ITEM 3. KEY INFORMATION

A. SELECTED FINANCIAL AND OTHER DATA

We have prepared our financial statements included in this annual report in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). The following financial data highlights selected information that is derived from our financial statements as of and for the years ended December 31, 2006, 2005, 2004, 2003 and 2002.

The selected financial and other data should be read in conjunction with the Consolidated Financial Statements and related notes and with “Management’s Discussion and Analysis of Financial Condition and Results of Operations”.

Converium currently manages its business around three operating segments: Standard Property & Casualty Reinsurance, Specialty Lines and Life & Health Reinsurance, which are based principally on global lines of business. In addition to the three segments’ financial results, the Corporate Center carries certain administration expenses, such as costs of the Board of Directors, the Global Executive Committee and other corporate functions as well as expenses not allocated to the operating segments. In addition to reporting segment results individually, management also aggregates results for Standard Property & Casualty Reinsurance and Specialty Lines into non-life business, as management considers this aggregation meaningful in understanding the performance of Converium.

In 2004, Converium’s North American operations were placed into orderly run-off and reported as the Run-Off segment to monitor this business on a stand-alone basis. On December 13, 2006, Converium sold its North American operations to National Indemnity Company, a Berkshire Hathaway company, for total consideration of USD 295.0 million comprising of USD 95.0 million in cash and USD 200.0 million in assumption of debt. Converium has not provided any guarantee or indemnity in respect of the reserves of the North American operations. The transaction was approved by the Insurance Department of the State of Connecticut. Our North American operations were previously reported as the principal component of a separate segment, the Run-Off segment. Converium’s financial results of the North American business, including prior period amounts, have been reclassified to discontinued operations. For further details regarding the sale of the North American operations, see Note 2 to the consolidated financial statements.

D. RISK FACTORS

Risks relating to Converium and the reinsurance industry

If we do not successfully implement our strategy or if such strategy is not effective, it could have a material adverse effect on our business, financial condition, results of operations and cash flows

As a multi-line reinsurer Converium pursues a strategy of profitable organic growth with a geographic emphasis on Europe, Asia-Pacific, Central and South America, and the Middle East. Reflecting its significant capabilities in this particular area, the Company places a distinct focus on global specialty lines. Converium implements its strategy by:

–

Making investments in specialty lines: Based on the Company’s track record and human capital Converium is committed to further expanding its specialty portfolio, including Aviation & Space, Engineering, Marine & Energy, Credit & Surety and Agribusiness.

–

Maintaining and developing multiple distribution channels, including joint ventures: To leverage Converium’s proven skills at identifying and managing joint ventures and distribution channels which provide direct access to business, the Company will continue to seek opportunities in this field. This offers growth opportunities beyond organic business development and outright acquisitions.

–

Broadening the client base: In addition to expanding relationships with existing clients Converium seeks to establish new relationships in the Company’s preferred geographical markets and lines of business.

–

Expanding the knowledge base: Converium believes in the value of a knowledge-based business model, offering clients insight and services beyond pure underwriting capacity. To this end, the Company will continue to boost its intellectual capital.

–

Further enhancing the risk management and control culture: These efforts will focus on further implementing a state-of-the-art Enterprise Risk Management (“ERM”) framework.

–

Advancing cost and capital efficiency: Converium is committed to further rationalize its internal processes and setup in order to achieve a competitive administrative expense ratio. In addition, Converium constantly seeks to maximize capital efficiency by exploring opportunities for leveraging its balance sheet and transferring risks directly to the capital markets.

There can be no assurance, however, that we will be able to successfully implement our strategy or that the strategy will be effective. The implementation and the effectiveness of this strategy are based on a certain number of assumptions (including continued client acceptance outside the United States) and factors that are not under our control. If economic conditions, our competitive position, our rating level or our financial condition are not consistent with these assumptions or our objectives, or if the measures envisaged by the strategy are insufficient, it is possible that our strategy would fail and that we would not achieve our objectives. In this case, our business and financial condition could deteriorate and new measures would need to be devised and implemented.

A ratings downgrade could have a material adverse effect on our business, financial condition, result of operations or cash flows

If our ratings were significantly downgraded, our competitive position in the reinsurance industry may suffer, and it could be more difficult for us to market and sell our products. Certain business that we write contains terms that give the ceding company the right to terminate cover and/or require collateral if our ratings are downgraded. A significant downgrade could result in a significant reduction in the number of reinsurance contracts we write and in a substantial loss of premium volume as client companies and brokers that place their business, move to other competitors with higher ratings.

The claims paying ability ratings assigned by rating agencies to reinsurance or insurance companies are based upon factors and criteria established independently by each rating agency. Rating agencies may downgrade or withdraw their ratings in the future if we do not continue to meet the then current criteria for the ratings previously assigned to us. Such criteria may change, perhaps significantly, at the sole discretion of the rating agencies.

Based on the developments in 2004, Standard & Poor’s Ratings Services lowered its rating of Converium, including its subsidiaries, to BBB and following the rights offering changed this rating to BBB+. On March 1, 2007 Standard & Poor’s raised the rating to A- (Stable Outlook). Although A.M. Best placed its rating of Converium on watch with a positive outlook on September 7, 2006, it continues to rate the Company at B++, the level to which it was downgraded in 2004.

Claims-paying ability and financial strength ratings are a key factor in establishing the competitive position of reinsurers. The Company believes that the A- rating from Standard & Poor’s is sufficient but that the B++ rating from A.M. Best may not satisfy the criteria required by some of its target clients and brokers, and that this rating may negatively impact new business and adversely affect its ability to compete.

In the light of changing business circumstances associated with Converium’s ratings downgrade in 2004, Converium entered into fronting agreements with Munich Re and National Indemnity Company in order to support and sustain the aviation business from GAUM. Converium expects that continuation of its membership in GAUM will be supported by its rating upgrade from Standard & Poor’s but to some extent may still be conditional upon entering into fronting arrangements acceptable to other pool members in a timely fashion and thereafter maintaining such arrangements. Converium has currently two fronting arrangements in place, both with National Indemnity Company and Munich Re. The current fronting agreement covers the GAUM business written in the US and Canada and is effective from January 1, 2007 until December 31, 2007. The other fronting agreement is for GAUM business written outside the US and Canada and was originally effective from January 1, 2007 until June 30, 2007 and has now been renewed for the period until December 31, 2007.

We cannot guarantee that we will be able to maintain the A-rating from Standard & Poor’s and, in the case of a rating downgrade by Standard & Poor’s by two notches to below BBB+, Converium’s membership in GAUM pool would be reduced to less than a 5% share. In such a case, Converium would not be permitted to participate in future pool business and would have to collateralize, through letters of credit, its obligations under the business written by the pool in its name prior to its termination. If Converium’s pool membership were terminated, it would also be required to sell its 30.1% stake in GAUM. In 2006, this business generated USD 230.8 million of gross premiums written. See Notes 7 and 17 to our 2006 consolidated financial statements for additional information on GAUM.

Our loss reserves may not adequately cover future losses and benefits

Our loss reserves may prove to be inadequate to cover our actual losses and benefits experience. To the extent loss reserves are insufficient to cover actual losses, loss expenses or future life benefits, we would have to add to these loss reserves and incur a charge to our earnings which could have a material adverse effect on our financial condition, results of operations or cash flows.

Loss reserves do not represent an exact calculation of liability, but rather are estimates of the expected cost of the ultimate settlement of losses. All of our loss reserve estimates are based on actuarial and statistical projections at a given time, facts and circumstances known at that time and estimates of trends in loss severity and other variable factors, including new concepts of liability and general economic conditions. If the underlying assumptions used do not hold true over time, actual losses could vary, possibly materially, from the estimates.

As of December 31, 2006, we had USD 6,348.6 million of gross reserves and USD 5,743.7 million of net reserves for losses and loss expenses. If we underestimated these net reserves by 5%, this would have resulted in an additional USD 287.2 million of incurred losses and loss expenses, before income taxes, for the year ended December 31, 2006.

Unforeseen losses, the type or magnitude of which we cannot predict, may emerge in the future. These additional losses could arise from newly acquired lines of business, changes in the legal environment, or extraordinary events affecting our clients such as reorganizations and liquidations or changes in general economic conditions. We continue to conduct pricing, loss reserving, claims and underwriting studies for many casualty lines of business, including those in which preliminary loss trends are noted. Converium has experienced moderate favorable developments of its loss reserves. Since 2002, Converium has recorded USD (425.6) million of favorable development from continuing operations on prior year’s non-life business (2002: USD (113.9) million; 2003: USD (195.7) million; 2004: USD 72.8 million; 2005 USD (86.0) million; and 2006 USD (102.8) million). The positive reserve development within 2006 was largely within the Property line of business, primarily within the underwriting years 2003 and 2004 as well as the aviation line of business, primarily within the underwriting years 2002, 2003 and 2004.

In addition, because we, like other reinsurers, do not separately evaluate each of the individual risks assumed under reinsurance treaties, we are largely dependent on the original underwriting decisions made by ceding companies. We are subject to the risk that our ceding companies may not have adequately evaluated the risks to be reinsured and that the premiums ceded to us may not adequately compensate us for the risks we assume.

We may be unable to meet the collateral requirements necessary for our business

In November 2004, Converium AG obtained a USD 1.6 billion, three-year syndicated letter of credit facility (the “Syndicated Letter of Credit Facility”) from various banks. The facility provides Converium’s operating companies with a USD 1.5 billion capacity for issuing letters of credit and a USD 100.0 million liquidity reserve. As of December 31, 2006, Converium had outstanding letters of credit of USD 1,974.5 million under the Syndicated Letter of Credit Facility and other bilateral letter of credit arrangements. Investments of USD 1,973.5 million were

pledged as collateral related to the Syndicated Letter of Credit Facility and other irrevocable letters of credit of USD 769.1 million (to secure certain assumed reinsurance contracts). Converium must comply with various financial covenants in order to avoid default under the agreement. In an event of default, the majority lenders may cancel the total commitment and/or may declare that all amounts outstanding may be immediately due and payable and that full cash cover in respect of each letter of credit is immediately due and payable.

See “Item 3. — Key information — D. Risk factors – Ratings changes” for information on collateral requirements related to GAUM and Notes 7 and 17 to our 2006 consolidated financial statements.

We are subject to the cyclical nature of the reinsurance industry

The insurance and reinsurance industries, particularly the non-life market, are cyclical. Historically, operating results of reinsurers have fluctuated significantly because of volatile and sometimes unpredictable developments, many of which are beyond their direct control. These developments include:

•		price competition and price setting mechanisms of clients;

•		frequency of occurrence or severity of both natural and man-made catastrophic events;

•		levels of capacity and demand;

•		general economic conditions; and

•		changes in legislation, case law and prevailing concepts of liability.

As a result, the reinsurance business historically has been characterized by periods of intense price competition due to excessive underwriting capacity as well as periods when shortages of underwriting capacity permitted attractive premium levels. We expect to continue to experience the effects of cyclicality, which could have a material adverse effect on our business, financial condition, results of operations or cash flows.

Securitization trend could disadvantage medium-sized players

The reinsurance market is undergoing changes in the nature of its core business practices. One of the trends in the insurance industry has been the development of instruments designed to allow for the trading of insurance risks in the capital markets. Examples of insurance securitization tools that have been developed include catastrophe bonds and catastrophe equity puts. Trading insurance risks in the capital markets will spread the risks across alternative risk carriers which could lead to a reduced demand for reinsurance products.

We may face competitive disadvantages in the reinsurance industry

The reinsurance industry is highly competitive. Some of our competitors may have greater financial or operating resources or offer a broader range of products or more competitive pricing than we do. Our ability to compete is based on many factors, including our overall financial strength and rating, geographic scope of business, client relationships, premiums charged, contract terms and conditions, products and services offered, speed of claims payment, reputation, experience and qualifications of employees and local presence. We compete for reinsurance business in international reinsurance markets with numerous reinsurance and insurance companies, some of which have greater financial or other resources and some of which have higher financial strength ratings. We believe that our largest competitors include:

•

Munich Reinsurance Company;

•

Swiss Reinsurance Company;

•

Hannover Re Group;

•

SCOR;

•

PartnerRe Group; and

•

Lloyd’s syndicates active in the London market.

In addition, new companies have entered the reinsurance market and existing companies have raised additional capital to increase their underwriting capacity. Other financial institutions, such as banks, are also able to offer services similar to our own. We have also recently seen the creation of alternative products from capital market participants that are intended to compete with reinsurance products. We are unable to predict the extent to which these new, proposed or potential initiatives may affect the demand for our products or the supply and terms of risks that may be available for us to consider underwriting.

As a result of ongoing investigations of the insurance and reinsurance industry and non-traditional insurance products, we conducted an internal review and analysis of certain of our reinsurance transactions and have previously restated our financial statements, however the governmental inquiries are ongoing

Ongoing investigations of the insurance and reinsurance industry and non-traditional insurance and reinsurance products are being conducted by U.S. and international regulators and governmental authorities, including the U.S. Securities and Exchange Commission and the New York Attorney General.

On March 8, 2005, MBIA Inc. (“MBIA”) issued a press release stating that MBIA’s audit committee undertook an investigation to determine whether there was an oral agreement with MBIA under which MBIA would replace Axa Re Finance as a reinsurer to Converium Reinsurance (North America) Inc. (“CRNA”) by no later than October 2005. The press release stated that it appeared likely that MBIA made such an agreement or understanding with Axa Re Finance in 1998. Thereafter, on April 19, 2005, CRNA received subpoenas from the U.S. Securities and Exchange Commission and the Office of the New York Attorney General seeking documents related to certain transactions between CRNA and MBIA. Converium has also received additional inquiries from the Securities and Exchange Commission and other governmental authorities in Europe regarding non-traditional insurance and reinsurance products and/or the restatement of its financial statements. The inquiries are ongoing and Converium is fully cooperating with the governmental authorities.

In view of the industry investigations and the events relating to MBIA described above, Converium engaged independent outside counsel to assist it in a review and analysis of certain of its reinsurance transactions, including the MBIA transactions. The internal review, which was overseen by the Audit Committee, addressed issues arising from the ongoing governmental inquiries and Converium’s own decision to review certain additional items. The internal review involved the assessment of numerous assumed and ceded transactions including structured/finite risk and other reinsurance transactions and encompassed all business units of Converium, a review of hundreds of thousands of e-mails, attachments to e-mails and other documents and interviews of certain members of the Global Executive Committee and the Board of Directors, as well as certain former members of senior management and other employees of Converium. The Audit Committee believes that the scope and process of the internal review has been sufficient to determine whether Converium’s assumed and ceded transactions which improperly accounted for as reinsurance, rather than as deposits. After discussing the findings of Converium’s extensive internal review with independent outside counsel, the Audit Committee determined that certain accounting corrections were appropriate and authorized the restatement of Converium’s financial statements as of and for the years ended December 31, 2004 through 1998, which occurred during late 2005. As part of this process, the Audit Committee involved its independent group auditors, PricewaterhouseCoopers Ltd.

As noted above, we are fully cooperating with the governmental authorities, and are in the process of sharing the results of our internal review with the relevant authorities. Although the internal review was extensive, the ongoing governmental inquiries, or other developments, could result in further restatements of our financial results in the future and could have a materially adverse effect on Converium.

We are a defendant in a class action lawsuit related to the Company’s announcement on July 20, 2004 that second quarter 2004 results would fall short of expectations due to higher than modeled U.S. casualty loss emergence primarily related to the underwriting years 1996 to 2001

As discussed in greater detail below, the Company is a defendant in a securities law class action case arising out of the Company’s announcement on July 20, 2004 that second quarter 2004 results would fall short of expectations due to higher than modeled U.S. casualty loss emergence primarily related to the underwriting years 1996 to 2001. The consolidated actions are in the discovery phase; thus, the timing and outcome of these matters are not currently predictable. The costs of defending the class actions may have a material impact on our operating results in future reporting periods and an unfavorable outcome could have a materially adverse effect on the Company’s financial condition, results of operations and cash flows.

Regulatory or legal changes could adversely affect our business

Insurance laws, regulations and policies currently governing our clients and us may change at any time in ways which may adversely affect our business. Furthermore, we cannot predict the timing or form of any future regulatory initiatives. We are subject to applicable government regulation in each of the jurisdictions in which we conduct business, particularly in Switzerland, the United States, the United Kingdom and Germany. Regulatory agencies have broad administrative power over many aspects of the insurance and reinsurance industries. Government regulators are concerned primarily with the protection of policyholders rather than shareholders or creditors.

Recently, the insurance and reinsurance regulatory framework has been subject to increased scrutiny in many jurisdictions. Changes in current insurance regulation may include increased governmental involvement in the insurance industry, initiatives aimed at premium controls, requirements for participation in guaranty associations or other industry pools and other changes which could adversely affect the reinsurance business and economic environment. Such changes could impose new financial obligations on us, require us to make unplanned modifications of our products and services, or result in delays or cancellations of sales of our products and services.

The reinsurance industry is also affected by political, judicial, regulatory and other legal developments, which have at times in the past resulted in new or expanded theories of liability. We cannot predict the future impact of changing law or regulation on our business.

See “Item 4. — B. Business Overview — Regulation”.

European Reinsurance Directive may disadvantage companies like us which are not established within the European Union

The new EU Reinsurance Directive that was adopted on November 16, 2005 does not provide for any discrimination of non-EU based reinsurance companies. However, if the individual EU member states, in implementing the EU Reinsurance Directive, should include any discriminatory regulations with respect to reinsurers of a non-EU member state, this could be a disadvantage for Converium AG in its doing business in the EU, as Converium AG derives a substantial proportion of its revenues within the EU and any competitive disadvantage we face there could have an adverse effect on our financial condition, results of operations or cash flows. However, a large portion of those revenues are being written through our subsidiary in the EU member state Germany, where no negative impact can arise from the implementation of the directive. In addition Converium has a second subsidiary in the UK, which also is an EU member. See “Item 4. — Information on the Company — B. Business Overview — Regulation — European Union Directives”.

Our exposure to catastrophic events, both natural and man-made, may cause unexpected large losses

A catastrophic event or multiple catastrophic events may cause unexpected large losses and could have a material adverse effect on our business, financial condition, and results of operations or cash flows. Natural catastrophic events to which we are exposed include windstorms, hurricanes, earthquakes, tornadoes, severe hail, severe winter weather, floods and fires and man-made catastrophic events, for example, acts of terrorism, are inherently unpredictable in terms of both their occurrence and severity. For example, in 2005, the reinsurance industry suffered extensive losses from the hurricanes that occurred in the United States and the floods in Continental Europe. These events adversely affected our results.

We are also exposed to man-made catastrophic events, which may have a significant adverse impact on our industry and on us. It is possible that both the frequency and severity of man-made catastrophic events will increase.

As a result, claims from natural or man-made catastrophic events could cause substantial volatility in our financial results for any period and adversely affect our financial condition, results of operations or cash flows. Our ability to write new business could also be impacted. We believe that increases in the value and geographic concentration of insured property and the effects of inflation will increase the severity of claims from catastrophic events in the future.

The extent of our losses from catastrophic occurrences is a function of the frequency and severity of events, the number of our clients affected, and the total catastrophe losses incurred by our clients and our participation in the reinsurance policies affected. In addition, depending on the nature of the loss, the speed with which claims are made and settled, and the terms and conditions of the policies affected, we may be required to make large claims payments upon short notice. We may be forced to fund these obligations by liquidating investments unexpectedly and in unfavorable market conditions, or by raising funds at unfavorable costs, both of which could adversely affect the results of our operations.

Our efforts to protect ourselves against catastrophic losses, such as the use of selective underwriting practices, purchasing reinsurance (known as retrocessional reinsurance, when bought by a reinsurer such as Converium) and monitoring risk accumulation may not prevent such occurrences from adversely affecting our profitability or financial condition.

The majority of the natural catastrophe reinsurance we write relates to exposures within Europe, Japan and the United States. Accordingly, we are exposed to natural catastrophic events, which affect these regions, such as European windstorm, Japanese earthquake and US hurricane or earthquake events.

Terrorist attacks, national security threats, military initiatives and political unrest could result in the payment of material insurance claims and may have a negative effect on our business

Threats of terrorist attacks, national security threats, military initiatives and political unrest have had and may continue to have a significant adverse effect on general economic, market and political conditions, increasing many of the risks in our businesses. We cannot predict the long-term effects of terrorist attacks, threats to national security, military initiatives and political unrest on our businesses at this time.

Although Zurich Financial Services, through its subsidiaries, has agreed to arrangements that cap our exposure for losses and loss expenses arising out of the September 11th terrorist attacks at USD 289.2 (subsequently reduced to USD 231.0 million following the sale of our North American operations), net of retrocessional reinsurance recoveries, terrorist attacks and other man-made catastrophic events may have a material adverse effect on our business, financial condition or results of operations. For a discussion of the impact of the September 11th terrorist attacks on our business, see Note 8 to our 2006 consolidated financial statements.

If we are unable to achieve our investment objectives, our investment results may be adversely affected

Investment returns are an important part of our overall profitability, and fluctuations in the fixed income or equity markets could have a material adverse effect on our financial condition, results of operations or cash flows. For the years ended December 31, 2006 and 2005, net investment income and net realized capital gains accounted for 13.4% and 11.4% of our revenues, respectively. Our capital levels, ability to pay claims and our operating results substantially depend on our ability to achieve our investment objectives, which may be affected by general political and economic conditions that are beyond our control.

Fluctuations in interest rates affect our returns on fixed income investments in our available-for-sale portfolio, as well as the market values of, and corresponding levels of unrealized and realized capital gains or losses on the available-for-sale fixed income securities in our investment portfolio. Generally, investment income will be reduced during sustained periods of lower interest rates as higher yielding fixed income securities are called, mature or are sold and the proceeds reinvested at lower rates. During periods of rising interest rates, prices of fixed income securities tend to fall and realized gains upon their sale are reduced.

In addition, as described under “Formation transactions and relationship with Zurich Financial Services,” under the Quota Share Retrocession Agreement, the Funds Withheld Asset may be prepaid to us, in whole or in part, as of the end of any calendar quarter. In the event that the Funds Withheld Asset is prepaid, we would have to reinvest these assets in investments and we may not be able to invest them at yields comparable to those payable under the Quota Share Retrocession Agreement. To the extent we are not able to invest these funds at comparable yields, our investment income could be adversely affected.

Capital market fluctuations may adversely impact the value of our investments and shareholders’ equity

We had a cash and investments portfolio of USD 6,398.4 million as of December 31, 2006. As with any institutional investor with a similarly sized portfolio, Converium is exposed to the financial markets; in particular, an increase in interest rates, and a resulting decline in the market value of our fixed income securities, would adversely impact our shareholders’ equity for the securities we account for as available-for-sale.

General economic conditions can adversely affect the markets for interest-rate-sensitive securities, including the extent and timing of investor participation in such markets, the level and volatility of interest rates and, consequently, the value of fixed income securities. Interest rates are highly sensitive to many factors, including governmental monetary policies, domestic and international economic political conditions and other factors beyond our control.

We have historically invested and may continue to invest a portion of our assets globally in equity securities, which are generally subject to greater risks and more volatility than fixed income securities. General economic conditions, stock market conditions and many other factors beyond our control can adversely affect the equity markets and, consequently, the value of the equity securities we own.

Foreign exchange rate fluctuations may impact our financial condition, results of operation and cash flows

We publish our financial statements in US dollars. Therefore, fluctuations in exchange rates used to translate other currencies, particularly European currencies including the Euro, British pound and Swiss franc, into US dollars will impact our reported financial condition, results of operations and cash flows from year to year. These fluctuations in exchange rates will also impact the US dollar value of our investments and the return on our investments. For 2006, approximately:

•

80% of our net premiums written

•

60% of our net investment income

•

85% of our losses, loss expenses and life benefits, and

•

72% of our operating expenses

were denominated in currencies other than the US dollar. As we will only be writing limited business from the United States, a smaller proportion of our business will be denominated in US dollars in the future. For a discussion of the impact of material changes in foreign exchange rates on our shareholders’ equity, see “Item 11. — Quantitative and Qualitative Disclosures About Market Risks”.

The loss of key employees and executive officers without suitable replacements being recruited within a suitable period of time could adversely affect us

Our ability to execute our business strategy is dependent on our ability to attract, develop and retain a staff of qualified underwriters and other key employees. Our senior management team includes a number of key personnel whose skills, experience and knowledge of the reinsurance industry constitute important elements of Converium’s competitive strengths. If some of these executive officers or key employees leave their positions at Converium, even if we were able to find persons with suitable skills to replace them, our operations could be adversely affected. In addition, a strong financial position is important to us in order to retain and attract skilled personnel in the industry, especially underwriters with specific expertise in high-margin, non-commoditized specialty lines of business. If our current or future financial position does not allow us to do so, our operations could be adversely affected. See “Item 6. — Directors, Senior Management and Employees — A. Directors and Senior Management”.

Consolidation in the insurance industry could lead to lower margins for us and less demand for our reinsurance products and services

The insurance industry overall is undergoing a process of consolidation as industry participants seek to enhance their product and geographic reach, client base, operating efficiency and general market power through merger and acquisition activities. These larger entities may seek to use the benefits of consolidation to, among other things, implement price reductions for the products and services they purchase. If competitive pressures compel us to reduce our prices, our operating margins would decrease.

As the insurance industry consolidates, competition for customers may become more intense and the importance of acquiring and properly servicing each customer will become greater. We could incur greater expenses relating to customer acquisition and retention, which could reduce our operating margins. In addition, insurance companies that merge may be able to enhance their negotiating position when buying reinsurance and may be able to spread their risks across a larger capital base so that they require less reinsurance.

We purchase retrocessional reinsurance, which may become unavailable on acceptable terms and subjects us to credit risk

In order to limit the effect on our financial condition of large and multiple losses, we buy retrocessional reinsurance. From time to time, market conditions have limited, and in some cases have prevented, insurers and reinsurers from obtaining the types and amounts of reinsurance which they consider adequate for their business needs. There can be no assurance that we will be able to obtain our desired amounts of retrocessional reinsurance. There is also no assurance that, if we are able to obtain such retrocessional reinsurance, we will be able to negotiate terms as favorable to us as in prior years.

A retrocessionaire’s insolvency or its inability or unwillingness to make payments under the terms of its reinsurance treaty with us could have a material adverse effect on our business, financial condition, results of operations or cash flows. Therefore, our retrocessions subject us to credit risk because the ceding of risk to retrocessionaires does not relieve us of our liability to our ceding companies.

We are dependent on a small number of reinsurance brokers for a large portion of our revenue and exposed to their credit risk

We market our reinsurance products in our target markets in part through reinsurance brokers. In some markets we principally write through reinsurance brokers. Loss of all or a substantial portion of the business written through brokers could have a material adverse effect on our financial condition, results of operations or cash flows.

Although the percentage of our gross premiums written produced through brokers decreased to 28% in 2006 (from 32% in 2005), we are still subject to risks associated with business produced through brokers. In accordance with industry practice, we frequently pay amounts owed on claims under our policies to reinsurance brokers, and these brokers, in turn, pay these amounts over to the insurers that have reinsured a portion of their liabilities with us. We refer to these insurers as ceding insurers. In some jurisdictions, or pursuant to some contractual arrangements, if a broker fails to make such a payment, we may remain liable to the ceding insurer for the deficiency. Conversely, in certain jurisdictions, when the ceding insurer pays premiums for these policies to reinsurance brokers for payment over to us, these premiums are considered to have been paid and the ceding insurer will no longer be liable to us for those amounts, whether or not we have actually received the premiums. Consequently, in connection with the settlement of reinsurance balances, we assume a degree of credit risk associated with reinsurance brokers around the world.

We may be adversely affected if Zurich Financial Services or its subsidiaries fail to honor their obligations to us or our clients

As part of the Formation Transactions described under “Formation transactions and relationship with Zurich Financial Services” in “Item 4. — Information on the Company — A. History and Development of the Company” and in “Item 10. — Additional Information — C. Material Contracts”, we entered into a number of contractual agreements with Zurich Financial Services and its affiliates including the Master Agreement, the Quota Share Retrocession Agreement, the Master Novation and Indemnity Reinsurance Agreement, service agreements, lease agreements and certain indemnity agreements. Among other things, under the Quota Share Retrocession Agreement, Zurich Financial Services, through its subsidiaries, provides us with a substantial amount of our investment returns. Additionally, Zurich Financial Services, through its subsidiaries, has agreed to arrangements that cap our exposure, net of retrocessional reinsurance recoveries, for losses and loss expenses arising out of the September 11th terrorist attacks at USD 289.2 million, (subsequently reduced to USD 231.0 million following the sale of our North American operations) the amount of loss and loss expenses we recorded as of September 30, 2001. In addition, subsidiaries of Zurich Financial Services have provided us with retrocessional reinsurance protection, provided coverage for certain workers’ compensation exposure, indemnified us for specified taxes and other matters and agreed to lease or sublease office space to us. Therefore, we are exposed to credit risk from Zurich Financial Services with respect to these obligations.

In addition, Zurich Financial Services subsidiaries remain the legal counterparty for many of our assumed reinsurance contracts, particularly those reinsurance contracts entered into prior to the date of the initial public offering. Although we do not have credit risk exposure with respect to these contracts, if these Zurich Financial Services subsidiaries do not honor their commitments efficiently and effectively to these clients, we might bear reputational risk. See “Item 4. – Information on the Company – A. History and Development of the Company”.

We are dependent on a small number of relationships for a substantial proportion of our business; the loss of a key business relationship could significantly reduce our premium volume and reduce net income

Substantial parts of our current business come from a small number of relationships such as Lloyd’s syndicates, MDU and GAUM which represent approximately 38% of our total gross premiums written. We are therefore exposed to certain concentration risk. The loss of all or a substantial portion of a key business relationship could significantly reduce the gross premium written and net income of a business segment or the company overall.

We may be restricted from consummating a change of control transaction, disposing of assets or entering new lines of business

Certain tax considerations and contractual arrangements with Zurich Financial Services may make an acquisition of Converium less likely and limit our ability to dispose of assets or enter into new lines of business. See “Formation transactions and relationship with Zurich Financial Services”.

Our inability to dispose of assets or enter new lines of business may render us less able to respond to changing market and competitive conditions, which could have a material adverse effect on our financial condition, results of operations or cash flows.

We are potentially exposed to a significant loss of business in the event of a change of control

Certain business that we write contains termination provisions which give the ceding company or counterparty the right of termination in the event of a change in control. Whether a change in control has taken place will ordinarily be determined by the legal jurisdiction which governs the individual contract concerned.

The Company has a number of material contracts which contain such a clause including the aviation pool membership and shareholders agreement in GAUM, the MDU business and our shareholding in MDUSL and the ZIC and ZIB Quota Share Retrocession Agreements. Accordingly the exercise of termination provisions following a change in control could have a material adverse impact on our business, operating results and financial condition.

We may require additional equity or debt financing in the future, which may only be available at unfavourable terms

Our future capital requirements depend on many factors, including our ability to write new business successfully, the frequency and severity of catastrophic events, and our ability to establish premium rates and reserves at levels sufficient to cover losses.

We may need to raise additional funds through financings or curtail our growth and reduce our assets. Any equity or debt financing, if available at all, may be on terms that are not favourable to us.

Equity financings could be dilutive to our existing shareholders and could result in the issuance of securities that have rights, preferences and privileges that are senior to those of our other securities. If we cannot obtain adequate capital on favourable terms or at all, our business, operating results and financial condition could be adversely affected.

Risks Related to SCOR’s Tender Offer for Converium’s registered shares

On May 9, 2007, Converium and SCOR entered into a transaction agreement (the “SCOR Transaction Agreement”) pursuant to which SCOR agreed to offer holders of Converium’s registered shares 0.5 new SCOR shares and CHF 5.50 in cash in exchange for each Converium registered share tendered and Converium agreed that its Board of Directors would recommend SCOR’s Tender Offer (the "SCOR Tender Offer") to Converium shareholders. We are subject to the following risks as a result of the SCOR Tender Offer:

Regardless of whether or not the SCOR Tender Offer is completed, the announcement and pendency of the SCOR Tender Offer could cause disruptions in our business

Uncertainty about the effect of the SCOR Tender Offer on our business operations and employees could result in a material adverse effect on our financial condition and operating results. These uncertainties may impair our ability to retain and motivate key personnel until the SCOR Tender Offer is completed and could cause our customers and other parties who deal with us to defer decisions regarding business relationships with us or other decisions concerning us, or to seek to change existing business relationships with us. If key employees depart because of uncertainty about their future roles with us, our ability to continue to execute our business and strategic plans could be adversely affected. In addition, the attention of our management may shift away from our ongoing business toward the completion of the SCOR Tender Offer and the integration of our businesses following the consummation of the SCOR Tender Offer. If the SCOR Tender Offer is not completed, our management will have spent considerable time, and incurred significant expenses, which could adversely affect our business and results of operations. Converium expects significant transaction and defense services costs during 2007. In addition, the loss of employees, customers or other relationships during the pendency of the SCOR Tender Offer could adversely affect our business if the SCOR Tender Offer is not completed. Furthermore, the SCOR Transaction Agreement generally restricts us, until the SCOR Tender Offer occurs, from taking actions outside of the ordinary course of business, without the consent of SCOR. These restrictions could adversely affect our ability to pursue key aspects of our strategic plans prior to the completion of the SCOR Tender Offer.

If SCOR is unsuccessful and the SCOR Tender Offer is not consummated, SCOR will control a substantial portion of our registered shares

If the SCOR Tender Offer is not consummated, SCOR will control approximately 32.9% of our voting securities. As a result, SCOR may over time be able to remove our current directors and elect a slate of its own directors and otherwise exert significant influence over the day-to-day affairs of the Company.

After completion of the SCOR Tender Offer, there may be substantial difficulty and costs associated with the integration of our operations with those of SCOR’s

Prior to the completion of the SCOR Tender Offer, the Company and SCOR operated, and will continue to operate, as independent companies, each with its own business, products, customers, employees, culture and systems. As such, the integration process will be complex, time-consuming and expensive and we may face substantial difficulties, costs and delays associated with the integration, including:

• perceived adverse changes in product offerings available to clients or client service standards, whether or not these changes do, in fact, occur;

• the retention of our and SCOR’s existing clients, joint venture partners and underwriters; and

• retaining and integrating management, underwriters and other key employees of the resulting company.

After the consummation of the SCOR Tender Offer, the combined company may seek to consolidate certain operations and functions using common information and communication systems, operating procedures, financial controls and human resource practices, including training, professional development and benefit programs. The combined company may be unsuccessful or delayed in implementing the integration of these systems and processes and, as a result, the expected benefits of a transaction with SCOR may be delayed. Furthermore, as discussed below, following the consummation of the SCOR Tender Offer, Inga Beale, our Chief Executive Officer, and Paolo De Martin, our Chief Financial Officer, will be terminated with effect as of December 31, 2007.

We entered into the SCOR Transaction Agreement with the expectation that the combination with SCOR could result in various benefits including, among other things, benefits relating to enhanced revenues, a strengthened market position for the resulting company in its businesses, cross-selling opportunities, cost savings and operating efficiencies. Achieving the anticipated benefits is subject to general competitive factors in the marketplace and a number of uncertainties, including our ability to integrate with SCOR in an efficient and effective manner. Any delay or the failure to achieve these anticipated benefits could result in increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy and could materially impact the resulting company’s business, financial condition and operating results.

While we have no intention of doing so, the SCOR Transaction Agreement limits our ability to pursue alternatives to the SCOR Tender Offer

Under the terms of the SCOR Transaction Agreement, we are generally precluded from encouraging or participating in any discussions that could lead to an alternative transaction to the current transaction with SCOR. Similarly, subject to certain exceptions, our Board of Directors is restricted in its ability to withdraw or modify its recommendation that our stockholders approve the SCOR Tender Offer.

The consideration offered in the SCOR Tender Offer is substantially share based which, if taken up by shareholders, would expose them to any future SCOR share price fluctuations

The consideration offered in the SCOR Tender Offer is substantially share based which, if taken up by shareholders, would expose them to any future SCOR share price fluctuations. In addition, our review of SCOR’s business was limited to publicly available information. Consequently, we have not independently verified the public information available to us and any undisclosed or unknown liabilities of SCOR may have an adverse affect on the benefits of the combination or on SCOR’s profitability, results of operations, financial condition or prospects following the combination.

The market for the Company’s registered shares and ADSs may be less liquid following completion of the SCOR Tender Offer, and the value of registered shares and American Depository Shares may be lower

The consummation of the SCOR Tender Offer will reduce the number of holders of Converium registered shares as well as the number of Converium registered shares that might otherwise trade publicly and, depending upon the number of Converium registered shares so exchanged, could adversely affect the liquidity and market value of the remaining Converium registered shares and American Depositary Shares held by the public. The extent of the public market for the Converium registered shares and the availability of such quotations would depend upon such factors as the number of holders remaining at such time, the interest on the part of securities firms in maintaining a market in Converium registered shares or Converium American Depositary Shares, and the possible termination of registration of Converium registered shares and American Depositary Shares under the Exchange Act, would adversely affect the amount of publicly available information with respect to Converium.

The SCOR Tender Offer has not been extended in, or into, the United States or to holders of the Company’s American Depositary Shares

Because the SCOR Tender Offer has not been extended to holders of our registered shares in the United States and is not extended to holders of the Company’s American Depositary Shares, regardless of whether such American Depositary Shares are held by persons outside of the United States, to the extent you are a U.S. resident or hold American Depositary Shares, you may not participate in the SCOR Tender Offer. In that instance, following the consummation of the SCOR Tender Offer, you may hold shares or American Depositary Receipts in a Company controlled by SCOR.

The failure of SCOR to consummate the SCOR Tender Offer could negatively affect the price of our registered shares and American Depositary Shares and our future business and financial prospects.

There is no assurance that SCOR will successfully complete the SCOR Tender Offer. If the SCOR Tender Offer is not completed, our management will have spent considerable time, and incurred significant expenses, which could adversely affect our business and results of operations. Our management has spent, and will continue to spend, considerable amounts of time focusing on the integration of our businesses, which could limit their time and effort available to pursue other business activities that may be important to our operations. Additionally, the market price of our registered shares and American Depositary Shares may reflect a market assumption that the SCOR Tender Offer is likely to be consummated, and a failure to do so would likely result in a decline in the market price of our registered shares and American Depositary Shares.

ITEM 4. INFORMATION ON THE COMPANY

Converium Holding AG was incorporated in Switzerland on June 19, 2001 as a joint stock company as defined in article 620 et seq. of the Swiss Code of Obligations. We were registered on June 21, 2001 in the Commercial Register of the Canton of Zug with registered number CH-170.3.024.827-8. Our registered office is General Guisan-Quai 26, CH-8002 Zürich, Switzerland and our telephone number is +41 44 639 9335.

A. HISTORY AND DEVELOPMENT OF THE COMPANY

On March 22, 2001, Zurich Financial Services announced its intention to divest substantially all of its third-party reinsurance business historically operated under the “Zurich Re” brand name. This business had been managed and operated as a global operation since 1998. We refer to our initial public offering and the associated transactions described below in this Form 20-F as the “Formation Transactions”. As part of the Formation Transactions, ownership of this business was consolidated under Converium Holding AG, a newly incorporated Swiss company.

The Formation Transactions consisted of the following principal steps:

•

The transfer to us of the “Zurich Re” reinsurance business now conducted by Converium AG, through a series of steps including:

	o		Our reinsurance of this business through quota share retrocession agreements with two units of Zurich Financial Services, (the “Quota Share Retrocession Agreement”);

	o		The establishment of “funds withheld” balances in our favor by the applicable units of Zurich Financial Services (the “Funds Withheld Asset”), on which we will be paid investment returns by the Zurich Financial Services units;

	o		The transfer of assets including cash, marketable securities and participations by Zurich Financial Services and its subsidiaries to Converium, together with the assumption of liabilities;

•		The acquisition of the Cologne reinsurance business through the transfer by a subsidiary of Zurich Financial Services to Converium AG of its 98.63% interest in ZRK, which was renamed Converium Rückversicherung (Deutschland) AG. Converium’s interest in Converium Rückversicherung (Deutschland) AG increased to 100% in January 2003;

•		The acquisition of the North American reinsurance business through the transfer by a subsidiary of Zurich Financial Services of all of the voting securities of Zurich Reinsurance (North America) Inc. to CHNA Inc., a wholly owned subsidiary of Converium AG. In conjunction with this transfer, CHNA assumed USD 200 million of public debt from a subsidiary of Zurich Financial Services, and Zurich Reinsurance (North America), Inc. was renamed CRNA;

•		The sale of 35,000,000 of our registered shares to the public by Zurich Financial Services on December 11, 2001 in our initial public offering and the subsequent sale of 5,000,000 of our registered shares to the public by Zurich Financial Services on January 9, 2002 as a result of the underwriters’ exercise of their over-allotment option, which sales resulted in the public owning 100% of our shares; and

•		After our initial public offering, Converium AG used cash transferred to us by Zurich Financial Services to acquire from subsidiaries of Zurich Financial Services approximately USD 140 million of residential and commercial rental properties located in Switzerland.

As part of the Formation Transactions, Zurich Financial Services and its subsidiaries transferred cash and other assets and liabilities to Converium. The assets transferred to us included:

•		The shareholders’ equity of the legal entities comprising our operating businesses;

•		The operating assets of the Zurich reinsurance business; and

•		The balance of the assets transferred to us consisted of investments and cash, of which approximately USD 140 million was used by Converium AG to acquire residential and commercial rental properties located in Switzerland from subsidiaries of Zurich Financial Services

For a description of the agreements and transactions involved in the Formation Transactions and our divestiture from Zurich Financial Services, including certain ongoing contractual arrangements with Zurich Financial Services, see “Item 10. — Additional Information — C. Material Contracts”.

For description of our capital raising activities that occurred in October 2004, see “Item 10. — Additional Information — B. Memorandum and Articles of Incorporation”.

Converium PCC Ltd, Guernsey, is a company incorporated for an unlimited time in Guernsey/United Kingdom on October 31, 2000, which was set up in conjunction with the Formation Transactions of the IPO. The company holds a reinsurance license from the Guernsey Financial Services Commission dated October 12, 2001, and its purpose is to facilitate the intra-group reinsurance between certain branch offices of Converium AG and the parent.

In 2004, we formed Converium Finance (Bermuda) Ltd, as well as Converium IP Management Ltd, both of which were incorporated in Bermuda on December 17, 2004. As part of the formation process, Converium Holding AG contributed the rights to commercially exploit the Converium brand to Converium Finance (Bermuda) Ltd, which in turn sold the rights to commercially exploit the Converium brand in exchange for a loan to Converium IP Management Ltd. Converium IP Management AG, Bermuda, entered into a license agreement allowing it to commercially exploit the Converium brand with respect to our operating insurance respectively, reinsurance branch offices and subsidiaries. We implemented this corporate change mainly to comply with relevant tax rules applicable to holding companies in the Canton of Zug, Switzerland in order to protect the current tax status of Converium Holding AG as a holding company. During 2005, we subsequently transferred the domicile of Converium IP Management Ltd to Zug, Switzerland.

On December 13, 2006, Converium sold its US operations including CRNA and Converium Insurance (North America) Inc. (“CINA”) to National Indemnity Company, a Berkshire Hathaway company for a total consideration of USD 295.0 million comprising of USD 95.0 million in cash and USD 200.0 million in assumption of debt. Converium has not provided any guarantee or indemnity in respect of the reserves of the North American operations. The transaction was approved by the Insurance Department of the State of Connecticut.

On Monday, February 19, 2007, SCOR publicly announced that it had acquired a 32.9% interest in Converium’s outstanding registered shares, of which 8.3% and 24.6% were acquired through direct market purchases and share purchase agreements, respectively. On Monday, February 26, 2007, SCOR issued a pre-announcement of the then unsolicited tender offer for Converium’s registered shares (as defined below) in accordance with the laws of Switzerland.

On April 5, 2007, SCOR formally launched an unsolicited tender offer pursuant to which each of Converium’s registered share were to be exchanged for 0.5 ordinary shares of SCOR and CHF 4, the cash portion of which was to be reduced by the gross amount of any dilutive effects in respect of Converium’s registered shares prior to the consummation of the SCOR Tender Offer. On May 9, 2007, Converium and SCOR entered into the SCOR Transaction Agreement pursuant to which SCOR agreed to offer holders of Converium’s registered shares 0.5 new SCOR shares and CHF 5.50 in cash in exchange for each Converium registered share tendered and Converium agreed that its Board of Directors would recommend the SCOR Tender Offer to Converium shareholders. SCOR has further agreed to not to reduce the cash portion of the offer consideration by the Company’s gross dividend of 0.20 CHF per share for the fiscal year ended December 31, 2006. The SCOR Tender Offer is governed by the laws of Switzerland and is extended to all holders of the Company’s registered shares located outside of the United States and Japan and is not extended to holders of the Company’s American Depositary Shares, regardless of whether such American Depositary Shares are held by persons outside of the United States or Japan. The SCOR Tender Offer commenced on June 12, 2007 and will remain open for acceptances for a period of 20 business days.

financial results, the Corporate Center carries certain administration expenses, such as costs of the Board of Directors, the Global Executive Committee and other corporate functions as well as expenses not allocated to the operating segments. The business segments are supported by global business support functions such as Actuarial & Risk Management Services, and by global services such as Human Resources, Finance and IT. We believe that this structure provides a higher degree of transparency, accountability and management control. In addition to reporting segment results individually, management also aggregates results for Standard Property & Casualty Reinsurance and Specialty Lines into non-life business, as management considers this aggregation meaningful in understanding the performance of Converium.

We offer a broad range of non-life and life reinsurance products. In non-life reinsurance, our lines of business include General Third Party Liability, Motor, Personal Accident (assumed from non-life insurers), Property, Agribusiness, Aviation & Space, Credit & Surety, Engineering, Marine & Energy, Professional Liability and other Special Liability and Workers’ Compensation. In Life & Health Reinsurance, our lines of business include Life and Disability reinsurance, including quota share, surplus coverage and financing contracts and Accident & Health.

In addition to our offices in Cologne, Zug and Zurich, we have branch offices in Bermuda, Labuan, Milan, Paris, Singapore, Sydney as well as marketing offices in Buenos Aires, Sao Paulo and Tokyo and Kuala Lumpur. We have a sub-holding company in London and finance subsidiaries in Luxembourg and Bermuda, an IP company in Zug, Switzerland and a licensed reinsurance company in Guernsey, United Kingdom, facilitating intra-group reinsurance within Converium.

We underwrite reinsurance both directly with ceding companies and through intermediaries, giving us the flexibility to pursue business in accordance with our ceding companies’ preferred reinsurance purchasing method. In addition, we generate business through strategic partnerships and joint ventures such as GAUM and MDU. In 2006, 28% of our gross premiums written were written through intermediaries and 72% of our business was written on a direct basis.

Our vision

We aim to be a major player in the international reinsurance industry. Our efforts are focused on supporting our clients with leading-edge solutions. We aspire to be recognized as a learning, decisive, communicative and action-oriented organization.

Our mission

We are an international multi-line reinsurer that satisfies our clients’ needs by excelling at analyzing, assuming and managing risks. We are experts in managing our clients’ volatility and helping them optimize capital efficiency. In an ethical and responsible manner we provide:

•		sustainable value growth for our shareholders;

•		excellent service for our customers and intermediaries; and

•		a fulfilling work environment for our employees.

Our strategy

–

Making investments in specialty lines: Based on the Company’s track record and human capital Converium is committed to further expanding its specialty portfolio, including aviation & space, engineering, marine & energy, credit & surety and agribusiness.

–

Further enhancing the risk management and control culture: These efforts will focus on further implementing a state-of-the-art Enterprise Risk Management (ERM) framework.

–

Advancing cost and capital efficiency: Converium is committed to further rationalise its internal processes and setup in order to achieve a competitive administrative expense ratio. In addition, Converium constantly seeks to maximize capital efficiency by exploring opportunities for leveraging its balance sheet and transferring risks directly to capital markets.

Our core business

Our core business is to analyze, assume and manage portfolios of insurance risks, and to invest our assets so that they support the insurance risks we assume. Our strategy for each of our business segments is as follows:

Standard Property & Casualty Reinsurance

The Standard Property & Casualty Reinsurance segment is comprised of the General Third Party Liability, Motor, Personal Accident (assumed from non-life insurers) and Property lines of business. The segment strategy focuses on partnership-oriented professional reinsurance buyers in the markets Europe, Latin America and Asia. Our long-term client relationships are based on our capabilities, e.g. natural hazard expertise, financial modeling capabilities, structuring advice and claims and underwriting audits, contributing to earnings and cash flows. We remain committed to underwriting discipline to achieve the best possible shareholder return, which is only possible through cycle management.

