CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

In addition to historical information, this Annual Report on Form 10-K contains forward-looking statements intended to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. Such statements, including statements about our plans, objectives, expectations, assumptions or future events, involve risks and uncertainties. These statements involve estimates, assumptions, known and unknown risks, uncertainties and other factors that could cause actual results to differ materially from any future results, performances or achievements expressed or implied by the forward-looking statements. Typically, forward-looking statements can be identified by terminology such as “anticipate,” “estimate,” “plan,” “project,” “continuing,” “ongoing,” “expect,” “believe,” “intend,” “may,” “will,” “should,” “could,” and similar expressions. The important factors that could cause actual results to differ materially from those indicated by such forward-looking statements include but are not limited to the effects of governmental regulation; changes in insurance regulations; the frequency and extent of claims; uncertainties inherent in reserve estimates; catastrophic events; changes in the demand for, pricing of, availability of or collectability of reinsurance; restrictions on our ability to change premium rates; increased rate pressure on premiums; the severity and impact of cybersecurity incidents; and other risks and uncertainties and other factors listed under Item 1A – “Risk Factors” and elsewhere in this Annual Report on Form 10-K and in our other Securities and Exchange Commission filings. You are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date they are made and are not guarantees of future performance. Except as required by applicable securities laws, we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
