internal control
Internal Control
  • Internal Control is a state that management strives to achieve to provide reasonable assurance that the firm’s objectives will be achieved
  • These controls encompass all the measures and practices that are used to counteract exposures to risks
  • The control framework is called the Internal Control Structure
objectives of the internal control structure
Objectives of the Internal Control Structure
  • Promoting Effectiveness and Efficiency of Operations
  • Reliability of Financial Reporting
  • Safeguarding assets
  • Checking the accuracy and reliability of accounting data
  • Compliance with applicable laws and regulations
  • Encouraging adherence to prescribed managerial policies

control environment
Control Environment
  • The Control Environment establishes the tone of a company, influencing the control consciousness of its employees
  • It is comprised of seven components:
    • Management philosophy and operating style
    • Integrity and ethical values
    • Commitment to competence
    • The Board of Directors and the Audit Committee
    • Organizational Structure
    • Assignment of authority and responsibility
    • Human resources policies and practices
    • External Influences
highlights of ce components i
Highlights of CE Components - I
  • Management Philosophy and Operating Style
    • Does management emphasize short-term profits and operating goals over long-term goals?
    • Is management dominated by one or a few individuals?
    • What type of business risks does management take and how are these risks managed?
    • Is management conservative or aggressive toward selecting from available alternative accounting principles?

Figure 7-2

highlights of ce components ii
Highlights of CE Components - II
  • Organization Structure
    • Is an up-to-date organization chart prepared, showing the names of key personnel?
    • Is the information systems functionseparated from incompatible functions?
    • How is the accounting departmentorganized?
    • Is the internal audit function separate and distinct from accounting?
    • Do subordinate managers report to more than one supervisor?

Figure 7-2 Continued

highlights of ce components iii
Highlights of CE Components - III
  • Assignment of Authority and Responsibility
    • Does the company prepare written employee job descriptions defining specific duties and reporting relationships?
    • Is written approval required for changes made to information systems?
    • Does the company clearly delineate employees and managers the boundaries of authority-responsibility relationships?
    • Does the company properly delegate authority to employees and departments?

Figure 7-2 Continued

highlights of ce components iv
Highlights of CE Components - IV
  • Human Resource Policies and Practices
    • Are new personnel indoctrinated with respect to Internal Controls, Ethics Policies, and Corporate Code of Conduct?
    • Is the company in compliance with the ADA? The EEOA?
    • Are Grievance Procedures to manage conflict in force?
    • Does the company maintain a sound Employee Relations program?
    • Do employees work in a safe, healthy environment?
    • Are Counseling Programs available to employees?
    • Are proper Separation Programs in force for employees who leave the firm?

Figure 7-2 Continued

key functions performed by audit committees
Key Functions Performed by Audit Committees
  • Establish an Internal Audit Department
  • Review the Scope and Status of Audits
  • Review Audit Findings with the Board and ensure that Management has taken proper action recommended in the Audit Report and Letter of Reportable Conditions
  • Maintain a direct Line of Communication among the Board, Management, External and Internal Auditors, and periodically arrange Meetings among the parties

Figure 7-3

key functions performed by audit committees11
Key Functions Performed by Audit Committees
  • Review the Audited Financial Statements with the Internal Auditors and the Board of Directors
  • Require periodic Quality Reviews of the operations of the Internal Audit Departments to identify areas needing improvement
  • Supervise special investigations, such as Fraud Investigations
  • Assess the performance of Financial Management
  • Require the Review of Compliance with Laws and Regulations and with Corporate Codes of Conduct

Figure 7-3

risk assessment
Risk Assessment
  • Top management must be directly involved in Business Risk Assessment.
  • This involves the Identification and Analysis of Relevant Risks that may prevent the attainment of Company-wide Objectives and Objectives of Organizational Units and the formation of a plan to determine how to manage the risks.
control activities i
Control Activities - I
  • Control Activities as related to Financial Reporting may be classified according to their intended uses in a system:
    • Preventive Controls block adverse events, such as errors or losses, from occurring
    • Detective Controls discover the occurrence of adverse events such as operational inefficiency
    • Corrective controls are designed to remedy problems discovered through detective controls
    • Security Measuresare intended to provide adequate safeguards over access to and use of assets and data records
control activities ii
Control Activities - II
  • Control Activities relating to Information Processing may also be classified according to where they will be applied within the system
    • General controls are those controls that pertain to all activities involving a firm’s AIS and assets
    • Application controls relate to specific accounting tasks or transactions
  • The overall trend seems to be going from specific application controls to more global general controls
control activities iii
Control Activities - III
  • Performance Reviews
    • Comparing Budgets to Actual Values
    • Relating Different Sets of Data-Operating or Financial-to one another, together with Analyses of the relationships and Investigative and Corrective Actions
    • Reviewing Functional Performance such as a bank’s consumer loan manager’s review of reports by branch, region, and loan type for loan approvals and collections
information communication
Information & Communication
  • All Transactions entered for processing are Valid and Authorized
  • All valid transactions are captured and entered for processing on a Timely Basis and in Sufficient Detail to permit the proper Classification of Transactions
  • The input data of all entered transactions are Accurate and Complete, with the transactions being expressed in proper Monetary terms
  • All entered transactions are processed properly to update all affected records of Master Files and/or Other Types of Data sets
  • All required Outputs are prepared according to Appropriate Rules to provide Accurate and Reliable Information
  • All transactions are recorded in the proper Accounting Period