Specialty Lines

The Specialty Lines segment includes the Agribusiness, Aviation & Space, Credit & Surety, Engineering, Marine & Energy, Professional Liability and other Specialty Liability and Workers’ Compensation lines of business. The Specialty Lines segment’s strategy is to develop specialty businesses in which Converium can position itself as a market leader and effectively leverage its intellectual assets in risk analysis, structuring, product design and risk modeling. We focus on specialty businesses because we believe that Converium possesses superior underwriting and structuring capabilities in certain areas, which is both a key driver of profitability as well as an effective barrier to entry in certain business lines.

them from having to compete in annual insurance or reinsurance auctions. Examples of the approach by which we seek to develop preferred access to these businesses are our strategic partnership with MDU in the U.K. and our participation in GAUM and our shares in its pools, as well as many strong relationships with specialized mono-line insurers.

Also, Converium Underwriting Ltd, a Lloyd’s Corporate Member, has successfully provided and continues to provide third-party capacity to certain specialist Lloyd’s syndicates.

Some specialty lines are subject to cyclical pricing fluctuations. Converium remains committed to underwriting discipline to achieve the best possible shareholder return, which is only possible through cycle management.

Life & Health Reinsurance

The Life & Health Reinsurance segment comprises the Life & Disability and Accident & Health lines of business. The Life & Health Reinsurance segment’s strategy is to increase the stability of Converium’s income. Traditional life reinsurance has a low correlation to property and casualty risks and can therefore improve our risk diversification. Our Life & Health Reinsurance segment will continue to grow its activities in its existing key markets, which are Germany, Italy and France; markets with significant potential for future opportunities for us include Denmark and the Netherlands.

The business segments are supported by global business support functions such as Actuarial & Risk Management Services, and by global services such as Human Resources, Finance and IT.

Guiding principles for our business

We have established the following guiding principles for the development of our business:

•		Our lead objective is to maximize economic value. The metrics we use to measure this are pre-tax operating income and “performance excess”. “Performance excess” is the measure we use to implement economic value-based management at Converium and is an internal key metric for measuring expected and actual underwriting performance. “Performance excess” represents the economic value added attached to all reinsurance contracts in our portfolio and takes into account all expected benefits and costs emanating from a contract or group of contracts, including expected premiums, expected losses and all other internal and external costs including taxes and the costs of the allocated risk-based capital. Hence, “performance excess” equals the expected net present value created for shareholders, in excess of the cost of capital;

•		To optimize our overall risk profile, we balance and diversify our portfolio by line of business, by region and by duration;

•		All contracts we underwrite should be profitable in expectation; that is, a “performance excess” target of at least equal to zero.

•		We seek to grow our business, but sustainable profitability is a prerequisite; and

•		Assumed London market retrocession, financial guarantees and underwriting authorities for assumed reinsurance are outside of our strategic scope.

In addition, we have established the following guiding principles to manage our business:

Cycle management. We have a systematic approach to the allocation of capital and resources to those lines of business and markets that meet our profitability standards, and to withdraw from business that does meet our performance thresholds. Historically, the reinsurance cycles in different lines of business and markets have not moved simultaneously. Our strong international franchise and our distribution and servicing platform provide broad access to an international reinsurance market, and enable the flexible allocation of resources to those lines of business or markets in which profitability prospects are most favorable at any point in time. Our well established relationships with clients and intermediaries, as well as our transparent pricing approach, allow us to manage the cycle by moving in and out of lines of business or markets without putting long-term business relationships at risk.

Risk management. The prominence of risk within Converium, together with its inclusive implementation, has further strengthened the Company’s Enterprise Risk Management (ERM) practices. This approach is based on five pillars: Risk Management Culture, Risk Controls, Emerging Risk Management, Risk and Capital Models, and Strategic Risk Management. ERM was designated as a distinct rating category by Standard & Poor’s (together with other rating agencies) in 2006. It is designed to focus financial institutions on

taking a comprehensive view of their entire risk landscape, and gain a holistic approach to risk measurement, rather than having potential exposures in distinct risk areas.

Operational excellence. We manage our expense base effectively through continuous analysis of business processes and operational structures, with a view to enhancing business integration and achieving synergies and efficiencies.

Retention management. We manage our gross and net risk positions on a group-wide basis, through global risk pooling and the use of retrocession on specific line of business exposures.

Investment policy. We allocate capital primarily to support underwriting risks with the aim of optimizing the after-tax risk-return characteristics of our investment portfolio. The recently hired global asset manager assumed overall responsibility for the management of our fixed income portfolio. In order to achieve a higher yielding diversification we adopt a less defensive and more sophisticated approach towards managing this asset class, which is by far the single largest class in Converium’s investment portfolio. A shift of our assets into less constrained portfolios supports the optimization of investment yield. Nevertheless, our asset allocation continues to focus on a core portfolio of high quality bonds supplemented by complementary portfolios in other asset classes, including equities, real estate and non traditional or alternative investments.

Capital management. Our main capital management objectives focus on:

–		a disciplined approach based on our state of the art Enterprise Risk Management (ERM) approach, with excess capital being deployed for profitable growth and being returned to shareholders;

–		an optimized and appropriately leveraged balance sheet;

–		a consistent dividend policy with a proposed sustainable pay-out ratio of 25-35%.

Premium accruals are impacted if and when cedents report premium adjustments over time as the underlying exposure becomes increasingly certain. The premium impact is positive, i.e., accruals increase, if the cedent has assumed a higher exposure and hence higher premium than expected at policy inception. It is typically negative if estimated premiums for the assumed exposure turn out to be lower, leading to a reduction in accruals. The process of adjusting premium accruals varies greatly because cedents in many countries around the world apply local practices for, among other things, the recording of exposure, financial reporting as well as reporting to third parties (such as their reinsurers) and the timing of recording final premiums. In addition, accruals can be impacted by contracts cancelled under special termination clauses, leading to a reduction in premium accruals.

Acquisition costs are comprised of different components, of which some are recognized in line with premiums, as opposed to others which are recognized on different bases such as the profitability of each underlying treaty.

Types of reinsurance

Both non-life reinsurance and life reinsurance can be written on either a proportional basis or a non-proportional basis. Proportional reinsurance is also known as pro rata reinsurance. Quota share reinsurance and surplus reinsurance are types of proportional reinsurance. Some non-proportional reinsurance takes the form of excess of loss reinsurance in which the reinsurer’s obligations are only triggered after covered losses exceed a specified attachment point. In the case of proportional reinsurance, the reinsurer assumes a predetermined portion of the ceding company’s risks under the covered insurance contract or contracts. In the case of non-proportional reinsurance, the reinsurer assumes all or a specified portion of the ceding company’s risks in excess of a specified amount, known as the ceding company’s retention or the reinsurer’s attachment point, subject to a negotiated reinsurance contract limit.

Premiums that the ceding company pays to a reinsurer for proportional reinsurance are a predetermined portion of the premiums that the ceding company receives from its insured, consistent with the proportional sharing of risk. In addition, in proportional reinsurance, the reinsurer generally pays the ceding company a ceding commission. The ceding commission is usually based on the ceding company’s cost of generating the business being reinsured, which includes commissions, premium taxes, assessments and miscellaneous administrative expenses and a profit participation for originating the business, the amount of which is based on the claims experience. The ceding commission may also be affected by competitive factors. Premiums that the ceding company pays to a reinsurer for non-proportional reinsurance are not directly proportional to the premiums that the ceding company receives because the reinsurer does not assume a direct proportion of the ceding company’s risk. The frequency of claims under a proportional reinsurance contract is usually greater than under a non-proportional contract, and therefore the claims experience with proportional reinsurance contracts is generally more predictable.

Non-proportional non-life reinsurance is often written in layers. One or a group of reinsurers accepts the risk just above the ceding company’s retention up to a specified amount, at which point another reinsurer or a group of reinsurers accepts the excess liability up to an additional specified limit or the excess liability reverts to the ceding company. The reinsurer taking on the risk just above the ceding company’s retention is typically said to write lower layer excess reinsurance. A claim that reaches just beyond the ceding company’s retention will create a claims payment for the lower layer reinsurer, but not for the reinsurers of any higher layers. Claims activity in lower layer reinsurance tends to be more predictable than in higher layers due to greater frequency and availability of historical data, and therefore, like proportional reinsurance, better enables underwriters and actuaries to more accurately price the underlying risks. In a limited number of cases, reinsurance is also written on an aggregate stop-loss basis to protect the ceding company’s total portfolio from extraordinary losses resulting from the aggregation of individual risks.

Both non-life reinsurance and life reinsurance can be written either through treaty or facultative reinsurance arrangements. In treaty reinsurance, the ceding company cedes, and the reinsurer assumes, a specified portion of a type or category of risks insured by the ceding company. Generally in the industry, treaty reinsurers do not separately evaluate each of the individual risks assumed under their treaties and are largely dependent on the original risk underwriting decisions made by the ceding company’s underwriters. This dependence subjects reinsurers to the possibility that the ceding company has not adequately evaluated the risks to be reinsured and, therefore, that the premiums ceded to the reinsurer may not adequately compensate the reinsurer for the risk assumed. Accordingly, the reinsurer’s evaluation of the ceding company’s risk management and underwriting practices, as well as claims settlement practices and procedures, will usually impact the pricing of the treaty.

In facultative reinsurance, the ceding company cedes, and the reinsurer assumes, all or part of a specific risk or risks. Facultative reinsurance normally is purchased by ceding companies for risks not covered by their reinsurance treaties, for amounts in excess of the monetary limits of their reinsurance treaties and for unusual and complex risks. In addition, facultative risks often provide coverages for relatively severe exposures, which results in greater volatility. The ability to evaluate separately each risk reinsured, however, increases the probability that the reinsurance underwriter can price the contract to reflect more accurately the risks involved.

Non-traditional reinsurance involves structured reinsurance solutions tailored to meet individual client strategic and financial objectives. Both non-life reinsurance and life reinsurance can be written on a structured/finite basis. Often these reinsurance solutions provide reinsurance protection across a company’s entire insurance portfolio. Because of the constantly changing industry and regulatory framework, as well as the changing market demands facing insurance companies, the approaches utilized in structured/finite programs are constantly evolving and will continue to do so.

We underwrite our product lines on a non-proportional and proportional basis. We integrate our facultative specialists with our underwriting professionals with treaty expertise, organizing them as focused teams around client relationship management and lines of business. We do not distinguish between treaty and facultative reinsurance, but rather between proportional and non-proportional underwriting and lines of business.

Proportional and non-proportional

We offer traditional reinsurance products on both a proportional and non-proportional basis in all our lines of business. Our business is predominantly proportional, comprising approximately 85.7% of gross premiums written during 2006. Our non-proportional business includes Property, Motor, Aviation & Space and Professional Liability and other Special Liability lines, to complement our established market position in non-proportional liability.

We believe that clients and brokers actively seek our input in the evaluation and structuring of businesses with unique or difficult risk characteristics. We believe this is a result of our innovative approach, organizational resources and financial condition. We have developed integrated teams of professionals with significant treaty and individual risk, or facultative, expertise which support the professionals we have in our branch network. We offer facultative products to a limited extent and only to a selected number of clients on a proportional and non-proportional basis. We deploy our international specialty lines experts and local specialists to design solutions to address our clients’ risk management needs.

Structured/finite

Structured/finite reinsurance business is contained within our Standard Property & Casualty Reinsurance, Specialty Lines and Life & Health Reinsurance segments. Whether working directly with the client or through a broker, our structured/finite business focuses on developing client-specific solutions after spending time with the client to understand its business needs. These client-specific solutions include such products as loss portfolio transfers and adverse loss development covers. Loss portfolio transfers involve the transfer of liability of discontinued or expired insurance programs from one company to another company for a fee. Coverage under adverse development covers is provided on an excess basis and amounts of indemnification are generally subject to specific aggregate limits.

Structured/finite products have several features that differ from traditional reinsurance products and may typically include (i) premium refunds based on actual loss experience; (ii) loss sharing provisions; (iii) additional premiums based on actual loss experience, (iv) sliding scale commission rates, (v) non-refundable reinsurer’s margins; and (vi) underwriting terms that limit the maximum aggregate exposure. Structured/finite business is classified as proportional or non-proportional, depending on its characteristics.

Standard Property & Casualty Reinsurance

The Standard Property & Casualty Reinsurance segment’s strategy focuses on partnership-oriented professional reinsurance buyers in the markets Europe, Latin and South America and Asia. Our long-term client relationships are based on our capabilities, e.g. natural hazard expertise, financial modeling capabilities, structuring advice and claims and underwriting audits, contributing to earnings and cash flows. We remain committed to underwriting discipline to achieve the best possible shareholder return, which is only possible through cycle management.

The lines of business of the Standard Property & Casualty Reinsurance segment are as follows:

General Third Party Liability

We provide a broad range of coverage for reinsurance of industrial, manufacturer, operational, environmental, product and general third-party liability. We provide liability coverage on both a proportional and non-proportional basis.

Motor

Motor insurance can include coverage in three major areas — liability, physical damage and accident benefits, for all of which we provide reinsurance coverage. Liability insurance provides coverage payment for injuries and for property damage to third parties. Physical damage provides for payment of damages to an insured automobile arising from a collision with another object or from other risks such as fire or theft. Accident benefits provide coverage for loss of income and medical and rehabilitation expenses for insured persons who are injured in an automobile accident, regardless of fault.

Personal Accident (assumed from non-life insurers)

We provide accident coverages for various business lines, including personal accident and travel accident.

Property

We reinsure liability for physical damage caused by fire and allied perils such as explosion, lightning, storm, flood, earthquake and for costs of debris removal, as well as coverage of business interruption and loss of rent as a result of an insured loss. Other sub-lines of Property reinsurance include cover for hail, burglary, water damage and glass breakage.

Specialty Lines

The Specialty Lines segment’s strategy is to develop specialty businesses in which Converium can position itself as a market leader and effectively leverage its intellectual assets in risk analysis, structuring, product design and risk modeling. We focus on specialty businesses because we believe that Converium possesses superior underwriting and structuring capabilities in certain areas, which is both a key driver of profitability as well as an effective barrier to entry in certain business lines.

Wherever possible, Converium seeks to develop preferred access to specialty lines through strong relationships, strategic partnerships or participations in entities that enjoy a unique position, such as strong control over the origination of their business, which prevent them from having to compete in annual insurance or reinsurance auctions. Examples of the approach by which we seek to develop preferred access to these businesses are our strategic partnership with MDU in the U.K and our participation in GAUM and our shares in its pools, as well as many strong relationships with specialized mono-line insurers.

In addition, Converium Underwriting Ltd, a Lloyd’s Corporate Member, has successfully provided and continues to provide third-party capacity to certain specialist Lloyd’s syndicates.

Due to the long-tail nature of many of the specialty lines of business, the emergence of accounting profit occurs after a time lag. The high levels of carried reserves necessary for the specialty lines of business underwritten by the segment can be capital consumptive during periods of strong growth in premiums written and may pose a constraint on the amount of growth and the business mix of the segment.

The lines of business of the Specialty Lines segment are as follows:

Agribusiness

We provide covers for specific named perils, traditional crop hail and bundled risks. These covers can apply to almost any product in the food and fiber chain: commodity crops, specialty crops and animal crops.

Aviation & Space

We provide reinsurance of personal accident and liability risks and hull damage in connection with the operation of aircraft and coverage of satellites during launch and in orbit.

Credit & Surety

Our credit coverages provide reinsurance for financial losses sustained through the failure for commercial reasons of an insured’s customers to pay for goods or services supplied to them. Our surety business relates to the reinsurance of risks associated with performance bonds and other forms of sureties or guarantees issued to third parties for the fulfillment of contractual obligations.

Engineering

We write all lines of engineering risks including project risks (construction all risk and erection all risk) and annual covers such as for machinery and electronic equipment, as well as consequential loss resulting from both project and annual risk.

Marine & Energy

We provide reinsurance relating to the property and liability coverage of goods in transit (cargo insurance) and the means of their conveyance (hull insurance).

Professional Liability and other Special Liability

We offer specialized underwriting, actuarial and claims expertise for professional liability, including medical malpractice, directors and officers, architects and engineers, accountants and lawyers liability. We also provide errors and omissions reinsurance coverage for specialized and other lines of business.

Workers’ Compensation

Our products include reinsurance for statutory workers’ compensation programs, as well as individual risk excess workers’ compensation.

Life & Health Reinsurance

The Life & Health Reinsurance segment contains the following lines of business:

•		Life & Disability; and

•		Accident & Health.

We offer these lines of business on an international scale. We primarily conduct our Life & Disability reinsurance business from Cologne, Germany. We have implemented a strategy to effectively grow our life reinsurance business. In addition, we have established branch offices in Milan and Paris. We also utilize our non-life offices in many parts of the world to facilitate direct contacts with our Life & Health Reinsurance clients.

As a result of these initiatives, our Life & Disability and Accident & Health lines of business written from our European offices have grown significantly in recent years, with our net premiums written increasing from USD 196.0 million in 2001 to USD 305.7 million at the end of 2006.

Our primary goal is to write Life & Health Reinsurance business that generates an attractive expected return. Our strategy focuses on:

•		maintaining underwriting discipline and pursuing business that is attractive on a risk-adjusted basis;

•		pursuing growth in markets we believe offer attractive opportunities, such as Germany, Italy, France and the Middle East;

•		maintaining a low expense ratio;

•		selectively providing services in certain target markets to build loyalty and attract premiums;

•		providing structured/finite solutions; and

•		leveraging our capital markets expertise which, among other things, provides us with additional capacity to write business.

We are seeking to grow our Life & Health business operations considerably while not compromising our underwriting standards. We believe that Life & Health Reinsurance will represent an increasing percentage of our business going forward.

We are focusing on the life reinsurance business because, among other reasons, we believe that the market for life reinsurance is growing. In addition, life reinsurance business tends to be less cyclical than non-life reinsurance due to more predictable claims experience.

We expect that the demand from life insurers for financial support and reinsurance services will continue to increase, particularly in Europe. We believe our capital markets and other non-traditional expertise will help us bring additional innovative solutions to our clients and further enhance the market position of our life operations.

In addition to the growth in our life insurance markets described above, we believe that the following factors will also contribute to increased demand for life reinsurance:

•		demutualizations of life insurance companies;

•		aging of the population;

•		privatization of benefits that used to be provided by governments;

Our underwriters coordinate to access our expertise and balance sheet capabilities to optimize solutions for our clients’ business needs. We have underwriting specialists throughout our worldwide organization, covering a wide range of disciplines that help us assess our risk exposures. In an effort to better serve our reinsurance clients, we combine our underwriters and actuaries in client management teams.

Specifically, we have access to significant internal actuarial expertise, which we deploy to assess pricing adequacy and to develop associated capital allocation approaches and risk models. Additionally, our underwriting process draws upon our multidisciplinary specialists, who include engineers, meteorologists, environmental scientists, economists, geologists, seismologists, physicist and mathematicians. These specialists and actuaries are based around the world and work together to ensure and facilitate the application of best practices and the consideration of the most recent scientific developments. Moreover, we actively utilize and develop risk models and other sophisticated tools, many of which are proprietary.

In developing underwriting guidelines, we formulate our risk demand, assess market conditions, quality of risks, past experience and expectations about future exposure. Where appropriate, we seek to limit our capacity on a per claim, per event and per year basis, and employ aggregate annual limits and index clauses, which reset retention in the event of claims inflation. The overall objective of these procedures is to achieve an appropriate expected return on equity while safeguarding our solvency and creditworthiness. In particular, we seek to maintain a sufficient level of overall capital to retain a strong financial capitalization under normal circumstances and an adequate capitalization after a significant loss.

During the underwriting process, we carefully seek to ensure that we employ coherent and consistent structures, pricing and wording such that all of our contracts and commitments are in line with our underwriting guidelines. Compliance with these rules is regularly reviewed by our senior management, who may effect adjustments as deemed appropriate. For non-standard transactions, our legal staff is involved both in transaction structuring and contract wording throughout the process.

Additionally, during the underwriting process, we assess and seek to control the amount and concentration of risk underwritten for various areas by analyzing aggregates and accumulation by region, peril or line of business, such as property catastrophe, aviation, Marine & Energy, Agribusiness and Credit & Surety. We normally use proprietary as well as commercially available tools to monitor our accumulations and relate them to our overall risk appetite. Aggregates are revised regularly and adapted in line with our current strategy and willingness and ability to bear risk, and transformed into rules and parameters for underwriting decisions.

We are committed to underwriting for profit. In pricing, we are committed to price to an after-tax target return that reflects the conditions in the investment markets and the riskiness of the portfolio. Meeting this target requires a constant management of the underwriting cycle including the avoidance of under-priced business.

We allocate capital to transactions based on how they contribute to our portfolio’s 1-in-100 year or worse losses. Business aggregating with existing treaties (that is, treaties that do not diversify well within our existing portfolio) are allocated a disproportionately larger amount of capital than treaties that diversify well. Similarly, larger treaties are allocated a disproportionately larger amount of capital than smaller treaties. This capital approach helps the portfolio become more diverse and optimizes the treaty mix.

In pricing business, we analyze various aspects of a prospective non-life reinsured’s business including, but not limited to, historical and projected loss and exposure data, expected future loss costs, historical and projected premium rate changes, financial stability and history, classes and nature of underlying business and policy forms, changes in the underlying risk exposure over time, underwriting and claims guidelines, aggregation of loss potential (between contracts), the dependence of risk factors relevant to the proposed policy with those relevant to the rest of our portfolio, existing reinsurance programs (including potential uncollectible reinsurance) and the quality and experience of management.

Our core pricing approach is to estimate the underlying frequency and severity of losses, adjusted for trends, so that we can develop an aggregate probability distribution of ultimate loss. In order to understand the cash flows, we estimate premium collection and loss payout patterns. Taking into account the transaction structure, we then create an aggregate probability distribution of the profit function of the contract that reflects risk-free investment income generated by the cash flows, commissions, brokerage, internal expenses and taxes. We estimate the risk capital by analyzing the treaty’s dependency on the current and future planned portfolio. Key factors that we utilize in the calculation of risk capital are the loss profile of the contract, the duration of the liabilities and the correlation of the risk factors with the remainder of our book of business. From this, the performance of the deal, or Performance Excess, is then computed as the expected profitability of the deal less the cost of capital.

We also consider other items in our pricing analysis such as client and line of business desirability and associated business opportunities. Whenever necessary, we develop or enhance additional tools to assess non-traditional or unusual structures. For specialized lines, such as Aviation, Agribusiness, Marine & Energy and Credit & Surety, we have developed and continue to enhance pricing models based on risk factors specific to those lines of business. Our comprehensive approach to risk modeling, and our integration of analytical expertise in client-focused teams, allows us to quantify the potential financial impact of these measurable risks.

Our models give us the capability to easily and quickly analyze a contract under numerous structures. This in turn allows us the flexibility to be creative, innovative and responsive in seeking to create a structure that satisfies our profit goals and risk appetite while simultaneously satisfying our clients’ objectives. Our modeling expertise and development of very efficient computational algorithms and simulations enable us to price different structures promptly. We are able to access our pricing system and databases online and from anywhere around the world.

In order to fully realize the value of this ability, we seek to gain a deep and thorough understanding of the subject business being covered. For most of our business, including all large and complex contracts, actuaries and other technical experts are part of the transaction team. They build the models and, jointly with the underwriters, price and structure the transaction. Often, they will also visit the client. For the remainder of our business, internal actuaries or other experts including engineers, meteorologists, environmental scientists, economists, geologists, seismologists, physicist and mathematicians provide the analytic tools for the underwriters’ use.

In order to provide maximum feedback to our underwriting teams, we have developed management information systems that track the profitability of each contract from the time it is written until the last dollar is paid. We compare ultimate loss ratios with our original expectations and use this information to populate our databases. We utilize this information to analyze the relationships between historic profitability and such variables as size of contract, production source, structure of transaction and size of client.

Non-life claims management

We have relationships with a large number of cedents. These cedents are domiciled in many countries around the world and typically apply local practices and regulations when handling losses. This leads to a wide variety of approaches, in among other things, setting individual claims reserves, recording loss data and handling loss adjustments. In particular, the legal systems, loss reporting and applicable accounting rules can vary greatly by country and can potentially lead to inconsistent information and information flow from our cedents to us, with respect to timing, format and level of detail. All of these factors need to be considered appropriately when managing and assessing claims.

Individual claims reported to our non-life operating units are monitored and managed by Claims Services personnel according to global guidelines and procedures. At this level, claims administration includes reviewing initial loss reports, monitoring claims handling activities of clients, requesting additional information where appropriate, establishing initial case reserves and approving payment of individual claims. Claims Services personnel have payment and case reserving authorities commensurate with individual experience.

In addition to managing reported claims and conferring with ceding companies on claims matters, our Claims Services team conducts periodic audits of specific claims and the overall claims procedures of our clients at the offices of ceding companies. We rely on our ability to effectively monitor the claims handling and claims reserving practices of ceding companies in order to establish the proper reinsurance premium for reinsurance agreements and to establish proper loss reserves. Moreover, prior to accepting certain risks, our Claims Services will, as requested by underwriters, conduct pre-underwriting claims audits of prospective ceding companies.

We attempt to evaluate the ceding company’s claims-handling practices, including the organization of their claims department, their fact-finding and investigation techniques, their loss notifications, the adequacy of their reserves, their negotiation and settlement practices and their adherence to claims-handling guidelines. Following these audits, Claims Services provides feedback to the ceding company, including an assessment of the claims operation and, if appropriate, recommendations regarding procedures, processing and personnel.

Our non-life operating units work together to coordinate issues in a cooperative effort involving claims services, actuarial, risk modeling and underwriting functions. For example, our Claims Services personnel help coordinate the reserving and analysis of headline loss event exposure across our organization.

The Claims Services team is able to provide value-added services to customers, e.g., assessment, consultation and issuing publications, including surveys on topics of interest.

Life operations underwriting and claims

We have developed underwriting guidelines, policies and procedures with the objective of controlling the quality and pricing of the life reinsurance business we write. Our life reinsurance underwriting process emphasizes close collaboration among our underwriting, actuarial, administration and claims departments. We determine whether to write reinsurance business by considering many factors, including the type of risks to be covered, ceding company retention and binding authority, product and pricing assumptions and the ceding company’s underwriting standards, financial strength and distribution systems.

We believe that one of our strengths is our expertise in medical underwriting. We seek to work closely with our clients and, as a value-added service, share this expertise in order to build client loyalty and better understand their risks.

We generally do not assume 100% of a life reinsurance risk and require the ceding company to retain at least 20% of every reinsured risk. We regularly update our underwriting policies, procedures and standards to take into account changing industry conditions, market developments and changes in medical technology. We also endeavor to ensure that the underwriting standards and procedures of our ceding client entities are compatible with ours. To this end, we conduct periodic reviews of our ceding companies’ underwriting and claims procedures.

Life, accident and disability claims generally are reported on an individual basis by the ceding company. In case of large, difficult or doubtful claims, cedents provide us with all supporting documents. We also investigate claims generally for evidence of misrepresentation in the policy application and approval process. In addition to reviewing and paying claims, we monitor both specific claims and overall claims handling procedures of ceding companies.

We monitor the loss development of our life reinsurance treaties and compare them to our expected returns on a regular basis. In the case of significant deviations, we may seek to negotiate alternative contract provisions, including increased premiums or higher retentions.

For our life reinsurance business, the interaction between our actuaries and underwriters is very close, as most of our underwriters are also mathematicians. We use commercial as well as proprietary tools to assess the profitability of the business. Our life underwriting seeks to ensure that our expected stream of distributable profits will earn an adequate risk-adjusted return. Our analysis also includes sensitivity measures to control the risk exposure of our life portfolio.

Catastrophe risk management and protection

Natural peril and man-made catastrophe risk management is an essential part of our overall corporate risk management plan. To help us measure and monitor our exposure to natural catastrophic events, we have established a line-of-business function that together with members of senior management with underwriting, actuarial, risk management and other specialized expertise, review relevant aspects of our catastrophe underwriting and risk management.

An integral part of our Global Catastrophe Risk Management is our Natural Hazards Team, located in Zurich. This specialized team is responsible for modeling our global catastrophe exposure, and provides support to underwriters and pricing actuaries in our offices around the world. Natural Hazards Team members are integrated with our actuarial and risk modeling staff. We believe that centralizing key catastrophe risk functions in our Natural Hazards Team helps produce a consistent catastrophe exposure analysis across our international operations. For example, our catastrophe risk specialists design, maintain and support state-of-the-art risk modeling software to which our underwriters have direct access.

In addition, we have adopted a central monitoring system (the Global Cat Data Platform), which helps us to manage our worldwide accumulations of catastrophe risk by peril and region. In our analyses we focus on key zones where we face a geographic concentration or peak exposures, such as European windstorm risk. This centralized analysis is essential for an international reinsurer such as Converium, since we may write business for the same peril or region from more than one of our worldwide offices. Also, we endeavor to monitor clash potential, both from lines other than property catastrophe as well as between certain perils and regions.

A major component of our natural catastrophe risk management approach is to employ global portfolio optimization and geographic diversification. By utilizing careful risk selection, pricing and modeling of portfolio additions, we seek to diversify our exposures

while optimizing available capacity and maximizing our expected return on equity. This approach helps us to fully capitalize on the natural catastrophe reinsurance premiums our balance sheet supports, while reducing the expected net impact of catastrophe losses. We believe this strategy leaves us well positioned to write additional business during periods of improving market conditions.

The principal goals of our natural hazard risk management procedures include:

•		Measuring, monitoring and managing natural hazard exposures: For measuring natural hazard exposures, we use specially developed software and techniques. For example, we use third-party models developed by specialized consultants to assist with catastrophe underwriting and accumulation control. We also compare models for certain perils or regions where our models indicate higher variability. In addition, we have developed fully proprietary probability-based monitoring tools to enhance the utility of our models.

		Our central monitoring system models loss potentials for storm and earthquake scenarios to help us measure our accumulation of risk by type of peril and geographic region. We continuously perform accumulation analyses during renewal season. We believe that this centralized review helps us monitor and manage our natural catastrophe loss potential and to take remedial action if there is a risk that our accumulations will reach levels that are not acceptable under our guidelines. In addition, our monitoring system serves as the basis for structuring our own reinsurance protection.

•		Assisting with optimal capacity utilization: We use return on risk based capital considerations to help us to optimize expected profits from our catastrophe portfolio and to seek to improve its performance. We do this by dynamically adjusting capacity allocation during renewal periods as business is written, thereby optimizing our worldwide capacity and exploiting our diversification potential. We also review pricing levels in several markets prior to renewal, in order to incorporate this information in our business strategy.

•		Supporting clients in all elements of natural hazards risk management: The expertise developed by our catastrophe risk specialists in understanding and managing catastrophe risk allows us to assist our clients in assessing their own loss potential and in designing efficient risk transfer mechanisms. Further, we utilize our expertise to influence property catastrophe exposure reporting in the industry. We believe that the use of data standards will improve data quality, enable more accurate risk assessment and reduce costs.

•		Following post-disaster loss developments: Our catastrophe risk specialists produce estimates of our expected losses promptly after a catastrophe event. This rapid review helps us assess our liquidity needs and determine whether we need to take any remedial action.

Historically, a majority of the natural catastrophe reinsurance we have written relates to exposures within Europe, Japan and the United States. Accordingly, we are exposed to natural catastrophic events which affect these regions, such as European windstorm, Japanese earthquake and US hurricane and earthquake events. Our estimated potential losses, on a probable maximum loss basis, before giving effect to our retrocessional protection, are currently managed to a self-imposed maximum gross event limit of USD 400 million for a 250-year return period loss.

We use retrocessional reinsurance protection to assist our efforts to ensure that our risk tolerance is not exceeded on a per event or aggregate basis. We actively seek to combine traditional reinsurance protection with capital market solutions, in order to diversify our sources of risk bearing capital. We have developed substantial capital markets expertise, which we can use both to provide additional capacity to our clients and to improve our own results and risk profile.

In 2006, we had the benefit of USD 81.0 million event limit from traditional reinsurance protections for our non-US property portfolio in excess of USD 50.0 million for any natural catastrophe affecting our property portfolio. In addition, we purchased cover for natural catastrophes affecting our non-US property portfolio in excess of USD 25.0 million with cover up to USD 50.0 million, whereby first-event coverage was limited to certain perils. This coverage is reviewed periodically and the majority of the coverage was placed with companies with a single A financial strength ratings or above.

In addition, in 2004, we entered into a transaction with Helix 04 Ltd (“Helix 04”), a dedicated Bermuda special purpose exempted company that ultimately provides us with specific high limit catastrophe protection. Helix 04’s business consists solely of issuing five-year catastrophe securities; Helix 04 entered into a counterparty contract with us whereby Helix 04 will make payments to us from its funds to cover defined catastrophic losses. The owners of the securities are entitled to receive their original investment, plus interest

on the notes, paid quarterly, less any loss payments made to us. The Helix 04 transaction replaced the Trinom transaction that we had in place since 2001. See Note 10 to our 2006 consolidated financial statements for additional information on Helix.

Payments from Helix 04 to Converium AG are based on modeled reinsurance losses on a notional portfolio. In a modeled loss contract, the covered party’s aggregate exposure to each geographical region and type of catastrophe, by line of business, is compared to industry-wide data in order to produce the covered party’s market share of particular loss events by line of business using commercially available natural catastrophe loss simulation modeling software. The software simulates a catastrophe, at various levels of severity, by generating certain probabilistic loss distributions, in order to calculate industry-wide losses and the corresponding losses for the covered party on a “ground-up basis”, by line of business. These losses are then compared to the modeled loss contracts to determine the amount of the covered party’s recovery in respect of such an event.

Converium exercised its right to reset the notional portfolio by notice on April 24, 2006 with an effective date of June 30, 2006 to realign the notional portfolio with Converium’s anticipated portfolio for the remaining three-year term of the contract.

The Helix 04 contract is first triggered when notional losses reach USD 154.8 million (USD 150.0 million before reset). The second trigger is hit when notional losses reach USD 176.2 million (USD 175.0 million before reset). It then pays out according to a sliding scale of notional losses up to USD 276.2 million (USD 275.0 million before reset).

Converium estimates its gross loss for each of the 2006 catastrophe events to be significantly less than the Helix 04 activation threshold of USD 154.8 million for each such event, and therefore; Converium will not file a trigger event request in respect of these losses.

The annual cost of Helix 04 to Converium is USD 6.1 million for the year ended December 31, 2006. The annual charge to Converium is not impacted by the occurrence of a loss event that is protected by Helix 04, unlike the prior contract in respect of Trinom, where Converium was required to pay higher amounts for the remainder of the term of the contract. The Helix 04 counter-party contract is not treated as reinsurance and accordingly the charge is reflected through other income (loss) although the cost of the counter-party contract is amortized over the term of the contract in a manner similar to reinsurance.

Unlike traditional reinsurance, the Helix 04 transaction is fully collateralized to eliminate any counterparty credit risk on recoveries. Helix 04 provides a second event protection over a five-year horizon, securing a fixed-price capacity, which cannot be impaired by a severe first industry event. Due to the nature of the transaction, we are exposed to modeling uncertainty, meaning that the modeled loss might deviate somewhat from the actual indemnity loss of the notional portfolio (basis risk).

Lastly, with respect to man-made catastrophes such as acts of terrorism, we have introduced an appropriate monitoring and accumulation approach. We utilize a matrix system to track for each contract the level of exclusion (absolute or partial, sub limit or other) and its level of exposure. While our methodology is being further developed and refined, it enables appropriate monitoring of our current exposure.

Retrocessional reinsurance

We purchase retrocessional reinsurance to better manage risk exposures, protect against catastrophic losses, access additional underwriting capacity and to stabilize financial ratios. The insurance or indemnification of reinsurance is called a retrocession, and a reinsurer of a reinsurer is called a retrocessionaire. We aggregate our ceded risk across our operations to achieve superior terms and pricing for our retrocessional coverage and to help us better assess our overall portfolio risk. Additionally, we incorporate the use of retrocessional coverage as a component of our underwriting process.

The major types of retrocessional coverage we purchase include the following:

•		specific coverage for certain property, engineering, aviation, motor and liability exposures;

•		catastrophe coverage for property business;

•		property clash coverage for potential accumulation of liability from treaties and facultative agreements covering losses arising from the same event or occurrence; and

We have established a control procedure whereby our Chief Executive Officer and Chief Risk Officer, along with the other members of our senior executive team, review the business purpose for all reinsurance purchases. One or more members of our senior executive team, generally our Chief Risk Officer, approve all purchases before they are bound.

Prior to entering into a retrocessional agreement, we analyze the financial strength and rating of each retrocessionaire and the financial performance and rating status of all material retrocessionaires is thereafter monitored. In addition, as part of our evaluation before purchasing reinsurance we also consider the accounting implications of the particular transaction.

Retrocessional reinsurance arrangements generally do not relieve Converium from its direct obligations to its reinsureds. Thus, a credit exposure exists with respect to reinsurance ceded to the extent that any retrocessionaire is unable or unwilling to meet the obligations assumed under the retrocessional agreements. At December 31, 2006 and 2005, Converium held USD 210.4 million and USD 470.6 million, respectively, in collateral as security under related retrocessional agreements in the form of deposits, securities and/or letters of credit.

In the event our retrocessionaires are not able or willing to fulfill their obligations under our reinsurance agreements with them, we will not be able to realize the full value of the reinsurance recoverable balance. We record a reserve to the extent that reinsurance recoverables are believed to be uncollectible. The reserve is based on an evaluation of each retrocessionaire’s individual balances and an estimation of their uncollectible balances.

Bad debt provisions of USD 11.3 million have been recorded for estimated uncollectible premiums receivable and reinsurance recoverables at December 31, 2006, compared with USD 28.1 million at December 31, 2005. The decrease is mainly due to the sale of our North American operations in December 2006.

The following table sets forth Converium’s ten largest retrocessionaires as of December 31, 2006, based on non-life underwriting reserves and future life benefits, and their respective Standard & Poor’s or A.M. Best financial strength rating.

As a consequence of the Formation Transactions, Converium AG has assumed both the benefits and the financial risks relating to third-party reinsurance recoverables under the Quota Share Retrocession Agreement. We manage all third-party retrocessions related to the business reinsured by Converium AG under the Quota Share Retrocession Agreement. ZIC and ZIB are obligated under the Quota Share Retrocession Agreement, during its term, to maintain in force, renew or purchase third-party retrocessions covering the business covered by the Quota Share Retrocession Agreement at our sole discretion.

In addition, Zurich Financial Services, through its subsidiaries, provided us with a degree of retrocessional reinsurance coverage following the Formation Transactions. In particular, Zurich Financial Services, through its subsidiaries, has agreed to arrangements that cap our net exposure for losses and loss expenses arising out of the September 11th terrorist attacks at USD 289.2 million (subsequently reduced to USD 231.0 million following the sale of our North American operations) the amount of loss and loss expenses we recorded as of September 30, 2001. As part of these arrangements, subsidiaries of Zurich Financial Services have agreed to take responsibility for non-payment by the retrocessionaires of Converium AG and Converium Rückversicherung (Deutschland) AG with regard to losses arising out of the September 11th attacks. Our only retrocessionaire for this business is a unit of Zurich Financial Services. Therefore, we are not exposed to potential non-payments by retrocessionaires for this

event in excess of the USD 289.2 million cap, although we will be exposed to the risk of non-payment of Zurich Financial Services units and we will be exposed to credit risk from these subsidiaries of Zurich Financial Services. Our recorded losses and loss expenses, net of retrocessional recoveries and the cap from ZFS through its subsidiaries, were reduced from USD 289.2 million to USD 231.0 million, following the sale of our North American operations.

In order to provide additional comfort in regards to our reserve position, in August of 2004 we acquired a retrospective stop-loss retrocession cover from National Indemnity Company, a Standard & Poor’s AAA-rated member of the Berkshire Hathaway group of insurance companies. The retrospective stop-loss retrocession cover was commuted in December 2006 in preparation for the sale of our North American Operations and after a review of coverage requirements. See Note 10 to our 2006 consolidated financial statements for additional information on this cover and for further information on retrocessional risk management.

Loss and loss expense reserves

Establishment of loss and loss expense reserves

We are required by applicable insurance laws and regulations and US GAAP to establish reserves for payment of losses and loss expenses that arise from our products. These reserves are balance sheet liabilities representing estimates of future amounts required to pay losses and loss expenses for insured claims which have occurred at or before the balance sheet date, whether already known to us or not yet reported. Significant periods of time can elapse between the occurrence of an insured claim and its reporting by the insured to the primary insurance company and subsequently by the insurance company to its reinsurance company. Loss reserves fall into two categories: reserves for reported losses and loss expenses, and reserves for losses and loss expenses incurred but not yet reported (“IBNR”).

Upon receipt of a notice of claim from a ceding company, we establish a case reserve for the estimated amount of the ultimate settlement. Case reserves are usually based upon the amount of reserves reported by the primary insurance company and may subsequently be increased or reduced as deemed necessary by our claims departments. We also establish reserves for loss amounts that have been incurred but not yet reported, including expected development of reported claims.

These IBNR reserves include estimated legal and other loss expenses. We calculate IBNR reserves by using generally accepted actuarial techniques. We utilize actuarial tools that rely on historical data and pricing information and statistical models as well as our pricing analyses. We revise reserves as additional information becomes available and as claims are reported and paid.

Our estimates of reserves from reported and unreported losses and related reinsurance recoverable assets are reviewed and updated periodically. Adjustments resulting from this process are reflected in current income. Our analysis relies upon the basic assumption that past experience, adjusted for the effect of current developments and likely trends, is an appropriate basis to estimate our current loss and loss adjustment expense liabilities. Because estimation of loss reserves is an inherently uncertain process, quantitative techniques frequently have to be supplemented by professional and managerial judgment. In addition, trends that have affected development of reserves in the past may not necessarily occur or affect reserve development to the same degree in the future.

The uncertainty inherent in loss estimation is particularly pronounced for long-tail lines such as umbrella, general and professional liability and motor liability, where information, such as required medical treatment and costs for bodily injury claims, will only emerge over time. In the overall reserve setting process, provisions for economic inflation and changes in the social and legal environment are considered. The uncertainty inherent in the reserving process for primary insurance companies is even greater for the reinsurer. This is because of, among other things, the time lag inherent in reporting information from the insurer to the reinsurer and differing reserving practices among ceding companies. As a result, actual losses and loss expenses may deviate, perhaps materially, from expected ultimate costs reflected in our current reserves.

In setting reserves, we utilize the same integrated, multi-disciplinary approach we use to establish our reinsurance terms and conditions. After an initial analysis by reserving actuaries, preliminary results are shared with appropriate underwriters, pricing actuaries, claims and finance professionals and senior management. Final actuarial recommendations incorporate feedback from these professionals.

CORE is our proprietary global loss reserve estimation system. It applies a number of standard actuarial reserving methods on a contract-by-contract basis. This allows us to calculate estimates of IBNR for each transaction based on its own characteristics. We aggregate the reserves indicated for each transaction to arrive at the total reserve requirement (“bottom-up approach”).

In addition to these bottom-up approaches we utilize standard top-down analyses. For these methods we aggregate the majority of our business into a limited number of homogeneous classes and apply standard actuarial reserving techniques. These top-down analyses provide an alternative view that is less dependent on pricing information. The comparison of these different approaches, namely bottom-up and top-down, provide additional insights into the reserve position and can lead to reserve adjustments in either bottom-up or top-down approaches or both.

In accordance with US GAAP, we do not establish contingency reserves for future catastrophic losses in advance of the event’s occurrence. As a result, a catastrophe event may cause material volatility in our incurred losses and a material impact on our reported income, subject to the effects of our retrocessional reinsurance. For further details on our catastrophe risk and reinsurance programs, see “— Catastrophe risk management and protection” and “— Retrocessional reinsurance”.

Core reserving methodology

Expected loss/expected loss ratio

Reinsurance contracts are typically priced using proprietary pricing models. The expected loss ratio for each reinsurance contract is normally the expected loss ratio derived at the pricing of the reinsurance contract and may be subject to adjustments based on re-pricing of the reinsurance contract.

All reserve indications are conducted at the reinsurance contract level typically on a gross and retroceded basis; net loss and allocated loss adjustment expense reserve indications are typically derived by netting gross and retroceded loss and allocated loss adjustment expense reserve indications. Unallocated loss adjustments expense reserve provisions are derived at the business segment level.

Our reserving tool applies a number of standard actuarial reserving methods on a contract-by-contract basis. This allows us to calculate estimates of IBNR for each transaction based on its own characteristics. We aggregate the reserves indicated for each transaction to arrive at the total reserve requirement (“bottom-up approach”).”

Every reinsurance contract is assigned to a reserving group referred to as a Reserve Equity Cell or REC. Each REC typically contains reinsurance contracts with identical or similar characteristics in respect to:

•		underlying risk (e.g. line of business), geographic region or treaty type (i.e. proportional or non-proportional); and

•		the time period at which losses are expected to be paid and reported (i.e. expected paid loss development factors and expected reported development factors).

For each REC, expected paid loss development factors and expected reported loss development factors are derived from either:

•		statistics developed by pricing actuaries, or

•		actual paid loss and reported loss (of the reinsurance contracts assigned to a given REC) aggregated into underwriting year triangles.

It is our policy to review regularly expected paid loss development factors and expected reported loss development factors for each REC.

For each REC and underwriting year, ultimate losses are projected using the following five standard actuarial methods:

•		Expected Loss Method (normally derived from pricing as described above);

•		Paid Loss Bornhuetter Ferguson Method;

•		Incurred Loss Bornhuetter Ferguson Method;

•		Paid Loss Development Method;

•		Incurred Loss Development Method.

For each reinsurance contract within a given REC and underwriting year, one reserving method is selected based on professional actuarial judgment. Standard practice is to select the expected loss method for a relatively immature underwriting year (i.e. underwriting year and REC for which the expected reported loss as at the valuation period (e.g., December 31, 2006) is less than 50% of the ultimate loss that will eventually be reported) when the actual loss experience is not yet deemed credible. In addition, actual reported losses and expected reported losses are compared and in cases where the actual versus expected are materially different, the reserving actuary may (especially if the actual losses reported are higher than expected) either:

•		select a different actuarial method (i.e. to be more responsive to actual loss experience);

•		revise the expected loss (see expected loss / expected loss ratio above);

•		revise the expected paid loss and / or expected reporting loss patterns.

The indicated ultimate loss is intended to represent the expected ultimate loss for the full exposure of each contract at the reserving date (e.g. December 31, 2006). Additional reserve provisions can be added for known losses (notified) that have not been recorded yet in our system.

Typically the indicated ultimate loss for each contract is then adjusted by the ratio of base earned premium to base ultimate premium in order to calculate a reserve provision (IBNR) only to the exposed / expired portion of the reinsurance contract as of the reserving date. The base premium excludes loss sensitive premium adjustments.

For each REC and underwriting year we select best estimate of ultimate losses within a reasonable range. The range estimates are done at the REC level and are not aggregated to the business segment or consolidated level.

Adequacy of reserves

Given the inherent uncertainty of the loss estimation process described above, we employ a number of methods to develop a range of estimates. On the basis of our actuarial reviews, we believe our liability for gross losses and loss expenses, referred to as gross reserves, and our gross reserves less reinsurance recoverables for losses and loss expenses ceded, referred to as net reserves, at the end of all periods presented in our financial statements were determined in accordance with our established policies and were reasonable estimates based on the information known at the time our estimates were made. These analyses were based on, among other things, original pricing analyses as well as our experience with similar lines of business, and historical trends, such as reserving patterns, exposure growth, loss payments, pending levels of unpaid claims and product mix, as well as court decisions and economic conditions. However, since the establishment of loss reserves is an inherently uncertain process, the ultimate cost of settling claims may deviate from our existing loss and loss adjustment expense reserves, perhaps materially. Any adjustments that result from changes in reserve estimates are reflected in our results of operations.

Development of prior years’ reserves: Converium has experienced moderate favorable developments of its loss reserves. Since 2002, Converium has recorded USD (425.6) million of favorable development from continuing operations on prior year’s non-life business (2002: USD (113.9) million; 2003: USD (195.7) million; 2004: USD 72.8 million; 2005 USD (86.0) million; and 2006 USD (102.8) million).

For the year ended December 31, 2006, Converium reported net favorable development of prior years’ loss reserves of USD 102.8 million. The Standard Property & Casualty Reinsurance segment was positively impacted by net favorable development of prior years’ loss reserves of USD 54.1 million primarily related to the Property and General Third Party Liability lines of business of USD 45.1 million and USD 24.6 million, respectively, partially offset by net adverse development of prior years’ loss reserves related to the Motor line of business of USD 16.5 million. The Specialty Lines segment was positively impacted by net favorable development of prior years’ loss reserves of USD 48.7 million primarily related to the lines of business: Aviation & Space and Engineering of USD 34.9 million and USD 16.2 million, respectively, partially offset by net adverse development of prior years’ loss reserves related to the Professional Liability and other Special Liability line of business of USD 17.6 million.

