Corporate Actions

Corporate actions are either mandatory (such as cash dividends, stock splits, coupon payments and mergers), voluntary (such as tender offers and rights subscriptions, where the holder must elect) or mandatory with options (such as dividends payable in cash or shares). Each event affects positions, cost basis, cash or all three.

Operations teams capture announcements from data vendors and custodians, validate key dates such as ex-date, record date and pay date, calculate entitlements, submit elections by deadline, and update the IBOR and ABOR. Missed or misprocessed events are a common source of reconciliation breaks and NAV errors.

Pitfalls include conflicting data between vendors, missed election deadlines on voluntary events, incorrect cost-basis adjustments, and withholding tax differences on dividends. A four-eyes review on elections and entitlement calculations is standard practice. Golden-copy event data is a common control.

Example

A fund holds 1,000 shares priced at $80. The issuer announces a 2-for-1 stock split. After the ex-date the fund holds 2,000 shares priced at about $40; market value is unchanged at $80,000, and cost basis per share is halved.
