Preface
Written on the threshold of the twenty-first century - a time that is increasingly marked by globalization of products and services, rapid progress in financial analytics, and technological breakthroughs - this text addresses itself to managers and professionals. Typically, its readers have, or are about to have, fiduciary responsibilities and/or an immediate and deep interest in assuring the evolution of internal control for reasons of good governance.
The International Organization for Securities Commissions (IOSCO) says that a control structure can only be as effective as the people who operate it. Therefore, strong commitment by the board as well as by all managers and professionals working for a financial institution, a manufacturing enterprise, or any other organization, is a prerequisite to the good functioning of internal control - that is, the intelligence necessary to ascertain that an entity functions effectively, according to ethical standards, board policies, and regulatory rules.
One of the lessons managers should learn very early in their careers is that they have to deal with the world as they find it, not as they might wish it to be. From this derives the need for interpretation of information internal control provides, looking for presence or absence of compliance and asking why and how there are deviations, and what that means for their company's present and future. Here are, in a nutshell, the five basic principles of an effective internal control.
• Internal control is a dynamic system covering all types of risk, addressing fraud, assuring transparency, and making possible reliable financial reporting.
• The chairman of the board, the directors, the chief executive officer (CEO), and senior management are responsible and accountable for internal control.
• Beyond risks, internal control goals are preservation of assets, account reconciliation, and compliance. Laws and regulations impact on internal control.
• The able management of internal control requires policies, organization, technology, open communications, access to all transactions, real-time operation, quality control, and corrective action.
• Internal control must be regularly audited by internal and external auditors to ensure its rank and condition, and to see to it there is no cognitive dissonance at any level.

Preface xvn
Cognitive dissonance is the name for the organizational phenomenon whereby people ignore something that does not fit their view of the world and pretend it does not exist. This is distinct from outright fraud, or the intentional falsification of events and records. But, like fraud, cognitive dissonance is anathema to the proper functioning of an internal control system, and therefore internal auditors and external auditors must be on the alert.
An organizational issue to attract the auditor's attention in examining the lines of authority and accountability for internal control purposes is the separation of responsibility for the measurement, monitoring, and supervision of exposure from that of day-to-day operations. Auditors are, or at least should be, well aware that the execution of any transaction and the inventorying of any position are giving rise to risk. Risk has to be monitored and managed, but this must independent of trading, lending, and other revenue sidelines.
Auditing is part of senior management duties. The role of internal audit is to analyze and reconcile accounts, test the dependability of financial statements, evaluate qualitative business aspects, detect fraud, and master internal control details. The internal auditing function must be staffed with first-class people, be supported by the best technology, and report directly to the board or the Audit Committee. In executing their functions, auditors should form a view on the correctness and efficiency of the way in which the company is managed.
* * *
With globalization, deregulation, and the advent of derivatives, credit institutions, as well as the treasury operations of manufacturing, merchandising, and service companies, are finding that their traditional tools for management control no longer suffice. They must develop more efficient processes able to measure and monitor their risks in real-time. They must also have tools that permit to exercise timely and accurate control.
This is well known to national and international regulators who have issued a number of directives to enhance existing means for compliance, and promote risk management systems - including the use of Audit Committees and the redefining of internal control functions. Regulatory authorities are also seeing to it that both the members of the board of directors and external auditors are responsible for the company's system of internal checks and balances, and for the implementation of rigorous solutions able to provide assurance against material misstatement or loss.
XV111 Preface
The book the reader has on hand addresses the need for a direct confirmation that senior management and the auditors have reviewed the effectiveness of the system of internal financial and operational controls. This text is divided into three parts. Part 1 defines both auditing and internal control, then explains why internal control must be audited and in which way this should be done to improve upon the quality of deliverables.
Chapter 1 addresses the role of auditing in an organization. It demonstrates that auditing is an indispensable instrument of management, and documents that rigorous auditing can provide value-added services. This chapter also outlines the functions and responsibilities of the Auditing Committee, at the level of the board of directors. Its existence has been strongly recommended by the Basle Committee on Banking Supervision of the Bank for International Settlements (BIS).
Chapter 2 focuses on internal control. After defining the internal control functions and the senior management policies on which these should rest, it presents to the reader the successive steps necessary for implementing a rigorous internal control system, demonstrating why properly studied and applied internal controls can be instrumental in curbing not only fraud but as well credit risk, market risk, operational risk, and other major exposures.
Chapter 3 examines the need for internal controls from the viewpoint of globalization of financial markets. It brings home the point that important differences in accounting systems handicap internal control and auditing, and it documents how conflicts of interest work to the detriment of internal control - and therefore of the company's ability to take hold of itself.
