AUDIT EVIDENCEAudit RiskAttributes of Audit Evidence

Audit Risk

• The possibility that the auditors may unknowingly fail to appropriately modify their opinion on financial statements that are materially misstated• This is the risk that the auditors will issue an unqualified opinion on financial statements that contain a material departure from GAAP.

• Auditors must obtain sufficient appropriate audit evidence to reduce audit risk to a low level in every audit.

Audit Risk Risk of Material Risk That the Audit Risk = Misstatement * Auditors Fail

to Detect Misstatement

= Inherent Control Detection Risk * Risk * Risk

• Inherent Risk--Risk of a material misstatement occurring in an assertion assuming no related internal controls.

• Control Risk--Risk that a material misstatement in an assertion will not be prevented or detected on a timely basis by the company’s internal control.

• Detection Risk--Risk that the auditors’ procedures will lead them to conclude that a material misstatement does not exist in an assertion when in fact such misstatement does exist.

Audit Risk

Audit Evidence Concept

PSA 500 (Redrafted), par. 6 “Audit Evidence”

The auditor shall design and perform audit procedures that are appropriate in the circumstances for the purpose of obtaining sufficient appropriate audit evidence.

What Constitutes the Evidence

•Accounting records•Corroborating Information

Entity’s accounting records alone cannot be considered sufficient evidence to support an opinion on the financial statements. When auditing financial statements, the auditor should go beyond the accounting records. Auditor should obtain other corroborative information to support his opinion.

Attributes of Audit Evidence

Reasonable assurance is attained when the auditor has obtained sufficient appropriate evidence to reduce audit risk to an acceptable level. Audit evidence is typically obtained by performing risk assessment procedures, tests of control and substantive test.

3rd Standard of Fieldwork

•“Sufficient competent evidential matter”

•Competence stems from nature of evidence

•Sufficiency stems from extent of testing

The Third Field Work Standard

• Third standard of field work:• The auditor must obtain sufficient appropriate audit evidence by performing audit procedures to perform a reasonable basis for an opinion regarding the financial statements under audit

• Sufficient audit evidence• The quantity of audit evidence that must be obtained

Evaluation of Sufficiency

Factors to be considered: The competence of evidence The materiality of the item being

examined The risk involved in a particular

account Experience gained during previous

audits

Appropriateness of Audit Evidence

To be appropriate audit evidence must be:•Relevant•Reliable

Appropriateness of Audit Evidence• Principles: Audit evidence is ordinarily more reliable when it is:

• Obtained from knowledgeable independent sources outside the company rather than dependent sources

• Generated internally through a system of effective controls rather than ineffective controls.

• Obtained directly by the auditor rather than indirectly or by inference

• Documentary in form rather than oral• Provided by original documents rather than copies

Reliability of Certain Types of Audit Evidence

RELIABILITY TYPE EXAMPLE High Physical Inventory Observation

DocumentaryExternal Cutoff Bank StatementExternal/Internal Purchase InvoiceInternal Sales Invoice

Low Client Representations Management Representation Letter

Cost Benefit Consideration

•As a guiding rule, there should be a rational relationship between the cost of obtaining evidence and the usefulness of the evidence obtained. The auditor uses his professional judgment in determining the appropriate type of evidence that should be obtained.

Cost / Benefit of Evidence• Expensive Tests

• Physical examination• Confirmation

• Inexpensive tests• Observation• Inquiry• Reperformance

Evaluation of Audit Evidence• The auditor ordinarily obtains more assurance from consistent audit evidence obtained from different sources or of different nature than from items of audit evidence considered individually.

• In addition, obtaining audit evidence from different sources or of a different nature may indicate that an individual item of audit evidence is not reliable.

