Inga Beale, Chief Executive Officer comments: "In the first half year 2007 Converium has continued to perform strongly. Adjusting for the one-off release of the tax valuation allowance, we have achieved a return on equity of over 13%. The extremely satisfying July renewals results and the most recent set of figures testify to the strength and solidity of the company that is now part of the SCOR Group." Solid second quarter 2007 results For the second quarter of 2007, Converium reported a net income of USD 46 million. The results were driven by a robust underlying underwriting performance which helped to absorb the expenses relating to the SCOR transaction of USD 24 million. Converium reported an increase in net income of USD 72 million to USD 197 million for the six months ended June 30, 2007 as compared with the same period in 2006. These 2007 figures reflect a net tax benefit of USD 67 million mainly due to the release of the tax valuation allowance in Switzerland amounting to USD 75 million. Solid technical underwriting performance and overall reserve position Gross premiums written in the second quarter of 2007 came in at USD 490 million, an increase of 5% compared with the second quarter of 2006, as Converium started to benefit from strong growth in markets such as Latin America and the Middle East. For the six months' period, there was an 8% increase in premium volume from USD 1,115 million to USD 1,202 million. The second quarter's non-life combined ratio was 96.6% compared with 98.8% for the same period of 2006. For the six months ending June 30, 2007 the non-life combined ratio came in at 100.5%, compared with 97.8% for the same period of 2006. The combined ratio for the first half of 2007, on a normalized basis - excluding prior year development impact of USD 16 million or 2.1% as well as impact from natural cat losses above plan by USD 31 million or 4.3% - comes in at 98.3%, which is below the full year target of 98.5%. Converium continued to profit from favorable prior accident year developments. The positive impact of prior accident years on the technical result was USD 11 million for the second quarter 2007, compared with USD 29 million for the same period in 2006. For the first six months the respective figures are USD 16 million and USD 43 million. In the first half of 2007, unfavorable adjustments in the motor line of business were more than offset by positive developments in property, aviation and space, engineering and credit and surety. Overall the total level of reserves remains supported by the independent actuarial report conducted during the first quarter. Increase in business volume in all lines of business In the largest business segment, Standard Property & Casualty Reinsurance reported gross premiums written of USD 648 million during the first six months of 2007, up 16% compared with the same period of the prior year. Its segment income of USD 37 million for the first half of 2007, down from USD 90 million in 2006, was adversely affected by losses from natural catastrophes Storm Kyrill in Europe of USD 50 million and New South Wales Australian flood related losses of USD 11 million. In addition, in 2007 the segment saw a unfavorable net impact of prior accident years' development on technical result of USD 35 million, mainly driven by the negative impact in prior year loss reserves in the motor line of business of USD 41 million, partially offset by a positive development in prior year loss reserves in the property line of business of USD 21 million. These developments are reflected in the segment's combined ratio in the first half year of 107.7%, up 18.6% against the last year period. In Specialty Lines, for the second quarter 2007, gross premiums written slightly increased by 3% despite a drop of 33% in aviation & space where business did not meet Converium profitability targets. The segment reported positive prior accident years' developments on the technical result of USD 51 million for the first half 2007, mainly in the aviation & space, engineering and credit & surety lines of business. In the first six months of 2007, a combined ratio of 93.0% was recorded, compared with 106.1% in the same period of the prior year. The Life & Health Reinsurance segment posted a technical result of USD 20 million in the first half of 2007, as compared with USD 14 million a year earlier (USD 11 million vs. USD 8 million on quarterly comparison). All major markets contributed to the positive development. Gross premiums written grew to USD 79 million in the quarter or USD 211 million in the first six months of 2007, an increase of 22% compared with the first half of 2006, largely driven by increasing business within the European Markets. Solid total investment result In the second quarter of 2007, Converium reported a total investment result of USD 86 million, compared with USD 63 million for the same period of 2006. For the six months ending June 30, 2007 the respective figures are USD 178 million and USD 123 million. In the second quarter of 2007 total investment income yield was 5.3%, compared with 4.3% in the same period of 2006. For the six months ended June 30, 2007 the respective yields are 5.5% and 4.1%. As of June 30, 2007, Converium had no direct or structured indirect fixed maturity securities exposure to the US subprime mortgage credit market. Further improvement of capital strength As of June 30, 2007, Converium had total shareholders' equity of USD 2,017.2 million (USD 13.78 per share) compared with USD 1,846.0 million (USD 12.63 per share) as of December 31, 2006, an increase of USD 171.2 million (USD 1.15 per share). Extraordinary transaction costs In the wake of Converium's acquisition by SCOR, the Company recorded non-recurring transaction costs in the second quarter of 2007 of USD 24 million, or USD 31 million for the first six months respectively, primarily related to legal, consulting and investment banking fees. Successful July non-life renewals In the latest July 1 renewals Converium achieved an excellent growth of 34% or USD 21 million, bringing total renewed open market business to USD 85 million. This increase in premium was mainly recorded in the property line of business where Converium managed to regain previously lost business and to generate new business, particularly in Australia, the Middle East and Latin America. Overall, the Company was successful in capturing the momentum following the restoration of its A- financial strength rating by Standard & Poor's on February 28, 2007. As of August 8, 2007, SCOR, as a shareholder, formally controls the company. Enquiries Beat W.
