Product overview

Unifin Corporate Actions is the corporate action service of the UniFin platform. It serves depositories, CSDs, registrars and custodian banks that keep securities on their own register.

The service runs the whole event. The run covers intake, checks, the announcement and register fixation. Then come entitlement by account, tax withholding, payouts and receipts.

Behind the event logic stand ISO 20022 messages, SWIFT files and the platform bus. Reconciliation, supervisor reporting and the journal follow the same trail.

The service deploys standalone next to an existing depository or CSD. It also runs as a module of the platform and connects to registrars and custodians over their own interfaces.

Inside the platform it shares the register with Unifin Depository. The settlement and payment path is shared with Unifin Collateral and Unifin Payment Bank.

What it delivers

What the solution delivers

From the announcement to the receipt.

Event register

Events arrive from a source system, the desk or a file, and each one opens its own folder. The service keeps the type, the dates and the statuses in one register and shows what waits for confirmation. With the solution the year of events is visible in one place, and every event has an owner. In setup the event types and the calendars come as reference data.

Event terms

A term that is entered late or typed twice puts the payout behind schedule. The service holds rates, dates, formulas, rounding and tax rules, and checks them before the run starts. With the solution the calculation starts on confirmed terms, and a change of terms is journaled with its basis. In setup the formula and the rounding come per event type.

Entitlement

An entitlement is disputed when nobody can retrace the number. The service computes the entitlement from the frozen positions and keeps the record of the run. With the solution every holder sees a figure that can be explained step by step. In setup the official run and the simulation use the same rules.

Tax and payouts

Withholding by hand loses money and time at every payout. The service computes tax per account from the investor profile and runs the payout on the cash and asset leg. With the solution payouts leave on their dates and every event closes with receipts. In setup rates, exceptions and domiciles are configuration.

Elections

A voluntary event lives or dies by the election window. The service opens the window at the announcement, records the option and the volume per account, and closes it at the deadline. With the solution a tender or rights decision is captured with its reason, and reminders go to silent holders. In setup the available options are defined per event type.

Message flow

Participants and downstream systems expect the event in a format they already read. The service exchanges ISO 20022 sese.023 and SWIFT MT564, MT565 and MT566 messages next to the API and files. With the solution the market and the platforms stay in step, and every message leaves a receipt. In setup the addresses and the schedules are configuration.

Reporting

Statements are assembled by hand while the audit waits for the trail. The service builds payout statements, receipts and the journal from the live positions. With the solution the supervisor and the holder get an answer on time, and the audit walks along a ready trail. In setup the form scope and the dispatch schedule stay visible.

How it works

From an announcement to a receipt in five steps

The path of an event: intake, terms, register, calculation, payout.

  1. 1

    The event arrives

    An announcement enters from the source system or the desk.

  2. 2

    Terms are confirmed

    Rates, dates, rounding and tax rules pass their checks.

  3. 3

    The register is fixed

    Positions are fixed on the record date per account.

  4. 4

    The calculation runs

    Entitlement and tax produce a net amount per holder.

  5. 5

    The payout closes

    The cash and asset leg leaves with receipts and statements.

Industries

Industries it serves

The service serves central securities depositories and depositories, registrars and issuers, custodian banks, brokers and asset managers, and the supervisor.

Corporate / issuer

Market access for producers and issuers: auctions, deliveries, tokenised assets and data.

Architecture

Architecture and access

The architecture rests on the corporate action core and the register. Events, terms, entitlement, tax, payouts and the journal.

Service core

The event register, terms, entitlement, tax withholding, payouts, messages and the journal.

Register as the base

Positions come from the depository register, so the entitlement base is the accounts record.

Event bus

Events move with a transactional outbox: announcement, calculation and payout stay in step.

Capacity on the peak

The calculation module runs separately: more than 1,000,000 messages in less than an hour.

AI layer

The AI layer drafts the payout digest and answers questions on event terms; people decide.

Event intake and terms

  • The announcement arrives over ISO 20022 sese.023 or as an MT564 file; the desk can also enter it by hand.
  • The terms carry the rate, the dates, the rounding rule and the tax rules; the formula is checked before the run.
  • A chain holds the events that depend on each other; the service orders the chain and reports per event.
  • The first delivery carries dividends, coupons, redemptions, splits, rights, conversions, buybacks and meetings.

Entitlement and the tax frame

  • The official run takes the actual positions on the record date and produces a line per account and sub-account.
  • Simulation takes theoretical positions over a chain for a selected set of accounts.
  • Tax is computed per account from the investor profile, built on asset type, event type, investor type and domicile.
  • The run record is stored: a calculation can be replayed and explained step by step.

Payouts and receipts

  • Payouts run on the cash and the asset leg in USD, through the payment circuit of the platform.
  • The register is fixed before the payout; a divergence opens a case and holds the payout.
  • Every event closes with receipts and statements per holder.
  • Elections on voluntary events are recorded with the option, the volume and the reason.

Messages and the journal

  • Corporate action messages run over ISO 20022 sese.023 and SWIFT MT564, MT565 and MT566.
  • Throughput is more than 1,000,000 messages in less than an hour; capacity grows by adding nodes.
  • Downstream systems read the outcome from the bus with a transactional outbox.
  • The journal is immutable: it keeps the actor, the time and the basis of every action.

AI layer

  • The AI layer drafts the payout digest and the holder notice from the live positions.
  • Questions on the event terms are answered from the register and the journal.
  • A chain simulation shows the effect of an event on a selected set of accounts.
  • People approve: the agent prepares, the officer decides.
