News release
Converium Holding Ltd, Zug

Zug, Switzerland - February 28, 2007 - Converium reports 2006 income from
continuing operations of USD 215 million, net income of USD 57 million and
presents its value-focused medium-term strategy.

Converium today presents its road map to generate a sustainable return on equity
of 14% by 2009. The key elements of Converium's medium-term value creation
strategy are: growing business volume to USD 3 billion by 2009, whilst reducing
the combined ratio to 96%; boosting capital efficiency by seeking shareholder
approval to return USD 300 million to shareholders through the use of hybrid
capital; increasing returns on investment and further improving cost-efficiency
of operations.

Converium's value creation strategy is supported by a strong financial
performance in 2006, with the following highlights:

o    USD 215.0 million income from continuing operations
o    USD 57.1 million net income, including the negative impact from
     discontinued operations, net of tax of USD 157.9 million
o    USD 1,980.9 million gross premiums written
o    96.3% non-life combined ratio
o    USD 1,846.0 million shareholders' equity
o    CHF 0.20 per share proposed dividend for 2006

Inga Beale, CEO, commented: "I am very pleased with our strong financial results
for 2006. Based on a robust franchise and significant operational improvements
we have accomplished a remarkable turnaround. I am convinced that the strategic
path charted today sets both ambitious and obtainable goals. It rests on a
capital base of approximately USD 2 billion, sound operating profitability,
strong support from clients and brokers as well as talented employees who are
committed to capturing the growth opportunities following a ratings upgrade. I
strongly believe that we can achieve our growth and profitability targets based
on the comprehensive management of all relevant value drivers."

Converium's road map for sustainable value creation

Converium is committed to achieving a sustainable return on equity of 14% by
2009. The underlying strategy will be built on fundamental improvements in
underwriting, capital management, asset management and operations.

Growing the business while improving profitability

Converium aims to grow its gross premiums written by more than one third to USD
3 billion by 2009 based on total gross premiums written for 2007, expected to be
in the range of USD 2.2 billion. Converium expects to win back a significant
share of business with existing customers following a ratings upgrade. The
Company expects to be able to regain market share in all lines of business, but
primarily in specialty areas such as Credit & Surety and Agribusiness where
Converium used to be among the global leaders. In addition, the Company expects
to capture opportunities from fast-growing emerging markets where Converium can
build on strong client relationships and a regional infrastructure.

Converium is further committed to improving underwriting profitability to a
combined ratio of around 96% in 2009. This objective is expected to be achieved
based on the following four elements: First, the fronting fee on Converium's
Global Aerospace Underwriters Ltd (GAUM) business will decrease following a
ratings upgrade; second, the long-tail business with the Medical Defence Union
(MDU) which is economically profitable even at a combined ratio of more than
100% will lose weight in Converium's overall portfolio; third, following a
ratings upgrade, the Company is committed to rebalancing its book of business
towards non-proportional business and attractive


                                       1





specialty lines at lower expected combined ratios; and, fourth, with growing
business volumes Converium expects a reduced administrative expense ratio.

Boosting capital efficiency by returning capital to shareholders and using more
hybrid capital

Following a ratings upgrade, Converium will be in a position to more efficiently
leverage its balance sheet. Converium currently has significantly lower balance
sheet leverage than its peers. The Company will seek to take advantage of
beneficial financing conditions, and, shortly after a ratings upgrade, issue
hybrid debt to USD 500 million. The funds raised will refinance current
outstanding hybrid debt, and allow for USD 300 million to be returned to
shareholders following shareholder approval. Greater efficiency in the use of
capital is expected to bring down the weighted average cost of capital to under
9% by that date.

Converium believes that its overall capital situation will allow for a
sustainable dividend pay-out ratio of 25%-35%.

Increasing sustainable investment yield

Based on Converium's state-of-the-art expertise in Asset-Liability-Management
and its new strategic partnership with Deutsche Asset Management, the Company
expects to achieve significant sustainable improvements in its investment yield.
One of the specific measures envisaged is a more sophisticated management of
Converium's fixed-income securities portfolio.

