Corporate Merger and Share-Exchange Approval and Filing Requirements in Connecticut

At a glance

Requirements one by one

The merger and share-exchange plans answer different transaction questions

Conn. Gen. Stat. § 33-815 requires a merger plan to identify every merging corporation and the survivor, state the terms, describe how each party's shares convert into securities, interests, obligations, rights, cash, property, or a combination, and set out the survivor's amendments or a new corporation's certificate. Terms may depend on objectively ascertainable outside facts.

Section 33-816 instead covers acquisition of all shares of one or more classes or series. Its plan identifies the acquired and acquiring corporations, states the terms, and supplies the exchange basis. Neither section prevents a separate nonstatutory acquisition transaction, but such a transaction is not a filed § 33-816 share exchange merely because shares change hands.

Board recommendation, quorum, and approval are three separate steps

Under § 33-817(1)-(3), the board first adopts the plan and ordinarily recommends approval. It may condition approval or effectiveness. If conflicts, special circumstances, or § 33-754 justify proceeding without a recommendation, the board must tell shareholders the basis.

At a meeting, § 33-817(5) requires each voting group to have a quorum consisting of a majority of the votes entitled to be cast. Once that quorum exists, § 33-709(c) supplies the ordinary approval result: votes cast for the plan must exceed votes cast against it. The certificate or a board-set condition can require more.

Converted merger classes or series, amendment-equivalent groups, each class or series included in a share exchange, and any certificate-created group vote separately. The certificate may limit some conversion- or exchange-based group rights under § 33-817(7), but not through that provision when the plan combines the specified amendment feature with no substantive business combination.

A corporation formed before January 1, 1997 can remain subject to the special two-thirds rule in § 33-817(13), including a two-thirds vote of certain old classes otherwise lacking a vote, unless its certificate or a statutory no-vote route changes that result.

All-holder notice carries more than the plan

The general calendar in § 33-699 is 10 to 60 days before the meeting. Section 33-817(4) extends transaction notice to every shareholder, voting or nonvoting. The notice states the plan purpose and contains the plan or a summary. If an existing corporation will survive, it also carries that corporation's certificate and bylaws or a summary; a newly created survivor requires the new corporation's materials.

Section 33-698 defaults to unanimous written consent. The certificate may opt in to consent by the meeting-equivalent minimum. Sufficient dated consents must be delivered within 60 days of the earliest signed consent, and the corporation has no more than 10 days after sufficient delivery or later authorized tabulation to send the required materials to nonvoting and nonconsenting holders.

Connecticut's survivor exception has no generic issuance ceiling

Under § 33-817(8), the survivor's shareholders need not approve when the corporation survives, its certificate changes only through the permitted § 33-796 route, and each continuing holder keeps the same number of shares with identical preferences, rights, and limitations. Unlike many states, this text does not add a stock-issuance-percentage test. The other merger party still follows its own approval rule.

For a share exchange, § 33-817(12) excuses the acquiring corporation's holders and excludes shares not being exchanged from the vote, unless the certificate provides otherwise. That does not excuse the acquired corporation or erase the separate voting groups for the shares included in the exchange.

Parent and offer routes are separate from the ordinary plan vote

Section 33-818 lets a domestic parent holding at least 90% of the voting power of every voting class and series merge the subsidiary into the parent or another such subsidiary, or merge the parent into the subsidiary, without the subsidiary board or shareholder approval. Governing certificates and foreign- subsidiary law can change the route. When subsidiary approval is unnecessary, the parent sends each subsidiary holder notice within 10 days after effectiveness.

Section 33-817(10) separately permits an offer-followed-by-merger or share- exchange route when the plan opts in, the offer covers the otherwise-voting shares and stays open at least 10 days, the offeror purchases tendered shares, purchased/owned/committed shares reach every otherwise-required vote, and untendered covered shares receive the same amount and kind of consideration. It is not the ordinary negotiated vote route.

The certificate controls the public effective date

Under § 33-819, every party signs through an officer or other authorized representative. The certificate names the parties and survivor or acquirer, states its effective date and any survivor/new-corporation certificate terms, and recites shareholder and voting-group approval or the applicable no-vote result. The survivor or acquiring corporation delivers it to the Secretary of the State.

Section 33-610 makes an accepted document effective at filing or at the filed time on that date. It also permits a stated delayed date and time, or close of business on a delayed date if no time is stated. That section states no maximum delay, so a 90-day limit from another state's act should not be imported.

Amendment ends at filing; abandonment lasts until effectiveness

Sections 33-815(e) and 33-816(e) let the plan authorize amendments before the certificate is filed. After shareholder approval, the amendment may not change consideration, make barred survivor-certificate changes, or materially harm affected holders through another term change.

Section 33-821a (§ 33-821a) permits any party to abandon after approval but before effectiveness, using the plan's procedure or the corporation's board procedure when the plan is silent, subject to other parties' contract rights. If the certificate is already filed, an officer or authorized representative must file the abandonment statement before the stated effective date.

Appraisal depends on the route, shares, market, and consideration

Section 33-856 can supply appraisal for a voted merger, a merger that skips the vote through § 33-817(10), a § 33-818 subsidiary merger, or the acquired shares in a share exchange. Shares remaining outstanding after a merger and classes not acquired in an exchange fall outside those named branches.

Covered securities, organized-market shares meeting the two-thousand-holder and twenty-million-dollar tests, and redeemable open-end fund shares can be excluded. The consideration and interested-transaction provisions can restore appraisal. Section 33-860 requires the meeting notice or offer to state whether rights are, are not, or may be available and to include the statutory materials when the corporation concludes that rights are or may be available. This page does not decide eligibility, fair value, payment, or preservation for a particular holder.

What trips people up

• The transaction threshold is not simply “majority of outstanding shares.” Each group first needs the majority-of-entitled-votes quorum, then the ordinary result is votes cast for exceeding votes cast against, unless a greater rule applies.
• Nonvoting holders still receive the transaction packet. Their notice right does not by itself create a vote, but a converted or exchanged class may have a separate group right under § 33-817(6).
• Connecticut's survivor exception is not an issuance-percentage test. It turns on survival, permitted certificate changes, and identical continuing holdings.
• The filing can precede effectiveness by more than 90 days. Section 33-610 states no maximum delayed date, and a postfiling abandonment must arrive before that date.

Common questions

May Connecticut shareholders approve by less-than-unanimous consent?

Only if the certificate authorizes that route. Otherwise § 33-698 requires all shareholders entitled to vote. An authorized nonunanimous route uses the meeting- equivalent minimum and carries the 60-day collection and 10-day notice rules.

Does the acquiring corporation vote on a share exchange?

Its board acts, but § 33-817(12) ordinarily excuses its shareholders. The acquired corporation and each exchanged class or series still require the applicable approval unless another route removes it.

Does a 90%-owned subsidiary approve the short-form merger?

Ordinarily no. Section 33-818 removes the subsidiary board and holder approvals when the class-by-class voting-power test is met, subject to the corporations' certificates and any governing foreign law, and requires post-effective notice.
