Enron
Enron Accounting Fraud and Collapse
Estimated impact: $74B
Enron used special purpose entities and mark-to-market accounting to hide billions in debt and inflate profits. A culture of intimidation silenced internal dissent while the board repeatedly approved complex off-balance-sheet structures they did not fully understand, resulting in the largest corporate bankruptcy at the time.
Decision context
Whether to approve increasingly complex off-balance-sheet financing structures proposed by CFO Andrew Fastow, despite their opacity and conflict-of-interest concerns.
The analysis below was produced from the pre-decision document only — no hindsight. This is what the platform would have surfaced if it had been running in 1999-06-28.
“Enron board meeting minutes from June 1999 document the approval of CFO Andrew Fastow's role as managing partner of LJM Cayman L.P. — a special purpose entity that would transact with Enron. The board waived Enron's Code of Ethics specifically to permit Fastow's dual role. Minutes reflect no challenging questions about the inherent conflict of interest. Similar waivers were granted for LJM2 (October 1999) and Chewco.”

Red flags detectable at decision time
- Formal waiver of Enron's Code of Ethics to allow CFO to run a counterparty to Enron
- Board approval of LJM transactions without independent legal and financial review
- Arthur Andersen auditors received ~$25M in consulting fees annually — larger than audit fees
- Sherron Watkins' August 2001 memo to Ken Lay warning 'Enron could implode in a wave of accounting scandals' was not escalated to the board
- Mark-to-market accounting on Raptors hedged Enron stock — making hedges worthless when stock fell
Cognitive biases the platform would have flagged
Hypothetical analysis
DI would flag the Code of Ethics waiver as the canonical authority-bias + halo-effect decision. Skilling/Fastow's perceived brilliance caused the board to treat the fundamental conflict-of-interest as an administrative detail rather than a governance red flag. A bias-adjusted review would have required independent outside counsel plus a non-management board committee veto on any CFO-counterparty structure. Sherron Watkins' memo in August 2001 represents the canonical 'ignored dissenter' pattern — had any governance circuit-breaker been working, her warning alone would have paused operations.

Lessons learned
- Boards that defer to charismatic executives without independent scrutiny become rubber stamps for fraud.
- Confirmation bias in auditing relationships (Arthur Andersen) allowed accounting irregularities to persist for years.
- Whistleblower protections are essential; Sherron Watkins' warnings were ignored because the culture punished dissent.
