Preface
Today, audit working paper is not the strange terminology with the economists
because of their important role for the audit. Building is a complete working paper
systems which can be used for any company is a huge target for any public audit
Company. As the fact that, in 2014, AAC Audit Company has a changing in working
paper system for the new one, I think I should do a small development program one
hand learning about the importance of the audit working papers system and inn the
other hand contribute a small part of completing the AAC working system. With the
limited content, I will divide my article into 3 chapters

papers in auditing financial statements

The concept of financial audit.

1.1

Nature of audit

1.1.1 The demand for reliable information
As society becomes more complex, decision makers are more likely to face
with the information risk which lead the investors may make wrong decisions for their
investments. After scandal of Sabena Oxley, information risk becomes an emerging
issue which is concerned by all economists in the world.
According to “Audit and assurance services”, the information risk is: the
probability that the information circulated by a company will be false or misleading.
Client management has an incentive to make the business appear better than it actually
may be. This can create a conflict of interest between client management and
investors.
There are several reasons for information risk: remoteness of information,
biases and motives of the provider, voluminous data, and the existence of complex
exchange transactions.
Remoteness of Information: In a global economy, it is nearly impossible for a
decision maker to have much knowledge about the organization with which they do

business because decisions makers are not trained to collect, compile, and summarize
the key operating information themselves. They need to rely on the others which can
cause to intentionally or unintentionally misstated increases.
Biases and Motives of the Provider: If information is provided by someone
whose goals are inconsistent with those of the decision maker, the information may be
biased in favor of the provider.
Voluminous Data: organizations become larger accompanied by the volume of
their exchange transactions. This increases the likelihood that improperly recorded
information is included in the records perhaps hidden in a large amount of other
information. If many minor misstatements remain undiscovered, the combined total
can be significant.
Complex Exchange Transactions: In the past few decades, exchange
transactions between organizations have become increasingly complex and therefore
more difficult to record properly. For example, the correct accounting treatment of the
acquisition of one entity by another poses relatively difficult accounting problems.
Other examples include properly combining and disclosing the results of operations of
subsidiaries in different industries and properly disclosing derivative financial
instruments.

1.1.2 Reducing information risk and the rise of audit.
After comparing costs and benefits, business managers and financial statement

users may conclude that the best way to deal with information risk is simply to have it
remain reasonably high. A small company may find it less expensive to pay higher
interest costs than to increase the costs of reducing information risk.
For larger businesses, it is usually practical to incur costs to reduce information
risk. There are three main ways to do so.
User Verifies Information: The user may go to the business premises to
examine records and obtain information about the reliability of the statements.
Normally, this is impractical because of cost. In addition, it is economically inefficient
for all users to verify the information individually.
There are some users can perform their own verification such as the tax
department do this to reflect the actual tax due the government or the company use
auditors to verify and evaluate the information of potential child company in the
business acquisitions purpose.
User Shares Information Risk with Management: There is considerable legal
precedent indicating that management is responsible for providing reliable information
to users. If users rely on inaccurate financial statements and as a result incur a financial
loss, they may have a basis for a lawsuit against management. A difficulty with sharing
information risk with management is that users may not be able to collect on losses. If
a company is unable to repay a loan because of bankruptcy, it is unlikely that
management will have sufficient funds to repay users.
Audited Financial Statements Are Provided: The most common way for
users to obtain reliable information is to have an independent audit. Typically,
management of a private company or the audit committee for a public company
engages the auditor to provide assurances to users that the financial statements are
reliable.
Decision makers can then use the audited information on the assumption that it
is reasonably complete, accurate, and unbiased. The auditor work is valuable because
of the auditor’s independence from the client and knowledge of financial statement
reporting matters, and their checking expertise. This way is the most common way to
reduce the information risk and that is economics demand for auditing.

