What Was Enron? What Happened and Who Was Responsible

What Was Enron?

Enron was an energy-trading and utility company based in Houston, Texas, that perpetrated one of the biggest accounting frauds in history. Enron's executives employed accounting practices that falsely inflated the company's revenues and, for a time, making it the seventh-largest corporation in the United States. Once the fraud came to light, the company quickly unraveled, and it filed for Chapter 11 bankruptcy in December 2001.

Key Takeaways

  • Enron was an energy company that began to trade extensively in energy derivatives markets.
  • The company hid massive trading losses, ultimately leading to one of the largest accounting scandals and bankruptcy in recent history.
  • Enron executives used fraudulent accounting practices to inflate the company's revenues and hide debt in its subsidiaries.
  • The SEC, credit rating agencies, and investment banks were also accused of negligence—and, in some cases, outright deception—that enabled the fraud.
  • As a result of Enron, Congress passed the Sarbanes-Oxley Act to hold corporate executives more accountable for their company's financial statements.

Understanding Enron

Enron was an energy company formed in 1986 following a merger between Houston Natural Gas Company and Omaha-based InterNorth Incorporated. After the merger, Kenneth Lay, who had been the chief executive officer (CEO) of Houston Natural Gas, became Enron's CEO and chair.

Lay quickly rebranded Enron into an energy trader and supplier. Deregulation of the energy markets allowed companies to place bets on future prices. In 1990, Lay created the Enron Finance Corporation and appointed Jeffrey Skilling, whose work as a McKinsey & Company consultant had impressed Lay, to head the new corporation. Skilling was then one of the youngest partners at McKinsey.

Enron provided a variety of energy and utility services around the world. It's company divided operations in several major departments including:

  • Enron Online: In late 1999, Enron build out it's web-based system to enhance customer functionality market reach.
  • Wholesale Services: Enron offered a variety of energy delivery solutions, with its most robust industry being natural gas. In North America, Enron claimed to deliver almost double the amount of electricity compared to their second tier of competition.
  • Energy Services: Enron's retail unit provided energy around the world, including to Europe in which it expanded retail operations to in 2001.
  • Broadband Services: Enron provided logistical service solutions between content providers and last-mile energy distributors.
  • Transportation Services: Enron developed an innovative, efficient pipeline operation to network capabilities and operate pooling points to connect to third-parties.

However, by leveraging special purpose vehicles, special purpose entities, mark to market accounting, and financial reporting loopholes, Enron became one of the most successful companies in the world. Upon discover of the fraud, the company subsequently collapsed. Enron shares traded as high as $90.75 before the fraud was discovered, but plummeted to around $0.26 in the sell-off after it was revealed.

The former Wall Street darling quickly became a symbol of modern corporate crime. Enron was one of the first big-name accounting scandals, but it was soon followed by the uncovering of frauds at other companies such as WorldCom and Tyco International.

The Enron Scandal

Prior to coming to light, Enron was internally fabricating financial records and falsifying the success of its company. Though the entity did achieve operational success during the 1990s, the company's misdeeds were finally exposed in 2001.

Pre-Scandal

Leading up to the turn of the millennium, Enron's business appeared to be thriving. The company became the largest natural gas provider in North American in 1992, and the company launched EnronOnline, its trading website allowing for better contract management just months before 2000. The company also had rapidly been expanding into international markets, led by the 1998 merger with Wessex Water.

Enron's stock price mostly followed the S&P 500 for most of the 1990's. However, expectations for the company began to soar. In 1999, the company's stock increased 56%. In 2000, it increased an additional 87%. Both returns widely beat broad market returns, and the company was soon trading at a 70x price-earnings ratio.

Early Signs of Trouble

In February 2001, Kenneth Lay stepped down as Chief Executive Officer and was replaced by Jeffrey Skilling. A little more than six months later, Skilling stepped down as CEO in August 2001 with Lay taking over the role again.

Around this time, Enron Broadband reported massive losses. In the company's Q2 2001 earnings report, Lay revealed "in contrast to our extremely strong energy results, this was a difficult quarter in our broadband businesses." In this quarter, the Broadband Services department reported a financial loss of $102 million.

