Cash quality ratios

Two companies report the identical profit: ₹500 crore each. One collected ₹520 crore of cash from running its business over the year; the other collected ₹120 crore. Same profit on the P&L, a nearly ₹400 crore difference in the money that came in the door. The first firm's profit is backed by cash. The second firm's profit is, for now, a promise - parked in receivables that may or may not pay, in inventory that may or may not sell, in entries the cash has not yet confirmed. illustrative

An earlier module put it plainly: profit is an opinion, cash is a fact. Reported profit is assembled under rules that allow - and sometimes require - a great deal of judgement: when to recognise revenue, how fast to depreciate, what to provide for. Most of the time that judgement is honest. But it leaves room for profit the cash has not backed, whether through aggressive choices, optimistic assumptions, or simply a business whose cash is trapped in working capital. Cash-quality ratios exist to catch that gap, because cash is far harder to fake than profit - you can book a sale, but you cannot book the money arriving in the bank. They do not ask "how much profit did the company report?" They ask "how much of that profit turned into cash, and if it did not, why not?" This module is about three of those checks - operating cash flow against profit, free cash flow conversion, and the cash tax rate against the P&L tax charge - read as a lie-detector wired to the bottom line.

CFO to PAT: does the profit become cash? Take operating cash flow from the cash flow statement and divide it by net profit. Read it over three to five years, never one - any single year is noisy from a working-capital swing, a one-off receipt, a timing difference. Across several years the ratio should sit around one or above. Consistently above one is normal and healthy for a business with heavy depreciation, whose cash flow exceeds its profit by the non-cash charges added back. Consistently below one is the warning: profit is being reported that operations are not turning into cash, and you must find where it is going - into a genuine working-capital build for growth (benign), or into receivables that are not collecting and inventory that is not selling (not benign).

Free cash flow conversion: how much cash is truly spendable? Operating cash flow flatters a capital-hungry business, because it is measured before the capital spending the business needs to survive. Free cash flow - operating cash flow minus capital expenditure - is the cash left after the business has fed itself, and it is what actually funds dividends, buybacks and debt repayment. Free cash flow, not reported profit, is the cash an owner could take out without starving the business - which is why it, and not the P&L line, is the honest measure of what the profit produced. But split the capex first: maintenance capex keeps the existing business running, while growth capex builds new capacity. Take a firm with ₹400 crore of operating cash flow and ₹600 crore of capex, so free cash flow is minus ₹200 crore. If ₹150 crore of that capex merely maintains the existing plant and ₹450 crore builds a new line, the ongoing business actually threw off ₹250 crore of free cash and chose to spend it, plus more, on expansion - that is investment. Flip the split - ₹450 crore of maintenance, ₹150 crore of growth - and the same minus ₹200 crore means the business cannot even keep its existing assets running out of its own cash, which is trouble. The headline free cash flow is identical; the split decides the verdict, and the notes and capex commentary are where you find it. illustrative

Cash tax versus book tax: is profit outrunning taxable profit? In the cash flow statement, find the tax actually paid in cash and compare it with the tax charged in the P&L. A gap in a single year is usually timing - accelerated depreciation for tax, a one-off allowance. But a persistent, widening gap, where the book charge stays high and the cash paid stays low, means book profit is consistently exceeding the profit declared to the tax authority, with the difference piling up as deferred tax on the balance sheet. Tax is paid in cash on real taxable profit, so this is one of the least-watched and most useful earnings-quality checks there is: a quiet signal that the reported earnings may be more aggressive than the cash-based, taxable reality.

What counts as healthy cash conversion depends on the shape of the business - how asset-heavy it is, how it carries working capital, whether it is a lender at all. The same CFO-to-PAT reading is a clean bill of health in one business and an alarm in another, so the ratio has to be judged against the sector's natural cash shape before it can tell you anything.

For an asset-light firm, profit and cash should move together, so a gap is alarming precisely because nothing structural explains it. For a capital-heavy manufacturer, operating cash flow naturally exceeds profit while free cash flow can be negative through an investment cycle - so you read CFO-to-PAT for quality and treat negative FCF as a question about whether the capex is growth or upkeep, not an automatic failure. For a working-capital-heavy business, cash lagging profit is normal, and the real question is the reason, which the efficiency-ratio trends answer. And for a lender, the whole CFO-to-PAT frame does not apply; earnings quality lives in provisioning and asset quality instead. The same gap between profit and cash is benign in one business and damning in another - you cannot read it until you know which shape you are holding.

