Accordingly, the information in Item&nbsp;7.01 of this report will not be incorporated by reference into any registration

<P align="left" style="font-size: 10pt; text-indent: 2%">Any forward-looking statements made in the presentation in Exhibit&nbsp;99.1 reflect our current views with respect to
future events and financial performance and are made pursuant to the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995. Such statements involve risks and uncertainties, which may cause actual results to
differ materially from those set forth in these statements. For example, our forward-looking statements could be
affected by the ability to recognize the benefits of the Darwin Professional Underwriters, Inc. acquisition; pricing
and policy term trends; increased competition; the impact of acts of terrorism and acts of war; greater frequency or
severity of unpredictable catastrophic events; investigations of market practices and related settlement terms;
negative rating agency actions; the adequacy of our loss reserves; the Company or its subsidiaries becoming subject to
significant income taxes in the United States or elsewhere; changes in regulations or tax laws; changes in the
availability, cost or quality of reinsurance or retrocessional coverage; adverse general economic conditions; and
judicial, legislative, political and other governmental developments, as well as management&#146;s response to these
factors, and other factors identified in our filings with the U.S. Securities and Exchange Commission. You are
cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date on which
they are made. We are under no obligation (and expressly disclaim any such obligation) to update or revise any
forward-looking statement that may be made from time to time, whether as a result of new information, future
developments or otherwise.
