Recalculation Policy

Index recalculation may be necessary due to:

  • Delayed or corrected input data from exchanges
  • Errors in index calculation
  • Retrospective corporate actions

Our recalculation policy is as follows:

  1. Intraday Recalculation: Errors detected within the same trading day will be corrected and the index recalculated as soon as practicable.

  2. End-of-Day Recalculation: Errors affecting end-of-day index values will be corrected and recalculated if detected within two business days.

  3. Historical Recalculation: Errors in historical data will be assessed on a case-by-case basis. Recalculation will occur if the error significantly impacts index performance or composition.

All recalculations will be clearly communicated to index users, detailing the reason, extent, and impact of the recalculation.
