and our ability to manage catastrophe risk • Risks associated with analytical models in key areas such as underwriting, pricing, capital management, reserving, investments, reinsurance, and catastrophe risk management • Inadequate estimates or assumptions, or reliance on third-party data used for critical accounting estimates • Events or conditions that could weaken or harm our relationships with our independent agencies and hamper opportunities to add new agencies, resulting in limitations on our opportunities for growth • Mergers, acquisitions, and other consolidations of agencies that result in a concentration of a significant amount of premium in one agency or agency group and/or alter our competitive advantages • Our inability to manage business opportunities, growth prospects, and expenses for our ongoing operations • Changing consumer insurance-buying habits • The inability to obtain adequate ceded reinsurance on acceptable terms, for acceptable amounts, and from financially strong reinsurers; and the potential for nonpayment or delay in payment by reinsurers • Domestic and global events, such as the wars in Ukraine and in the Middle East, future pandemics, inflationary trends, changes in U.S. trade and tariff policy, and disruptions in the banking and financial services industry, resulting in insurance losses, capital market or credit market uncertainty, followed by prolonged periods of economic instability or recession, that lead to: ◦ Securities market disruption or volatility and related effects such as decreased economic activity and continued supply chain disruptions that affect our investment portfolio and book value ◦ Significant or prolonged decline in the fair value of securities and impairment of the assets ◦ Significant decline in investment income due to reduced or eliminated dividend payouts from securities ◦ Significant rise in losses from surety or director and officer policies written for financial institutions or other insured entities or in losses from policies written by Cincinnati Re or Cincinnati Global ◦ An unusually high level of claims in our insurance or reinsurance operations that increase litigation-related expenses ◦ Decreased premium revenue and cash flow from disruption to our distribution channel of independent agents, consumer self-isolation, travel limitations, business restrictions and decreased economic activity ◦ The inability of our workforce, agencies, or vendors to perform necessary business functions Financial, Economic, and Investment Risks • Declines in overall stock market values negatively affecting our equity portfolio and book value • Downgrades in our financial strength ratings • Interest rate fluctuations or other factors that could significantly affect: ◦ Our ability to generate growth in investment income ◦ Values of our fixed-maturity investments and accounts in which we hold bank-owned life insurance contract assets ◦ Our traditional life policy reserves • Economic volatility and illiquidity associated with our alternative investments in private equity, private credit, real property, and limited partnerships • Failure to comply with covenants and other requirements under our credit facilities, senior debt, and other debt obligations • Recession, prolonged elevated inflation, or other economic conditions resulting in lower demand for insurance products or increased payment delinquencies • The inability of our subsidiaries to pay dividends consistent with current or past levels impacting our ability to pay shareholder dividends or repurchase shares General Business, Technology, and Operational Risks • Ineffective information technology systems or failing to develop and implement improvements in technology • Difficulties with technology or data security breaches, including cyberattacks, could negatively affect our, or our agents’, ability to conduct business;
