Mark-to-market accounting is itself illegal.
U.S. GAAP allows fair-value treatment in defined settings. The Enron cases attacked unsupported valuations and related-party hedges, not the existence of the standard.

Quick answers
When did Enron go bankrupt?
Enron filed for Chapter 11 protection on 2 December 2001 in the Southern District of New York bankruptcy court, after restatements, an SEC inquiry, and the collapse of a proposed Dynegy merger.
Who was convicted?
Jeffrey Skilling was convicted in 2006 in the Southern District of Texas. Andrew Fastow pleaded guilty in 2004. Kenneth Lay was convicted in 2006 but died before sentencing; that conviction was vacated. Other employees and bankers faced separate cases.
What happened to Arthur Andersen?
A Houston jury convicted Andersen in 2002 of obstruction of justice related to document destruction. The Supreme Court reversed the conviction in 2005, but the firm had already lost its public-company audit practice.
What is the Powers Report?
A February 2002 report by a special committee of Enron's board, chaired by William C. Powers Jr., describing the LJM partnerships, Raptor structures, and board oversight failures. It is a primary public narrative of the accounting.
How did Sarbanes-Oxley relate to Enron?
Congress passed the Sarbanes-Oxley Act in 2002 after Enron and related collapses, including WorldCom. The Act created the PCAOB, expanded auditor-independence rules, and required executive certification of filings.
What does mark-to-market mean in this case?
Enron booked estimated fair values of certain long-term contracts as current earnings. Courts and the Powers committee treated the abuse as lying in unsupported valuations and related-party hedges, not in the mere existence of fair-value accounting.
The Houston trial ended the main criminal story. Appeals, the Andersen reversal, and twenty years of SOX practice are the aftermath.
Myths persist about what mark-to-market is and about whether Andersen was found innocent in a way that restores the firm.
Still open
- How to teach mark-to-market — Fair-value accounting remains legal and necessary in many books. The open pedagogical question is how to separate Enron's abuse from the tool.
- Audit-market concentration — The loss of Andersen left four global networks. Whether that concentration is safer is still a live regulatory debate.
- Lay's vacated verdict — Death abated the conviction. Historians treat the jury findings as a record of what was proved, not as a surviving judgment.
- Estate recoveries vs. employee harm — Creditor recoveries and employee 401(k) losses are different ledgers; they are still sometimes added as if they were one number.
- Honest-services after Skilling — How far federal prosecutors may go on intangible-rights theories remains a doctrinal argument the 2010 decision did not end.
Myth vs record
Arthur Andersen was exonerated and survived.
The Supreme Court reversed the conviction in 2005, but the firm had already collapsed as a public-company auditor in 2002.
Kenneth Lay's conviction still stands.
Lay died before sentencing. Under the abatement doctrine the district court vacated the conviction.
Enron was only a California energy-crisis story.
California trading is part of the history; the criminal core in Houston was corporate accounting, SPEs, and false statements to investors and banks.
Local notes
Journal footnotes and the 2001 scoop cycle
English-language business desks learned to read related-party footnotes after Enron. That habit still shows up in later coverage of SPEs and non-GAAP earnings.
Fortune to Hollywood
The magazine-to-book-to-film pipeline made Enron a narrative property in U.S. and U.K. media, sometimes at the expense of the Powers Report's dryer map.
SOX as a London comparison
FT writers still use Enron when comparing U.S. certification rules with U.K. Combined Code and later audit-reform papers -- a transatlantic teaching pair.
The aftermath is a statute that still binds issuers, an audit market with one fewer firm, and a name that means the earnings were the story.