Overall Types of Audit Procedures

• Risk assessment procedures• To obtain an understanding of the client and its

environment, including its internal control, to assess the risks of material misstatement

• Further Audit Procedures• Tests of controls

• When appropriate, to test the operating effectiveness of controls in preventing material misstatements

• Substantive procedures• To detect material misstatements at relevant

assertion level. Substantive procedures include (a) analytical procedures, (b) tests of details of account balances, transactions and disclosures

AUDIT PROCEDURESAnalytical ProceduresEnquiry/ConfirmationInquiryObservationRecalcUlation/Reperformance

Relationship Among Assertions, Objectives and Procedures

•Financial Statements Assertions-Are representations made by the management explicit or otherwise embodied in the financial statement components

Assertions used by the auditor fall into the following categories:

• a. Assertions about classes of transactions and events for the period under audit:

• b. Assertions about account balances at the period end:

• c. Assertions about presentation and disclosure:

Relationship Among Assertions, Objectives and Procedures

• Objectives• Identify the standards for good evidence, the methods for obtaining and presenting the audit evidence.

• Audit Procedure• are acts or methods used to gather the validity of the assertions.

Using Assertion to Determine the Audit Procedure to be performed

• The auditor should:• should use assertions for classes of transactions, account balances and presentation and disclosures in sufficient detail to form a basis for the assessment of risks of material statement

• identify first their audit objectives or goals for each financial statement assertions; and

• then identify the audit procedures to fulfill that objective

Example of assertion and audit objectives

Table 1. Audit objectives for debtors and related transaction classes

Assertion category

Transaction class audit objectives

Account balance audit objectives

Existenceor occurrence

Recorded sales transactions represent goods shipped during the period. Recorded cash receipts transactions represent cash received during the period.

Debtors represent amounts owed by customers at the balance sheet date.

Completeness All sales and cash receipts transactions that occurred during the period have been recorded.

Debtors include all claims on customers at the balance sheet date.

Nature, Timing and Extent of Procedures

Timing• Refers to when audit procedures are performed or the period or date to which the audit evidence appliesExtent

• Includes the quantity of a specific audit procedure to be performedEffect of E-commerce

• Audit evidence is increasingly in electronic form.• Auditors must evaluate how electronic information affects their ability to gather evidence.

• Auditors use computers to read and examine evidence.

Audit Procedures for Obtaining Audit Evidence

Audit Procedure According to Purposea. Obtain an understanding of the entity and its environment, including its internal control, to assess the risks of material misstatement at the financial statement and relevant assertion levels ( risk assessment procedures);

b. When necessary, or when the auditor has determined to do so, test the operating effectiveness of controls in preventing or detecting material misstatements at the relevant assertion level (tests of controls)

c. Detect material misstatements at the relevant assertion level ( substantive procedures).

Audit Procedure According to Nature

•Inspection of Records or Documents• Inspection involves examining records or documents, whether internal or external, in paper form, electronic form, or other media, or physically examining an asset.

Types of Documents

Internal Documents• Prepared and used within client company. • Does not go outside the client.

External Documents• Document has been in hands of an outside party to the transaction.

• More reliable than internal documents.

Inspection of Tangible Assets• Inspection of tangible assets consists of physical examination of the assets.

• Inspection of tangible assets may provide appropriate audit evidence with respect to their existence, but not necessarily about the entity's rights and obligations or the valuation of the assets.

• Different from examining documentation is that the asset has inherent value.

•Direction of the Test• is important in establishing the assertion being tested by a certain procedure.

VOUCHING TRACING

-Examination of documents that support a recorded transaction or amount.-The direction of testing must be from the recorded item to the supporting document.-Tests existence or occurrence

Recorded Item to Supporting Document

-The primary test for unrecorded items and therefore tests the completeness assertion.-The direction of testing must be from the supporting document to the recorded item.

Supporting Document to Recorded Item

• Observation consists of looking at a process or procedure being performed by others.

• Auditor witnesses the physical activities of the client.

• Differs from physical examination because physical examination counts assets, while observation focuses on client activities.

