### CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This prospectus contains forward-looking statements that are intended to enhance the reader’s ability to assess our future financial and business performance. These statements are based on the beliefs and assumptions of our management, and are subject to known and unknown risks and uncertainties. Generally, statements that are not about historical facts, including statements concerning our possible or assumed future actions or results of operations, are forward-looking statements. In particular, statements that use the words such as “believe,” “anticipate,” “expect,” “assume,” “objective,” “target,” “plan,” “estimate,” “project,” “seek,” “will,” “may,” “aim,” “likely,” “continue,” “intend,” “guidance,” “outlook,” “trends,” “future,” “could,” “would,” “should,” “target,” “predict,” “potential,” “on track” or their negatives or variations and similar terminology and words of similar import generally involve forward-looking statements. These statements reflect our current views with respect to future events and because our business is subject to numerous risks, uncertainties and other factors, our actual results could differ materially from those anticipated in the forward-looking statements. We believe that these factors include, but are not limited to, the following:

• the occurrence of natural disasters, severe weather events and other catastrophic events;

• global climate change and government responses thereto;

• war, terrorism and political unrest, government action that is hostile to commercial interests and from sovereign, sub-sovereign and corporate defaults;

• emerging claim and
