Stoxx Limited, a global index provider and creator of the leading European equity indices, has announced that starting with the September Benchmark Review, component weights in the STOXX Europe 600 Supersector Indices will be capped on a quarterly basis to ensure compliance with UCITS III standards for portfolio diversification.

This change allows passive investment products following the performance of the STOXX Europe 600 Supersector Indices to better track their performance while complying with regulatory requirements.

Each existing STOXX Europe 600 Supersector Index's first component's weight will be capped at 30%, and all remaining component's weights at 15%.

This will ensure compliance with UCITS III standards which require the first component's weight to be less than 35% and all remaining component's weights to be below 20%. No further changes will be made to the indices.

Furthermore, STOXX will launch a set of un-capped supersector indices which will continue to follow the current methodology of the STOXX Europe 600 Supersector Indices without capping of component weights.

These indices are intended to be used for benchmarking purposes and will therefore carry the addition "Benchmark" in their names.

All changes, as well as the introduction of the new un-capped STOXX Supersector Indices will become effective on September 17, 2010.
