Euronext: Amendment To AEX-, Midkap- And All-Share Index Ground Rules

Date 31/01/2003

Euronext Indices B.V. announces the following rule changes for the AEX-index, the Amsterdam Midkap index and the Amsterdam All-Share index.
  1. The amendment of the AEX-index and the Amsterdam Midkap index regards a transfer of the responsibility of settlement price calculation. This responsibility will be transferred from Euronext Indices B.V. to Euronext Amsterdam N.V.

    The settlement procedure will be deleted from the AEX-index ground rules and the Amsterdam Midkap index ground rules. The procedure can still be found in the Reference Book of Euronext Amsterdam Derivative Markets.

    The rule changes for the Amsterdam All-Share index are the following:

  2. Date of review and effective date will be synchronised with the schedule of the AEX-index and Amsterdam Midkap index.
  3. Date of review of the Amsterdam All-Share Smaller Companies index will be synchronised with the schedule of the AEX-index and Amsterdam Midkap index. In addition, the effective date will be the first trading day after the review date.
  4. The description and specification of the complete Amsterdam All-Share index series will be moved to chapter 1 of the ground rules.
  5. The date of the periodical reclassification of the stocks qualifying for the Amsterdam All-Share Sector indices will remain the third Friday of the month; effective the second trading day of the following month. As a result the review date of the Amsterdam All-Share Smaller Companies index and the Amsterdam All-Share Sector Indices will no longer coincide. A new chapter with specific rules on the Amsterdam All-Share Smaller Companies index will therefore be included.
  6. Euronext Indices B.V. has taken the opportunity to implement some minor updates, clarifications and corrections.
The exact changes are included in the appendix to this announcement.

In view of the three-month notification period, all changes will come into effect on 1 May 2003.
