ANALYTICAL

PROCEDURES

SECTION 7

What Are Analytical Procedures?• Evaluations of financial information made by a

study of plausible relationships among financial and non-financial data

• Where used?1. Planning

2. Substantive tests

3. Overall review

• Analytical involve comparisons of recorded amounts or ratios to expected amounts

• Expected amounts developed from a variety of sources

Source of Expected Amount Example

Financial information from prior periods

Anticipated results, such as budgets or forecasts

Relationships of elements of financial information within the period

Similar information regarding the industry in which the entity operates

Nature of Analytical Procedures• Three common types:

1. Trend analysis: The analysis of the change of an acount over time

2. Ratio analysis: A comparison of relationships among financial statement accounts

3. Reasonableness Tests: Computations usually involving non-financial data used to estimate an account balance

1. Trend Analysis

• Most common approach

• By analyzing changes in an account balance over past accounting periods

• The causal approach• Requires auditor to develop expected results

• The diagnostic approach• Compare the current amount to the trend to see if the current amount

appears to be acceptable

Diagnostic Approach Example

200X 200Y Change % Change Expected

1. Client bought new store on line in November

2. Increased sales due to new store

3. Client uses straight line. New store increased fixed asset base.

4. Increase % of sales commissions

5. OK

6. Paid off debt

7. Added store location

Simple Trend Analysis

• Involves determining an expected amount based on the account balance in prior periods

• E.g. A company may have an average annual increase in sales revenue of 10%

• What could be the cause if current years sales did not increase by 10%?

Regression Analysis

• Sales revenues can be affected by a variety of factors

• Can incorporate a number of variables

• Best fit technique

• From the graph

Y = 30,000 + 16.64X

• Job # 876 uses 962 DLH

• What would be the expected job cost?

• But if Job # 876 only cost $42,000

• Why?

2. Ratio Analysis

• Compares relationships among account balances

• Useful for both income and balance sheet

• Effective for income statement accounts because it typically compares the variations in operating activity

Time Series Analysis

• Ratios for an entity compared over time

Cross-Sectional Analysis

• Ratios compared at a given point in time

Methods of Ratio Analysis

• Financial ratios and common size statements

• Financial ratios• Analyzes relationships among account balances that the

auditor expects to:

• Remain stable over time

• Be common across firms

• Common-Size Statements

• In preparing common-size statement, the auditor converts the dollar amount of each account balance to a percentage of some relevant aggregate amount

• Time-series or cross-sectional

• Generally more useful for income statement accounts

• Use of Industry Ratios

• When performing cross-sectional analysis the auditor may use industry ratios

• Dun and Bradstreet

• 840 different classifications

• Limitations in Using Ratio Analysis

• Different accounting principles can make financial ratios non-comparable

• Ratios may differ among entities depending upon individual differences

• Auditor should exercise caution when comparing the client with the industry

3. Reasonableness Tests

• Computations that calculate an expected amount by using operating data

• What could one use if trying to estimate passenger revenue for a bus company or an airline?

• How about total room revenue for a hotel?

• One period model

• Reasonableness tests typically involve operating data which measures flow over time

• Can sometimes be excellent for the completeness assertion

• E.g. Expected revenues for an electrical utility

Timing of Analytical Procedures• Three phases of an audit:

1. Planning

2. Fieldwork; and

3. Final review

• The purpose of the analytical procedure depends on the audit phase

1. Planning

• Analytical procedures can draw attention to audit areas with significant potential for misstatement

• They can also enhance understanding of the client’s operations, transactions, and events

• The sophistication of the procedure can vary widely depending on the size and complexity of the client

• Determining risk

2. Fieldwork

• Used for substantive testing

• For a test of transactions an balances for inventory, what type of procedures can we use?

• How can an analytical procedures supply supporting or corroborating data for accounts receivable?

3. Final Review

• Analytical procedures are used in the overall or final review stage of the audit to assist the auditor in assessing

1. The adequacy of substantive tests.

2. The sufficiency of evidence

3. The validity of conclusions reached

• Should be performed by a person with in-depth knowledge

Reliability of Data Used to Develop Expectations

• More reliable if

1. From an independent source

2. Maintained by people not in a position to manipulate relevant accounting records

3. Derived from an adequate internal control structure

4. Subjected to audit testing in a prior year
