1. Fabricating revenue outright
How it works: The company books sales that never happened, often by routing money through related or shell entities to create the paper trail of real transactions.
Case: Luckin Coffee (2019–2020). The SEC found the Nasdaq-listed Chinese coffee chain intentionally fabricated more than $300 million in retail sales through related-party purchasing schemes, inflating reported revenue by roughly 28% and 45% in successive 2019 quarters and inflating expenses by over $190 million to hide it. Luckin raised over $860 million from investors before the fraud surfaced, was delisted, and paid a $180 million SEC penalty. (SEC Press Release 2020-319; SEC Litigation Release 24987, Dec. 16, 2020.)

Hallmark: Revenue and profits that climb while operating cash flow lags, and sales concentrated in opaque related parties.
2. Recognizing revenue too early
How it works: Revenue that belongs in future periods is pulled forward — recognizing a multi-year contract up front, or booking "bill-and-hold" sales before goods ship or the customer is obligated.
Case: Xerox (1997–2000). The SEC charged that Xerox used undisclosed accounting actions to accelerate more than $3 billion of equipment-lease revenue and inflate pre-tax earnings by about $1.5 billion, recognizing lease revenue up front to close the gap between real results and Wall Street expectations. Xerox restated four years of results and paid a then-record $10 million penalty; its auditor, KPMG, was also charged. (SEC Press Release 2002-52; SEC Litigation Release 17465, Apr. 11, 2002.)
Hallmark: Growing unbilled or long-term receivables, and revenue-recognition policies that change or stretch the timing of sales.
3. Channel stuffing
How it works: The company floods distributors or wholesalers with more product than they can sell, booking the shipments as current-period sales to hit targets — borrowing from future demand.
Case: Bristol-Myers Squibb (2000–2001). The SEC found BMS ran a fraudulent earnings-management scheme, selling excess pharmaceuticals to its two largest wholesalers ahead of demand and improperly recognizing about $1.5 billion of revenue from those sales (while guaranteeing the wholesalers a return), and dipping into "cookie jar" reserves to meet estimates. BMS paid $150 million to the SEC and $300 million to settle related class litigation. (SEC Press Release 2004-105; SEC Litigation Release 18822, Aug. 4, 2004.)
Hallmark: Inventory piling up at distributors, quarter-end sales spikes, and rising days-sales-outstanding.
4. Capitalizing ordinary operating expenses
How it works: Routine costs that should hit the income statement immediately are instead recorded as long-lived assets, which understates expenses and inflates both profit and reported assets.
Case: WorldCom (1999–2002). WorldCom classified billions of dollars of ordinary "line cost" operating expenses as capital assets — about $3.8 billion in the initial disclosure, growing to roughly $11 billion of overstated results — turning real losses into reported profits. It became the largest U.S. bankruptcy at the time; CEO Bernard Ebbers was sentenced to 25 years, and the company paid a $750 million SEC penalty. (SEC v. WorldCom, Inc., S.D.N.Y. 2002.)
Hallmark: Capital-expenditure and asset lines rising faster than the business, with thinning cash flow behind the reported profit.
5. Hiding debt and losses off the balance sheet
How it works: Liabilities and money-losing assets are parked in special-purpose entities or partnerships the company controls but does not consolidate, so its own balance sheet looks far less leveraged than it is.
Case: Enron (through 2001). Enron used a web of special-purpose entities — the LJM partnerships, Chewco, and the "Raptors," orchestrated by CFO Andrew Fastow — to keep billions in debt and losses off its books, while using mark-to-market accounting to record projected future profits immediately. A late-2001 restatement pulled the hidden debt onto the balance sheet and erased years of earnings; Enron filed the largest U.S. bankruptcy then on record, its auditor Arthur Andersen collapsed, and executives were convicted. (Powers Report, Feb. 2002; SEC v. Fastow, 2002.)
Hallmark: Dense related-party and unconsolidated-entity footnotes, and profits that never convert into cash.
6. Disguising borrowings as sales to window-dress leverage
How it works: Near a reporting date the company "sells" assets under an agreement to buy them back days later, recording the financing as a sale so that debt temporarily disappears from the period-end balance sheet.
