Material Changes vs. Prior Period
- Investment Income Decline: Total investment income decreased by 8.2% in Q3 2025 compared to Q3 2024, primarily due to a decrease in reference rates (SOFR) and lower interest income from investments. YTD 2025 income also declined 5.0% compared to YTD 2024.

- Realized Losses: The company reported net realized losses of $36.6 million for the nine months ended September 30, 2025, contrasting with net realized gains of $3.9 million in the same period in 2024. This was driven by specific investment exits and foreign currency transaction impacts.