For the year ended December 31, 2005, Converium recorded net favorable development of prior years’ loss reserves of USD 86.0 million. The Standard Property & Casualty Reinsurance segment was positively impacted by net favorable development of prior years’ loss reserves of USD 30.7 million primarily related to the Property line of business of USD 73.3 million, partially offset by net adverse development of prior years’ loss reserves within the Motor and General Third Party Liability lines of business of USD 25.0 million and USD 23.4 million, respectively. The Specialty Lines segment was positively impacted by net favorable development of prior years’ loss reserves of USD 55.3 million primarily related to the Aviation & Space line of business of USD 57.5 million.

For the year ended December 31, 2004, Converium recorded net adverse development of prior years’ loss reserves of USD 72.8 million. The Standard Property & Casualty Reinsurance segment was negatively impacted by net adverse development of prior years’ loss reserves of USD 11.3 million primarily related to adverse development within the Motor line of business of USD 78.7 million, which was partially offset by net favorable development of prior years’ loss reserves related to the Property line of business of USD 77.8 million. The Specialty Lines segment was negatively impacted by net adverse development of prior years’ loss reserves of USD 61.5 million primarily related to adverse developments of the Professional Liability and other Special Liability and Engineering lines of business of USD 116.1 million and USD 13.7 million, respectively, partially offset by net favorable development of prior years’ loss reserves related to: Credit & Surety (USD 30.2 million), Aviation & Space (USD 24.6 million) and Workers’ Compensation (USD 16.4 million) lines of business.

The positive reserve development as described herein in “— Loss Reserve Development” have been determined in accordance with our loss reserving policies as described in “— Loss and Loss Adjustment Expense Reserves — Establishment of Loss and Loss Adjustment Expense Reserves”, and was recorded in accordance with our established accounting policies as described in Note 1(d) to our 2006 consolidated financial statements. Under these policies, we review and update our reserves as experience develops and new information becomes known, and we bring our reserves to a reasonable level within a range of reserve estimates by recording an adjustment in the period when the new information confirms the need for an adjustment.

Converium recently commissioned a reserve study by a major independent actuarial firm to analyze December 31, 2006 non-life loss and allocated adjustment expense reserves in depth, and the conclusions of this reserve study support the total level of corresponding booked gross and net reserves. The final version of this reserve study will be considered as part of the full range of information that Converium considers during the normal reserve assessment process in future quarters. Consequently, whilst there is support to the total level of reserves there could be fluctuations in lines of business or segments in future quarters.

Effects of currency fluctuations

A significant factor affecting movements in our net reserve balances has been currency exchange rate fluctuations. These fluctuations affect our net reserves because we report our results in US dollars. As of December 31, 2006, approximately 66% of our loss reserves are for liabilities that will be paid in a currency other than the US dollar. We establish these reserves in original currency, and then, during our consolidation process, translate them to US dollars using the exchange rates as of the balance sheet date. Any increase or decrease in reserves resulting from this translation process is recorded directly to shareholders’ equity and has no impact on current earnings. When new losses are incurred or adjustments to prior years’ reserve estimates are made, these amounts are reflected in the current year net income at the average exchange rates for the period.

Loss reserve development

The first table below presents changes in the historical non-life loss and loss adjustment expense reserves that we established in 1996 and subsequent years. The top lines of the tables show the estimated loss and loss adjustment reserves, gross and net of reinsurance, for unpaid losses and loss expenses as of each balance sheet date, which represent the estimated amount of future payments for all losses occurring prior to that date. The upper, or paid, portion of the first table presents the cumulative amount of payments of the loss and loss adjustment expense amounts through each subsequent year in respect of the reserves established at each initial year-end. Losses paid in currencies other than the US dollar are translated at consolidation into US dollars using the average foreign exchange rates for periods in which they are paid. The lower, or reserve re-estimated portion, gross and net of reinsurance, of the first table shows the re-estimate of the initially recorded loss and loss adjustment expense reserve as of each succeeding period-end, including claims paid, but recalculated using the foreign exchange rates for each subsequent period-end. The reserve estimates change as more information becomes known about the actual losses for which the initial reserves were established. The cumulative redundancy/(deficiency) lines at the bottom of the table are equal to the initial reserves less the liability re-estimated as of December 31, 2006.

Conditions and trends that have affected the development of our reserves for losses and loss expenses in the past may or may not necessarily occur in the future, and accordingly, our future results may or may not be similar to the information presented in the tables below.

The table below presents our loss and loss expense reserve development as of the dates indicated. These numbers also include our discontinued operations prior to 2006. The movements in 2006 reflect the sale of our North American operations in December 2006.

As a significant portion of our reserves relate to liabilities payable in currencies other than US dollars, any fluctuations of the US dollar to those currencies will have an impact on the reserve redundancy/(deficiency). As shown on the table above, the net reserve position for 1998 developed favorably from USD 2,530.3 million as of December 31, 1998 to USD 2,504.8 million as of December 31, 2006, reflecting a redundancy of USD 25.5 million. However, shown on the table below, applying the exchange rate as of December 31, 1998 to the 1998 reserves re-estimated as of December 31, 2006 would result in re-estimated reserves of USD 2,600.2 million, or a deficiency of USD (69.9) million, illustrating that a substantial part of the apparent redundancy is due to currency movements, which may or may not persist to the date claims are actually paid. As a result of these currency movements, the cumulative redundancy/(deficiency) shown above is considerably higher/(lower) as of December 31, 2006 than if the reserves were shown on a constant exchange rate basis for all years presented. Due to the inherent volatility of exchange rates, this effect may change in the future. Accordingly, we expect that future changes in foreign exchange rates will impact our reserve adequacy re-estimates. However, with respect to our primary currencies, we believe that the potential volatility of our liabilities is offset to a large extent by our efforts to invest in assets denominated in the same currency.

The table above also shows that our net loss reserves have developed more frequent redundancies/(lower deficiencies) than our gross loss reserves. Changes in estimates of our net losses directly impact our reported results. Accordingly, our estimates of reinsurance recoveries on incurred losses and our collections of those recoveries from our retrocessionaires also directly impact our reported results. See “— Retrocessional reinsurance” above for a discussion of the types of retrocessional reinsurance coverage that we purchase.

At December 31, 2006, we recorded USD 604.9 million of underwriting reserves, retro excluding reserves for life benefits, retro. Approximately 42.4% of this amount relates to recoverables in connection with the September 11th terrorist attacks.

The following table shows the development of our initial reserves net of reinsurance using the same exchange rates in effect when each of the initial reserves was set to re-estimate the reserves in subsequent years. These numbers also include our discontinued operations prior to 2006 and the movements in 2006 reflect the sale of our North American operations in December 2006.

The payment pattern of our loss and loss expense reserves varies from year to year. Based on historical payment patterns and other relevant data, we estimate that the mean time to payment, on an undiscounted basis, of our loss and loss expense provisions, including future life benefits, as of December 31, 2006, was 4.2 years. We expect this average payment period to change as our mix of business changes, as well as due to changes of payment patterns and fluctuations in currency exchange rates.

(1)		The loss and loss expenses incurred includes USD 114.2 million, USD 178.3 million and USD 128.0 million of loss and loss expenses included in the Life & Health reinsurance segment for the years ended December 31, 2006, 2005 and 2004, respectively.

(2)		Figures for 2005 and 2004 are as originally reported. Loss and loss expenses incurred and loss and loss expenses paid from discontinued operations were USD 55.8 million and USD 924.1 million and USD 948.1 million and USD 1,066.3 million for 2005 and 2004, respectively.

In 2006, Converium recorded USD 145.2 million of favorable development at the 2006 average exchange rate and USD 186.1 million of favorable development at the 2005 average exchange rate. See “ — Adequacy of Reserves”.

Prior years’ favorable net loss expenses incurred in 2006 of USD 145.2 million were primarily driven by net favorable development of prior years’ loss reserves of USD 102.8 million (See “— Adequacy of reserves”), and the reversal of reserves relating to prior years’ premium accruals in the amount of USD 42.4 million.

Prior years’ favorable net loss expenses incurred in 2005 of USD 111.2 million were primarily driven by net favorable development of prior years’ loss reserves of USD 86.0 million (See “— Adequacy of reserves”), and the reversal of reserves relating to prior years’ premium accruals in the amount of USD 25.2 million.

Prior years’ favorable net loss expenses incurred in 2004 of USD 101.5 million were primarily driven by net adverse development of prior years’ loss reserves of USD 72.8 million (See “— Adequacy of reserves”), the reduction of a reinsurance recoverable of USD 12.0 million, which was partially offset by the reversal of reserves relating to prior years’ premium accruals in the amount of USD 186.3 million.

Reserves for asbestos and environmental losses

We have exposure to liabilities for asbestos and environmental impairment from our assumed reinsurance contracts, primarily arising from business written by Converium Rückversicherung (Deutschland) AG, historically known as Agrippina Rückversicherung AG and subsequently known as Zürich Rückversicherung (Köln) AG (“ZRK”). Our asbestos and environmental exposure primarily originates from US business written through the London Market and from treaties directly written with reinsurers in the United States.

We cancelled our relevant London Market reinsurance contracts in 1966 and 1967. At the time, we reduced our participation in asbestos and environmental-exposed US treaties, with the eventual result that Converium Rückversicherung (Deutschland) AG ceased property and liability underwriting in the United States in 1990. Due to uncertainties as to the definitions and to incomplete reporting from clients, exact separation of asbestos and environmental exposures cannot be reached. Converium AG’s exposure is also minimal because, under the terms of the Quota Share Retrocession Agreement, Converium AG will only reinsure business written with an inception or renewal date on or after January 1, 1987. In 1986, our contract wording was revised, consistent with a general industry change, such that asbestos and environmental claims were generally excluded.

As of December 31, 2006 and 2005, our total loss and adjustment expense reserves, including additional reserves and IBNR reserves, for US-originated asbestos and environmental losses were approximately USD 49.2 million, respectively for each year or 0.9% and 0.7%, respectively of our total net reserves for losses and loss expenses, respectively. This provision includes reserves originally communicated by our cedents, together with additional reserves we established.

We estimate that the survival ratio of our asbestos and environmental risk portfolio, calculated as the ratio of reserves held, including IBNR, over claims paid over the average of the last three years, was 13.8 years at December 31, 2006 and 14.1 years as of December 31, 2005. Survival ratio is an industry measure of the number of years it would take a company to exhaust its reserves for asbestos and environmental liabilities based on that company’s current level of claims payments.

Reserving for asbestos and environmental claims is subject to a range of uncertainties that has historically been greater than those presented by other types of claims. Among the complications are a lack of historical data, long reporting delays and uncertainty as to the number and identity of insureds with potential exposure. In addition, there are complex, unresolved legal issues regarding policy coverage and the extent and timing of contractual liability.

These uncertainties and issues are not likely to be resolved in the near future. Consequently, traditional loss reserving techniques cannot wholly be relied on and, therefore, the uncertainty with respect to the ultimate cost of these types of claims is greater than the uncertainty relating to standard lines of business. In addition, changes to existing legal interpretation, new legislation or new court decisions could materially impact our reserves, results of operations, cash flows and financial position in future periods.

Investments

Our overall financial results are in large part dependent upon the quality and performance of our investment portfolio. Net investment income and net realized capital gains (losses) accounted for 13.4%, 11.4% and 7.7% of our revenues for the years ended December 31, 2006, 2005 and 2004, respectively.

Our assets are invested with the objective of achieving investment returns consistent with those of the markets in which we invest, using state-of-the-art risk management techniques to optimize, diversification, tax regulatory and liquidity considerations. We principally focus on high quality, liquid securities and seek to invest in securities whose durations correspond to the estimated payout patterns of the reinsurance liabilities they support.

Our approach to fixed income investments is to limit credit risk by focusing on investments rated predominantly “A” or better by Standard & Poor’s, Moody’s or similar rating agencies, and to reduce concentration risk by limiting the amount that may be invested in securities of any single issuer or group of issuers. With respect to equity investments, we seek to diversify our equity portfolio so as to provide a broad exposure across major sectors of individual stock markets. To reduce the effects of currency exchange rate fluctuations, we seek to match the currencies of our investments with the currencies of our underlying reinsurance liabilities.

Our investments are managed mostly by external investment managers, and their performance is measured against benchmarks. Our investment practices are governed by guidelines established and approved by our Board of Directors. Although these guidelines stress diversification of risks, conservation of principal and liquidity, these investments are subject to market-wide risks and fluctuations, as well as risks inherent in particular securities.

As of December 31, 2006 and 2005, total invested assets (excluding cash and cash equivalents) were USD 5,765.3 million and USD 6,634.3 million, respectively.

The sale of our North American operations in December 2006 resulted in a decrease of total invested assets including cash and cash equivalents of USD 883.2 million.

The table below presents the carrying value of our consolidated investment portfolios as of December 31, 2006, 2005 and 2004.

In 2006, we liquidated our private equity investments in a secondary market transaction from the investment portfolio in our North American operations to reflect the run-off situation and to accommodate expected for upcoming liquidity requirements. Due to the sale of our North American operations and their concentration on investments in fixed maturities securities, our allocation to fixed maturity securities declined significantly. For the continuing operations, in the second half of 2006, we sold twelve Swiss direct real estate holdings together with 800,000 shares of PSP Swiss Property AG and reallocated the proceeds into Real Estate Investment Trusts (“REITs”). Furthermore, in line with our asset/liability management (“ALM”) approach, we realigned our investment portfolio towards our strategic asset allocation, whereby, we increased our exposure to equity securities by approximately USD 240.0 million to 8.3% and modestly increased our alternative investments exposure by investments in hedge funds.

Fixed maturities

As of December 31, 2006, our fixed maturities portfolio, excluding the Funds Withheld Asset (described more fully below), had a carrying value of USD 3,840.8 million and represented 60.0% of our total investment portfolio including cash and cash equivalents (74.7% including the Funds Withheld Asset). This represents a decrease in carrying value of USD 1,122.6 million, or 22.6%, from December 31, 2005. This decrease was primarily driven by the liquidation of available for sale fixed maturity securities in connection with the sale of our North American operations.

We invest in government, agency and corporate fixed income securities of issuers from around the world that meet our liquidity and credit standards. We place an emphasis on investing in listed fixed income securities that we believe to be liquid.

The table below presents the composition of our fixed income securities portfolio, excluding short-term investments, based on carrying value by scheduled maturity.

Most of our fixed income securities are rated by Standard & Poor’s, Moody’s or similar rating agencies. As of December 31, 2006, approximately 92.9% of our fixed income securities portfolio was invested in securities rated A or better by these agencies and approximately 83.3% was invested in AAA/Aaa rated securities.

The table below presents the composition of our fixed income securities portfolio by rating as assigned by Standard & Poor’s or Moody’s, using the lower of these ratings for any security where there is a split rating.

Equity securities

As of December 31, 2006, our equity securities portfolio had a carrying value of USD 734.7 million (including PSP Swiss Property AG and REITs). This represents an increase in carrying value of USD 372.1 million, or 102.6%, from December 31, 2005, which was due to the strategic investment decision to increase our holdings in equity securities. Equity securities, excluding PSP Swiss Property AG and REITS, were approximately 8.3% and 3.9% of our total investment portfolio, including cash and cash equivalents, as of December 31, 2006 and December 31, 2005, respectively.

Our equity portfolio consists of listed securities held either directly or through funds. Substantially, all the equity portfolios are invested in developed markets. As experienced in recent years, the equity markets around the world can produce highly volatile and significantly varied results due to local and worldwide economic and political conditions.

As of December 31, 2006, we have no exposure to private equity investments as compared with approximately USD 46.9 million for the same period of 2005. In 2006, we liquidated our private equity investments in a secondary market transaction from the investment portfolio in our former North American operations to reflect the run-off situation and to accommodate expected for upcoming liquidity requirements.

As of December 31, 2006 and 2005, gross unrealized gains on our equity securities portfolio were USD 121.8 million and USD 76.0 million and gross unrealized losses were USD 1.7 million and USD 1.1 million, respectively. We have reviewed the securities that have declined in value and have recorded impairments accordingly. See “Item 5. — Operating and financial review and prospects — A. Operating results —Critical accounting policies” for additional information on our impairment policy.

Our guidelines also restrict our maximum investment in any one equity security or industry sector by reference to local benchmarks and applicable insurance regulations. As of December 31, 2006, excluding our investments in funds, no single equity security represented more than 5% of our equity securities portfolio.

Funds Withheld Asset

The transfer of certain historical reinsurance business to Converium was affected as of July 1, 2001 by means of the Quota Share Retrocession Agreement with ZFS. In addition, on that date, the Funds Withheld Asset was established. Its initial balance was set to match the net balance of the liabilities, less the premium receivables (including outstanding collectible balances and reinsurance deposits) on the business to which the Quota Share Retrocession Agreement applies. As of December 31, 2006, the Funds Withheld Asset was USD 940.7 million. The decrease of USD 79.4 million over December 31, 2005 was substantially due to paid claims.

In general, the Funds Withheld Asset is reduced by paid claims, profit commissions, amounts paid to maintain the retrocession agreements and other amounts paid on the business subject to the Quota Share Retrocession Agreement and is increased by premiums (less premium refunds), salvage and subrogation, recoveries under retrocession agreements, profit commissions and other amounts received for the business subject to the Quota Share Retrocession Agreement. The balance of the Funds Withheld Asset will decrease over time. However, business historically written on the Zurich Insurance Company (“ZIC”) and Zurich International (Bermuda) Ltd (“ZIB”) balance sheets was written on the Converium balance sheet and continued to be renewed, where it met Converium’s profitability targets. As a result, we will generate operating cash flow from the new and renewal business written by Converium, which we expect to at least partially offset reductions of the balance of the Funds Withheld Asset.

See Note 16 to our 2006 consolidated financial statements for additional information on the Funds Withheld Asset and a recent change to the underlying agreement.

Short-term investments

Our short-term investment portfolio includes investments in fixed-term deposits and fiduciary investments. These investments generally have maturities of between three months and one year. As of December 31, 2006, we had short-term investments with a carrying value of USD 44.9 million, representing 0.7% of our total investment portfolio, including cash and cash equivalents. Short-term investments at December 31, 2005 were USD 35.1 million or 0.5% of our total investment portfolio, including cash and cash equivalents.

Real estate

At December 31, 2006, we had real estate held for investment through a direct real estate fund of USD 44.7 million, consisting primarily of investments in commercial real estate in the Eurozone. Our real estate investments, both direct and indirect totaled USD 144.6 million at December 31, 2005. Converium sold its Swiss direct real estate holdings in the fourth quarter of 2006 and reinvested the proceeds in diversified global real estate investment trust securities, which are included in the equity securities category. As of December 31, 2006, the total amount invested in REITs was USD 148.1 million. In addition to these direct and indirect real estate investments, Converium owns a 2.0% participation in PSP Swiss Property AG (an indirect real estate investment, included within the equity securities category) with a market value of USD 56.0 million as of December 31, 2006 compared with USD 76.8 million or 3.8% in 2005. In the third quarter of 2006, we sold 800,000 shares representing 1.8% of participation in PSP Swiss Property AG for proceeds of USD 40.9 million. Our total real estate portfolio represented 3.9% of our total investment portfolio, including cash and cash equivalents.

Other investments

As of December 31, 2006 and December 31, 2005, we had USD 168.5 million and USD 107.4 million, respectively in funds of hedge funds. This investment is included under the caption “Other investments” in the balance sheet.

Premiums receivable

We had premiums receivable of USD 880.9 million at December 31, 2006 compared with USD 1,059.3 million at December 31, 2005, a decrease of USD 178.4 million, or 16.8%. Premiums receivable include those currently due, as well as deferred premiums receivable, which is comprised primarily of accruals on premium balances which have not yet been reported and which are not contractually due to be paid until some time in the future. Current premiums receivable represented 13.0% and 18.3% of total premiums receivable at December 31, 2006 and December 31, 2005, respectively and accrued premiums receivable represented 87.0% and 81.7%, respectively. Bad debt provisions of USD 9.2 million have been recorded for estimated uncollectible premiums receivable at December 31, 2006, compared with USD 11.6 million at December 31, 2005.

Reinsurance assets

As of December 31, 2006, we had reserves for unpaid losses, loss expenses and future life benefits from retrocessionaires of USD 647.2 million compared with USD 805.1 million at December 31, 2005. The reduction is primarily due to the sale of the North American operations.

Capital expenditures

For the three years ended December 31, 2006, we invested a total of USD 6.7 million in fixed assets. Most of these amounts were invested in equipment and information technology, and were financed from our free cash flow. Capital investments will considerably increase in the next two years due to major enhancements with the replacement of our current reinsurance administration systems with a new integrated reinsurance software package with total projected costs of USD 17.0 million.

Ratings

During the course of 2006, Converium interacted frequently with Standard & Poor’s and A.M. Best. On February 28, 2007, Standard & Poor’s Ratings Services raised its long-term counterparty credit and insurer financial strength ratings on Switzerland-based reinsurer Converium AG and its long-term insurer financial strength ratings on guaranteed operating entities Converium Rückversicherung (Deutschland) AG and Converium Insurance (U.K.) Ltd. to “A-” from “BBB+”. At the same time, Standard & Poor’s removed these ratings from CreditWatch, where they had been placed with positive implications on Oct. 17, 2006. The outlook on all entities is stable.

Regulation

General

The business of reinsurance is regulated in most countries, although the degree and type of regulation varies significantly from one jurisdiction to another. Reinsurers are generally subject to less direct regulation than primary insurers in most countries. In Switzerland and Germany, we operate under relatively less intensive regulatory regimes. Historically, neither Swiss nor German regulations have materially restricted our business. However, in the United States, licensed reinsurers must comply with financial supervision standards comparable to those governing primary insurers.

This regulation, which is described in more detail below, generally is designed to protect policyholders rather than investors, and relates to such matters as rate setting; limitations on dividends and transactions with affiliates; solvency standards which must be met and maintained; the licensing of insurers and their agents; the examination of the affairs of insurance companies, which includes periodic market conduct examinations by the regulatory authorities; annual and other reports, prepared on a statutory accounting basis; establishment and maintenance of reserves for unearned premiums and losses; and requirements regarding numerous other matters. US regulations accordingly have in the past materially affected our US business operations, although not, we believe, in a manner disproportionate to or unusual in our industry. We allocate considerable time and resources to comply with these requirements, and could be adversely affected if a regulatory authority believed we had failed to comply with applicable law or regulation.

We believe that Converium and all of its subsidiaries are in material compliance with all applicable laws and regulations pertaining to their business and operations. Set forth below is a summary of the material regulations applicable to us.

Switzerland

Converium AG has received an operating license from the Federal Office of Private Insurance (Bundesamt für Privatversicherungen) (the “FOPI”), an administrative unit of the Swiss Ministry of Finance (Eidgenössisches Finanzdepartment) and is subject to the continued supervision by the FOPI pursuant to the Swiss Insurance Supervisory Act of December 17, 2004 (Versicherungsaufsichtsgesetz) (“ISA”). The FOPI has supervisory authority as well as the authority to make decisions to the extent that the Swiss Ministry of Finance is not explicitly designated by law. On January 1, 2006 a completely revised ISA together with an Implementing Ordinance entered into force. The main changes are an amended definition of solvency (Art. 9) which includes consideration of financial and operational risks, an emphasis on risk management aspects, the control of corporate governance elements by the FOPI and an increased transparency and consumer protection. The most important new feature is the introduction of the Swiss Solvency Test (“SST”), a risk-based capital model which preempts the forthcoming changes in the EU based upon the proposed EU Solvency II Directive. Insurance undertakings are allowed to use their internal risk models if they comply with certain conditions of a qualitative, quantitative and organizational nature defined and accepted by the FOPI. Furthermore, as a result of the revised ISA, FOPI may decide to establish a Group Supervision over Converium, in accordance with Art. 65 of the ISA. By virtue of the relevant provisions on Group Supervision as defined in the revised ISA, Converium companies outside of Switzerland could become the subject of certain supervisory powers of FOPI.

Unlike insurance business, which is strictly regulated in Switzerland, regulation of reinsurance business is less intensive and most of the technical rules for direct insurers are not applicable to the reinsurance business. The supervision exercised by the FOPI is mainly indirect through the supervision of direct insurance companies and the reinsurance arrangements which they have established. Reinsurance companies from other countries which conduct only reinsurance business in Switzerland from their foreign domicile are exempt from supervision by the FOPI. Based upon a decree of the Federal Council of November 30, 2001, a commission has been constituted to consider a revision of the overall framework of the Swiss banking and insurance supervision. The first part of the report was released in July 2003 by the commission. The proposal includes the formation of a uniform financial services authority, which will become the supervisory authority for banks (currently supervised by the Federal Banking Commission) and insurance (currently supervised by the FOPI).

Under current regulations, Swiss insurance and reinsurance companies cannot operate in any field other than reinsurance and insurance. This rule is subject to exceptions, which are granted by the FOPI. Generally, these exceptions are granted if the nature and volume of the proposed non-insurance or non-reinsurance business does not threaten the solvency of the company. Investments in an entity operating outside the reinsurance or insurance field are subject to supervisory authority approval if the investment represents more than 20% (or 10% in the case of a life insurance business) of the share or cooperative capital of the non-insurance entity or if the investment represents more than 10% of the insurer’s or reinsurer’s shareholders’ equity.

The FOPI requires each reinsurance company to submit a business plan which provides details about the calculation of its technical reserves and about its retrocession policies, and information about the reinsurer’s solvency. The FOPI initially examines documents relating to the company’s solvency, organization and management. If all legal requirements are met, an operating license is granted by the Swiss Ministry of Finance. Thereafter, companies must submit an annual business report, including financial statements, detailing information on all aspects of their business activities, such as premium income, paid out benefits, reserves and profits.

By letter dated September 27, 2004, the FOPI has requested that Converium AG provide notice on certain intra-group transactions between Converium AG and its subsidiaries including loans, guarantees, cost sharing agreements, capital injections, and investments in subsidiaries. Furthermore the FOPI requested by letter dated October 14, 2004 certain additional information including Converium’s business strategy, planning, reserves, solvency and collateral issues. Converium is cooperating with the FOPI and is providing all required information and documentation.

In December 2004, per the FOPI’s request, Converium AG agreed to submit for approval the following intra-group transactions: intra-group loans and capital increases to subsidiaries exceeding USD 100.0 million; guarantees exceeding USD 10.0 million; transfer of portfolios or novations involving changes in reserves exceeding USD 25.0 million, dividends to Converium Holding AG and all intra-group reinsurance transactions that are not at arm’s length. Absent consent of the FOPI, the intra-group transactions exceeding the thresholds cannot be executed, which may in turn have an impact on the funding in conjunction with intra-group transactions.

United States

US reinsurance regulation of our non-US reinsurance subsidiaries

Converium AG and Converium Rückversicherung (Deutschland) AG, our non-US reinsurance subsidiaries, also assume reinsurance from primary US insurers. In order for primary US insurers to obtain financial statement credit for the reinsurance obligations of our non-US reinsurers, our non-US reinsurers must satisfy reinsurance requirements. Non-US reinsurers that are not licensed in a state generally may become accredited by filing certain financial information with the relevant state commissioner and maintaining a US trust fund for the payment of valid reinsurance claims in an amount equal to the reinsurer’s US reinsurance liabilities covered by the trust plus an additional USD 20 million. In addition, unlicensed and unaccredited reinsurers may secure the US primary insurer with funds equal to its reinsurance obligations in the form of cash, securities, letters of credit or reinsurance trusts.

Terrorism legislation

On November 26, 2002, President George W. Bush signed into law the Terrorism Risk Insurance Act of 2002 (“TRIA”). This legislation establishes a program under which the Federal government will share the risk of loss arising from future terrorist attacks with the insurance industry. The law does not apply to reinsurers, and the federal government does not share in the risk of loss emanating from future terrorist attacks with the reinsurance industry. Each reinsurer is free to make its own contractual arrangements with its ceding partners, as it deems appropriate.

Regarding our ceding companies, TRIA, provides for the federal government to share with the insurance industry the risk of loss from certain future terrorist attacks. Each participating insurance company must pay covered losses equal to a deductible based on a percentage of direct earned premiums for specified commercial insurance lines from the previous calendar year. TRIA was originally scheduled to expire at the end of 2005, but was extended in December 2005 for an additional two years. As extended, the insurer deductible will be increased from 15% in 2005 to 17.5% in 2006 and 20% in 2007. For losses in excess of a company’s deductible, the federal government will cover 90.0% of the excess losses in 2006, while companies retain the remaining 10.0%, with the government’s share decreasing to 85.0% in 2007. Losses covered by the program remain capped annually at USD 100.0 billion. The extended TRIA will establish a new program trigger under which federal compensation will become available only if aggregate insured losses sustained by all insurers exceed USD 50.0 million from a certified act of terrorism occurring after March 31, 2006 and

USD 100.0 million for losses resulting from a certified act which occurs on or after January 1, 2007. This new trigger will be in addition to the USD 5.0 million certification threshold for an event to be certified.

Congress is considering an extension to TRIA. However, we cannot assure you that TRIA will be extended beyond 2007 or whether it will be extended on a permanent or temporary basis, and its expiration could have an adverse effect on our clients, the industry or us.

Legislative and regulatory proposals

New federal legislation, the Non-Admitted and Reinsurance Reform Act of 2007 (the “NRRA”) has been introduced in the U.S. House of Representatives. If enacted in its present form, the NRRA would establish the U.S. ceding insurer’s domiciliary state as the sole regulatory authority with respect to credit for reinsurance and establish steam lined processes for the procurement and regulation of non-admitted surplus lines insurance. In addition, the Insurance Industry Competition Act of 2007 (the “IICA”) has been introduced in the U.S. Senate and the U.S. House of Representatives. If enacted in its current form, the IICA would remove the insurance industry’s antitrust exemption created by the McCarran-Ferguson Act, which provides that insurance companies are exempt from federal antitrust law so long as they are regulated by state law, absent boycott, coercion or intimidation.

State law initiatives affecting the insurance and reinsurance markets in the U.S. and worldwide also continue to evolve. For example, Florida has enacted recent insurance reforms which significantly increase the state’s subsidy of insurance rates. The legislation allows Citizens Property Insurance Corp., traditionally the state’s insurer of last resort, and private insurers to purchase property catastrophe reinsurance from the Florida Hurricane Catastrophe Fund at prices well below current market prices. Such reforms may cause a decline in premiums assumed by the private reinsurance industry.

We are unable to predict whether any of the foregoing proposed legislation, or any other proposed laws and regulations will be adopted, the form in which any such laws and regulations would be adopted, or the effect, if any, these developments would have on our operations and financial condition.

European Union directives

Our businesses in the United Kingdom and Germany, as well as in the other member states of the EU and the European Economic Area, (the “EEA”), are impacted by EU directives. These directives are implemented through legislation in each member state. Switzerland, which is not a member state of the EU, entered into a treaty with the EU in 1989 which allows Swiss direct insurers, other than life insurers, the free establishment of branches and subsidiaries within the EU. Without being part of the EEA or being bound by contract, Switzerland reviews and largely conforms its financial services regulations to EU directives.

The new EU Reinsurance Directive adopted on November 16, 2005 is based largely on solvency related concepts stipulated in the prior directive adopted by the European Union (the “EU”) for insurance companies. The Directive does not provide for any discrimination of non-EU based reinsurance companies. However, if the individual EU member states, in implementing the EU Reinsurance Directive, should include any discriminatory regulations with respect to reinsurers of a non-EU member state, this could be a disadvantage for Converium AG in its doing business in the EU, as Converium AG derives a substantial proportion of its revenues within the EU and any competitive disadvantage we face there could have an adverse effect on our financial condition, results of operations or cash flows. However, a large portion of those revenues are being written through our subsidiary in the EU member state Germany, where no negative impact can arise from the implementation of the directive. In addition Converium has a second subsidiary in the UK, which also is an EU member.

Germany

Converium Rückversicherung (Deutschland) AG is regulated in Germany and is engaged exclusively in the reinsurance business. It is thus an insurance enterprise within the meaning of the German Insurance Supervision Act and as such is subject to governmental supervision. This supervision is exercised by the Federal Insurance Supervisory Office (BaFin) located in Bonn, Germany.

Until the end of 2004, and in contrast to insurance enterprises, companies that had been engaged exclusively in reinsurance activities were subject to a less extensive scope of governmental supervision. The supervisory authority’s monitoring of reinsurers was limited to ensuring their compliance with the specific accounting regulations applicable to insurance enterprises. For this purpose, reinsurance enterprises were required to submit quarterly and annual financial statements to the supervisory authority.

In addition, reinsurers were obligated to submit detailed reports on the nature and volume of their business to the supervisory authority in accordance with the Ordinance on Reporting by Insurance Enterprises to the Federal Insurance Supervisory Office.

Under the old regime, German reinsurers used to only be supervised indirectly, principally through the supervision of primary insurance companies. In particular, the Federal Insurance Supervisory Office requires German insurance companies to monitor their reinsurance agreements, which has led to the creation of internal rating systems for reinsurers by German insurance companies.

The German legislative has passed an enhanced supervisory act that now fully integrates the reinsurance industry into the regulatory scheme applicable to the insurance industry under the EU Directive on reinsurance. See “— European Union directives”. The new law became effective on January 1, 2005. The new regulation has an impact on various aspects of reinsurers, including legal form of the company, location of the headquarters, qualification of the executive management, control procedures towards shareholders, investment principles, solvency requirements and special intervention rights for the supervising bodies.

The supervisory authority may, at its discretion, perform inspections at the reinsurer’s premises to verify compliance with these statutory obligations.

The remaining items of the EU directive have been prepared for a white paper. The German federal cabinet decided on this paper on April 25, 2006 and submitted it to the parliament for approval. The new law is expected to become effective in 2007 and contains issues such as:

•

implementation of the principle of supervision in the member state of the company’s head office;

•

approval of the European stock corporation as a form of enterprise;

•

additional supervision of reinsurers within an insurance group;

•

introduction of regulations for finance reinsurance;

•

supervision of special purpose vehicles; and

•

introduction of the supervision of branches belonging to reinsurance companies in countries outside the EU-member countries.

In addition, extensive work has been initiated by the local German supervisory authority and the German insurance association in order to prepare for a risk based solvency system (Solvency II), which should be similar to the Basel II requirements enacted for the banking industry. Solvency II is not expected to be released prior to 2008/2009.

German Branch Office

In December 2004, Converium AG established a branch office in Cologne, Germany. This move was made in response to the favorable legal regulatory environment in Germany as the rules regarding establishment of branch offices were changed as of January 1, 2005. We do not currently transact any business in this branch.

Asia

Restrictions imposed by the Monetary Authority of Singapore

Citing developments affecting the Converium Group, in 2004 the Monetary Authority of Singapore had imposed certain restrictions on the conduct of our business originating from our Singapore branch.

Following our ratings upgrade to single A -, the Monetary Authority of Singapore lifted these restriction on March 26, 2007.

C. ORGANIZATIONAL STRUCTURE

Converium Holding AG has substantially no net assets other than its ownership of 100% of the shares in each of Converium AG, Zurich, Converium Finance (Bermuda) Ltd., and Converium IP Management Ltd., Zug. As of December 31, 2006, Converium AG

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS

A. OPERATING RESULTS

The following discussion and analysis should be read in conjunction with our 2006 consolidated financial statements, including the related notes to those financial statements. This discussion contains forward-looking statements that involve risks and uncertainties and actual results may differ materially from the results described or implied by these forward-looking statements. See “Cautionary note regarding forward-looking statements”.

Overview

In non-life reinsurance, our lines of business include General Third Party Liability, Motor, Personal Accident (assumed from non-life insurers), Property, Agribusiness, Aviation & Space, Credit & Surety, Engineering, Marine & Energy, Professional Liability and other Special Liability and Workers’ Compensation. In Life & Health Reinsurance, our lines of business include Life and Disability reinsurance, including quota share, surplus coverage and financing contracts and Accident & Health.

On December 13, 2006, Converium sold its North American operations, which was placed into orderly run-off in 2004, to National Indemnity Company, a Berkshire Hathaway company, for total consideration of USD 295.0 million comprising of USD 95.0 million in cash and USD 200.0 million in assumption of debt. Converium has not provided any guarantee or indemnity in respect of the reserves of the North American operations. The transaction was approved by the Insurance Department of the State of Connecticut. Our North American operations were previously reported as the principal component of a separate segment, the Run-Off segment. Converium’s financial results of the North American business, including prior period amounts, have been reclassified to discontinued operations. For further details regarding the sale of the North American operations, see Note 2 to our 2006 consolidated financial statements.

We prepare segregated financial information for each of our operating segments. In the future, we plan to continue conducting our business and measuring our financial and operating performance based on these segments.

We derive our revenues principally from:

•		premiums from our non-life and life reinsurance and insurance businesses;

•		investment income and investment gains from our portfolio of invested assets, net of investment expenses; and

•		interest on premium and loss deposits withheld by our clients.

Our costs and expenses principally consist of:

•

losses and loss expenses, which include:

	•		non-life reinsurance and insurance losses and loss expenses;

	•		death and other life reinsurance benefits;

•

operating and administration costs, which include:

	•		treaty and individual risk acquisition costs, commonly referred to as commissions;

	•		overhead costs, predominantly consisting of salaries and related costs;

•		interest expenses; and

•		income taxes.

Our profitability depends to a large extent on:

•		the quality of our underwriting and pricing;

•		the level of incurred losses and commissions;

•		the timing of loss and benefit payments;

•		our ability to earn appropriate yields on our investment portfolio;

•		our ability to manage operating and administration costs; and

•		our ability to efficiently and effectively manage risk, including retrocessions.

When reviewing our financial statements, there are certain business characteristics that affect the reporting of our results. The most significant factors are set forth below.

Critical accounting policies

Our discussion and analysis of the financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). The preparation of these financial statements in accordance with US GAAP requires the use of estimates and judgments that affect the reported amounts and related disclosures. Changes in our financial and operating environment could influence the accounting estimates that support our financial statements. The following presents those accounting policies that management believes are the most critical to its operations and those policies that require significant judgment on the part of management. The assumptions and judgments used by management are the ones they believe to be the most appropriate at this time. However, as described below, these estimates could change materially if different information or assumptions were used. The descriptions below are summarized and have been simplified for clarity. A more detailed description of these and other significant accounting policies used by us in preparing our financial statements is included in the Notes to the Consolidated Financial Statements.

Non-life loss and loss expense reserves

We are required by applicable insurance laws and regulations, as well as US GAAP, to establish reserves for payment of losses and loss expenses that arise from our non-life reinsurance and insurance businesses. Loss and loss expense reserves are based on estimates of future payments to settle claims, including legal and other expenses. The liability for unpaid losses and loss expenses for property and casualty business includes amounts determined from loss reports on individual cases (“case reserves”) and amounts for losses incurred but not yet reported (“IBNR”), including expected development of reported claims. Upon receipt of a notice of claim from a ceding company, we establish a case reserve for the estimated amount of the ultimate settlement. Case reserves are usually based upon the amount of reserves reported by the primary insurance company and may subsequently be increased (“additional case reserves” or “ACR’s”) or reduced if necessary to reflect our best estimate of the liability, by our claims departments. Our cedents are domiciled in

many countries around the world and typically apply local practices and regulations when handling losses. This leads to a wide variety of approaches, in among other things, setting individual claims reserves, recording loss data and handling loss adjustments. In particular, the legal systems, loss reporting and applicable accounting rules can vary greatly by country and can potentially lead to inconsistent information and information flow from our cedents to us, with respect to timing, format and level of detail. These factors are considered when managing and assessing claims and establishing loss reserves and should be noted when reviewing the gross reserve splits in the table below.


					Total gross non-life loss
	Case reserves		IBNR		reserves
Standard Property & Casualty		1,423.6		1,141.9		2,565.5
Specialty Lines		1,940.3		1,558.0		3,498.3
Life & Health Reinsurance		79.5		205.3		284.8
Total		3,443.4		2,905.2		6,348.6

The Life & Health Reinsurance segment contains loss reserves related to Accident and Health business.

If a contract is commuted, we reduce loss and loss expenses carried on our balance sheet and record a gain or loss for the difference between loss and loss expenses carried on our balance sheet and the commutation payment.

We estimate our loss and loss expense reserves on the basis of facts reported to us by ceding companies and in conjunction with actuarial estimates and methodologies for instances where we have not received reports from ceding companies. Our estimates of losses and loss expenses are subject to assumptions reflecting economic and other factors such as inflation rates, changes in legislation, court rulings, case law and prevailing concepts of liability, which can change over time. In addition, if ceding company data is not provided to us on a timely basis, this could potentially impact the accuracy of our estimates. The risks associated with making the estimate for assumed loss reserves include, among other things, those uncertainties prevalent in making assumptions for long-tailed lines of business, the time lag in information reporting by cedents and differing reserving approaches among cedents.

The amount of time that elapses before a claim is reported to the cedent and then subsequently reported to the reinsurer is commonly referred to in the industry as the “reporting tail”. Lines of business for which claims are reported quickly are commonly referred to as “short-tailed” lines; and lines of business for which a longer period of time elapses before claims are reported to the reinsurer are commonly referred to as “long-tailed” lines. The uncertainty inherent in loss estimation is particularly pronounced for long-tail lines such as umbrella, general and professional liability and motor liability, where information, such as required medical treatment and costs for bodily injury claims, will only emerge over time. In the overall reserve setting process, provisions for economic inflation and changes in the social and legal environment are considered. The uncertainty inherent in the reserving process for primary insurance companies is even greater for the reinsurer. This is because of, among other things, the time lag inherent in reporting information from the insurer to the reinsurer and differing reserving practices among ceding companies.

As a consequence, the estimation of loss and loss expense reserves is dependent on many assumptions and selection of parameters, and their combination. One of the most critical assumptions, particularly for lines with long-tail characteristics, is the selection of the reporting tail. The reporting tail is the period of time that elapses before a claim is reported to the cedent and then subsequently reported to the reinsurer. A change of this factor can lead to a substantially different estimate of ultimate losses and therefore reserves for loss and loss expenses. This change in the tail factor could be triggered by any of the drivers mentioned above, or a combination thereof.

As a result of these uncertainties and other factors, actual losses and loss expenses may deviate, perhaps materially, from expected ultimate costs which are reflected in our current reserves. This is evident in our actual experience of prior years’ calendar year favorable net loss expenses incurred development, which was as follows:


			Favorable development of
			prior years’ net loss
	Net loss reserves		expenses incurred during		Development on prior
	beginning of year		the year		years' loss reserves (%)
2004		4,614.7		101.5		2.2
2005		5,817.7		111.2		1.9
2006		5,498.2		145.2		2.6

The current year development reflects the composite effect of the factors described above. It is not possible to identify the effect of each individual factor because of the inter-relationship between such factors.

Prior years’ favorable net loss expenses incurred in 2006 of USD 145.2 million were primarily driven by net favorable development of prior years’ loss reserves of USD 102.8 million, and the reversal of reserves relating to prior years’ premium accruals in the amount of USD 42.4 million.

Prior years’ favorable net loss expenses incurred in 2005 of USD 111.2 million were primarily driven by net favorable development of prior years’ loss reserves of USD 86.0 million and the reversal of reserves relating to prior years’ premium accruals in the amount of USD 25.2 million.

Prior years’ favorable net loss expenses incurred in 2004 of USD 101.5 million were primarily driven by net adverse development of prior years’ loss reserves of USD 72.8 million, the reduction of a reinsurance recoverable of USD 12.0 million, which was partially offset by the reversal of reserves relating to prior years’ premium accruals in the amount of USD 186.3 million.

We, like other reinsurers, do not separately evaluate each of the individual risks assumed under reinsurance treaties, therefore we are largely dependent on the original underwriting decisions made by ceding companies. We are subject to the risk that our ceding companies may not have adequately evaluated the risks to be reinsured and that the premiums ceded to us may not adequately compensate us for the risks we assume. To mitigate this risk our claims departments conduct periodic audits of specific claims and the overall claims procedures of our clients at the offices of ceding companies. We rely on our ability to effectively monitor the claims handling and claims reserving practices of ceding companies in order to establish proper loss reserves. Moreover, prior to accepting certain risks, our claims departments are often requested by underwriters to conduct pre-underwriting claims audits of prospective ceding companies. We attempt to evaluate the ceding company’s claims-handling practices, including the organization of their claims departments, their fact-finding and investigation techniques, their loss notifications, the adequacy of their reserves, their negotiation and settlement practices and their adherence to claims-handling guidelines. Following these audits, the claims departments provide feedback to the ceding company, including an assessment of the claims operation and, if appropriate, recommendations regarding procedures, processing and personnel.

We use historical loss information in our assessment/analysis of existing loss reserves and/or as a means of noticing unusual trends in the information received from the cedents. Our analyses of estimated loss reserves are based on, among other things, original pricing analyses as well as our experience with similar lines of business and historical trends, such as reserving patterns, exposure growth, loss payments, pending levels of unpaid claims and product mix, as well as court decisions and economic conditions. Our estimates of reserves from reported and unreported losses and related reinsurance recoverable assets are reviewed and updated periodically. Adjustments resulting from this process are reflected in current income. Our analyses rely upon the basic assumption that past experience, adjusted for the effect of current developments and likely trends, is an appropriate basis to estimate our current loss and loss expense liabilities. Because estimation of loss reserves is an inherently uncertain process, quantitative techniques frequently have to be supplemented by professional and managerial judgment. In addition, trends that have affected development of reserves in the past may not necessarily occur or affect reserve development to the same degree in the future.

The impact of changes in loss estimates can be mitigated by risk diversification. Risk diversification is a basic risk management tool in the insurance and reinsurance industry; as a multi-line reinsurer there are always likely to be reserve adjustments at the line of business level. Our book of business is broadly diversified by line of business as well as balanced by region and by the expected duration of its claims obligations.

Our Standard Property and Casualty Reinsurance segment is primarily comprised of short and medium-tail lines of business and accounted for 40.4%, 40.0%, and 45.4% of our gross non-life loss and loss expense reserves at December 31, 2006, 2005 and 2004, respectively. Our Specialty Lines segment is primarily comprised of medium and long-tail lines of business and accounted for 55.1%, 55.2% and 50.3% of our gross non-life loss and loss expense reserves at December 31, 2006, 2005 and 2004, respectively. As discussed in the reporting tail description above, this factor can have a significant impact on the volatility of reserves and the uncertainties that exist in the reserve estimation process.

Premiums

When we underwrite business, we receive premiums for assuming the risk. Premiums written in any given period include premiums reported to us by our clients and those we estimate and accrue on contracts underwritten. Reported premiums written and earned are based upon reports received from cedents, supplemented by our own estimates of premiums written for which ceding company reports

have not been received.

In a typical reporting period, we generally earn a portion of the premiums written during that period together with premiums that were written during earlier periods. Likewise, some part of our premiums written will not be earned until future periods. We allocate premiums written but not yet earned to an unearned premium reserve, which represents a liability on our balance sheet. As time passes, the unearned premium reserve is gradually reduced and the corresponding amount is released through the income statement as premiums earn. Premiums are typically earned on a pro-rata basis over the period that the coverage is in effect. Our premium earned and written estimates are regularly reviewed and enhanced as information is reported to us by our clients and we are able to refine our estimates and assumptions. Differences between such estimates and actual amounts are recorded in the period in which estimates are changed or the actual amounts are determined.

A key assumption used by Management to arrive at its best estimate of assumed premiums is its assessment of expected reporting lags. In addition, they also use the following assumptions: (i) estimated written premium, (ii) change in mix of business; and (iii) ceding company seasonality of premium writing.

Management uses information provided by ceding companies as the initial basis for determining its premium accrual estimates and then further refines it based on known trends within the industry and the book of business.

We write a wide range of different types of insurance and reinsurance policies, some of which are earned during periods shorter than one reporting period, while some are earned during substantially longer periods. This mix of business can change significantly from one period to the next and these changes can cause the relationship between written and earned premiums to differ, perhaps significantly, on a year-to-year basis. Typically, differences in the percentage growth or decline between premiums written and earned mainly reflect this difference in our mix of business from year to year. Our underwriters and client relationship managers, in their analysis of trends, relate the change in premiums earned to the change in premiums written.

Similarly, the seasonality of premium writings are also analyzed on a regular basis by our underwriters and client relationship managers, taking into account the underlying business, the local market environments and emerging trends.

Our estimation procedures are also affected by the timeliness and comprehensiveness of the information our clients provide to us. The time lag between the release of this information from the ceding company to us can be significant and depends on the reporting frequency of the underlying accounts.

Consideration receivable for a retroactive reinsurance contract is recognized as premiums earned at the inception of the contract.

