Accounting Department

Enron’s Accounting department was the corporate function responsible for financial reporting, controller operations, and accounting standards compliance across the company’s global business units. Led by Chief Accounting Officer Richard Causey, the department operated a matrix structure with both a corporate accounting team and distributed controllers embedded within each major business unit. Key figures included Causey as CAO, Ben Glisan as Treasurer (promoted from the Structured Finance Group), and Wesley Colwell as CAO of Enron North America. The department’s accounting practices, including mark-to-market valuations, special purpose entity accounting, and reserve account manipulation, became central to the fraud that destroyed the company.

The principal accounting executives – Causey, Glisan, and Colwell – do not have personal PST email archives in the Enron corpus. This is significant: the key accounting figures’ direct email accounts were either never released to FERC, withheld due to ongoing legal proceedings, or segregated for evidentiary purposes. All findings about their activities come from emails mentioning them sent by other employees, meeting calendar entries, and corporate announcements forwarded through the organization. However, DOJ and SEC enforcement documents provide extensive detail about the department’s fraudulent activities, making this one of the most thoroughly documented aspects of Enron’s collapse through secondary sources.

Organizational Structure

Chief Accounting Officer

Richard Causey was promoted to Chief Accounting Officer in July 1999 as part of a major organizational restructuring announced by the Office of the Chairman. The announcement, dated July 1, 1999, described fundamental changes intended to capture opportunities in “a new economy based on intellectual capital and the compelling economics of networks.” The restructuring reorganized Enron around its wholesale, retail, and communications businesses, with Causey responsible for the accounting and financial reporting infrastructure that supported them all.

A subsequent announcement on July 26, 1999, clarified the breadth of Causey’s mandate: “With the expansion of our global businesses and the acceleration of our financial activities, Rick will focus on the leadership of Enron’s accounting and financial reporting activities, as well as overseeing risk management systems, Y2K preparations and our SAP implementation.” This scope made the CAO responsible not only for accounting judgments but also for the operational systems that tracked and reported Enron’s financial position.

Matrix Structure and Business Unit Controllers

The CAO organization operated through a matrix model, with corporate accounting staff supplemented by controllers embedded in each major business unit. A CAO Staff Meeting invitation from February 2, 2000, reveals the breadth of this structure: attendees included Sally Beck (Vice President of Global Risk Management Operations, reporting to Causey), Wes Colwell, Fernley Dyson (London), Rod Hayslett, and controllers from Enron Capital and Trade, Enron Energy Services, Azurix, GPG, and Enron Development. This distribution indicated that accounting oversight extended across every major operating entity.

An “Operations Business Controller Offsite” organized by Sally Beck in September 2000 further documented the distributed controller structure, with business unit controllers meeting to coordinate accounting practices across the organization.

Global Risk Management Operations

On January 17, 2000, Enron announced the creation of a global risk management operations function under Sally Beck’s direction, with Beck reporting directly to Causey. By July 2000, the Global Strategic Sourcing organization had also been placed under Causey’s authority, consolidating oversight of critical operational functions beneath the CAO.

Key Personnel

Ben Glisan – Treasurer

Ben Glisan was promoted from Vice President and head of Enron Global Finance’s Structured Finance business to Vice President and Treasurer of Enron Corp. on May 22, 2000, succeeding Jeff McMahon. The corporate announcement explicitly noted his prior career path: “Ben joined Enron in 1996 from Arthur Andersen where he was responsible for managing structured transactions with Enron. Prior to Arthur Andersen, Ben worked at Coopers & Lybrand providing accounting and finance services principally to financial institutions.”

This career trajectory – from external auditor managing Enron’s structured transactions at Arthur Andersen to internal executive designing and implementing those transactions at Enron – created a clear conflict of interest. Glisan’s deep familiarity with the accounting rules governing structured finance, gained while auditing Enron, was redirected toward structuring deals that appeared to comply with those rules but did not. The SEC later charged Glisan with violations of anti-fraud, lying-to-auditors, periodic reporting, books and records, and internal controls provisions of federal securities laws.

Wesley Colwell – CAO of Enron North America

Wesley Colwell joined Enron in late 1999 and became Chief Accounting Officer of Enron North America in February 2000, overseeing accounting for Enron’s oil and gas trading business. Email evidence shows Colwell participating in meetings with Causey and other executives on international accounting matters. A January 24, 2000, calendar entry records a meeting in EB 5023 “w/ Rick Causey, Rick Buy, Wes Colwell & Ted Murphy re: London trip update,” and a same-day conference call between Colwell, Ted Murphy, and John Sorrells in London.