1.2 Audit Definition
According to auditing and assurance services fifth edition: Auditing is a
systematic process of objectively obtaining and evaluating evidence regarding
assertions about economic actions and events to ascertain the degree of
correspondence between the assertions and established criteria and communicating the
results to interested users.
Financial audit is a typical activity of the audit, with the specific objective is "to
express an opinion confirming that the financial statements have been prepared on the

basis of standards and current accounting regulations (or be acceptance), with related
legal compliance, there give a true and fair view, in all material respects or not
Audit Assertions are the implicit or explicit claims and representations made by
the management responsible for the preparation of financial statements regarding the
appropriateness of the various elements of financial statements and disclosures. The
financial audit assertions are about the trueness and fairness of the financial statement
(include the footnotes statement)
The established criteria is the common set of accounting principles, standards
and procedures that companies use to compile their financial statements. GAAP are a
combination of authoritative standards (set by policy boards) and simply the
commonly accepted ways of recording and reporting accounting information.
An external user is a person outside of an organization who does not directly

run its operations and uses financial or accounting information about that company to
make decisions. In other words, it’s someone who doesn’t manage or work for a
company but uses its financial information. The common external user is investors,
creditors
and
banks.

Audit documentation

2.1.1 Audit documentation definition

Student: Nguyễn Quang Trung

MAJOR THESIS

Supervisor: Phạm Kim Ngọc,M.A

With any audits, Evidence is obtained by the auditor to determine whether the
information being audited is stated in accordance with the established criteria. To
satisfy the purpose of the audit, auditors must obtain a sufficient quality and volume of

evidence. Auditors must determine the types and amount of evidence necessary and
evaluate whether the information corresponds to the established criteria. The auditors
need to storage this evidence and all the work they had done in the audit
documentation for audit purpose.
According to the Auditing Standards Number 230 Issued under Decision No
120/1999 / QD-BTC of September 27, 1999 of the Ministry of Finance stated: Audit
records are documents auditors established, collected, sorted, used and storage stored
in a certain order as evidence for one specific audit. Documents in the Audit
documentation is shown on paper, on film, photographs, informatics media or any
other storage media in accordance with current law
2.1.2 Types of Audit documentations
According to VSA 230, the audit documentation divided should be prepared
and arranged into: permanent audit documentation and current audit documentation
2.1.2.1. Permanent Audit documentation
VSA 230 defines general audit documentation as follows: Permanent audit files
is record contains general information about the client involves two or more audits
during the financial years of a client.
This files stored documents, schedules and other historical or continuous
information needed for many years. This profile provides a suitable source of
information about the client, service of current and future audits if contracts continue.
Continually updated information is also a problem should be noted with this
file. Permanent audit documentation is the useful tool for the audit. In some specific
case, Auditors only focus on complete the current audit documentation and they don’t
review and update the information of permanent audit files. This may lead to the
reducing of quality of this information because the information in it has become
outdated and often not usable anymore, leading to influence audit quality.
Thus, the examination and update documents in permanent audit files on a
regular basis are essential. Auditors should add new information and adjust old
information when client’s Company information has changed and they must specify
the changes in this file.

2.1.2.2 Curret audit documentation
VSA 230 has defined Current audit file as follows: "current audit
documentation is the file contain customer information relates only to audits of
financial year”
Annual audit records include documents provided by the customer, such as
financial documents, accounting, taxes, of state agencies and superiors concerning the
financial year; The minutes confirmed by stakeholders sent to. Besides, it include the

documents of auditor; Notes on content, program and scope of the audit procedures
performed and the results obtained; The audit report, management letter and other
reports; The correspondence with other auditors, experts and other stakeholders;…
2.1.3 The role and meaning of audit documentation
Audit documentation has collected all information relevant to their audit clients
to serve their audit work as:
+ Storing the evidence collected by performed auditor as basis for an opinion of
auditors:
The information about the customer as well as the object audit fully updated
and supplemented continuously throughout the audit process to ensure adequate basis
for forming auditors audit opinion. This evidence obtained ensure the opinions of
auditor are base on the reliable, quality assurance of audit
+ Help for planning and performing the audit.