• Useful in obtaining evidence that controls which leave no documentary evidence of application or existence are in operation.

Observation

Inquiry

• Inquiry consists of seeking information from knowledgeable persons in financial or nonfinancial roles within the company or outside the company.

•Auditor obtains information from the client in response to questions.

Recalculation

•Recalculation consists of checking the mathematical accuracy of documents or records.

Reperformance

•Reperformance is the auditor's independent execution of procedures or controls that were originally performed as part of the entity's internal control, either manually or through the use of Computer Assisted Audit Technique

Analytical Procedures• Analytical procedures consist of evaluations of financial information made by a study of plausible relationships among both financial and nonfinancial data.

• Auditors study relationships among data.• Unusual fluctuations occur when significant difference are not expected but do exist or when significant differences are expected but do not exist.

• Required during the planning stage.

Confirmation

•a specific type of inquiry, is the process of obtaining a representation of information or of an existing condition directly from a third party.

Owners’ Equity Shares outstanding Registrar and transfer agent

Other InformationInsurance coverage Insurance co.Contingent liabilities Bank, lender, and clients

legal counsel

External Confirmation

External Confirmation is the process of obtaining and evaluating audit evidence through a representation of information or an existing condition directly from a third party in response to a request for information about a particular item affecting assertions in the financial statements.

•Positive•Negative

Two Kinds of Confirmation

Positive Confirmations

- asks for response even if balance is correct.- request asks the respondent to reply to the auditor in all cases either by indicating the respondent's agreement with the given information- or by asking the respondent to fill in information- ordinarily expected to provide reliable audit evidence however there is a risk may reply to the request without verifying the information- may result to lower response rates

Negative Confirmations

• asks for a response only if balance is incorrect.

• uncertainty associated with no response.

• respondents reply only in the event of disagreement with the information provided in the request

• ordinarily provides less reliable audit evidence

Management Request Not to Confirm Information

The auditor should•consider whether there are valid grounds for such request: and

•obtain audit evidence to support the validity of management requests

Auditor’s Decision on the Management’s Request not to seek External Confirmations

The auditor Accepts the Request

the auditor should - Apply alternative audit procedures to obtain sufficient appropriate audit evidence

The auditor does not accept -There is a limitation of scope- The auditor should consider the possible effect on the auditor’s report.

Auditor ControlThe auditor should maintain control:• on the process of selecting people to whom request will be sent

• preparation and sending information requests

• responses to those requests

Substantive TestChapter 10

Purpose• To substantiate account balances• To detect material misstatements that

have passed through the accounting/internal control system filter.

Substantive tests are audit procedures designed to test for errors or irregularities

directly affecting the Monetary correctness of financial statement assertions.

Procedures to Reduce RiskControl Risk

• Procedures to gain an understanding of

internal control• Tests of controls

Detection Risk• Substantive tests of

transactions• Analytical procedures

• Tests of details of balances

TAKE NOTE: • Stronger controls will allow the auditor to

assess control risk below the maximum.• The more evidence an auditor collects from

the Substantive Tests, the lower the detection risk. Detection risk must be lower when control risk is higher. (Inverse Relationship)

URBN LOFTSConsideration: Early Substantive Tests

Chapter 10

• Early Substantive Testing is applicable when the auditor has assessed low control risk for that period. • The auditor may sometimes consider

applying tests of controls while extending his substantive procedures.

• In situations of actual or expected fraud, auditor may prefer applying substantive procedures at period end.

• There should be an ALLOWANCE for SIGNIFICANT CHANGES.

FRAUD AND ERROR

FRAUD AND ERRORERRORunintentional misstatement in financial statements, • Misinterpretatio

n of an accounting estimate

• Omission of amount

FRAUDintentional misstatementsresulting from:

1. Management Fraud

2. Employee Fraud

Two types of intentional misstatements

1. Management Fraud/Fraudulent Financial Reporting – fraud involving one or more members of management or those charged with governance

2. Employee Fraud - fraud involving only employees of entity“

Fraud, whether fraudulent financial reporting or misappropriation of assets, involves:• Incentive or pressure to

commit fraud• Perceived opportunity to do so• Rationalization of the act.

