Key Metrics & Shenanigans

Numbers that look real but aren't

Every number on a financial statement is the product of a choice. How do you recognize revenue? When does an expense become a capitalized asset? What depreciation schedule do you use? These choices are legitimately flexible within GAAP — and they're also exactly the places where management can distort reported results without technically breaking the rules.

Howard Schilit has spent four decades catalogueing these distortions. Financial Shenanigans (3rd ed., 2010) is organized around seven earnings-manipulation shenanigans plus an eighth category for cash-flow shenanigans. This lesson walks through each with the historical case studies that made them famous.

Schilit's framing:

If you focus on how a company makes its money and on the quality of that money, you can spot most shenanigans before they become front-page news.

Shenanigan #1 — Recording revenue too soon

What it looks like: booking revenue before the earnings process is complete. Sending product to distributors ("channel stuffing"), booking long-term contracts upfront instead of over time, recognizing revenue on sales with generous return rights, bill-and-hold arrangements.

Case study: Sunbeam (1996–1998). Al Dunlap — "Chainsaw Al" — used a bill-and-hold scheme to book millions in Q4 1997 sales that were actually backyard-grill inventory sitting in warehouses for future quarters. When the SEC investigated, Dunlap was banned from serving as an officer of a public company. Schilit dedicates a chapter to Sunbeam as the canonical modern example.

Where it shows up in ratios: DSO (days sales outstanding) balloons because "revenue" hasn't actually produced cash. Inventory falls relative to revenue because you've shipped product prematurely. Watch the ratio of accounts receivable to revenue over time.

Shenanigan #2 — Recording bogus revenue

What it looks like: revenue from transactions that are not real sales. Barter deals (swapping capacity with another company, both booking the swap as revenue); related-party transactions at inflated prices; round-tripping (selling to a third party who re-sells back to you).

Case study: Enron (1999–2001). Schilit documents how Enron's "special purpose entities" (SPEs) let it book revenue on sales to entities it controlled, inflating 2000 reported revenue from approximately $40 billion to $101 billion — a 2.5× inflation from accounting manipulation alone. When analysts could not reconcile the revenue figures with operating cash flow, the unwind was catastrophic. Enron declared bankruptcy in December 2001, erasing $74 billion of shareholder value.

Warning sign: divergence between net income growth and operating cash flow growth. Enron's reported earnings soared while cash from operations stagnated. Always cross-check earnings against operating cash flow.

Shenanigan #3 — Boosting income with one-time gains

What it looks like: selling assets for a gain and burying the gain in operating income rather than breaking it out as "other income." Re-classifying investment gains as revenue. Pension-accounting tricks that lower reported expense when equity markets rise.

Case study: General Electric (2000s). GE used its finance arm, GE Capital, to generate paper earnings through asset sales and securitizations that were reported alongside industrial operating income — obscuring the volatility and leverage of the financial business from investors analyzing "GE" as a unified company. The 2008 crisis revealed the degree to which GE's earnings quality depended on GE Capital, forcing a restructuring and ultimately the breakup of the conglomerate.

Warning sign: large and volatile "Other income" lines, or recurring "one-time gains" that are, in fact, recurring.

Shenanigan #4 — Shifting current expenses to a later period

What it looks like: capitalizing costs that should be expensed immediately — creating an asset on the balance sheet so the expense doesn't hit the income statement. Deferring costs. Lengthening depreciation periods.

Case study: WorldCom (1999–2002). WorldCom's CFO Scott Sullivan directed that approximately $3.8 billion in line costs — ordinary operating expenses paid to other carriers for call-termination — be capitalized as long-term assets rather than expensed. This single maneuver converted four consecutive quarterly losses into reported profits. When the internal auditor discovered the entries, the $3.8 billion figure grew to roughly $11 billion total in restatements. WorldCom declared bankruptcy in 2002, the largest corporate bankruptcy in U.S. history at that time; Sullivan served five years in prison and Bernard Ebbers (CEO) twenty-five years.

Warning sign: capital expenditures growing substantially faster than revenue. A sudden lengthening of asset-useful-life assumptions. Capitalized software development costs growing rapidly relative to R&D spend.

Shenanigan #5 — Employing other techniques to hide expenses or losses

What it looks like: keeping losses off the balance sheet through off-balance-sheet entities, understating pension expenses, releasing reserves into income, using restructuring charges to create "cookie jar reserves" that smooth future earnings.

