Forensics 101: red flags hiding in the numbers

Everything in this module has been building toward this chapter. You can read the three statements; you can turn them into ratios; you know what a good business looks like. Now we turn the same tools the other way round — not to admire a business, but to catch one lying. This is the discipline auditors call forensic accounting, and the encouraging truth is that you don't need their qualifications to use most of it. Almost every accounting blow-up in Indian markets left its fingerprints in plain sight, in the published numbers, for anyone who read the statements against each other.

That last phrase is the whole secret: against each other. A single statement can be massaged. What's far harder to fake is consistency between the statements — between profit and cash, between sales and the assets that should accompany them, between what management says and what the numbers show. Fraud and aggressive accounting create contradictions, and the forensic mindset is simply the habit of hunting for them. Be clear about the spirit, though: most red flags are questions, not convictions. The job is to notice the contradiction and demand an explanation, not to cry fraud at the first odd number.

Red flag one: profit that never becomes cash

This is the king of all red flags, the one that has exposed more frauds than every other combined, and you already met it in the cash-flow chapter. A company reports years of healthy, rising net profit — but its cumulative operating cash flow lags far behind cumulative net profit. The profit is being booked on the income statement but never arriving in the bank.

Where does the missing cash 'go'? It piles up as assets that may not be real: swelling receivables (sales booked to customers who haven't paid and maybe never will) and bloating inventory (stock that isn't selling). Each year the gap is plugged by booking more uncollected sales, and the unpaid bills accumulate on the balance sheet like sediment. The income statement looks magnificent right up until the company can't pay its own bills and the whole edifice collapses in a single quarter.

Red flag two: receivables and inventory outrunning sales

The companion to the cash gap, and the mechanism behind it. In a healthy business, receivables and inventory grow roughly in line with revenue — sell more, and naturally carry proportionally more stock and unpaid invoices. The warning sign is when they grow much faster than sales.

• Receivables rising far faster than revenue — the company is booking sales it isn't collecting. Maybe it's selling to weak customers to chase growth; maybe it's stuffing the channel with goods distributors can't move; maybe it's recognising revenue too early. Often it's a sign the 'sales' aren't real economic transactions at all.
• Inventory rising far faster than sales — stock is piling up faster than it shifts. Either demand is falling and management won't admit it, or the inventory is becoming obsolete and a write-off is being deferred to a future year to protect today's profit.

Watch the days versions of these, from the working-capital chapter — days-receivable and days-inventory creeping up year after year. A lengthening cash conversion cycle with no convincing operational reason is the slow-motion version of this red flag, and it usually appears a year or two before the profit finally breaks.

Red flag three: the suspiciously smooth line

Counterintuitively, too much smoothness is itself a warning. Real businesses are lumpy — a bad monsoon, a lost contract, a commodity spike, a slow quarter all leave dents. A company that reports profit rising in an almost perfectly straight line, quarter after quarter, year after year, through good times and bad, while every competitor in the same industry visibly wobbles, is doing something its peers aren't. Sometimes that something is a genuine moat. Often it's earnings management — the quiet practice of stashing profit in good quarters and releasing it in bad ones to manufacture a comforting, unnatural smoothness.

Red flag four: where the cash actually went

Sometimes the trouble isn't fake profit but real cash leaving through the wrong door. This is where the forensic reader turns to related-party transactions and the financing pattern, both of which you met earlier — now read as fraud signatures rather than footnotes.

Red flag five: the people and the paperwork

The numbers don't move themselves — people move them — so the governance signals around the accounts are forensic evidence in their own right. An abrupt auditor resignation mid-term, especially with vague reasons, is among the loudest warnings in all of investing: auditors are paid by the company and rarely want a public fight, so when one walks, the disagreement underneath is usually serious. SEBI requires the reasons be disclosed — read them. The same goes for the sudden exit of a CFO, the person who knows exactly where the bodies are.

• Frequent changes of auditor or CFO, particularly clustered together or just before results.
• A qualified audit opinion, adverse opinion, or disclaimer — the auditor formally stating they're not comfortable.
• Accounting-policy changes that conveniently lift profit — a switch in depreciation method or revenue recognition timed to rescue a weak year.
• Complex, opaque group structures — webs of subsidiaries and joint ventures that make the consolidated picture impossible to follow, which is sometimes the point.
• An audit fee dwarfed by 'consulting' fees paid to the same firm — a conflict that can dull the auditor's scepticism.

The deepest point is one of attitude. The market rewards optimism most of the time, which trains investors to look for reasons to believe. Forensic reading is the deliberate opposite reflex: assume the story might be false and go looking for the contradiction that would prove it. You will be wrong often — many flagged companies turn out fine — but the cost of that is a missed opportunity, while the cost of ignoring a real red flag is a permanent loss of capital. In investing those two errors are not equal, and the forensic habit is how you keep the fatal one rare.
