  • Essays on Financial Communication in Earnings Conference Calls
    Essays on Financial Communication in Earnings Conference Calls Xiaoxi Wu This dissertation is submitted for the degree of Doctor of Philosophy September 2019 Department of Accounting and Finance Abstract Earnings conference calls are an important platform of financial communication. They provide researchers with unique opportunities to observe firm managers’ and financial analysts’ interactions and natural communication style in a daily-task environment. Relying on multidisciplinary theories and methods, this dissertation studies financial communication in conference calls from both the managers’ and the sell-side analysts’ perspectives. It consists of three self-contained studies. Chapter 2 focuses on managers’ communication strategies in conference calls. It explores, in the small non-negative earnings surprises setting, whether non-manipulators design communication strategies to separate themselves from earnings manipulators, and whether manipulators pool through obfuscation. Chapters 3 and 4 focus on sell-side analysts’ communication behaviour in conference calls. Chapter 3 examines how analysts’ people skills affect their communication behaviour and relationships with firm management. Chapter 4 applies both qualitative and quantitative discourse analyses and investigates how analysts use linguistic politeness strategies to establish socially desirable identities in publicly accessible analyst-manager interactions. The three studies combined contribute to the accounting literature by furthering our understanding of managers’ and analysts’

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.

  • Conspiracy of Fools”
    Submitted version of review published in GARP Risk Review Review of “Conspiracy of Fools” Joe Pimbley Kurt Eichenwald’s Conspiracy of Fools (Broadway Books, 2005) is a spellbinding account of the rise and fall of Enron. In nearly 700 pages the reader finds answers to “what happened?” and “how did it happen?” Based on retrospective interviews with more than a hundred primary and secondary actors in this drama, the author creates multiple, parallel story lines. He jumps back and forth between these sub-plots in a manner that maintains energy and gives the reader many natural stopping points. The great strengths of Conspiracy are that it’s thorough, extremely well- written, captivating, and, finally, it rings true. The author avoids the easy, simple conclusions that all the executives are “guilty” of crimes or plain greed and that the media-lionized whistle-blower is pure of heart. We see the ultimate outcome as personal tragedies for Jeff Skilling (President) and Ken Lay (CEO) even though they are undeniably culpable. Culpability and guilt are not synonymous, however, and different readers will have widely different judgments to render on these two men. The view of Andrew Fastow is not so murky. He and a handful of his associates did indeed lie, cheat, and steal for personal gain. Fastow’s principle “contribution” to Enron was the creation of structured finance transactions to skirt accounting rules. This one-sentence description doesn’t tell the reader much. Eichenwald gives many examples to flesh out the concept. The story of “Alpine Investors” provides the simplest case. The company wished to sell the Zond Corporation, a wind-farm operator, prior to the closing of Enron’s purchase of Portland General.

Online Peer-to-Peer Payments: PayPal Primes the Pump, Will Banks Follow? As more businesses and individuals turn to the Internet to buy and sell goods, new peer-to-peer payment systems have developed to make these transactions possible.' A peer-to-peer payment system allows one person or entity to transfer money to another.2 The most common of these payment systems are checks and credit cards, but the growth of Internet commerce and the unique demands of the online marketplace have spurred the development of new Internet payment systems.3 While credit cards are useful for making purchases from online merchants, individuals and many small businesses cannot accept credit card payments.4 Checks are not useful in the online market place where buyers and sellers are often unable to determine the reliability or even the identity of each other.5 Making payments by check often causes delays as shipments are held up until a check clears.6 Therefore, a market for Internet peer-to-peer payment systems that are convenient, fast, reliable and safe has emerged Online auctions, in particular the online auction giant eBay, Inc.

  • 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).