Case study: Tyco International (1992–2002). Under CEO Dennis Kozlowski, Tyco made over 700 acquisitions in a decade. Each acquisition allowed Tyco to front-load acquired-company expenses as "restructuring charges" (reducing the acquirer's future expense base artificially), then slowly release reserves to boost subsequent-quarter earnings. Combined with personal enrichment through unapproved bonuses (famously the $6,000 shower curtain), Kozlowski was convicted of grand larceny in 2005 and served 8 years.

Warning sign: frequent large restructuring charges that later "release." Serial acquirers with erratic post-acquisition earnings patterns.

Shenanigan #6 — Shifting current income to a later period

What it looks like: the inverse of #1. If a company is beating estimates this quarter and worried about future quarters, delay some revenue into next period. Create reserves from today's good quarter to release later.

Case study: Freddie Mac (2001–2003). Freddie Mac misreported earnings by approximately $5 billion downward over three years in order to smooth reported results — keeping quarter-over-quarter earnings growth steady in a way that would have looked lumpier in reality. This sounds paradoxical ("they hid that they made too much money?"), but smooth earnings get higher valuation multiples; lumpy earnings don't. The SEC fined Freddie Mac $125M; the CEO and CFO both resigned.

Warning sign: unusually smooth quarterly earnings progressions — real business results are rarely that smooth.

Shenanigan #7 — Shifting future expenses to an earlier period

What it looks like: the reverse of #4. Instead of hiding current expenses, accelerate future expenses into the current period. "Big bath" accounting — when a company has already missed estimates, pile on every possible write-down so future quarters look artificially strong by comparison. Large impairments. Accelerated inventory write-offs.

Case study: HealthSouth (1996–2003). HealthSouth, under Richard Scrushy, fabricated $2.7 billion of earnings over seven years through a combination of #1, #2, and #7 — taking large "restructuring charges" that would later release as income. Fifteen senior executives pleaded guilty; Scrushy himself was acquitted of the financial fraud charges but later convicted of bribery of the governor of Alabama.

Warning sign: large write-downs concentrated in a bad quarter. Impairments that precede surprise earnings growth in subsequent quarters.

The cash-flow shenanigans

Beyond the seven earnings shenanigans, Schilit added a category in later editions for cash-flow manipulation — because as investors learned to cross-check earnings against cash flow, managements learned to manipulate cash flow too.

Fannie Mae (1998–2004). Classified roughly $6 billion of mortgage-related losses as if they were derivatives hedging rather than operating losses — keeping them out of operating cash flow. The distinction materially affected reported free cash flow used by rating agencies. Ultimately resulted in a $400M SEC penalty and CEO Franklin Raines's termination.

Core cash-flow tricks to know:

• Selling receivables to boost near-term cash (but losing discount on face value)
• Stretching payables timing — paying suppliers late to show more cash on the last day of a reporting period
• Classifying financing cash flow as operating (the Enron SPE trick applied to cash flow)
• Misclassifying interest payments as financing rather than operating

Ratio screens that catch most of this

Schilit and Perler recommend seven quantitative screens as an initial filter:

1. CFO (cash from operations) as a % of net income — should be > 100% consistently for mature businesses. Sustained < 80% is a red flag.
2. DSO (days sales outstanding) — rising DSO = shaky revenue quality
3. DPO (days payable outstanding) — rising DPO = potentially stretching payables to fake cash
4. Inventory days — rising = unsold product that revenue implied got sold
5. Accruals ratio — (Net income − CFO) / Total assets. High and rising = earnings outrunning cash.
6. "Soft" revenue growth vs hard revenue growth — real cash collected vs revenue booked
7. Reserves / provisions — sudden drops into income = cookie-jar accounting

Run these on every company before you buy. The historical cases above — Enron, WorldCom, HealthSouth, Fannie Mae — every one of them flunked multiple ratio screens for multiple quarters before the fraud broke. The information was publicly available. Most investors didn't look.

Quick check

What you now know

• Schilit's 7 shenanigans: record too soon (Sunbeam) • bogus revenue (Enron) • one-time gains (GE) • shift expenses later (WorldCom) • hide expenses via reserves (Tyco) • shift income later (Freddie Mac) • accelerate future expenses (HealthSouth)
• Cash flow shenanigans (Fannie Mae) exist because investors learned to cross-check earnings against cash
• The single strongest warning sign is CFO (cash from operations) diverging from net income for multiple quarters
• Capex/revenue ratio would have caught WorldCom; DSO and inventory days would have caught Sunbeam; related-party disclosures would have caught Enron
• Every major fraud in this lesson was publicly detectable in the financial statements — the math flunked before the auditors did
