What is earnings quality — and how to spot fake profits

Why reported profit can lie

Net income is an accounting number, and accounting gives management real discretion: when to recognize revenue, how fast to depreciate, what to call “non-recurring,” how to value inventory. None of that is necessarily fraud — but it means two companies with identical cash economics can report very different profits. High earnings quality means the reported number closely tracks the cash the business actually generates. Low quality means it doesn't — and the difference tends to reverse, painfully, later.

The three checks that catch most of it

1. Does profit turn into cash?

Over time, net income and operating cash flow should rise together. If reported profit keeps climbing while operating cash flow stalls or falls, the “profit” is increasingly made of accruals — earnings booked now that may never become cash. A persistent, widening gap between the two is the single most reliable earnings-quality warning sign there is. (It was hiding in plain sight for years before Enron and Wirecard.)

2. Are receivables outrunning sales?

If revenue grows 15% but accounts receivable grow 40%, the company may be booking sales it hasn't collected — by loosening credit, stuffing the channel, or recognizing revenue aggressively. Receivables (and inventory) growing materially faster than sales is a classic prelude to a write-down or a restatement.

3. Are the “one-offs” actually recurring?

A “non-recurring” charge that shows up every single year isn't non-recurring — it's the cost of running the business, dressed up to flatter the adjusted number. Same with an ever-growing pile of add-backs between GAAP and non-GAAP. When the gap between what the company earns and what it asks you to look at keeps widening, be skeptical.

How the formal screens work

You don't have to eyeball this. Two screens formalize the checks above:

• The Beneish M-score combines eight ratios (days-sales-in-receivables, gross margin, asset quality, sales growth, accruals, and more) into one number that statistically flags companies likely to be manipulating earnings.
• Cash-conversion & accrual ratios (including the Sloan accrual ratio) measure directly how much of reported profit is showing up as cash versus paper.

Both are deterministic — fixed formulas from the filing data, reproducible, no opinion involved. They don't prove fraud; they tell you where to look harder.
