Methodology Change to the PHLX Semiconductor Sector Index

The NASDAQ OMX Group, Inc. (Nasdaq: NDAQ) today announced a change to the methodology of the PHLX Semiconductor Sector Index (Nasdaq: SOX).

The PHLX Semiconductor Sector Index is designed to track the performance of a set of companies engaged in the design, distribution, manufacture, and sale of semiconductors.

In an effort to ensure that the largest market capitalization eligible securities are included in the Index, NASDAQ OMX will begin conducting an Annual Evaluation. The Index will be evaluated annually in September using market data as of the end of July. The top 30 eligible securities based on market capitalization will be included in the Index. Security additions and deletions will be made effective after the close of trading on the third Friday in September.

The first Annual Evaluation will occur along with the regular September Quarterly Rebalance of the Index. The security additions and deletions will become effective prior to market open on Monday, September 23, 2013. A list of the security additions and deletions will be announced after 8PM ET on Friday, September 13, 2013.
