Quality of Net Assets (QoNA) in FDD: test the balance sheet for under-provisioning, overstated assets and off-balance-sheet items that feed net debt and working capital.
Most candidates can talk fluently about earnings. Ask them how a buyer gets comfortable with the balance sheet they are inheriting, and the answer thins out fast. Yet when a deal goes wrong in the first year of ownership, it is rarely because EBITDA was misstated by a few points. It is because a provision was missing, an asset was carried at a value nobody could support, or a liability was sitting just off the page. That is the territory of Quality of Net Assets (QoNA) — the balance sheet cousin of the Quality of Earnings work that gets all the attention. Master it and you become the analyst the deal team trusts with the half of the accounts everyone else skims.
Quality of Net Assets is the diligence workstream that asks a deceptively simple question: are the net assets of the target stated at a value a reasonable buyer would accept? Where Quality of Earnings interrogates the P&L to arrive at a sustainable, normalised EBITDA, QoNA interrogates the balance sheet to arrive at a defensible view of what the business actually owns and owes at completion.
The two are joined at the hip. An accounting policy that flatters earnings — say, capitalising costs that should be expensed, or releasing a provision into income — almost always leaves a fingerprint on the balance sheet. QoNA is where you find it. A clean QoE that ignores the balance sheet is half a job.
Crucially, QoNA is not a re-audit. The auditors have signed the accounts and you are not repeating their opinion. You are asking a different question: not "is this GAAP-compliant?" but "would a rational buyer accept these carrying values, and if not, what does that do to the price?" Those are very different bars. A provision can be perfectly defensible under the accounting framework and still be one a buyer would insist on topping up before signing.
An auditor asks whether the numbers are fairly stated; a diligence analyst asks whether a buyer would pay for them. The gap between those two questions is where deal value is won and lost.
A buyer pays an enterprise value derived largely from earnings, then adjusts to equity value through the net debt and working capital mechanism. QoNA underpins both of those bridges. If the balance sheet contains overstated assets or understated liabilities, three things happen:
In short, QoE tells you what the business earns; QoNA tells you whether the platform it earns from is solid. The best FDD analysts see the two as a single system: an earnings adjustment with no balance sheet consequence is usually wrong, and a balance sheet finding that never reaches the equity bridge has been left half-finished.
Almost everything QoNA finds falls into one of three buckets. Memorise them, because they structure the entire review.
The most common — and most consequential — finding. The analyst tests whether provisions are adequate and complete:
Under-provisioning is attractive to a vendor preparing for sale precisely because it flatters both net assets and, in the year of release, earnings.
The mirror image. Here the analyst asks whether each asset can be supported at its carrying value: receivables (ageing, disputed balances, related-party debtors, amounts unlikely to convert to cash); inventory (net realisable value below cost); fixed assets and intangibles (impairment, fully-depreciated assets still in use, capitalised development costs or goodwill with no supporting cash flows); and prepayments (genuine future benefit, or a parking space for costs the business did not want in the P&L?).
The items that never touched the primary statements but transfer to the buyer all the same: operating commitments, supplier financing and reverse factoring, factored receivables with recourse, guarantees, contingent earn-outs, pension deficits, and unrecorded liabilities such as accrued bonuses or unbilled supplier costs. This is where the difference between reported net assets and economic reality most often hides.
A competent QoNA review works line by line down the balance sheet, and for each material caption asks three questions: what is the carrying value, what is the recoverable or settlement value, and what evidence supports the difference. The tools are unglamorous but powerful — ageing profiles, roll-forwards, provision-adequacy tests, and third-party confirmations.
Take receivables. You pull the aged debtor listing, look at how much sits beyond terms, compare the bad-debt provision to actual write-off history, and test whether the provisioning policy has kept pace with the ageing. If debtor days have crept up while the provision has stayed flat, you have found under-provisioning — and probably a revenue-quality issue too, since aggressive recognition often shows up as debtors that never convert to cash. This is where QoNA and revenue quality shake hands.