Also around this time, Lay sold 93,000 shares of Enron stock for roughly $2 million while still telling employees via e-mail to continuing buying the stock and predicting significantly higher stock prices. In total, Lay was eventually found to have sold over 350,000 Enron shares for total proceeds greater than $20 million.

During this time, Sherron Watkins had expressed concerns regarding Enron's accounting practices. A Vice President for Enron, she wrong an anonymous letter to Lay expressing her concerns. Watkins and Lay eventually met to discuss the matters in which Watkins delivered a six-page report detailing her concerns. The concerns were presented to an outside law firm in addition to Enron's accounting firm; both agreed there were no issues to be found.

By October 2001, Enron had reported a third quarter loss of $618 million. Enron announced it would need to restate its financial statements from 1997 to 2000 to correct accounting violations.

$63.4 billion

Enron's $63.4 billion bankruptcy was the biggest on record at the time.

Bankruptcy

On Nov. 28, 2001, credit rating agencies reduced Enron's credit rating to junk status, effectively solidifying the company's path to bankruptcy. On the same day, Dynegy, a fellow energy company Enron was attempting to merge with, decided to nix all future conversations and opted against any merger agreement. By the end of the day, Enron's stock price had dropped to $0.61.

Enron Europe was the first domino, filing for bankruptcy after close of business on Nov. 30th. The rest of Enron followed suit on Dec. 2. Early the following year, Enron dismissed Arthur Andersen as its auditor, citing that the auditor had yielded advice to shred evidence and destroy documents.

In 2006, the company sold its last business, Prisma Energy. The next year, the company changed its name to Enron Creditors Recovery Corporation with the intention of repaying back the remaining creditors and open liabilities as part of the bankruptcy process.

Post Bankruptcy/Criminal Charges

After emerging from bankruptcy in 2004, the new board of directors sued 11 financial institutions involved in helping conceal the fraudulent business practices of Enron executives. Enron collected nearly $7.2 billion from these financial institutions as part of legal settlements. The banks included the Royal Bank of Scotland, Deutsche Bank, and Citigroup.

Kenneth Lay pleaded not guilty to eleven criminal charges. He was convicted of six counts of securities and wire fraud and was subject to a maximum of 45 years in prison. However, Lay died on July 5, 2006, before sentencing was to occur.

Jeff Skilling was convicted on 19 of the 28 counts of securities fraud he was charged with in addition to other charges on insider trading. He was sentenced to 24 years and four months in prison, though the U.S. Department of Justice reached a deal with Skilling in 2013 which resulted in ten years being cut off of his sentence.

Andy Fastow and his wife Lea both pleaded guilty to charges against them including money laundering, insider trading, fraud, and conspiracy. Fastow was sentenced to 10 years in prison with no parole in order to testify against other Enron executives. Fastow has since been released from prison.

Causes of the Enron Scandal

Enron went to great lengths to enhance its financial statements, hide its fraudulent activity, and report complex organizational structures to both confuse investors and conceal facts. The causes of the Enron scandal include but are not limited to the factors below.

Special Purpose Vehicles

Enron devised a complex organizational structure leveraging special purpose vehicles (or special purpose entities). These entities would "transact" with Enron, allowing Enron to borrow money without disclosing the funds as debt on their balance sheet.

SPVs do provide a legitimate strategy does allow for companies to temporarily shield a primary company by having a sponsoring company possess assets. Then, the sponsor company can theoretically secure cheaper debt than the primary company (assuming the primary company may have credit issues). There are also legal protection and taxation benefits to this structure.

The primary issue with Enron was the lack of transparency surrounding the use of SPVs. The company would transfer its own stock to the SPV in exchange for cash or a note receivable. The SPV would then use the stock to hedge an asset against Enron's balance sheet. Once the company's stock started losing its value, it no longer provided sufficient collateral that could be exploited by being carried by an SPV.

Inaccurate Financial Reporting Practices

Enron inaccurately depicted many contracts or relationships with customers. By collaborating with external parties such its auditing firm, it was able to record transactions incorrectly, not only not in accordance with GAAP but also not in accord with agreed to contracts.