A composite branded-goods company reports five straight years of rising profit, and the market treats it as a steady compounder. Run the cash-quality checks across those five years before you agree. illustrative

Start with CFO to PAT: 0.9, 0.8, 0.7, 0.6, 0.5. No single year looks alarming; as a trend it is damning. Each year a larger share of reported profit fails to become operating cash - the ratio is not just below one, it is sliding steadily further below. So the "rising profit" is increasingly a paper figure. Where is the cash going? Cross to the working-capital trend and the answer appears: receivables have grown much faster than sales for four straight years, and inventory is building too. The profit is being booked on sales that are not collecting and stock that is not selling. Now the tax cross-check: the P&L has charged around 25% throughout, but cash tax paid has fallen to single digits as a share of pre-tax profit, and deferred tax on the balance sheet is swelling - a second, independent signal that book profit is running ahead of the real, taxable profit.

Two separate cash-quality checks - the falling CFO-to-PAT and the widening book-versus-cash tax gap - point at the same conclusion from different directions: the reported profit is drifting away from the cash. The "steady compounder" is compounding its earnings faster than its cash, which is exactly the pattern that precedes a receivables write-down or a nasty reset once the working capital finally has to be cleaned up. None of it shows on the profit line, which marches up cleanly all five years; all of it appears the moment you hold that profit against the cash. The habit to build is to run CFO-to-PAT as a multi-year trend and the cash tax rate as a cross-check before you believe any profit story.

These checks are powerful, but they are trend instruments with two hard limits, and the same two limits are where most readers get fooled.

They convict on the pattern, never on one year. A single year's gap is noise; the multi-year direction is the signal. A genuine working-capital build for real growth, a one-off tax payment, a large customer paying just after year-end - any of these can push CFO-to-PAT below one for perfectly innocent reasons that reverse. A single year raises a question; only a persistent, multi-year pattern turns the question into a finding. Reading one bad year as proof of manipulation is as much an error as ignoring a five-year slide - and the mirror trap, reading CFO-to-PAT on a single year, is the most common way the check gets misused.

They show that cash lagged, never why. A low CFO-to-PAT is consistent with an honest, fast-growing firm funding its own working capital and with a dishonest one booking uncollectable sales - the ratio looks identical in both. The distinction lives in the reason: the quality of the receivables, the reality of the growth, the ageing of the working capital. So too with free cash flow, which cannot on its own separate growth capex from maintenance - the difference between an investment and a problem. Companies rarely split their capex cleanly, so a deeply negative free cash flow can be a firm building its future or one unable to fund its own upkeep, and the headline number does not say which. Estimating the split - from the capex commentary, the capacity announcements, and depreciation as a rough floor for maintenance - is a judgement the ratio requires but cannot make for you. The ratio points the torch; you still have to walk into the notes to see what it is shining on.

How it comes up. When profit rises but cash does not follow, a sharp analyst asks management to reconcile the two: "Profit grew 20% but operating cash flow was roughly flat, and CFO-to-PAT has now fallen three years running. Can you walk us through where the cash went, and why cash tax paid is so far below the P&L charge?" The analyst is holding the profit against the cash and asking for the bridge.

A good answer, verbatim-style.

"Fair challenge. The cash gap is almost entirely a working-capital build - we extended terms to win a large new distributor, which added about 25 days of receivables this year, and we're carrying more inventory ahead of the new launch. Both are deliberate and we expect the ratio to recover to around 1x next year as it stabilises. On tax, the gap is accelerated depreciation on the new plant, which reverses over time; here's the deferred-tax bridge."

That names where the cash went, ties it to specific decisions, quantifies it, and explains the tax gap with a concrete, reversing cause.

An evasive answer, verbatim-style.

"Cash flow can be lumpy quarter to quarter and we manage the business for long-term profit growth, which remains excellent. Working capital is well controlled and we're very comfortable with the quality of our earnings and our receivables."

Notice the moves. "Lumpy" explains a single quarter, not a three-year slide; "we manage for profit growth" sidesteps the cash question entirely; and "comfortable with the quality of our earnings" asserts exactly what the numbers are calling into doubt, with no bridge and no figures.

The follow-up nobody asks. "Give us the five-year CFO-to-PAT, the split of this year's capex into maintenance and growth, and the deferred-tax movement behind the cash-versus-book tax gap." That forces the profit-to-cash relationship onto hard multi-year numbers and separates investment from leakage. If the room lets "cash can be lumpy, earnings quality is excellent" stand without the five-year conversion and the tax bridge, either the conversion trend is ugly or the deferred tax is building for a reason management would rather not detail. Profit that management will not reconcile to cash is profit worth reconciling yourself.