Normally, an audit is taking place by two or three auditors above in the certain
time period. They need audit plan to divide work and forming structure of the entitle
audit to conduct the audit efficiently. To get a appropriate plan for the current year, the
auditor must consult the information about the client (with the new client) and refer the
previous audit documentation (with the old one).
+ Help for inspection, review and evaluate the quality of the audit:
All documents, information and evidence collected are storing in the audit
documentation. Chief audit team checked the working paper and request explanations
of subordinates before giving up a higher level for approval. This is the basis for the
inspectors to understand the entire contents of the audit as well as oversight the work
of subordinate thus it also increases the quality of audit.
+ Help for the treatment of arising after the audit:
The occurrence of conflicts and litigation, as well as quality test of Association
practice and the Ministry of Finance is inevitable. Then audit documentation is
important legal evidence help auditors solve the problems that arise after the audit. It
can prove that audit was planned well, fully supervised, progress operating in
accordance with auditing standards. With audit evidence collected valuable, complete,
timely and audit reports were correct evaluation of audit results, audit file would
minimize audit risk may occur. On the other hand the audit files also the information
that helpful for future audits.
2.2 Working papers
2.2.1 Working papers definition
2.2.1.1. What are working papers:
“Working papers “are the written record of the basis for the auditor's
conclusions that provides the support for the auditor's representations, whether those
representations are contained in the auditor's report or otherwise. Audit working
papers also facilitates the planning, performance, and supervision of the engagement,

MAJOR THESIS

Supervisor: Phạm Kim Ngọc,M.A

and is the basis for the review of the quality of the work because it provides the
reviewer with written documentation of the evidence supporting the auditor's
significant conclusions. Among other things, working papers include records of the
planning and performance of the work, the procedures performed, evidence obtained,
and conclusions reached by the auditor.
It may be in the form of data stored on the paper, film, electronic media, or
other media. They can also be used in court e.g. in case of negligent audit.
Working papers are reviewed by members of the engagement team performing
the work and might be reviewed by others for different purposes. Reviewers might
include, for example:
+ Auditors who are new to an engagement and review the prior year's
documentation to understand the work performed as an aid in planning and performing
the current engagement.
+ Supervisory personnel who review documentation prepared by other
members of the engagement team.
+ Engagement supervisors and engagement quality reviewers who review
documentation to understand how the engagement team reached significant
conclusions and whether there is adequate evidential support for those conclusions.
+A successor auditor who reviews a predecessor auditor's audit documentation.
+ Internal and external inspection teams that review documentation to assess
audit quality and compliance with auditing and related professional practice standards;
applicable laws, rules, and regulations; and the auditor's own quality control policies.
+ Others, including advisors engaged by the audit committee or representatives

of a party to an acquisition
2.2.1.2 Reason in preparing working papers:
+ This is basis for planning the audit.
+ Working papers record the evidence accumulated and the results of the audit
tests
+ Working papers have data for determining the proper type of audit report
+ Basis for review by supervisors and partners
+ Evidence audit works being performed in accordance with approved auditing
standards.
2.2.1.3 Purpose of audit working paper
Working papers are the evidence of work done by the auditor, he should prepare
working paper in order to provide evidence that audit was properly performed
according to ISA Standards. Working papers support auditor, in case he is being sue in
court by the client, for negligence of audit work.
+ Assist in the planning and performance of the audit
+ Assist in the supervision and review of audit work

Student: Nguyễn Quang Trung

Supervisor: Phạm Kim Ngọc,M.A

+ Recorded the audit evidence resulting from the audit work performed to
support the auditor’s opinion
2.2.1.4 Purposes served by working papers
1. Audit working papers serve four major purposes:

A. They constitute a permanent record of the objectives and scope of the
audit, as well as the work performed during the audit. Work papers organize and
coordinate all phases of the audit.
B.
They contain the back-up material in support of the audit findings
conclusions, opinions, and comments.
C.
They contain the basic material from which the audit report is prepared.
D. They reflect the quality and reliability of the work performed by the
auditor and substantiates and explain in detail the opinions and findings presented to
University management.
2. Working papers have a number of additional uses both during and after the
audit. These are to control audit progress by showing the auditor what audit
procedures have been completes and what audit procedures have not been
completed.
Working papers also provide:
+ A basis for study of patterns and trends.
+ Aid in the internal audit staff’s professional development.
+Detail supporting material for use in discussion with operating personnel.
+A source of evidence in litigation and in administrative actions.
+A basis for supervisory review and evaluation of audit performance
+A permanent record for use in planning and carrying out future audits.
+Demonstrate the auditors have complied with the Standards for the
Professional Practice of Internal Auditors
2.2.1.5 Function of audit working paper.
Helpful in making dentine audit report
Working papers are used for making denuine audit report. Without knowing the
reality of different facts which are written in working papers, auditor cannot make
audit report which shows accurate view of company’s financial statements.
Uses as evidence

