See section 9339A for interpretations of this section.
Issue date, unless otherwise indicated: April 1, 1982.
.01
The auditor should prepare and maintain working papers, the form and content of which should be designed to meet the circ*mstances of a particular engagement. fn2 The information contained in working papers constitutes the principal record of the work that the auditor has done and the conclusions that he has reached concerning significant matters. fn3
Functions and Nature of Working Papers
.02
Working papers serve mainly to—
- Provide the principal support for the auditor's report, including his representation regarding observance of the standards of field work, which is implicit in the reference in his report to generally accepted auditing standards.
- Aid the auditor in the conduct and supervision of the audit.
.03
Working papers are records kept by the auditor of the procedures applied, the tests performed, the information obtained, and the pertinent conclusions reached in the engagement. Examples of working papers are audit programs, analyses, memoranda, letters of confirmation and representation, abstracts of company documents, and schedules or commentaries prepared or obtained by the auditor. Working papers also may be in the form of data stored on tapes, films, or other media.
.04
Factors affecting the auditor's judgment about the quantity, type, and content of the working papers for a particular engagement include (a) the nature of the engagement, (b) the nature of the auditor's report, (c) the nature of the financial statements, schedules, or other information on which the auditor is reporting, (d) the nature and condition of the client's records, (e) the assessed level of control risk, and (f) the needs in the particular circ*mstances for supervision and review of the work.
Content of Working Papers
.05
The quantity, type, and content of working papers vary with the circ*mstances (see paragraph .04), but they should be sufficient to show that the accounting records agree or reconcile with the financial statements or other information reported on and that the applicable standards of field work have been observed. Working papers ordinarily should include documentation showing that—
- The work has been adequately planned and supervised, indicating observance of the first standard of field work.
- A sufficient understanding of internal control has been obtained to plan the audit and to determine the nature, timing, and extent of tests to be performed.
- The audit evidence obtained, the auditing procedures applied, and the testing performed have provided sufficient competent evidential matter to afford a reasonable basis for an opinion, indicating observance of the third standard of field work.
Ownership and Custody of Working Papers
.06
Working papers are the property of the auditor, and some states have statutes that designate the auditor as the owner of the working papers. The auditor's rights of ownership, however, are subject to ethical limitations relating to the confidential relationship with clients.
.07
Certain of the auditor's working papers may sometimes serve as a useful reference source for his client, but the working papers should not be regarded as a part of, or a substitute for, the client's accounting records.
.08
The auditor should adopt reasonable procedures for safe custody of his working papers and should retain them for a period sufficient to meet the needs of his practice and to satisfy any pertinent legal requirements of records retention.
Effective Date
.09
This section is effective for engagements beginning after May 31, 1982.
