Cash Dividend
DVCA
Distribution of cash to equity holders out of company profits or reserves, in proportion to shareholding. The most routine, highest-volume corporate action any Ops desk processes.

Mechanics & Entitlement
Entitlement = record-date position × dividend rate per share. Currency conversion applies if paid in a currency other than the holder's base currency; some issuers offer a currency election.
Settlement & Accounting Impact
Cash credited to the account, typically net of withholding tax deducted at source per the holder's tax residency/treaty documentation; gross and net amounts are both reported. Pure cash event — no position movement.
Real-world exampleQuarterly dividends from NYSE, LSE and NSE blue chips are almost all plain DVCA events — the single highest-volume corporate action type any custodian handles.
Mandatory
Stock Dividend & Bonus Issue
DVSE / BONU
Distribution of additional shares to existing holders — instead of cash (stock dividend) or free of payment on top of the existing holding (bonus/capitalisation issue) — in proportion to holding. Markets mainly distinguish the two by accounting source (retained earnings vs. share premium/reserves) and tax treatment.

Mechanics & Entitlement
New shares = holding × bonus ratio, usually rounded down with the fraction paid as cash-in-lieu. Market price is adjusted down on ex-date proportionate to the dilution — total position value is roughly unchanged.
Settlement & Accounting Impact
Free-of-payment securities credit; no cash movement aside from fractional cash-in-lieu. Average cost per share is recalculated by spreading the original cost basis across the new, larger share count.
Real-world exampleIndian issuers frequently issue bonus shares (e.g., ratios like 1:1); each event increases share count and reduces market price proportionally, leaving pre-market-movement holding value unchanged.
Mandatory with Choice
Dividend Reinvestment (DRIP) / Scrip Dividend
DRIP / DVOP
A cash dividend where the holder may elect to receive newly issued or market-purchased shares of equivalent value instead of cash — or, in a scrip structure, shares by default with a cash option.

Payment / Allotment
Mechanics & Entitlement
Election is per holding; if silent, the issuer's stated default (usually cash) applies. Share entitlement = elected cash amount ÷ a reinvestment reference price, often set at a small discount to market.
Settlement & Accounting Impact
A cash-electing holder is processed exactly like a DVCA. A stock-electing holder gets a FoP securities credit instead, with the cash amount recorded internally as "reinvested" — still relevant for tax reporting even though no cash actually moved.
Real-world exampleDRIP programmes are common with income-focused blue chips and REITs, letting long-term holders compound their position without brokerage costs on each reinvestment.
Mandatory
Stock Split (Forward)
SPLF
Each existing share is subdivided into a larger number of shares (e.g., 10-for-1), reducing the price per share proportionally with no change to total investment value or market cap.
AnnouncementSplit ratio declared

Record Date

Ex-Date / Effective DateRatio applied
Mechanics & Entitlement
New holding = old holding × split ratio. Reference price is divided by the same ratio — a re-denomination of the same economic interest into more units.
Settlement & Accounting Impact
Position increased via a free-of-payment event; no cash movement. Average cost per share is divided by the ratio so total cost basis is unchanged; exchanges auto-adjust open orders and limit prices.
Real-world exampleNvidia executed a 10-for-1 forward split effective 7 June 2024 — a holder of 100 shares became a holder of 1,000 at one-tenth the price. Amazon carried out a 20-for-1 split in June 2022.
Mandatory
Reverse Stock Split
SPLR
The opposite of a forward split — existing shares are consolidated into a smaller number (e.g., 1-for-10), raising the per-share price proportionally. Often used to meet an exchange's minimum-price listing rule or reduce an unwieldy share count.

Record Date

Ex-Date / Effective Date
Mechanics & Entitlement
New holding = old holding ÷ consolidation ratio, rounded down; fractional shares are almost always cashed out rather than issued, since exchanges don't trade in fractions.
Settlement & Accounting Impact
Position reduced via a FoP event; fractional entitlement paid as cash-in-lieu at the post-split reference price; average cost per share is multiplied by the ratio.
Real-world exampleGeneral Electric executed a 1-for-8 reverse split in 2021; Citigroup executed a 1-for-10 reverse split in 2011 following its post-financial-crisis share count.

Rights Issue
RHTS
The issuer offers existing shareholders the right — not the obligation — to subscribe for new shares, usually at a discount to market, in proportion to their holding. Raises fresh capital while preserving existing holders' pre-emption rights.

Allotment / Listing
Mechanics & Entitlement
Holders have three real choices: subscribe (pay the price for new shares), sell the renounceable rights entitlement in the market, or let it lapse. Unsubscribed rights are often sold by the agent for non-participants (the "rump"), or simply lapse depending on the market.
Settlement & Accounting Impact
On subscription: cash debited, new (sometimes partly-paid) shares credited, often under a temporary ISIN until fully paid and merged into the parent line. If rights are sold instead, cash is credited and no new position is created.
Real-world exampleReliance Industries raised ₹53,124 crore via a rights issue in May 2020 — 1 new share for every 15 held at ₹1,257 per share, payable in instalments — one of the largest global rights issues that year.