For example, Enron recorded one-time sales as recurring revenue. In addition, the company would intentionally maintain an expired deal or contract through a specific time period to avoid having to record a write-off during a given period.

Poorly Constructed Compensation Agreements

Many of Enron's financial incentive agreements with employees were driven on short-term sales and quantities of deals closed (without consideration for the long-term validity of the deal). In addition, many incentives did not factor in the actual cash flow from the sale. Employees also receive compensation tied to the success of the company's stock price, while upper management often received large bonuses tied to success in financial markets.

Part of this issue was the very rapid rise of Enron's equity success. On Dec. 31, 1999, the stock closed at $44.38. Just three months later, it closed on March 31, 2000 at $74.88. With the stock hitting $90 by the end of 2000, the massive profits some employees received only fueled further interest in obtaining equity positions in the company.

Lack of Independent Oversight

Many external parties learned to know Enron's fraudulent practices, but their financial involvement with the company likely caused them to not intervene. Arthur Andersen, Enron's accounting firm, received many jobs and financial compensation in return for their service. Investment bankers collected fees from Enron's financial deals. Buy-side analysts were often compensated to promote specific ratings in exchange for stronger relationships between Enron and those institutions.

Unrealistic Market Expectations

Both Enron Energy Services and Enron Broadband were poised to be successful due to the emergence of the Internet and heightened retail demand. However, Enron's over-optimism resulted in the company over-promising on services and timelines that were simply not realistic.

Poor Corporate Governance

The ultimate downfall of Enron was the result of overall poor corporate leadership and corporate governance. Former Vice President of Corporate Development Sherron Watkins is noted for speaking out about various financial treatments as they were occurring. However, top management and executives intentionally disregarded and ignored concerns. This tone from the top set the precedent across accounting, finance, sales, and operations.

In the early 1990's, Enron was the largest seller of natural gas in North America. Ten years later, the company no longer existed due to its accounting scandal.

The Role of Mark-to-Market Accounting

One additional cause of the Enron collapse was mark-to-market accounting. Mark to market accounting is a method of valuating a long-term contract using fair market value. At any point, the long-term contract or asset could fluctuate in value; in this case, the reporting company would simply "mark" their financial records up or down to reflect the prevailing market value.

There are two conceptual issues with mark-to-market accounting, both of which Enron took advantage of. First, mark-to-market accounting relies very heavily on management estimation. Consider a long-term, complex contracts requiring the international distribution of several forms of energy. Because these contracts were not standardized to common contracts, it was easy for Enron to artificially inflate the value of the contract because it was difficult to appropriate determine the market value.

Second, mark-to-market accounting requires companies to periodically evaluate the value and likelihood that revenue will be collected. Should companies fail to continually evaluate the value of the contract, it may easily overstate the expected revenue to be collected.

For Enron, mark-to-market accounting allowed the firm to recognize it's multi-year contracts upfront and report 100% of income in the year the agreement was signed, not when the service would be provided or cash collected. This form of accounting allowed Enron to report unrealized gains that inflated its income statement, allowing the company to appear much more profitable than its cash flow truly was.

What Happened to Enron

The Enron bankruptcy, at $63.4 billion in assets, was the largest on record at the time. The company's collapse shook the financial markets and nearly crippled the energy industry. While high-level executives at the company concocted the fraudulent accounting schemes, financial and legal experts maintained that they would never have gotten away with it without outside assistance. The Securities and Exchange Commission (SEC), credit rating agencies and investment banks were all accused of having a role in enabling Enron's fraud.

Initially, much of the finger-pointing was directed at the SEC, which the U.S. Senate found complicit for its systemic and catastrophic failure of oversight. The Senate's investigation determined that had the SEC reviewed any of Enron’s post-1997 annual reports, it would have seen the red flags and possibly prevented the enormous losses suffered by employees and investors.

The credit rating agencies were found to be equally complicit in their failure to conduct proper due diligence before issuing an investment-grade rating on Enron’s bonds just before its bankruptcy filing. Meanwhile, the investment banks—through manipulation or outright deception—had helped Enron receive positive reports from stock analysts, which promoted its shares and brought billions of dollars of investment into the company. It was a quid pro quo in which Enron paid the investment banks millions of dollars for their services in return for their backing.