For example:

(a) Incentive or pressure to commit fraudulent financial reporting may exist when management is under pressure, from sources outside or inside the entity, to achieve an expected earnings target or financial outcome.

(b) A perceived opportunity to commit fraud may exist when an individual believes internal control can be overridden.

(c) Individuals may be able to rationalize committing a fraudulent act.

PrimaryRESPONSIBILITIES

Management/Governance

Auditor

prevention and detection of fraud

obtaining reasonable assurance that the

financial statements taken as a whole are

free from material misstatement,

whether caused by fraud or error.

INHERENT LIMITATIONS OF AUDIT

The risk of not detecting a material misstatement resulting from fraud is higher than the risk of not detecting one resulting from error.

The auditor’s ability to detect a fraud depends on factors such as:

1.skillfulness of the perpetrator2.the frequency and extent of manipulation3.the degree of collusion involved4.the relative size of individual amounts manipulated,5.the seniority of those individuals involved.

TAKE NOTE:The risk of the auditor not detecting a material misstatement resulting from management fraud is greater than for employee fraud.

PROFESSIONAL SKEPTICISM• Attitude of questioning mindThis enables the auditor to identify/evaluate:(1) matters that increase the risk of material

misstatement(2) circumstances that make the auditor

suspect that financial statements are materially misstated

(3) evidence obtained that brings into question the reliability of management representations.

FRAUD RISK FACTORS• events or conditions that indicate

an:• Incentive or pressure commit

fraud• Opportunity to commit fraud• Attitudes/Rationalizations

• Uses professional judgment.

Fraud risk factors

EFFECT

Inherent and

Control Risk

TAKE NOTE:The size, complexity, and ownership characteristics of the entity have a significant influence on the consideration of relevant fraud risk factors.

EX: Circumstances indicative of fraud 1. Discrepancies in the accounting records • Unauthorized balances/transactions

• Last-minute significant adjustments

2. Conflicting or missing evidence, • Missing documents. • Likely altered documents

3. Unusual relationships between the auditor and management

• Denial of access to records• Undue time pressures

Actions to be taken related to Fraud and Error:1. Identify if there are circumstances that indicate a possible misstatement in the financial statements.2. Determine whether statements are materially misstated.

3. If misstatements are identified, the auditor should consider whether such misstatement may be indicative of fraud.4. In evaluating and disposing of misstatements, consider materiality.

5. The auditor should document: (1) Fraud risk factors identified as being present during the risk assessment process and during the performance of audit; (2) the auditor’s responses to the fraud risk factors.

COMMUNICATIONMatters to communicate:1. Management competence and

integrity.2. Management Fraud3. Material Misstatements from:

• Error• Material weakness in internal

control• Future effect on Financial

Statements

To WHOM to REPORT:

•To Management•To Those Charged With Governance •To Regulatory and Enforcement Authorities

Auditor Unable to Continue the Engagement(a)Determine the professional and legal

responsibilities(b)Consider whether it is appropriate to

withdraw from the engagement(c) If the auditor withdraws:• Discuss with the appropriate level of

management/governance the auditor’s withdrawal

• Determine whether there is a professional or legal requirement to report

AUDITING ACCOUNTING ESTIMATES

Accounting Estimates • an approximation of the

monetary amount in the absence of a precise means of measurement.

