SCOR share enters "CAC Next 20" index on Paris stock exchange

SCOR, the fifth largest reinsurer in the world, will access the "CAC Next 20" index on 19 June 2009 after market closing. This decision was taken by the "Conseil Scientifique" of NYSE Euronext on 28 May 2009. SCOR will consequently exit the CAC MID100 the same day.

The "CAC Next 20" index represents the next twenty most representative stocks, measured by free-float, capitalisation and liquidity, after the forty stocks in the "CAC 40" index. SCOR is therefore positioned as a potential candidate to enter the "CAC 40" index.

On 28 May 2009 SCOR's market capitalization stood at EUR 2.725 billion. SCOR shares closed yesterday's session at EUR 14.80.

With a performance of -9.48% over the last twelve months (-4.59% including the dividend), SCOR's share price recorded a favourable development compared to the main European share indices, notably compared to the indices for the insurance sector (DJ Insurance index -44.07%; Bloomberg European 500 Insurance -39.39%). Throughout 2008 the title remained liquid with an average daily trading volume of 965,591 shares, representing a daily capital turnover rate of 0.52%.

Today SCOR shares are included in the Dow Jones Europe Stoxx 600 and SBF 120.
