The company did not meet the selection criteria when the index was last reconstituted. Companies that now meet index selection criteria will become candidates for inclusion at the next reconstitution date.

Eligible initial public offerings will be considered for inclusion on the index’s next scheduled reconstitution date.  In the event of an IPO which the index committee deems has “high importance” for the EQM Metals and Mining Index, the index committee can decide to include these companies on an extraordinary adjustment event basis.

If an index component’s stock is discontinued due to a merger or acquisition, the index committee may, at its sole discretion, replace the discontinued component at the time of discontinuation if more than 30 calendar days remain until the next reconstitution date.  The discontinued component will either be deleted entirely or be replaced with the next eligible security from a reserve list.  The replacement will be given the appropriate weighting given the securities country of domicile. If there are not more than 30 calendar days remaining until the next reconstitution date, the index committee will wait until the next reconstitution date to make the replacement.  In this scenario, any funds received from the discontinued security will be distributed to the remaining index components pro rata.

The index is rebalanced quarterly and is scheduled for reconstitution on the second Wednesday of August, November, February, and May.
