Corporate actions sit at the intersection of the front office, middle office, and back office. A dividend payment, a rights issue, or a merger announcement touches positions, valuation models, settlement obligations, and investor reporting all at once. When those processes are managed manually, the risk of errors grows with every additional fund, every additional custodian, and every additional asset class in the portfolio.
For investment operations teams managing large volumes of equity events, corporate actions processing automation is not a luxury, but it is an operational necessity. SimCorp addresses this directly with a configurable Corporate Actions Manager built into its platform architecture.
The Challenge of Managing Equity Events at Scale
Traditional corporate action workflows rely heavily on manual intervention. Operations teams often start their day by logging into custodian websites, gathering event data, and then manually entering that information into position-keeping systems. For basic events like cash dividends, this may be manageable at low volumes. For complex events like rights offerings, mergers with elections, or stock splits across hundreds of positions, the manual approach creates unacceptable risk.
PGGM, a major Dutch investor managing over 20,000 asset lines, described their pre-automation process as highly risky. Staff had to print screen custodian views, circulate them by email, and keep separate spreadsheets updated across front and back office teams.
How SimCorp Configures Corporate Action Workflows
SimCorp’s approach to dividend processing workflow automation centres on the Corporate Actions Manager, a dedicated module that captures, validates, and processes equity events received from multiple data sources. The platform’s architecture supports the full event lifecycle, from announcement through entitlement calculation, election management, settlement, and accounting. Each stage is configurable, allowing operations teams to define business rules without relying on IT departments for every adjustment.
Event Data Capture and Gold Copy Creation

Corporate actions data arrives from multiple sources: custodians, market data vendors, and clearing houses. Reconciling conflicting announcements is one of the most time-consuming parts of the process. SimCorp’s platform addresses this through flexible vendor source hierarchy functionality that enables operations teams to define which data source takes precedence for each event type. Some SimCorp implementations report significantly improved straight-through processing rates for high-volume corporate actions.
Portfolio Impact Assessment and P&L Calculation
Once an event is validated, SimCorp dynamically assesses which portfolios, funds, and individual holdings are impacted. It then updates position, valuation, and exposure data that may affect portfolio performance calculations. This impact assessment feeds directly into the investment book of record and informs risk oversight, giving portfolio managers visibility into how a pending corporate action will affect their positions before settlement occurs.
Election Management for Complex Events
For events requiring investor decisions, such as dividend reinvestment plans, rights issues with oversubscription options, and merger consideration elections, SimCorp provides guided workflows that surface the relevant choices for each portfolio. Election deadlines are tracked automatically, and notifications are generated to ensure that operations teams do not miss critical response windows. Achmea Investment Management, after implementing SimCorp’s standard corporate actions configuration, reported a strongly reduced operational risk and the elimination of manual tasks that had previously created significant key-person dependency.
Processing Mandatory Corporate Actions
For mandatory corporate actions, such as stock splits, bonus issues, and spin-offs, the system automatically starts processing transaction instructions and accounting entries. SimCorp Dimension’s order management and accounting capabilities ensure that corporate actions are accurately reflected in portfolio holdings and financial statements immediately. The creation of dedicated transaction codes for each event type, as implemented by Achmea IM, provides greater transparency and allows teams to book corporate actions in a more logical and efficient manner than legacy approaches permit.
Claim Management and Reconciliation

Corporate action claims management is a critical back-office function, especially in securities lending programmes, where entitlement ownership and payment obligations can involve multiple counterparties. SimCorp’s platform tracks claims across custodians and counterparties, ensuring that entitlements are received or passed on correctly. Reconciliation of corporate action transactions against custodian records is automated, reducing the manual follow-up that typically consumes significant time in operations teams.
Accounting Integration and Audit Trail
Every corporate action event processed through SimCorp generates corresponding accounting entries that feed into the firm’s general ledger and fund accounting records. The audit trail is comprehensive, capturing the source data, the processing decisions made, and the accounting impact of each event. This auditability is particularly important for U.S.-registered investment advisers and Canadian fund managers subject to regulatory scrutiny, where complete documentation of corporate action handling is expected.

Why North American Firms Need Automated Corporate Actions Workflows
North American equity markets generate high volumes of corporate action events. The US market alone sees thousands of mandatory and voluntary events annually, spanning dividends, stock splits, tender offers, and mergers. For asset managers and custodians handling multi-asset portfolios with significant US equity exposure, the operational load is substantial. Canadian firms managing cross-listed securities face the additional complexity of events that may be governed by both TSX and NYSE listing standards simultaneously.
The regulatory environment in both markets also places increasing expectations on the accuracy and timeliness of corporate actions processing. Mishandled events can result in incorrect NAV calculations, mispriced trades, and compliance breaches. Automation reduces these risks significantly by removing the manual steps where errors most commonly occur.
Final Thoughts
Configuring corporate actions workflows end-to-end on SimCorp requires careful setup of event capture, election management, settlement instructions, and accounting integration. When implemented correctly, the platform transforms what was once a labour-intensive and error-prone process into a largely automated and auditable workflow. For investment managers in the UK, US, and Canada managing large equity portfolios, this level of operational control is becoming a baseline expectation rather than a differentiator.