Colwell’s role became central to the fraud. According to SEC enforcement documents, he and others at Enron “engaged in a wide ranging scheme to defraud by manipulating Enron’s publicly reported earnings through a variety of devices designed to produce materially false and misleading financial results, including the misuse of reserve accounts, concealment of losses, inflation of asset values, and deliberate use of improper accounting treatment for transactions.”

Sally Beck – Risk Management Operations

Sally Beck served as Vice President of Global Risk Management Operations, reporting to Causey. She oversaw trading operations controls and risk management infrastructure across Enron’s global wholesale energy businesses. Her participation in CAO Staff Meetings and her organization of business controller offsites positioned her as a senior figure in the accounting and operations hierarchy.

Accounting Practices and Techniques

Mark-to-Market Accounting

Mark-to-market accounting was Enron’s signature financial reporting technique, allowing the company to record the projected future value of long-term contracts as current revenue. The Accounting department implemented this approach across business units, including international operations where it raised complex cross-jurisdictional issues.

An email from Sandeep Kohli dated January 24, 2000, illustrates the practical challenges of implementation. Kohli discussed applying mark-to-market to Indian transactions, noting the disconnect between US GAAP and Indian accounting standards: “What I am concerned about is that there will be an Enron India (EIPL) account in India based on Indian GAAP, and upon consolidation there will be a US GAAP accounting in the US. It is here that we would like to have mark-to-market accounting.” He also flagged the tax consequences: “When we m-t-m the transaction in the US there will be a tax accruing in the year of m-t-m (say 2000). However, in India, as a result of the accrual accounting, there will not be any in[come]…”

This correspondence reveals a department actively extending mark-to-market treatment to new geographies and asset classes, with full awareness of the accounting complexities involved.

Reserve Account Manipulation

The most damaging accounting manipulation attributed to the department involved the systematic misuse of reserve accounts within Enron North America. Under Colwell’s direction as CAO of ENA, more than $400 million in earnings were deferred into reserve accounts during the year 2000. During the first and second quarters of 2001, Colwell and others used these same reserve accounts to mask over $1 billion in losses associated with Enron’s retail energy business, Enron Energy Services.

This manipulation was internal accounting journal entry work that would not necessarily generate email traffic, explaining the limited direct evidence in the corpus. The SEC documented the practice through forensic accounting analysis of Enron’s books and records.

Special Purpose Entity Accounting

The Accounting department was responsible for determining whether Enron’s numerous special purpose entities met the accounting requirements for off-balance-sheet treatment. Causey, as CAO, was the executive charged with ensuring that SPE structures complied with Generally Accepted Accounting Principles, yet the DOJ characterized him as “a principal architect and operator of the scheme to manipulate Enron’s reported earnings” through those same structures.

The Raptor Structures

The Raptor structures represent the Accounting department’s most consequential failure. These four SPE vehicles, created in partnership with Andrew Fastow’s LJM2 fund between 1999 and 2000, were designed to hedge Enron’s merchant investment portfolio. The department approved accounting treatment that kept the Raptors off Enron’s balance sheet, concealing hundreds of millions of dollars in investment losses.

Project Raptor Meetings

Calendar entries from March 30, 2000, document early coordination between the Accounting department and other key players. A “Project Raptor Meeting” with Glisan was held at the law firm Vinson & Elkins at 9:00 AM, followed by a meeting between “Causey, Fastow & Glisan re: Project Rapture” at 12:30 PM. The presence of Causey, Fastow, and Glisan together at V&E offices during the Raptor structures’ formative period shows the CAO’s direct involvement from inception.

The Four Raptor Entities

The Raptor structures consisted of four pairs of “top tier” and “bottom tier” entities:

Each top-tier entity was nominally controlled by LJM2, while the bottom-tier entities were structured to consolidate with Enron under certain conditions. The fundamental flaw was that the vehicles were capitalized primarily with Enron’s own stock, creating a circular dependency that guaranteed collapse if the stock declined.

Raptor Unwind

On September 28, 2001, the Raptor structures were unwound. An email from Essie Locklear dated October 8, 2001, described the mechanics in detail: “Each of the ’top tier’ Raptor entities (Harrier, Roadrunner, Pronghorn, and Grizzly) ‘purchased’ from LJM the membership interest that LJM owned in the ‘bottom tier’ Raptor entities (Talon, Bobcat, Porcupine, and Timberwlf, respectively). Harrier paid $6 mil, Roadrunner and Grizzly each paid $15 mil, and Pronghorn paid $1,000.”

The result was devastating: “A total book loss of around $600 mil was recorded.” For tax purposes, the transactions were to be treated as “merely a final payment made by Enron Corp. on a contingent debt instrument,” revealing the extent to which the Raptor structures had always been, in substance, Enron’s own obligations.