Sometime, any party may behave like a neglect person, at that time; these
working papers will become the evidence of reported facts.
Direction to auditing procedure
Working papers are also good guide to direct the audit procedure. If auditor
wants to do audit work step by step, he should collect all working papers which are
required for auditing and set it according to the steps of auditing. Doing this, audit
work may be easy.
Check the weakness of internal control

MAJOR THESIS

Supervisor: Phạm Kim Ngọc,M.A

With the help of this tool, auditor can check the weak points of internal control
and suggest improving it.
2.2.1.6 Ownership of working papers:
The working papers prepared during the engagement, including those prepared
by the client for the auditor, are the property of the auditor. The only time anyone else,
including the client, has a legal right to examine the papers is limited specified
situations mentioned in ISA 230 Documentation and required by law, the examples are
court order, for public intersest and so on
Ordinarily, working papers can be provided to someone else only with the
express permission of the client. This is the case even if a CPA sells his practice to
another CPA firm.
2.2.2 Content of Audit working papers.

2.2.2.1 Each audit working paper must be headed with the following information:
+The name of the client
+The period covered by the audit
+The subject matter
+The file reference (4)
+The initials (signature) of the member of staff who prepared the working
paper, and the date on which it was prepared
+In the case of audit papers prepared by client staff, the date the working papers
were received, and the initials of the audit team member who carried out the audit
work
+The initials of the member of staff who reviewed the working papers and the
date on which the review was carried out
Each audit paper should meet the characteristics of a good working paper, as
detailed later in this article.
2.2.2.2The content of working papers
Main content presented on paper work of each object audit includes auditing
purposes, the source data, the audit scope, the work carried out, the audit results and
conclusions drawn.

Audit objectives
This section tells us why the auditor performing these audit work and what they
want to achieve is what.

The sources of data
This section tells us what are the sources of information that auditors use to
complete their working papers. The auditor should clearly note the information is
taken from what sources (ledger, diaries, invoices…), where to store this document (if
necessary), department or person responsible for the audit (if necessary), data forming
unit (if necessary).
For source data which is printed from a computer system, the auditors need to

Student: Nguyễn Quang Trung

Page 11


MAJOR THESIS

Supervisor: Phạm Kim Ngọc,M.A

specify the date printed. For data sources used on the computer, the auditor is required
to indicate the source, content, usage and file reference number used. This remark is
the basic for access to data when necessary. Auditors should provide full details on the
data sources in order to help other auditors could find information stored on paper
work

The Audit scope
This section tells us that the scope of information collected and the scope of the
audit was conducted. It provides some information such as some elements of the
sample is chosen, the conditions for sampling or audited accounting period

The Outlined work
Auditors should record all work carried out for each item during the audit on
paper work. This is the basis for the auditor concluded the audit and set up the audit
report later

Audit results
This section gives the results of each audit evidence obtained during the audit
through comparing 0the audit data compared with figures on financial statements. The
audit results are shown clearly on paper work. If not, the auditor should provide more

detailed description of the results obtained, attach with these analysis and discussion.

The Final conclusion of each part
This section tells us that the auditor's conclusion drawn by relying on these
audit results above. This is the most important part because conclusions will help
accomplish the goals that the auditors stated in the working paper
2.2.2.3 PAPERS PREPARED BY CLIENT
Certain working papers required by the auditor may have already been prepared
by client staff. The auditor should make arrangements, whenever possible, for copies
of these to be made available to the audit team. If client staff prepares working papers
which are to be retained by the auditor, the auditor should agree the form of the
working papers with client staff at an early stage in the audit, and include this
information in the audit timetable.
When arranging for working papers to be prepared, the auditor should take care
to ensure that the working papers will give all the information required. All such
working papers should normally be clearly identified as having been prepared by the
client. The member of audit staff directly responsible for an audit area in which
working papers prepared by client staff are included should sign those papers – this
will show that they have been checked and that they can be reviewed by the manager
and the partner, and by subsequent reviewers. The signature of the audit team member
indicates that the working paper (prepared by client staff) has been ‘audited’.
2.2.2.4 SOME CHARACTERISTICS OF A GOOD WORKING PAPER
On the basis of the discussion above, a good working paper should meet the
requirements of ISA 230 by displaying the following characteristics:
Student: Nguyễn Quang Trung

