Slide 5- 1 Audit Evidence and Documentation
Slide 5- 2 The Third Standard of Field Work Sufficient appropriate evidential matter is to obtained by performing audit procedures to afford a reasonable basis for an opinion regarding the financial statements under audit.
Slide 5- 3 Management Assertions Embodied in the Financial Statements l Existence or Occurrence l Existence or Occurrence--Assets, liabilities, and owners equity accounts reflected in the financial statements exist; the recorded transactions have occurred. l Completeness l Completeness--All transactions, assets, liabilities, and elements of owners equity that should be presented in the financial statements are included. l Rights and Obligations l Rights and Obligations--The client has rights to assets and obligations to pay liabilities that are included in the financial statements. l Valuation or Allocation l Valuation or Allocation--Assets, liabilities, owners equity, revenues, and expenses are presented at amounts that are determined in accordance with generally accepted accounting principles. l Presentation and Disclosure--Accounts are described and classified in the financial statements in accordance with generally accepted accounting principles, and all material disclosures are provided. l Accuracy – Amounts and other data relating to recorded transactions have been recorded properly. l Cutoff – Transactions have been recorded in the proper accounting period.

Slide 5- 5 Audit Evidence Evidential matter: any information that corroborates or refutes an assertion
Slide 5- 6 Types of Evidence l Physical evidence l Third-party representations l Documentary evidence l Computations l Data Interrelationships l Client representations l Accounting records
Slide 5- 7 Types of Evidence Physical Evidence Evidence that can actually be seen by auditors. »This type of evidence is generally effective for supporting the existence assertion.
Slide 5- 8 Types of Evidence Third Party Representations l Confirmations l Lawyers Letters l Reports of Specialists
Slide 5- 9 Types of Evidence Documentary Evidence Four basic types (helps determine competence): l Created by outside parties and transmitted directly to auditor l Created by outside parties and held by client l Created and held by client l Electronic documents
Slide Types of Evidence Computations Computations are: l performed independently by auditor l used to verify mathematical accuracy of clients analyses and records
Slide Types of Evidence Data Interrelationships Data interrelationships (i.e., analytical procedures) rely on plausible relationships among financial and non- financial data. l Effective for testing reasonableness of certain account balances »Can be used as primary or corroborating evidence, depending on the nature of account
Slide Types of Evidence Oral and Written Client Representations l 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.
Slide Types 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
Slide Audit Procedures l Physical examination l Observation l Confirmation l Tracing l Vouching l Inspection l Reconciliation l Reperformance l Analytical procedures l Inquiry l Comparison Physical Evidence Third-Party Representations Documentary Evidence Computations Data Interrelationships Client Representations Accounting Records
Slide Competence of Evidential Matter l To be competent evidence must be: » Relevant – Must relate to the audit objective » Valid (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.

Slide Basic Approaches to Auditing Accounting Estimates l Review and test managements process for developing the estimate. l Independently develop an estimate to compare to managements estimate. l Review subsequent events or transactions bearing on the estimate.
Slide Functions of Working Papers l Provide support for the auditors opinion l Document the auditors compliance with generally accepted auditing standards, especially the standards of field work l Provide a means of assigning and coordinating audit work l Aid in supervising and reviewing the audit work l Aid in planning and conducting future audits
Slide Types of Working Papers l Audit Administrative Working Papers l Working Trial Balance l Lead Schedules (Grouping Sheets) l Adjusting and Reclassification Journal Entries l Supporting Schedules l Account Analysis l Reconciliations l Computational Working Papers l Corroborating Documents
Slide Types of Working Files l Current files »Typically arranged and indexed around accounts in clients financial statement »Support current years audit report l Permanent files »Document items of concern over multiple years »Provide summary of policies and organization of client »To preserve working papers that have little change over time.
Slide SARBOX Perspective l SARBOX requires the creation and maintenance, for a period of no less than seven years, of audit working papers sufficient to support the audit report. l Deliberate destruction of the audit documentation within the seven year period constitutes a criminal offense.
Slide More on Analytical Procedures l Required during planning and review stages of an audit l Analytical procedure process »Develop an expectation (amount or ratio) –Vertical analysis (common-size statements) –Horizontal (trend) analysis –Cross-sectional (industry) analysis »Determine acceptable difference »Compare actual results with expectation »Investigate significant differences
