A management buyout the deeming rule turned non-arm's-length

Anonymised, illustrative composite. A transaction every party genuinely believed was arm’s length, decided by a rule that does not ask what anyone believed.

At a glance

  • • Ontario, four senior managers bought 100% of the shares of the specialty distributor they ran, through a newly formed acquisition vehicle, Newco, for $7,400,000.
  • • The founder-vendor kept a 15% rollover stake in Newco alongside the four managers — a common way to bridge a valuation gap and keep her involved through the transition.
  • • s.84.1(2)(b) deems the vendor not to deal at arm’s length with Newco where she was one of fewer than six persons controlling the target before the sale, and one of fewer than six controlling Newco after it.
  • • With the founder inside Newco’s five-person controlling group, the deeming rule applied — and s.84.1(1)’s paid-up-capital grind and deemed-dividend formula engaged on a sale every party had modelled as a clean, arm’s-length exit.
  • • The fix was structural: reducing the founder’s continuing stake below what put her inside the controlling group removed the deeming and the deal, restructured, went ahead as originally priced.

The situation

Four senior managers of a specialty distribution business — the general manager, the head of sales, the controller and the operations lead — had run the company for a decade under its founder, who was ready to retire. Rather than sell to an outside strategic buyer, the founder agreed to sell to the four of them through a newly incorporated acquisition vehicle, Newco, at a price of $7,400,000.

To bridge a gap between the founder’s asking price and what the four managers could finance, and to keep her available through an eighteen-month transition, the founder agreed to roll 15% of her proceeds into Newco equity rather than take the full purchase price in cash. Every party’s advisors treated the transaction as an arm’s-length sale — a departing owner selling to unrelated buyers — and priced it accordingly, including the paid-up capital the new shares would carry.

The problem

s.84.1(2)(b) does not ask whether the parties dealt with each other honestly, at a negotiated price, without collusion — the ordinary common-law markers of arm’s length. It asks a narrower, mechanical question: “the taxpayer shall, for greater certainty, be deemed not to deal at arm’s length with the purchaser corporation if the taxpayer” “was, immediately before the disposition, one of a group of fewer than 6 persons that controlled the subject corporation” and “was, immediately after the disposition, one of a group of fewer than 6 persons that controlled the purchaser corporation”, where each member of the second group also belonged to the first. The founder had been the sole controlling shareholder of the target before the sale — trivially one of a group of fewer than six — and, holding 15% of Newco alongside the four managers, was one of a group of five controlling Newco afterward.

Both conditions were met on facts nobody disputed. The deeming rule does not require intent to avoid tax, does not care that the price was independently negotiated, and does not distinguish a genuine management buyout from an artificial one — it looks only at group membership before and after.

The numbers

Purchase price $7,400,000: $6,290,000 cash to the founder plus $1,110,000 of Newco rollover equity, the 15% stake. Once s.84.1(2)(b) deemed the sale non-arm’s-length, s.84.1(1) applied its paid-up-capital grind to the new Newco shares issued to the founder and computed a deemed dividend on the cash portion in place of ordinary capital-gains treatment — converting a substantial part of the $6,290,000 cash proceeds from a taxable capital gain, eligible in part for the lifetime capital gains exemption, into a deemed dividend, which is not.

The rule that decided it

Read the unit: s.84.1(2)(b) is a deeming rule for greater certainty — it exists specifically to catch structures where a nominal buyer entity conceals continuity of control by the vendor, including the common case of a founder keeping a minority stake in the buying group. It bites regardless of whether the transaction is, in every commercial sense, a genuine arm’s-length sale. Four managers with no prior ownership stake buying the company they worked for is exactly the kind of transaction most people would call arm’s length — and it still falls inside the deeming rule the moment the vendor holds equity in the buying group alongside fewer than six total controlling persons.

The fork that resolves it: without the founder taking any rollover equity in Newco, she is not a member of the group controlling the purchaser corporation after the sale, and the deeming rule has nothing to attach to — s.84.1 does not apply at all on that structure, and the sale proceeds are ordinary capital gains proceeds. The cost of that fix is real: it means the founder cannot keep the continuing stake the parties actually wanted her to have, and the deal has to be restructured around all-cash consideration or a different mechanism for her continuing involvement, such as a consulting agreement rather than equity.

The outcome

The parties restructured before closing: the founder took her full proceeds in cash rather than rollover equity, and her continuing involvement through the transition was papered as a fixed-term consulting agreement rather than an ownership stake in Newco. That removed her from Newco’s controlling group entirely, took the transaction outside s.84.1(2)(b), and preserved the capital-gains treatment — and the exemption eligibility — on the full $7,400,000. See rollover equity that changed the seller’s answer for a structure where keeping rollover equity was the right call because the buyer, not the vendor, controlled the acquisition vehicle.

What it would have cost otherwise

Closing on the original structure would have left a meaningful share of the $6,290,000 cash proceeds taxed as a deemed dividend rather than a capital gain, with no access to the lifetime capital gains exemption on that portion, and a paid-up-capital figure on the founder’s Newco shares too low to support a future tax-free return of her remaining equity.

The tell

The tell was a headcount, not a behaviour: nobody on the deal team had counted how many people would control Newco immediately after closing, or checked that number against the founder’s own pre-sale control of the target — the two facts s.84.1(2)(b) actually asks about.

Takeaways

  • • s.84.1(2)(b) deems non-arm’s-length dealing on a mechanical fewer-than-six-persons test, regardless of whether the transaction is a genuine, independently negotiated buyout.
  • • A vendor who keeps rollover equity in the buying entity, alongside fewer than six other controlling persons, falls inside the deeming rule — count the controlling group on both sides before assuming arm’s length.
  • • Removing the vendor from the purchaser’s controlling group — typically by taking cash instead of continuing equity — takes the transaction outside s.84.1(2)(b) entirely, at the cost of the continuing stake itself.
  • • A consulting agreement, rather than equity, is one way to keep a departing owner involved through a transition without triggering the deeming rule.
