See our 2024 Annual Report on Form 10-K, Item 8, Note 13, Employee Retirement Benefits, Page 167, for information on our retirement benefits. The net periodic benefit is allocated in the same proportion primarily to the underwriting, acquisition and insurance expenses line item with the remainder allocated to the insurance losses and contract holders' benefits line item on the condensed consolidated statements of income for both 2025 and 2024.

We made matching contributions totaling $8 million and $7 million to our 401(k) and Top Hat savings plans during the second quarter of 2025 and 2024, respectively, and contributions of $19 million and $16 million for the first half of 2025 and 2024, respectively.
We made no contributions to our qualified pension plan during the first six months of 2025.
