Corporate Actions and CASS Client Asset Safeguarding Explained

E.3 Corporate Actions

In Plain Words

Corporate actions are events that a company causes, such as dividends, splits or takeovers. The Corporate Actions team turns each event into what every holder is entitled to, and for voluntary events it collects each holder’s choice before the deadline. A missed election is usually a loss the firm has to repay.

Why it matters: A missed deadline here is rarely forgiven, and the firm pays for it.

In Brief

Summary: Corporate Actions turns issuer events into each holder’s entitlement and collects elections on voluntary events before the deadline. A missed election is usually a loss the firm repays.

  • Mandatory events happen to every holder; voluntary ones need a decision.
  • Deadlines shorten at every link in the custody chain.
  • Entitlements are fixed on the record date position.
  • Announcements are checked against a second source to build a golden record.

Two lists: mandatory events happen to every holder; voluntary events need a decision, a missed election is usually a loss the firm repays, and deadlines shorten at every link in the custody chain
Figure e.3.1 · Mandatory and voluntary corporate actions

Corporate Actions (part of asset servicing) captures every event an issuer applies to its securities, works out what each holder is entitled to, collects elections from clients or portfolio managers, and books the result. Events split into mandatory ones, which happen to every holder (cash dividends, stock splits, mergers for cash or stock, coupon payments), and voluntary ones, which need a decision by an election deadline (rights issues, tender offers, dividend reinvestment, conversions). The function exists because these events change positions and cash without any trade, so nothing else in the firm will catch them.

⚡ Why It Matters

A missed voluntary election is a loss the firm usually owes the client in full, and on a large holding one missed deadline can cost more than a year of the team’s small errors. Deadlines compress at every link: the issuer’s agent sets a deadline, the depository sets an earlier one, and each custodian sets an earlier one still, so the client may have a day or two to decide. Mandatory events carry a quieter risk: on US exchanges the ex-dividend date is usually the record date itself, so a trade done the day before still carries the dividend, and if that trade fails, the entitlement must be claimed from the counterparty.

🧮 Worked Example: An Entitlement and a Missed Election

The process: capture the announcement; validate terms against a second source; on record date, fix the eligible position (settled holdings plus or minus pending trades); calculate the entitlement; notify and collect elections for voluntary events; instruct the custodian before its deadline; book and reconcile the payment or new shares on pay date.

A fund holds 12,000 shares. The issuer pays a $0.85 dividend and launches a one-for-five rights issue at $40.00 while the shares trade at $52.00.

StepFormulaResult
Dividend (mandatory)12,000 × $0.85$10,200 (before any withholding)
New shares the rights allow12,000 ÷ 52,400
Cost to take them up2,400 × $40.00$96,000
Theoretical ex-rights price (TERP)(5 × $52.00 + $40.00) ÷ 6$50.00
Value of the rights2,400 × ($50.00 − $40.00)$24,000

If the election is missed and the rights lapse without compensation, the holding falls from 12,000 × $52.00 = $624,000 to 12,000 × $50.00 = $600,000: a $24,000 loss. Had the fund subscribed, it would hold 14,400 shares worth 14,400 × $50.00 = $720,000 for $624,000 + $96,000 invested, so no loss. The firm that missed the deadline usually compensates the $24,000.

As of Oct 2026: ex-dividend date usually equals the record date (investor.gov). Corporate-action messages: ISO 20022 “seev” messages (seev.031 CorporateActionNotification, seev.033 CorporateActionInstruction, seev.036 CorporateActionMovementConfirmation) alongside the older ISO 15022 SWIFT formats; DTCC publishes its corporate-actions specifications in ISO 20022. Golden-source vendors include LSEG, alongside the depository’s own feeds.

🔗 Reporting Lines & Key Interactions

Reports to: the Head of Asset Servicing or Securities Operations under the COO; at custodian banks, a large business line in its own right.

Typical direct reports: leads for announcements and data, mandatory events and income, voluntary events and elections, claims, and tax.

Key interactions:

Outside finance: portfolio managers, client service, tax, custodians and the depository.

Core systems: a corporate-actions platform with a golden-record engine, vendor and depository feeds, custodian portals, SWIFT messaging.

Where this work sits: GBS/GCC teams in Bengaluru, Hyderabad, Pune and Chennai typically scrub announcements, calculate entitlements and book income; onshore teams keep client-facing election handling and sign-off on high-value voluntary events. The control consequence is a hard rule that no deadline is missed during the handoff: elections are tracked on one shared calendar with escalation hours before each cutoff.

E.4 Client Assets and Safeguarding (CASS Oversight)

In Plain Words

Client Assets keeps customers’ money and securities separate from the firm’s own, and proves it every day. In the US, the rule is SEC Rule 15c3-3. In the UK, it is CASS 6 and CASS 7.

Why it matters: A daily proof is what keeps client assets safe if the firm fails.

In Brief

Summary: Client Assets keeps client money and securities apart from the firm’s own and proves it daily. In the US that is SEC Rule 15c3-3; in the UK, CASS 6 and CASS 7.

  • CASS 7: daily internal client money reconciliation; any shortfall funded by close of business.
  • Larger US broker-dealers compute the customer reserve daily, others weekly.
  • Under SM&CR a named senior manager is accountable for CASS.
  • The SEC withdrew its 2023 adviser safeguarding proposal in June 2025.

