Methodology Change to the PHLX Semiconductor Sector Index

NEW YORK, Sept. 5, 2013 (GLOBE NEWSWIRE) -- 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.
