Which data type would a back office operations unit rely on for corporate actions events?

• A. End of Day pricing files
• B. Corporate actions data
• C. Streaming real-time quotes
• D. Earnings estimates

Answer: (B)

Corporate actions events require data that specifically describes actions companies take affecting shares and cash entitlements. Corporate actions data includes the exact details of each action—its type (dividend, stock split, merger, etc.), key dates (ex-date, record date, payment date), and any adjustments to share quantities or cash flows. The back office relies on this information to automatically update positions, calculate entitlements, adjust trade settlements, and ensure accurate investor statements and regulatory reporting.

End-of-day pricing files are used for valuation and performance calculations, not to drive corporate action processing. Streaming real-time quotes provide intraday price data, which is about pricing as trades occur, not about actions. Earnings estimates are forecasts used for research and planning, not the actionable event details needed for corporate actions processing.
