CDS IndexCo and Markit Announce Official Name Change for New Series of CDX Indices

London and New York – March 16, 2007 – CDS IndexCo LLC (“CDS IndexCo”), a consortium of 16 investment banks licensed as market makers in the CDX indices, and Markit Group Limited (“Markit”), the leading provider of independent data, portfolio valuations and OTC derivatives trade processing, today announced the official name change for the CDX indices.

As previously announced in a press release dated October 27, 2006, the names of the Investment Grade/Emerging Market and the High Yield indices are scheduled to change their names on March 20th and March 27th, 2007, respectively.

As such, the new on-the-run family of CDX indices, previously known as the Dow Jones CDX Indexes will be renamed the CDX Indices. Individually, the names of the actual indices will also change. For example, the Dow Jones CDX North American Investment Grade Index (DJ CDX.NA.IG) will simply be renamed the CDX North America Investment Grade Index (CDX.NA.IG). The off-the-run series of CDX indices with an effective date prior to March 20, 2007 will continue to carry the Dow Jones name or mark.

Also as previously announced, Markit will continue to act as Calculation Agent, and will retain responsibility for the administration of CDS IndexCo. Since the October 27, 2006 announcement, Markit has taken on the additional responsibility of licensing the CDX Indices. The transfer of responsibilities and the subsequent name change will not affect trading or index composition in any way.

The CDX family of credit derivative indices are composed of corporate and sovereign entities domiciled in North America and the Emerging Markets, and include:

CDX.NA.IG (Investment Grade)

n CDX.NA.IG.HVOL (High Volatility)

n CDX.NA.HY (High Yield)