The theme of Chapter 4 is new standards for auditing internal controls and risk management systems. Practical examples range from the more classical auditing of cash flow to risk-based auditing. A methodology for auditing the internal control system is presented in Chapter 5. Internal control information is compared to military intelligence, and applications examples are taken from trading in derivative financial instruments.
Accurate information passed in a timely fashion to decision-makers can enable them to take appropriate steps whether these focus on new business opportunities or on control action. The latter is the role of internal control intelligence. However, numbers and statistics are only a small part of the game. Much of the risk taken by a company because of trading and inventoried positions is inherently unqualified. Yet, we try not only to qualify it but also, whenever possible, to quantify it - because this is the only way to control it.
On these premises rests Part II, which addresses top management's accountability for internal control. The line of responsibilities starts at the
Preface xix
chairman of the board, and though authority is delegated responsibility is not; it always stays at the top. This is precisely Chapter 6's subject. The text explains why effective internal control requires trustworthy people all the way down the line of command. It also brings into perspective the need for restructuring, and makes the point that it is wise to keep away from creative accounting practices.
The synergy between internal controls and core functions is the next important theme examined. Chapter 7 looks into core functions from the perspective of a credit institution. Emphasis is placed on both a priori and a posteriori studies as well as on compliance. Attention is also paid to management intent and on why transparency is practically synonymous with market discipline.
Transparency requires both appropriate board policies and an efficient internal control structure. This is explained in Chapter 8, which takes as an example of necessary policies those of a better-known brokerage in the United States. The reader is also presented with advice on useful tests on the way internal controls works, tips on improvements, and a discussion on the role of advanced technology in making the internal control system so much more efficient.
Technology can be instrumental in distilling data streams and in mining databased events, but as Part III explains through case studies for information to become intelligence there is no substitute for sound and well informed analysis. On the bottom line, internal control intelligence is the interpretation of facts and figures and educated guesswork on management intent at all levels of the organization.
The practical examples in Chapter 9 revolve around applying internal control to our institution's limits system, and to other prudential benchmarks put in place by top management. The text presents the reasons why setting limits is a business requiring know-how and imagination, as well as a feedback which makes possible dynamic limits management. The latter is the theme of Chapter 10, which elaborates further on the role of auditing in controlling the calculation of prices and risk premiums, estimating the amount of leveraging, and identifying a range of risks from equity trading to currency positions.
Chapter 11 changes the frame of reference by examining the role of internal control in engineering and manufacturing. Starting with long-termism and short-termism in research and development (R&D), it proceeds with internal control applied to engineering design. Practical examples are taken from project management and design reviews, as well as from prototyping and quality assurance. Unavoidably, this leads to a discussion on information technology.
XX Preface
Effective internal control and high technology are inseparable, particularly so in a very dynamic, globalized market. Chapter 12, therefore, focuses its attention on the services information technology provides in connection to the auditing of internal controls. It also explains why the use of advanced technology is not a fad but an obligation. The cutting edge of technology is never a bleeding edge unless we don't know what we are doing. But falling behind in technology has often proved to be the bleeding side of an internal control system.
While much can be done by way of supporting an internal control structure through human resources employed by our firm, external auditors can also play a major role. This is the theme of Chapter 13, which addresses both classical and modern duties of external auditors, in connection with scrutiny and verification of our company's internal controls. Part of this discussion is outsourcing, its strengths and weaknesses; another part is the responsibilities of all players involved in auditing internal controls.
The careful reader who considers all of the points which have been made will appreciate that internal control should be examined from different angles to assure the appropriateness of policies and procedures. Among the issues to which attention should be paid is auditing staff qualifications. Is the staff experienced in analyzing an internal control system and its effectiveness? Is a training programme in effect? Are members of the staff experienced in specialized areas such as risk management and information technology?
Other questions, too, are key to the interpretation of intelligence. Does the depth coverage of the audits appear to be sufficient? Is the chief auditor member of an executive system planning committee? Is he or she reporting directly to the chairman or the auditing committee? Behind these queries are the reasons why from Chapter 1 auditing procedures have been brought under a magnifying glass. Do these procedures employ statistically valid sampling techniques, with acceptable reliability and precision? Is the content of auditing independent of adverse influences by different interests? Has the auditing of internal control been formally established by the board of directors?
It worth practically nothing to audit internal controls if the intelligence being collected is distorted by self-imposed limitations and deliberate misconceptions. Distortions of factual and documented discoveries in the auditing of internal control is a very dangerous business for any company, no matter how senior and how clever its board, CEO, and top management may be. This has been the conclusion of the research which led to this book.
