only if, on the basis of a preliminary knowledge of the engagement circumstances, nothing comes to the attention of the practitioner to indicate that the requirements of the Code or of the ISAEs will not be satisfied. The practitioner considers the matters in paragraph 17 of the Framework and does not accept the engagement unless it exhibits all the characteristics requi
red in that paragraph. Also, if the party engaging the practitioner (the “engaging party”) is not the responsible party, the practitioner considers the effect of this on access to records, documentation and other information the practitioner may require to complete the engagement.
9.
The practitioner should accept (or continue where applicable) an assurance engagement only if the practitioner is satisfied that tho persons who are to perform the engagement collectively posss the necessary professional competencies. A practitioner may be requested to perform assurance engagements on a wide range of subject matters. Some subject matters may require specialized skills and knowledge beyond tho ordinarily possd by an individual practitioner (e paragraphs 26-32). Agreeing on the Terms of the Engagement
10. The practitioner should agree on the terms of the engagement with the
engaging party. To avoid misunderstandings, the agreed terms are recorded in an engagement letter or other suitable form of contract. If the engaging party is not the responsible party, the nature and content of an engagement letter or contract may vary. The existence of a legislative mandate may satisfy the requirement to agree on the terms of the engagement. Even in tho situations an engag
ement letter may be uful for both the practitioner and engaging party.
11. A practitioner should consider the appropriateness of a request, made before the completion of an assurance engagement, to change the engagement to a non-assurance engagement or from a reasonable assurance engagement to a limited assurance engagement, and should not
ASSURANCE ENGAGEMENTS
agree to a change without reasonable justification. A change in
circumstances that affects the intended urs’ requirements, or a
misunderstanding concerning the nature of the engagement, ordinarily will
justify a request for a change in the engagement. If such a change is made, the
practitioner does not disregard evidence that was obtained prior to the change. Planning and Performing the Engagement
12.The practitioner should plan the engagement so that it will be performed
effectively. Planning involves developing an overall strategy for the scope,
emphasis, timing and conduct of the engagement, and an engagement plan,
consisting of a detailed approach for the nature, timing and extent of evidence-
gathering procedures to be performed and the reasons for lecting them.
Adequate planning helps to devote appropriate attention to important areas of
the engagement, identify potential problems on a timely basis and properly
organize and manage the engagement in order for it to be performed in an
effective and efficient manner. Adequate planning also assists the practitioner
to properly assign work to engagement team members, and facilitates their
direction and supervision and the review of their work. Further, it assists,
where applicable, the coordination of work done by other practitioners and
experts. The nature and extent of planning activities will vary with the
engagement circumstances, for example the size and complexity of the entity
and the practitioner’s previous experience with it. Examples of the main
matters to be considered include:

•The terms of the engagement.塞子的拼音

•The engagement process and possible sources of evidence.
•The practitioner’s understanding of the entity and its environment, including the risks that the subject matter information may be materially

•Identification of intended urs and their needs, and consideration of materiality and the components of assurance engagement risk.
•Personnel and experti requirements, including the nature and extent of experts’ involvement.
13.Planning is not a discrete pha, but rather a continual and iterative process
throughout the engagement. As a result of unexpected events, changes in
conditions, or the evidence obtained from the results of evidence-gathering
procedures, the practitioner may need to revi the overall strategy and
engagement plan, and thereby the resulting planned nature, timing and extent

of professional skepticism recognizing that circumstances may exist that cau the subject matter in

formation to be materially misstated. An attitude of professional skepticism means the practitioner makes a critical asssment, with a questioning mind, of the validity of evidence obtained and is alert to evidence that contradicts or brings into question the reliability of documents or reprentations by the responsible party.
15. The practitioner should obtain an understanding of the subject matter and other engagement circumstances, sufficient to identify and asss the risks of the subject matter information being materially misstated, and sufficient to design and perform further evidence-gathering procedures. 16. Obtaining an understanding of the subject matter and other engagement circumstances is an esntial part of planning and performing an assurance engagement. That understanding provides the practitioner with a frame of reference for exercising professional judgment throughout the engagement, for example when:
•
Considering the characteristics of the subject matter; •
Asssing the suitability of criteria; • Identifying where special consideration may be necessary, for example
factors indicative of fraud, and the need for specialized skills or the work
of an expert;
西安市内必去景点大全• Establishing and evaluating the continued appropriateness of quantitative
materiality levels (where appropriate), and considering qualitative
materiality factors;
• Developing expectations for u when performing analytical procedures;
• Designing and performing further evidence-gathering procedures to
reduce assurance engagement risk to an appropriate level; and
•
Evaluating evidence, including the reasonableness of the responsible
party’s oral and written reprentations. 17. The practitioner us professional judgment to determine the extent of the
understanding required of the subject matter and other engagement circumstances. The practitioner considers whether the understanding is sufficient to asss the risks that the subject matter information may be materially misstated. The practitioner ordinarily has a lesr depth of understanding than the responsible party.
Asssing the Appropriateness of the Subject Matter
18. The practitioner should asss the appropriateness of the subject matter.
An appropriate subject matter has the characteristics listed in paragraph 33 of
