Dan Boyle

Daniel O. Boyle served as Vice President in Enron’s Global Finance unit, where he worked directly under Chief Financial Officer Andrew Fastow. In November 2004, Boyle was convicted on multiple counts related to the Nigerian Barge transaction, a year-end 1999 scheme in which Enron arranged for Merrill Lynch to temporarily purchase an interest in electricity-generating barges so the company could fraudulently book $12 million in revenue. The conviction made Boyle one of the first Enron employees to face a jury in connection with the scandal.

Boyle’s case stands apart from those of his co-defendants for several reasons. While the four Merrill Lynch executives convicted alongside him successfully appealed their convictions in 2006 based on flaws in the honest services fraud theory, Boyle declined to appeal and served his full 46-month sentence at a federal prison camp in Texas. At sentencing, U.S. District Judge Ewing Werlein Jr. characterized Boyle as a low-level employee following orders from more culpable superiors and gave him the minimum sentence allowable under federal guidelines. Boyle was the only defendant who expressed genuine remorse, telling the court: “I am the only one responsible for my acts and omissions… I’m truly sorry.”

The Nigerian Barge Transaction

Origins of the Scheme

In late 1999, Enron needed to meet year-end earnings targets. The company owned an interest in three electricity-generating power barges moored off the coast of Nigeria, which it had unsuccessfully attempted to sell throughout the year. With the December 31 deadline approaching and no legitimate buyer in sight, Enron’s Global Finance team arranged for Merrill Lynch to serve as a temporary purchaser, allowing Enron to record the transaction as a $12 million profit.

The transaction was not a genuine sale. Prosecutors established that Enron made a secret promise to get Merrill Lynch out of the deal within six months with a guaranteed return of approximately 20 percent. This guarantee transformed what appeared on Enron’s books as a sale into what should have been recorded as a loan. The distinction mattered enormously: a loan would not generate revenue, would appear as a liability rather than income, and would not help Enron meet its earnings targets.

Boyle’s Role in the Deal

Boyle played an active operational role in structuring and executing the Nigerian Barge transaction. He scripted the phone call that set up the side deal with Merrill Lynch, crafting the language that would convey the guarantee without creating obvious documentation of fraud. His involvement went beyond mere execution — Boyle requested a bonus based on his work on the deal, a detail prosecutors later cited as evidence he understood the transaction’s true nature.

The documentary evidence against Boyle proved particularly damaging at trial. An email he wrote stated that the deal with Merrill “was to get them a total annualized return of roughly 20 percent,” adding that Merrill was expecting to receive $7.525 million when it was bought out of the deal on June 30, 2000. Another email acknowledged that Merrill Lynch participated only because of “personal assurances” from Enron’s top executives that the bankers would be removed from the investment by mid-2000.

The Secret Guarantee

The prosecution’s case centered on proving that Enron had made a binding promise to buy back the barges or find another purchaser. Eric Boyt, an in-house accountant at Enron, provided key testimony against Boyle. According to Boyt, it was Boyle who first told him about the Merrill Lynch deal and the secret side guarantee that made the purported sale an accounting sham. Boyt testified that immediately after a conference call in which Fastow participated, Boyle informed him that Fastow had guaranteed a buyback with a 15 percent return in six months if another buyer could not be found.

In June 2000, LJM2, a partnership controlled by Fastow, purchased the barges from Merrill Lynch, giving the bank its $7 million investment back plus a premium exceeding $500,000. This buyback fulfilled the secret guarantee and demonstrated that the December 1999 transaction had never been a genuine sale. The money trail proved what Boyle’s emails had documented: Merrill Lynch was always going to be made whole, turning the supposed asset sale into a round-trip transaction designed solely to manipulate Enron’s earnings.

Criminal Prosecution

Initial Charges

Dan Boyle was initially charged in October 2003 with conspiracy to commit wire fraud, carrying a maximum sentence of five years in prison. The charges linked him directly to the Nigerian Barge scheme and alleged that he had participated in a conspiracy to defraud Enron’s investors by manipulating the company’s financial statements.

The Superseding Indictment

In June 2004, a federal grand jury in Houston returned a superseding indictment that significantly expanded the charges against Boyle. The new indictment added two wire fraud charges related to the Nigerian Barge transaction and, critically, a count of making false statements to congressional investigators. If convicted on all charges, Boyle faced up to 20 years in prison.

The false statement charge arose from Boyle’s testimony to a congressional committee investigating Enron’s collapse. During that testimony, Boyle falsely stated that in December 1999, he knew of no guarantees of a buyout made to Merrill Lynch. This claim directly contradicted the documentary evidence, including his own emails documenting the guaranteed return, and the testimony of colleagues who said Boyle had informed them of the guarantee.

Trial and Conviction

The Nigerian Barge case went to trial in September 2004, marking the first criminal trial arising from the Enron scandal. Boyle and fellow Enron accountant Sheila Kahanek were the first employees from Enron’s ranks to face a jury. They were tried alongside four Merrill Lynch executives: Daniel Bayly, James Brown, Robert Furst, and William Fuhs.

In November 2004, the jury returned its verdict. Five of the six defendants were convicted. Boyle was found guilty on all charges against him: conspiracy to commit wire fraud, conspiracy to falsify books, records and accounts, and making false statements to congressional investigators. Only Kahanek was acquitted, the jury finding insufficient evidence that she had knowingly participated in the fraud despite her role as an accountant on the transaction.

Sentencing

Judge Werlein’s Assessment

U.S. District Judge Ewing Werlein Jr. sentenced Boyle in May 2005. In determining the appropriate punishment, Judge Werlein looked past Boyle’s formal title to assess his actual culpability within Enron’s hierarchy. The judge concluded that Boyle had been a relatively low-level employee doing the bidding of far more culpable superiors, specifically identifying Andrew Fastow and Chief Accounting Officer Richard Causey as the executives truly responsible for the fraud.

