Determining the Extent of TODB • Risk model factors • Acceptable audit risk • Inherent risk • Control risk • Materiality(partially depends on AAR)
Determining the Extent of TODB • Risk model factors • Materiality • Results of other tests • Tests of controls • Substantive tests of transactions • Analytical procedures
Analytical Procedures • 2007 Gross 2006 Gross • Margin Margin • GW IND GW IND • Hardwood 36.3 32.4 36.4 32.5 • Softwood23.9 22.0 20.3 22.1 • Plywood 40.3 50.1 44.2 54.3
Analytical Procedures • Softwood increased 3.9%, industry stable • Changes usually most informative(also want to understand differences from industry) • Easier to spot errors in disaggregated data
Analytical Procedure Follow-up • Client will be able to suggest likely non-error causes, which you will evaluate. • Consider error causes • What errors would cause gross profit to increase?
Error Causes of Gross Profit Increase • Sales overstated • Fictitious sales • Cutoff error - January sale recorded in December (COS not matched) • Cost of sales understated • Inventory overstated • Purchases understated or cutoff error - December purchase recorded in January
Extent of Tests • Amount of testing for TODB objectives will depend upon results of TOT for related transaction objectives: • see following slide for related objectives (from Ch. 6) • see table in notes for specific tests • main sampling application in TODB for AR is confirmations

Confirmations • Key Objectives • existence • accuracy (valuation) • Weak evidence for completeness - why?
Confirmation are required unless (SAS # 67): • Accounts receivable are immaterial. • Confirmations are expected to be ineffective. • Combined IR and CR are low, and other evidence reduces audit risk to an acceptably low level.
Confirmations • Why would auditors like to minimize confirmations? • What is the alternative to confirmations?
Positive Confirmations • Emphasis in testing is usually larger, and older accounts • Testing may be balance or individual invoice • Invoice may increase response rate • Reduces extent of reconciling items • However, provides less assurance
Negative Confirmations • Used when • Internal control effective • Many small balances • Customers expected to give adequate consideration
Alternative Procedures • 1. Subsequent cash receipts • 2. Shipping document • Any untested portion should be treated as an error for projection purposes.
95% of returned confirmations indicated the customer owed a smaller balance. This may be explained by: • a. Cash receipts journal was held open after • year-end. • b. There are a large number of unrecorded • liabilities. • c. Sales journal was closed prior to y/e. • d. Sales journal was held open after year- • end.

Auditing Allowance • Beginning Balance from prior year • Less: write-offs tested • Plus: current provision • (bad debt expense) residual • Ending balance tested TODB
Cutoff Testing • Sales Cutoff - Primary focus is on sales recorded just beforeyear-end • Cash receipts cutoff -Primary focus is on receipts recorded beforeyear-end • Purchases Cutoff -Primary focus is on purchases recorded afteryear-end • ( does not affect A/R)
Sales Cutoff Errors • Key issue is whether COS is matched. Determining factor is whether good are included or excluded from inventory. • Y/E physical - inventory normally correct
Sales Cutoff Errors • Shipped 1/2 Sale - $10,000 • Recorded 12/31 COS - $7,000 • Counted in Income Effect • inventory? of Error___ • Yes $10,000 • No $3,000
Cutoff Adjustments • Error 1 - inventory correct • Sales 10,000 • Accounts receivable 10,000 • Error 2 - inventory not correct • Sales 10,000 • Inventory 7,000 • Accounts receivable 10,000 • Cost of sales 7,000
