AUDIT EVIDENCE SECTION 5
Audit Evidence Relates to the third examination standard Sufficient appropriate audit evidence should be obtained by such means as: To afford a reasonable basis to support the? Audit procedure must be both effective and efficient
Who is responsible for the accuracy of the recorded transactions prepared in accordance with GAAP? Who is responsible for the detection of error and fraud? The fairness of presentation of the F/S? The auditors need to accumulate sufficient appropriate audit evidence
The Nature of Evidence The underlying accounting data is indispensable as it provides the basis for the client’s F/S UNDERLYING ACCOUNTING DATA Worksheets, Computations, Reconciliations CORROBORATING INFORMATION Confirmations, Computation, Analysis + SUFFICIENT APPROPRIATE AUDIT EVIDENCE =
Evidence Matter for Tests of Controls Tests of controls or compliance tests Second examination standard There should be a study and evaluation of those internal controls on which the auditor subsequently relies
Four primary concerns 1.Was the specific control procedure actually performed? 2.Was it performed properly? 3.By the appropriate person? 4.Throughout the period of reliance?
Two categories for tests of controls: 1.Document inspection 2.Inquiry and observation
Remember the third examination standard: The auditor must obtain sufficient and appropriate audit evidence to support the audit opinion The auditor employs substantive procedures to gather evidence relating to transactions and balances
Sufficiency of Evidence Pertains to quantity Auditor’s judgment may be affected by: Materiality and Risk Economic factors Size and characteristics of the population
Materiality and Risk Quantity inversely related to materiality Thus as materiality quantity Risk is directly related to quantity
Economic Factors Auditors work within economic limits Auditor should not accept client-imposed time and cost restrictions
Population Size and Characteristics Sampling is a practical necessity Generally the larger the population, the larger the sample There is an upper limit Population characteristics Uniform vs. non-uniform populations
Quality of Evidence How appropriate is the evidence? Considerations for quality 1.Relevance Evidence must be pertinent If the audit objective is inventory quantity? But how about ownership of a fixed asset?
2.Source The circumstances in which the evidence is obtained affects the quality of the evidence Testing the Accounts Receivable balance a.Examine evidence within the client’s organization b.Ask the customer to communicate with you directly Reviewing bank reconciliations a.Prepared by internal audit b.Prepared by the accounting manager
When evidence is obtained from independent sources A good system of internal control Direct personal knowledge of the auditor
3.Timeliness The date at which the evidence is obtained E.g.. Physical count at the balance sheet date 4.Objectivity Evidence from outside independent sources Contrast this to management making estimates on inventory obsolescence
Reasonable Basis Auditor is not required to have absolute certainty Reasonable basis pertains to the overall level of assurance Statistical quantification of assurance levels
Five factors that influence the auditor’s judgmental decision concerning reasonable basis 1.Professional Considerations CICA Handbook contains specific objectives to be obtained during the course of the examination Must justify departure Competition among firms (cost and fee conscious) Inadequate basis for an opinion (lawsuits?)
2.Integrity of Management Remember the responsibilities of management Doubt as to management integrity 3.Related Party Transactions Between parent and its subsidiaries Between a company and management “Arm’s length” bargaining not possible
4.Public vs. Privately Held Companies The general belief of auditors with regard to public companies 5.Financial Condition e.g. the threat of bankruptcy Remember the section on legal liability
Types of Evidence The third standard requires corroborating evidence of the following types: 1.Physical evidence 2.Confirmations 3.Documentary evidence 4.Written representations 5.Mathematical evidence 6.Visual evidence 7.Oral evidence 8.Analytical evidence
1.Physical Evidence Used widely for tangible assets Direct personal knowledge 2.Confirmations Direct written response by knowledgeable third parties to specific requests Useful in verifying existence and accuracy
3.Documentary Evidence Cheques, invoices, contracts, minutes How reliable is the document? Externally generated third party Internally created Documents are used extensively to establish Terms Occurrence Propriety of exchange transactions Ownership of assets Claims of creditors Accuracy and completeness of accounting records Internal control
4.Written Representations A signed statement by a responsible and knowledgeable individual Management representation letter Also written representations from outside experts
5.Mathematical Evidence Auditors computations E.g. checking journal footings 6.Visual Evidence Auditor witnesses the performance of an assigned responsibility or observes the security of inventory
Substantive Tests Evidential matter required by the third examination standard is obtained through two general classes of auditing procedures 1.Test of details of transactions and balances 2.Analytical procedures
Tests of Transactions and Balances 1.Tracing a sales invoice to the accounting records 2.Counting cash on hand What are both tests doing?
