Amol Gore (1) and Guruprasad Murthy (2) VN BRIMS Institute of Research and Management Studies, India Abstract This case documents the evolution of ‘fraud culture’ at Enron Corporation and vividly explicates the downfall of this giant organization that has become a synonym for corporate deceit. The objectives of this case are to illustrate the impact of culture on established, rational management control procedures and emphasize the importance of resolute moral leadership as a crucial qualification for board membership in corporations that shape the society and affect the lives of millions of people. The data collection for this case has included various sources such as key electronic databases as well as secondary data available in the public domain. The case is prepared as an academic or teaching purpose case study that can be utilized to demonstrate the manner in which corruption creeps into an ambitious organization and paralyses the proven management control systems. Since the topic of corporate practices and fraud management is inherently interdisciplinary, the case would benefit candidates of many courses including Operations Management, Strategic Management, Accounting, Business Ethics and Corporate Law.
  • Official Versions Vs Facts

    Official Versions Vs Facts

    1 This text below is inspired by a translation from a French text that was published on the website of Paul Jorion in late June 2017, ie about only 2 weeks after this website would go live. I answered here a very straight question: “how do you differ from the official version?” And here is my “story”, the only one that have conveyed since 2012. It was then meant to summarize how my website differs from all the reports that the bank and the authorities have made on the “London Whale” case. It was 143 pages long for Paul Jorion. Now it is 29 pages long. What I have added are further details on key topics like ‘profits’, like ‘orders’, like ‘valuation’, like ‘mismarking’…. Needless to say, this account vastly differs from any media reporting although some outlets are closer than others. This text below thus predated by a month or so the decisions of the DOJ as disclosed on July 21st 2017. It may well have been the “recent statements and writings” that would shake the tree. It contradicted ahead of times the WSJ subsequent article of August 3rd 2017. Yet it corroborated the statements of Dimon on August 8th 2017 to some extent and clarified ahead of times the context of the ultimate decision of the SEC in late August 2017. But, back in June 2017, this text was also displaying my ‘story’ as an anchor amid all the changing stories that would have been conveyed since 2012 and onwards… In sharp contrast to what all the authorities and the bank would do between 2012 and 2018, I will deploy only one “story” to tell all along, be that on the public stage or confidentially towards the authorities.

    Charting a Course to Autonomy: Bureaucratic Politics and the Transformation of Wall Street by Peter Joseph Ryan A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Political Science in the GRADUATE DIVISION of the UNIVERSITY OF CALIFORNIA, BERKELEY Committee in charge: Professor Paul Pierson, Chair Professor J. Nicholas Ziegler Professor Neil Fligstein Spring 2013 Charting a Course to Autonomy: Bureaucratic Politics and the Transformation of Wall Street Copyright c 2013 by Peter Joseph Ryan Abstract Charting a Course to Autonomy: Bureaucratic Politics and the Transformation of Wall Street by Peter Joseph Ryan Doctor of Philosophy in Political Science University of California, Berkeley Professor Paul Pierson, Chair Over the past three decades, federal regulators have been at the heart of transformations that have reshaped the financial services industry in the United States and by definition, global markets. It was, for example, the Federal Reserve that initiated and developed risk- based capital standards, rules that are now at the heart of prudential regulation of financial firms across the globe. Federal regulators played a central role in preventing regulation of the emerging ‘over-the-counter’ derivatives market in the late 1980s and early 1990s, actions that later had dramatic consequences during the 2007-2008 financial crisis. The Securities and Exchange Commission took critical decisions regarding the prudential supervision of investment banks, decisions that greatly contributed to the end of the independent invest- ment banking industry in the United States in 2008. Finally regulators played an important role in setting the agenda and shaping the outcomes of the Dodd-Frank Wall Street Reform Act of 2010, the most sweeping and comprehensive piece of legislation affecting the industry since the New Deal.

(USA) Online ISSN: 2249-4588 & Print ISSN: 0975-5853 The Financial Collapse of the Enron Corporation and Its Impact in the United States Capital Market By Prof. Edel Lemus, M.I.B.A Carlos Albizu University, U nited States Abstract- The purpose of this article is to review the collapse of the Enron Corporation and the collapse’s effect on the United States financial market. Enron Corporation, the seventh largest company in the United States, misguided its shareholders by reporting $74 billion profit of which $43 billion was detected as fraud. Moreover, according to the association of fraud examiners $2.9 trillion was lost because of employee fraud. For example, as presented by Kieso, Weygandt, and Warfield (2013), in a global survey study that was conducted in 2013, it was reported that 3,000 executives from 54 countries were involved in fraudulent financial reporting. Therefore, the world of accounting is dominated by the top four accounting firms known as (1). PricewaterhouseCoopers (PwC), (2). Deloitte & Touche (DT), (3). Ernst & Young (EY) and (4). KPMG which represent a combined income of $80 billion.