Tender Offer / Share Buyback

Settlement Date
Mechanics & Entitlement
Holders elect how many shares to tender. If total tendered exceeds the offer's cap, shares are accepted pro-rata across all tendering holders; untendered or prorated-back shares remain outstanding, unaffected.
Settlement & Accounting Impact
Accepted shares debited from custody, cash credited at the tender price; any unaccepted portion simply remains in the account. Odd-lot holders are sometimes given priority to avoid leaving small residual positions.
Real-world exampleFixed-price and Dutch-auction tender buybacks are a standard capital-return tool for large-cap issuers alongside open-market repurchases; Dell's 2013 going-private deal used a tender/merger structure.
Voluntary
Dutch Auction Buyback
DTCH
A variant of the tender offer where the issuer specifies a price range rather than a single price; holders tender at whatever price within the range they'd accept, and the issuer sets the single "clearing price" that lets it repurchase the targeted amount.

Mechanics & Entitlement
Every accepted tender is paid the same clearing price, regardless of the price the holder specified, as long as their bid was at or below the clearing price. Oversubscription at the clearing price is prorated.
Settlement & Accounting Impact
Identical mechanics to a standard tender offer once the clearing price is set: shares debited, cash credited at the single clearing price.
Real-world exampleDutch-auction structures are used when an issuer wants price discovery from its own shareholder base rather than dictating a single premium upfront.

Entitlement = holding × agreed cash-per-share price. Any trade in the target still open on the effective date is transformed from a securities deliverable into the cash equivalent.
Settlement & Accounting Impact
Target shares extinguished (debited) from custody; cash credited at the agreed price; the security is delisted from its exchange.
Real-world examplePfizer's ~$43bn all-cash acquisition of Seagen closed in December 2023. Twitter's take-private deal (October 2022) was an all-cash merger at $54.20 per share.

Mechanics & Entitlement
Because the aggregate cash/stock mix is fixed at deal level, an individual holder's election can be prorated if too many choose the same option — cash electors scaled back and topped up with stock, or vice versa. Non-electing holders receive a pre-set default mix.
Settlement & Accounting Impact
A composite of the cash-merger and stock-merger mechanics above, applied per the final prorated allocation once the election window closes.
Real-world exampleBroadcom's acquisition of VMware (closed November 2023) let VMware holders elect $142.50 cash or a fixed ratio of Broadcom shares per share, prorated to keep the overall consideration roughly half cash, half stock.
A parent company distributes shares of a subsidiary ("spinco") pro-rata to its existing shareholders, creating a new, independently listed company. Economically similar to a stock dividend, but the distributed security is a different, newly listed entity.

Spinco Trades Independently
Mechanics & Entitlement
Distribution ratio (e.g., 1 spinco share for every 4 parent shares) is fixed by the parent's board. No cash changes hands; the parent's price is marked down on ex-date to reflect the value distributed.
Settlement & Accounting Impact
A new position (in the spinco, under its own ISIN) is credited FoP to the same account; the parent's cost basis is split between parent and spinco shares based on their relative fair values at distribution — a genuinely fiddly tax-lot exercise.
Real-world exampleGeneral Electric spun off GE HealthCare in January 2023, then split its remaining businesses into GE Aerospace and GE Vernova in April 2024 — one issuer running the mechanic twice in under two years.

Warrant Exercise
EXWA
A warrant gives its holder the right to buy the underlying share at a fixed strike price before expiry. Exercise is entirely at the holder's discretion — economically like a call option, but warrants are issued directly by the company (dilutive) rather than traded as standardised derivatives.

Holder pays the strike price per warrant exercised; new shares are issued by the company (dilutive), unlike an exchange-traded option settled between existing market participants.
Settlement & Accounting Impact
Cash debited (strike price × warrants exercised), new shares credited FoP; unexercised, out-of-the-money warrants simply lapse worthless at expiry.
Real-world exampleSPAC (special-purpose acquisition company) warrants are a high-volume, retail-heavy example of EXWA processing — holders weigh exercising against the current share price ahead of expiry.

Delisting & Name / Ticker Change
DLST / CHAN
Delisting removes a security from an exchange (voluntarily, by regulatory action, or following a merger); a name or ticker change (CHAN) simply updates identifying information with no economic effect on the holding.
Announcement
→
Effective Date
Mechanics & Entitlement
Ticker/name change: position is entirely unaffected — only static data updates across custody and trading systems. Delisting following a merger: closed out through the merger's own settlement, not through DLST alone.
Settlement & Accounting Impact
Name/ticker change — no cash or position movement, purely a static-data update. Standalone delisting (e.g., regulatory) — no automatic entitlement; impact is on liquidity and valuation, not settlement.
Real-world exampleA company rebranding its legal name and ticker triggers a CHAN event across every custodian's static data with zero cash or position impact — the clearest example of a purely informational corporate action.
Voluntary
AGM / EGM Voting

No cash or securities movement whatsoever — MEET is purely an instruction-and-reporting workflow, still handled through the same MT564/565/567 message family.
Real-world exampleA merger's shareholder-approval vote is itself a MEET event that must pass before the underlying MRGR event can proceed to its effective date — procedurally linked, operationally distinct.
The company is wound up — assets sold, liabilities settled, and any residual value distributed to shareholders (who rank behind creditors and preferred holders) in one or more liquidating distributions. In a full liquidation, the equity is ultimately extinguished.

Final Distribution / Cancellation
Mechanics & Entitlement
There may be one final payment or several interim liquidating distributions as assets are realised over time; the per-share amount is rarely known precisely in advance.
Settlement & Accounting Impact
Cash (occasionally in-kind assets) credited to holders as distributions occur; the equity position is debited to zero once the final distribution is paid and the security is cancelled.
Real-world exampleCommon outcome for closed-end funds and distressed/bankrupt issuers once a court-approved winding-up plan is in place; equity holders typically recover little or nothing if the company was insolvent, since creditors are paid first.