Deposit accounting

In the ordinary course of business, we both purchase, or cede and sell, or assume, property and casualty reinsurance protection. For both ceded and assumed reinsurance, risk transfer requirements mainly those in SFAS 113, “Accounting and Reporting for Reinsurance of Short-Duration and Long-Duration Contracts” must be met in order to obtain reinsurance accounting, principally resulting in the recognition of cash flows under the contract as premium and losses. If risk transfer requirements are not met, a contract is to be accounted for under deposit accounting, typically resulting in the recognition of cash flows under the contract as a deposit asset or liability and not as revenue or expense. Generally, to meet risk transfer requirements, a reinsurance contract must include both insurance risk, consisting of underwriting and timing risk and a reasonable possibility of a significant loss for the assuming entity.

Reinsurance and insurance contracts that include both significant risk sharing provisions, such as adjustments to premiums or loss coverage based on loss experience and relatively low policy limits as evidenced by a high proportion of maximum premium assessments to loss limits, can require considerable judgment to determine whether or not risk transfer requirements are met. For such contracts, often referred to as finite or structured products, we require that risk transfer be specifically assessed for each contract by developing expected cash flow analyses at contract inception. To support risk transfer, the cash flow analyses must support the fact that a significant loss is reasonably possible. For purposes of cash flow analyses, we generally use a risk-free rate of return consistent with the expected average duration of loss payments. In addition, to support insurance risk, we must prove the reinsurer’s risk of loss varies consistently with that of the reinsured and/or support various scenarios under which the assuming entity can recognize a significant loss.

In the event that a transaction does not meet risk transfer requirements, the transaction will be accounted for in accordance with AICPA Statement of Position 98-7, “Deposit Accounting: Accounting for Insurance and Reinsurance Contracts That Do Not Transfer Insurance Risk” (“SOP 98-7”). SOP 98-7 applies to proposed, assumed and ceded reinsurance transactions that fail risk transfer because there is (1) underwriting risk and timing risk but the underwriting risk is not significant or (2) significant underwriting risk but timing risk is not significant, or (3) underwriting risk and timing risk but not significant underwriting and timing risk. In general, most of the assumed finite transactions underwritten by Converium fail the risk transfer test because there is underwriting risk and timing risk but the underwriting risk is not significant. In these instances a deposit asset/liability is recognized on the balance sheet based on the net cash flows of the transaction. These amounts accrete interest income/expense utilizing the effective interest method based on amounts ultimately estimated to be paid and the time to settlement of the asset/liability. Most of the finite transactions also include a non-refundable fee (reinsurer’s margin) which is retained by the reinsurer irrespective of the experience on the contract. This fee is recognized as other income/expense over the coverage period of the policy and is not recorded as a deposit asset/liability.

In the event that the circumstances change and a loss will be ceded to the contract which will not ultimately be supported by an interest rate that can be earned on the deposit, then the deposit will be recognized into income/expense over the coverage period of the contract and a loss liability/recoverable will be recognized equal to the expected losses on the contract discounted by the risk free rate in accordance with SOP 98-7.

Reinsurance recoverables

We cede reinsurance to retrocessionaires in the normal course of business. Under US GAAP, reinsurance is recorded gross in the balance sheet. Reinsurance assets (recoverables) include the balances due from retrocessionaires for paid and unpaid losses and loss expenses, ceded unearned premiums and ceded future life benefits. Amounts recoverable from retrocessionaires are estimated in a manner consistent with the liabilities associated with the reinsured contracts.

Retrocessional reinsurance arrangements generally do not relieve us from our direct obligations to our reinsureds. Thus, a credit exposure exists with respect to reinsurance ceded to the extent that any retrocessionaire is unable or unwilling to meet the obligations assumed under the retrocessional agreements. Failure of retrocessionaires to indemnify us due to insolvencies or disputes could result in uncollectible amounts and losses to us. We establish an allowance for potentially uncollectible recoverables from retrocessionaires for amounts owed to us that management believes will not be collected. In addition, we immediately charge operations for any recoverable balances that are deemed to be uncollectible. Collateral and other offsets are considered in determining the allowance or expense.

Foreign currency translation

We report our financial information in US dollars. However, a large portion of our revenues and expenses are denominated in other currencies including the Euro, UK pound, Swiss franc and Japanese yen. Since these currencies are functional currencies for our business units, translation differences are recorded directly in shareholders’ equity.

Invested assets

The majority of our fixed maturities and equity securities are classified as available-for-sale; these investments are carried at fair value. Fixed maturities for which we have the intent and ability to hold to maturity are classified as held-to-maturity. Held-to-maturity securities are carried at amortized cost, if purchased, or carrying value, if transferred from the available-for-sale category to the held-to-maturity category. The difference between the fair value and amortized cost at the date of transfer of such securities is amortized over the life of the respective securities. The carrying value of transferred securities is the fair value at the date of transfer less unamortized net unrealized gains. Fixed maturities and equity securities, which we buy with the intention to resell in the near term, are classified as trading and are carried at fair value. Unrealized gains or losses on investments carried at fair value, except those designated as trading, are recorded in other comprehensive income, net of deferred income taxes.

Investments in which the Company has significant influence over the operating and financial policies of the investee are accounted for under the equity method of accounting. Under this method, the Company records its proportionate share of income or loss from such investments in its results for the period. Any decline in value of equity method investments considered by management to be other than temporary is charged to income in the period in which it is determined.

Other- than- temporary impairment

Based on quantitative and qualitative factors, the Company reviews at least quarterly individual debt and equity securities classified as held-to-maturity or available-for-sale, for whether or not there is an indication that a decline in fair value below the investment security’s carrying value is considered other-than-temporary.

If the decline in fair value is judged to be other-than-temporary, and management does not have the intent and ability to hold the investment until recovery, impairment is deemed to have occurred and the cost basis of the security shall be written down to fair value as the new cost basis. The amount of this write-down should be recognized as impairment of securities in the statement of income.

For all marketable and non-marketable equity and debt securities where the cost basis has remained in excess of the fair value for twelve months consecutively and the fair value has declined by 20% or more of the cost basis, except in circumstances where potential recovery for equity securities can be conclusively demonstrated and documented, the declines will be presumed to be other-than-temporary and thus impaired and must be written down to the fair value. Furthermore, management believes that where there is a 50% or more magnitude of decline, an impairment provision should immediately be recognized.

For securities expected to be sold, an other-than-temporary charge should be recognized if the Company does not expect the fair value to recover prior to the expected date of sale.

Converium has outsourced investment management to recognized and experienced professional funds managers that operate and are monitored in relation to the specific investment guidelines of the Company and has sufficient control to support our ability and intent assertions where applicable.

Income taxes

Deferred income taxes are provided for all temporary differences that are based on the difference between the financial statement carrying amounts and the income tax bases of assets and liabilities, tax effected using enacted local income tax rates and laws. In addition, a deferred tax asset has been established for net operating loss carry forwards. Converium has significant net operating loss carry forwards that the Company can use to offset future taxable income. Realization of the deferred tax asset related to these carry forwards is dependent upon generating sufficient taxable income within specified future periods. Converium establishes a valuation allowance against its net deferred tax asset based upon its assessment if it is more than likely than not that some or the entire deferred tax asset will not be realized in the applicable jurisdiction. In establishing the appropriate valuation allowance against its deferred tax asset, Converium must, to the extent that no valuation allowance has been established, make judgments about its ability to recognize the benefit of the asset over time, including its ability to utilize the net operating loss carry forwards.

The Company does not affirmatively apply the exception to the recognition of deferred taxes under Accounting Principles Board Opinions No. 23 (APB23), “Accounting for Income Taxes—Special Areas”, and therefore is required under SFAS No. 109 to provide for taxes on the undistributed earnings of its foreign subsidiaries and foreign corporate joint ventures. However, due to various factors, including no positive undistributed earnings in any foreign subsidiaries or joint ventures and the availability of the participation exemption, no provision for taxes is made on earnings of the foreign subsidiaries and joint ventures.

Converium is subject to income taxes in Switzerland and various foreign jurisdictions. Significant judgment is required in determining the Company’s worldwide provision for income taxes and recording the related assets and liabilities. In the ordinary course of the Company’s business, there are many transactions and calculations where the ultimate tax determination is uncertain. Accruals for tax contingencies are provided, if necessary, in accordance with the requirements of SFAS No. 5, “Accounting for Contingencies".

Goodwill and other intangible assets

Goodwill and intangible assets with an indefinite life are no longer amortized with effect from January 1, 2002, in accordance with SFAS 142. The Company continues to review the carrying value of goodwill related to all of its investments for any impairment on an annual basis. If it is determined that an impairment exists, the Company adjusts the carrying value of goodwill to fair value. The impairment charge is recorded in the period in which it is determined.

remaining unamortized balance of the intangible asset will be amortized on a straight-line basis over the newly determined expected useful life of the asset. See Note 7 to our 2006 consolidated financial statements for further information on goodwill and intangible assets

Investment results

Investment results are an important part of our overall profitability. Our net investment income increased by USD 2.6 million, or 1.0% for the year ended December 31, 2006 as compared with the same period in 2005. The average total invested assets remained largely unchanged. However, the lower income contribution from the Funds Withheld Asset which was attributable to the declining balance on this asset, was more than offset by higher investment income from short dated investments reflected in other investment income, due to generally higher yields as a result of an inverted yield curve environment. Our net investment income increased by USD 30.3 million, or 13.3% for the year ended December 31, 2005 as compared with the same period in 2004. The increase largely resulted from growth in total invested assets during 2005, and a reallocation from equity securities into income generating fixed maturities securities. We paid fees in the amount of USD 8.1 million, USD 9.8 million and USD 11.6 million to our asset managers and custodians in 2006, 2005 and 2004, respectively, including other investment-related costs. Our average net investment income yield (pre-tax) was 4.2% for the year ended December 31, 2006 as compared with 4.2% and 3.9% for the same periods in 2005 and 2004, respectively.

An increasing component of net investment income arises from income received on business written on a funds withheld basis such as certain Lloyd’s transactions. As these assets are reported under funds held by reinsureds and do not form part of the average total invested assets, while the investment income from these funds held by reinsureds is included in our net investment income, there is an increase of 0.2 points for 2006 in the reported average net investment income yield (pre-tax). Excluding this effect, the average net investment income yield (pre-tax) would have been 4.0%, 3.9% and 3.7% for the years ended December 31, 2006, 2005 and 2004, respectively.

The following table shows the average pre-tax yields and investment results on our investment portfolio for the years ended December 31, 2006, 2005 and 2004.

(1)		In line with the income statement presentation for discontinued operations, yields have been calculated by excluding the North American operation’s invested assets from the average total invested assets sums for 2005 and 2004

Our average total investment income yield (pre-tax) was 4.5% for the year ended December 31, 2006 as compared with 4.7% for 2005 and 4.5% for 2004. Yields are calculated based on the average of beginning and ending total invested asset balances (including cash and cash equivalents). The total investment income yield was slightly lower in 2006 as compared with 2005. In 2006, net realized gains were predominately driven by the sale of Swiss direct real estate holdings, while realized gains on equity securities were offset by realized losses on fixed maturities securities and impairment. The 2005 and 2004 yields were positively impacted by realized gains resulting from the sale of equity securities to adjust our asset allocation in order to reduce investment portfolio risks. In addition, our average total investment income yield (pre-tax) was negatively impacted by USD 11.7 million, USD 9.2 million and USD 6.2 million of impairment charges during 2006, 2005 and 2004, respectively.

Our average total investment return (pre-tax) was 5.0% for the year ended December 31, 2006 as compared with 4.5% and 4.6% for the same periods in 2005 and 2004, respectively. Our 2006 total investment return was positively impacted by the strong performance of equity securities markets and hedge funds, which also resulted in positive changes in unrealized gains. Additionally, the sale of our North American operations reduced total unrealized losses by USD 26.5 million. This positive development was partially offset by the lower valuation on fixed maturities securities due to yield curve shifts. In 2005, the change in net unrealized gains was driven by a reduction in net unrealized capital gains due to the realization of gains triggered by the sale of equity securities, partially offset by the continued positive development of the stock markets.

Pursuant to the agreement signed on March, 15, 2007 with Deutsche Asset Management AG to offer strategic investment support, we initiated a project to evaluate the continued classification of investments into available for sale and held to maturity accounting categories.

Restructuring costs

For the year ended December 31, 2006 we incurred a restructuring benefit of USD 0.2 million due to the release of restructuring accruals as compared with expenses of USD 12.1 million for the same period in 2005. In 2005, the reduction in overall business volume required organizational changes and an adjustment to our global cost base including employee terminations and closure of smaller offices. In 2004 we recorded restructuring costs of USD 0.2 million.

Income tax

We are subject to local income tax requirements in the jurisdictions in which we operate. Significant judgment is required in determining our worldwide provision for income taxes and recording the related assets and liabilities. The income tax expense in our financial statements therefore reflects a number of different local tax rates, and as a result may change from one period to the next depending on both the amount and the geographic contribution of our taxable income or loss. In addition, the income tax we pay is based on local tax returns in which our reported income or loss and expenses may differ from that reported in our financial statements.

As a result of changes in our geographic contribution of taxable income or loss as well as changes in the amount of our non-taxable income and expense and changes in our valuation allowance, the relationship between our reported income before tax and our income tax expense may change significantly from one period to the next.

Converium recorded an income tax expense of USD 40.5 million and USD 16.1 million for the years ended December 31, 2006 and 2005, respectively and an income tax benefit of USD (4.6) million for the year ended December 31, 2004. Our global effective tax rate for continuing operations was 15.9% for the year ended December 31, 2006 as compared with 32.1% and (21.9)% for the same periods of 2005 and 2004, respectively. For the year ended December 31, 2006, Converium’s consolidated income tax expense of USD 40.5 million comprised of USD 10.3 million of current income tax expense and USD 30.2 million of deferred income tax expense. The current income tax portion reflects the net tax paying position of some affiliated companies. Due to the establishment of a full valuation allowance in 2004 on the net deferred tax position for certain affiliates in Switzerland, no deferred income tax expense has been reported for these entities. For all other jurisdictions the Company applies the annual effective tax rate to calculate the income tax expense on a jurisdiction-by-jurisdiction basis.

As of December 31, 2006, Converium had total net operating losses carried forward of USD 1,040.5 million available to offset future taxable income of certain branches and subsidiaries. All of these net operating losses carried forward relate to Converium Rückversicherung (Deutschland) AG and Converium AG. Converium AG’s net operating losses expire in the years 2011 through 2013. The benefits of these carryforwards are dependent on the generation of taxable income in those jurisdictions in which they arose and accordingly, a valuation allowance has been provided where management has determined that it is more likely than not that the carryforwards will not be utilized.

As a result of the rating upgrade in 2007, “roadmap to sustainable value creation” and other events occurring post year end, the company completed the regular assessment of the need for a valuation allowance as at March 31, 2007, and determined that a substantial release was required during 2007. Each quarter Converium reassesses the need for a valuation allowance in light of all available information, which could result in a change in this position.

For further information about our income tax expenses, see Note 12 to our 2006 consolidated financial statements.

Regulatory and legislative environment

Our business is subject to regulation in all of the jurisdictions in which we operate. Regulation includes compliance with applicable laws covering operating and reporting requirements, monitoring of solvency and reserves and asset valuation. Changes in government policy or taxation also may affect our results of operations. In addition, political, judicial and legislative developments could broaden the intent and scope of coverage of existing policies written by our clients, which may result in additional liabilities for reinsurers. See “Item 4. — Information on the Company — B. Business Overview — Regulation”.

For the year ended December 31, 2006, we reported income from continuing operations of USD 215.0 million compared with USD 34.1 million for the same period in 2005. Our 2006 figures demonstrate the quality of our 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, our results were positively impacted by the net favorable impact of prior accident years on the technical result of USD 52.1 million, resulting from net favorable development of prior years’ loss reserves of USD 102.8 million, which were offset by reductions in premiums and other expenses of USD 50.7 million.

However, the costs of defending the class actions, see “Item 8. — Financial Information —A. Consolidated Statements and Other Financial Information — Class Action Lawsuits”, may have a material impact on our operating results in future reporting periods and an unfavorable outcome could have a materially adverse effect on the Company’s financial condition, results of operations and cash flows.

The (loss) income from discontinued operations comprises of the sale of the North American operations (discontinued business), which were sold to the National Indemnity Company. In 2006, loss from discontinued operations was USD 157.9 million, consisting of a total transaction loss of USD 190.1 million which was recognized upon the completion of the sale on December 13, 2006. This was offset by income from operations of discontinued business of USD 32.2 million.

Net income from operations of discontinued business was USD 32.2 million and USD 34.6 million for the years ended December 2006 and 2005, respectively compared with a net loss for the year ended December 2004 of USD 608.1 million. The positive results in 2005 reflect commutations after our North American operations were put into run-off in 2004. The net loss from discontinued operations in 2004 included the net adverse impact of prior year accident years on the technical result of USD 506.4 million and an impairment of goodwill of USD 94.0 million.

Our 2005 results were positively impacted by the net favorable impact of prior accident years on the technical result of USD 42.8 million, resulting from net favorable development of prior years’ loss reserves of USD 86.0 million, which were offset by the reductions in premiums and other expenses of USD 43.2 million as well as a satisfactory net investment income. However, our

results were adversely impacted by significant natural catastrophe losses totaling USD 149.2 million from Winter Storm Erwin, the Continental European floods and the US hurricanes, which had an effect of 7.7 points on our 2005 non-life combined ratio of 107.0%.

The table below shows the reconciliation between pre-tax operating income and net income (loss). We use pre-tax operating results to measure the performance of our underlying reinsurance operations, as this measure focuses on the underlying fundamentals of our operations without the influence of realized gains and losses from the sale of investments, or other non-operating items such as goodwill, impairment or restructuring costs.

Year ended December 31, 2006 compared with year ended December 31, 2005

Converium consolidated net income

For the year ended December 31, 2006, we reported net income of USD 57.1 million compared with USD 68.7 million for the same period in 2005.

Converium consolidated income from continuing operations

The Company uses pre-tax operating results to measure the performance of our underlying reinsurance operations without the influence of realized gains and losses from the sale of investments, or other non-operating items such as goodwill, impairment and restructuring costs. We reported a pre-tax operating income from continuing operations of USD 236.4 million for the year ended December 31, 2006 as compared with a pre-tax operating income of USD 52.5 million for the same period in 2005.

We reported net realized gains on investments of USD 18.9 million and USD 31.3 million for the years ended December 31, 2006 and 2005, respectively. Net realized gains for 2006 largely reflect the sale of our holdings in Swiss direct real estate of USD 130.1 million in gross proceeds which generated pre-tax realized gains of USD 18.7 million. Net realized capital gains for 2005 primarily related to the sale of equity securities which were driven by our asset reallocation, which generated proceeds of approximately USD 39.6 million. This positive impact was partially offset by USD 2.4 million related to the partial impairment of our 48% participation in SATEC, which we sold in December 2005.

Converium consolidated (loss) income from discontinued operations

The (loss) income from discontinued operations comprises of the sale of our North American operations (discontinued business), which were sold to the National Indemnity Company. In 2006, loss from discontinued operations was USD 157.9 million, consisting of a total transaction loss of USD 190.1 million which was recognized upon the completion of the sale on December 13, 2006. This was offset by income from operations of discontinued business of USD 32.2 million.

Net income from operations of discontinued business was USD 32.2 million and USD 34.6 million for the years ended December 2006 and 2005, respectively. Income from operations of discontinued business of USD 32.2 million includes commutation gains in connection with the sales transaction of our North American operations. The positive results in 2005 reflect commutations after our North American operations were put into run-off in 2004.

Converium consolidated premiums

For the year ended December 31, 2006, gross premiums written increased by 1.3% and net premiums written increased by 3.9% showing a resilient franchise and visible progress made towards the Company’s turnaround in 2006. Net premiums earned have decreased due to the impact of the ratings downgrades 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%. On a consolidated basis we ceded 6.5% and 8.8% of our gross premiums written for the years ended December 31, 2006 and 2005, respectively.

Converium consolidated net investment income and net realized capital gains (losses)

Investment results are an important part of our overall profitability. Our net investment income increased by USD 2.6 million, or 1.0% for the year ended December 31, 2006 as compared with the same period in 2005. The average total invested assets remained largely unchanged. However, the lower income contribution from the Funds Withheld Asset which was attributable to the declining balance on this asset, was more than offset by higher investment income from short-dated investments reflected in other investment income, due to generally higher yields as a result of an inverted yield curve environment. We paid fees in the amount of USD 8.1 million and USD 9.8 million to our asset managers and custodians for the years ended December 31, 2006 and 2005, respectively, including other investment-related costs. Our average net investment income yield (pre-tax) was 4.2% for the year ended December 31, 2006 as compared with 4.2% for the same period in 2005.

An increasing component of net investment income arises from income received on business written on a funds withheld basis such as certain Lloyd’s transactions. As these assets are reported under funds held by reinsureds and do not form part of the average total invested assets, while the investment income from these funds held by reinsureds is included in our net investment income, there is an increase of 0.2 points for 2006 on the reported average net investment income yield (pre-tax). Excluding this effect, the average net investment income yield (pre-tax) would have been 4.0% and 3.9% for the years ended December 31, 2006 and 2005, respectively.

Our average total investment income yield (pre-tax) was 4.5% for the year ended December 31, 2006 as compared with 4.7% for 2005. Yields are calculated based on the average of beginning and ending total invested asset balances (including cash and cash equivalents). The total investment income yield was slightly lower in 2006 as compared with 2005. In 2006, net realized gains were predominately driven by the sale of Swiss direct real estate holdings, while realized gains on equity securities were offset by realized losses on fixed maturities securities and impairment. In addition, our average total investment income yield (pre-tax) was negatively impacted by USD 11.7 million and USD 9.2 million of impairment charges during 2006 and 2005, respectively. See “Critical accounting policies” for details on our fixed maturities and equity securities impairment policy.

Our average total investment return (pre-tax) was 5.0% for the year ended December 31, 2006 as compared with 4.5% for the same periods in 2005. Our 2006 total investment return was positively impacted by the strong performance of equity securities markets and hedge funds, which also resulted in positive changes in unrealized gains. Additionally, the sale of our North American operations reduced total unrealized losses by USD 26.5 million. This positive development was partially offset by the lower valuation on fixed maturities securities due to yield curve shifts. In 2005, the change in net unrealized gains was driven by a reduction in net unrealized capital gains due to the realization of gains triggered by the sale of equity securities, partially offset by the continued positive development of the stock markets.

Converium consolidated losses, loss expenses and life benefits

Our losses, loss expenses and life benefits incurred decreased for the year ended December 31, 2006 as compared with the same period of 2005 due to a reduction in overall business volume, the absence of any major catastrophic events as well as net favorable development of prior years’ loss reserves. The results for the year ended December 31, 2005 were impacted by the effects of natural catastrophes, which added 7.7 points to the non-life loss ratio.

Development of prior years’ loss reserves: For the year ended December 31, 2006, we reported net favorable development of prior years’ loss reserves of USD 102.8 million. The Standard Property & Casualty Reinsurance segment was positively impacted by net favorable development of prior years’ loss reserves of USD 54.1 million primarily related to the Property and General Third Party Liability lines of business of USD 45.1 million and USD 24.6 million, respectively, partially offset by net adverse development of prior years’ loss reserves related to the Motor line of business of USD 16.5 million. The Specialty Lines segment was positively impacted by net favorable development of prior years’ loss reserves of USD 48.7 million primarily related to the lines of business: Aviation & Space and Engineering of USD 34.9 million and USD 16.2 million, respectively, partially offset by net adverse development of prior years’ loss reserves related to the Professional Liability and other Special Liability line of business of USD 17.6 million.

For the year ended December 31, 2005, we recorded net favorable development of prior years’ loss reserves of USD 86.0 million. The Standard Property & Casualty Reinsurance segment was positively impacted by net favorable development of prior years’ loss reserves of USD 30.7 million primarily related to the Property line of business of USD 73.3 million, partially offset by net adverse development of prior years’ loss reserves within the Motor and General Third Party Liability lines of business of USD 25.0 million and USD 23.4 million, respectively. The Specialty Lines segment was positively impacted by net favorable development of prior years’ loss reserves of USD 55.3 million primarily related to the Aviation & Space line of business of USD 57.5 million.

Impact of property catastrophe losses: The year ended December 31, 2006 exhibited insignificant natural catastrophe activity with total incurred losses of USD 10.5 million. There were no individual large losses, defined as those in excess of USD 10.0 million or more of net incurred losses to us.

The year ended December 31, 2005 exhibited significant natural catastrophe activity and included the following large losses, defined as those in excess of USD 10.0 million or more of net incurred losses:


(USD millions)
Winter Storm Erwin			32.5
Continental European Floods			24.8
Hurricane Katrina			33.2
Hurricane Rita			14.1
Hurricane Wilma			44.6
Total			149.2

Guaranteed Minimum Death Benefit (GMDB) business: For the years ended December 31, 2006 and 2005, there were no additional reserving actions required for the GMDB book of business. As a result of the positive performance of the US stock markets, GMDB’s net amount at risk further decreased to USD 353.9 million at December 31, 2006 from USD 478.2 million at December 31, 2005.

September 11th terrorist attacks: The September 11th terrorist attacks in the United States represented one of the largest loss events in the insurance industry’s history. In 2001, we recorded gross losses and loss expenses of USD 692.9 million arising out of the terrorist attacks (including losses from our subsequently sold North American operations). These losses are capped through an agreement with ZFS. Our recorded losses and loss expenses, net of retrocessional recoveries and the cap from ZFS through its subsidiaries, were reduced from USD 289.2 million to USD 231.0 million, following the sale of our North American operations. We will be exposed to the risk of non-payment of ZFS’ units and we are exposed to credit risk from these subsidiaries of ZFS. We are not exposed to potential non-payments by retrocessionaires for these events in excess of the cap. In 2006, 2005 and 2004, there was no additional development in net reserves for the September 11th terrorist attacks.

Asbestos and environmental exposures: As of December 31, 2006 and 2005, we had reserves for environmental impairment liability and asbestos-related claims of USD 49.2 million, respectively, for each year. Our survival ratio (calculated as the ratio of reserves held, including IBNR, over claims paid over the average of the last three years) for asbestos and environmental reserves was 13.8 years at December 31, 2006 and 14.1 years at December 31, 2005.

Converium consolidated acquisition costs

Acquisition costs primarily relate to commissions on treaty and individual risk business. For the year ended December 31, 2006 our acquisition costs decreased as compared with the same period of 2005 primarily as a result of the reduction of our overall business volume. Our non-life acquisition costs ratio increased for the year ended December 31, 2006 primarily driven by a relatively low acquisition cost ratio in 2005 due to the receipt of reinsurance premiums to close (“RITC”) on our Lloyd’s participations on which there were no acquisition costs.

Converium consolidated operating and administration expenses

Operating and administration expenses decreased for the year ended December 31, 2006 as compared with the same period in 2005 resulting from the 2005 cost management measures. The decrease in administration costs reflects lower average staffing levels, the non-recurrence of the expenses associated with staff retention plans in 2005, the closure of some of our smaller offices in 2005 as well as the full amortization of some of our internal software systems in 2005. Accordingly, the non-life administration expense ratio decreased for the year ended December 31, 2006 as compared with the same period of 2005.

Converium consolidated other loss

Other loss was USD 0.5 million for the year ended December 31, 2006 as compared with USD 21.9 million for the same period in 2005. Other loss in 2006 includes increased interest income from business written on a funds held basis and lower costs of USD 19.9 million incurred from our Lloyd’s participations compared with USD 24.0 million in 2005. Additionally, 2006 includes an income of USD 5.3 million due to the recovery on a balance previously written off. Other loss for the year ended December 31, 2005 includes a USD 9.0 million charge related to our strategic alliance with MDU, (See Note 17 for further information) and a charge of USD 2.4 million related to our investment in SATEC.

Converium consolidated interest expense, amortization of intangible assets and restructuring costs

Interest expense: Interest expense remained relatively stable for the year ended December 31, 2006 as compared with the same period in 2005. Interest expense primarily includes payment on the Guaranteed Subordinated Notes. See Note 11 to our 2006 consolidated financial statements for additional information on our outstanding debt.

Amortization of intangible assets: There was no amortization of intangible assets for the year ended December 31, 2006 compared with USD 21.5 million same period in 2005. The amortization amount in 2005 relates to the intangible asset for Global Aerospace Underwriting Managers Limited (“GAUM”). For additional information on GAUM see Notes 7 and 17 to our 2006 consolidated financial statements.

Restructuring costs: For the year ended December 31, 2006 we incurred a restructuring benefit of USD 0.2 million due to the release of restructuring accruals as compared with expenses of USD 12.1 million for the same period in 2005. In 2005, the reduction in overall business volume required organizational changes and an adjustment to our global cost base including employee terminations and closure of smaller offices.

Converium consolidated income tax expense

We recorded an income tax expense of USD 40.5 million and USD 16.1 million for the years ended December 31, 2006 and 2005, respectively. Our global effective tax rate for continuing operations was 15.9% for the year ended December 31, 2006 as compared with 32.1% for the same period of 2005. For the year ended December 31, 2006, Converium’s consolidated income tax expense of USD 40.5 million comprised of USD 10.3 million of current income tax expense and USD 30.2 million of deferred income tax expense. The current income tax portion reflects the net tax paying position of some affiliated companies. Due to the establishment of a full valuation allowance in 2004 against existing net deferred tax assets our operations in Switzerland reported no income tax and no deferred income tax expense. For all other jurisdictions the Company applies the annual effective tax rate to calculate the income taxes on a jurisdiction-by-jurisdiction basis.

The 2005 consolidated income tax expense of USD 16.1 million comprised of a current income tax expense of USD 12.0 million and a deferred income tax expense of USD 4.1 million.

Converium consolidated combined ratios

Our non-life combined ratio was 96.3% in 2006 and 107.0% in 2005. The decrease in 2006 of the non-life combined ratio resulted from the absence of any major catastrophic events as well as net favorable impact of prior accident years on the technical result of USD 52.1 million. In 2005, our combined ratio was negatively impacted by the catastrophic losses of the US hurricanes and Continental European floods.

Year ended December 31, 2005 compared with year ended December 31, 2004

Converium consolidated net income (loss)

For the year ended December 31, 2005 we reported a net income of USD 68.7 million compared with a net loss of USD 582.5 million for the same period in 2004.

Converium consolidated income from continuing operations

For the year ended December 31, 2005, we reported income from continuing operations of USD 34.1 million compared with USD 25.6 million for the same period in 2004. Our 2005 results were positively impacted by the net favorable impact of prior accident years on the technical result of USD 42.8 million, resulting from net favorable development of prior years’ loss reserves of USD 86.0 million, which were offset by the reductions in premiums and other expenses of USD 43.2 million as well as a satisfactory net investment income. However, our results were adversely impacted by significant natural catastrophe losses totaling USD 149.2 million from Winter Storm Erwin, the Continental European floods and the US hurricanes, which had an effect of 7.7 points on our 2005 non-life combined ratio of 107.0%.

We reported a pre-tax operating income from continuing operations of USD 52.5 million for the year ended December 31, 2005 as compared with a pre-tax operating loss of USD 0.1 million for the same period in 2004.

We reported net realized gains on investments of USD 31.3 million and USD 31.2 million for the years ended December 31, 2005 and 2004, respectively. The 2005 net realized capital gains primarily resulted from higher realized capital gains on the sale of equity securities offset by higher realized losses on fixed maturity securities in connection with ordinary trading activity. The 2004 net realized capital gains reflected the sales of equity securities to adjust the Company’s asset allocation to reduce investment portfolio risk.

Converium consolidated income (loss) from discontinued operations

Net income from operations of discontinued business was USD 34.6 million for the year ended December 2005 as compared with a net loss of USD 608.1 million for the same period of 2004. The positive results in 2005 reflect commutations after our North American operations were put into run-off in 2004. The net loss from discontinued operations in 2004 included the net adverse impact of prior year accident years on the technical result of USD 506.4 million and an impairment of goodwill of USD 94.0 million

Converium consolidated premiums

For the year ended December 31, 2005, gross premiums written decreased by 44.0%, net premiums written decreased by 45.2% and net premiums earned decreased by 27.2% primarily due to the ratings downgrades which occurred in 2004.

For the year ended December 31, 2005, net premiums written in Standard Property & Casualty Reinsurance decreased by USD 638.4 million, or 46.3%, Specialty Lines decreased by USD 827.6 million, or 52.9% and net premiums written in the Life & Health Reinsurance segment decreased by USD 6.8 million, or 2.2%. On a consolidated basis we ceded 8.8% and 6.8% of our gross premiums written for the years ended December 31, 2005 and 2004, respectively.

Net premiums earned for the year ended December 31, 2005 decreased at a slower rate than the corresponding net premiums written as premiums are still being earned from business written in prior underwriting years.

Converium consolidated net investment income and net realized capital gains (losses)

Our net investment income increased by USD 30.3 million, or 13.3% for the year ended December 31, 2005 as compared with the same period in 2004. The increase largely resulted from growth in total invested assets during 2005, and a reallocation from equity securities into income generating fixed maturities securities. We paid fees in the amount of USD 9.8 million and USD 11.6 million to

our asset managers and custodians for the years ended December 31, 2005 and 2004, respectively, including other investment-related costs. Our average net investment income yield (pre-tax) was 4.2% for the year ended December 31, 2005 as compared with 3.9% for the same periods in 2004.

An increasing component of net investment income arises from income received on business written on a funds withheld basis such as certain Lloyd’s transactions. These assets are reported under funds held by reinsureds and do not form part of the average total invested assets, while the investment income from these funds held by reinsureds is included in our net investment income. Excluding this effect, the average net investment income yield (pre-tax) would have been 3.9% and 3.7% for the years ended December 31, 2005 and 2004, respectively.

Our average total investment income yield (pre-tax) was 4.7% for the year ended December 31, 2005 as compared with 4.5% for 2004. Yields are calculated based on the average of beginning and ending total invested asset balances (including cash and cash equivalents). The 2005 and 2004 yields were positively impacted by realized gains resulting from the sale of equity securities to adjust our asset allocation in order to reduce investment portfolio risks. In addition, our average total investment income yield (pre-tax) was negatively impacted by USD 9.2 million and USD 6.2 million of impairment charges during 2005 and 2004, respectively. See “Critical accounting policies” for details on our fixed maturities and equity securities impairment policy.

Our average total investment return (pre-tax) was 4.5% for the year ended December 31, 2005 as compared with 4.6% for the same period in 2004. In 2005, the change in net unrealized gains was driven by a reduction in net unrealized capital gains due to the realization of gains triggered by the sale of equity securities, partially offset by the continued positive development of the stock markets.

Converium consolidated losses, loss expenses and life benefits

Our losses, loss expenses and life benefits incurred decreased for the year ended December 31, 2005 as compared with the same period of 2004 due to a reduction in overall business volume as well as net favorable development of prior years’ loss reserves. This decrease was partially offset by the effects of natural catastrophes, which added 7.7 points to the non-life loss ratio. The results for the year ended December 31, 2004 were similarly impacted by natural catastrophes which added 3.5 points to the non-life loss ratio as well as net adverse development of prior years’ loss reserves.

Development of prior years’ loss reserves: For the year ended December 31, 2005, we recorded net favorable development of prior years’ loss reserves of USD 86.0 million. The Standard Property & Casualty Reinsurance segment was positively impacted by net favorable development of prior years’ loss reserves of USD 30.7 million primarily related to the Property line of business of USD 73.3 million, partially offset by net adverse development of prior years’ loss reserves within the Motor and General Third Party Liability lines of business of USD 25.0 million and USD 23.4 million, respectively. The Specialty Lines segment was positively impacted by net favorable development of prior years’ loss reserves of USD 55.3 million primarily related to the Aviation & Space line of business of USD 57.5 million.

For the year ended December 31, 2004, we recorded net adverse development of prior years’ loss reserves of USD 72.8 million. The Standard Property & Casualty Reinsurance segment was negatively impacted by net adverse development of prior years’ loss reserves of USD 11.3 million primarily related to adverse development within the Motor line of business of USD 78.7 million, which was partially offset by net favorable development of prior years’ loss reserves related to the Property line of business of USD 77.8 million. The Specialty Lines segment was negatively impacted by net adverse development of prior years’ loss reserves of USD 61.5 million primarily related to adverse developments of the Professional Liability and other Special Liability and Engineering lines of business of USD 116.1 million and USD 13.7 million, respectively, partially offset by net favorable development of prior years’ loss reserves related to: Credit & Surety (USD 30.2 million), Aviation & Space (USD 24.6 million) and Workers’ Compensation (USD 16.4 million) lines of business.

Impact of property catastrophe losses: The year ended December 31, 2005 exhibited significant natural catastrophe activity and included the following large losses, defined as those in excess of USD 10.0 million or more of net incurred losses:


(USD millions)
Winter Storm Erwin			32.5
Continental European Floods			24.8
Hurricane Katrina			33.2
Hurricane Rita			14.1
Hurricane Wilma			44.6
Total			149.2

For the non-life business, total net incurred losses from these natural catastrophes were USD 149.2 million which added 7.7 points to the non-life loss ratio of 77.4% for the year ended December 31, 2005. Excluding these events, our non-life loss ratio for the year would have been 69.7%. In 2004, our large natural catastrophe losses included hurricanes in the US and the Caribbean, the Japanese typhoons and the tsunami in the Indian Ocean, with a total net impact of USD 98.4 million. These natural catastrophes added 3.5 points to the non-life loss ratio of 77.6% for the year ended December 31, 2004. Excluding these events, our non-life loss ratio for the year would have been 74.1%.

Based on current estimates of losses from the catastrophic events that occurred during 2005, we did not file a trigger event request regarding our catastrophe protection provided under our Helix 04 Limited counterparty contract in respect of these losses. See Note 10 to our 2006 consolidated financial statements for further information on our Helix catastrophic protection.

Guaranteed Minimum Death Benefit (GMDB) business: For the year ended December 31, 2005 and 2004 there were no additional reserving actions required for the GMDB book of business. As a result of the positive performance of the US stock markets, GMDB’s net amount at risk further decreased to USD 478.2 million at December 31, 2005 from USD 635.5 million at December 31, 2004.

September 11th terrorist attacks: The September 11th terrorist attacks in the United States represented one of the largest loss events in the insurance industry’s history. In 2001, we recorded gross losses and loss expenses of USD 692.9 million arising out of the terrorist attacks (including losses from our subsequently sold North American operations). These losses are capped through an agreement with ZFS. Our recorded losses and loss expenses, net of retrocessional recoveries and the cap from ZFS through its subsidiaries, were reduced from USD 289.2 million to USD 231.0 million, following the sale of our North American operations. We will be exposed to the risk of non-payment of ZFS’ units and we are exposed to credit risk from these subsidiaries of ZFS. We are not exposed to potential non-payments by retrocessionaires for these events in excess of the cap. In December 2004, a federal jury in New York concluded that the two planes that crashed into the World Trade Center during the attacks of September 11th, for insurance purposes, represented two separate attacks. This ruling increased our gross losses and loss expenses by USD 8.7 million, but as our losses are capped at USD 231.0 million by ZFS, as described above, this ruling did not have an effect on our net loss position. In 2005 and 2004, there was no additional development in net reserves for the September 11th terrorist attacks.

Asbestos and environmental exposures: As of December 31, 2005 and 2004, we had reserves for environmental impairment liability and asbestos-related claims of USD 49.2 million for each year. Our survival ratio (calculated as the ratio of reserves held, including IBNR, over claims paid over the average of the last three years) for asbestos and environmental reserves was 14.1 years at December 31, 2005 and 13.6 years at December 31, 2004.

Converium consolidated acquisition costs

Acquisition costs primarily relate to commissions on treaty and individual risk business. For the year ended December 31, 2005 our acquisition costs decreased and our non-life acquisition cost ratio remained relatively stable compared with the same period of 2004. Acquisition costs decreased as a result of the reduction in overall business volume; however premiums were still being earned from business written in prior underwriting years.

Converium consolidated operating and administration expenses

In 2005, operating and administration expenses increased as compared with 2004 primarily due to expenditures relating to the restatement that occurred during 2005/2006 and costs resulting from staff retention plans. The non-life administration expense ratio increased in 2005 as compared with 2004 resulting from the measures referred to above as well as from the sharp decrease in premium volume in 2005 compared with 2004.

Converium consolidated other loss

Other loss for the years ended December 31, 2005 and 2004 was USD 21.9 million and USD 4.7 million, respectively. Other loss for the year ended December 31, 2005 includes a USD 9.0 million charge related to our strategic alliance with MDU, (See note 17 for further information) and a charge of USD 2.4 million related to our investment in SATEC.

Converium consolidated interest expense, goodwill and other intangible assets and restructuring costs

Interest expense: Interest expense remained relatively stable for the year ended December 31, 2005 as compared with the same period in 2004. Interest expense primarily includes payment on the Guaranteed Subordinated Notes. See Note 11 to our 2006 consolidated financial statements for additional information on our outstanding debt.

Amortization of intangible assets: Amortization of other intangible assets was USD 21.5 million for the year ended December 31, 2005 as compared with USD 9.9 million for the same period in 2004. The amortization amounts in 2005 and 2004 relate to the intangible asset for Global Aerospace Underwriting Managers Limited (“GAUM”). The charge for 2005 increased due to the fact that the remaining useful life of the intangible asset was reassessed in the fourth quarter of 2004 to be less than one year which led to the accelerated amortization. For additional information on GAUM see Notes 7 and 17 to our 2006 consolidated financial statements.

Restructuring costs: Converium recorded restructuring costs of USD 12.1 million for the year ended December 31, 2005 compared with USD 0.2 million for the same period of 2004. In 2005, the reduction in overall business volume required organizational changes and an adjustment to our global cost base including employee terminations and closure of smaller offices.

Converium consolidated income tax (expense) benefit

We recorded an income tax expense of USD 16.1 million for the year ended December 31, 2005 compared with an income tax benefit USD 4.6 million in 2004. Our global effective tax rate for continuing operations was 32.1% for the year ended December 31, 2005 as compared with (21.9)% for the same period of 2004. For the year ended December 31, 2005, Converium’s consolidated income tax expense of USD 16.1 million comprised of USD 12.0 million of current income tax expense and USD 4.1 million of deferred income tax expense. The current income tax portion reflects the net tax paying position of some affiliated companies.

Converium consolidated combined ratios

Our non-life combined ratio was 107.0% in 2005 and 105.7% in 2004. The increase in the non-life combined ratio resulted from the negative impact on underwriting results of US hurricanes, Continental European floods and increased expenditures relating to the Restatement.

•		The recognition of net favorable impact of prior accident years on the technical result of USD 38.6 million in 2006, resulting from net positive development of prior years’ loss reserves of USD 54.1 million, offset by reductions in premiums and other expenses of USD 15.5 million.

		The net favorable development of prior years’ loss reserves of USD 54.1 million in 2006 was primarily related to the Property and General Third Party Liability lines of business of USD 45.1 million and USD 24.6 million, respectively, partially offset by net adverse development of prior years’ loss reserves within the Motor line of business of USD 16.5 million.

•		A strong underwriting result within the property catastrophe and non-catastrophe book of business due to the absence of any major catastrophe losses in 2006.

•		In 2005, segment income was impacted by a number of large natural catastrophes. The Standard Property & Casualty segment experienced a total net impact of USD 78.4 million in losses from hurricanes in the United States (Hurricane Katrina: USD 25.6 million, Hurricane Rita: USD 11.2 million and Hurricane Wilma: USD 41.6 million).

		In addition, in 2005, the continental European floods in Switzerland, Germany, Austria and Romania and Winter Storm Erwin resulted in net pre-tax losses of USD 24.8 million and USD 32.5 million, respectively. The overall pre-tax effect from the natural catastrophes mentioned above was USD 135.7 million.

•		In 2005, offsetting these catastrophes, we recorded a net favorable impact of prior accident years on the technical result of USD 19.7 million, resulting from net favorable development of prior accident years’ loss reserves of USD 30.7 million offset by reductions in premiums and other expenses of USD 11.0 million.

		The net favorable development of prior years’ loss reserves of USD 30.7 million was primarily related to the Property line of business of USD 73.3 million, partially offset by net adverse development of prior years’ loss reserves within the Motor and General Third Party Liability lines of business of USD 25.0 million and USD 23.4 million, respectively.

Standard Property & Casualty Reinsurance premiums

For the year ended December 31, 2006, gross premiums written increased by 10.9% to USD 890.6 million, net premiums written increased by 10.5% to USD 816.9 million and net premiums earned decreased by 11.9% to USD 775.6 million. The decrease of net premiums earned in 2006 reflects the impact of the ratings downgrades in 2004 with significantly lower earned premiums from prior underwriting years.

For the year ended December 31, 2006, the increase in net premiums written in the Standard Property & Casualty Reinsurance segment by line of business included:

•		Property increased by 10.5% or USD 41.1 million to USD 431.7 million, primarily due to increased business; and

•		General Third Party Liability increased by 56.6% or USD 83.0 million to USD 229.7 million, reflecting additional Lloyd’s business as well as revisions of premium estimates in 2005.

These increases were partially offset by a decrease in the Motor line of business by 24.0% or USD 45.3 million to USD 143.1 million, reflecting this years’ closing of the 2003 Lloyd’s underwriting year as well as a decrease in the Personal accident (assumed from non-life insurers) by 6.8% or USD 0.9 million to USD 12.4 million.

This was partially offset by net adverse development of prior years’ loss reserves within the Motor line of business of USD 16.5 million.

In 2006, losses and loss expenses incurred decreased due to the absence of any major catastrophe losses in 2006.

In 2005, the Standard Property & Casualty Reinsurance segment was impacted by a number of large natural catastrophes.

The overall pre-tax effect from the natural catastrophes mentioned above was USD 135.7 million.

Slightly offsetting the aforementioned items was net favorable development of prior years’ loss reserves of USD 30.7 million which was primarily related to the Property line of business of USD 73.3 million, partially offset by net adverse development of prior years’ loss reserves within the Motor and General Third Party Liability lines of business of USD 25.0 million and USD 23.4 million, respectively.

The acquisition cost ratio was 25.2% in 2006 as compared with 20.6% for the same period of 2005. The increase is mainly driven by a relatively low acquisition cost ratio in 2005 due to the receipt of reinsurance premiums to close (“RITC”) on our Lloyd’s participations on which there were no acquisition costs.

Standard Property & Casualty Reinsurance operating and administration expenses

Operating and administration expenses remained flat at USD 43.9 million in 2006 while the administration expense ratio decreased from 5.9% in 2005 to 5.4% in 2006 due to the increase in net premiums written.

•		Property (decreased by 25.8% or USD 135.8 million to USD 390.6 million), primarily due to the rating downgrades in 2004;

•		Personal accident (assumed from non-life insurers) (decreased by 61.4% or USD 21.2 million to USD 13.3 million), primarily as a result of the cancellation or non-renewal of business and reduced shares in current business due to the ratings downgrades in 2004.

Year ended December 31, 2006 compared with year ended December 31, 2005

Specialty Lines segment income

Specialty Lines reported segment income of USD 98.9 million and USD 108.9 million in 2006 and 2005, respectively.

• The large decrease of net premiums earned in 2006 reflects the impact of the ratings downgrades in 2004 with significantly lower earned premiums from prior underwriting years.

• Offsetting the decrease in segment income in 2006 was the recognition of net favorable impact of prior accident years on the technical result of USD 13.5 million, resulting from net favorable development of prior years’ loss reserves of USD 48.7 million, offset by reductions in premiums and other expenses of USD 35.2 million.

The net favorable development of prior years’ loss reserves of USD 48.7 million in 2006 primarily related to the lines of business: Aviation & Space and Engineering of USD 34.9 million and USD 16.2 million, respectively, partially offset by net adverse development of prior years’ loss reserves related to the Professional Liability and other Special Liability line of business of USD 17.6 million.

• In 2005, we recorded a net favorable impact of prior accident years on the technical result of USD 23.1 million, resulting from net favorable development of prior years’ loss reserves of USD 55.3 million offset by reductions in premiums and other expenses of USD 32.2 million.

The net favorable development of prior years’ loss reserves of USD 55.3 million primarily related to the Aviation & Space line of business of USD 57.5 million.

•		Marine & Energy decreased by 9.2% or USD 5.9 million to USD 58.1 million.

For the year ended December 31, 2006, these decreases were partially offset by an increase in net premiums written in the Professional Liability and other Special Liability line of business by 5.2% or USD 14.8 million to USD 297.6 million due to our Lloyd’s participations partially offset by the non-renewal of US casualty business. Furthermore, the Agribusiness line of business increased by 1.1% or USD 0.4 million to USD 37.1 million due to our decision to expand our business written in Europe.

Specialty Lines net investment income and net realized capital gains (losses)

In 2005, the segment recorded net favorable development of prior years’ loss reserves of USD 55.3 million primarily related to the

Aviation & Space line of business of USD 57.5 million.

Specialty Lines acquisition costs

Acquisition costs decreased USD 71.4 million, or 27.1%, in 2006 due to the lower volume of business. The acquisition cost ratio increased for the year ended December 31, 2006 from 24.9% to 26.6% primarily due to an additional fronting commission for the GAUM business in relation to the ratings downgrades in 2004.

