Our ability to successfully execute business functions also depends on hiring and retaining the qualified associates we employ. Competition for high-quality executives and other key associates occurs within the insurance industry and from other industries. We also must effectively develop and manage associates, including providing training and resources. Such tools and information can allow them to effectively perform critical business functions and adapt to changing business needs. During tight labor markets, such as we experienced in recent years, there is intense competition for associates qualified to execute important business functions. Many markets in which we operate are experiencing a low unemployment rate and labor shortages are affecting many industries. If we are unable to attract and retain certain associates, or if we fail to provide adequate training or resources, or fail to provide a work environment that is attractive to associates, we could limit the success of executing our strategic plans and vital business functions. Additionally, loss of key personnel or an inability to successfully execute on succession plans could negatively impact growth, operating results, financial condition, essential business relationships, profitability, and other business operations.

Effective July 1, 2025, we purchased an additional layer on our 2025 property catastrophe reinsurance treaty with a limit of $300 million, increasing the total limit from $1.500 billion to $1.800 billion. We can recover up to $129 million under this coverage for a loss between $1.500 billion and $1.800 billion for a covered event occurring prior to July 1, 2026. The provisions of this additional layer are similar to those in the other layers of the 2025 property catastrophe treaty. The annual ceded premiums for this additional coverage are estimated to be less than $5 million.

•Catastrophe bonds – Effective January 2026, we purchased collateralized reinsurance funded through the issuance of collateralized insurance-linked securities, also known as catastrophe bonds. We entered into a reinsurance agreement with Skyline Re II Ltd. ("Skyline"), an independent Bermuda company registered as a special purpose insurer under the Bermuda Insurance Act of 1978. This agreement provides up to $150 million in reinsurance protection for an event between $1.000 billion and $1.800 billion with no reinstatement provision. This agreement is generally designed to supplement coverage provided under the property catastrophe treaty, however, terrorism and strike, riot, or civil commotion events are not covered. Skyline issued notes to unrelated investors for a total principal amount of $150 million, equal to the full reinsurance coverage provided under the reinsurance agreement. The proceeds of the issuance were deposited into a reinsurance trust account. The catastrophe bonds expire in January 2030. The reinsurance agreement meets the requirements to be accounted for as reinsurance in accordance with the guidance for reinsurance contracts.