Analytical Procedures Designed to verify the reasonableness of relationships among various data to identify unusual fluctuations in such data E.g. the magnitude of the percentage increase/decrease of accounts receivable from the prior year to the current year What other measures can be used?
Auditing Procedures for Tests of T/A’s and Balances What does GAAS require? Most widely used: Inspect Observe Confirm Inquire Trace Vouch Recalculate Count Scan
1.Inspection Careful scrutiny or detailed examination Document inspection provides for evaluating documentary evidence Inspection of a tangible asset provides a means for evaluation of ?
2.Observation Watch and witness the performance of an activity Direct personal knowledge 3.Confirmation Formal inquiry that enables the auditor to obtain information directly from an independent source
4.Inquiry Oral or written inquiry by the auditor 5.Tracing The auditor begins with the document(s) created when the transaction is first executed and proceeds to follow the evidence through the recording process Effectives of this procedure is enhanced by?
6.Vouching The auditor works from the accounting records back to the documentation that served as a basis for entry The opposite of tracing 7.Recalculation Reperformance of calculations
8.Counting Physical count of tangible resources Any other type of counting? 9.Scanning The rapid review of documents, records, and schedules
Evaluation of Evidential Matter The auditor should be objective, careful, and thorough Limit the use of evidence to the specific assertion No single piece of evidence is absolutely conclusive
Nature and Purpose of Working Papers Working papers provide : The principal support for? Evidence that the examination was in accordance with? A means for co-ordination and supervision
Types of Working Papers Usually classified into the following groups: 1. Audit plans and audit programs. 2. Working trial balance. 3. Schedules and analyses. 4. Audit memoranda. 5. Adjusting and reclassifying entries.
The General Standard Working papers provide evidence of the auditor’s technical training and proficiency Show ability to apply auditing procedures applicable in the circumstances The content of the working papers reveals the scope of the work
The Examination Standards Used for co-ordination and control The auditor’s study and evaluation of internal control should be clearly documented Working papers provide a means for documentation of evidence on which to base an opinion
The Reporting Standards Facilitate the preparation of the auditor’s report Working papers should be traceable to the financial statements Evidence to show financial statements conform to GAAP

Problem 2: The following audit procedures were performed in the audit of inventory to satisfy specific balance-related audit objectives as discussed in Chapter 5. The audit procedures assume the auditor has obtained the inventory count records that list the client’s inventory. The general balance-related audit objectives from Chapter 5 are also included. AUDIT PROCEDURES 1. Using audit software, extend unit prices time quantity, foot the extensions, and compare the total to the general ledger. 2. Trace selected quantities from the inventory listing to the physical inventory to make sure the items exist and the quantities are the same. 3. Question operating personnel about the possibility of obsolete or slow-moving inventory. 4. Select a sample of quantities of inventory in the factory warehouse, and trace each item to the inventory count sheets to determine if it has been included and if the quantity and description are correct. 5. Using both this year’s and last year’s inventory data files, compare quantities on hand and unit prices, printing any with greater than a thirty percent or $15,000 variation from one year to the next. 6. Examine sales invoice and contracts with customers to determine if any goods are out on consignment with customers. Similarly, examine vendors’ invoices and contracts with vendors to determine if any goods on the inventory listing are owned by others. 7. Send letters directly to third parties who hold the client’s inventory and request that they respond directly to us.