Specialty Lines Operating and administration expenses

Year ended December 31, 2005 compared with year ended December 31, 2004

Specialty Lines segment income (loss)

Specialty Lines reported segment income of USD 108.9 million in 2005 versus a segment loss of USD 13.4 million in 2004. The results for the Specialty Lines segment are reflective of the overall reduction in business volume as a result of the ratings downgrades that occurred in 2004. In addition to the overall reduction in business volume, the segment income was primarily affected by the following:

•

In 2005, the Specialty Lines segment recorded a net favorable impact of prior accident years on the technical result of USD 23.1 million, resulting from net favorable development of prior accident years’ loss reserves of USD 55.3 million offset by reductions in premiums and other expenses of USD 32.2 million.

The net favorable development of prior years’ loss reserves of USD 55.3 million primarily related to the Aviation & Space line of business of USD 57.5 million.

•

Slightly offsetting the increase in segment income in 2005 was the net impact of losses arising from Hurricanes Katrina, Rita and Wilma within the United States in the amount of USD 13.5 million.

•

In 2004, we recorded a net adverse impact of prior accident years on the technical results in the amount of USD 69.7 million, resulting from net adverse development of prior accident years’ loss reserves of USD 61.5 million, and reductions in premium, related losses and acquisition costs of net USD 8.2 million for the year ended December 31, 2004.

The net adverse development of prior years’ loss reserves of USD 61.5 million primarily related to adverse developments of the Professional Liability and other Special Liability and Engineering lines of business of USD 116.1 million and USD 13.7 million, respectively, partially offset by net favorable development of prior years’ loss reserves related to: Credit & Surety (USD 30.2 million), Aviation & Space (USD 24.6 million) and Workers’ Compensation (USD 16.4 million) lines of business.

Specialty Lines premiums

For the year ended December 31, 2005, gross premiums written decreased by 49.7% to USD 833.1 million, net premiums written decreased by 52.9% to USD 737.7 million and net premiums earned decreased by 23.7% to USD 1,059.2 million. Premium volume for the year ended December 31, 2005 was impacted by the ratings downgrades that occurred in 2004, which resulted in clients canceling their business or reducing their shares with us. In 2004, premium volume was impacted by clients exercising their rights of special termination under various reinsurance contracts, which resulted in a reduction of estimated ultimate premium in the second half of 2004. In addition to the reductions triggered by special termination clauses, the decrease of the Specialty Lines segment’s net premiums written was further affected by adjustments of ultimate premium estimates due to the implementation of enhanced procedures for establishing written premium estimates throughout 2004.

For the year ended December 31, 2005, the reduction in net premiums written in the Specialty Line segment by line of business included:

•

Aviation & Space (decreased by 40.2% or USD 162.7 million to USD 241.8 million);

•

Credit & Surety (decreased by 71.4% or USD 145.9 million to USD 58.4 million);

•

Professional Liability and other Special Liability (decreased by 35.2% or USD 153.7 million to USD 282.8 million);

•

Engineering (decreased by 41.6% or USD 46.7 million to USD 65.5 million);

•

Marine & Energy (decreased by 22.4% or USD 18.5 million to USD 64.0 million); and

•

Workers’ Compensation (decreased by 103.7% or USD 325.4 million to USD (11.5) million); which in addition to the reduction caused by the ratings downgrades was further impacted by a reduction in premium estimates.

For the year ended December 31, 2005, these decreases were partially offset by an increase in net premiums written in the Agribusiness line of business, which increased by 221.9% or USD 25.3 million to USD 36.7 million. This reflected the decision to write this business out of Converium AG, Zurich and to grow the business written in Europe.

Specialty Lines net investment income and net realized capital gains (losses)

Specialty Lines reported net investment income and net realized capital gains of USD 140.5 million for the year ended December 31, 2005, an increase of USD 5.4 million, or 4.0%, compared with net investment income and net realized capital gains of USD 135.1 million for the same period in 2004.

For 2004, the segment recorded adverse development of prior years’ loss reserves of USD 61.5 million primarily related to Professional Liability and other Special Liability and Engineering lines of business in the amounts of USD 116.1 million and USD 13.7 million, respectively. These adverse developments were partially offset by net favorable development of prior years’ loss reserves related to the Credit & Surety, Aviation & Space and Workers’ Compensation lines of business in the amounts of USD 30.2 million, USD 24.6 million and USD 16.4 million, respectively.

The loss ratio was 72.9% in 2005 as compared with 83.2% in 2004, a decrease of 10.3 percentage points.

Specialty Lines acquisition costs

Acquisition costs decreased by USD 64.3 million, or 19.6%, in 2005 due to the lower volume of business. The acquisition costs ratio increased for the year ended December 31, 2005 from 23.6% in 2004 to 24.9% in 2005 due to the additional fronting commission for the GAUM business because of the ratings downgrades in 2004.

Specialty Lines operating and administration expenses

Operating and administration expenses increased by USD 1.2 million or 2.3% to USD 54.5 million in 2005 compared with USD 53.3 million in 2004, however the administration expense ratio increased by 4.0 points to 7.4% as a result of the reduced premium volume in 2005 versus 2004.

Specialty Lines combined ratios

The Specialty Lines combined ratio was 105.2% and 110.2% for the years ended December 31, 2005 and 2004, respectively. The decrease in the combined ratio in 2005 resulted from the recording of net favorable development of prior years’ loss reserves, which led to a reduction of 10.3 points in the loss ratio of 72.9% as compared with 2004. This positive trend was partially offset by an increased administration expense ratio of 7.4% for the year ended December 31, 2005 as compared with 2004.

Life & Health Reinsurance segment income

Life & Health Reinsurance reported segment income of USD 23.5 million and 17.6 million for the years ended December 31, 2006 and 2005, respectively. Segment income is comprised of technical results, less other income (loss), total investment results and other operating and administration expenses.

Although there was a slight decrease in our overall business volume, the total results exhibit the segment’s ability to retain business despite the effects of the ratings downgrades that occurred in 2004. The segment’s positive performance in 2006 was primarily attributable to new, and the expansion of existing reinsurance transactions, particularly within Continental Europe.

The technical result for the year ended December 31, 2006 was USD 16.3 million as compared with USD 14.2 million for the same period of 2005. Technical result is defined as net premiums earned minus losses, loss expenses and life benefits minus acquisition costs plus other technical income (mainly technical interest).

The increase in the technical result in 2006 was primarily attributable to our European and Middle East markets, where we were able to increase our business with current and new cedents.

For the years ended December 2006 and 2005 there were no additional reserve actions required for our Guaranteed Minimum Death Benefit (GMDB) book of business.

Life & Health Reinsurance premiums

For the year ended December 31, 2006, gross premiums written decreased by 1.7% to USD 313.3 million, net premiums written decreased by 0.2% to USD 305.7 million and net premiums earned decreased by 0.8% to USD 312.4 million. Net premiums written for the Life & Disability

line of business increased by 5.2% or USD 12.3 million, compared with 2005, which was primarily driven by new business within our European market. The Accident & Health line of business decreased by 18.3% or USD 13.0 million, compared with 2005, which was mainly due to non-renewal of unprofitable treaties within our European market. This decrease was partially offset by growth within our Middle East market.

Life & Health Reinsurance net investment income and net realized capital gains (losses)

Life & Health Reinsurance reported net investment income and net realized capital gains of USD 29.2 million for the year ended December 31, 2006 compared with net investment income and net realized capital gains of USD 28.7 million for the same period of 2005. The investment results were positively impacted by the disposal of Swiss direct real estate holdings, while realized gains on equity securities were largely offset by realized losses on fixed maturities securities and impairment postings.

Life & Health Reinsurance losses, loss expenses and life benefits

Life & Health Reinsurance had losses, loss expenses and life benefits incurred of USD 212.4 million, a decrease of USD 5.6 million, or 2.6%, in 2006. This decrease was mainly due to the non-renewal of unprofitable treaties within the Accident & Health line of business in our European markets.

Life & Health Reinsurance acquisition costs

Acquisition costs increased by USD 1.8 million, or 2.0%, to USD 94.1 million for the year ended December 31, 2006 as compared with USD 92.3 million for 2005 as a result of new reinsurance transactions in Continental Europe, which carry higher acquisition costs in the early years of a contract. The acquisition cost ratio was 30.1% in 2006 and 29.3% in 2005.

Life & Health Reinsurance operating and administration expenses

Operating and administration expenses decreased USD 4.0 million, or 25.6%, in 2006. The life administration expense ratio was 3.8% in 2006 as compared with 5.1% in 2005.

Year ended December 31, 2005 compared with year ended December 31, 2004

Life & Health Reinsurance segment income

Life & Health Reinsurance reported segment income of USD 17.6 million and USD 16.4 million for the years ended December 31, 2005 and 2004, respectively.

Although there was a slight decrease in our overall business volume, the total Life & Health Reinsurance results exhibit the segment’s ability to retain business despite the effects of the ratings downgrades that occurred in 2004.

Technical result for the year ended December 31, 2005 was USD 14.2 million as compared with USD 16.4 million for the same period of 2004. Technical result is defined as net premiums earned minus losses, loss expenses and life benefits minus acquisition costs plus other technical income (mainly interest on deposits).

The decrease in the technical result in 2005 was primarily attributable to the cancellation of existing reinsurance transactions in Latin America as well as the establishment of an additional provision for the Asian tsunami of USD 0.7 million.

For the years ended December 2005 and 2004 there were no additional reserve actions required for our Guaranteed Minimum Death Benefit (GMDB) book.

Life & Health Reinsurance premiums

For the year ended December 31, 2005, gross premiums written decreased by USD 9.1 million or 2.8% to USD 318.8 million, net premiums written decreased by USD 6.8 million or 2.2% to USD 306.4 million and net premiums earned decreased by USD 3.9 million or 1.2% to USD 314.8 million. The reduction in net premiums written was primarily within the health line of business which decreased by 30.8% or USD 10.3 million to USD 23.1 million. The decline was attributable to the cancellation of existing reinsurance transactions in the Middle East in 2004 and a reduction of business in Latin America due to our ratings downgrades and the decision

to close down our life operations in Buenos Aires. Additionally, premiums decreased in our non-active North American markets, as expected, both in the health line of business as well as the life line of business. These decreases were partially offset by new business written in the Middle East and Continental Europe as well as the expansion of existing reinsurance transactions in 2005.

Life & Health Reinsurance net investment income and net realized capital gains (losses)

Life & Health Reinsurance reported net investment income and net realized capital gains of USD 28.7 million for the year ended December 31, 2005 compared with net investment income and net realized capital losses of USD 19.2 million for the same period of 2004. The investment results were positively impacted by realized gains resulting from the sale of equity securities to adjust our asset allocation in order to reduce investment portfolio risks.

Life & Health Reinsurance losses, loss expenses and life benefits

Life & Health Reinsurance had losses, loss expenses and life benefits incurred of USD 218.0 million, a decrease of USD 19.3 million, or 8.1%, in 2005. This decrease was mainly due to the cancellation of existing reinsurance transactions in the Middle East in 2004 as well as reduced business in our inactive North American markets.

Life & Health Reinsurance acquisition costs

Acquisition costs increased USD 19.8 million, or 27.3%, to USD 92.3 million for the year ended December 31, 2005 as compared with USD 72.5 million for 2004. This increase is related to the increase in financing business which shows high acquisition costs in the first year of the contract. The acquisition costs ratio was 29.3% in 2005 and 22.7 % in 2004.

Life & Health Reinsurance operating and administration expenses

Operating and administration expenses increased USD 3.9 million, or 33.3%, in 2005. The life administration expense ratio was 5.1% in 2005 as compared with 3.7% in 2004.

Corporate Center

The table below presents information regarding the results of operations of our Corporate Center for the years ended December 31, 2006, 2005 and 2004.

Corporate Center operating and administration expenses

The Corporate Center costs increased for the year ended December 31, 2005 as compared with the same period of 2004 due to increased legal, audit and consulting fees of approximately USD 15.0 million, primarily relating to the internal review and the Restatement.

B. LIQUIDITY AND CAPITAL RESOURCES

We operate a treasury function responsible for managing our banking relationships, capital raising activities, including equity and debt issues, our overall cash, cash pooling and liquidity positions and the payment of internal and external dividends. Individual subsidiaries are responsible for managing local cash and liquidity positions, including the repayment of debt.

In the event of local short-term cash requirements, internal loans are available, subject to certain required approvals based on amount.

Liquidity requirements

Our principal cash requirements are for paying reinsurance and insurance claims, which could periodically include significant cash requirements related to catastrophic events, for servicing debt, investment in businesses, payments for our business operations, capital expenditures, servicing retrocessional arrangements and payment of dividends to shareholders.

Letters of credit

As of December 31, 2006, Converium had total letters of credit outstanding of USD 1,974.5 million, which included USD 1,898.0 million secured and USD 76.5 million unsecured.

There are financial covenants attached to the syndicated letter of credit facility including restrictions on total borrowing up to 35% of tangible net worth (shareholders’ equity less goodwill) and tangible net worth must remain greater than USD 1,237.5 million at all times. Converium pays commission fees on outstanding letters of credit, which are distributed to the facility banks and can only be impacted by a change in the Company’s credit rating. The maximum amount of this fee is 0.50%.

On August 11, 2006, Converium secured an uncollateralized USD 250.0 million letter of credit facility from a leading European banking group, at market conditions. It will be primarily used to support third party claims related to the underwriting business. As of December 31, 2006, the total outstanding letter of credit under this facility was USD 76.5 million.

As of December 31, 2006, Converium reported total investments including cash and cash equivalents and excluding the Funds Withheld Asset of USD 5,457.7 million. Of this total, USD 1,973.5 million was pledged as collateral relating to outstanding letters of credit.

Interest on debt and short-term borrowings was USD 16.7 million, USD 17.2 million and USD 18.7 million for the years ended December 31, 2006, 2005 and 2004, respectively. We had no scheduled debt repayments in 2006, 2005 or 2004. The carrying value of our outstanding debt was USD 194.1 million at December 31, 2006, USD 391.2 million at December 31, 2005 and USD 391.1 million at December 31, 2004.

Liquidity sources

Our principal liquidity sources consist of premiums, fees, investment income, proceeds from the sale and maturity of investment securities and borrowings. Our business units pay reinsurance and insurance claims and benefits and operating expenses predominantly from their own cash resources. As a reinsurer, our future cash flows are inherently difficult to predict. We do not expect the Funds Withheld Asset to have a material impact on our liquidity, as we will not be required to access our own liquidity sources for claims under the Quota Share Retrocession Agreement. Under the Quota Share Retrocession Agreement, Zurich Insurance Company (“ZIC”) and Zurich International Bermuda Ltd. (“ZIB”) have the right to prepay to us, in whole or in part, the balance of the Funds Withheld Asset. For more detail on cash flows see “— Capital requirements”.

Asset/Liability Management

The use of asset/liability management, or ALM, is a key tool in managing the assets part of our business and the determination of our capital requirements. Through the use of ALM, we principally manage our long-term market risks and we seek to understand and manage the dynamic interactions between our assets and liabilities. We utilize and continually develop firm-wide ALM processes and models to manage our aggregate financial risks and the correlation between financial risks and underwriting risks. The primary goal of our ALM procedures is to match, in terms of timing and currency, anticipated claims payments to our cedents with investment income and repayments generated by our invested assets and to improve our understanding of the correlation between financial risks and underwriting risks. Because fixed income securities generally provide more stable investment income than equity securities, the majority of our investments are in fixed income instruments. Although our ALM techniques are based on theoretical and empirical models and can lead to incorrect assumptions, we believe that the careful use of these ALM techniques leads to a better understanding of the risk/return profile inherent in our assets and liabilities and is therefore an important element of our risk, capital allocation and investment management process. Our principal ALM techniques include cash flow analysis, scenario testing and stochastic modeling. See “Item 4. — Information on the Company — B. Business Overview – Investments” for additional information on our invested asset base.

Dividends from subsidiaries

As a holding company, Converium Holding AG relies in large part on cash dividends and other permitted payments from its subsidiaries to make principal and interest payments on debt, to pay other outstanding obligations and to pay dividends to shareholders. Converium Holding AG paid a gross dividend of CHF 0.10 for the business year 2005 and CHF 0.20 for the business year 2006 to its shareholders. The dividend payments were made on April 18, 2006 and May 15, 2007 respectively. Converium is subject to legal restrictions on the amount of dividends it may pay to its shareholders. Similarly, the company laws of countries in which our entities operate may restrict the amount of dividends payable by such entities to their parent companies. In addition, the ability of our entities to pay dividends may be restricted or influenced by minimum capital and solvency requirements that are imposed by regulators in the countries in which the entities operate. Dividend payments from Converium AG to Converium Holding AG may be subject to regulatory review. (see Notes 15 and 21 to our 2006 consolidated financial statements).

Debt outstanding

As of December 31, 2006, we had total debt outstanding with a principal amount of USD 200.0 million and a carrying amount of USD 194.1 million.

This debt is comprised of USD 200.0 million principal amount of non-convertible, unsecured, guaranteed subordinated notes, issued by Converium Finance S.A. in December 2002, which are irrevocably and unconditionally guaranteed on a subordinated basis by each of Converium Holding AG and Converium AG. These notes mature in full on December 23, 2032 and bear interest at the rate of 8.25%. The first call date is December 24, 2007. (See Notes 11 and 15 to our 2006 consolidated financial statements). We had no scheduled debt repayments in 2006, 2005, or 2004.

Capital requirements

As of December 31, 2006, we had total shareholders’ equity of USD 1,846.0 million (USD 12.63 per share) compared with USD 1,653.4 million (USD 11.29 per share) as of December 31, 2005, an increase of USD 192.6 million (USD 1.34 per share). The increase primarily reflects net income of USD 57.1 million, which includes the loss on disposal of our North American operations, an increase in cumulative translation adjustments of USD 95.0 million as well as an increase in net unrealized gains (losses) on

investments of USD 55.3 million. In 2006, a dividend in the amount of CHF 0.10 per share was paid to shareholders or an aggregate of USD 11.7 million. Book value is calculated using shares outstanding at the end of the period.

Cash and cash equivalents, beginning of period		647.3		680.9		280.8
Cash and cash equivalents, end of period		633.1		647.3		680.9

Cash and cash equivalents decreased by USD 14.2 million to USD 633.1 million as of December 31, 2006 from USD 647.3 million as of December 31, 2005. Our cash position primarily decreased due to the sale of our North American operations with a negative impact on cash and cash equivalents of USD 273.8 million.

Our cash flows from operating activities result principally from premiums, collections on losses recoverable and investment income, net of paid losses, acquisition costs and administration expenses. For the year ended December 31, 2006, the Company generated positive cash inflow from operating activities mainly due to the solid business result of 2006. This was offset by cash outflows due to commutation payments from our former North American operations during the first half of 2006 as well as claims payments which included losses from major catastrophes incurred in prior years. The significant decrease of cash flow from operating activities to USD 399.9 million cash outflow for the year ended December 31, 2005 compared with an inflow of USD 358.7 million in 2004 was due to the reduction in overall business volume and commutation payments during 2005. Cash provided for these measures was mainly obtained through the liquidation of investments.

The net cash outflow used in investing activities of USD 42.8 million for the year ended December 31, 2006 reflects the impact of the sale of the North American Operations in the fourth quarter 2006, a net outflow of USD 273.8 million (proceeds less cash sold). The proceeds of the sale of Swiss direct real estate held in 2006 provided net cash inflow of USD 130.1 million.

Cash used in financing activities for the year ended December 31, 2006 was USD 91.6 million and included cash payments of USD 76.2 million related to deposit liabilities compared with USD 36.8 million cash used in financing activities in 2005. For the year ended December 31, 2004, cash provided by financing activities was USD 347.8 million which was primarily driven by the proceeds, net of related expenses, received from the Rights Offering that occurred in October 2004, offset by the payment of dividends to shareholders.

As of December 31, 2006, Converium Holding AG had cash and cash equivalents of USD 18.4 million. Significant cash needs in 2007 will be payments of the 2006 dividend to shareholders and interest payments to Converium Finance S.A., Luxembourg of approximately USD 10.5 million, related to the note payable with a principle of USD 150.0 million. The cash needs are primarily financed through existing cash funds held at Converium Holding AG, inter-company loan receivables from Converium AG, Switzerland, Converium IP Management AG, Switzerland and Converium Finance Ltd., Bermuda.

We believe that our capital, liquidity and borrowing ability are sufficient to support our business and meet our present liquidity requirements.

New accounting standards

The following new standards have been or will be required to be adopted by Converium in the future:

SFAS 155, “Accounting for Certain Hybrid Instruments”

In February 2006, the FASB issued SFAS 155, “Accounting for Certain Hybrid Instruments"(SFAS 155). This Statement amends SFAS 133,“Accounting for Derivative Instruments and Hedging Activities and SFAS 140,“Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities”. The Standard allows financial instruments that have embedded derivatives to be accounted for as a whole (eliminating the need to bifurcate the derivative from its host contract) if the holder elects to account for the investment on a fair value basis. SFAS 155 also clarifies and amends certain other provisions in SFAS 133 and SFAS 140. This Statement is effective for all financial instruments acquired or issued in fiscal years beginning after September 15, 2006. This

guidance is currently not expected to have a material impact on the Company’s results of operations and financial position.

SFAS 157 “Fair Value Measurements”

In September 2006, the FASB issued SFAS 157, “Fair Value Measurements” (SFAS 157). This standard provides enhanced guidance for using fair value to measure assets and liabilities. SFAS 157 is effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The Company is currently in the process of evaluating the effect that the adoption of SFAS 157 will have on its results of operations and financial position.

The Company adopted SFAS 158 on December 31, 2006. See Note 1 (q) Employee benefits to our 2006 consolidated financial statements.

SFAS 159, “The Fair Value Option for Financial Assets and Financial Liabilities”

In February 2007, the FASB issued SFAS 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (SFAS 159). The fair value option established by SFAS 159 permits all entities to choose to measure eligible items at fair value at specified election dates. A company shall report unrealized gains and losses on items for which the fair value option has been elected in earnings at each subsequent reporting date. The fair value option may generally be applied instrument by instrument, is irrevocable, and, is applied only to entire instruments and not to portions of instruments. SFAS 159 becomes effective for financial years beginning after November 15, 2007. Converium is in the process of determining the impact of SFAS 159.

FASB Interpretation No. FIN 48,“Accounting for Uncertainty in Income Taxes–an interpretation of FASB Statement No. 109”

In June 2006, the FASB issued FASB Interpretation No. (FIN) 48, “Accounting for Uncertainty in Income Taxes”, which clarifies the accounting for uncertainty in income taxes recognized in financial statements in accordance with SFAS No. 109, “Accounting for Income Taxes.” FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This Interpretation requires that the impact of a tax position is recognized and measured in the consolidated financial statements, if that position is more likely than not of being sustained in an audit, based on the technical merits of the position. FIN 48 also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods and disclosure. The new guidance is applicable for periods beginning after December 15, 2006 and is not expected to have a material impact on the Company’s financial condition or results of operations in 2007.

FASB Staff Position (“FSP”) SFAS 123(R)-5 “Amendment of FASB Staff Position SFAS 123(R)-1”

In October 2006, the FASB issued FSP SFAS 123(R)-5, “Amendment of FASB Staff Position SFAS 123(R)-1”, which addresses whether a modification of an instrument in connection with an equity restructuring should be considered a modification for the purposes of applying SFAS 123(R)-1. This FSP becomes effective for fiscal years beginning after October 10, 2006 and is currently not expected to have a material impact on the Company’s results of operations and financial position.

FASB Staff Position (“FSP”) FIN 46(R)-6 “Determining the Variability to be Considered in Applying FASB Interpretation No. 46(R)”

In April 2006, the FASB issued FSP FIN 46(R)-6, "Determining the Variability to be Considered in Applying FASB Interpretation No. 46(R)”. This FSP addresses how an entity should determine the variability when applying FIN 46(R). The variability will determine if an entity is a variable interest entity as well as the amounts of any expected losses or residual returns. This FSP is effective for reporting periods commencing after July 15, 2006. The Company is currently in the process of evaluating the impact that this FSP will have on its results of operations and financial position.

SEC Staff Accounting Bulletin 108 (SAB 108) – “Considering the Effects of Prior Year Misstatements when Qualifying Misstatements in Current Year Financial Statements”

In September 2006, the SEC staff issued SAB 108, "Considering the Effects of Prior Year Misstatements when Qualifying Misstatements in Current Year Financial Statements". SAB 108 was issued to eliminate the diversity of practice surrounding how public companies quantify financial statement misstatements. At December 31, 2006, the date of required adoption, this new guidance did not have a material impact on the results of operations and financial positions.

ITEM 6. DIRECTORS, SENIOR MANAGEMENT AND EMPLOYEES

A. DIRECTORS AND SENIOR MANAGEMENT

Board of Directors

Converium’s global strategy is set by its Board of Directors, the body with ultimate responsibility for Converium’s policies and management, including investment, treasury, solvency and liquidity policies. The Board of Directors consists of no less than four and no more than nine members. Currently it comprises five. With wide-ranging experience in the reinsurance sector, this group represents an appropriate mix of skills for the effective governance of a major international reinsurance organization. The Board of Directors oversees Converium’s affairs and offers regular directives to the Global Executive Committee. All Board members except Derrell J. Hendrix (whose term expired and he did not stand for re-election at the AGM on May 10, 2007), are non-executive and independent. None of the Board members have ever held an executive position within Converium or any of its subsidiaries. No interlocking directorships exist between the Board members of Converium and board members of any other company. Each Board member must disclose any material relationship with the company or potential conflict of interests, annually, in a special statement which is evaluated by the Audit Committee. Following this evaluation the Board of Directors affirmatively determines which members of the Board of Directors qualify as independent.

The composition of the Board of Directors includes a cross section of geography and professional experience. The members of the Board of Directors are elected for a term of office of not more than three years, after which they become eligible for re-election. In case of the election of a substitute, the new Board member finishes the term of office of the predecessor.

The Board of Directors is headed by the Chairman or, in his absence, by the Vice Chairman. The Board of Directors meets as often as circumstances require, but at least four times per year. In 2006 the Board of Directors met seven times physically and held five further meetings by way of conference call. The average attendance of Board members at Board and Committee meetings was over 90%.

Meetings generally last one day, with Committee meetings preceding Board meetings. Agendas are set by the Chairman of the Board of Directors or the pertinent Chairman of the Committee respectively. At each of its meetings the Board of Directors must be informed, through formal reports by the Chief Executive Officer (CEO) and the members of the Global Executive Committee (GEC), about the course of the business and the activity of the business segments and the GEC. In case of important business incidents, the Board of Directors must be informed without delay. Furthermore, each Board member receives appropriate information with respect to any matter to be considered by the Board of Directors. For financial reporting purposes, this includes an appropriate quarterly

reporting package comprising financial and investment information including consolidated financial accounts of Converium and its business segments. The CEO, the Chief Financial Officer (CFO) and the General Legal Counsel attend Board meetings on a regular basis. Members of the GEC and other executives attend meetings at the Chairman’s invitation. In addition, conference calls and meetings between Board members and members of the GEC are held to resolve formal matters or to exchange information. The Board of Directors performs an annual self-evaluation and sets its objectives based upon this evaluation. Annually it reviews the performance of the CEO and approves his or her objectives.

The Head of Internal Audit reports directly to the Audit Committee, and the Board meets regularly with Converium’s external auditors, and, as may be necessary, with outside consultants to review the business, better understand all laws and policies, and support the management in meeting requirements and expectations.

Compensation of senior management

Global Executive Committee remuneration

The Nomination and Remuneration Committee sets compensation levels for members of the GEC and proposes to the Board the remuneration of the Chief Executive Officer.

Compensation for each member of the GEC consists of a base salary and an incentive component based on Converium’s and the individual’s performance. The incentive component may vary highly from year to year depending on the corporate and personal achievement of the incentive award targets set annually by the Board of Directors.

The Nomination and Remuneration Committee determines the awards paid out to the GEC. The performance-based incentive component consists of the Annual Incentive Plan (AIP) and the Long-Term Incentive Plan (LTIP). In 2006 a minimum of 25% of the performance-based compensation paid under the AIP was paid in the form of Converium shares. As of 2007, the AIP will be paid out in cash only. The LTIP is part of Converium’s executive share ownership program and designed to align the interests of management closely with those of shareholders as well as to encourage stock ownership. In 2006, 50% of the award paid out under the LTIP was delivered in Converium shares and the other 50% of the award was paid out in non-qualified options. As of 2007 LTIP awards will be made with Converium shares only. These shares will vest after three years (cliff vesting).

Total aggregate compensation of all officers of the GEC in 2006 was USD 6.4 million (CHF 8.0 million). This total includes base salary and cash awards made under short- and long-term incentive plans paid during 2006, and the estimated value of other compensation-related items.

Two members of the GEC, Peter Boller and Terry G.Clarke, gave up their functions during 2006. In line with contractual obligations a total of USD 1.0 million (CHF 1.2 million) (including share awards) was paid to these individuals in 2006. No further payments were made to former members of the GEC in 2006.

GEC members held shares and options at the end of December 2006. Some were awarded under Converium’s AIP and LTIP, some converted to Converium shares and options from employee participation plans of Converium’s former parent, Zurich Financial Services, and others bought in conjunction with the Initial Public Offering or otherwise. No options are held by closely linked parties. GEC members participate in local pension plans. More information about Converium’s employee participation and pension plans is contained in notes 13 and 14 to the 2006 financial statements.

Upon a take-over situation all outstanding options and shares granted to the members of the GEC or other staff would vest immediately. Furthermore in such a situation the employment agreements with the members of the GEC provide for a severance payment in the amount of an annual base salary and 100% of the GEC member’s personal Annual Incentive Plan target in case the employment agreement is terminated by the employer (or under certain circumstances – i.e. in case of a constructive termination – by the GEC member) within 12 months after the completion of a take-over situation.

As part of the transaction agreement between Converium and SCOR S.A. (dated May 9, 2007), Converium AG will enter into termination agreements with Inga Beale and Paolo De Martin. Subject to the settlement of the tender offer the agreements terminate the employment agreement between Converium AG and Inga Beale respectively Paolo De Martin by December 31, 2007. As part of the agreement Converium will pay USD 3.4 million (CHF 4.2 million) to Inga Beale and USD 2.0 million (CHF 2.5 million) to Paolo De Martin releasing the Company from all obligations as of December 31, 2007 (including severance payments mentioned in the paragraph above).

Employee incentive and benefit plans

An important component of our compensation program is the provision of additional employee benefits designed to encourage our employees to pursue our annual and longer-term objectives. These incentive plans are designed to attract, retain and motivate executives and staff to achieve performance-related targets and align the interests of our employees with those of our shareholders.

Accordingly, we have established incentive programs where benefits are linked to both corporate, financial and business as well as individual performance targets. Additionally, our long-term incentive plans include equity participation and stock option plans or their equivalent. These plans took effect at the time of the Formation Transactions. Their terms are summarized below.

Share Plan

Converium has adopted a standard stock option plan for our non-US employees and an omnibus share plan for our US employees. These arrangements, which we refer to collectively as the “Share Plan”, establish the framework by which we grant awards to selected executives, employees and consultants of Converium and its subsidiaries. In addition, our subsidiaries are able to establish so-called “sub-plans” under the Share Plan in order to address local law and competitive practice concerns. However, we intend that the terms of these sub-plans will be substantially the same as the Share Plan.

The shares required under the plans are purchased in the open market.

Awards are granted at the discretion of our Remuneration Committee. Generally, the size of a participant’s award is based on the level of responsibility and position, market conditions and the extent of the executive or employee’s prior participation in the Converium plans described above.

New options granted have an exercise price equal to the market value of the shares or ADSs on date of grant, 25% vest immediately on the grant date and 25% each year thereafter and will have a 10.5 year term. For 2001 and 2002, most restricted shares granted vest in their entirety after six years, subject to acceleration after year three based on the achievement of certain performance objectives. Beginning in 2003, most restricted shares granted vest ratably over three years. Shares also vest upon retirement.

In connection with these plans, we incurred approximately USD 4.2 million of incentive compensation expense in 2006.

Grants to Global Executive Committee

Global Executive Committee members held shares and options at the end of December 2006. Some were awarded under Converium’s AIP and LTIP, some converted to Converium shares and options from employee participation plans of Converium’s former parent, Zurich Financial Services, and others bought in conjunction with the Initial Public Offering or otherwise. No options are held by closely related parties.

(1)		Shares granted in 2006 include shares awarded under the LTIP, which are subjected to various vesting schedules, and shares purchased through the employee stock purchase plan. During the vesting period there is a risk of forfeiture in case of any termination of the employment relationship.

(2)		Includes only vested shares (includes shares held by closely related parties).

(3)		Options have an exercise price equal to the market value of the shares on date of grant, 25% vest immediately on the grant date and 25% each year thereafter, and have a 10.5-year term. The strike price of all options outstanding prior to the Rights Offering in 2004 was adjusted in 2005 in order to account for the dilution of the value of the options as a result of the Rights Offering. The reduction in the strike price maintains the same Black-Scholes-Merton value of the option before and after the Rights Offering and does not reflect any other decrease in the share price.

(4)		Resigned from the Global Executive committee on February 1, 2007.

(5)		Resigned from the Global Executive committee on July 1, 2006.

(6)		Will resign from the Global Executive committee by June 30, 2007.

As of the date of this Form 20-F filing, none of the members of Global Executive Committee beneficially owns more than 1% of our shares.

Annual Incentive Plan

We have also established annual incentive plans, whose primary purpose is to provide direct annual financial incentive to employees who achieve corporate performance goals established under our annual operating plan. Our subsidiaries are able to establish separate plans to address local law and competitive practice concerns, but we intend that the terms will be substantially the same and refer to

these plans collectively as the “Annual Incentive Plan”. Employees are eligible for target awards under the Annual Incentive Plan (AIP) ranging from 5% to 200% of base salary. The size of the target award is determined by the employee’s position and competitive data for similar positions at peer companies. We set performance goals for participating employees and, in keeping with our performance-based philosophy, the resulting awards decrease or increase substantially if our actual corporate performance fails to meet or exceeds target levels. The awards may range from below or above the target amounts. The performance goals include both financial and non-financial measures.

In 2006 participants in our Annual Incentive Plan were permitted to defer a portion of their bonus into restricted shares or units under our “Annual Incentive Deferral Plan”. Unless otherwise determined by Converium, employees who determined to do so received a 25% premium, paid in restricted shares or bookkeeping units representing shares, on the amount deferred that will vest in their entirety in three years. Effective 2007, the AIP will be paid out in cash only. Accordingly, there are no entitlements to premium shares for awards paid in 2007 and after.

Upon a take-over situation an accelerated vesting of premium shares (which were granted in 2005 and 2006) will occur. The rules for the cash payout for 2007 remain unchanged.

Employee Stock Purchase Plan

Converium adopted an Employee Stock Purchase Plan (the “ESPP”) on January 1, 2002. The ESPP has two offering periods beginning January 1 and July 1 of each year. Substantially all employees meeting specified service requirements are eligible to participate in the ESPP. Participants may contribute between 1% and 15% of base salary towards the purchase of Converium Holding AG shares, up to certain limits. Employees who enroll in the ESPP purchase Converium Holding AG shares at 85% of the lower of the stock’s fair market value on the first or last day of the offering period. Effective January 1, 2007, we adopted changes to the ESPP. Under the new plan rules substantially all employees may contribute once a year up to 15% of their base salary towards the purchase of Converium Holding AG shares. The purchase price is set at 75% of the closing price of the stock fair market value on the grant date (usually the date of the AGM of Converium). Theses shares have a selling restriction of 1 year which would be lifted in case of a take-over situation.

Employee retention plan

In September 2004, Converium adopted a retention plan for certain of its key employees in order to ensure the successful continuation of business operations and the orderly run-off of its formerly owned North American operations. The total cost of the program was USD 28.8 million, over a 3 year period with the last installment paid in January 2006. The continuing operations portion was USD 7.1 million and USD 11.6 million for 2005 and 2004, respectively. Additionally included in the results for discontinued operations for 2006 is an accrual of USD 0.8 million for payments to certain North American employees following the finalization of the sale of the North American operations in December 2006. The liability for the balance of North American employees’ retention plans is covered by Berkshire Hathaway in accordance with the sale agreement.

Long Term Incentive Plan (“LTIP”)

The LTIP is designed to align the interests of management closely with those of shareholders and to encourage share ownership. LTIP awards are made to senior employees and are awarded in a combination of 50% Converium shares and 50% options to purchase shares in Converium Holding AG. Shares vest ratably over three years. Options are issued with an exercise price equal to the market value of the shares on the grant date. 25% of the options vest immediately on the grant date and 25% vest each year thereafter or upon retirement. The options expire 10.5 years after the date of grant. As of 2007 LTIP awards will be made with Converium shares only. These shares will vest after three years (cliff vesting). Upon a take-over situation all outstanding options and shares granted to LTIP participants would vest immediately. Converium intends to settle its obligations from the accelerated vesting in connection with the SCOR Tender Offer in the form of cash payment payable on the first day of the additional acceptance period. The Company is currently assessing the impact on the statement of income of the respective accounting period.

Executive IPO Option Plan

In connection with the Formation Transactions, Converium granted certain executives options to purchase shares in Converium Holding AG (the “Executive IPO Option Plan”). Under the Executive IPO Option Plan, 420,000 options to purchase shares in Converium Holding AG were awarded. The exercise prices were equal to the market value of the shares or ADSs on the grant date. Executive IPO Options are now fully vested and expire 10.5 years after the date of grant.

For further information on our share-based incentive plans, see Note 14 to our 2006 consolidated financial statements.

C. BOARD PRACTICES

Board committees

The Board of Directors has three Committees, which meet in conjunction with or prior to Board meetings, as necessary, and regularly report and submit proposals to the Board of Directors. Each Committee has a Chairman who directs the meetings according to a set agenda, and a secretary, currently the General Legal Counsel.

The Nomination and Remuneration Committee

The Nomination and Remuneration Committee comprises of at least three Board members and currently comprises four. Only independent Directors are eligible to serve on the Nomination and Remuneration Committee. In order to qualify as independent, a member may not accept any consulting, advisory or compensatory fee, other than his/her Board compensation, from the Company. In addition, a Nomination and Remuneration Committee member may not be a person affiliated with the Company or any of its subsidiaries. Standing invitees are the Chief Executive Officer (CEO) and the Chief Human Resources Officer.

The Nomination and Remuneration Committee proposes to the Board of Directors the appointment of members of the Board of Directors, of the Committees of the Board of Directors and of their chairpersons, the Chairman and Vice Chairman of the Board of Directors, the CEO and the members of the Global Executive Committee. They appoint and dismiss the General Legal Counsel (if not a member of the Global Executive Committee), the Head of Internal Audit and any outside directors of Converium companies. Furthermore the Nomination and Remuneration Committee sets the compensation levels for the GEC (except the CEO) and the Head of Internal Audit, and proposes to the Board of Directors the overall remuneration for the CEO and for each of the members of the Board of Directors. They elaborate the principles of compensation, of the incentive schemes, of bonus payments for the employees and submit them to the Board of Directors for approval. Their tasks and responsibilities also include the review of overall compensation above USD 750,000, the acceptance of Executive and Board memberships in third companies by GEC members, contracts between Converium and any GEC members or any of their family members, not at arm’s length and any guidelines relating to the granting of loans by Converium to Converium employees. In 2006 the Remuneration and Nomination Committee met seven times physically.

The Finance and Risk Committee

The Finance and Risk Committee comprises of at least three Board members and currently comprises four. A majority of the members has to be financially literate. Standing invitees are the Chief Executive Officer, the Chief Financial Officer, the Chief Risk Officer, the Chief Investment Officer and the Head of Financial & Rating Models.

The Finance and Risk Committee approves external providers of asset management services and capital increases in subsidiaries between USD 5 million and USD 20 million. It initiates and reviews the Credit Rating strategy of Converium and reviews the planned tactical asset allocation, group-wide cash management, financial performance of the asset management operations and the use of derivatives. The tasks and responsibilities also include the proposal to the Board of the accounting standards framework, the annual budget and financial plans, investment and treasury policy, solvency and liquidity planning, strategic asset allocation, tax planning, the allocation of expenses to be charged to the Corporate Center, capital increases and the use of contingent or authorized capital, and share purchase program for Converium other than in connection with the operation of employee compensation plans, as well as exchange listings and de-listings.

The Finance and Risk Committee liaises with Converium’s Risk Management functions to review and identify Converium’s areas of greatest risk and their efficient management. It assesses and submits to the Board of Directors for approval Converium’s Risk Management Policy and the overall risk appetite for the most significant risk activities. It is responsible for the review and approval of the yearly risk management report, Converium’s risk assessment catalogue and action plans. In 2006 the Finance and Risk Committee held four meetings.

The Audit Committee

The Audit Committee comprises at least three Board members and currently comprises four. Only independent directors are eligible to serve on the Audit Committee. In order to qualify as independent, a member may not accept any consulting, advisory or compensatory fee from the Company. In addition, an Audit Committee member may not be a person affiliated with the Company or any of its subsidiaries. Standing invitees are the Chief Executive Officer, Chief Financial Officer, Chief Risk Officer, the Head of Internal Audit, the Global Financial Controller and the external auditor.

The Audit Committee recommends the appointment and dismissal of the external auditors to the Board of Directors, overviews the external auditors, supervises and reviews the effectiveness of the compliance policy including all compliance matters with material

financial/reputational consequences, approves any public disclosure in conjunction with Converium’s financial results or any other disclosure with significant impact for Converium’s business, cooperates with the internal and external auditors in order to identify any possible deficiencies in the internal control mechanisms of Converium and discusses the annual audit report with the external and internal auditors as well as with management.

The tasks and responsibilities of the Audit Committee include the review of any financial statements, the approval of the quarterly and half-year results (except 4th quarter), review and assessment of any significant accounting and reporting issues as well as the review of Converium’s year-end results, reserve policy and dividend policy. The Audit Committee is briefed on how Converium’s management develops preliminary external announcements and interim financial information and assesses the fairness of such preliminary and interim statements on the basis of Converium’s applicable accounting principles. In 2006 the Audit Committee met nine times physically and held one meeting by way of conference call.

The Audit Committee is supported in its supervisory task by Group Internal Audit (GIA). GIA assists the Audit Committee in providing an independent, objective assurance and consulting activities that are designed to add value and improve an organization’s operations. GIA helps the organization in accomplishing its objectives by bringing a systematic approach for evaluating and improving the effectiveness of risk management, internal controls and governance processes.

GIA reports directly to the Audit Committee and covers all operations of Converium worldwide. GIA has unrestricted access to all relevant documents and information. The Audit Committee also approves the audit plans and the budgets of GIA.

In 2006, GIA conducted various regular audit projects and executed the “Management Testing of the Internal Controls over Financial Reporting” (ICOFR) required by the Sarbanes-Oxley Section 404 on behalf of management.

Group Internal Audit is compliant with the Standards for Professional Practice of Internal Auditing set out by the Institute of Internal Auditors. This was confirmed by an external quality assessment review performed by KPMG.

The objectives of GIA, which were formally approved by the Audit Committee, are:

	•		To evaluate the reliability and controls for the financial and risk reporting systems and to provide reasonable assurance that material errors and irregularities will be detected and that corrective actions are implemented on a timely basis.

	•		To evaluate the reliability and integrity of financial and operational information.

	•		To evaluate compliance with policies, plans, procedures, regulations, laws and contracts.

	•		To safeguard the company assets.

	•		To evaluate and promote efficient use of resources.

	•		To review operations to ascertain whether results are consistent with established goals and whether the operations are being carried out as planned.

	•		To review specific operations at the request of the Audit Committee (or management as appropriate).

The areas of responsibility of the Board of Directors, its Committees and the Global Executive Committee as well as the other corporate bodies are defined in the Organizational By-laws of Converium Holding AG, which are available on the internet at www.converium.com.

At the annual general meeting of Converium Holding AG on April 11, 2006 G. C. Parker stepped down from the Board of Directors and Audit Committee. Mr Harald Wiedmann has been elected as the new audit committee financial expert.

Indemnification of officers and directors

We maintain customary directors’ and officers’ insurance for our directors and officers.

In addition, we have entered into agreements with certain of our directors pursuant to which we have agreed to indemnify each such director for legal expenses incurred in conjunction with his or her professional liability to shareholders, bondholders, creditors or others caused by actions or omissions by such person in his or her capacity as a director, except where such professional liability was caused by the intent or negligence of such director and provided that (i) such indemnification is in our best interest considering the facts and circumstances and (ii) such legal expenses are not covered by our existing Directors and Officers Liability Insurance or are otherwise reimbursable to such director by the plaintiff.

New committee structure

In its Constituent Meeting of April 11, 2006, the newly composed Board of Directors resolved a revised structure of the Board Committees which comprised an amalgamation of the Nomination and Remuneration Committees into the Nomination and Remuneration Committee, combining the functions of the previous two committees into one; the renaming of the Finance Committee into Finance and Risk Committee and allocating certain risk and risk management related responsibilities to this committee and an amendment of the functions of the Audit Committee to reflect recent development in the corporate governance area, in particular but not limited to the development in conjunction with Sarbanes-Oxley. The revised Organizational By-laws can be accessed through Converium’s website (www.converium.com).

D. EMPLOYEES

As of December 31, 2006, Converium employed 532 people globally, including 319 at our offices in Switzerland, 142 at our offices in Germany, 24 in other European countries, 29 in the Asia-Pacific region and 42 in other regions.

A relatively small number of our employees are represented by unions. We have not experienced any material work stoppages in recent years and we believe that our relations with our employees are excellent.

The following table shows the number of employees by geographic location and category of activity:

(1)		The substantial decrease in the Finance function results from the shift of employees to the Chief Operating Officer function, which was established on July 1, 2006.

E. SHARE OWNERSHIP

As of the date of this annual report, none of the members of our Board of Directors or Global Executive Committee beneficially owns more than 1% of our shares. In addition, none of the members of our Board of Directors or Global Executive Committee have an ownership interest in a company that is a major client or broker of Converium. For an explanation of shares and options, see “Item 6. — Directors, Senior Management and Employees — B. Compensation”.

ITEM 7. MAJOR SHAREHOLDERS AND RELATED PARTY TRANSACTIONS

A. MAJOR SHAREHOLDERS

As of May 31, 2007, 87,942,160 shares were registered in our share register. These shares were owned by 4,315 shareholders, of which 3,992 were private individuals holding 3.61% of total outstanding shares, 84 were foundations and pension funds holding 1.79% of total outstanding shares and 239 were other legal entities holding 54.55% of total outstanding shares.

As of May 31, 2007, 14 holders with registered addresses in the United States, including nominees with registered addresses in the United States, held 3,565,327 of our registered shares and 7 holders with registered addresses in the United States, including nominees with registered addresses in the United States, held 5,741,564 ADSs. Brokers and other nominees hold certain of our registered shares and ADSs. In addition, some holders of our

100

registered shares have not or may not register their holdings. Consequently, the above figures may not state the actual number of US beneficial holders or the number of registered shares or ADSs beneficially held by persons in the United States.

As of the date of this annual report, and in accordance with the notification requirements as set by the SWX Swiss Stock Exchange, the following are direct or indirect owners of 5% or more of our outstanding shares:

•

SCOR S.A., Paris, France: 32.9% (date of notification February 19, 2007). SCOR is a French reinsurer that operates in over 120 countries.

Our major shareholders hold the same voting rights as all other shareholders.

On April 5, 2007, SCOR formally commenced a then-unsolicited tender offer for Converium. On May 9, 2007, the Company and SCOR entered into the SCOR Transaction Agreement pursuant to which the Company agreed that its Board of Directors would unanimously support and recommend the SCOR Tender Offer. If SCOR is successful and the SCOR Tender Offer is consummated, it may result in a change in control of the Company under Swiss law.

B. RELATED PARTY TRANSACTIONS

There were no unpaid loans, including guarantee commitments, granted to the Converium directors and members of the Converium Global Executive Committee as of December 31, 2006.

GAUM

In 2003, Converium finalized an agreement to acquire a 25% stake in GAUM, a leading international commercial and general aviation underwriting agency, as a part of its strategy to strengthen its long-term position in the Aviation and Space line of business. At that same time, Converium entered into a pool members’ agreement under which it became a member of the aviation and aerospace pools run by GAUM and its subsidiary, Associated Aviation Underwriters Inc.

In February 2004, Converium AG acquired a further 5.1% stake in GAUM from RSA increasing its overall stake to 30.1%.

For the 2006, 2005 and 2004 underwriting years, Converium has committed 27.25% of the overall pool’s capacity of the aviation risks managed by GAUM. Gross premiums assumed through the pools managed by GAUM were USD 230.8 million, USD 206.2 million and USD 289.0 million for 2006, 2005 and 2004 respectively.

