Timeline
Arthur Andersen Founded in Chicago
**1913-01-01** — Arthur E. Andersen establishes the firm that will become one of the dominant accounting partnerships in America. The founding principle is auditor independence, a standard that later proves difficult to preserve under commercial pressure.
Enron Forms Through Deregulated Energy Ambition
**1985-01-01** — The company that becomes Enron grows out of the changing energy market and a favorable regulatory climate. Its executives begin building a business model that rewards financial engineering as much as physical assets.
Andersen Deepens Its Enron Relationship
**1990-01-01** — Arthur Andersen’s Houston office becomes closely tied to the Enron account, combining audit work with a broader consulting presence. That proximity helps create the trust that later becomes part of the scandal.
Sherron Watkins Warns Enron Leadership
**2001-08-15** — Watkins raises internal concerns about accounting practices and the company’s fragility. Her warning becomes one of the most important documented signs that people inside Enron understood the risk.
SEC Opens Formal Inquiry Into Enron
**2001-10-31** — Regulators begin examining Enron’s accounting and disclosures, putting audit work papers and related records under potential legal scrutiny. The inquiry shifts the matter from corporate controversy toward criminal and regulatory exposure.
Arthur Andersen Houston Staff Begin Document Destruction
**2001-11-01** — According to the DOJ’s case theory and trial evidence, Andersen personnel in Houston destroy Enron-related documents after the investigation is underway. The shredding becomes the core factual basis of the obstruction case.

**2002-03-14** — Federal prosecutors charge Arthur Andersen with obstructing the SEC’s Enron investigation. The indictment transforms a professional scandal into a criminal case against one of the world’s largest accounting firms.
Jury Convicts Arthur Andersen
**2002-06-15** — A federal jury finds the firm guilty of obstruction of justice. The conviction triggers an immediate collapse in client confidence and effectively ends Andersen as a major audit firm.
Arthur Andersen Ceases Public Audit Operations
**2002-07-01** — As business evaporates, the firm’s audit practice unravels and thousands of employees face dislocation. The conviction’s commercial consequences arrive before any appellate review can help.
Supreme Court Reverses Andersen Conviction
**2005-05-31** — The U.S. Supreme Court unanimously overturns the conviction, holding that the jury instructions in the obstruction case were flawed. The legal reversal does not restore the firm’s business or reputation.
Congressional and Regulatory Aftermath Continues
**2006-05-25** — The Enron scandal remains central to reforms around auditor independence, document retention, and corporate governance. Sarbanes-Oxley-era oversight becomes the enduring policy response to the broader collapse.
Kenneth Lay Dies Before Sentencing
**2006-07-05** — Lay dies after his conviction but before sentencing, underscoring the human and legal fallout from Enron’s collapse. His death closes one major chapter of accountability while leaving broader institutional lessons unresolved.