This assessment reflected the evidence presented at trial, which showed that while Boyle executed key aspects of the transaction, the scheme itself originated with and was directed by senior executives. Fastow had made the oral commitment to Merrill Lynch’s leadership; Boyle’s role was to implement that commitment in the face of resistance from Merrill’s bankers and to document terms that would satisfy the bank while concealing the guarantee from auditors.

The Sentence

Judge Werlein sentenced Boyle to 46 months (3 years and 10 months) in federal prison and imposed a $320,000 fine. This represented the minimum sentence allowable under federal sentencing guidelines for his offenses. The judge explicitly noted that the relatively lenient treatment reflected Boyle’s subordinate position and the greater culpability of those who directed his actions.

Remorse and Community Support

Boyle distinguished himself from his co-defendants through his conduct at sentencing. In a short statement to the court, he apologized for his role in the crimes, accepting personal responsibility without attempting to shift blame. Multiple news reports noted that Boyle was the only defendant who appeared genuinely repentant about pushing through the sham sale.

Boyle also demonstrated substantial community ties. Several dozen people came to court to support him at sentencing, the only Houston-area defendant to draw such a crowd. This community presence suggested that whatever crimes Boyle had committed at Enron, his life outside the company had earned him loyal friends and supporters.

Appeals and Aftermath

The Decision Not to Appeal

In a choice that proved fateful, Boyle declined to appeal his conviction. He reported to a federal prison camp in Texas and began serving his 46-month sentence while his co-defendants pursued their appeals through the Fifth Circuit Court of Appeals.

The Merrill Lynch Reversals

In August 2006, a three-judge panel of the Fifth Circuit overturned the fraud and conspiracy convictions against the four former Merrill Lynch executives. The appellate court found that prosecutors had improperly applied the honest services fraud theory, which the court concluded did not reach the conduct at issue. William Fuhs’ convictions were also overturned due to insufficient evidence.

The reversals created an unusual situation. Boyle’s conviction for the same underlying conduct remained intact because he had not appealed, while his co-defendants walked free. The honest services fraud issues that invalidated the Merrill Lynch convictions might well have provided grounds for reversing Boyle’s conviction had he pursued an appeal. However, Boyle’s additional conviction for making false statements to Congress, a charge that did not rely on the honest services fraud theory, might have survived appellate review regardless.

Service and Release

Boyle served his full sentence at a federal prison camp in Texas. Unlike cooperating witnesses such as Michael Kopper and Ben Glisan, whose sentences were shaped by their assistance to prosecutors, Boyle served out the term imposed by Judge Werlein without seeking to reduce it through cooperation.

Relationship to Senior Executives

Andrew Fastow

Boyle worked directly under CFO Andrew Fastow in the Global Finance unit. The Department of Justice alleged that Fastow, Glisan, Boyle, and others “devised schemes to fraudulently manipulate Enron’s reported financial results so that the company would appear more successful than it was.” Fastow’s oral guarantee to Merrill Lynch’s leadership created the framework for the Nigerian Barge fraud; Boyle’s job was to execute that guarantee while maintaining the appearance of a legitimate sale.

Ben Glisan Jr.

Ben Glisan, who succeeded Jeffrey McMahon as Enron’s Treasurer in May 2000, executed Enron’s buyback of the barges from Merrill Lynch, fulfilling the oral guarantee Fastow had made. When LJM2 purchased the barges from Merrill Lynch in June 2000, completing the fraudulent round-trip, Glisan was serving as Treasurer and overseeing Enron’s treasury operations. Both Boyle and Glisan worked within Fastow’s orbit at Global Finance, though Glisan’s seniority as Treasurer gave him broader responsibilities.

Richard Causey

Judge Werlein identified Chief Accounting Officer Richard Causey as one of the executives more responsible for the Nigerian Barge fraud than Boyle. Causey was responsible for Enron’s financial reporting and would have approved the accounting treatment that allowed Enron to book the transaction as a sale rather than a loan. Boyle was expected to testify against Causey, as well as former Chairman Ken Lay and former CEO Jeffrey Skilling, when their trial began in January 2006.

Historical Significance

The First Enron Trial

The Nigerian Barge prosecution holds a significant place in the history of the Enron scandal as the first criminal case to reach trial. The November 2004 convictions demonstrated that the Enron Task Force could successfully prosecute individuals for their roles in the company’s fraud, establishing important precedents for the larger trials to follow.

Implications for Honest Services Fraud

The appellate reversal of the Merrill Lynch convictions had broader implications for federal fraud prosecutions. The Fifth Circuit’s critique of the honest services fraud theory as applied in the Nigerian Barge case contributed to an ongoing legal debate that culminated in the Supreme Court’s 2010 decision in Skilling v. United States, which significantly narrowed the scope of honest services fraud to cases involving bribes and kickbacks.

Boyle’s case thus represents both a successful prosecution at the trial level and a cautionary tale about the limits of criminal fraud theories. Had Boyle appealed, the outcome of his case might have been different, but his decision to accept responsibility and serve his sentence meant that he bore consequences his co-defendants ultimately avoided.

Legal Status

Dan Boyle was convicted in November 2004 of conspiracy to commit wire fraud, conspiracy to falsify books and records, and making false statements to congressional investigators. He was sentenced in May 2005 to 46 months in federal prison, the minimum under sentencing guidelines, and fined $320,000. Boyle did not appeal his conviction and served his full sentence at a federal prison camp in Texas. His co-defendants’ convictions were later reversed on appeal, but Boyle’s conviction stands as the only final judgment from the first Enron criminal trial.
