Important Disclaimers

This document contains forward-looking statements as defined in the U.S. Private
Securities Litigation Reform Act of 1995. It contains forward-looking statements
and information relating to the Company's financial condition, results of
operations, business, strategy and plans, based on currently available
information. These statements are often, but not always, made through the use of
words or phrases such as `seek to', `expects', `aims' `should continue',
`believes', `anticipates', `estimates' and `intends'. The specific
forward-looking statements cover, among other matters, our combined ratio,
return on equity and premium volume and expense reduction targets, our plans to
use capital more efficiently and to return capital to shareholders, the
reinsurance market, the Company's operating results, the Company's dividend
policy, our ability to obtain an upgrade of our financial strength rating and
the consequences of such an upgrade, the prospects for improving our results,
investment yield and market share. Such statements are inherently subject to
certain risks and uncertainties. Actual future results and trends could differ
materially from those set forth in such statements due to various factors. Such
factors include whether we are able to secure an upgrade of our financial
strength ratings; our ability to refinance our outstanding indebtedness and
increase our use of hybrid capital; uncertainties of assumptions used in our
reserving process; risk associated with implementing our business strategies and
our capital improvement measures; cyclicality of the reinsurance industry; the
occurrence of natural and man-made catastrophic events with a frequency or
severity exceeding our estimates; acts of terrorism and acts of war; changes in
economic conditions, including interest and currency rate conditions that could
affect our investment portfolio; actions of competitors, including industry
consolidation and development of competing financial products; a decrease in the
level of demand for our reinsurance or increased competition in our industries
or markets; our ability to expand into emerging markets; our ability to enter
into strategic investment partnerships; a loss of our key employees or executive
officers without suitable replacements being recruited within a suitable period
of time; our ability to address material weaknesses we have identified in our
internal control environment; political risks in the countries in which we
operate or in which we reinsure risks; the passage of additional legislation or
the promulgation of new regulation in a jurisdiction in which we or our clients
operate or where our subsidiaries are organized; the effect on us and the
insurance industry as a result of the investigations being carried out by the US
Securities and Exchange Commission, New York's Attorney General and other
governmental authorities; our ability to regain past customers following any
rating upgrades and the resolution of the investigations being carried out by
the US Securities and Exchange Commission, New York's Attorney General and other
governmental authorities; changes in our investment results due to the changed
composition of our invested assets or changes in our investment policy; failure
of our retrocessional reinsurers to honor their obligations or changes in the
credit worthiness of our reinsurers; our failure to prevail in any current or
future arbitration or litigation; and extraordinary events affecting our
clients, such as bankruptcies and liquidations, and other risks and
uncertainties, including those detailed in the Company's filings with the U.S.
Securities and Exchange Commission (including, but not limited to, our Annual
Report on Form 20-F filed with the U.S. Securities and Exchange Commission) and
the SWX Swiss Exchange. The Company does not assume any obligation to update any
forward-looking statements, whether as a result of new information, future
events or otherwise.