Provisions get the same treatment. For each one you want the opening balance, the charge, the utilisation and the release, and you test whether the closing figure is adequate. A provision that is repeatedly released into income is a classic earnings-flattering device: the charge boosted a prior period, the release boosts the current one, and the balance sheet quietly shrinks.
Numbers make this concrete. Suppose a target reports net assets of £42.0m. Your QoNA review turns up four issues, each supported by evidence in the data room. Here is how they roll through to an adjusted figure.
| Item | Finding | Adjustment (£m) |
|---|---|---|
| Reported net assets | Per completion balance sheet | 42.0 |
| Trade receivables | Aged >120 days, no realistic prospect of collection, un-provided | (1.8) |
| Warranty provision | Actual claim run-rate implies provision short by | (1.2) |
| Capitalised development | Project cancelled Q3, asset carries no future benefit | (0.9) |
| Dilapidations | Lease exit obligations never provided for | (0.6) |
| Adjusted net assets | 37.5 |
That is a £4.5m reduction — over 10% of reported value — none of it fraud and all of it legitimate diligence judgement. Note the discipline: every adjustment ties to a specific piece of evidence, not a hunch. A finding you cannot source in the data room is a finding you cannot defend in a negotiation.
This is the part interviewers love, because it shows you understand that diligence findings are not academic — they move the price. QoNA findings split into buckets, and the classification matters enormously.
| Finding | Treatment | Effect on the buyer |
|---|---|---|
| Debt-like item (unfunded pension, factoring with recourse, deferred consideration, dilapidations) | Added to net debt | Reduces equity value pound-for-pound at completion |
| Working-capital quality (under-provisioned debtors, obsolete stock, stretched payables) | Feeds the working capital normalisation and target | Adjusts the completion true-up |
| Pure earnings-quality (over-capitalisation, provision releases) | Flows into the QoE / EBITDA bridge | Affects the multiple-driven enterprise value |
The art is allocating each finding to the right bucket without double-counting. A pension deficit belongs in net debt — not also as a charge against normalised EBITDA. And because a pound treated as debt reduces the price directly at completion, whereas a pound treated as working capital only bites to the extent it moves the working capital target, sellers fight hard over which bucket an item lands in. A well-argued QoNA workstream gives your deal team the ammunition to hold the line.
Some findings recur across almost every deal, and knowing the usual suspects lets you head straight for them:
Notice how many of these overlap with the red flags an experienced analyst carries around in their head. QoNA is, in large part, the discipline of turning those instincts into evidenced, quantified adjustments a deal team can negotiate on.
Interviewers use QoNA to separate candidates who have only read about QoE from those who understand the whole balance sheet. A favourite arrives disguised as a balance sheet question: "The target's receivables provision has been flat at £200k for three years while revenue has doubled. What do you do?"
A strong answer sounds like this: "I'd be sceptical that a flat provision is appropriate against a doubling debtor book, so first I'd pull the ageing and historical write-off experience to test whether the provision is supportable. If it's understated, I have two questions: how much is the catch-up, and is it a one-off or a recurring policy issue? A one-off catch-up I'd treat as a debt-like adjustment reducing equity value at completion. If the under-provisioning has also been flattering EBITDA — because charges that should have hit the P&L never did — then I'd reflect that in the QoE too, being careful not to double-count between the earnings bridge and the net debt or working-capital adjustment. And I'd quantify every piece against specific evidence in the data room, because an unquantified observation is useless in a negotiation."*
That answer signals three things interviewers want: you read the balance sheet critically, you understand the net debt and working-capital mechanics, and you can translate a finding into a price impact without double-counting.
QoE will always get top billing, and rightly so — earnings drive the enterprise value. But the balance sheet is where the buyer's downside lives, and QoNA is how you protect against it. Learn to trace a provision from the ledger, through the roll-forward, into net debt, and out the other side as a pound off the price — and you will never again be the candidate whose answer thins out when the question moves below the EBITDA line. That fluency is exactly what turns a competent analyst into one the deal team cannot run a transaction without.
