Accounting Quality for Stock Investors

1. Operating cash flow consistently below net income. When OCF trails net income for two or more consecutive years, earnings are running ahead of real cash — the Sloan accrual anomaly that historically resolves through earnings disappointments, not a cash rebound. WHERE TO FIND IT — Cash Flow Statement — compare "Net cash provided by operating activities" to net income on the Income Statement.
2. Recurring "non-recurring" charges. Restructuring, impairments, or litigation costs that appear every quarter are operating expenses management relabels as one-time items. Adjusted EPS overstates recurring profitability by exactly that amount. WHERE TO FIND IT — Earnings press release (8-K, Exhibit 99.1) — the GAAP-to-Non-GAAP reconciliation table; or the income statement footnotes in the 10-K.
3. Days Sales Outstanding rising faster than revenue. Expanding DSO means the company is booking sales before customers pay — the earliest reliable signal of aggressive revenue recognition, typically preceding a receivables write-down by 2–4 quarters. WHERE TO FIND IT — Balance sheet (Accounts receivable ÷ annualized revenue × 365), compared year-over-year in the 10-K; revenue recognition policy footnote.
4. GAAP-to-adjusted earnings gap above 20% for two or more years. A widening gap with the same excluded categories year after year signals that recurring operating costs are being hidden from the headline number investors capitalize. WHERE TO FIND IT — Earnings press release (8-K, Exhibit 99.1) — the "Reconciliation of GAAP to Non-GAAP Financial Measures" table near the end.
5. Rapid goodwill growth without revenue acceleration. Goodwill expands through acquisitions. When goodwill grows sharply but revenue does not accelerate in proportion, the company is likely overpaying and will eventually impair — reducing future book equity and flattering current asset returns. WHERE TO FIND IT — Balance sheet ("Goodwill and intangible assets"); the Business Combinations footnote in the 10-K.

1. STEP 1 — Earnings Quality Score — Do reported earnings convert to operating cash flow? The scorer computes the accrual ratio, GAAP-to-adjusted gap, AR growth vs. revenue, and cash conversion in one pass, returning a 0–100 score that flags the exact dimension that fails.
2. STEP 2 — Cash Conversion Cycle — How efficiently does the company collect receivables and manage payables? A lengthening cycle while revenue stays flat means working capital is absorbing more cash — often the mechanism behind a declining cash conversion ratio.
3. STEP 3 — ROA Calculator — Is the asset base generating adequate returns, or growing faster than profits? Rising net income alongside falling ROA is a dilution of asset quality — frequently the result of acquisitions booked at inflated goodwill.
4. STEP 4 — DSO Calculator — Is revenue being recognized at a pace matched by cash collections? Rising DSO is the earliest externally visible signal of aggressive revenue recognition and a near-universal precursor to future earnings restatements.

Accrual accounting recognizes revenue when it is earned, not when cash arrives. A company ships product in December, books the revenue, and may not collect the cash until February. The income statement says profitable quarter; the cash flow statement says cash is still outstanding. Over one quarter, this is normal. Over multiple years, it is a warning.

Three patterns create the largest gap between reported earnings and real economic value:

Timing mismatches: Revenue recognized before cash arrives inflates accounts receivable. Watch for AR growing faster than revenue — the Days Sales Outstanding metric captures this in a single number.

Capitalized costs: R&D, software development, and certain marketing expenses can be capitalized and depreciated over several years rather than expensed immediately. This smooths reported earnings but defers the real cost. Compare the income statement R&D line to the cash flow statement to see if a gap is growing.

The FCF confirmation signal: Free cash flow conversion — FCF divided by net income — cuts through all of it. A ratio consistently above 0.9 means earnings are well-backed by cash. Below 0.6 for two consecutive years is a structural warning, not a timing blip. Businesses that compound shareholder value over time almost always have FCF conversion above 1.0 at the peak of their quality.

A concrete example: A company reports $200M net income while generating $80M in operating cash flow. The $120M gap might reflect $60M in deferred revenue timing, $40M in capitalized development costs, and $20M in rising AR. Each is defensible in isolation. Together, they signal that $1 of reported earnings is backed by only $0.40 of real cash — below the threshold where earnings should be trusted at face value.

Income Statement

1. Gross margin compression while revenue grows. Rising revenue masking a shrinking margin means pricing pressure, rising input costs, or channel mix shift — all of which accelerate on a downturn.
2. Revenue growing faster than cash collections (AR days spiking). The earliest externally visible signal of aggressive revenue recognition; typically precedes a receivables write-down by 2-4 quarters.
3. Recurring non-recurring charges. Restructuring or impairment costs that appear every quarter are operating expenses relabeled — adjusted EPS overstates recurring profitability by exactly that amount.
4. Tax rate that falls every year despite stable or rising profits. One-time credits or deferred tax assets can reduce effective rates temporarily; a multi-year trend is worth tracing to the footnote.
5. GAAP-to-adjusted gap above 20% for two or more years. A widening gap with the same excluded categories year after year signals recurring costs are being hidden from the headline number investors capitalize.

Balance Sheet

1. Goodwill above 40-50% of total assets. Acquisition-dependent growth that can reverse through impairments; rising goodwill without proportional revenue acceleration means overpaying.
2. Accounts receivable growing faster than revenue. Either sales are being pulled forward or collection terms are being relaxed to hit growth targets — both resolve unfavorably.
3. Inventory accumulating faster than cost of goods sold. Rising inventory-to-COGS ratio means either demand is softening or product is becoming obsolete; both eventually require a write-down.
4. Net debt rising while FCF stays flat or falls. Leverage that is not funding growth is funding distributions or operations — unsustainable when rates rise.
5. Off-balance-sheet commitments growing. Operating lease commitments, purchase obligations, and contingent liabilities appear in footnotes, not the balance sheet; they represent real future cash outflows.

Cash Flow Statement

1. Operating cash flow persistently below net income. When OCF trails net income for two or more consecutive years, earnings are running ahead of real cash — the Sloan accrual anomaly historically resolves through earnings disappointments, not a cash rebound.
2. CapEx rising as a percentage of revenue without margin improvement. Capital intensity increasing without a return means growth requires more and more capital input — a compounding drag on future returns on equity.
3. High working capital builds classified as operating cash flow. Changes in working capital appear inside operating cash flow — a large positive quarter from releasing inventory or collecting AR flatters OCF without reflecting operating improvement.
4. Acquisitions substituting for organic growth in the investing section. A company that consistently shows negative organic FCF but funds distributions through asset sales or debt is not self-funding its business model.
5. Stock buybacks funded by debt, not free cash flow. Buybacks that reduce share count while net debt rises transfer wealth from creditors to shareholders rather than creating it — attractive EPS growth, declining financial health.
