Members in each index are derived using a qualified universe crafted by PSN. Each index is calculated on a quarterly basis. Returns prior to 12/31/2001 were back-filled to create historical performance results using data provided as of 2/15/02. Each quarter thereafter, the performance return is calculated six weeks after quarter end. Index inception date is constrained by a minimum of 50 qualified products. The list of members in each index may be modified on a quarterly basis to reflect new entrants and products that no longer meet the requirements.