Page 12


MAJOR THESIS

Supervisor: Phạm Kim Ngọc,M.A

+ It should state a clear audit objective, usually in terms of an audit assertion
(for example, ‘to ensure the completeness of trade creditors’).
+ It should fully state the year/period end (eg 31 October 2006), so that the
working paper is not confused with documentation belonging to a different
year/period.
+ It should state the full extent of the test (ie how many items were tested and
how this number was determined). This will enable the preparer, and any subsequent
reviewers, to determine the sufficiency of the audit evidence provided by the working
paper.
+ Where there is necessary reference to another working paper, the full
reference of that other working paper must be given. A statement that details of testing
can be found on ‘another working paper’ is insufficient.
+ The working paper should clearly and objectively state the results of the test,
without bias, and based on the facts documented.
+ The conclusions reached should be consistent with the results of the test and
should be able to withstand independent scrutiny.
+ The working paper should be clearly referenced so that it can be filed
appropriately and found easily when required at a later date.
+ It should be signed by the person who prepares it so that queries can be
directed to the appropriate person.
+ It should be signed and dated by any person who reviews it, in order to meet
the quality control requirements of the review.
+ The reviewer of audit working papers should ensure that every paper has
these characteristics. If any relevant characteristic is judged absent, then this should
result in an audit review point (ie a comment by the reviewer directing the original
preparer to rectify the fault on the working paper).
+ In the paper work, auditors may use some symbols to express the content of

work. The notation used in the paper work to be defined uniformly as follows:

2.2.2.5 AVOIDING UNNECESSARY PAPERS
Before deciding to prepare a particular audit working paper, the auditor should
be satisfied that it is:
Necessary either because it will serve an essential or useful purpose in
support of the auditor’s report, or because it will provide information needed for tax or
other client-related statutory/regulatory purposes.
Not practicable for the client staff to prepare the working paper, or for
the auditor to make copies of papers that the client staff (including internal auditors)
have prepared as part of their normal regular duties.
2.2.3 Importance of working papers
+ Quality control purpose in respect of the audit
+ Assurance that the work delegated by the audit partner has been properly
completed
+ Evidence: the effective audit has been carried out
+ 3Es: increase the economy, efficiency and effectiveness of the audit
+ Support auditor conclusion: contain sufficiently detailed and up to date facts
with justify the reasonableness of the auditor’s conclusions.\

+ Future audits: retain a record of matters of continuing significance to future

audits.
2.2.3.1 Importance of Working papers
1. Working papers are instruments vital to the successful accomplishment of
all audit assignments performed. The working papers provide documented evidence of
an examination and evaluation and provide a connecting link between the work which
is performed and the final audit report. Hence, their importance cannot be overly
emphasized.
2. To a major extent, every auditor is judged by his skill and ability in
preparing working papers. When working papers are prepared in good form with
proper attention to layout, design, and legibility, with complete headings, explanations
of sources, and verification of work performed, they create a feeling of confidence in
the ability of staff member. Working papers should always make an impression of
system and order and conscientious attention to detail, coupled with a clear distinction
between the important and trivial
3. Another test of good working papers occurs when it is necessary for one
staff member to leave a partially completed assignment and turn it over to another staff
member. Ig the latter can proceed without confusion the working papers have stood the
critical test of being able to stand on their own
4. Every auditor will be expected to continuously strive for the highest
standards of excellence in the preparation of working papers.
2.2.4 Review of working paper
2.2.4.1 Review of working paper
Checking working papers is a very stage because of the benefits it brings to the audit.
Those are
+ It ensures the audit works is taking place properly, matching with the audit
procedure outlined.
+ Checking working papers is also confirm again the evidences collected and
the analysis to reinforce the final conclusions
+ It’s also confirm the exchange records with the client to reconfirm the client’s
conflict had solve and the audit works had completed

Working papers are checked by the team of senior auditors when the lower
levels completed their audits work in the working papers. The examination of paper
work is done through many levels; it could be two levels with the second level made
by the other senior auditor other when the audit end, or it could be three levels with the
