The deadline in the offer is never the one that binds

IBKR closes Arbutus four hours early, and Lindsell Train’s tender shut to buyers before its circular came out. Both dates, worked through.
99 SHARES Issue #3
Sunday 20 September 2026 · prices are Friday 18 September closes from the broker’s daily bars · deadlines in New York time with the market-local time beside them · annualised figures are per trade
Corrections, 20 Sep 2026. Issue #2 said every Lindsell Train holder may tender a fifth of their shares, with cash on 16 October. The circular opens the tender only to shares on the register at 6 p.m. London on 14 September, and pays through CREST on 20 October; 16 October is completion. The lesson below works it through. Issue #2 also printed our Air Canada purchase at C$28.04; the fill was C$28.03. And the broker’s records now put our two realised losses at −C$24.95 and −US$323.10, against −C$24.86 and −US$322 printed.

The deadline in the offer is never the one that binds

Albert Gasull, editor · Sunday 20 September 2026

Every tender offer prints an expiry on its front page. Two of our own trades this week show that the dates which decide the outcome are set somewhere else: by the broker, which stops taking instructions early, and by settlement, which decides who is on the register when eligibility is counted. One of them cost us the trade we bought for.

This week’s funnel: 11 filings and headlines caught in seven days → 6 live offers reachable at our broker → 1 new (Medtronic).

The lesson

How the broker’s cutoff and the record date work

An offer’s expiry is the moment the depositary, the agent collecting shares for the buyer, stops accepting them. Almost nobody tenders to the depositary directly. The shares sit with a broker, the broker sits inside a central depository (DTC in New York, CREST in London), and each link needs time to collect, net and pass on instructions. So the broker closes first, and the offer documents say so in a sentence most readers skip:

The sentence in the filing

“If an investment dealer, stock broker, bank, trust company or other nominee holds Shares for a Shareholder, it is likely the nominee has established an earlier deadline for that Shareholder to act to instruct the nominee to accept the Offer on its behalf.”

Arbutus Biopharma, Offer to Purchase, Schedule TO-I exhibit (a)(1)(i), August 2026

Arbutus: offer expires Tue 29 Sep, 17:00 New York
Arbutus: IBKR’s cutoff Tue 29 Sep, 13:00 New York
Oma Savings Bank: offer ends Fri 25 Sep, 09:00 New York (16:00 Helsinki)
Oma: IBKR’s cutoff Wed 23 Sep, 03:00 New York (10:00 Helsinki), about 2 days earlier
Delivery Hero: acceptance ends Thu 5 Nov; IBKR Tue 3 Nov, 2 days earlier
Medtronic: offer expires midnight New York, end of Fri 9 Oct; DTC expected to close at 17:00, 7 hours earlier
What that means for an Arbutus holder an instruction sent at 14:00 New York on 29 Sep is inside the offer and outside the broker’s window, so the shares stay untendered

The gap has no rule behind it. Through one broker it has been four hours, two days and two days, and it appears in no offer document: the only source is the broker’s own corporate-action notice, published after the offer opens. Even the offer’s own dates can move. On 17 September Medtronic filed an amendment to correct “a typographical error” in its guaranteed-delivery deadline, which now reads “5:00 p.m., New York City time, on the second New York Stock Exchange trading day after the date of execution”.

The same plumbing sets a second date, at the other end. A US tender lets whoever holds the shares at the cutoff tender them. A UK trust tender often fixes eligibility on a register date instead, and a register counts only shares that have settled. Lindsell Train’s tender is open to shareholders “in respect of Shares held by them on the Tender Record Date”: 6 p.m. London on Monday 14 September. London settles two business days after the trade.

The sentence in the filing

“Basic Entitlements will be calculated by reference to registered shareholdings of Eligible Shareholders as at the Tender Record Date and will be rounded down to the nearest whole number of Shares.”

