Anonymised, illustrative composite. Diligence never found a single reason to walk from the deal — it found something quieter: nobody but the owner had ever closed the shop's three biggest accounts, and the buyer's lender noticed before the buyer did.
At a glance
A buyer's letter of intent valued a specialty-services business at $2,400,000, priced against seller's discretionary earnings the buyer's diligence team had independently verified. The founder had built the business over eighteen years and remained its single point of contact for the three clients that produced roughly 60% of revenue — relationships that, on paper and in every reference call, ran through the founder personally.
Nothing in diligence raised a red flag in the ordinary sense. Financials reconciled, contracts were in good standing, there was no litigation. The one pattern the buyer's operating partner kept coming back to was smaller: the founder's own calendar, reviewed as part of transition planning, showed no vacation longer than three consecutive days across the entire period the corporate records covered.
The buyer's lender priced the acquisition loan using its own coverage discipline. Deavo's published acquisition-financing model puts that floor at “the 1.25× lenders look for,” carrying deavo's own disclaimer that it is an “illustrative estimate only — not a financing offer, pre-approval, or financial, legal or investment advice.” No statute sets a debt-service coverage floor; it is credit policy, which is exactly why it is negotiable in structure and not in principle. Run against a business whose earnings the underwriting model treated as carrying real key-person risk, full senior financing of the $2,400,000 price did not clear that coverage comfortably enough for the lender's committee to approve it without a transition safeguard.
The lender's ask was not a lower price. It was a structure: some portion of the purchase price deferred, contingent on the transition actually working, rather than paid in full at a closing where the founder's departure risk sat entirely with the buyer and the lender.
The parties structured $600,000 of the $2,400,000 price — 25% — as a vendor take-back note, with nothing paid on that portion at closing and principal due in three equal annual instalments of $200,000 beginning twelve months out. For the seller, that deferral is exactly the situation Income Tax Act s.40(1)(a)(iii) addresses: a reserve for the portion of the capital gain attributable to proceeds not yet received, capped at the lesser of a reasonable amount and the formula in clause 40(1)(a)(iii)(B) — 1/5 of the gain multiplied by the amount, if any, by which 4 exceeds the number of preceding taxation years of the taxpayer ending after the disposition. That multiplier is 4 in the year of disposition and falls by one each year, reaching zero in the fifth.
On a total capital gain of $1,800,000, the 25% deferred portion carries a proportionate $450,000 of that gain. In the year of disposition, the reserve is the lesser of (i) the gain reasonably attributable to proceeds payable after year end — here, the full $450,000, since none of the $600,000 note is due until the following year — and (ii) the formula cap of 1/5 × $1,800,000 × 4 = $1,440,000. The lesser figure governs: a $450,000 reserve in year one, deferring tax on that portion of the gain.
The reserve then runs down with the note. After the first $200,000 instalment, $400,000 of the note remains unpaid, carrying a proportionate $300,000 of gain — still well under that year's formula cap of $1,080,000 — so $150,000 of the originally deferred gain is recognized. The same $150,000 is recognized in each of the following two years as the remaining instalments are collected, until the note and the reserve both reach zero in year four. All of it inside the statutory five-year window — with one year of headroom, not three: the formula cap still permitted a reserve of 1/5 × $1,800,000 × 1 in the year after the note was retired, and only reaches zero the year after that.
The deferral is timing, not forgiveness — the seller owes tax on the full $1,800,000 gain regardless, just spread across four tax years instead of recognized entirely in the year of sale. What the vendor take-back actually solved was financing capacity, not tax: the fund could not raise an incremental $600,000 of subordinated capital on the transaction's timeline at terms its investment committee would approve, and the seller's note was the only instrument on the table that closed that gap without external capital.
Without it, the realistic alternatives were a lower headline price sized to what senior debt would actually cover, or the deal not closing on this timeline at all. Either outcome would have cost the seller more than the four-year spread in tax timing did.
The tell was not in the financials. It was the founder's own calendar: no gap longer than three days, across six years of records, is a direct, checkable proxy for how much of the business's earning power is actually transferable. A lender's underwriting model will price that risk whether or not a seller's advisor has thought to address it before the term sheet arrives.
A 30-minute call is enough to tell you whether a structuring or diligence gap like this one is sitting in your pipeline.