Enron reported total company revenue of:


  • $13.2 billion in 1996
  • $20.3 billion in 1997
  • $31.2 billion in 1998
  • $40.1 billion in 1999
  • $100.8 billion in 2000

The Role of Enron's CEO

By the time Enron started to collapse, Jeffrey Skilling was the firm's CEO. One of Skilling's key contributions to the scandal was to transition Enron's accounting from a traditional historical cost accounting method mark-to-market accounting for which the company received official SEC approval in 1992.

Skilling advised the firm's accountants to transfer debt off of Enron's balance sheet to create an artificial distance between the debt and the company that incurred it. Enron continued to use these accounting tricks to keep its debt hidden by transferring it to its subsidiaries on paper. Despite this, the company continued to recognize revenue earned by these subsidiaries. As such, the general public and, most importantly, shareholders were led to believe that Enron was doing better than it actually was, despite the severe violation of GAAP rules.

Skilling abruptly quit in August 2001 after less than a year as chief executive—and four months before the Enron scandal unraveled. According to reports, his resignation stunned Wall Street analysts and raised suspicions, despite his assurances at the time that his departure had “nothing to do with Enron.”

Both Skilling and Kenneth Lay were tried and found guilty of fraud and conspiracy in 2006. Other executives plead guilty. Lay died in prison shortly after sentencing and Skilling served twelve years, by far the longest sentence of any of the Enron defendants.

The Legacy of Enron

In the wake of the Enron scandal, the term "Enronomics" came to describe creative and often fraudulent accounting techniques that involve a parent company making artificial, paper-only transactions with its subsidiaries to hide losses the parent company has suffered through other business activities.

Parent company Enron had hidden its debt by transferring it (on paper) to wholly-owned subsidiaries—many of which were named after Star Wars characters—but it still recognized revenue from the subsidiaries, giving the impression that Enron was performing much better than it was.

Another term inspired by Enron's demise was "Enroned," slang for having been negatively affected by senior management's inappropriate actions or decisions. Being "Enroned" can happen to any stakeholder, such as employees, shareholders, or suppliers. For example, if someone has lost their job because their employer was shut down due to illegal activities that they had nothing to do with, they have been "Enroned."

As a result of Enron, lawmakers put several new protective measures in place. One was the Sarbanes-Oxley Act of 2002, which serves to enhance corporate transparency and criminalize financial manipulation. The rules of the Financial Accounting Standards Board (FASB) were also strengthened to curtail the use of questionable accounting practices, and corporate boards were required to take on more responsibility as management watchdogs.

What Did Enron Do That Was So Unethical?

Enron used special purpose entities to hide debt off of its balance sheet and mark-to-market accounting to overstate revenue. In addition, it ignored internal advisement against these practices knowing that its publicly disclosed financial position was incorrect.

How Big was Enron?

With shares trading for around $90/each, Enron was once worth about $70 billion. Lead up to its bankruptcy, the company employed over 20,000 employees. The company also reported over $100 billion of company-wide net revenue (though this figure has since been determined to be incorrect).

Who Was Responsible for the Collapse of Enron?

Several key members of the executive team are often noted as being responsible for the fall of Enron. The executives includes Kenneth Lay (founder and former Chief Executive Officer), Jeffrey Skilling (former Chief Executive Office replacing Lay), and Andrew Fastow (former Chief Financial Officer).

Does Enron Exist Today?

As a result of its financial scandal, Enron ended its bankruptcy in 2004. The name of the entity officially changed to Enron Creditors Recovery Corp., and the company's assets were liquidated and reorganized as part of the bankruptcy plan. It's last business, Prisma Energy, was sold in 2006.

The Bottom Line

At the time, Enron's collapse was the biggest corporate bankruptcy to ever hit the financial world (since then, the failures of WorldCom, Lehman Brothers, and Washington Mutual have surpassed it). The Enron scandal drew attention to accounting and corporate fraud as its shareholders lost tens of billions of dollars in the years leading up to its bankruptcy, and its employees lost billions more in pension benefits. Increased regulation and oversight have been enacted to help prevent corporate scandals of Enron's magnitude. However, some companies are still reeling from the damage caused by Enron.