The Lindsell Train Investment Trust plc, tender offer circular, 11 September 2026

Tender Record Date Mon 14 Sep, 13:00 New York (18:00 London)
Settlement trade date + 2 business days
Last trade date that settled in time Thu 10 Sep
Circular published Fri 11 Sep
Our purchase 260 shares, Mon 14 Sep, 08:00 New York (13:00 London); settled Wed 16 Sep
Shares we expected to tender (20% of 260) 52
Shares we can tender 0

Issue #2 missed this, and so did we. We bought the 260 shares for the tender, and they settled two days after the register was counted. The position is now an ordinary holding in a trust at a discount, and the route to 95% of net asset value is closed to these shares. It has cost nothing yet (Friday’s 590p is above our 578p average), but it is no longer the trade we described.

The rule

Two dates decide whether a holder is in a tender, and neither is the expiry on the front page. The record date, where there is one, counts settled shares only, so the purchase has to be made at least two business days before it. The broker’s cutoff falls hours or days before the expiry and appears only in the broker’s own notice, once the offer is open.

Two earlier lessons apply to every case below: odd-lot priority (issue #1) and the Canadian paid-up-capital test (issue #2). This week’s lesson has its own guide: broker cutoffs and record dates.

This week’s situations

Live offers with terms and a deadline, each worked through with the same arithmetic.

Arbutus ABUS
Nasdaq, Canadian issuer · modified Dutch auction self-tender, US$230m · odd-lot priority under 100 shares
Price → offer $5.01 (18 Sep close) → clears between $5.00 and $5.75
Gross −0.2% at the $5.00 floor, where Friday’s price sits / +7.3% at the $5.375 mid / +14.8% at the $5.75 top
Annualised, this trade −4% at the floor; ~148% at the mid; over 18 days to expected cash (~6 Oct)
Costs US: no stamp duty; broker minimum about $1, 0.2% of 99 shares
Tax check Canadian issuer. Paid-up capital is estimated at not less than C$8.42 a share; the top of the range is C$8.04 at Friday’s USD/CAD of 1.3987, so no deemed dividend unless the rate passes 1.464
Broker cutoff IBKR 29 Sep 13:00 New York
offer expires 29 Sep 17:00 New York
What it shows The lesson’s four-hour gap. Friday’s price at the floor of the range suggests the market expects the auction to clear near $5.00, not at the mid. Odd lots tendered in full are taken in full, at the clearing price.

NEW  Medtronic MDT → MiniMed MMED
NYSE, Irish company · split-off exchange offer · odd-lot priority under 100 shares
Price → offer MDT $92.13, MMED $21.79 (18 Sep closes) → about $107.53 of MMED for each $100 of MDT, on the 5–7 Oct average prices, capped at 4.5939 MMED per MDT
Gross +7.5% at Friday’s prices. The cap binds if MMED falls about 1% against MDT; at MMED $21.00 the gross is +4.7%
Annualised, this trade ~106% over 26 days to delivery and sale of the MMED shares (~14 Oct), if the cap does not bind
Costs No Irish stamp duty on trades settled through DTC (Form 10-K); the prospectus expects no Irish withholding or stamp duty on the exchange; broker minimum about $1 a leg. 99 shares is a ~$9,100 ticket
Broker cutoff IBKR: not yet posted
DTC expected open to 17:00 New York on 9 Oct; offer expires at midnight New York, end of 9 Oct
What it shows A split-off: Medtronic swaps the MiniMed shares it owns for its own shares at a 7% discount. It expects oversubscription, and the prospectus exempts odd lots: “beneficial holders of less than 100 Medtronic Ordinary Shares who validly tender all of their shares will not be subject to proration.” The risk sits in the prices, not the terms: MDT until the averaging days, MMED until the new shares are sold, and a cap 1% away.