Strong financial performance in 2006

Income from continuing operations up six-fold

For 2006, Converium reported income from continuing operations of USD 215.0
million compared with USD 34.1 million for the same period in 2005, equivalent
to 13.0% return on equity. Converium's 2006 figures demonstrate the quality of
the Company's underlying book of business, the absence of any major catastrophic
events, as well as a satisfactory net investment income. The significant
increase in profit is driven by an improvement in the non-life combined ratio
from 107.0% in 2005 to 96.3% in 2006. In addition, Converium's results were
positively impacted by the net favorable impact of prior accident years on the
technical result of USD 52.1 million. Net income for 2006 amounted to USD 57.1
million, reflecting an overall negative impact on net income of USD 157.9
million from the sale of Converium's North American operations.

Growth in business volume reflective of stable franchise

For the year ended December 31, 2006, gross premiums written increased by 1.3%
to USD 1,981 million. Net premiums written increased by 3.9% to USD 1,852
million, showing a resilient franchise and visible progress made towards the
Company's turnaround in 2006. However, net premiums earned decreased by 19.7% to
USD 1,812 million due to lower earned premiums from prior underwriting years
reflecting the impact of the ratings downgrade in 2004. For the year ended
December 31, 2006, net premiums written in Standard Property & Casualty
Reinsurance increased by USD 77.9 million, or 10.5%, Specialty Lines decreased
by USD 8.3 million, or 1.1% and net premiums written in the Life & Health
Reinsurance segment decreased by USD 0.7 million, or 0.2%.

Satisfactory net investment income result and investment yield (continuing
operations)

Converium's net investment income from continuing operations increased by 1.0%
to USD 260.4 million for the year ended December 31, 2006 as compared with USD
257.8 for the same period in 2005. The average total invested assets from
continuing operations was USD 6,147.4 million, which was a slight increase on
the 2005 amount of USD 6,139.1 million. Our average net investment income yield
(pre-tax) from continuing operations for the year was 4.2%, comparable with the
prior year, reflecting similar market conditions and asset allocation.


                                       2





Fourth quarter performance impacted by sale of US operations

The net loss in the fourth quarter of 2006 was USD 121.3 million, reflecting the
one-off negative impact from the loss on sale of Converium's North American
operations in December of 2006 of USD 190.1 million. The return on equity from
continuing operations was 14.9%, compared with 4.2% for the fourth quarter of
2005. Gross premiums written over the quarter were USD 428.1 million, an
increase of 10.7% on the prior year quarter. The combined ratio for the fourth
quarter of 2006 was 93.5%, benefiting from the absence of major natural
catastrophes during the period.

Considerations on SCOR's pre-announcement: Converium's strategy expected to
deliver more value

The Board of Directors of Converium has noted the announcement of an offer by
SCOR, at CHF 21.1 per share, for the whole of the share capital of Converium,
based on closing share prices at February 16, 2007,

-------------------------

(1)  Continuing operations information (including prior periods presented)
     excludes the operating results of the North American operations and the
     loss on sale of Converium Holdings (North America) Inc. in the fourth
     quarter of 2006.

(2)  Included in loss on sale are net unrealized losses on available-for-sale
     securities, the currency impact and deferred income tax balance of USD 18.6
     million that previously have been recognized in other comprehensive income
     (equity) and are realized upon the sale of the North American operations.

(3)  Segment income is defined as net premiums earned plus total investment
     results minus losses, loss expenses and life benefits, acquisition costs
     and other operating and administration expenses, excluding Corporate
     Center.

(4)  Non-life combined ratio is defined as ongoing non-life loss ratio (to net
     premiums earned) plus ongoing non-life acquisition costs ratio (to net
     premiums earned) plus ongoing non-life administration expense ratio (to net
     premiums written).

(5)  Based on shareholders' equity from continuing operations at the beginning
     of the period.


                                       3





that was published on February 26, 2007. The Board strongly believes that the
offer fails to recognize Converium's full stand alone value potential. In
addition, the Board stresses the fact that Converium offers shareholders
potential value upside due to its flexibility to return capital.

Converium's Board considers SCOR's acquisition currency to be weak: the cash
part of SCOR's offer would be financed by Converium's excess capital and
Converium shareholders would assume significant risk with a stretched combined
balance sheet. Further, given the significant stock element in the offer,
Converium shareholders would require more visibility on SCOR's stand alone value
potential.

Converium's Board of Directors is convinced that the Company's current share
price does not reflect its full upside value following a ratings upgrade which
Converium has made great progress to achieving on its own. SCOR's unsolicited
approach also entails incalculable business and integration risk.

Converium's 2006 Annual Report will be available in electronic format on 20
March 2007. The Annual General Meeting is planned to take place on 10 May 2007.