In the light of changing business circumstances associated with Converium’s S&P rating downgrade in the third quarter of 2004, Converium entered into fronting agreements with Munich Re and National Indemnity in order to support and sustain the aviation business from GAUM. These fronting agreements initially extended to September 30, 2005, however Converium has subsequently entered into a further series of fronting agreements with National Indemnity Company and Munich Re under similar terms and conditions which ensured Converium’s continued participation in the pool of GAUM through December 31, 2006. Converium also entered into a further agreement to extend the fronting agreement with the two counterparties until December 31, 2007 in respect of United States and Canadian sourced business and in respect of business sourced from the rest of the world.

The pool members’ agreement with respect to GAUM provides that if a member of the pool has its financial strength rating downgraded below BBB+ by Standard & Poor’s Rating Service it may be served with a notice terminating its membership in the pool upon approval by the committee of representatives of the pool. Converium expects that continuation of its membership at its current rating is likely to be conditional upon its entering fronting arrangements acceptable to other pool members in a timely fashion and thereafter maintaining such arrangements. If Converium’s membership were to be reduced to less than a 5% share, it would not be permitted to participate in future pool business and would have to collateralize by way of a letter of credit its obligations under the business written by the pool in its name prior to its termination. If Converium’s pool membership were terminated, it may also be required to sell its 30.1% stake in GAUM.

At December 31, 2006 and December 31, 2005, the current carried value of goodwill associated with the 30.1% stake in GAUM was GBP 13.1 million (USD 23.4 million) and GBP 13.2 million (USD 23.6 million).

See Note 7 to our 2006 consolidated financial statements for additional information on GAUM goodwill and intangible assets.

At December 31, 2006 and December 31, 2005 Converium had an outstanding shareholder loan to GAUM of GBP 15.2 million (USD 29.8 million) and GBP 15.2 million (USD 26.1 million) at the respective balance sheet dates.

In May 2007, the Company signed a sales agreement to sell a 2.6% stake in GAUM to Münchner Rückversicherungs-Gesellschaft Aktiengesellschaft in München (“Munich Re”) for a purchase price of USD 2.6 million (at a fixed exchange rate of 1.86 against GBP), the right to part of the RSA Loan for GBP 1.3 million and additional Deferred Consideration of 2.6%. The transaction is subject to approval of the European antitrust authorities.

101

MDU

Converium entered into a strategic alliance with the MDU that resulted in a 49.9% participation in MDUSL. MDUSL distributes medical malpractice insurance policies to the members of the MDU. As a result of the initial FSA approval in respect of general liability business, insurance policies underwritten by Converium Insurance (UK) Ltd were issued to members of the MDU beginning July 1, 2003. These insurance policies replaced policies formerly issued in the United Kingdom by ZFS’ entities, the majority of which were reinsured by Converium. Gross premiums written from MDU were USD 187.6 million, USD 178.6 million and USD 170.9 million for 2006, 2005 and 2004, respectively.

The MDU Shareholders’ Agreement provides that if Converium’s credit rating is lowered by more than seven points, from its initial “A+” rating, by a recognized credit ratings agency, the MDU may serve Converium with a Termination Notice. Within sixty days after service of such termination notice, MDU has the right to purchase Converium’s 49.9% shareholding in MDU Services Ltd. at a price to be mutually agreed upon by the parties, or to be determined by a valuation expert. See Note 7 to our 2006 consolidated financial statements for additional information on MDU.

The current terms of the MDU Shareholders’ Agreement require that Converium will provide a price concession, starting in 2010 and annually thereafter based upon a predetermined formula under which a price concession, which will be equal to 50% of the amount by which the present value profit, of a particular underwriting year, as calculated 10 years after that underwriting year has expired, exceeds a pre-agreed target expected present value profit. Converium has recognized a charge of USD 7.7 million and USD 9.0 million for 2006 and 2005 respectively in other (loss) income reflecting the current view of how the Company will settle this obligation.

At December 31, 2006 and December 31, 2005, the balance sheet obligation included in other liabilities was USD 16.7 million and USD 9.0 million respectively.

SCOR

On February 19, 2007, SCOR publicly announced that it had acquired a 32.9% interest in Converium’s outstanding registered shares, of which 8.3% and 24.6% were acquired through direct market purchases and share purchase agreements, respectively. On April 5, 2007, SCOR formally launched an unsolicited tender offer pursuant to which each of Converium’s registered share were to be exchanged for 0.5 ordinary shares of SCOR and CHF 4. On May 9, 2007, Converium and SCOR entered into the SCOR Transaction Agreement pursuant to which SCOR agreed to increase the consideration payable to holders of Converium’s registered shares to 0.5 new SCOR shares and CHF 5.50 in cash in exchange for each Converium registered share tendered and Converium agreed that its Board of Directors would recommend the SCOR Tender Offer to Converium shareholders. SCOR has further agreed to not to reduce the cash portion of the offer consideration by the Company’s proposed gross dividend of 0.20 CHF per share for the fiscal year ended December 31, 2006. The SCOR Tender Offer is governed by the laws of Switzerland and in case of a successful consummation may result in a change in control of the Company. Other than the Transaction Agreement - see Item 10 C Material Contracts - there are no material transactions with SCOR group.

The business as described under related party transactions contains termination provisions which give the ceding company or counterparty the right of termination in the event of a change in control. Whether a change in control has taken place or not will ordinarily be determined by the legal jurisdiction which governs the individual contract concerned. The exercise of termination provisions following a change in control could have a material adverse impact on our business, operating results and financial conditions.

C. INTERESTS OF EXPERTS AND COUNSEL

Not applicable.

ITEM 8. FINANCIAL INFORMATION

A. CONSOLIDATED STATEMENTS AND OTHER FINANCIAL INFORMATION

Financial statements

See our 2006 consolidated financial statements beginning on page F-1.

Legal proceedings, claims and litigation

Converium Holding AG and its subsidiaries are continuously involved in legal proceedings, claims and litigation arising, for the most part, in the ordinary course of its business operations as a reinsurer. The outcome of such current legal proceedings, claims and litigation could have a material effect on operating results or cash flows when resolved in a future period. However, in the opinion of management, these matters are not material to Converium’s financial position, with the exception of the matters described below:

Canada Life

On December 21, 2001, The Canada Life Assurance Company (“Canada Life”), brought an action against Converium Rückversicherung (Deutschland) AG (“Converium Germany”) in the United States District Court of the Southern District of New York. Canada Life alleged that Converium Germany breached certain quota share retrocession agreements with Canada Life by failing to indemnify its full percentage of Canada Life’s September 11th losses and by failing to post an USD 82.4 million letter of credit for its alleged liability pursuant to the ISA facilities’ underlying agreements. Converium Germany disputed this claim on the grounds that its liability under the pertinent contracts is limited and also raised other contract defenses. After litigation in the federal courts concerning jurisdictional issues, which Canada Life lost, Canada Life agreed to arbitration. The organizational meeting of the arbitrators took place on October 8, 2003. Since then, pursuant to an order by the arbitration panel, Converium Germany obtained a letter of credit of USD 65.97 million to be drawn down upon, if at all, should two of the three arbitrators issue an award in favor of Canada Life. A two-week hearing was conducted in July 2005. The arbitration panel since has rendered a final award in favor of

102

Converium Germany. On May 9, 2006 (and later amended twice), Canada Life brought an action against the umpire of the arbitration panel and Converium Germany in the Ontario, Canada Superior Court of Justice seeking to set aside the final award. Canada Life alleges that the umpire was biased and unable to perform his duties. Canada Life also filed a Verified Petition against Converium Germany in the United States District Court of the District of New Jersey seeking, among other relief, to vacate the final award. Converium Germany recently filed a motion to dismiss the New Jersey action. On December 31, 2006 the letter of credit expired. The trial in the Canadian proceeding is scheduled to commence in September 2007.

Converium Germany disagrees with the factual and legal arguments of both lawsuits and contends that the final award is valid and binding. However, due to the uncertainties inherent in proceedings of this nature, Converium was unable to evaluate the likelihood of an unfavorable outcome or to estimate the amount or range of any potential loss resulting from these lawsuits.

Converium Germany has fully reserved this claim. However, arrangements entered into with ZFS provide for the claim to be covered by the agreed-to cap for September 11th related losses provided to Converium by ZFS in conjunction with Converium’s Initial Public Offering.

Review of certain of Converium’s reinsurance transactions

On March 8, 2005, MBIA issued a press release stating that MBIA’s audit committee undertook an investigation to determine whether there was an oral agreement with MBIA under which MBIA would replace Axa Re Finance as a reinsurer to Converium Reinsurance (North America) Inc. (CRNA), one of our former North American subsidiaries, by no later than October 2005. The press release stated that it appeared likely that MBIA made such an agreement or understanding with Axa Re Finance in 1998. Thereafter, on April 19, 2005, CRNA received subpoenas from the U.S. Securities and Exchange Commission and the Office of the New York Attorney General seeking documents related to certain transactions between CRNA and MBIA. Converium has also received additional inquiries from the Securities and Exchange Commission and other governmental authorities in Europe regarding non-traditional insurance and reinsurance products and/or the restatement of its financial statements. The inquiries are ongoing and Converium is fully cooperating with the governmental authorities.

In view of the industry investigations and the events relating to MBIA described above, Converium engaged independent outside counsel to assist it in a review and analysis of certain of its reinsurance transactions, including the MBIA transactions. The internal review, which was overseen by the Audit Committee, addressed issues arising from the ongoing governmental inquiries and Converium’s own decision to review certain additional items. The internal review involved the assessment of numerous assumed and ceded transactions including structured/finite risk and other reinsurance transactions and encompassed all business units of Converium, a review of hundreds of thousands of e-mails, attachments to e-mails and other documents and interviews of all current members of the Global Executive Committee and the Board of Directors, as well as certain former members of senior management and other employees of Converium. The Audit Committee believes that the scope and process of the internal review has been sufficient to determine whether Converium’s assumed and ceded transactions were improperly accounted for as reinsurance, rather than as deposits. After discussing the findings of Converium’s extensive internal review with independent outside counsel, the Audit Committee determined that certain accounting corrections were appropriate and authorized the Restatement of Converium’s financial statements as of and for the years ended December 31, 2004 through 1998. As part of this process, the Audit Committee has involved its independent group auditors, PricewaterhouseCoopers Ltd. Financial information and for each of the quarters ended March 31, 2003 through June 30, 2005. have also been restated. For further information regarding these accounting adjustments, please refer to Converium’s 2005 Annual Report. (See Note 3 to our 2005 consolidated financial statements on page F-17 to the 2005 20-F filed with the SEC on June 29, 2006) (Additionally, 2002 was further restated as discussed in Note (1) to the 2006 consolidated financial statements on page F-3). Previously published financial statements regarding any of the above periods should no longer be relied upon.

As noted above, Converium is fully cooperating with the governmental authorities and are in the process of sharing the results of our internal review with the relevant authorities. Although the internal review was extensive, the ongoing governmental inquiries, or other developments, could result in further restatements of Converium’s financial results in the future and could have a materially adverse effect on Converium.

Class action lawsuits

103

action lawsuits were brought against the Company and several of its officers and directors in the United States District Court for the Southern District of New York between October 4, 2004 and December 2, 2004 (collectively, the “Federal Actions”).

On December 9, 2004, another securities law class action lawsuit, Rubin v. Converium Holding AG, et al., Index No. 04-117332, was brought against the Company and certain of its officers and directors in the Supreme Court of the State of New York for the County of New York (the “Rubin Action”). The Rubin Action was removed to the United States District Court for the Southern District of New York. Rubin moved to remand his action to state court.

On July 14, 2005, the Court signed an order in the Federal Actions appointing Public Employees’ Retirement System of Mississippi and Avalon Holdings Inc. lead plaintiffs. On September 23, 2005, the lead plaintiffs filed a consolidated amended class action complaint (the “Complaint”) setting forth their claims. The Complaint includes the Louisiana State Employees’ Retirement System as an additional named plaintiff.

The Complaint names as defendants the Company; former directors Terry G. Clarke, Peter C. Colombo, Georg F. Mehl, George G.C. Parker, Derrell J. Hendrix and Anton K. Schnyder; former officers Dirk Lohmann, Martin Kauer and Richard Smith; former director Jürgen Förterer; ZFS; UBS AG; and Merrill Lynch International. The Complaint asserts claims for violations of Section 10(b) and Section 20(a) of the Securities Exchange Act of 1934 and Sections 11, 12 and 15 of the Securities Act of 1933 and alleges, among other things, that the Company misrepresented and omitted material information in various public disclosures during the period from December 11, 2001, through September 2, 2004 because the Company did not establish adequate loss reserves to cover claims by policyholders; that the Company’s announced reserve increases prior to July 20, 2004, were insufficient; and that, as a result of the foregoing, the Company’s earnings and assets were materially overstated. The putative class of plaintiffs on whose behalf these lawsuits have been asserted consists of all buyers of the Company’s stock from December 11, 2001, through and including September 2, 2004. Plaintiffs are seeking unspecified compensatory damages, attorney’s fees, witness fees and expert fees.

On December 23, 2005, the defendants moved to dismiss the Complaint. On February 17, 2006 the lead plaintiffs submitted a memorandum of law in opposition to all defendants’ motions to dismiss the Complaint.

On April 21, 2006, plaintiffs moved for leave of Court to file a proposed Consolidated Second Amended Class Action Complaint, to amend their Complaint to add, among other things, Securities Act claims based on Converium’s March 1, 2006, restatement of its financial accounts from 1998 through 2005.

On November 16, 2006, the Court consolidated all of the actions, including the Rubin action. On November 27, 2006, Rubin’s motion to remand his action to state court was withdrawn. On December 1, 2006, Plaintiffs submitted a proposed Consolidated Second Amended Class Action Complaint as a substitute for the previously proposed Second Amended Class Action Complaint, which made certain changes to the previously proposed Consolidated Second Amended Class Action Complaint.

On December 28, 2006, the Court issued an Opinion and Order granting in part and denying in part defendants’ motions to dismiss the Complaint. The Court dismissed the claims against all defendants alleging violations of Sections 11, 12 and 15 of the Securities Act of 1933 as well as claims asserting violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (the “Exchange Act”) based upon allegations that the Company misrepresented and omitted material information in its December 11, 2001, initial public offering prospectus and registration statement. The Court denied the motion to dismiss those claims against the Company and three of its former officers alleging that those defendants violated Section 10(b) and Section 20(a) of the Exchange Act by misrepresenting and omitting material information in various public disclosures following the Company’s initial public offering. Also on December 28, 2006, the Court denied plaintiffs’ motion to amend their complaint. The Court further ordered that the parties who remain in the actions, including the Company, engage in settlement discussions before a Magistrate Judge. A settlement conference took place before a Magistrate Judge on February 15, 2007 but did not result in a settlement.

On January 12, 2007, plaintiffs filed a motion for reconsideration of the Court’s December 28, 2006 order. The defendants filed an opposition to that motion on February 5, 2007, and plaintiffs filed a reply brief in further support of their motion on February 20, 2007. On April 9, 2007, the Court granted Plaintiffs’ motion for reconsideration in part and denied it in part. The Court granted Plaintiffs’ motion to reconsider its dismissal of Exchange Act claims arising out of the initial public offering. The Court indicated that it will address the other arguments Defendants made to support dismissal of those claims in a forthcoming opinion. The Court denied Plaintiffs’ motion to reconsider the dismissal of the Securities Act claims, as well as denial of their motion to file a Consolidated Second Amended Class Action Complaint.

The consolidated actions are in the discovery phases; thus, the timing and outcome of these matters are not currently predictable. The costs of defending the class action may have a material impact on our operating results in future reporting periods and an unfavorable outcome could have a materially adverse effect on the Company’s financial condition, results of operations and cash flows.

Dividends and dividend policy

The Annual General Meeting of shareholders held in Zug on April 11, 2006 approved the proposal of the Board of Directors to allocate CHF 14,668,946 of available earnings to dividends that resulted in a gross dividend of CHF 0.10 per registered share. The dividend payment was made on April 18, 2006.

For the business year 2006 the Annual General Meeting held in Zurich on May 10, 2007 approved the proposal of the Board of Directors to allocate CHF 29,337,892 of available earnings to dividends that resulted in a gross dividend of CHF 0.20 per registered share. The dividend payment was made on May 15, 2007.

Our dividend policy in future periods will depend on a number of factors including our results of operations, our financial condition, our capital and cash requirements, general business conditions, legal, contractual and regulatory restrictions regarding the payment of dividends by us and other factors. Holders of shares and ADSs with respect to the underlying shares are entitled to receive payment in full of any dividends declared. The Board of Directors pursues a target pay-out ratio of 25-35%.

As a holding company, we are dependent on dividends, and interests from our subsidiaries to pay cash dividends. The payment of dividends by our subsidiaries to their parent companies is restricted by applicable laws and regulations. To the extent our subsidiaries are restricted from paying dividends to Converium Holding AG, we may be unable to pay dividends to our shareholders. For further information on the restrictions on our ability to pay dividends, see Note 21 to our 2006 consolidated financial statements. In addition to the dividend restrictions, Converium AG’s ability to pay dividends may be restricted by certain directions issued by FOPI.

Under Swiss corporate law, we may only pay dividends if we have either sufficient profits available for distribution or if we have sufficient free reserves pursuant to our statutory (non-consolidated) balance sheet and the provisions of Swiss law to allow for distributions from that reserve.

As long as the general reserves amount to less than 20% of our nominal share capital, Swiss corporate law requires at least 5% of our annual net profits to be retained as general reserves. Any net profits remaining after this retention are eligible to be distributed as dividends, subject to approval by our shareholders at a shareholders’ meeting, and our independent group auditors must confirm that a dividend proposal by our Board of Directors complies with our Articles of Incorporation and Swiss law.

B. SIGNIFICANT CHANGES

Except as otherwise disclosed in this annual report, there has been no significant change in our financial position since December 31, 2006.

ITEM 10. ADDITIONAL INFORMATION

A. SHARE CAPITAL

Not applicable.

B. MEMORANDUM AND ARTICLES OF INCORPORATION

See “Description of Shares and Share Capital” in the Registration Statement on Form F-1, file number 333-14106, filed with the SEC under the Securities Act of 1933 on December 10, 2001. The Articles of Incorporation were amended in 2004 and 2006 to reflect the following changes to our issued, authorized and conditional share capital.

Issued share capital

Upon incorporation on June 19, 2001, Converium Holding AG had share capital of CHF 100,000 divided into 10,000 fully paid registered shares with a nominal value of CHF 10 each, all of which were entitled to receive dividends. On September 24, 2001, the Extraordinary General Meeting of the shareholders passed two resolutions to increase the share capital to CHF 400 million, divided into 40 million fully paid registered shares with a nominal value of CHF 10 each, all of which were entitled to receive dividends.

In October 2004, Converium’s share capital was increased by CHF 533,416,225 by issuing 106,683,245 shares at CHF 5 each. The additional shares were issued and Converium’s corresponding capital increase (and reduction of the nominal value) were recorded, in the Commercial Register of the Canton of Zug, Switzerland on October 12, 2004. After the registration of the shares in the Commercial Register of the Canton of Zug, Converium’s issued, outstanding share capital was CHF 733,447,310, divided into 146,689,462 shares with a nominal value of CHF 5.

The Board of Directors proposed to the Annual General Meeting of May 10, 2007 that CHF 2.50 be remitted to the shareholders by way of a reduction of the ordinary share capital from CHF 733,447,310 to CHF 366,723,655 by reducing the par value of registered shares from CHF 5 to CHF 2.50.

The Annual General Meeting did not approve the proposal for the capital reduction for the purpose of a par value repayment to shareholders.

Authorized share capital

At the Annual General Meeting on April 27, 2004, the shareholders resolved to create authorized share capital and amended the Articles of Incorporation, which provides that the Board of Directors is authorized, on or before April 27, 2006, to increase the share capital by the issuance of up to a maximum of four million fully paid-up registered shares each of CHF 10 nominal value amounting to a maximum of CHF 40 million. Subsequent to the reduction of the nominal value of each of Converium’s shares from CHF 10 to CHF 5 as a result of the resolution by the shareholders at the EGM of September 28, 2004, Converium’s authorized capital is now CHF 20,000,000 with the Board being authorized to issue up to four million shares.

At the Annual General Meeting on April 11, 2006 the shareholders resolved to extend the authority of the Board of Directors to increase the share capital until April 11, 2008.

At December 31, 2006, no shares were issued from the authorized share capital.

Contingent share capital

At the Annual General Meeting on April 27, 2004, Converium Holding AG amended its Articles of Incorporation to state that the previously available conditional share capital for use in conjunction with the employee participation plans has been replaced by a conditional share capital for option rights and/or conversion rights for a number of four million shares or CHF 40,000,000 in nominal share capital.

Subsequent to the reduction of the nominal value of each of Converium’s shares in October 2004, its conditional capital is now for a

107

number of four million shares of CHF 5 nominal value each, amounting to a maximum of CHF 20,000,000 pursuant to which up to four million shares can be issued upon exercise of conversion or option rights allotted in connection with bonds and other financial market instruments.

At December 31, 2006, no shares were issued from the contingent share capital.

Information policy

In conjunction with the invitation for the Annual General Meeting, all registered shareholders are provided with an invitation and a summary report on Converium’s financial results for the current financial year. Upon request, a full annual report with the financial statements can be ordered. Additionally, all ADS holders, upon request, receive a copy of the current annual report including financial statements, through their brokers. Furthermore, all financial and other information released by Converium is accessible on Converium’s web page at www.converium.com as well as through the SEC.

Statutory Quorums

According to Article 13 of Converium’s Articles of Incorporation, resolutions at the General Meetings of Shareholders are taken with the majority of votes cast.

In accordance with the provisions of Swiss law (Article 704 Swiss Code of Obligations) Converium’s Articles of Incorporation require two thirds of votes to be represented and the absolute majority of the nominal values of the shares represented is required for resolution on the following:

•		an alteration of the purpose of Converium

•		the creation of super-voting shares

•		restrictions on the transfer of registered shares and the removal of such restrictions as well as restrictions to vote and the removal of such restrictions

•		an authorized or contingent increase of share capital

•		an increase of share capital by conversion of capital surplus, by contribution in kind or for the purpose of an acquisition of assets and the grant of special rights

•		a restriction or exclusion of the subscription right or advance subscription right

•		a change of Converium’s registered office

•		the dissolution of Converium without liquidation

Convocation of the General Meeting of the Shareholders

According to Article 9 of Converium’s Articles of Incorporation, the General Meetings are convened at least 20 days prior to the meetings. This is in accordance with the provision of Swiss company law (Article 700 Code of Obligations).

Article 10 of the Articles of Incorporation provides for shareholders whose combined share holdings represent an aggregate nominal amount of at least CHF one million to be able to demand an item to be included on the agenda of a General Meeting. Such demand must be made at least 45 days prior to the meeting. This is in accordance with the provision of Swiss company law (Article 699 paragraph 2 Code of Obligations).

Registration in the Share Register

The date by which holders of registered shares can be registered in Converium’s share register in connection with attending the General Meeting of shareholders is set by the Board of Directors in its preparatory Board Meeting prior to the General Meeting.

108

For 2007, the date by which a shareholder had to be registered in the share register was May 8, 2007 in order to be invited to the Annual General Meeting of May 10, 2007, at Kongresshaus, Gartensaal, 8002, Switzerland.

Shareholder votes on equity-based compensation plans

The NYSE rules require that shareholders must vote on all equity based compensation plans and any material revisions to the terms of such plans. Converium does not comply with this requirement, as under Swiss Company Law, the approval of compensation plans is not an authority of the General Meeting, but of the Board of Directors. The reason for not providing for approval of equity based compensation plans is the fact that the capital of a Swiss company is determined in the Articles of Incorporation and, therefore, each increase of capital has to be submitted for shareholders’ approval. If equity based compensation plans result in a need for a capital increase, the shareholders’ approval is mandatory. If, however, shares for such plans are purchased in the open market, shareholders do not have the authority to vote.

C. MATERIAL CONTRACTS

The Master Agreement

The Master Agreement set out the overall principles and the rights and obligations of the parties in connection with the Formation Transactions. It also addressed the relationship between Zurich Financial Services and Converium following the Formation Transactions. In particular, the Master Agreement provides for:

•		the separation of substantially all of the third party reinsurance business from the businesses of Zurich Financial Services; and

•		the consolidation of this business under Converium Holding AG.

The third party reinsurance business that has been retained by Zurich Financial Services includes the Zurich Centre Group business as described below and the reinsurance business written by ZIC with inception or renewal dates prior to January 1, 1987.

In the Master Agreement, Zurich Financial Services and Converium made certain representations and warranties with respect to matters including the assets of and titles to the assumed business. In addition, each of Zurich Financial Services and Converium made certain covenants, principally intended to effect our separation from the other businesses of Zurich Financial Services.

Further, each of Zurich Financial Services and Converium agreed, following the completion of the Formation Transactions:

•		to execute the agreements, and to cooperate and act in accordance with the arrangements described below; and

•		not to, except for certain specified exceptions, disclose confidential information of the other party or an entity of such party’s group which is not known to third parties but which is known by the parties due to the fact that the parties were previously part of the same group of companies or as a result of the Formation Transactions contemplated by the Master Agreement.

In addition, the Master Agreement provided that we bear up to a maximum of USD 50 million of the costs and expenses related to the consummation of the Formation Transactions, including advisors’ fees, retention costs and stamp duty taxes. Zurich Financial Services reimbursed us for costs and expenses in excess of this amount.

September 11th Coverage

Zurich Financial Services, through its subsidiaries, agreed to arrangements that cap our net exposure for losses and loss expenses arising out of the September 11th terrorist attacks at USD 289.2 million, the amount of net loss and loss expenses we recorded as of September 30, 2001. As part of these arrangements, these subsidiaries of Zurich Financial Services agreed to take responsibility for non-payment by the retrocessionaires of Converium AG and Converium Rückversicherung (Deutschland) AG with regard to losses arising out of the September 11th attacks in excess of the USD 289.2 million cap. Our only retrocessionaire for this business is a unit of Zurich Financial Services. Therefore, we are not exposed to potential non-payments by retrocessionaires for these events in excess of the USD 289.2 million cap, although we are exposed to the risk of non-payment of Zurich Financial Services units and we are exposed to credit risk from these subsidiaries of Zurich Financial Services. Our recorded losses and loss expenses, net of retrocessional recoveries and the cap from ZFS through its subsidiaries, were reduced from USD 289.2 million to USD 231.0 million,

109

following the sale of our North American operations. See — Note 8 to our 2006 consolidated financial statements, and “Item 4. — Information on the Company — B. Business Overview — Retrocessional Reinsurance”.

Acquisition of the Converium AG business

Historically, Converium AG was not a separate legal entity and underwrote substantially all of its business pursuant to reinsurance policies issued by ZIC and ZIB, both subsidiaries of Zurich Financial Services, and was operated as the Zurich Re Zurich business unit of Zurich Financial Services. These subsidiaries were retained by Zurich Financial Services. In June 2001, we incorporated Converium AG, based in Zurich, which is a wholly owned subsidiary of Converium Holding AG. Since October 1, 2001, Converium AG has written its new and renewal business on the balance sheet of the new legal entity.

Certain Converium AG reinsurance business was acquired from ZIC and ZIB via the Quota Share Retrocession Agreement, described in more detail below, and the Asset Purchase and Assumption of Liability Agreement between ZIC and Converium AG, dated September 28, 2001. Under this Agreement, ZIC transferred to Converium AG tangible assets, marketable securities and liabilities relating to the business written by the Zurich operations.

Quota Share Retrocession Agreement

In connection with the Formation Transactions, the transfer of certain historical reinsurance business to Converium AG by ZIC and ZIB was affected by means of the Quota Share Retrocession Agreement effective July 1, 2001. The covered business consists of the business historically managed by Converium, which has an inception or renewal date on or after January 1, 1987 and consists of substantially all of the third party assumed reinsurance business written by ZIC and ZIB, under the “Zurich Re” brand name. The liabilities Converium AG assumed include all net unearned premiums, net losses and loss expenses and experience account balances relating to this business.

The Quota Share Retrocession Agreement provides for the payment of premiums to Converium AG by ZIC as consideration for assuming the covered liabilities. The Quota Share Retrocession Agreement provides that these premiums are on a “funds withheld” basis, whereby the premium is not immediately paid, but is rather retained by ZIC and credited to a funds withheld account, which is referred to as the Funds Withheld Asset.

Because the business subject to the Quota Share Retrocession Agreement consists of business that was historically managed by Converium, this business is already reflected in the financial statements. Any reinsurance business written by ZIC or ZIB that is not part of the historically managed and operated third-party reinsurance business of Converium is not covered by the Quota Share Retrocession Agreement and all related legal rights and obligations of this business have been retained by ZIC and ZIB. Accordingly, this business is excluded from the financial statements. Therefore, execution of the Quota Share Retrocession Agreement has no impact on results of operations as reported.

Converium AG will receive the surplus remaining with respect to the Funds Withheld Asset, if any, after all liabilities have been discharged. Any surplus or any additional cash flows will be recorded in the financial statements in the period when they occur. Additionally, ZFS has the right to prepay to Converium AG the full amount or a portion thereof of the Funds Withheld Asset prior to termination of the agreement.

On December 23, 2005, an Amendment was agreed by the parties to the Quota Share Retrocession Agreements by way of which Section 7.01 — FW Cash Calls — was amended, with immediate effect, to provide, that Converium has the right, by giving 60-days prior written notice to ZFS, to ask for payment in cash on January 1 and July 1 of each calendar year, for the first time on July 1, 2006, of up to 25% of the total funds withheld sub-account balances, as per the most recent quarterly statements, under the respective agreements with ZFS. Furthermore, Converium has the right, at any time upon giving 60-days prior written notice, to ask for the residual balance of the funds withheld account falling below USD 100.0 million, to be paid in cash and in case Converium’s insurers financial strength rating as assigned by Standard & Poor’s is A or higher the latter amount is increased to USD 200.0 million.

Converium AG continues to administer the transferred business on behalf of ZIC and ZIB, which remain liable to the original cedents of the business. Additionally, Converium AG manages third-party retrocessions related to the business transferred. Converium bears the credit risk for uncollectible reinsurance balances excluding those related to the September 11th terrorist attacks. Converium AG has a broad right of offset under the Quota Share Retrocession Agreement so that reinsurance balances owed to ZIC and ZIB may be offset against the Funds Withheld Asset account directly.

110

The Quota Share Retrocession Agreement provides for commutation and termination for special reasons, such as insolvency of a party or loss of its authorization to do business or a change of control of Converium AG or Converium Holding AG. Each of the parties agrees to indemnify the other against liability or expense incurred by reason of its conduct or failure to act in appropriate circumstances. The Quota Share Retrocession Agreement contains other provisions that are customary for an agreement of this nature.

Acquisition of the Converium Rückversicherung (Deutschland) AG business

Converium Rückversicherung (Deutschland) AG was historically known as Agrippina Rückversicherung and subsequently known as ZRK. Historically, Zurich Re Zürich, ZIC and GRI all wrote reinsurance business through policies issued by ZRK. As part of the Formation Transactions, business not managed by us but written on contracts issued by ZRK was novated, commuted or retroceded to affiliates of Zürich Financial Services or third parties. Our financial statements reflect the business that remains the financial responsibility of Converium Rückversicherung (Deutschland) AG and exclude novated and commuted business from all periods presented.

The Converium Rückversicherung (Deutschland) AG reinsurance businesses were acquired through the transfer by Zurich Financial Services to Converium AG of its 98.63% interest in ZRK pursuant to the Agreement for the Sale and Transfer of Shares in Zürich Rückversicherung (Köln) Aktiengesellschaft, dated September 28, 2001. Converium’s interest in Converium Rückversicherung (Deutschland) AG increased to 100% in January 2003.

GRI Retained business

GRI is an internal operating unit of Zurich Financial Services whose principal role is to accumulate risks underwritten by primary and direct providers of insurance in a manner which allows GRI to access the third party reinsurance market. GRI’s internal operations were wholly autonomous from the third party reinsurance business conducted by us. Moreover, Converium never used GRI to access external reinsurance markets.

Prior to the Formation Transactions, the GRI operation was partially conducted through policies issued by CRNA and ZRK. However, the GRI operation was managed exclusively by GRI’s management team. Additionally, Zurich Financial Services did not alter the capital ascribed to support our business as a result of the GRI business formerly written on our balance sheets. As a consequence of the Formation Transactions, all GRI business previously written on our balance sheets has been novated, commuted or retroceded to affiliates of Zurich Financial Services or third parties. Any related rights and obligations of ours have been extinguished. Accordingly, all of this business is excluded from our financial statements.

Other indemnity matters

Pursuant to the Master Agreement, we and Zurich Financial Services have indemnified each other for certain matters, such as liabilities arising out of our respective businesses, and for breaches of our respective representations and warranties and other customary matters.

In particular, we agreed to indemnify Zurich Financial Services and its affiliates for:

•		liabilities assumed by or transferred to us in the separation;

•		liabilities incurred by Zurich Financial Services or its affiliates (other than us) while carrying on business on our behalf pursuant to the terms of agreements entered into in connection with the Formation Transactions before and after the dates of the separation of US and non-US business from Zurich Financial Services;

•		liabilities incurred by us on our own behalf at any time, which are deemed to be or become a liability of Zurich Financial Services or any of its affiliates (other than us); and

•		losses suffered by Zurich Financial Services or any of its affiliates (other than us) that relate to any reasonable action to avoid, resist or defend against liabilities assumed by or indemnified against by us.

Zurich Financial Services correspondingly agreed to indemnify us for:

•

liabilities retained by Zurich Financial Services and its affiliates and not assumed by or transferred to us in the separation;

111

•		liabilities arising out of or relating to the assets not assumed by or transferred to us in the separation;

•		liabilities arising out of specified contracts we have not assumed pursuant to the terms of the Quota Share Retrocession Agreement; and

•		losses suffered by us or any of our affiliates that relate to any reasonable action to avoid, resist or defend against liabilities not relating to our business.

Moreover, we agreed with Zurich Financial Services to allocate amongst ourselves liabilities that may arise under relevant securities laws as a result of any misstatements or omissions contained in the various annual report documentation to be distributed to our shareholders or as a result of the Formation Transactions themselves.

In addition, pursuant to the tax sharing and indemnity agreements described below, we and Zurich Financial Services have agreed to indemnify each other for certain tax liabilities arising out of the Formation Transactions and certain other potential liabilities that arose while we were affiliated with Zurich Financial Services.

Also, we agreed to indemnify Zurich Financial Services and its subsidiaries for losses arising from Zurich Financial Services’ involvement in the MDU strategic partnership to the extent such indemnifiable losses had been caused by the misconduct or negligence of our employees or arising out of our business.

Furthermore, as part of the Underwriting Agreement entered into by Converium and ZFS with the underwriting banks in the IPO, Converium has agreed to indemnify the underwriting banks for certain costs, expenses and/or losses or damages suffered by the underwriting banks in conjunction with the underwriters involvement in the Class Action Law Suits.

Tax sharing agreements

We entered into Tax Sharing and Indemnification Agreements with:

•		ZRCH, in respect of the US Converium entities, which we refer to as the “US Tax Sharing Agreement”; and

•		Zurich Financial Services in respect of the non-US Converium entities, which we refer to as the “Non-US Tax Sharing Agreement”.

The tax allocation agreement in effect involving CRNA and CINA was terminated as to those parties. CRNA and CINA paid the compensation due under the tax allocation agreement through the date of sale of CRNA to CHNA. Under the US Tax Sharing Agreement, payments previously made may be adjusted based on amendments to the tax returns or completion of IRS audits. The US Tax Sharing Agreement provides we will generally be liable for taxes imposed on our US entities in respect of periods prior to and after the transfer. However, ZRCH will be liable to us for specified taxes, which will include any taxes arising out of the transfer of the US entities to us, any taxes imposed in respect of the stop-loss reinsurance policy from ZIC from 1997 to 2001 and certain other matters.

The Non-US Tax Sharing Agreement provides in general that we will be liable for all taxes arising from the business previously conducted by ZIC and Zurich Rückversicherung (Deutschland) AG, whether arising prior to or subsequent to the transfer to Converium. We are also liable for branch taxes arising from the Converium branches located in Malaysia, Singapore and Australia as well as representative offices in Buenos Aires, London, Sao Paolo, Kuala Lumpur and Tokyo. As described above, under the Master Agreement we will be liable for all taxes related to the consummation of the Formation Transactions together with all other costs and expenses of our Initial Public Offering, up to an aggregate of USD 50 million. In addition, all taxes relating to the Formation Transactions but incurred after the Formation Transactions will be borne by Converium. See “— The Master Agreement”.

The tax sharing agreements also set forth the responsibilities for filing tax returns affecting the Converium entities, and the conduct of audits and similar proceedings. The obligations of ZRCH under the US Tax Sharing Agreement are guaranteed by ZIC.

Swiss tax consequences to Converium of the Formation Transactions

112

Under the terms of the Swiss tax rulings obtained by Zurich Financial Services and granted by the Swiss Federal and Zurich Cantonal Tax Administrations, the offering of Converium shares to the public in our initial public offering triggered retroactively Swiss stamp duty at the rate of 1% of the fair market value of Converium at the level of Converium Holding AG.

As part of the Master Agreement, Zurich Financial Services has agreed to reimburse us for certain costs and expenses related to the Formation Transactions, including the stamp duty taxes described above. See “— The Master Agreement”.

Continuing relationships with Zurich Financial Services

In addition to the agreements described above, we have certain continuing relationships with Zurich Financial Services, including those described below.

Other agreements and arrangements

As described in more detail above, the separation of our business from that of Zurich Financial Services, in part pursuant to reinsurance agreements, including the Quota Share Retrocession Agreement and the Master Novation and Indemnity Agreement, has entailed us and Zurich Financial Services and its affiliates having continuing obligations to reinsure each other and to provide services in connection with the administration of the run-off of the business we transferred to each other.

Lease arrangements

Converium AG leases office space from Zurich Financial Services. The lease term is fixed until 2011, with two renewal options for three-year terms each. The lease payments are fixed with annual rent escalations based on a cost of living index.

Converium Rückversicherung (Deutschland) AG leases office space from Oppenheim Immobilien Kapitalanlagegesellschaft mbH (Zürich Lebensversicherung Aktiengesellschaft) Deutschland) before the sale of the building. The lease term is for a period of ten years ending in 2008, with an option to renew for up to two additional ten-year terms. Lease payments have bi-annual rent escalations based on changes in local real estate price indices.

SCOR Transaction Agreement

On April 5, 2007, SCOR formally commenced a then- unsolicited tender offer for Converium. On May 9, 2007, Converium and SCOR entered into the SCOR Transaction Agreement pursuant to which SCOR agreed to increase the consideration payable in the SCOR Tender Offer to 0.5 new SCOR shares and CHF 5.50 in cash in exchange for each Converium registered share tendered and Converium agreed that its Board of Directors would recommend the improved SCOR Tender Offer to Converium shareholders. The Company has agreed that during the pendency of the SCOR Tender Offer it will continue to operate its business in the ordinary course consistent with past practice and abstain from taking any actions outside the ordinary course of business consistent with past practice. The Company has also agreed to refrain from continuing, or entering into, discussions with third parties which could result in a tender offer for Converium’s registered shares or otherwise result in a merger, sale of assets, restructuring or recapitalization of the Company. Pursuant to the SCOR Transaction Agreement, the Company must promptly give notice to SCOR the Company receives a superior offer, which is generally defined to include any public offer to all of the Company’s shareholders on terms and conditions that the Board of Directors determines in good faith, after consideration of its fiduciary duties, to be superior for the Company’s shareholders when compared as a whole to the terms and conditions of the SCOR Tender Offer, provided that (i) the consideration offered is not less than that offered by SCOR on a fully diluted basis and (ii) the conditions of a superior offer are no more restrictive than the conditions of the SCOR Tender Offer (a “Superior Offer”). During the three day period following the delivery of notice of a Superior Offer to SCOR, the Company and SCOR have agreed to renegotiate in good faith the terms of the SCOR Tender Offer. If the Company and SCOR are unable to renegotiate the terms of the SCOR Tender Offer, the Company’s Board of Directors may withdraw their recommendation of the SCOR Tender Offer and the Company may terminate the SCOR Transaction Agreement.

Pursuant to the SCOR Transaction Agreement, the Company has agreed that each of its current members of the Board of Directors will resign if the SCOR Tender Offer is successful. The Company has also agreed that following the settlement of the SCOR Tender Offer, the employment contracts of Inga Beale, our Chief Executive Officer, and of Paolo De Martin, our Chief Financial Officer, will be terminated with effect as of December 31, 2007. Pursuant to the termination agreement to be entered into with Ms. Beale following the settlement of the SCOR Tender Offer, Ms. Beale will be entitled to receive a lump sum payment in the amount of CHF 4.2 million in full settlement and discharge of any rights of any nature, whether known or unknown, actual or contingent, that Ms. Beale may have against the Company on December 31, 2007. Pursuant to the termination agreement to be entered into with Mr. De Martin following the settlement of the SCOR Tender Offer, Mr. De Martin will be entitled to receive a lump sum payment in the amount of CHF 2.5 million in full settlement and discharge of any rights of any nature, whether known or unknown, actual or contingent, that Mr. De Martin may have against the Company on December 31, 2007.

Following the settlement of the SCOR Tender Offer, SCOR has agreed to maintain Converium’s strong presence in Zurich, Switzerland.

D. EXCHANGE CONTROLS AND OTHER LIMITATIONS

Other than in connection with government sanctions imposed on Yugoslavia, Myanmar, Zimbabwe, Iraq, Ivory Coast, Liberia, Sierra Leone, Uzbekistan, Belarus, Sudan, North Korea, Congo, Lebanon, Iran and persons and organizations with connections to Osama bin Laden, the “al Qaeda” group or the Taliban, there are currently no laws, decrees or regulations in Switzerland that restrict the export or import of capital, including, but not limited to, Swiss foreign exchange controls on payment of dividends, interest or liquidation proceeds, if any, to non-Swiss resident holders of shares. In addition, there are no limitations imposed by Swiss law or the Company’s Articles of Incorporation on the rights of non-Swiss residents or non-Swiss citizens to hold or vote the shares of the Company.

There are currently no laws, decrees or regulations in Luxembourg that restrict the export or import of capital, including, but not limited to, Luxembourg foreign exchange controls on the payment of principal, interest or liquidation proceeds, if any, to non-resident holders of notes.

E. TAXATION

The following is a summary of the principal US Federal income tax and Swiss tax consequences to a holder of shares or ADSs. This discussion does not purport to address all tax consequences of the acquisition, ownership and disposition of shares or ADSs and does not take into account the specific circumstances of any particular holders (such as tax-exempt entities, certain insurance companies, broker-dealers, traders in securities that elect to mark to market, holders liable for alternative minimum tax, holders that actually or constructively own 10% or more of the voting shares of Converium, holders that hold shares or ADSs as part of a straddle or a hedging or conversion transaction or holders whose functional currency is not the US dollar, etc.), some of which may be subject to special rules. This summary is based on the tax laws of Switzerland and the United States (including the Internal Revenue Code of 1986, as amended (the “Code”), its legislative history, existing and proposed regulations thereunder, published rulings and court decisions as in effect on the date hereof), as well as the Convention Between the United States of America and the Swiss Confederation, which we call the US/Switzerland Treaty, all of which are subject to change (or change in interpretation), possibly with retroactive effect. We have not, and will not, request a ruling from the US Internal Revenue Service concerning the tax consequences of any aspect of the transactions described herein. This discussion does neither generally address any aspects of Swiss taxation other

113

than income and capital taxation and Swiss stamp duties nor of US taxation other than federal income taxation. Holders are urged to consult their tax advisors regarding the Swiss and other tax consequences of owning and disposing of shares or ADSs as well as the US federal, state and local and other tax consequences of owning and disposing of shares or ADSs.

Swiss taxation

Generally, holders of ADSs will be treated as owners of the registered shares underlying the ADSs for Swiss tax purposes. Accordingly, except as noted, the Swiss tax consequences discussed below apply equally to holders of the registered shares and ADSs.

This discussion does not, as already mentioned above, generally address any aspects of Swiss taxation other than income and capital taxation and Swiss stamp duties. Holders are urged to consult their tax advisors regarding the Swiss and other tax consequences of owning and disposing of shares or ADSs.

Withholding tax on dividends and distributions

Dividends paid and similar in-kind distributions (including dividends of liquidation proceeds and share dividends) made by Converium to a holder of shares or ADSs are subject to a federal withholding tax at a rate of 35%. The withholding tax must be withheld by Converium from the gross distribution, and paid over to the Swiss Federal Tax Administration. The withholding tax is refundable in full to a Swiss resident who receives a distribution if such resident is the beneficial owner of the payment and duly reports the gross distribution received on his personal tax return.

Obtaining a refund of Swiss withholding tax for US residents

Article 10 of the US/Switzerland Treaty provides for a reduced 15% withholding tax rate for US individual and corporate shareholders who are entitled to claim treaty benefits, which may be further reduced to 5% in the case of a corporate shareholder owning at least 10% of the voting rights. Relief under the US/Switzerland Treaty is granted by way of a refund. Under the ADS program in effect through The Bank of New York, a US holder of ADSs that qualifies for US/Switzerland Treaty benefits will not be required to undertake any action with respect to the partial or full refund of the Swiss withholding tax. On the payment date of the dividend, Converium will pay 65% of the gross dividend to The Bank of New York on behalf of the ADS holders. The Bank of New York will file a Form 82 accompanied by a shareholder list and a DTC participant list for each program. Based on this refund application, the refundable withholding tax will be refunded by the Swiss Federal Tax Administration to The Bank of New York on behalf of the eligible US holders of ADSs. The Bank of New York will pay 85% or 95% of the dividend to the eligible US holders of ADSs, depending on the applicable US/Switzerland Treaty rate. Such holders should receive the ADS dividend within approximately one month of the payment of the dividend by Converium. Relief under the US/Switzerland Treaty is granted for holders of shares by way of a refund of the withholding tax. A US holder of shares may obtain the applicable refund of Swiss withholding tax by filing a Swiss Federal Tax Administration Form 82 with the Swiss Federal Tax Administration.

Income tax on dividends

A Swiss resident or a foreign resident subject to Swiss taxation who receives a dividend or similar distribution (including liquidation proceeds in excess of the nominal value of the shares) from us is required to include such amounts in his personal income tax return. In some cantons such person may be entitled to a privileged tax treatment of such dividend income for cantonal and municipal tax purposes. However, such beneficial treatment generally requires a substantial shareholding in Converium. A Swiss shareholder which itself is a company or a cooperative may, under certain circumstances, benefit from an exemption of the dividend from income taxation (participation exemption/Beteiligungsabzug).

For purposes of the above paragraph and the discussion under “Capital Gains Tax upon Disposal of Shares”, a foreign resident subject to Swiss taxation refers to a non-Swiss resident person that maintains in Switzerland a permanent establishment or fixed place of business to which the shares are attributable.

Capital gains tax upon disposal of shares

A Swiss resident who holds shares as part of such resident’s private, non-business assets will not be subject to any Swiss federal, cantonal or municipal income taxation on gains realized upon the sale or other disposal of shares. However, under certain conditions, shares can be deemed to be part of the business assets of an individual, i.e. an individual may be treated as a professional trader in securities, with the consequence of taxation of any capital gains as business income. Furthermore, private gains realized upon a

114

repurchase of shares by us may be re-characterized as taxable dividend income if some conditions are met. In the case of such re-characterization of capital gains into dividend income, income tax will be levied on the difference between the repurchase price and the underlying nominal value of the shares. Capital gains realized on shares held as part of the business assets of a Swiss resident or a foreign resident subject to Swiss taxation are included in the taxable income of such persons.

Persons who are not resident in Switzerland for tax purposes are not subject to any Swiss taxes with respect to gains realized upon a sale of shares or ADSs, unless the shares or ADSs are attributable to a permanent establishment or fixed place of business maintained by such non-resident person in Switzerland. However, under some conditions, dividend withholding tax will become due if shares are repurchased by Converium.

A Swiss resident or a foreign resident subject to Swiss taxation which is a shareholder and which itself is a company or a cooperative may, under certain circumstances, be eligible for relief from taxation with respect to capital gains (participation exemption/Beteiligungsabzug). However, the participation exemption on capital gains applies only in the case of a shareholding quota sold of at least 20% held over an uninterrupted period of at least one year.

Stamp Duties upon transfer of shares

The sale or purchase of shares or ADSs, whether by Swiss resident or non-resident holders, may be subject to a Swiss securities transfer stamp duty, calculated on the sale proceeds, if it occurs through or with a Swiss bank or other Swiss securities dealer as defined in the Swiss Federal Stamp Tax Act.

