Effective on the next rebalance on December 29, 2006, NEX Index's methodology will be updated. Please see the following text for the updated methodology.

The Index is calculated using a modified equal-dollar weighting methodology. At the time of rebalancing each Index sector is assigned an overall weight in line with that sector's market capitalization within the NEX's component selection universe, adjusted if necessary to avoid problems of illiquidity or over-concentration on any individual sector. All components are limited individually to five percent (5%) of the Index by weight at rebalancing notwithstanding any other rules. Each sector's components are divided into two categories, large and small. Large components are given three and half times the weight of small components within their sector, and are defined as having an individual market capitalization over $750 million. Components may be reassigned between large and small categories within their relevant sectors at the discretion of the Index Committee in order to alleviate concerns of individual component liquidity or restricted availability. Components quoted on those markets that restrict ownership or trading by foreign investors will not be excluded altogether but may be allocated to the small component category within their respective sectors. *As of the September 2006 rebalance, India and China restrict ownership or trading by foreign investors.
