CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS
This quarterly report and the documents incorporated by reference herein contain statements that constitute "forward-looking statements" within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, with respect to our financial condition, results of operations, business strategies, operating efficiencies, competitive positions, growth opportunities, plans and objectives of our management, as well as the markets for our securities and the insurance and reinsurance sectors in general.
Statements that include words such as "estimate," "project," "plan," "intend," "expect," "anticipate," "believe," "would," "should," "could," "seek," "may" and similar statements of a future or forward-looking nature identify forward-looking statements for purposes of the federal securities laws or otherwise.
All forward-looking statements are necessarily estimates or expectations, and not statements of historical fact, reflecting the best judgment of our management and involve a number of risks and uncertainties that could cause actual results to differ materially from those suggested by the forward-looking statements.
These forward looking statements should, therefore, be considered in light of various important factors, including those set forth in this report and in our Annual Report on Form 10-K for the year ended December 31, 2023, which could cause actual results to differ materially from those suggested by the forward-looking statements. These risk factors include:
the completion of the Merger (as defined herein) on the anticipated terms and timing;
the satisfaction of other conditions to the completion of the Merger, including obtaining required shareholder and regulatory approvals;
the risk that our stock price may fluctuate during the pendency of the Merger and may decline if the Merger is not completed;
potential litigation relating to the Merger that could be instituted against us or our directors, managers or officers, including the effects of any outcomes related thereto;
the risk that disruptions from the Merger (including the ability of certain customers to terminate or amend contracts upon a change of control) will harm our business, including current plans and operations, including during the pendency of the Merger;

the possibility that the Merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events;
unexpected costs, liabilities or delays associated with the Merger;
the response of competitors to the Merger;
the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger, including in circumstances requiring us to pay a termination fee;

risks relating to our ability to structure our investments in a manner that recognizes our liquidity needs;
risks relating to our strategic investments in alternative asset classes and joint ventures, which are illiquid and may be volatile;