Two lists: in the US SEC Rule 15c3-3 requires larger broker-dealers to compute the customer reserve daily and others weekly; in the UK CASS 6 and CASS 7 require a daily internal client money reconciliation and any shortfall funded by close of business
Figure e.4.1 · Client asset rules in the US and UK

Client Assets makes sure that money and securities the firm holds for clients are kept apart from the firm’s own, recorded client by client, and reconciled often enough that clients would get them back in full if the firm failed. It exists because a broker that mixes client cash with its own can lose it to its creditors in an insolvency. The US rule for broker-dealers is the SEC’s customer protection rule, Rule 15c3-3: securities held for customers must be in the firm’s possession or control, and customer cash, net of what customers owe, sits in a special reserve bank account. In the UK the equivalent is the FCA’s Client Assets Sourcebook (CASS): CASS 6 for custody assets and CASS 7 for client money. This is the only chapter covering UK rules, because many firms run UK entities from the same teams.

CadenceWhat Actually Happens
DailyInternal client money reconciliation (CASS 7: every business day, on the previous day’s records) and same-day funding of any shortfall; for larger US broker-dealers, the reserve computation; reviewing breaks that touch client accounts
WeeklyThe standard US reserve computation (for firms below the daily threshold); oversight meeting on open client-asset breaks
MonthlyExternal client money reconciliation and custody record checks (CASS: at least monthly); the Client Money and Asset Return (CMAR) to the FCA within 15 business days of month-end; acknowledgment letters for new client bank and custody accounts
QuarterlyReporting to the board or risk committee; control testing; breach review
AnnuallyThe auditor’s client assets report to the FCA (within four months of period-end); the US investment adviser’s surprise custody examination by an independent accountant; refreshing the CASS resolution pack, which must be retrievable within 48 hours of an insolvency
⚡ Why It Matters

When a broker fails, segregation decides whether clients are paid from their own protected pool or join the queue of general creditors. A shortfall found today is a firm problem only if it is funded today: CASS 7 requires any shortfall shown by the internal reconciliation to be paid into a client bank account by close of business on the day the reconciliation is done, and material failures must be notified to the FCA without delay. Accountability is personal: under the Senior Managers and Certification Regime (SM&CR), CASS compliance is an FCA-prescribed responsibility given to a named senior manager.

As of Oct 2026: CASS 1A.3 requires CASS medium and large firms (client money of at least £1 million or custody assets of at least £10 million) to give one director or senior manager the CASS operational oversight function, often called the CASS Officer. SEC Rule 15c3-3 requires a daily reserve computation for broker-dealers with average total credits of $500 million or more (weekly otherwise), with any deposit due one hour after banking opens on the second following business day. Advisers follow the custody rule, Rule 206(4)-2 (qualified custodian, annual surprise examination); the SEC’s 2023 proposal to replace it was withdrawn on June 17, 2025. India: SEBI has required stock brokers to upstream clients’ funds to clearing corporations at end of day since July 1, 2023 (circular of June 8, 2023, revised December 12, 2023). Sources: FCA Handbook, CASS 7.15; CASS 1A.3; SUP 3.10; CASS 10.1; 17 CFR 240.15c3-3; 17 CFR 275.206(4)-2; SEC withdrawal notice; SEBI circular, Dec 12, 2023.
🧮 Worked Example: The Daily Client Money Reconciliation

The process (CASS 7 standard method): take yesterday’s close-of-business records; compute the client money requirement (what the firm should hold for clients, built client by client); compare it with the client money resource (the balance in client bank accounts per the firm’s records); fund any shortfall or withdraw any excess the same day; separately, at least monthly, reconcile the firm’s records of client bank accounts to the banks’ statements.

LineFormulaResult
Client money requirementSum of client balances, by client$48,640,000
Client money resourceClient bank account balances, firm records$48,515,000
Shortfall$48,640,000 − $48,515,000$125,000

The firm transfers $125,000 of its own money into the client bank account before close of business, then finds the cause (here, a client withdrawal paid from the client account before the client’s sale proceeds had arrived). The US analogue: if a broker-dealer’s reserve formula shows customer credits of $900 million against customer debits of $760 million (ignoring the formula’s adjustments), it must hold $900 million − $760 million = $140 million in the reserve account; with $130 million on deposit, it deposits $10 million by the rule’s deadline.

🔗 Reporting Lines & Key Interactions

Reports to: the daily reconciliations sit in operations or finance; the oversight function reports to the named senior manager, often the COO or CFO, with direct access to the board and the risk or audit committee. Part 0: The Map of Finance places it as a control function over back-office processing.

Typical direct reports: client money and custody reconciliation leads, a regulatory returns lead (CMAR, reserve computation), a policy and testing lead.

Key interactions:

Outside finance: legal (acknowledgment letters, insolvency analysis), internal audit, external client-assets auditors, banks and custodians.

Core systems: the client ledger, the reconciliation engine, banking portals and the regulatory reporting tool.

Where this work sits: GCC teams in Bengaluru, Pune and Hyderabad typically prepare the daily reconciliations, reserve computations and returns. Onshore staff keep the funding decision, breach assessment and the accountable senior manager’s sign-off, because the accountability is personal and the regulator expects the named person to understand the controls.
