Anonymised, illustrative composite. An Ontario general contractor, a standard net-working-capital closing mechanism, and a statutory retention that behaves nothing like the trade receivables and payables the peg was built to measure.
At a glance
The target was an Ontario general contractor doing $22 million a year in institutional and commercial renovation work, sold by share purchase. The purchase agreement used the standard mechanism for a deal this size: a net working capital peg, set from the average of the prior twelve months’ month-end balances, with a dollar-for-dollar purchase-price adjustment if the closing-date working capital landed above or below it. The peg’s definitions followed the buyer’s template — consistent accounting policies, GAAP current-asset and current-liability classifications — with no line dealing with construction holdback specifically.
Every contract the target performed as a general contractor, and every subcontract it awarded downstream, was subject to the same statutory retention regime. On the closing balance sheet, that regime touched both sides of the ledger at once: money owed to the target that it could not yet collect, and money the target owed that it was not legally permitted to pay yet either.
The target’s controller had always carried holdback amounts as ordinary trade receivables and payables, aged the same way as everything else on the balance sheet. The buyer’s diligence accountants, building the closing working capital calculation on that convention, initially did the same — and produced a working capital figure that looked comfortably above the peg, because $860,000 of receivables that were not actually collectible on demand were sitting in current assets at full face value, aged no differently from a customer invoice due in 30 days.
The receivable side: $860,000 of statutory holdback owed to the target across eleven active contracts, ranging from contracts still mid-performance to two that had reached substantial performance months earlier and were within their lien expiry window. The payable side: $410,000 of holdback the target itself owed its own subcontractors under the identical regime, running in the opposite direction. Reclassifying the receivable side out of ordinary current assets, and confirming the payable side as a fixed, non-accelerable liability rather than negotiable trade debt, moved the working capital calculation from a reported $250,000 surplus above the peg to a $610,000 shortfall below it — an $860,000 swing driven entirely by how one asset was classified.
Construction Act s.22(1) is the source of both sides of the problem: “Each payer upon a contract or subcontract under which a lien may arise shall retain a holdback equal to 10 per cent of the price of the services or materials as they are actually supplied under the contract or subcontract … until all liens that may be claimed against the holdback … have expired or been satisfied, discharged or otherwise provided for under this Act.” Read from the target’s side as payee, that retention is money owed to it that the payer is legally forbidden to release early — not a receivable an ordinary collections effort can accelerate, and not an asset free of competing claims, because it exists specifically to satisfy lien claims that may be asserted against it by subcontractors and suppliers below the target on the same project. Read from the target’s side as payer, on its own subcontracts, the identical obligation runs the other way: money it is legally required to keep withholding, on a timeline set by lien expiry rather than by ordinary payment terms.
s.22(2) layers a second, independent obligation on top: once a contract is “certified or declared to be substantially performed but services or materials remain to be supplied to complete the contract, the payer … shall retain, from the date certified or declared to be the date of substantial performance … a separate holdback equal to 10 per cent of the price of the remaining services or materials as they are actually supplied.” Two of the target’s larger contracts reached substantial performance during the diligence period, which meant a second 10% finishing holdback started accruing on the punch-list balance of those contracts, tracked apart from the original s.22(1) holdback on the work already completed — two separate retention pools on the same contract, with two separate release triggers.
Neither the target’s ordinary accounting convention nor the buyer’s template working capital definitions were built to see this. A net working capital peg is designed around ordinary trade receivables and payables that turn on a predictable cycle and carry no legal restriction on timing. Statutory holdback is neither: it is not collectible on demand as an asset, and it is not payable on demand as a liability — both sides are locked to lien expiry, a date set by statute and the project’s own performance milestones, not by the parties’ payment terms.
The purchase agreement was amended before closing to carve statutory holdback receivable out of the working capital peg entirely, tracked instead as a separate, non-current item collectible only as liens actually expired post-closing, with the buyer entitled to a further adjustment for any holdback that ultimately proved uncollectible against a competing lien claim. Holdback payable was confirmed as a fixed liability the buyer would assume and could not accelerate. The $610,000 shortfall, correctly calculated, produced a purchase-price reduction under the agreement’s existing dollar-for-dollar collar — the mechanism worked exactly as designed once it was measuring the right thing.
Had the closing statement gone out on the original convention, the buyer would have paid full price on the strength of an $860,000 asset that was, in substance, a series of contingent claims subordinate to competing lien rights on projects it did not control the completion of — and would have discovered the true collectibility of that receivable only months later, contract by contract, as liens expired or, in the worst case, did not because a downstream subcontractor was left unpaid and registered a claim against the same fund. The mismatch would have surfaced as a post-closing cash shortfall with no adjustment mechanism left to correct it, because the true-up window under most working capital collars closes within 90 to 120 days of closing — often before a longer lien period on a substantially performed contract has even run.
The tell is that the target’s own books never distinguished holdback from ordinary trade balances, because for a contractor operating inside the regime every day, holdback is simply how the business works — not a special case worth a separate account. A working capital peg built for a generic target and applied to a construction business without modification will silently import that same blind spot. Any purchase agreement for a contractor, subcontractor, or trade business performing lienable work needs the peg’s definitions to name statutory holdback specifically on both sides of the balance sheet, or the number the collar produces is measuring the wrong thing.