United States federal income taxation

This discussion applies only to beneficial owners of shares or ADSs that hold the shares or ADSs as capital assets and are US holders. For purposes of this discussion, a “US holder” for US federal income tax purposes is either (1) a citizen or resident of the United States, (2) a corporation, or other entity treated as a corporation, organized under the laws of the United States or any state thereof or the District of Columbia thereof, (3) an estate the income of which is subject to US federal income tax without regard to its source, or (4) a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more US persons have the authority to control all substantial decisions of the trust.

This discussion does not, as already mentioned above, address any aspects of US taxation other than US federal income taxation and it does not purport to be a comprehensive discussion of all the US federal income tax considerations that may be relevant to a particular person’s individual circumstances. Holders are urged to consult their tax advisors regarding the US federal, state and local and other tax consequences of owning and disposing of shares or ADSs.

US holders of ADSs will be treated as owners of the shares underlying the ADSs for US federal income tax purposes. Accordingly, except as noted, the US federal income tax consequences discussed below apply equally to US holders of ADSs and shares. This discussion is based in part upon representations of The Bank of New York and assumes that each obligation provided for in, or otherwise contemplated by, the deposit agreement and any related agreement will be performed in accordance with its respective terms.

Taxation of dividends

Subject to the passive foreign investment company (“PFIC”) rules described below, US holders will include in gross income the gross amount of any distribution, other than certain pro rata distributions of common shares, paid (before reduction for Swiss withholding taxes) by Converium out of its current or accumulated earnings and profits (as determined for US federal income tax purposes) as foreign source ordinary income when the dividend is actually or constructively received by the US holder. The dividend will not be eligible for the dividends-received deduction. Dividends paid to a non-corporate US holder before January 1, 2011 will be taxable to the holder at a maximum tax rate of 15% provided that the shares or ADSs are held for more than 60 days during the 121 day period beginning 60 days before the ex-dividend date and the holder meets other holding period requirements. The amount of the dividend paid in Swiss francs will be the US dollar value of the Swiss francs received, including the amount of any Swiss tax withheld, determined at the spot Swiss franc/US dollar rate on the date such dividend is received, which for holders of ADSs would be the date such dividend is received by The Bank of New York, regardless of whether the payment is in fact converted into US dollars. Generally, any gain or loss resulting from currency exchange fluctuations will be treated as ordinary income or loss. Such gain or loss will generally be income from sources within the United States for foreign tax credit limitation purposes. Distributions in excess of current and accumulated earnings and profits, as determined for US federal income tax purposes, will be treated as a return of capital

115

to the extent of the US holder’s basis in the shares or ADSs and thereafter as capital gain. The amount of any distribution of property other than cash will be the property’s fair market value on the date of the distribution.

Subject to certain limitations, the Swiss tax withheld in accordance with the US/Switzerland Treaty and paid over to Switzerland will be creditable against the US holder’s US federal income tax liability. One such limitation is that a foreign tax credit is only allowed for withholding tax on a dividend if the shareholder has held the shares with respect to which the dividend is paid for more than 15 days during the 31 day period beginning on the date which is 15 days before the date on which the shares become ex-dividend with respect to the dividend. To the extent a refund of the tax withheld is available to a US holder under the US/Switzerland Treaty, the amount of tax withheld that is refundable will not be eligible for credit against the US holder’s US federal income tax liability. See “— Swiss Taxation — Obtaining a Refund of Swiss Withholding Tax for US Residents” above for the procedures for obtaining a refund of tax.

The ability of a US holder to utilize foreign taxes as a credit to offset US taxes is affected by complex limitations and conditions. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, dividends paid by Converium will generally constitute “passive income”.

A US holder may elect to claim all foreign taxes paid as an itemized deduction in lieu of claiming a foreign tax credit. A deduction does not reduce US tax on a dollar-for-dollar basis like a tax credit could, but the availability of the deduction is not affected by the conditions and limitations applicable to foreign tax credits. US holders should consult their tax advisors to determine whether and to what extent a foreign tax credit would be available to them.

The US Treasury Department has expressed concern that parties to whom ADSs are pre-released may be taking actions that are inconsistent with the claiming by US holders of ADSs of foreign tax credits for US federal income tax purposes. Such actions would also be inconsistent with the claiming of the reduced rate of tax applicable to dividends received by certain non-corporate US holders, described above. Accordingly, the discussion of the creditability of foreign taxes and the availability of the reduced rate for dividends received by certain non-corporate US holders could be affected by future actions that may be taken by the US Treasury Department.

Sale or exchange

Subject to the PFIC rules described below, gain or loss recognized by a US holder on the sale, exchange or other disposition of shares or ADSs will be subject to US federal income taxation generally as capital gain or loss in an amount equal to the difference between the US holder’s adjusted tax basis in the shares or ADSs and the amount realized on the disposition. Capital gain or loss will be long-term capital gain or loss where the shares or ADSs have been held for more than one year. Any gain or loss recognized will generally be treated as US source gain or loss. US holders are urged to consult their own tax advisors about the treatment of capital gains, which may be taxed at lower rates than ordinary income for non-corporate taxpayers, and capital losses, the deductibility of which may be limited.

The surrender of ADSs in exchange for shares, or vice versa, will not result in the realization of gain or loss for US federal income tax purposes.

PFIC rules

Converium believes that it was not a PFIC for US federal income tax purposes for 2006and it does not expect to be considered a PFIC in the foreseeable future. However, since PFIC status depends upon the composition of a company’s income and assets and the market value of its assets (including, among others, less than 25 percent owned equity investments), there can be no assurance that Converium will not be considered a PFIC for any taxable year. If Converium were treated as a PFIC for any taxable year during which a US holder held a share or ADS, certain adverse consequences could apply to the US holder.

If Converium were treated as a PFIC for any taxable year, gain recognized by such US holder on a sale or other disposition of a share or ADS would be allocated ratably over the US holder’s holding period for the share or ADS. The amounts allocated to the taxable year of the sale or other exchange and to any year before Converium became a PFIC would be taxed as ordinary income in the year of the disposition. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect (for individuals or corporations, as appropriate) for the year to which it is allocated and an interest charge would be imposed on the amount allocated to such taxable year. This tax and interest is treated as a direct increase to the US holder’s tax liability for the current year. Further, any distribution in respect of ADSs or shares in excess of 125 percent of the average of the annual distributions on ADSs or shares received by the US holder during the preceding three years or the US holder’s holding period, whichever if shorter, would be subject

116

to taxation as described above. Certain elections (including the mark to market election and the qualified electing fund election) may be available to US persons that may mitigate the adverse consequences resulting from PFIC status.

In addition, if Converium were to be treated as a PFIC in a taxable year in which Converium pays a dividend or the prior taxable year, the 15% dividend rate discussed above with respect to dividends paid to non-corporate US holders would not apply.

Backup withholding

A US holder may, under certain circumstances, be subject to “backup withholding” with respect to dividends paid on the shares or ADSs or the proceeds of sale, exchange, or other disposition of shares or ADSs unless such holder (1) is a corporation or comes within certain other exempt categories, and, when required, demonstrates this fact or (2) provides a correct taxpayer identification number, certifies that it is not subject to backup withholding and otherwise complies with applicable requirements of the backup withholding rules. Any amount withheld under these rules will be creditable against the US holder’s federal income tax liability, provided appropriate information is furnished to the IRS. A US holder who does not provide a correct taxpayer identification number may be subject to penalties imposed by the IRS.

ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

As a provider of reinsurance solutions, effective risk management is fundamental to our ability to protect both the interests of our clients and shareholders. We have accordingly established risk and investment management processes and procedures to actively manage our exposure to qualitative and quantitative market risks. Our risk and investment management procedures focus on ensuring that all of our operating units consistently follow suitable, structured and controlled processes and procedures, with specific guidelines and limits tailored to the characteristics of each business.

We consider our market risk to consist primarily of our exposure to adverse market value changes in our assets, across both short-and long-term periods. Our market risk includes multiple sources of market price fluctuations, including interest rate risks, credit risks, prepayment risks, liquidity risks, sector risks and other risks. Short-term market risks relate primarily to our exposure to adverse market value changes in our assets and the potential inability to realize asset values on a timely basis.

We principally manage our long-term market risks through a procedure we refer to as asset/liability management, or ALM, through

117

which we seek to understand and manage the dynamic interactions between our assets and liabilities. We utilize and continually develop firm-wide ALM processes and models to manage our aggregate financial risks and the correlation between financial risks and underwriting risks. The primary goal of our ALM procedures is to match, in terms of timing and currency, anticipated claims payments to our cedents with investment income and repayments generated by our invested assets and to improve our understanding of the correlation between financial risks and underwriting risks. Because fixed income securities generally provide more stable investment income than equity securities, the preponderance of our investments are in fixed income instruments. Although our ALM techniques are based on theoretical and empirical models and can lead to incorrect assumptions, we believe that the careful use of these ALM techniques leads to a better understanding of the risks inherent in our assets and liabilities and is therefore an important element of our risk and investment management process. Our principal ALM techniques include cash flow analysis, scenario testing and stochastic modeling. (See the ALM graph in the Risk Management section).

To help manage our aggregate exposure to concentration and credit risks, we analyze the concentration of our risk by entity, risk category (asset, underwriting, retrocession), industry and credit rating. These concentrations and credit risks are reviewed every six months by our ALM Committee as a part of the review and approval of the ALM report.

Sensitivity analyses for invested assets

Approximately 88.8% of our investment securities are classified for accounting purposes as available-for-sale. These securities are carried at their fair market value as of the balance sheet date with movements in fair value recorded in shareholders’ equity. In contrast to these assets, certain liability reserves, particularly non-life reinsurance reserves, are not shown at fair market values as of the balance sheet date. Therefore, US GAAP accounting practices typically result in more volatile assets than liabilities. This, in turn, may lead us to report more volatile shareholders’ equity on our balance sheet than we believe may economically be the case.

The following risk analyses on interest rate, foreign exchange and equity market risks do not take into account that there are strategies in place to minimize the exposures to market fluctuations. These strategies include, among others, changes in asset allocation and the sale of investments and the management of the portfolio duration. As the risk analyses focus on the identification of risk exposures that impact the market value of assets alone and assume that the change in the value of assets is temporary while the liability reserves would not change, it is important for the reader to recognize that the risks discussed herein are significantly mitigated to the extent that the Company’s investment strategy allows market forces to influence the economic valuation of both assets and liabilities in generally the same way.

	•		Interest rate risk — We have based our computations of interest rate sensitivity on numerous assumptions. Therefore they should not be relied on as indicative of future results.

			Our investments are subject to interest rate risks. Fluctuations in interest rates have a direct impact on the market valuation of our fixed income portfolio, such that market values of fixed income securities fall as interest rates rise and vice versa. Our interest rate risk is concentrated in the United States, United Kingdom and Europe and is highly sensitive to many factors, including governmental monetary policies and domestic and international economic and political conditions. The estimated potential exposure of our total fixed income securities portfolio to a one percentage point increase of the corresponding government bond yield curves would be an after-tax reduction in net assets of USD 86.8 million, which represents approximately 4.7% of our total shareholders’ equity as of December 31, 2006. This reduction would be offset by higher investment income earned on newly invested funds.

			The Company manages interest rate risk by constructing bond portfolios in which the economic impact of a general interest rate shift is comparable to the impact on the related liabilities. To protect our balance sheet from a possible rise of the yield curves, we stabilized our modified duration of our bond portfolio, excluding held-to-maturity securities, to 3.3. Additionally, our portfolio of held-to-maturity government bonds reduced to USD 718.3 million (18.7% of our fixed maturities portfolio, excluding the Funds Withheld Asset) attributable to the sale of our discontinued operations and maturing fixed maturities securities. The duration of the held-to-maturity portfolio is 2.8. The Company believes that this matching process mitigates the overall interest rate risk on an economic basis.

			As of December 31, 2006, all of our debt outstanding was at fixed interest rates. Thus, an increase in interest rates would currently have no effect on our annual interest expense or reported shareholders’ equity, as we account for debt at amortized cost, not fair value.

	•		Equity market risk — We hold approximately 11.5% (including our participation in PSP Swiss Property AG and Real Estate Equity Securities) of our invested assets in equity securities, which are subject to equity market risk. Our equity market risk is

118

			predominantly in developed markets and concentrated in the United States, United Kingdom and Europe and is highly sensitive to general economic and stock market conditions. The equity investment portfolio is invested in broad market indices in order to achieve desired diversification and market performance. The estimated potential exposure of our consolidated net assets to a 10% decline in all stock markets as of December 31, 2006 would be an after-tax reduction in net assets of USD 62.4 million, which represents approximately 3.4% of our total shareholders’ equity as of December 31, 2006.

			Our strategic asset allocation combines a large percentage of investments in high-quality bonds with investments in equity securities. This allocation seeks to generate strong positive returns with acceptable risks over the long term, while protecting against excessive risks in periods of severe market distress.

			During a severe stock market correction associated with a weak economy, recession or depression, losses in the fair market value of equity securities tend to be partially offset by gains on high-quality bonds arising from falling interest rates. We seek to match our investments with our underlying liabilities in the countries and territories in which we operate. Consequently, we strive to keep our equity portfolio diversified so as to provide a broad exposure across major sectors of individual stock markets. We restrict our maximum investment in any one equity security or equity sector by reference to local benchmarks and insurance regulations.

	•		Foreign exchange risk — Our general practice is to invest in assets that match the currency in which we expect related liabilities to be paid. We tend thus to invest our assets with the same currency allocation as our technical liabilities. This results in the same currency split for the assets backing our shareholders’ equity. This practice supports sound currency asset/liability management, but if not properly matched, there is a translation risk of currency rate changes against the US dollar that may adversely affect our reported shareholders’ equity when expressed in US dollars.

			Shareholders’ equity held in local insurance units is primarily kept in local currencies to the extent that shareholders’ equity is required to satisfy regulatory and self-imposed capital requirements. This facilitates our efforts to ensure that capital held in local insurance units will be able to support the local insurance business irrespective of currency movements. In line with our functional currency concept, the differences resulting from the currency rate changes are recorded in shareholders’ equity as cumulative currency translation adjustments.

Certain shortcomings are inherent in the method of analysis presented in the computation of the fair value of fixed rate instruments. Actual values may differ from those projections presented should market conditions vary from assumptions used in the calculation of the fair value of individual securities, including non-parallel shifts in the term structure of interest rates and changing individual issuer credit spreads.

The table below shows the approximate effect on shareholders’ equity of instantaneous adverse movements in currency exchange rates of 10% on our major currency exposures at December 31, 2006 against the US dollar.


	Adverse exchange rate movement against			Approximate decline
	the US dollar			in shareholders'equity
Euro		10	%	USD155.3 million
Swiss franc		10	%	USD15.0 million
UK pound		10	%	USD188.0 million

As of December 31, 2006 and 2005, we had unrealized cumulative translation gains of USD 191.9 million and USD 96.9 million, respectively.

Our reported premiums, losses and expenses are also affected by exchange rate fluctuations. Business written in currencies other than the US dollar is translated at average exchange rates for the period and therefore exchange rate movements from period to period can have a significant effect on our US dollar reported premiums, losses and expenses.

ITEM 15. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The Company’s Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of the end of the period covered by this annual report on Form 20-F. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that, as of the evaluation date, the Company’s disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms and is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control over Financial Reporting

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)). The Company’s internal control over financial reporting is a process designed by, or under the supervision of, the Company’s Chief Executive Officer and Chief Financial Officer, or persons performing similar functions, and effected by the Company’s board of directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of its financial statements for external purposes in accordance with generally accepted accounting principles.

Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the Company’s assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements.

120

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

The Company’s management has assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006 based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management has determined that the Company’s internal control over financial reporting was effective as of December 31, 2006.

The Company’s independent registered public accounting firm, PricewaterhouseCoopers Ltd., that has audited the financial statements included in this annual report on Form 20-F has issued a report on management’s assessment of the Company’s internal control over financial reporting as of December 31, 2006.

Report of the Registered Public Accounting Firm

The report of PricewaterhouseCoopers Ltd. on management’s assessment of the Company’s internal control over financial reporting as of December 31, 2006 is included on page F-2 of this annual report on Form 20-F.

Formerly Reported Material Weaknesses and Changes in Internal Control over Financial Reporting

As a foreign private issuer we are subject to Section 404 of the Sarbanes-Oxley Act (“SOX 404”). Therefore, in 2006 the processes and controls implemented in conjunction with our Sarbanes-Oxley project were tested by management and external auditors. For purposes of SOX 404, a “material weakness” is a significant deficiency, or combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected.

The first material weakness identified as of December 31, 2004 was the need to train or recruit suitably qualified individuals to fill the knowledge and experience gaps about US-GAAP caused by the departure of various key finance employees. The second material weakness identified was the failure in the operation of key internal controls over the initiation of reinsurance and financial accounting data. The third material weakness identified was the lack of controls to ensure that the underwriting and risk transfer analyses reflect all relevant elements of contractual relationships entered into by Converium. The fourth material weakness identified relates to internal controls over the determination, valuation, completeness and reporting of certain components of the income tax payables and deferred income tax balances (assets and liabilities). The material weaknesses two, three and four were identified in 2005.

Converium had remediated the first material weakness as of December 31, 2005. The second, third and fourth material weaknesses identified in previous years were also remediated as of December 31, 2006.

There were changes to enhance our internal controls over financial reporting during the period covered by this Form 20-F that have materially improved, or are reasonably likely to materially affect, our internal controls over financial reporting. Such changes included the following:

- Implementation of an accounting policy manual and additional US-GAAP training sessions,

- Improvement of controls over data quality by optimization of related applications, processes and organization,

- Revision of underwriting non-life guidelines and constitution of a FAS 113 expert team,

- Recruitment of tax specialists and revision of tax controls and processes,

As a result of the remedial actions taken, and based on management’s testing of Converium's Internal Controls over Financial Reporting, the Company’s management concludes that there are no material weaknesses.

Whistleblower Procedure

An anonymous “whistleblower” procedure has been established, allowing confidential reporting and evaluation of complaints regarding questionable accounting methods or fraudulent practices, as well as other risk-related operational hazards such as inadequate controls or organizational shortcomings. Through Group Internal Audit, such anonymous reporting goes directly to the Audit Committee of the Board of Directors.

Duration of the Mandate and Terms of Office of the Independent Auditors

PricewaterhouseCoopers Ltd, our principal independent group auditor, began serving as our auditor upon the formation of Converium in 2001. The audit partners responsible for our audit, Andrew Hill and Martin Frei, began serving in their roles in 2002 and 2003, respectively. As part of the normal audit partner rotation Lilla Runco and Wanda Eriksen will take over as responsible audit partners commencing with the 2007 audit engagement.

Policy on Pre-Approval and Non-Audit Services of Independent Auditors

Our Audit Committee comprises the Chairman of the Board of Directors and the Chairmen of the Finance, Nomination and Remuneration Committees and the independent financial expert of the Board. Only independent and financially literate Directors are eligible to serve on the Audit Committee. In order to qualify as independent, a member may not accept any consulting, advisory or compensatory fee from us. In addition, an Audit Committee member may not be a person affiliated with the Company or any of its subsidiaries. The Audit Committee approves and supervises the implementation of Converium’s Audit Charter, including the review of internal control systems and Converium’s risk management and auditing processes; reviews and assesses significant accounting and reporting issues; oversees external and internal auditors and the external and internal audit process; assesses the accuracy of the annual financial statements and determines that appropriate accounting principles have been applied; and liaises with Converium’s Risk Management functions to identify Converium’s areas of greatest risk and to assess management’s role in mitigating the risks. Standing invitees are the CEO, the Head of Internal Audit and the external auditor. In 2006, the Audit Committee met nine times physically and held one meeting by way of conference call.

The Audit Committee has the responsibility to pre-approve all audit fees, fees for audit related services, tax advisory fees provided by Converium’s external independent group auditors and all non-audit related fees. Converium implemented protocols and guidelines to ensure that only pre-approved services are provided by Converium’s external independent group auditors.

Converium Holding AG and Subsidiaries

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Converium Holding AG, Zurich

We have completed an integrated audit of Converium Holding AG and its subsidiaries (“the Converium Group’s”) 2006 consolidated financial statements and of its internal control over financial reporting as of December 31, 2006 and audits of its 2005 and 2004 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board of the United States of America. Our opinions, based on our audits, are presented below.

Consolidated financial statements

As auditors of the Converium Group, we have audited the consolidated financial statements (comprising consolidated balance sheet, income statement, statement of cash flows, statement of changes in equity and notes), set out on pages F- 3 to F-57 of the 2006 Annual Report on Form 20-F, of Converium Holding AG as of December 31, 2006 and 2005 and for each of the three years in the period ended December 31, 2006.

These consolidated financial statements are the responsibility of the Board of Directors. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

Our audits were conducted in accordance with Swiss Auditing Standards and with the Standards of the Public Company Accounting Oversight Board of the United States of America, which require that an audit be planned and performed to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used, and significant estimates made and evaluating the overall consolidated financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements, after the restatement described in note 1(a), present fairly, in all material respects, the financial position of Converium Holding AG and its subsidiaries at December 31, 2006 and 2005 and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2006, in accordance with accounting principles generally accepted in the United States of America.

As discussed in Note 13, the Converium Group changed its accounting for pensions in accordance with SFAS 158.

Internal control over financial reporting

We have also audited Management’s assessment, included in “Management’s Annual Report on Internal Control Over Financial Reporting”, appearing in Item 15 of the 2006 Annual Report on Form 20-F, that the Converium Group maintained effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control- Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Converium Holding AG’s Board of Directors and Management of the Converium Group are responsible for maintaining effective internal control over financial reporting and Management is responsible for the assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on Management’s assessment and on the effectiveness of the Converium Group’s internal control over financial reporting based on our audit.

We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board of the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating Management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of Management and Directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

In our opinion, Management’s assessment, included in “Management’s Annual Report on Internal Control Over Financial Reporting”, appearing in Item 15 of the 2006 Annual Report on Form 20-F, that the Converium Group maintained effective internal control over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on criteria established in Internal Control - Integrated Framework issued by the COSO.

Also, in our opinion, the Converium Group maintained, in all material respects, effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control - Integrated Framework issued by the COSO.

Converium Holding AG and Subsidiaries

Notes to the consolidated financial statements

1. Basis of preparation and significant accounting policies

(a) Basis of preparation

Converium Holding AG and subsidiaries (“Converium” or the “Company”) is an international reinsurer whose business operations are recognized for innovation, professionalism and service. As a multi-line reinsurer, we pursue a strategy of profitable organic growth with a geographic emphasis on Europe, Asia-Pacific, Central and South America and the Middle East and a distinct focus on global specialty lines.

Converium’s financial statements have been prepared on the basis of accounting principles generally accepted in the United States (“US GAAP”) and comply with Swiss law and are stated in US dollars (“USD”).

The consolidated financial statements include all companies which Converium, directly or indirectly controls (more than 50% of voting rights). Investments in associated companies and joint ventures are accounted for by using the equity method with Converium recording its share of the associated company’s net income and shareholders’ equity.

Discontinued operations

On December 13, 2006, the Company sold all of its outstanding shares of capital stock in Converium Holdings (North America) Inc, to National Indemnity Company, a Berkshire Hathaway company, and accordingly, the operating results related to the North American operations including prior period amounts have been reclassified to discontinued operations. Prior year consolidated balance sheets and consolidated statements of cash flows have not been adjusted.

Restatement

An adjustment has been made to restate January 1, 2004 shareholders’ equity components related to a specific reinsurance transaction, such that retained earnings increased and additional paid-in capital decreased by USD 58.6 million as at December 31, 2002. There is no net effect on shareholders’ equity.

Segment presentation

Converium currently provides its services through three segments, Standard Property & Casualty Reinsurance, Specialty Lines and the Life & Health segment. Our North American operations were previously reported as the principal component of a separate segment, the Run-Off segment. In addition to the three segments’ financial results, the Corporate Center carries certain administration expenses, such as costs of the Board of Directors, the Global Executive Committee and other corporate functions as well as expenses not allocated to the operating segments. Management also aggregates results for Standard Property & Casualty Reinsurance and Specialty Lines into non-life business, as management considers this aggregation meaningful in understanding the performance of Converium.

Certain reclassifications have been made to prior year financial information to conform to the current year presentation.

(b) Use of estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Therefore, actual results could differ from those estimates.

The most significant estimates include those used in determining reserves for non-life loss and loss adjustment expenses, premium accruals and deferred policy acquisition costs, reinsurance recoverables, impairments, income taxes and commitments and contingencies.

(c) Foreign currency

Converium’s main functional currencies include the Euro, the UK pound, the Swiss franc, the US dollar and the Japanese yen. Assets and liabilities of all of Converium’s branches and subsidiaries expressed in currencies other than US dollars are translated at the end of period exchange rates, whereas statements of income and cash flows are translated at average exchange rates for the period. Translation differences on functional currencies are recorded directly in shareholders’ equity as cumulative translation adjustments, net of any related deferred taxes, if applicable.

Any outstanding balances in foreign currencies arising from foreign currency transactions other than the functional currencies are translated at end of period exchange rates. Revenues and expenses are translated using the exchange rate at the date of the transaction. The resulting exchange differences are recorded in the statements of income.

(d) Non-life insurance and reinsurance

Premiums: Premiums from short-duration insurance and reinsurance contracts are recorded as written and are earned primarily on a pro-rata basis over the period that the related insurance or reinsurance coverage is in effect. However, for those contracts for which the period of risk differs significantly from the contract period, premiums are earned over

F-11

the period of risk in proportion to the amount of insurance or reinsurance protection provided. The unearned premium reserve represents the portion of the premiums written relating to the unexpired terms of coverage. Such reserves are computed by pro-rata methods based on statistical data or reports received from ceding companies.

In a typical reporting period, Converium generally earns a portion of the premiums written during that period together with premiums that were written during earlier periods. Likewise, some part of Converium’s premiums written will not be earned until future periods. Converium allocates premiums written but not yet earned to an unearned premium reserve, which represents a liability on Converium’s balance sheet. As time passes, the unearned premium reserve is gradually reduced and the corresponding amount is released through the income statement as premiums earned. Converium’s premium earned and written estimates are regularly reviewed and enhanced as information is reported by clients and Converium is able to refine estimates and assumptions. Converium’s estimation procedures are also affected by the timeliness and comprehensiveness of the information its clients provide to us. Premium for a retroactive reinsurance contract is recognized as earned at the inception of the contract.

Deferred policy acquisition costs: Acquisition costs, principally representing commissions and brokerage expenses, premium taxes and other underwriting expenses, net of allowances from retrocessionaires, which vary with and are directly related to the production of new business, are deferred and amortized over the period in which the related written premiums are earned.

Losses: Losses and loss expenses are charged as incurred. Unpaid losses and loss expenses represent the accumulation of estimates for ultimate losses based on reports and individual case estimates received from ceding companies. An amount is included for losses and loss expenses incurred but not reported (the “IBNR”) on the basis of past experience of Converium and its ceding companies. Converium does not discount its loss reserves, other than for settled claims with fixed payment terms.

The methods of determining such loss and loss expense estimates and establishing the resulting reserves are continually reviewed and updated and, as experience develops and new information becomes known, the reserves are adjusted as necessary. Resulting adjustments are reflected as current expense in the period in which they become known. Since the reserves are based on estimates, the ultimate settlement may vary from the amount provided.

Deferred charges reinsurance assumed: The excess of the estimated ultimate claims payable over the premiums received with respect to retroactive property and casualty reinsurance contracts is established as a deferred charge which is subsequently amortized over the expected claim payment period. The timing and amount of expected future losses are re-estimated periodically. Deferred charge balances are adjusted accordingly on a retrospective basis via a cumulative adjustment with the net effect included in the amortization expense in the period of change, which is reflected in losses and loss adjustment expenses. Deferred charge balances are included in other assets in the balance sheet.

Participations at Lloyd’s: Participations in syndicates operating at Lloyd’s of London are accounted for using the periodic method. Converium recognizes its proportionate share of the syndicates insurance and reinsurance premiums as revenue over the policy term, and claims, including an estimate of claims incurred but not reported, are recognized as they occur. On the closure of an underwriting year, typically three years after its inception, syndicates reinsure all remaining unsettled liabilities into the following underwriting year, a mechanism known as reinsurance to close (“RITC”). If Converium has increased its participation from one year of account to the next, RITC paid is eliminated, as a result of this offset, leaving an element of the RITC received. This reflects the fact that the Company has assumed a greater proportion of the business of the syndicates. If the Company has reduced its participation from one year of account to the next, the RITC received is eliminated, leaving an element of RITC paid. This reflects the reduction in the Company’s exposure to risks previously written by the syndicates.

(e) Life reinsurance

Recognition of reinsurance revenue and related expenses: Premiums from short-duration life reinsurance contracts are recognized as revenue over the remaining contract period in proportion to the amount of reinsurance protection provided. Premiums from long-duration life reinsurance contracts are recognized as revenue in a manner consistent with the underlying reinsured contracts. Benefits and commissions are provided against such revenue to recognize profits over the estimated life of the reinsurance contract.

Deferred policy acquisition costs: Acquisition and commission costs incurred in acquiring new business are deferred. Deferred policy acquisition costs are amortized over the expected life of the contracts as a constant percentage of expected premiums. Expected premiums are estimated at the effective date of the contract and are consistently applied throughout the life of the contract unless a premium deficiency occurs.

F-12

Converium Holding AG and Subsidiaries

Notes to the consolidated financial statements

Deferred policy acquisition costs are subject to recoverability testing at the time of contract issue and at the end of each reporting period.

Future life benefits reserves and contract deposits: Liabilities for future life benefit reserves and contract deposits are estimated on bases consistent with those used for the original policies issued and with the terms of the reinsurance contracts.

(f) Retrocessions

Converium cedes reinsurance to retrocessionaires in the normal course of business. The cost of short-duration retrocessional contracts is amortized over the contract period in proportion to the amount of reinsurance protection provided consistent with the underlying assumed contracts. The cost of long-duration retrocessional contracts is amortized over the estimated life of the underlying assumed contracts. The difference, if any, between the amounts paid for the retrocessional contract and the amount of the liability for contract benefits relating to the underlying reinsured contracts is part of the estimated cost to be amortized. Reinsurance is recorded gross in the balance sheet. Reinsurance assets include the balances due from retrocessionaires for paid and unpaid losses and loss expenses, ceded unearned premiums and ceded future life benefits. Amounts recoverable from retrocessionaires are estimated in a manner consistent with the liabilities associated with the reinsured contract.

As part of Converium’s risk management process Converium regularly evaluates the recoverability of its reinsurance assets taking into account all public domain information including the current rating of its retrocessionaires. Converium establishes an allowance for potentially uncollectible reinsurance recoverables from retrocessionaires. Converium immediately charges operations for any recoverable balances that are deemed to be uncollectible. Collateral and other offsets are considered in determining the size of the allowance or expense.

(g) Deposit accounting transactions

In accordance with SFAS 113 and SOP 98-7 reinsurance contracts are assessed to determine if underwriting risk, defined as the reasonable possibility of a significant variation in the amount of payments and the reasonable possibility that the reinsurer will realize a significant loss and timing risk, defined as the reasonable possibility of a significant variation in the timing of cash flows, is transferred by the ceding company. In the event that a transaction does not meet the risk transfer requirements, the transaction will be accounted for under deposit accounting. A deposit asset or liability is recognized based on the consideration paid or received less any explicitly identified fees to be retained by the ceding or assuming company. Deposits for contracts that transfer only significant underwriting risk are subsequently measured based on the period of coverage until a loss is incurred, after which the present value of expected future cash flows under the contract is also accrued. Deposits for contracts that transfer only timing risk, or deposits for contracts that transfer neither significant timing nor underwriting risk, are accounted for using the interest method. Future cash flows are estimated to calculate the effective yield and revenue and expense are recorded as interest income or expense. The effect of contracts with indeterminate risk is not included in the determination of net income until sufficient information becomes available to reasonably estimate the impact. Any fee is recognized as other income/expense over the coverage period of the policy and is not recorded as a deposit asset/liability. Changes in the deposit amount are recorded in the statement of income as a loss or loss expense.

(h) Invested assets

The majority of Converium’s fixed maturities and equity securities are classified as available-for-sale; these investments are carried at fair value. Fixed maturities for which Converium has the intent and ability to hold to maturity are classified as held-to-maturity. Held-to-maturity securities are carried at amortized cost, if purchased, or carrying value, if transferred from the available-for-sale category to the held-to-maturity category. The difference between the fair value and amortized cost at the date of transfer of such securities is amortized over the life of the respective securities. The carrying value of transferred securities is the fair value at the date of transfer less amortized net unrealized gains.

Unrealized gains or losses on investments carried at fair value are recorded in other comprehensive income, net of deferred income taxes.

When declines in values of securities below cost or amortized cost are considered to be other than temporary, an impairment charge is recorded as a realized capital loss in the statement of income for the difference between cost or amortized cost and estimated fair value.

F-13

Realized gain or loss on disposals is based on the difference between the net proceeds received and the cost or amortized cost of the investment using the specific identification method. The amortization of premium and accretion of discount on investments in fixed maturities is computed using the effective interest method and is recorded in current period income. Dividends on equity securities are recorded as revenue on the ex-dividend date, the date that the dividends become payable to the holders of record.

Real estate held for investment, which is included in the balance sheet under the caption, “Other investments”, is recorded at depreciated cost and is depreciated on a straight-line basis over thirty years. The gain or loss on disposal is based on the difference between the proceeds received and the carrying value of the investment.

Converium has an interest in certain partnerships which are engaged exclusively in making investments in direct private equity, private equity funds and hedge funds. These investments are carried at fair value as determined by the fund manager, with changes in fair value being recorded as other income or loss. Investments in hedge funds are recorded at fair value with changes in net asset value flowing through other comprehensive income as a separate component in shareholders’ equity.

Short-term and other investments are recorded at cost which approximates fair value. Short-term investments are those with a maturity of greater than three months but less than one year from date of purchase.

The Funds Withheld Asset is carried at the principal balance plus accrued interest.

(i) Other-than-temporary impairments

Based on quantitative and qualitative factors, the Company reviews at least quarterly individual debt and equity securities classified as held-to-maturity or available-for-sale, of whether or not there is an indication that a decline in fair value below the investment security’s carrying value is considered other-than-temporary.

For securities expected to be sold, an other-than-temporary charge will be recognized if the Company does not expect the fair value to recover prior to the expected date of sale.

Converium has outsourced investment management to recognized and experienced professional funds managers that also operate within the specific investment guidelines of the Company.

(j) Derivative instruments

Derivative financial instruments include swaps, futures, forwards and option contracts, which all derive their value from underlying interest, foreign exchange rates, commodity values or equity prices. Derivatives are subject to various risks similar to those related to the underlying financial instruments, including market, credit and liquidity risk.

Derivative instruments are recognized on the balance sheet at fair value with fair values based on quoted market prices or pricing models using current market rates. The recognition of changes in the fair value of a derivative depends on its intended use. Derivatives and other financial instruments are used to hedge exposures or modify exposures to interest rate and foreign currency risks. Changes in the fair value of derivatives used in hedging activities are, depending on the nature of the hedge, either recognized in earnings together with the change in fair value of the hedged item attributable to the risk being hedged, or recognized in other comprehensive income until the hedged item affects earnings. For all hedging activities, the ineffective portion of a derivative’s change in fair value is immediately recognized through earnings. Derivatives not used in hedging activities are adjusted to fair value through earnings.

Embedded derivatives in insurance contracts and investment contracts are separated from their host contracts and accounted for as derivative instruments under SFAS No.133, “Accounting for Derivative Instruments and Hedging Activities”.

F-14

Converium Holding AG and Subsidiaries

Notes to the consolidated financial statements

Converium utilizes foreign exchange swaps as part of its overall currency risk management. The objective is to manage the liquidity situation of Converium’s entities in various currencies.

(k) Obligation to repurchase securities

Sales of securities under agreements to repurchase are accounted for as collateralized transactions and are recorded at their contracted repurchase amount plus accrued interest. Converium minimizes the credit risk that counterparties to transactions might be unable to fulfill their contractual obligations by monitoring customer credit exposure and collateral value and generally requiring additional collateral to be deposited with Converium when deemed necessary.

(l) Cash and cash equivalents

Cash amounts represent cash on hand and demand deposits. Cash equivalents are short-term, highly liquid investments with original maturities of three months or less.

(m) Fixed assets

Fixed assets, which are included in the balance sheet under the caption “Other assets”, are carried at cost less accumulated depreciation and any necessary write-downs for impairment. The costs of fixed assets are depreciated principally on a straight-line basis over the following estimated useful economic lives: furniture and fixtures five to ten years; computer equipment and software three to five years. Maintenance and repair costs are charged to income as incurred; costs incurred for major improvements are capitalized and depreciated. Gains and losses on disposal of fixed assets are based upon their carrying volume.

(n) Goodwill and intangible assets

Identifiable intangible assets with finite lives are amortized on a straight-line basis over their estimated useful lives. The Company evaluates both the expected useful life and the recoverability of its intangible assets whenever changes in circumstances warrant. In accordance with SFAS 142, the Company reviews the carrying value of goodwill related to all of its investments for any impairment on at least an annual basis. If it is determined that an impairment exists, the excess of the unamortized balance over the fair value of the intangible asset will be charged to income at that time. If it has been determined that the estimated useful life of the intangible asset has changed the remaining unamortized balance of the intangible asset will be amortized on a straight-line basis over the newly determined expected useful life of the asset.

(o) Recognition and measurement of long-lived assets

Converium periodically reviews its long-lived assets to determine potential impairment. If the recoverable amount is less than the carrying amount of the asset, an impairment loss is recognized. The recoverable amount is measured using the sum of the asset’s undiscounted estimated future cash flows expected to arise from the use of the asset and from its disposal at the end of its useful life. The impairment loss is measured as the difference between the carrying amount of the asset and its fair value. Fair value is defined as the market price less cost of disposal. If the market price is not available, fair value is estimated based on the present value of future cash flows.

(p) Income taxes

Taxes on income are accrued in the same period as the revenues and expenses to which they relate. Deferred income taxes are provided for all temporary differences that are based on the difference between financial statement carrying amounts and the income tax bases of assets and liabilities, tax effected using the enacted local income tax rates. The income tax basis of an asset or liability is calculated in accordance with the rules for determining taxable income established by the local taxation authorities. For a particular asset or liability, this may result in a deferred tax asset in one country but a deferred tax liability in another. In addition, a deferred tax asset is established for net operating loss carryforwards.

As required under SFAS No.109, “Accounting for Income Taxes” (“SFAS No.109”) Converium is required to assess if it is more likely than not that some or all of the net deferred tax assets will not be realized. A valuation allowance is recorded to reduce net deferred tax assets to the amount that is expected to be realized. Historical losses are considered among other factors in making this assessment. As a result of significant historical losses, a full valuation allowance was established against Converium AG’s net deferred tax assets to reflect the continued net loss position of the Company. Converium AG may offset future taxable income against the existing net operating losses carried forward, resulting in no tax expense on such income until such time as the net operating losses are utilized or expire, or the valuation allowance is released.

The Company does not affirmatively apply the exception to the recognition of deferred taxes under Accounting Principles Board Opinions No.23 (APB23), “Accounting for Income Taxes – Special Areas” and therefore is required under SFAS No.109 to provide for taxes on the undistributed earnings of its foreign subsidiaries and foreign corporate joint ventures. However, due to various factors, including no positive undistributed earnings in any foreign subsidiaries or joint ventures and the availability of the participation exemption, no provision for taxes is made on earnings or other outside basis differences of the foreign subsidiaries and joint ventures.

F-15

(q) Employee benefits

Converium provides defined benefit plans for its European employees. The assets of these plans are principally held separately from Converium’s general assets in trustee-administered funds.

In September 2006, the FASB issued SFAS 158 “Employers Accounting for Defined Benefit Pension and Other Post Retirement Plans ” (SFAS 158). The Company adopted SFAS 158 prospectively on December 31, 2006. In accordance with the requirements of SFAS 158, the funded status of plans was determined as of the end of the fiscal year. Any over-funded or under-funded status relating to defined benefit plans is recognized as an asset or liability respectively. Contributions to defined contribution pension plans are charged to income as they become due. See Note 13 for further information on the impact of SFAS 158 on the Company.

Converium recognizes the expense related to incentive plans over the relevant performance period.

(r) Stock option accounting

On January 1, 2006, Converium adopted SFAS 123 (revised 2004), “Share-Based Payment ” (SFAS 123(R)). In accordance with the requirements of SFAS 123(R), Converium uses the modified prospective method, and recognizes grants of employee stock options at the fair value of the award on the grant date. The fair values of all stock options granted by the Company are determined using the Black-Scholes-Merton model (B-S-M Model). The adoption of SFAS 123(R) did not have a material impact on the financial position or results of operations.

(s) Restructuring costs

Restructuring costs relating to employee service termination are measured initially at the communication date based on the fair value of the liability as of the termination date. Converium recognizes the liability ratably over the future service period of employees. Restructuring costs associated with changing the provisions of an existing lease are recognized and measured at fair value in the period in which the liability occurs.

(t) Contingencies

In accordance with SFAS No.5 “Accounting for Contingencies”, management evaluates each contingent matter separately. A loss is recorded if probable and reasonably estimable. Management establishes reserves for these contingencies at its “best estimate”, or, if no one number within the range of possible losses is more probable than any other, the Company records an estimated reserve at the low end of the range of losses.

(u) New accounting pronouncements

The following new standards have been or will be required to be adopted by Converium in the future:

SFAS 155, “Accounting for Certain Hybrid Instruments”

In February 2006, the FASB issued SFAS 155, “Accounting for Certain Hybrid Instruments” (SFAS 155). This statement amends SFAS 133, “Accounting for Derivative Instruments and Hedging Activities and SFAS 140, “Accounting for Transfers and Servicing of Financial Assets and Extinguishment of Liabilities”. The standard allows financial instruments that have embedded derivatives to be accounted for as a whole (eliminating the need to bifurcate the derivative from its host contract) if the holder elects to account for the investment on a fair value basis. SFAS 155 also clarifies and amends certain other provisions in SFAS 133 and SFAS 140. This statement is effective for all financial instruments acquired or issued in fiscal years beginning after September 15, 2006. This guidance is currently not expected to have a material impact on the Company’s results of operations and financial position.

SFAS 157 “Fair Value Measurements”

In September 2006, the FASB issued SFAS 157 “Fair Value Measurements” (SFAS 157). This standard provides enhanced guidance for using fair value to measure assets and liabilities. SFAS 157 is effective for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The Company is currently in the process of evaluating the effect that the adoption of SFAS 157 will have on its results of operations and financial position.

The Company adopted SFAS 158 on December 31, 2006. See (q) Employee benefits.

SFAS 159, “The Fair Value Option for Financial Assets and Financial Liabilities ”

In February 2007, the FASB issued SFAS 159 “The Fair Value Option for Financial Assets and Financial Liabilities” (SFAS 159). The fair value option established by SFAS 159 permits all entities to choose to measure eligible items at fair value at specified election dates. A company shall report unrealized

F-16

Converium Holding AG and Subsidiaries

Notes to the consolidated financial statements

gains and losses on items for which the fair value option has been elected in earnings at each subsequent reporting date. The fair value option may generally be applied instrument by instrument, is irrevocable, and, is applied only to entire instruments and not to portions of instruments. SFAS 159 becomes effective for financial years beginning after November 15, 2007. Converium is in the process of determining the impact of SFAS 159.

FASB Interpretation No. FIN 48, “Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No.109”

In June 2006, the FASB issued FASB Interpretation No. (FIN) 48, “Accounting for Uncertainty in Income Taxes”, which clarifies the accounting for uncertainty in income taxes recognized in financial statements in accordance with SFAS No.109, “Accounting for Income Taxes”. FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This interpretation requires that the impact of a tax position is recognized and measured in the consolidated financial statements, if that position is more likely than not of being sustained in an audit, based on the technical merits of the position. FIN 48 also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods and disclosure. The new guidance is applicable for periods beginning after December 15, 2006 and is not expected to have a material impact on the Company’s financial condition.

FASB Staff Position (“FSP”) FAS 123(R)-5 “Amendment of FASB Staff Position SFAS 123(R)-1”

In October 2006, the FASB issued FSB SFAS 123(R)-5, “Amendment of FASB Staff Position SFAS 123(R)-1”, which addresses whether a modification of an instrument in connection with an equity restructuring should be considered a modification for the purposes of applying SFAS 123(R)-1. This FSP becomes effective for fiscal years beginning after October 10, 2006 and is currently not expected to have a material impact on the Company’s results of operations and financial position.

FASB Staff Position (“FSP”) FIN 46(R)-6 “Determining the Variability to be Considered in Applying FASB Interpretation No. 46(R)”

In April 2006, the FASB issued FSP FIN 46(R)-6 “Determining the Variability to be Considered in Applying FASB Interpretation No. 46(R)”. This FSP addresses how an entity should determine the variability when applying FIN 46(R). The variability will determine if an entity is a variable interest entity as well as the amounts of any expected losses or residual returns. This FSP is effective for reporting periods commencing after July 15, 2006. The Company is currently in the process of evaluating the impact that this FSP will have on its results of operations and financial position.

SEC Staff Accounting Bulletin 108 (SAB 108) –“Considering the Effects of Prior Year Misstatements when Qualifying Misstatements in Current Year Financial Statements”

In September 2006, the SEC staff issued SAB 108 –“Considering the Effects of Prior Year Misstatements when Qualifying Misstatements in Current Year Financial Statements”. SAB 108 was issued to eliminate the diversity of practice surrounding how public companies quantify financial statement misstatements. At December 31, 2006, the date of required adoption, this new guidance did not have a material impact on the results of operations and financial positions.

2. Discontinued operations

On December 13, 2006, the Company sold all of its outstanding shares of capital stock of Converium Holdings (North America) Inc. representing its North American operations to National Indemnity Company, a Berkshire Hathaway company for a total consideration of USD 295.0 million, including the Senior Note with a principal amount of USD 200.0 million and total cash proceeds of USD 95.0 million.

The Surplus Contribution Note between Converium Holding AG, Switzerland and Converium Reinsurance (North America) Inc. with a principal amount of USD 150.0 million and accrued interest amounting to USD 33.3 million has been sold and assigned to the buyer for a consideration of one US dollar.

As outlined in the transition service agreement, the Company will provide certain services to National Indemnity Company, however; estimated revenue is considered not material.

The Company reflects the sale of its North American operations as discontinued operations in accordance with Statement of Financial Accounting Standard No.144, “Accounting for the Impairment or Disposal of Long-lived Assets”. In the fourth quarter of 2006, a total loss on the transaction of USD 190.1 million, including transaction costs, was recognized.

3. Restructuring costs

For the year ended December 31, 2006, Converium incurred a restructuring benefit of USD 0.2 million due to the release of restructuring accruals as compared with expenses of USD 12.1 million for the same period in 2005. In 2005, the reduction in overall business volume required organizational changes and an adjustment to Converium’s global cost base including employee terminations and closure of smaller offices. In 2004 Converium recorded restructuring costs of USD 0.2 million.

4. Foreign currency translation and transactions

Table 4.1 summarizes the principal exchange rates, which have been used for translation purposes (US dollar per foreign currency unit). Net realized (losses) gains on foreign currency transactions, which are included in the other (loss) income line of the consolidated statements of income (loss), were USD (1.7) million, USD (0.5) million and USD (5.8) million for the years ended December 31, 2006, 2005 and 2004, respectively.

5. Segment information

The primary measure of segment information, is segment income (loss), defined as income (loss) before other income (loss), interest expense, impairment of goodwill, amortization of intangible assets, restructuring costs and income taxes.

Standard Property & Casualty Reinsurance: General Third Party Liability, Motor, Personal Accident (assumed from non-life insurers) and Property.

Specialty Lines: Agribusiness, Aviation & Space, Credit & Surety, Engineering, Marine & Energy, Professional Liability and other Special Liability and Workers’ Compensation.

Life & Health Reinsurance: Life & Disability and Accident & Health.

In addition to the three segments’ financial results, the Corporate Center carries certain administration expenses, such as costs of the Board of Directors, the Global Executive Committee and other corporate functions as well as other expenses not allocated to the operating segments.

The accounting policies of the segments are the same as those described in the summary of significant accounting policies. Converium accounts for inter-segment revenues and transfers as if the transactions were with third parties at current market prices.

At December 31, 2005 real estate held for investment of USD 144.6 million, net of accumulated depreciation of USD 9.7 million, consisted primarily of investments in residential and commercial rental properties located in Switzerland, acquired in late 2001 from subsidiaries of Zurich Financial Services (“ZFS”). These properties were sold in the second half of 2006. The fire insurance value of Converium’s fixed assets totaled USD 35.6 million at December 31, 2006 as compared with USD 128.2 million at December 31, 2005, which also included fire insurance values of real estate held for investments.

There are no investments in any entity in excess of 10% of shareholders’ equity at December 31, 2006 and 2005, other than investments issued or guaranteed by the US or sovereign governments or their agencies.