  • Lifting the Veil of Sarbanes-Oxley

    Lifting the Veil of Sarbanes-Oxley

    LIFTING THE VEIL OF SARBANES -OXLEY REVELATIONS THROUGH DECEMBER 1, 2002 By ∗ Byron F. Egan, Dallas, TX Sabrina A. McTopy, Houston, TX On July 30, 2002 President Bush signed the Sarbanes -Oxley Act of 2002 (H.R. 3763) (the “SOB ”) intended to protect investors by improving the accuracy and reliability of corporate disclosures made pursuant to the securities laws. This is the “tough new corporate fraud SOB” being trumpeted by the politicians and in the media. Among other things, the SOB amends the Securities Exchange Act of 1934 (the “ 1934 Act ”) and the Securities Act of 1933 (the “ 1933 Act ”). Although the SOB does have some specific provisions, and generally establishes some important public policy changes, it will be implemented in large part through rules t o be adopted by the Securities and Exchange Commission ( “SEC” ) in various designated periods of time after July 30, 2002 – generally, 30 days (August 29, 2002), 180 days (January 26, 2003) and 270 days (April 26, 2003). As is always the case with broad gr ants of authority to a regulatory body, the rules may well contain some surprises. Further, the SEC will have opportunity through rulemaking under the SOB, as well as action on corporate governance proposals of the stock exchanges, to delve much farther i nto corporate governance than it has in the past. SUMMARY To What Companies Does SOB Apply . The SOB is generally applicable to all companies required to file reports with the SEC under the 1934 Act (“ reporting companies ”) or that have a registration state ment on file with the SEC under the 1933 Act, in each case regardless of size (collectively “ public companies ”).
  • Enron Scandal: the Fall of a Wall Street Darling

    Enron Scandal: the Fall of a Wall Street Darling

    Enron Scandal: The Fall of a Wall Street Darling The story of Enron Corp. is the story of a company that reached dramatic heights, only to face a dizzying fall. Its collapse affected thousands of employees and shook Wall Street to its core. At Enron's peak, its shares were worth $90.75; when it declared bankruptcy on December 2, 2001, they were trading at $0.26. To this day, many wonder how such a powerful business, at the time one of the largest companies in the U.S, disintegrated almost overnight and how it managed to fool the regulators with fake holdings and off-the-books accounting for so long. Enron's Energy Origins Enron was formed in 1985, following a merger between Houston Natural Gas Co. and Omaha-based InterNorth Inc. Following the merger, Kenneth Lay, who had been the chief executive officer (CEO) of Houston Natural Gas, became Enron's CEO and chairman and quickly rebranded Enron into an energy trader and supplier. Deregulation of the energy markets allowed companies to place bets on future prices, and Enron was poised to take advantage. In 1990, Lay created the Enron Finance Corp. To head it, he appointed Jeffrey Skilling, whose work as a McKinsey & Co consultant had impressed Lay. Skilling was at the time one of the youngest partners at McKinsey. Why Enron Collapsed Skilling joined Enron at an auspicious time. The era's regulatory environment allowed Enron to flourish. At the end of the 1990s, the dot-com bubble was in full swing, and the Nasdaq hit 5,000.

    The Enron Corpus: Where the Email Bodies Are Buried?

    The Enron Corpus: Where the Email Bodies are Buried? Dr. David Noever Sr. Technical Fellow, PeopleTec, Inc. www.peopletec.com 4901-D Corporate Drive Huntsville, AL 35805 USA [email protected] Abstract To probe the largest public-domain email database for indicators of fraud, we apply machine learning and accomplish four investigative tasks. First, we identify persons of interest (POI), using financial records and email, and report a peak accuracy of 95.7%. Secondly, we find any publicly exposed personally identifiable information (PII) and discover 50,000 previously unreported instances. Thirdly, we automatically flag legally responsive emails as scored by human experts in the California electricity blackout lawsuit, and find a peak 99% accuracy. Finally, we track three years of primary topics and sentiment across over 10,000 unique people before, during and after the onset of the corporate crisis. Where possible, we compare accuracy against execution times for 51 algorithms and report human-interpretable business rules that can scale to vast datasets. Introduction The 2002 Enron fraud case uncovered financial deception in the world’s largest energy trading company and at the time, triggered the largest US bankruptcy and its most massive audit failure [1]. For the previous six years, Fortune magazine had named Enron “America’s most innovative company.” By 1999, Enron was brokering a quarter of all electricity and natural gas deals [1]. Piggybacking on the internet bubble, Enron devised methods to sell everything and own nothing. Problematically, the company could assign its own revenue (mark-to-market) and then bury its losses using off-book debt in shell companies (or Special Purpose Entities called Raptor and Chewco).