Case: Lehman Brothers (2007–2008). The court-appointed bankruptcy examiner found Lehman used "Repo 105" transactions to move roughly $50 billion of assets off its balance sheet at quarter-ends, temporarily lowering reported leverage to look healthier than it was, with no substance beyond that appearance. The examiner identified "colorable claims" of balance-sheet manipulation. (Report of Anton R. Valukas, Examiner, In re Lehman Brothers Holdings Inc., Mar. 11, 2010.)
Hallmark: Leverage that dips suspiciously at every quarter-end and rebounds afterward; heavy period-end repo activity.
7. Stretching depreciation and asset values
How it works: Extending the assumed useful lives of assets, inflating their salvage values, or delaying write-downs reduces the expense recognized each period and smooths or inflates reported earnings.
Case: Waste Management (1992–1997). Senior executives avoided depreciation expense by extending the useful lives and inflating the salvage values of garbage trucks and containers, failed to write down impaired assets, and used inflated reserves to absorb unrelated costs. The 1998 restatement of about $1.7 billion in pre-tax earnings was the largest in U.S. history at the time; the SEC sued six executives, and auditor Arthur Andersen paid a $7 million penalty. (SEC Press Release 2002-44; SEC Litigation Release 19351.)
Hallmark: Depreciation shrinking as a share of assets, lengthening asset-life assumptions, and few or no write-downs in a capital-heavy business.
8. Cookie-jar reserves and earnings smoothing
How it works: In good periods the company over-accrues reserves or takes an outsized charge, then quietly releases those reserves into income later to manufacture steady growth or a turnaround.
Case: Sunbeam (1996–1998). Under CEO Albert "Chainsaw Al" Dunlap, Sunbeam created excess restructuring reserves at the end of 1996 — deepening that year's loss — then released them into 1997 income to fake a rapid turnaround, alongside bill-and-hold and channel-stuffing sales. The SEC found at least $60 million of Sunbeam's reported $189 million in 1997 income came from fraud; Dunlap paid a $500,000 penalty and accepted a lifetime officer-and-director bar. (SEC Litigation Release 17001, 2001; settlement Litigation Release 17710, 2002.)
Hallmark: Unusually large restructuring charges followed by conveniently smooth earnings, and reserves that swing to hit targets.
9. Overstating assets — phantom cash, inventory, and receivables
How it works: The balance sheet is padded with assets that are overstated or simply do not exist — most damningly, cash 'held' in accounts that cannot be verified.
Case: Wirecard (through 2020). The German payments company reported €1.9 billion of cash supposedly held in escrow at two Philippine banks; auditors could not confirm it, the banks denied any relationship, and the company admitted the cash likely never existed. Much of its Asian revenue had been invented through third-party round-tripping. The DAX-30 firm collapsed into insolvency within days and its CEO was arrested. (Munich Public Prosecutor's Office, 2020; Wirecard ad-hoc disclosure, June 2020.)
Hallmark: Large cash balances a company somehow cannot deploy, auditor difficulty confirming assets, and delayed or qualified audits.
10. Misleading "adjusted" (non-GAAP) metrics
How it works: The company steers investors to a homemade profit metric that strips out real, recurring costs, making a loss-making business look profitable — often technically disclosed, but misleading in emphasis.
Case: Groupon (2011). Ahead of its IPO, Groupon headlined a metric it called Adjusted Consolidated Segment Operating Income ("ACSOI") that excluded its enormous online-marketing and subscriber-acquisition costs — turning a 2010 operating loss of roughly $420 million into a positive figure of about $60 million. SEC staff challenged the presentation under Regulation G and Item 10(e) of Regulation S-K; Groupon dropped the metric and later restated results, with its auditor flagging a material weakness. (SEC Corporation Finance comment letters, 2011; Groupon Form 8-K/A, 2012.)
Hallmark: A prominent "adjusted" metric that excludes recurring operating costs, presented more prominently than GAAP results.
Cross-cutting warning signs
These schemes differ in mechanics but share tells. Watch for:
- Profit that outruns cash: net income rising while operating cash flow stalls or falls.
- Working-capital drift: receivables or inventory growing faster than sales.
- Estimate-dependent earnings: results that hinge on reserves, useful-life assumptions, or fair-value marks management controls.
- Related-party complexity: revenue or financing routed through entities the company controls or is close to.
- Metric substitution: heavy reliance on non-GAAP figures and gross-billings framing over GAAP revenue and earnings.
- Governance signals: serial auditor changes, repeated restatements, material-weakness disclosures, late filings, and serial CFO turnover.