The Arthur Andersen Relationship

Embedded Auditor Model

Arthur Andersen served as Enron’s external auditor while maintaining an unusually close working relationship with the Accounting department. Evidence from the email corpus shows ongoing collaboration: a May 11, 1999, calendar entry documents an “Arthur Andersen Document Standards Review” involving Enron staff Bob Schultz, Jeff Sorenson, and Mary Solmonson alongside Andersen representatives K. C. Evans and Kate Agnew. A May 19, 1999, entry records an “Arthur Andersen Legal Review” with Casey Evans.

The relationship between the Accounting department and Arthur Andersen was shaped by the revolving door between the two organizations. Causey himself had come to Enron from Andersen. Glisan had managed structured transactions with Enron as an Andersen professional before joining the company. David Duncan, Andersen’s lead engagement partner for Enron, had been Causey’s colleague at the firm. These personal connections contributed to a lack of auditor independence that allowed the Accounting department’s aggressive practices to go unchallenged.

Breakdown in November 2001

The auditor-client relationship collapsed in early November 2001 when Arthur Andersen refused to provide the required reviews of interim financial information for Enron’s Form 10-Q filings with the SEC. An email from Nora Dobin dated November 7, 2001, reported the crisis to Enron’s legal team: “I understand that AA [Arthur Andersen] may not provide the review of interim financial information that the SEC requires to be obtained in respect of Form 10-Q filings.”

Dobin outlined the cascading consequences: “Failure to deliver the 10-Q constitutes an Event of Default under the revolver if the failure continues for more than 30 days after ENE has received notice thereof by the Paying Agent.” She noted a possible workaround – Enron could “send it to the banks as confidential information (to comply with Regulation FD) within the required time period and satisfy the covenant” – but the loss of Andersen’s imprimatur signaled the end of the Accounting department’s ability to produce credible financial statements.

The Collapse

The unraveling of the Accounting department’s work accelerated through October and November 2001, as the structures and practices it had approved came under scrutiny from regulators, investors, and the media.

On September 28, 2001, the Raptor structures were unwound, generating approximately $600 million in book losses that could no longer be hidden. When Enron announced its third-quarter results on October 16, 2001, the company disclosed a $544 million after-tax charge related to the Raptor unwind, along with a $1.2 billion reduction in shareholder equity. These disclosures prompted the SEC to open a formal investigation.

In November 2001, Enron restated its financial results going back to 1997, acknowledging that the Chewco partnership had never met the requirements for off-balance-sheet treatment. The restatement reduced reported net income by $586 million over the restated period. On November 7, 2001, Arthur Andersen’s refusal to sign off on the Form 10-Q removed the last pillar of the Accounting department’s credibility. On December 2, 2001, Enron filed for Chapter 11 bankruptcy.

Timeline

Legal Consequences

The Accounting department’s three most senior figures all faced criminal or civil enforcement actions:

Richard Causey pleaded guilty to securities fraud on December 28, 2005, admitting to conspiring with senior management to make false and misleading statements in Enron’s SEC filings and analyst calls. He was sentenced to 66 months in federal prison, agreed to forfeit $1.25 million, paid a $25,000 fine, and surrendered all deferred compensation claims from Enron. He agreed to cooperate with the Enron Task Force, though his cooperation came too late to serve as a witness in the Lay-Skilling trial.

Ben Glisan pleaded guilty on September 10, 2003, to a single count of conspiracy to commit wire and securities fraud. He was immediately taken into custody and sentenced to five years in federal prison, becoming the first Enron executive imprisoned. He forfeited approximately $938,000 and waived refund claims for $412,000 in income taxes, amounts corresponding to his proceeds from the Southampton transaction. Unlike other cooperating executives, Glisan went directly to prison without a cooperation agreement.

Wesley Colwell settled with the SEC for a $500,000 fine, lost his CPA license, and was barred from serving as an officer or director of any publicly traded company. The SEC alleged that he had manipulated Enron’s publicly reported earnings through misuse of reserve accounts, concealment of losses, inflation of asset values, and deliberate use of improper accounting treatment for transactions.

Data Quality Notes

The absence of personal email archives for Causey, Glisan, and Colwell represents a significant limitation in the available primary source material. All findings about these executives come from indirect evidence: emails mentioning them sent by other employees, calendar entries, and corporate announcements. Despite this limitation, DOJ and SEC enforcement documents provide extensive forensic detail about the department’s activities. The period between the Raptor structures’ creation in early 2000 and their unwind in September 2001 has limited accounting-specific emails in the corpus, though the October 2001 unwind email provides detailed evidence of the structures’ mechanics.