Example:

•Allowance for doubtful accounts•Inventory obsolescence•Warranty obligations•Depreciation•Impairment loss•Fair value determination

Responsibility

Management Auditor

making accounting estimates

obtain sufficient appropriate evidence as to whether accounting

estimate is properly accounted for and

disclosed and accounting estimate is reasonable in

the circumstances

Risk or material misstatement is greater when estimation of uncertainty is based on assumptions 1. accounting estimates

relating to the outcome of litigation

2. fair value estimates of financial instruments that are not publicly traded

When assessing the risk of material misstatement relating to accounting estimates, the auditor should:1. understand the degree of

uncertainty involved the requirement of the standards

2. the procedures used by the client in making these estimates

When evaluating the reasonableness of accounting estimates, the auditor should :1.obtain an understanding of the procedures and methods including the accounting 2.internal control system used by management in making accounting estimates

In evaluating estimates, the auditor may use these approaches:1. Review and test the process

used by management to develop the estimate

2. Making independent estimate

3. Reviewing subsequent events which confirm estimate made.

Case where only disclosure required by generally accepted accounting principle is necessary:

•Some estimates, such as a potential loss from litigation, (because there are no relevant historical data or transaction in subsequent period).

AUDIT DOCUMENTATIONAudit Working Papers

Audit Documentation &Working PapersAudit documentation

• the principal record of the basis for the auditor’s conclusions

• principal support for the representations in the auditor’s report.

• includes records on the planning and performance of the work, the procedures performed, evidence obtained, and conclusions reached by the auditor.

“Documentation means the material (working papers) prepared by and for, or obtained and retained by the auditor in connection with the performance of the audit. Working papers may be in the form of data stored on paper, film, electronic media or other media.” PSA 230

Working Papers• A direct aid in the planning,

performance, and supervision of the audit;

• Record the audit evidence• Assist in review of the audit work.• Provide proof of the adequacy of the

audit

Significant Matters

• PSA 230 states: “The auditor should record in the working papers information on planning the audit, the nature, timing and extent of the audit procedures performed and the results thereof, and the conclusions drawn from the audit evidence obtained.”

• The auditor must document significant findings or issues, actions taken to address them (including additional evidence obtained), and the basis for the conclusions reached.

Form and Content of the Working Papers

• Audit documentation must contain sufficient information to enable an experienced auditor, having no previous connection with the engagement

• Convey the auditor’s reasoning on all matters which require the exercise of judgment and the auditor’s conclusions. (Professional Judgment)

Sales ordering and Invoicing

Each customer has a unique customer account number and this is used to enter sales orders when they are received in writing from customers. The orders are entered by an order clerk and the system automatically checks that the goods are available and that the order will not take the customer over their credit limit. For new customers, a sales manager completes a credit application; this is checked through a credit agency and a credit limit entered into the system by the credit controller. The company has a price list, which is updated twice a year. Larger customers are entitled to a discount; this is agreed by the sales director and set up within the customer master file.

FRAUDDuring the year a material fraud was uncovered. It involved cash/cheque receipts from customers being diverted into employees’ personal accounts. In order to cover up the fraud, receipts from subsequent unrelated customers would then be recorded against the earlier outstanding receivable balances and this cycle of fraud would continue.

The fraud occurred because two members of staff ‘who were related’ colluded. One processed cash receipts and prepared the weekly bank reconciliation; the other employee recorded customer receipts in the sales ledger. An unrelated sales ledger clerk was supposed to send out monthly customer statements but this was not performed. The bank reconciliations each had a small unreconciled amount but no-one reviewed the reconciliations after they were prepared. The fraud was only uncovered when the two employees went on holiday.

Control Mitigate Risk

Members of staff who are related should not be permitted towork in the same department whereby they can breachSegregation of duty controls.

This should reduce the risk of staff collusion and being ableto commit a fraud without easily being discovered.

Bank reconciliations should be reviewed by a responsibleofficial (different to the preparer of the reconciliation) on aregular basis. Any unreconciled amounts should be promptlyinvestigated and resolved.

A small unreconciled amount can actually represent twolarge balances which almost cancel each other out andhence could indicate significant problems with cash andbank.

Where fraud arises it can often be quickly spotted byperforming and reviewing a bank reconciliation.

Test of Control