Risk
  • Business firms facerisksthat reduce the chances of achieving their control objectives.
  • Risk exposures arise from internal sources, such as employees, as well as external sources, such as computer hackers.
  • Risk assessment consists of identifying relevant risks, analyzing the extent of exposure to those risks, and managing risks by proposing effective control procedures.
some typical sources of risk i
Some Typical Sources of Risk - I
  • Clerical and Operational Employees, who process transactional data and have access to Assets
  • Computer Programmers, who have knowledge relating to the Instructionsby which transactions are processed
  • Managers and Accountants, who have access to Records and Financial Reports and often have Authority to Approve Transactions

Figure 7-4

some typical sources of risk ii
Some Typical Sources of Risk - II
  • Former Employees, who may still understand the Control Structure and may harbor grudges against the firm
  • Customers and Suppliers, who generate many of the transactions processed by the firm
  • Competitors, who may desire to acquire confidential information of the firm
  • Outside Persons, such as Computer Hackers and Criminals, who have various reasons to access the firm’s data or its assets or to commit destructive acts
  • Acts of Nature or Accidents, such as floods, fires, and equipment breakdowns

Figure 7-4 Continued

types of risks
Types of Risks
  • Unintentional errors
  • Deliberate Errors (Fraud)
  • Unintentional Losses of Assets
  • Thefts of assets
  • Breaches of Security
  • Acts of Violence and Natural Disasters
factors that increase risk exposure
Factors that Increase Risk Exposure
  • Frequency - the more frequent an occurrence of a transaction thegreater the exposure to risk
  • Vulnerability - liquid and/or portable assets contribute to risk exposure
  • Size of the potential loss- the higher the monetary value of a loss, the greater the risk exposure
problem conditions affecting risk exposures
Problem Conditions Affecting Risk Exposures
  • Collusion (both internal and external), which is the cooperation of two or more people for a fraudulent purpose, is difficult to counteract even with sound control procedures
  • Lack of Enforcement Management may not prosecute wrongdoers because of the potential embarrassment
  • Computercrime poses very high degreesof risk, and fraudulent activities are difficultto detect
computer crime
Computer Crime
  • Computer crime (computer abuse)is the use of a computer to deceive for personal gain.
  • Due to the proliferation of networks and personal computers, computer crime is expected to significantly increase both in frequency and amount of loss.
  • It is speculated that a relatively small proportion of computer crime gets detected and an even smaller proportion gets reported.
examples of computer crime
Examples of Computer Crime
  • Theft of Computer Hardware & Software
  • Unauthorized Use of Computer Facilities for Personal Use
  • Fraudulent Modification or Use of Data or Programs
reasons why computers cause control problems
Reasons Why Computers Cause Control Problems
  • Processing is Concentrated
  • Audit Trails may be Undermined
  • Human Judgment is bypassed
  • Data are stored in Device-Oriented rather than Human-Oriented forms
    • Invisible Data
    • Stored data are Erasable
    • Data are stored in a Compressed form
    • Stored data are relatively accessible
  • Computer Equipment is Powerful but Complex and Vulnerable
feasibility of controls
Feasibility of Controls
  • Audit Considerations
  • Cost-Benefit Considerations
    • Determine Specific Computer Resources Subject to Control
    • Determine all Potential Threats to the company’s Computer System
    • Assess the Relevant Risks to which the firm is exposed
    • Measure the Extent of each Relevant Risk exposure in dollar terms
    • Multiply the Estimated Effect of each Relevant Risk Exposure by the Estimated Frequency of Occurrence over a Reasonable Period, such as a year
    • Compute the Cost of Installing and Maintaining a Control that is to Counter each Relevant Risk Exposure
    • Compare the Benefits against the Costs of Each Control
legislation
Legislation
  • The Foreign Corrupt Practices Act of 1977
  • Of the Federal Legislation governing the use of computers, The Computer Fraud and Abuse Act of 1984 (amended in 1986)is perhaps the most important
    • This act makes it a federal crime to intentionally access a computer for such purposes as: (1) obtaining top-secret military information, personal, financial or credit information
    • (2) committing a fraud
    • (3) altering or destroying federal information
methods for thwarting computer abuse
Methods for Thwarting Computer Abuse
  • Enlist top-management support so that awareness of computer abuse will filter down through management ranks.
  • Implement and enforce control procedures.
  • Increase employee awareness in the seriousness of computer abuse, the amount of costs, and the disruption it creates.
  • Establish a code of conduct.
  • Be aware of the common characteristics of most computer abusers.
methods for thwarting computer abuse29
Methods for Thwarting Computer Abuse
  • Recognize the symptoms of computer abuse such as:
    • behavioral or lifestyle changes in an employee
    • accounting irregularities such as forged, altered or destroyed input documents or suspicious accounting adjustments
    • absent or ignored control procedures
    • the presence of many odd or unusual anomalies that go unchallenged
  • Encourage ethical behavior
