1. The Operating Cash Flow to Net Income Spread
The single most reliable indicator of financial statement manipulation is an expanding divergence between reported GAAP net income and operating cash flow on the Statement of Cash Flows. When net income increases while operating cash flow turns negative or stagnates, the earnings are driven by non-cash accruals rather than customer payments.
2. Schedule II: Valuation and Qualifying Accounts
Tucked away at the very end of Form 10-K (Item 15 or Item 8), Schedule II details additions and deductions to allowances for doubtful accounts, sales returns, and inventory reserves. A declining allowance percentage during a period of expanding receivables is a classic sign of artificial profit support.
3. Note on Related Party Transactions
Under SEC Regulation S-K Item 404 and ASC 850, issuers must disclose material transactions with corporate insiders. Red flags include contracts with private entities controlled by executives' family members, unusual collateral guarantees, or asset transfers executed at period end.
