Changes to the Index composition and/or the component share weights in the Index typically take effect after the close of trading on the next to last business day of each calendar quarter month (“Rebalance Date”). The components and weights will be determined and announced at the close of trading two days prior to the Rebalance Date. This takes place in March, June, September, and December.
In conjunction with the quarterly review, the share weights used in the calculation of the Index are updated based upon current shares outstanding and prices as of the close of trading two business days prior to the Rebalance Date. The share weight of each component in the Index portfolio remains fixed between quarterly reviews except in the event of certain types of corporate actions such as splits, reverse splits, stock dividends, or similar events.