Oma Savings Bank OMASP
Helsinki · recommended cash tender by S-Bank · all regulatory approvals received
Price → offer €17.14 (18 Sep close) → €17.20 cash
Gross +0.35%

Broker cutoff IBKR Wed 23 Sep, 03:00 New York (10:00 Helsinki)
offer ends Fri 25 Sep, 09:00 New York (16:00 Helsinki)
What it shows The lesson’s two-day gap. One condition remains, acceptances above 90%, which the bidder may waive. The final result is due about three Finnish banking days after expiry, completion within five banking days after that.

NYSE · plan of liquidation · shareholder vote 29 Sep
Price → offer $6.42 (18 Sep close) → an estimated $7.75–8.50 a share still to be paid
Gross +20.7% to +32.4%
Annualised, this trade ~12–18% simple, if the last payment lands by mid-2028
Costs US: none; broker minimum about $1
Broker cutoff No election
vote Tue 29 Sep, 10:00 New York
What it shows A liquidation is an estimate, not an offer: the range is the company’s and the timeline is long. The first payment, $3.70–4.00 a share, is expected about 30 days after approval. For non-US holders the proxy calls liquidating distributions “generally not subject to U.S. federal income tax”; the trap is a later liquidating trust, whose interests cannot be transferred.

Killed, and why

US fund self-tenders, for a non-US taxable account. Virtus NFJ (25% at 99% of net asset value, expires 5 Oct 17:00 New York), XAI XFLT (12.5% at 98% of NAV, expires one minute after 11:59 p.m. New York on 19 Oct) and Herzfeld HERZ (5% at 97.5% of NAV, expires 15 Oct 17:00 New York). All three are pro rata, none gives odd lots priority, and all three warn of US withholding for non-US holders. NFJ puts it plainly: “The Fund may withhold 30% of the proceeds otherwise payable to a Foreign Shareholder.” At Friday’s prices the tendered slice is worth 17.0% more than the market in XFLT (98% of the $22.95 NAV of 11 Sep, against $19.23) and 19.3% more in HERZ (97.5% of the $19.13 NAV of 31 Aug, against $15.64); 30% of the proceeds is larger than either. None of this applies to a US taxable holder. Next time: read the paragraph on non-US shareholders before the discount.

Iveco. Friday’s €14.106 close is above Tata’s €14.10 offer, which includes the dividend. Nothing is left to capture. A market above the offer is pricing something else, usually a higher bid.

Computer Modelling Group. A C$4.00–4.50 Dutch auction on the TSX, expiring Monday 21 Sep at 17:00 New York. Friday’s close was C$4.00, the floor. We never read its paid-up-capital sentence, because the circular is filed only on Canada’s SEDAR+, and a broker cutoff up to two days early has probably passed. Next time: the tax sentence gets read the week a bid opens, not the week it closes.

Clywedog Therapeutics (formerly Beacon Topco). A fixed-price tender at $6.6609 with odd-lot priority, expiring 29 Sep 17:00 New York. Our broker had no contract for the new line on 20 Sep, so it can be neither priced nor traded here, and the document warns of 30% withholding for non-US holders.

Lindsell Train, for anyone who bought after 10 September. The lesson above.

Priority Income Fund. The tender is for common shares that “are not currently traded on an established trading market”; the listed lines are preferred shares.

And the noise. Two of the week’s eleven rows were Docebo’s final results for a bid that closed on 8 September, re-published as news. One was Precision Drilling’s normal course issuer bid, an open-market buyback with nothing to tender into.

The book — our own money

Open: ABUS 99 at $5.05, tendered at the purchase price · ARI 300 at $6.92 · Oma 300 at €17.07, elected for cash at €17.20 · Delivery Hero 50 at €37.04 · Lindsell Train 260 at 578p, bought for the tender and not eligible for it.

Closed this week: no special-situation position. Realised losses to date, from the broker’s records: Air Canada −C$24.95, sold 11 September; Zevia −US$323.10, sold 10 September.

Editor’s view: the Lindsell Train mistake is cheap so far and expensive in principle, because we read a register date as if it were a trade date.
