Morningstar Equity Corporate Actions

Packages in the Corporate Actions category cover all significant corporate events that affect securities — from cash distributions and capital restructuring through to identifier changes and reference data updates. This data is essential for maintaining accurate security master files, adjusting historical time series for corporate events, and tracking the lifecycle of equity instruments. Coverage includes both price-affecting events (dividends, splits, rights issues) and reference changes (CUSIP, SEDOL, ISIN, exchange, and symbol changes).