Converium utilizes foreign exchange swaps as part of its overall currency risk management. The objective is to manage the liquidity situation of Converium’s entities in various currencies. There were no foreign exchange swaps outstanding at December 31, 2006 or 2005.

7. Goodwill and other intangible assets

Included in other assets was goodwill of USD 49.2 million and USD 49.5 million at December 31, 2006, and 2005, respectively. At December 31, 2006 and 2005 the value of the amortizable intangible asset was nil.

Investment in GAUM

In March 2003, upon receipt of all regulatory approvals, Converium finalized an agreement to acquire a 25% stake in GAUM, a leading international commercial and general aviation underwriting agency, as a part of its strategy to strengthen its long-term position in the aviation and space line of business. Under the terms of the sale and purchase agreement, Converium paid an initial consideration of GBP 14.2 million (USD 22.4 million) and is additionally obligated to pay deferred consideration associated with the underlying performance of GAUM’s in force business. In view of a capped limit on deferred consideration, the maximum amount payable by Converium for the 25% stake in GAUM is GBP 20.8 million (USD 32.7 million). In February 2004, Converium AG finalized a Sale and Purchase Agreement with Royal and Sun Alliance (“RSA”) to acquire a further 5.1% stake in GAUM, which increased its overall stake in GAUM to 30.1%.

An annual goodwill impairment test was carried out at December 31, 2006, and 2005 in respect of the 30.1% investment in GAUM and no impairment was required. At December 31, 2006 and 2005, the carrying value of goodwill associated with the 30.1% stake in GAUM was GBP 13.1 million (USD 23.4 million) and GBP 13.2 million (USD 23.6 million), respectively.

Converium will continue to reassess whether any impairment of goodwill is warranted as and when there is a change in current business circumstances, including termination and extension of the current fronting arrangements with Munich Re and National Indemnity which is due in 2007.

In the light of the S & P rating downgrade in 2004 and the need for subsequent fronting agreements with Munich Re and National Indemnity in order to sustain the aviation business from GAUM, Converium’s management reassessed the remaining useful life of the other intangible asset. The remaining useful life was determined to be less than one year, and the other intangible asset balance as at December 31, 2004 of GBP 11.2 million (USD 20.6 million) was fully amortized in 2005 giving rise to a USD 21.5 million charge for the year ended December 31, 2005. The intangible asset related to established customer relationships of GAUM and was initially intended to be amortized over a useful life of ten years.

MDUSL Investment

As of December 31, 2006 and December 31, 2005, goodwill was USD 20.0 million related to Converium AG’s 49.9% strategic investment in the Medical Defence Union Services Ltd (“MDUSL”). Converium conducts a yearly impairment test of the MDUSL investment. This business continues to perform in line with management’s expectations. No impairment was recognized for the years ended December 31, 2006 and 2005.

See Note 17 and 25 for additional information on GAUM and the Medical Defence Union (the “MDU”).

8. Losses and loss expenses

Significant delays occur in the notification of claims and a substantial measure of experience and judgment is involved in assessing outstanding liabilities, the ultimate cost of which cannot be known with certainty as of the balance sheet date. The reserve for losses and loss expenses is determined on the basis of information currently available; however, it is inherent to the nature of the business written that the ultimate liabilities may vary as a result of subsequent developments.

¹		The loss and loss expenses incurred includes USD 114.2 million, USD 178.3 million and USD 128.0 million of loss and loss expenses included in the Life & Health Reinsurance segment for the years ended December 31, 2006, 2005 and 2004, respectively.

²		Figures for 2005 and 2004 are as originally reported. Loss and loss expenses incurred and loss and loss expenses paid from discontinued operations were USD 55.8 million and USD 924.1 million and USD 948.1 million and USD 1,066.3 million for 2005 and 2004, respectively.

Prior years’ favorable net loss expenses incurred in 2006 of USD 145.2 million were primarily driven by net favorable development of prior years’ loss reserves of USD 102.8 million, and the reversal of reserves relating to prior years’ premium accruals in the amount of USD 42.4 million.

F-25

development of prior years’ loss reserves of USD 30.7 million primarily related to the Property line of business of USD 73.3 million, partially offset by net adverse development of prior years’ loss reserves within the Motor and General Third Party Liability lines of business of USD 25.0 million and USD 23.4 million, respectively. The Specialty Lines segment was positively impacted by net favorable development of prior years’ loss reserves of USD 55.3 million primarily related to the Aviation & Space line of business of USD 57.5 million.

The reserves for certain losses and loss expenses, such as those for settled claims with fixed payment terms, represent the present value estimates of the ultimate cost of all losses incurred but not paid through December 31 of each year. Deferred charges relating to retrospective reinsurance and structured settlements totaling USD 24.8 million, USD 31.2 million and USD 38.0 million as of December 31, 2006, 2005 and 2004, respectively, are as a result included in other assets.

Impact of property catastrophe losses

The year ended December 31, 2006 exhibited insignificant natural catastrophe activity with total incurred losses of USD 10.5 million. There were no individual large losses, defined as those in excess of USD 10.0 million or more of net incurred losses to Converium.

This was in contrast to the year ended December 31, 2005, which exhibited significant natural catastrophe large losses totaling USD 149.2 million: Winter Storm Erwin (USD 32.5 million), Continental European Floods (USD 24.8 million), Hurricane Katrina (USD 33.2 million), Hurricane Rita (USD 14.1 million) and Hurricane Wilma (USD 44.6 million). In 2004, Converium’s large natural catastrophe losses included hurricanes in the US and the Caribbean, the Japanese typhoons and the tsunami in the Indian Ocean, with a total net impact of USD 98.4 million.

September 11^th terrorist attacks

The September 11^th terrorist attacks in the United States represented one of the largest loss events in the insurance industry’s history. In 2001, Converium recorded gross losses and loss expenses of USD 692.9 million arising out of the terrorist attacks (including losses from our subsequently sold North American operations). These losses are capped through an agreement with ZFS. Converium recorded losses and loss expenses, net of retrocessional recoveries and the cap from ZFS through its subsidiaries, were reduced from USD 289.2 million to USD 231.0 million, following the sale of its North American operations. Converium will be exposed to the risk of non-payment of ZFS’ units and Converium is exposed to credit risk from these subsidiaries of ZFS. Converium is not exposed to potential non-payments by retrocessionaires for these events in excess of the cap. In 2006, 2005 and 2004, there was no additional development in net reserves for the September 11^th terrorist attacks.

As of December 31, 2006, Converium recorded gross and net incurred losses and loss expenses related to the September 11^thterrorist attacks as follows:

Table 8.2

F-26

Converium Holding AG and Subsidiaries

Notes to the consolidated financial statements

Included in the reinsurance recoveries above are USD 23.4 million due from ZFS and subsidiaries.

Certain arrangements with ZFS as described herein provide protection against potential adverse loss development on the September 11^th terrorist attacks for Converium AG and Converium Rückversicherung (Deutschland) AG above the initial loss amounts recorded of USD 231.0 million, net of retrocessional reinsurance recoveries.

Converium AG’s exposure under the Quota Share Retrocession Agreement (see Note 16) is limited for “Extraordinary Events”. The agreement limits Converium AG’s losses arising out of any “Extraordinary Event” to USD 220.0 million and the parties have agreed that the September 11^th terrorist attacks are an “Extraordinary Event” and that the USD 220.0 million limit applies to losses arising out of the September 11^th terrorist attacks. Because Zurich Insurance Company (“ZIC”) and Zurich International Bermuda Ltd (“ZIB”), wholly owned subsidiaries of ZFS, retain losses in excess of the limit, ZFS will be responsible for non-payment, if any, by the retrocessionaires with regard to losses arising out of the September 11^th terrorist attacks in excess of the USD 220.0 million limit.

ZIC will indemnify Converium Rückversicherung (Deutschland) AG for losses arising out of the September 11^th terrorist attacks in excess of USD 11.0 million, net of retrocessional reinsurance recoveries.

Asbestos and environmental exposures

As of December 31, 2006 and 2005, Converium had reserves for environmental impairment liability and asbestos-related claims of USD 49.2 million, respectively, for each year. Converium’s survival ratio (calculated as the ratio of reserves held, including IBNR, over claims paid over the average of the last three years) for asbestos and environmental reserves was 13.8 years at December 31, 2006 and 14.1 years at December 31, 2005.

9. Guaranteed Minimum Death Benefit (GMDB)

Converium assumed certain retrocession liability with regard to Guaranteed Minimum Death Benefit (GMDB) features attached to variable annuity policies written in the United States. These treaties are all in run-off and cover in total 1.1 million policies that were issued mainly in the late 1990’s and that incorporate various benefit types originating from different primary insurers. Claims occur in the event of death if a policy is in-the-money, which means that the GMDB exceeds the account balance. Under these circumstances, the difference between the GMDB and the account balance or the GMDB and the cash surrender value becomes due, depending on the definition of the underlying reinsurance agreements.

The following types of Guaranteed Minimum Death Benefits are covered:

–

Return of premium: The GMDB is the amount of total deposits adjusted for partial withdrawals, if any.

–

Ratchet: After a given number of years, the GMDB is adjusted to the current account balance, if greater. Most common is a 1-year ratchet, meaning that the GMDB is adjusted annually on the policy’s anniversary date.

–

Rollup: The GMDB increases each year from the initial premium adjusted for later deposits and partial withdrawals by a fixed percentage. Rollup guarantees reinsured under Converium’s agreements grant an annual accumulation percentage between 3% and 7%. In many products, especially for higher rollup percentages, an upper limit applies (e.g. 200% of the paid policyholder premium adjusted for later deposits and partial withdrawals).

–

Reset: After a given number of years, the GMDB is adjusted to the current account balance. This means that the GMDB can be reduced but often not below the paid-up premium (adjusted for later deposits and partial withdrawals).

–

Combinations of the above.

Guarantees that increase over the time are, for a majority of the assumed business, only applied up to a certain age (e.g. 85). For the majority of the portfolio, a maximum death benefit age exists and as a consequence, Converium will be off the risk afterwards.

Converium does not hold any contract holder funds. These assets remain with the originating ceding companies.

The GMDB liability is determined each period based on the information provided by Converium’s ceding companies. The current account value, the guaranteed death benefit and details of the covered benefit types are taken into consideration for the evaluation of the net amount at risk (NAR) and the expected future liability. The liability according to SOP 03-1 is estimated at the end of the reporting period.

For the evaluation of the liabilities, Converium uses an actuarial model that considers 1,000 stochastically generated investment performance scenarios. The mean performance assumed for equities is 9.6% and the mean performance for other investment types such as bonds and cash deposits varies between 4.8% and 5.7%. The corresponding volatility assumptions are 18.3% and 1.5% to 2.2%, respectively. The discount rate used in the model is stochastically generated in

F-27

line with the other investment scenarios and takes into consideration the current yield level. It is assumed to be an average of 5.7% over the long run. The mortality assumption is 100% of the Annuity 2000 table. Lapse rates vary by duration and range from 6.5% to 20%. Partial withdrawals, either applied pro-rata or on a dollar-for-dollar basis according to the policy conditions, are also considered in the modeling.

The corresponding parameter, reflecting the on-average withdrawn amount of the account value, varies by duration and is assumed to range from 2.4% to 7.5% per annum.

As of December 31, 2006, the following values were estimated as described above:

Table 9.1

10. Retrocessional reinsurance and catastrophe protection

Retrocessional reinsurance

As of December 31, 2006 recoverables, including insurance and reinsurance balances receivable, from subsidiaries of ZFS totaled USD 12.5 million, or 0.7% of shareholders’ equity. There were no recoverables from any retrocessionaire that exceeded 10% of shareholders’ equity as at December 31, 2006 or 2005. Bad debt provisions of USD 11.3 million have been recorded for estimated uncollectible premiums receivable and reinsurance recoverables at December 31, 2006, compared with USD 28.1 million at December 31, 2005.

F-28

Catastrophe protection

On June 15, 2004, Converium AG announced the successful private placement of USD 100.0 million of floating rate notes issued by Helix 04 Limited (“Helix 04”), a Bermuda special purpose exempted company. By means of a counter-party contract with the issuer, the transaction provides Converium with fully collateralized second and subsequent event protection for North Atlantic hurricane, US earthquake, Japanese earthquake and European windstorm property catastrophe exposures. The notes are triggered only by second and subsequent events in any of the four peril regions during the five-year term of the transaction.

11. Debt

In December 2002, Converium Finance S.A. issued USD 200.0 million principal amount of non-convertible, unsecured, guaranteed subordinated notes (the “Guaranteed Subordinated Notes”). The Guaranteed Subordinated Notes are irrevocably and unconditionally guaranteed on a subordinated basis by both Converium Holding AG and Converium AG. The Guaranteed Subordinated Notes mature in full on December 23, 2032 and bear interest at the rate of 8.25% paid quarterly in arrears on March 15, June 15, September 15 and December 15. As of December 31, 2006, the carrying value of the Guaranteed Subordinated Notes was USD 194.1 million. The first call date is December 24, 2007.

Converium Holdings (North America) Inc. assumed USD 200.0 million principal amount of non-convertible, unsecured, unsub-ordinated Senior Notes (“the Senior Notes”) originally issued during October 1993 with a maturity date of October 15, 2023 and bearing an interest rate of 7.125%. The semi-annual interest payments were funded by Converium AG due to dividend restrictions of Converium Reinsurance (North America) Inc. The Senior Note was transferred to the National Indemnity company upon the sale of the North American operations (see Note 2).

Debt issuance costs and discounts were USD 5.9 million and USD 6.2 million at December 31, 2006 and 2005, respectively. Such costs are being amortized over the term of the related debt.

F-30

other affiliates, no deferred income tax expense has been reported for these entities.

Due to the reorganization of the Company the profit allocation from Switzerland to Bermuda had to be reduced. This change resulted in an increase of net deferred tax assets and the valuation allowance on net deferred tax assets respectively. Both developments have been presented in the table prior as changes in applicable tax rate and change in valuation allowance. In addition to the described development, the change in valuation allowance was impacted by movements in temporary differences and net operating losses in all jurisdictions.

Converium’s consolidated income tax expense for the year ended December 31, 2004 reflects an expense of USD 126.1 million related to the establishment of a valuation allowance against the net deferred tax assets at Converium AG. The effect was partially offset by an increase in deferred tax assets due to additional net operating losses related to the impairment of the carrying value of Converium AG’s participation in the former North American operations and general reserve strengthening.

As of December 31, 2006, Converium had total net operating losses carried forward of USD 1,040.5 million available to offset future taxable income of certain branches and subsidiaries. All of these net operating losses carried forward relate to Converium Rückversicherung (Deutschland) AG and Converium AG. Converium AG’s net operating losses expire in the years 2011 through 2013. The benefits of these carry-forwards are dependent on the generation of taxable income in those jurisdictions in which they arose and accordingly, a valuation allowance has been provided where management has determined that it is more likely than not that the carry-forwards will not be utilized.

Converium will continue to monitor its tax position and reassess the need for a full valuation allowance on its net deferred tax assets at each reporting period. Realization of the deferred tax asset related to net operating losses carried forward is dependent upon generating sufficient taxable income within specified future periods.

Converium’s deferred income tax assets and liabilities are reflected in table 12.3 below:

Notes to the consolidated financial statements

Included in the change in valuation allowance as of December 31, 2006 is a decrease of USD 8.8 million as a result of the fluctuation in foreign currency rates.

The current net income tax payable as of December 31, 2006 was USD 7.3 million. The current net income tax payable as of December 31, 2005 was USD 9.1 million as compared with a current net income tax receivable of USD 1.0 million at December 31, 2004.

13. Employee benefits

Personnel costs incurred for 2006, 2005 and 2004 were USD 82.8 million, USD 89.9 million and USD 87.4 million, respectively. The 2005 and 2004 amount includes costs related to the retention plans rolled out in September 2004 (see Note 14).

Defined benefit pension plans

Converium has defined benefit plans for its European employees. The employees of the North American operations which were sold in December 2006 participated in defined contribution plans which provided benefits equal solely to contributions paid plus investment returns. As at December 31, 2006 Converium no longer has defined contribution plans.

Employees of certain of Converium’s entities are covered under various defined benefit pension plans. Eligibility for participation in these plans is either based on completion of a specified period of continuous service or date of hire. Benefits are generally based on the employees’ years of credited service and average compensation in the years preceding retirement. Annual funding requirements are determined based on actuarial cost methods. The transition obligation (asset) was fully amortized at the end of 2003.

The Pension Fund of Converium AG (the “Fund”) is a foundation whose objective is to insure the personnel of Converium AG against the economic consequences of retirement, disability and death as provided by the statutory provisions of the plan rules. The Fund is a pension fund providing mandatory insurance as required by Swiss Federal Law and is supervised by the Canton of Zurich. The Fund’s pension plan is a “defined contribution plan” in accordance with Swiss Federal Law, but it does not meet the definition of a defined contribution plan pursuant to SFAS No. 87, “Employers’ Accounting for Pensions”, because of certain defined benefit elements required by Swiss Federal Law.

The overall goal of the plan is to maximize total investment returns to provide sufficient funding for present and anticipated future benefit obligations within the constraints of a prudent level of portfolio risk and diversification. Risk tolerance is established through careful consideration of plan liabilities, plan funded status and corporate financial condition. The investment portfolio contains primarily a diversified blend of equity and fixed income investments together with other asset classes, including real estate which are used to enhance long-term returns, while improving portfolio diversification. Investment risk is measured and monitored on a regular basis.

The assumptions about long-term rates of return on plan assets are based on the historical difference in performance between equities and government bonds. Historical markets are studied and long-term historical relationships between equities and fixed income securities are observed, consistent with the widely accepted capital market principle that assets with higher volatility generate a greater return over the long run. Current market factors such as inflation and interest rates are evaluated before long-term capital market assumptions are determined. The long-term portfolio return is established via a building block approach with proper consideration of diversification and rebalancing. Peer data and historical performance reviews are conducted as part of this process. See Table 13.7 for more information on the asset allocation mix in respect of the years ended December 31, 2006 and 2005.

The participants’ contributions to the Fund typically amount to between 7% and 11.5% of the coordinated annual salary (defined as base salary minus coordination amount of 30%) depending on the insured participant’s age and 7% of the annual incentive-based salary. By law, the employer’s contribution must at least equal the contribution of the participant. Converium AG’s contribution typically amounts to between 9% and 16% of the coordinated annual salary and 9% of the incentive-based salary. Converium AG’s contributions to the Fund amounted to CHF 4.2 million (USD 3.4 million) in 2006 and CHF 6.3 million (USD 5.1 million) in 2005.

In addition, Converium’s German operations Converium Rückversicherung (Deutschland) AG have a defined benefit scheme which is fully unfunded in accordance with German statutory law.

Converium uses a December 31 measurement date for all of its defined benefit plans.

Based on the funded status of defined benefit and other post retirement benefit plans as of December 31, 2006, the Company reported an increase in pension liability of USD 6.6 million, a reduction in other comprehensive income, net of tax of USD 4.9 million and a decrease of deferred income taxes of USD 1.7 million.

Employee retention plan

In September 2004, Converium adopted a retention plan for certain of its key employees in order to ensure the successful continuation of business operations and the orderly run-off of its formerly owned North American operations. The total cost of the program was USD 28.8 million, over a three year period with the last installment paid in January 2006. The continuing operations portion was USD 7.1 million and USD 11.6 million for 2005 and 2004, respectively. Included in the results for discontinued operations for 2006 is an accrual of USD 0.8 million for payments to certain North American employees following the finalization of the sale of the North American operations in December 2006. No further amounts are expected to arise.

(b) Share-based incentive plans

Share-based compensation plans include all plans under which shares or options to purchase shares are awarded. The grant of shares and options to purchase shares in Converium Holding AG is at the discretion of the Nomination and Remuneration Committee of the Board of Directors. The most significant of these are described in the following plans.

Employee Stock Purchase Plan

Annual Incentive Share Plan

Certain executives receive a minimum of 25% of their Annual Incentive Plan in the form of Converium shares. All employees may elect to receive up to 50% of their AIP in Converium shares. If these AIP shares are held for a three-year period, employees receive an additional share award equal to 25% of their AIP shares.

(c) Option-based incentive plans

Options are issued with an exercise price equal to the market value of the shares or ADSs on the grant date. 25% of the options vest immediately on the grant date and 25% vest each year thereafter or upon retirement. The options expire 10.5 years after the date of grant. Due to the sale of the North American operations as of December 13, 2006, un-vested grants for active North American employees forfeited as of the sale date. Any unexercised options will forfeit as of March 13, 2007.

Executive IPO option plan

In connection with the Transactions, Converium granted certain executives options to purchase shares in Converium Holding AG (the “Executive IPO Option Plan”). Under the Executive IPO Option Plan, 420,000 options to purchase shares in Converium Holding AG were awarded. The exercise prices were equal to the market value of the shares or ADSs on the grant date. Executive IPO Options are now fully vested and expire 10.5 years after the date of grant.

(d) Compensation expense

The compensation expense charged to income under the share-based incentive plans was USD 4.2 million, USD 5.0 million and USD 5.7 million in 2006, 2005 and 2004, respectively. As of December 31, 2006, there was USD 4.9 million of total unrecognized compensation cost related to non-vested shares and options; that cost is expected to be recognized over a period of 1.3 years.

(e) Cash used / received

Cash received from option exercise under all share-based payment arrangements for the years ended December 31, 2006 and 2005 was USD 4.5 million and USD 0.9 million, respectively. In order to fulfill its obligations under the various employee share plans Converium has repurchased shares on the open market. In 2007, Converium plans to continue repurchasing its own shares on the open market with an expected number between 500,000 and 700,000 shares. Cash used for this activity in years ended December 31, 2006, 2005 and 2004 amounts to USD 16.7 million, USD 1.5 million, and USD 6.5 million, respectively.

15. Shareholders’ equity

(a) Issued share capital

F-39

(b) Authorized share capital

At the Annual General Meeting on April 11, 2006 the shareholders resolved to extend the authority of the Board of Directors to increase the share capital until April 11, 2008.

At December 31, 2006, no shares were issued from the authorized share capital.

(c) Contingent share capital

Subsequent to the reduction of the nominal value of each of Converium’s shares in October 2004, its conditional capital is now for a number of four million shares of CHF 5 nominal value each, amounting to a maximum of CHF 20,000,000 pursuant to which up to four million shares can be issued upon exercise of conversion or option rights allotted in connection with bonds and other financial market instruments.

At December 31, 2006, no shares were issued from the contingent share capital.

(d) Dividend restrictions, reductions in the registered shares’ nominal value and capital and solvency requirements

Converium Holding AG is subject to legal restrictions on the amount of dividends it may pay to its shareholders under the Swiss Code of Obligations. The Swiss Code of Obligations provides that 5% of the annual profit must be allocated to the general reserve until such reserve in the aggregate has reached 20% of the paid-in share capital. Similarly, the Company laws of countries in which Converium entities operate may restrict the amount of dividends payable by such entities to their parent companies.

As of December 31, 2006, Converium Holding AG had 146,689,462 registered shares with a nominal value of CHF 5 each issued. Based on Swiss company law, Converium Holding AG is entitled to reduce the nominal value of its registered shares down to CHF 0.01 by a respective payment per share to its shareholders. Other than by operation of the restrictions mentioned above, the ability of Converium entities to pay dividends may be restricted or, while dividend payments per se may be legally permitted, may be indirectly influenced by minimum capital and solvency requirements that are imposed by insurance, bank and other regulators in the countries in which the entities operate as well as by other limitations existing in certain of these countries (e.g. foreign exchange control restrictions).

In Switzerland, insurance supervisory regulations require entities to fund their statutory reserves at a minimum level of 20% of net profits until the statutory reserve fund reaches an amount equal to 50% of the statutory share capital, including freely disposable reserves, if any. In the United States, restrictions on payment of dividends are imposed by the Insurance Commissioner of the state of domicile. In Germany, the minimum amount of statutory capital reserves required is 10% of the nominal value of the common stock. If the 10% criterion is met, dividends of up to 100% of current years’ surplus can be paid. If the 10% criterion is not met, dividends are limited to a maximum of 95% of current years’ surplus less the prior year loss carryover. Under German law, an entity’s executive board in consent with the supervisory board establishes the annual accounts and proposes on the distribution of the profits. The shareholders meeting (AGM) decides on this proposal.

16. Transactions with Zurich Financial Services

Quota Share Retrocession Agreement

In connection with the Transactions, the transfer of certain historical reinsurance business to Converium AG by ZIC and ZIB was affected by means of the Quota Share Retrocession Agreement effective July 1, 2001. The covered business consists of the business historically managed by Converium, which has an inception or renewal date on or after January 1, 1987 and consists of substantially all of the third party assumed reinsurance business written by ZIC and ZIB, under the “Zurich Re” brand name. The liabilities Converium AG assumed include all net unearned premiums, net losses and loss expenses and experience account balances relating to this business.

F-40

Converium Holding AG and Subsidiaries

Notes to the consolidated financial statements

Converium AG will receive the surplus remaining with respect to the Funds Withheld Asset, if any, after all liabilities have been discharged. In case the Funds Withheld Asset is not sufficient to cover the respective liabilities under the Funds Withheld Quota Share Retrocession Agreement with ZFS, Converium would have to meet those liabilities. Any surplus or any additional cash flows will be recorded in the financial statements in the period when realized. Any additional liabilities will be recorded in the financial statements when probable and reasonably estimatable. Additionally, ZFS has the right to prepay to Converium AG the full amount or a portion thereof of the Funds Withheld Asset prior to the termination of the agreement.

On December 23, 2005, an Amendment was agreed by the parties to the Quota Share Retrocession Agreements by way of which Section 7.01 – FW Cash Calls – was amended, with immediate effect, to provide, that Converium has the right, by giving sixty days prior written notice to ZFS, to ask for payment in cash on January 1 and July 1 of each calendar year, for the first time on July 1, 2006, of up to 25% of the total funds withheld sub-account balances, as per the most recent quarterly statements, under the respective agreements with ZFS. Furthermore, Converium has the right, at any time upon giving sixty days prior written notice, to ask for the residual balance of the funds withheld account falling below USD 100.0 million, to be paid in cash and in case Converium’s insurers financial strength rating as assigned by Standard & Poor’s is A or higher the latter amount is increased to USD 200.0 million.

Converium AG continues to administer the transferred business on behalf of ZIC and ZIB, which remain liable to the original cedents of the business. Additionally, Converium AG manages third-party retrocessions related to the business transferred. Converium bears the credit risk for uncollectible reinsurance balances excluding those related to the September 11^th terrorist attacks. Converium AG has a broad right of offset under the Quota Share Retrocession Agreement so that reinsurance balances owed to ZIC and ZIB may be offset against the Funds Withheld Asset account directly.

See Notes 6, 8, 17 and 20 for other transactions with ZFS and Note 25 for additional information.

17. Related party transactions

GAUM

In 2003, Converium finalized an agreement to acquire a 25% stake in GAUM, a leading international commercial and general aviation underwriting agency, as a part of its strategy to strengthen its long-term position in the Aviation & Space line of business. At that same time, Converium entered into a pool members’ agreement under which it became a member of the aviation and aerospace pools run by GAUM and its subsidiary, Associated Aviation Underwriters Inc.

In February 2004, Converium AG acquired a further 5.1% stake in GAUM from RSA increasing its overall stake to 30.1%.

F-41

agreements initially extended to September 30, 2005, however Converium has subsequently entered into a further series of fronting agreements with National Indemnity Company and Munich Re under similar terms and conditions which ensured Converium’s continued participation in the pool of GAUM through December 31, 2006. Converium also entered into a further agreement to extend the fronting agreement with the two counterparties until December 31, 2007 in respect of United States and Canadian sourced business and until June 30, 2007 in respect of business sourced from the rest of the world.

See Note 7 for additional information on GAUM goodwill and intangible assets.

MDU

The current terms of the MDU Shareholders’ Agreement require that Converium will provide a price concession, starting in 2010 and annually thereafter based upon a predetermined formula under which a price concession, which will be equal to 50% of the amount by which the present value profit, of a particular underwriting year, as calculated 10 years after that underwriting year has expired, exceeds a pre-agreed target expected present value profit. Converium has recognized a charge of USD 7.7 million and USD 9.0 million for 2006 and 2005 respectively in other (loss) income reflect-ing the current view of how the Company will settle this obligation.

At December 31, 2006 and December 31, 2005, the balance sheet obligation included in other liabilities was USD 16.7 million and USD 9.0 million respectively.

See Note 25 for additional information.

Converium Rückversicherung (Deutschland) AG leases office space from Oppenheim Immobilien Kapitalanlagegesellschaft mbH (Zürich Lebensversicherung Aktiengesellschaft (Deutschland) before the sale of the building). The lease term is for a period of ten years ending in 2008, with an option to renew for up to two additional ten-year terms. Lease payments have bi-annual rent escalations based on changes in local real estate price indices.

Parental Guarantees

In August of 2004, in order to retain certain US business, Converium AG endorsed for a number of selected cedents of Converium Reinsurance (North America) Inc. a parental guarantee with an option to novate business written for the 2003 and 2004 underwriting years. Some of these options to novate the business to Converium AG’s balance sheet were executed in the fourth quarter 2004. The remaining cedents did not execute the option and the business remained on Converium Reinsurance (North America) Inc.’s balance sheet. Due to the disposal of Converium’s North American operations to National Indemnity Company, Converium AG as the guarantor received from National Indemnity Company full indemnification of the potential outstanding liabilities. As of December 31, 2006, 2005 and 2004 these liabilities were USD 146.1 million, USD 95.7 million and USD 121.4 million, respectively.

MDU Put Option

On September 2, 2002, Converium AG granted MDU Investment Ltd (“MDUIL”) a put option which allows MDUIL, within the framework of the contractual agreement, to request that Converium AG subscribe to up to GPB 20 million preferred shares of MDUIL. The transaction would occur in tranches of one million shares at GBP 1 per share. At the same time, Converium AG granted the Medical Defence Union a call option that allows MDU to acquire in whole or in part the MDUIL shares held by Converium AG (or one of its subsidiaries).

Converium legal proceedings, claims and litigation

Converium Holding AG and Subsidiaries

Notes to the consolidated financial statements

Canada Life

On December 21, 2001, The Canada Life Assurance Company (“Canada Life”), brought an action against Converium Rück-versicherung (Deutschland) AG (“Converium Germany”) in the United States District Court of the Southern District of New York. Canada Life alleged that Converium Germany breached certain quota share retrocession agreements with Canada Life by failing to indemnify its full percentage of Canada Life’s September 11^th losses and by failing to post an USD 82.4 million letter of credit for its alleged liability pursuant to the ISA facilities’ underlying agreements. Converium Germany disputed this claim on the grounds that its liability under the pertinent contracts is limited and also raised other contract defenses. After litigation in the federal courts concerning jurisdictional issues, which Canada Life lost, Canada Life agreed to arbitration. The organizational meeting of the arbitrators took place on October 8, 2003. Since then, pursuant to an order by the arbitration panel, Converium Germany obtained a letter of credit of USD 65.97 million to be drawn down upon, if at all, should two of the three arbitrators issue an award in favor of Canada Life. A two-week hearing was conducted in July 2005. The arbitration panel since has rendered a final award in favor of Converium Germany. On May 9, 2006 (and later amended twice), Canada Life brought an action against the umpire of the arbitration panel and Converium Germany in the Ontario, Canada Superior Court of Justice seeking to set aside the final award. Canada Life alleges that the umpire was biased and unable to perform his duties. Canada Life also filed a Verified Petition against Converium Germany in the United States District Court of the District of New Jersey seeking, among other relief, to vacate the final award. Converium Germany recently filed a motion to dismiss the New Jersey action. On December 31, 2006 the letter of credit expired. The trial in the Canadian proceeding is scheduled to commence in September 2007.

Converium Germany has fully reserved this claim. However, arrangements entered into with ZFS provide for the claim to be covered by the agreed-to cap for September 11^th related losses provided to Converium by ZFS in conjunction with Converium’s Initial Public Offering.

Review of certain of Converium’s reinsurance transactions

F-45

and authorized the Restatement of Converium’s financial statements as of and for the years ended December 31, 2004 through 1998. As part of this process, the Audit Committee has involved its independent group auditors, PricewaterhouseCoopers Ltd. Financial information for each of the quarters ended March 31, 2003 through June 30, 2005 have also been restated. For further information regarding these accounting adjustments, please refer to Converium’s 2005 Annual Report (Note 3 to the 2005 consolidated financial statements for additional information on the Restatement). Previously published financial statements regarding any of the above periods should no longer be relied upon.

As noted above, Converium is fully cooperating with the governmental authorities and has shared the results of its internal review with the relevant authorities. Although the internal review was extensive, the ongoing governmental inquiries, or other developments, could result in further restatements of Converium’s financial results in the future and could have a material adverse effect on Converium.

Class action lawsuits

Following the Company’s announcement on July 20, 2004, that second quarter 2004 results would fall short of expectations due to higher than modeled U.S. casualty loss emergence primarily related to the underwriting years 1996 to 2001, six securities law class action lawsuits were brought against the Company and several of its officers and directors in the United States District Court for the Southern District of New York between October 4, 2004 and December 2, 2004 (collectively, the “Federal Actions”).

The Complaint names as defendants the Company; former directors Terry G. Clarke, Peter C. Colombo, Georg F. Mehl, George G.C. Parker, Derrell J. Hendrix and Anton K. Schnyder; former officers Dirk Lohmann, Martin Kauer and Richard Smith; former director Jürgen Förterer; ZFS; UBS AG; and Merrill Lynch International. The Complaint asserts claims for violations of Section 10(b) and Section 20(a) of the Securities Exchange Act of 1934 and Sections 11, 12 and 15 of the Securities Act of 1933 and alleges, among other things, that the Company misrepresented and omitted material information in various public disclosures during the period from December 11, 2001, through September 2, 2004 because the Company did not establish adequate loss reserves to cover claims by policyholders; that the Company’s announced reserve increases prior to July 20, 2004 were insufficient; and that, as a result of the foregoing, the Company’s earnings and assets were materially overstated. The putative class of plaintiffs on whose behalf these lawsuits have been asserted consists of all buyers of the Company’s stock from December 11, 2001, through and including September 2, 2004. Plaintiffs are seeking unspecified compensatory damages, attorney’s fees, witness fees and expert fees.

three of its former officers alleging that those defendants violated Section 10(b) and Section 20(a) of the Exchange Act by misrepresenting and omitting material information in various public disclosures following the Company’s initial public offering. Also on December 28, 2006, the Court denied plaintiffs’ motion to amend their complaint. The Court further ordered that the parties who remain in the actions, including the Company, engage in settlement discussions before a Magistrate Judge. A settlement conference took place before a Magistrate Judge on February 15, 2007 but did not result in a settlement.

Business Insurance Sector Inquiry by European Commission

Converium Rückversicherung (Deutschland) AG was selected by the European Commission as part of a sample of reinsurers for the purpose of a sector inquiry. The information request by the European Commission relates to business insurance, including reinsurance aspects, in the 25 member states of the European Union. The purpose of the inquiry is to determine whether competition in the business insurance sector works well.

21. Regulation

As a result of the developments in the latter part of 2004, various regulatory actions have occurred, the most significant of which are set forth below:

Switzerland

Converium AG has received an operating license from the Federal Office of Private Insurance (Bundesamt für Privatver-sicherungen) (the “FOPI”), an administrative unit of the Swiss Ministry of Finance (Eidgenössisches Finanzdepartment) and is subject to the continued supervision by the FOPI pursuant to the Swiss Insurance Supervisory Act of December 17, 2004 (Versicherungsaufsichtsgesetz) (“ISA”). The FOPI has supervisory authority as well as the authority to make decisions to the extent that the Swiss Ministry of Finance is not explicitly designated by law. On January 1, 2006 a completely revised ISA together with an Implementing Ordinance entered into force. The main changes are an amended definition of solvency (Art. 9) which includes consideration of financial and operational risks, an emphasis on the control of corporate governance elements by the FOPI and an increased transparency and consumer protection. The most important new feature is the introduction of the Swiss Solvency Test (“SST”), a risk-based capital model which preempts the forthcoming changes in the EU based upon the EU Solvency II Directive. Insurance undertakings are allowed to use their internal models if they comply with certain conditions of a qualitative, quantitative and organizational nature defined and accepted by the FOPI.

By letter dated September 27, 2004 the FOPI has requested that Converium AG provide notice on certain inter-group transactions between Converium AG and its subsidiaries including loans, guarantees, cost-sharing agreements, capital injections and investments in subsidiaries. Furthermore the FOPI requested by letter dated October 14, 2004 certain additional information including Converium’s business strategy, planning, reserves, solvency and collateral issues. Converium is cooperating with the FOPI and is providing all required information and documentation.

In December 2004, per the FOPI’s request, Converium AG agreed to submit for approval the following inter-group transactions: inter-group loans and capital increases to subsidiaries exceeding USD 100.0 million; guarantees exceeding USD 10.0 million; transfer of portfolios or novations involving changes in reserves exceeding USD 25.0 million, dividends to Converium Holding AG and all inter-group reinsurance transactions that are not at arm’s length. Absent consent of the FOPI, the inter-group transactions exceeding the thresholds could not be executed, which may in turn have an impact on the funding in conjunction with inter-group transactions.

Germany

On November 16, 2005, the European parliament adopted new European Union (“EU”) reinsurance guidance, which has to be transferred into national law by the end of 2007. This guidance basically deals with items such as solvency requirements, jurisdiction of the supervisory authorities within the EU, European passports for reinsurers, licenses and financial reinsurance.

Many of those items have already been implemented in Germany, foremost into the newly released German Insurance Supervision Act as of January 1, 2005. This law now includes solvency requirements for reinsurers based on the Solvency I standard as well as license and many jurisdictional items in great detail. The remaining items have been prepared for a white paper, which is expected to pass the German parliament in spring 2007 and to be released by end of 2007.

In addition, extensive work has been initiated by the local German supervisory authority and the German insurance association in order to prepare for a risk based solvency system

F-47

(Solvency II), which should be similar to the Basel II requirements enacted for the banking industry. Solvency II is not expected to be released prior to 2008/2009. There are some ambitious efforts to try to harmonize those requirements with the non-EU country Switzerland, which is preparing the Swiss Solvency Test (SST) in parallel.

Glossary

Accident and Health: All types of covers that provide benefits related to an accident or to medical treatments. Accident covers provide indemnification for damages caused by an accident such as accidental death and dismemberment, disability, medical expenses and the accumulation of accident-related benefits. Medical benefits may cover hospitalization expenses and outpatient expenses caused by any reason, dental treatments or medical expenses arising while traveling abroad. Also certain types of short-term income replacements such as hospital cash benefits are considered as health business.

Agribusiness: Agribusiness (re)insurance provides comprehensive coverage against crop yield shortfalls from natural perils in the form of Multi Peril Crop Insurance (MPCI) and Named Peril Covers for specialist crops. Other main products include insurance solutions for livestock portfolios, timber plantations, aquaculture risks, algae blooms and diseases and comprehensive coverage for greenhouse portfolios including crop content. Converium also develops innovative risk solutions for target markets and has recently introduced MPCI to the Brazilian and Italian market through its global experience in all major lines of agribusiness.

Annuity: A contract that pays a periodic income benefit for the life of a person (the annuitant) or for a specified number of years, or a combination of the two, in return for a single premium payment. Immediate annuities provide income from the date the policy is taken out and deferred annuities provide income at a future specified date.

Aviation & Space: Aviation insurance covers property and liability risks related to aircraft, airlines, aviation product manufacturers, airports, and related businesses. Space insurance covers losses during the pre-launch, launch, and in-orbit phases of satellites.

Branch Office: A branch office is part of the legal entity under which it operates and has its own organization and administration. It underwrites business for its assigned territory, has its own balance sheet and is subject to local regulations. Converium Ltd has branch offices in Singapore, Labuan, Bermuda and Australia. Converium Rückversicherung (Deutschland) AG has branch offices in Paris and Milan.

Cede, Ceding Insurer, Cession: When an insurer reinsures its risk with another insurer (“cession”), it “cedes” business and is referred to as the “ceding insurer.”

Combined Ratio: The sum of the loss ratio and the expense ratio for a non-life insurance or a reinsurance company. A combined ratio below 100 generally indicates profitable underwriting. A combined ratio over 100 indicates unprofitable underwriting. An insurance company with a combined ratio over 100 may be profitable to the extent that net investment results exceed underwriting losses.

Credit & Surety: Credit insurance, the insurance of commercial receivables, covers financial losses to insureds arising from debts which are uncollectible due to their customers’ insolvency. Surety insurance provides a guarantee to a third party, the beneficiary, that the principal — a construction company, for example — will fulfill an obligation to the beneficiary, who receives an indemnification if the principal fails to fulfill the obligation.

Cycle Management: Cycle Management is a process of dynamic and proactive assessment of the industry underwriting cycles, and our deployment of appropriate strategies to maximize Converium’s positioning and profitability throughout the cycles.

Engineering: Insurance covering building projects and the insurance of machinery in operation in industrial facilities.

Expense Ratio: The ratio of non-life insurance or reinsurance operating expenses (i.e. acquisition costs and profit participation net of reinsurance commissions) to net premiums earned plus administration expenses to net premiums written.

Facultative Reinsurance: The reinsurance of part or all of the insurance provided by a single policy negotiated on a contract-by-contract basis.

Fronting: Most commonly refers to the practice of a non-admitted insurer contracting with a licensed insurer to issue an insurance policy for regulatory or certification purposes. Subsequently, the risk is transferred to a reinsurance company by way of a reinsurance contract also known as a fronting agreement. The insured receives a policy written by the licensed commercial insurer, but the economic risk of that policy resides in the reinsurance company, although the ultimate liability remains with the fronting insurer.

In some jurisdictions, it is a legal requirement for either all, or certain classes' of business, to be written by a local insurer. Hence, if the reinsurer is established in a domicile other than that where the risk resides, then fronting arrangements are mandatory.

General Third Party Liability / Casualty: General liability business covers the (re)insurance of risks arising from commercial, product, business and personal liability.

Global Business Segments: Converium’s structure comprises three global business segments, based upon which Converium pursues its financial reporting and manages its business. The three global business segments are the following: Standard Property & Casualty Reinsurance, Specialty Lines, and Life & Health Reinsurance.

Gross Premiums Written: Total premiums (whether or not earned) for insurance contracts written or assumed (including deposits for contracts with an insignificant amount of mortality or morbidity risk) during a specific period, without deduction for premiums ceded.

G-1

Incurred But Not Reported (IBNR) Reserves: Reserves for estimated losses and loss adjustment expenses which have been incurred but not reported to the insurer or reinsurer, including future development of claims which have been reported to the insurer or reinsurer but where the established reserves may ultimately prove to be inadequate.

Liability: Liability insurance includes many classes of cover which provide indemnification for monetary amounts that an insured becomes legally obliged to pay to a third party.

Life and Disability: This includes all traditional and universal life covers, annuities, long-term care benefits, critical illness covers as well as all insurance types covering disability (long-term, short-term, permanent total, permanent partial, any/own occupation, etc.) caused by illness or accident.

Life & Health Reinsurance: Life & Health Reinsurance is one of the three global business segments Converium is based upon. This segment includes the following lines of business: Life and Disability, and Accident and Health.

Loss: An insured event that is the basis for submission or payment of a benefit under an insurance policy. Losses may be covered, limited or excluded from coverage, depending on the terms of the policy.

Loss Adjustment Expenses (LAE): The expenses of investigating and settling claims, including certain legal and other fees, and the expenses of administering the claims adjustment process.

Loss Ratio: Ratio of non-life insurance or reinsurance company’s net incurred losses and loss adjustment expenses to net premiums earned.

Loss Reserves: Reserves established by an insurer or reinsurer and recorded on its balance sheet to reflect the estimated cost of future payments for claims for which the insurer or reinsurer ultimately will be required to indemnify insureds or reinsureds in the future. Reserves are held in respect of losses occurred on or prior to the balance sheet date on insurance or reinsurance written and earned. Loss reserves are generally composed of individual case reserves for reported claims and IBNR reserves.

Marine & Energy: Marine insurance includes physical damage insurance for ships, shipping, oil rigs and related activities, cargo (while being transported by land, sea or air) and related liabilities.

Motor: Motor insurance covers claims for bodily injury and property damage arising from automobile accidents.

Net Premiums Written: Gross premiums less premiums ceded for reinsurance.

Non-Proportional Reinsurance: Reinsurance under which the reinsurer’s participation in a claim depends on the size of the claim. Also known as ”excess reinsurance”.

Personal Accident: All types of benefits insured on a stand-alone basis that provide indemnification related to an accident. The covered risks include accidental death and dismemberment, disability due to an accident (short-term, permanent total, permanent partial), medical expenses caused by an accident and the accumulation of accident-related benefits.

Premiums Earned: That portion of gross premiums written in current and past periods applying to the expired portion of the policy period.

Professional Liability and other Special Liability: Insurance to protect the insured against the consequences of its liability to pay damages in respect of a breach of professional duty in the practicing of its profession.

Property: Property insurance covers the physical assets of an insured against fire, extended coverages or all risks and consequential business interruption arising therefrom.

Proportional Reinsurance: Arrangement whereby the insurer cedes to the reinsurer an agreed fixed percentage of premiums, claims and other liabilities for each policy covered on a pro rata basis.

Reinsurance: The practice whereby one insurer, called the reinsurer, in consideration for premiums received, agrees to indemnify the ceding insurer for all or a portion of the risk under a policy or policies of insurance issued by the ceding insurer. The legal rights of the insured generally are not affected by the reinsurance transaction, and the insurance enterprise issuing the insurance contract remains liable to the insured for payment of policy benefits.

Representative Office: Representative offices provide Converium’s business segments with local bases for marketing, liaison and client service. They are restricted in their activities and may not underwrite reinsurance business. Converium has representative offices in Argentina, Brazil and Japan.

G-2

Reserves: Liabilities established by insurers and reinsurers to reflect the estimated cost of claims payments, benefits payments and the related expenses that the insurer or reinsurer will ultimately be required to pay in accordance with the insurance or reinsurance it has written.

Retention: The amount or portion of risk which a ceding insurer retains for its own account. Losses and loss expenses paid by the ceding insurer in excess of the retention level are then reimbursed to the insurer by the reinsurer. In proportional insurance, the retention may be a percentage of the original policy’s limit. In non-proportional insurance, the retention is an amount of loss, a loss ratio or a percentage.

Retrocessional Reinsurance: An arrangement under which a reinsurer cedes to another reinsurer (the “retrocessionaire”) all or a portion of the insurance risks reinsured by the first reinsurer. Retrocessional reinsurance generally does not legally discharge the ceding reinsurer from its liability to the original ceding company.

Specialty Lines: Specialty Lines is one of the three global business segments Converium is based upon. This segment includes the following lines of business: Agribusiness, Aviation & Space, Credit & Surety, Engineering, Marine & Energy, Professional Liability and other Special Liability, Excess and Surplus Lines, and Workers’ Compensation.

Standard Property & Casualty Reinsurance: Standard Property & Casualty Reinsurance is one of the three global business segments Converium is based upon. This segment includes the following lines of business: General Third Party Liability / Casualty, Motor, Property, and Personal Accident (assumed from non-life insurers).

Survival Ratio: An industry measure of the number of years it would take a company to exhaust its asbestos and environmental reserves for losses and loss expenses based on that company’s current level of asbestos and environmental claims payments. The ratio is derived by dividing the current ending losses and loss expense reserves by the average annual payments for the prior three years. The ratio is computed based on the ending reserves for losses and loss expenses over the respective claims settlements during the fiscal year.

Tail: The period of time that elapses between the incurrence and settlement of losses under a policy. A “short-tail” insurance product is one where ultimate losses are known and settled comparatively quickly; ultimate losses under a “long-tail” insurance product are sometimes not known and settled for many years.

Term Life Insurance: Life insurance protection for a limited period which expires without maturity value if the insured survives the period specified in the policy.

Treaty Reinsurance: A type of reinsurance whereby the ceding company automatically cedes and the reinsurer automatically assumes a predetermined portion or category of specified risks underwritten by the ceding company.

Underwriting: The process whereby an insurer or reinsurer reviews applications submitted for insurance or reinsurance coverage and determines whether it will provide all or part of the coverage being requested for an agreed premium.

Underwriting Results: The pre-tax profit or loss experienced by a non-life insurance company or reinsurance company after deducting incurred losses and loss expenses and operating expenses from premiums earned. This profit and loss calculation includes reinsurance assumed and ceded but excludes investment income.

Universal Life Insurance: A life insurance product under which premiums are generally flexible, the level of death benefits may be adjusted and expenses and other charges are specifically disclosed to the policyholder and deducted from their account balance.

Whole Life Insurance: A permanent life insurance product offering guaranteed death benefits and guaranteed cash values.

Workers’ Compensation: Workers’ compensation insurance provides payments required by law to be made to an employee who is injured or disabled in connection with work, including payments for both medical treatment and lost wages.
