5Audit Evidence Evidential matter: any information that corroborates or refutes an assertion
7Types of Evidence Physical Evidence Evidence that can actually be seen by auditors.This type of evidence is generally effective for supporting the existence assertion.
8Types of Evidence Third Party Representations ConfirmationsLawyers’ LettersReports of Specialists
9Types of Evidence Documentary Evidence Four basic types (helps determine competence):Created by outside parties and transmitted directly to auditorCreated by outside parties and held by clientCreated and held by clientElectronic documents
10Types of Evidence Computations Computations are:performed independently by auditorused to verify mathematical accuracy of client’s analyses and records
11Types of Evidence Data Interrelationships Data interrelationships (i.e., analytical procedures) rely on plausible relationships among financial and non-financial data.Effective for testing “reasonableness” of certain account balancesCan be used as primary or corroborating evidence, depending on the nature of account
12Types of Evidence Oral and Written Client Representations Responses to questions and inquiries to clients during an audit constitute audit evidence.Oral representations are generally not sufficient as primary evidence, but may provide corroboration for other evidence.Written representations (representation letter) are required, but should not be used as a substitute for other audit procedures.
13Types of Evidence Accounting Records Clients’ accounting records (e.g. ledgers and journals) may provide worthwhile evidence in themselves.Depends on the effectiveness of internal controls
15Competence of Evidential Matter To be competent evidence must be:RelevantMust relate to the audit objectiveValid (Reliable)Independent sources have greater reliability than those within the client organization.Strong internal control increases reliability of evidence created within the client organization.Directly obtained evidence is more reliable than evidence obtained second hand.77

17Basic Approaches to Auditing Accounting Estimates Review and test management’s process for developing the estimate.Independently develop an estimate to compare to management’s estimate.Review subsequent events or transactions bearing on the estimate.1010

20Types of Working Files Current files Permanent files Typically arranged and indexed around accounts in clients’ financial statementSupport current year’s audit reportPermanent filesDocument items of concern over multiple yearsProvide summary of policies and organization of clientTo preserve working papers that have little change over time.44
23SARBOX PerspectiveSARBOX requires the creation and maintenance, for a period of no less than seven years, of audit working papers sufficient to support the audit report.Deliberate destruction of the audit documentation within the seven year period constitutes a criminal offense.
