A vertical amalgamation that lost its short-form route

Anonymised, illustrative composite. The closing agenda said ‘amalgamate day two’. The share register said something else. CBCA s.184(1) is not a simplified procedure with a tolerance; it is a set of conditions, and one of them was not met by a single share.

At a glance

  • • Federal buyer and federal target; 100% share purchase of a precision-machining business at $11,300,000, with an amalgamation of buyer and target scheduled for the day after closing.
  • • CBCA s.184(1) lets a holding corporation and its subsidiaries amalgamate “without complying with sections 182 and 183” — no amalgamation agreement, no shareholder meeting — on four conditions.
  • • The condition that failed: s.184(1)(a.1) requires that “all of the issued shares of each amalgamating subsidiary corporation are held by one or more of the other amalgamating corporations”. One qualifying share remained registered to the retiring founder.
  • • Falling back to ss.182–183 revives a dissent right: s.190(1)(c) gives a holder the right to dissent where the corporation resolves to “amalgamate otherwise than under section 184”.
  • • Buying in one share for $1 before the resolutions cost nothing. Discovering it afterwards cost seven weeks and an appraisal exposure on a single share of an $11.3 million company.

The situation

A federally incorporated acquisition company bought all the issued shares of a federally incorporated precision-machining business. The plan after closing was ordinary and sensible: amalgamate the two so that the acquisition debt and the operating business sat in the same taxpayer, the bank had one borrower, and the group stopped filing two sets of returns. The closing agenda allowed one line for it, on day two, by directors' resolutions.

The problem

The target's share register showed 1,000,000 common shares transferred to the buyer on closing and one further common share, issued in 2011, still registered to the founder. It had been issued so that a second director could satisfy an internal policy requiring directors to hold shares, and it had survived three reorganisations and two counsel because nobody had reason to look at it.

The share-purchase agreement had been drafted from a capitalisation table, which showed the founder's holding as 100%. It did. The register showed 1,000,001 shares issued, of which the buyer acquired 1,000,000.

The numbers

One share out of 1,000,001 is 0.0001% of the equity, worth about $11 on a pro-rata reading of an $11.3 million price. The cost of it was not the share. It was seven weeks of delay to convene and hold a shareholders' meeting for each amalgamating corporation, roughly $34,000 of legal and corporate-services fees, and an appraisal exposure whose ceiling was not $11 — because a dissenting shareholder is entitled to fair value determined in the statutory process, not to a pro-rata slice of the headline price.

The rule that decided it

CBCA s.184(1) carries the marginal note Vertical short-form amalgamation and opens: a holding corporation and one or more of its subsidiary corporations “may amalgamate and continue as one corporation without complying with sections 182 and 183” if four things are true.

The unit is every issued share of each amalgamating subsidiary, not the controlling block. Paragraph (a.1) requires that “all of the issued shares of each amalgamating subsidiary corporation are held by one or more of the other amalgamating corporations”. There is no threshold, no substantial-compliance language and no de minimis. A single share held by a natural person defeats the route as completely as a 40% minority would.

The other three conditions are set by paragraph (b), and each of them has taken a deal by surprise at some point. The resolutions must provide that the subsidiary's shares “shall be cancelled without any repayment of capital in respect thereof”; that, except as may be prescribed, “the articles of amalgamation shall be the same as the articles of the amalgamating holding corporation”; and that “no securities shall be issued by the amalgamated corporation in connection with the amalgamation and the stated capital of the amalgamated corporation shall be the same as the stated capital of the amalgamating holding corporation”. A vertical short-form amalgamation therefore cannot be used to issue rollover equity, and it cannot be used to adopt the target's articles — the parent's articles survive, always.

What falling back costs is not just process. Section 183 requires the directors of each amalgamating corporation to submit the amalgamation agreement to a meeting of shareholders, with notice complying with s.135, and adoption by special resolution of the shareholders of each corporation. Section 183(3) provides that “Each share of an amalgamating corporation carries the right to vote in respect of an amalgamation agreement whether or not it otherwise carries the right to vote”. And s.190(1)(c) gives a holder of shares of any class the right to dissent where the corporation resolves to “amalgamate otherwise than under section 184”. The short form does not merely save time — it is the reason there is no appraisal remedy.

Two requirements survive either route, and are worth stating because they are often assumed away with the shareholder vote. Section 185(1) applies “after an amalgamation has been adopted under section 183 or approved under section 184”, and s.185(2) requires a statutory declaration of a director or officer of each amalgamating corporation on solvency and creditor prejudice. And s.186 governs the effect in both cases: the property of each amalgamating corporation continues to be the property of the amalgamated corporation, and the amalgamated corporation “continues to be liable for the obligations of each amalgamating corporation”. A short-form amalgamation sheds nothing.

The outcome

Counsel found the share on the pre-amalgamation register review, not at closing. The founder sold it to the buyer for nominal consideration under a one-page transfer, the register was updated, and the s.184(1) route became available again. Total cost: a transfer, a directors' resolution and four business days. Had the resolutions been passed first and the register reviewed afterwards, the amalgamation would have been void for want of a condition and the corrective path would have run through the Director.

The fork: a provincially incorporated target

The Ontario equivalent is OBCA s.177(1), and it is close enough to be quoted from memory and wrong. Three textual differences matter. It dispenses with ss.175 and 176, not ss.182 and 183. Its paragraph (b)(i.1) adds a condition the CBCA does not impose: that “the by-laws of the amalgamated corporation shall be the same as the by-laws of the amalgamating holding corporation”. And its paragraph (b)(iii) requires that “no securities shall be issued and no assets shall be distributed by the amalgamated corporation in connection with the amalgamation” — where the CBCA instead fixes the stated capital at the holding corporation's.

So the same commercial step produces different surviving constating documents in the two jurisdictions. Under the OBCA the parent's by-laws are inherited as a statutory condition; under the CBCA the by-laws are simply not addressed by s.184(1) at all.

The tell

The tell was one digit. A share register showing 1,000,001 issued shares against a capitalisation table showing 1,000,000 is not a rounding difference. The pre-closing check that catches it is reconciling the register — not the cap table, not the schedule to the agreement — to the shares actually being transferred, and doing it before the amalgamation resolutions are drafted rather than after they are signed.

Takeaways

  • • CBCA s.184(1)(a.1) requires all issued shares of each amalgamating subsidiary to be held by the other amalgamating corporations. One share defeats it.
  • • s.184(1)(b) forbids issuing securities on the amalgamation and fixes the articles and stated capital as the holding corporation's — so a short-form vertical amalgamation cannot carry rollover equity.
  • • Falling back to ss.182–183 revives a dissent right under s.190(1)(c), which applies only where a corporation amalgamates otherwise than under s.184.
  • • s.185(2)'s statutory declaration and s.186's continuity of property and liabilities apply either way. The short form saves the agreement and the vote, nothing else.
  • • The OBCA equivalent, s.177(1), adds a by-law inheritance condition and an asset-distribution prohibition the CBCA does not have. Check the statute of incorporation before drafting.
  • • Reconcile the share register, not the capitalisation table, before drafting amalgamation resolutions.
