High-quality earnings are repeatable, cash-backed, and free from aggressive accounting choices. Low-quality earnings rely on accruals, one-time gains, or estimate changes that flatter the income statement without generating cash.
| Signal | High Quality | Low Quality |
|---|---|---|
| CFO vs Net Income | CFO ≥ Net Income | CFO << Net Income |
| Accrual Ratio | Below 5% | Above 10% |
| Revenue sources | Recurring, cash-collected | One-time gains, unbilled |
| Estimate changes | Stable, conservative | Frequent, income-boosting |
Accrual Ratio (CF) = (Net Income − CFO − CFI) / Avg Total Assets
Going Deeper — cookie-jar reserves and the small-profits kink. Empirically, far more firms report tiny profits than tiny losses (the "kink" in the histogram around zero) — evidence that managers systematically nudge marginal results across the threshold. The mechanism is reserves: in good quarters, management over-reserves for warranty, litigation, or restructuring; in weak quarters, the reserve is partially released, and the income-statement effect flatters EPS. The reserve becomes a cookie jar that opens when needed. Probing question: "Has this company beat consensus by exactly a penny more than 75% of the time across the last 16 quarters? That alone is a flag."
Going Deeper — the four-question earnings-quality framework. Apply four tests to any reported earnings number before you multiply by anything. (1) How recurring? Strip out one-time gains, restructuring charges, litigation settlements, and discontinued-operations effects to isolate the run-rate. (2) How certain? Reserve adjustments, deferred-tax true-ups, and goodwill impairments are judgment-heavy; treat them as a narrower subset of the recurring number. (3) How cash-backed? Compute the cash conversion ratio (operating cash flow ÷ net income); a CCR well below 1 over multiple periods is a warning that accruals are doing the heavy lifting. (4) What multiple does the residual deserve? The recurring + certain + cash-backed slice deserves the peer multiple; everything else deserves substantially less. Worked example — Westmoor Optical Q3 reported $48M net income decomposed: $42M operating (recurring, $36M cash-backed), $4M deferred-tax adjustment (judgment heavy, will reverse), $2M settlement (one-time). Core recurring cash earnings $36M, vs the headline $48M. Applied at a 16x peer multiple the gap between disciplined and naive valuation is roughly $190M of equity value — about a third of any small-cap mispricing edge. AI prompt: "Walk through [TICKER]'s most recent quarterly earnings using the four-question framework. Quantify the recurring vs one-time split, the judgment-heavy vs transactional split, and the CCR. Return a decomposed core earnings number."
Sit with the ideas.
A company reports net income of $180M, but operating cash flow is only $95M. Total accruals to total assets (TATA) is 0.08, and the Days Sales in Receivables Index (DSRI) is 1.35. What does this combination suggest?
